Every time talking about the movement of cheap rolex submariner watches, feels a little boring.Because it is not a very romantic thing, It always want to be involved in a lot of science with honours students to concern.But the topic today, believe me, even if just look at the map, you will feel surprise and fun.If you really like machinery. Today want to introduce is the mechanical movement inside some of the beads, in most people’s impression: “joke, in the movement which have beads, I hadn’t seen it.”
Rolex put tuo ball bearing automatically
Yes, when we are taught to appreciate the polishing of movement and structure, many small things can be ignored.The bead is one of them. Where is the movement of the beads? The most common, in automatic pendulum tuo of the bearing. This point I think general watches friends all know, but also know more? What are the advantages of ball bearing? In addition to the ball bearing, what magical beads in the movement?
The rolling ball bearing and love beads
What is a ball bearing? Baidu encyclopedia wikipedia and explain the very professional.It is easy to say it is a bearing with the beads. What’s the use of ball bearing? First of all, reduce the friction shaft and fixed layer, the second fixed and supporting parts. Said the structure of the bearing is not very complicated, simple is the middle of the inner ring and outer ring and the beads, there are some of the details, but it belongs to the category of mechanical precision manufacturing, we just need to know about it.
Its principle is very simple.In the past, still no rolling bearing (not only refers to the clock domain), general bearing shaft and fixed plate are direct friction.In order to use, just wipe on lubricating oil, lubricating oil in the long run will consume, and this is the sliding friction, once the lubricating oil, it will produce wear, finally can only in shaft. Ball bearing is the rolling friction, high school physics teacher said that the rolling friction than the sliding friction resistance is small.So the advantage is obvious.It is not only won’t produce high temperature, also can greatly reduce wear and tear. The first modern ball bearing patent records, is 1794 a welsh inventor and steel experts, used for axle.
Silicon nitride ceramic ball bearing
Ball bearing is the key to what? Is the magic ball in it. Ball is the most important part of the bearing, it determines the quality of the bearing, ball bearing on international have corresponding standards, from the G3 to G2000, ball surface more smooth and more good, more and more good. Ball, at the same time, different materials have different characteristics, such as the majority of the steel ball, need lubrication, high chrome steel and bearing some of special alloy steel, and silicon nitride ceramic ball, there is no need for lubrication, the coefficient of friction resistance because it is the best one, of course there are some other material also can reach this level, but its rockwell hardness is 70, is the highest hardness in mainstream ball bearing material.
Let the bead strings for you
Ball used in the movement, mainly automatically put the ball bearing in the vedas, currently on the market can meet most of the automatic pendulum tuo, using all of these ball bearings, specific what time to start, I don’t have any more, I don’t know is there any watches friends know? But one thing we all know, rolex and one of the most famous automatic movement Cal. 3135 with pin bearing, pin bearing use for a long time there will be wear and tear, caused many users of the machine core, the phenomenon of the automatic tuo cut ceng bottom plate (so need timely maintenance regularly, so as to loss the movement, so for a long period of time, everyone wants to rolex can use ball bearings instead of pin bearing.
Rolex 4130 automatic timing machine core roller tuo
Rolex, of course, the automatic timing movement Cal. 4130 early is ball bearing automatically put tuo, beginning in 2015, the rolex is a new generation of automatic machine core, Cal. 3255 and Cal. 3235 also is with the ball bearing. Other automatic movement including the most basic ETA movement, most with the ball pendulum tuo automatically. Remember a few years ago, when a lot of brand promotion independent automatic movement, which will be described, using ceramic ball bearing, it is an important technical means, but in recent years as if how do not see, is only that it was scared.
ETA 2824 ball bearing
Different automatic machine, automatic tuo ball bearing type is different, sometimes big sometimes small, which is suiwatches for, depending on the design of the movement itself, ETA ETA 2892 2824 and obvious difference is the automatic tuo ball bearing, ball bearing of patek philippe and Rolex, seiko and Vaucher is not the same, these are based on movement itself to determine the design and production. But consistent is, they are used in fixed automatic tuo won’t offset, at the same time, small friction helps self winding (bent to the difference between efficiency and its important influence factors is put the weight and structure of the vedas).
Another way of bead string
When most of the beads on the bearings for you in the chain, there are some nifty beads, their nature is restless. This is my first time to see such a creative, RM 007, the world famous high-tech tabulation brand Richard Mille’s a ladies watch. It can be said that almost all of the world on the automatic movement of pendulum tuo, are solid metal block as a heavy hammer, its center of gravity is fixed, and Richard Mille charm lies in the breakthrough.
RM 007 automatic tuo, internal with hundreds of the same size, shape of small metal beads, the beads can be placed in the automatic tuo in the framework of free rolling, its advantage is that when placed swing tuo, with beads inside the scroll, the pendulum is tuo focus will shift and close to the edge of the vedas, a top position increased moment of inertia. I didn’t say whether more effective, but this is a whole new way. Also formed a very interesting visual impact at the same time, for a female friend, inside beads can free rolling, with his arm swinging is too interesting.
When the beads affinity box spring
Even if you are lovers of mechanical movement, I think you don’t necessarily know, have a clockwork box should have ball bearing, it is a mechanical slasher dry out. In 2009, Eterna (Eterna) released a new machine, 3505 Spherodrive Calibre. This movement is very interesting, it will be ball bearing, applied to box spring up and down on the two points. Sorry, this really need to use the basic principle of mechanical movement.
Use the same ball bearing box spring eterna 3510 movement
Ordinary box spring, there is a few parts, internal spring, spring end attached to the middle of the shaft, the other end connected to a clockwork wall, and end on axis of the ratchet (or large steel wheel), fixed by the main substrate vertically below, clockwork wall is the lining of the entire box spring, spring box of outer wall has a tooth, also called a round box, box above the wheel has lifted the lid. Articles in general, shaft and lifted the lid and the main substrate of contact position, are using artificial ruby, point lubricating oil, because the shaft and the two position has a direct contact, there will be friction.
Ball bearing box spring structure
Eterna article will shaft to be exposed to these few points, all changed into the ball bearing, it is a bold attempt, because before this, also does not have heard of it, if please welcome know to watch friends leave a message). Obviously, jewel bearing and ball bearing is still there, jewel bearing need some lubricating oil, if it is a ceramic ball bearing is not, although the cost and technical difficulties have enhanced, benefit is longer service life.
Even more interestingly, eterna clockwork with this, is a double ball bearing structure, the inner ring with square openings, used to connect to the axis, the central by three screws in the bottom of the substrate, the outer ring with clockwork box fixed by three screws (there are three holes are three pin), and this is the first time to see on the clockwork box using screws. There is no doubt that this structure than simply a rubies bearing more complex, and occupy a lot of space, eterna clockwork box is superimposed to the dual ball bearing. Do really worth, with the cost to replace a small ruby? Anyway, this is a new attempt, in tiny technology development today, is this can be simplified. It also illustrates a problem, ruby bearing is not the most ideal way of bearing, it also has new possibilities.
Beads to dominant foothold in the movement
And the article above box of wheel, I think a lot of friends may also be the first to see such a structure, the jewel bearing use ball bearings instead of plywood. This is Japan’s independent watchmaker Hajime Asaoka’s flights of fancy. The Tourbillon Project T Tourbillon, T plan? This movement has 13 roller bearing, and 13 drill. This is so far I’ve seen most ball bearing movement, and is a manual machine, no ball bearing automatic tuo.
And the eterna in front of the ball bearing box spring has the same effect, but Hajime Asaoka the ball bearing used in the main gear train. Also, these bearings have the effect of reducing friction, on the one hand, on the other hand fixed and supporting structure of gear train. And, more importantly, he also used his ball bearing in the tourbillon this extremely sophisticated structure, it is a great adventure, it was also his TAB in the fun.
Simply to appreciate that, in fact, it is difficult for us to understand how difficult is it to replace ball bearings, if you now have a back through the watch in his hand, you can contrast carefully, this only the tourbillon movement of small ball bearing is about a third of ordinary screw surface area, which has a bearing around 6 to 7 star ball, you can imagine the ball how tiny, tiny to on the desktop, you stay away from him a foot distance can’t see with the naked eye. So it is of high precision micro fabrication technology, is worth watching. , of course, it is not he a man can do, this is he and cooperation between the two companies to make watches, a company called OSG Corporation, specializing in the production of high precision cutting tools, another name is Yuki, high precision mechanical equipment suppliers, the two companies provide him with the support of technology and equipment.
The beads are very gentle and graceful
In addition to the above, the ball in the mechanical movement, what the mysterious figure? Watch a bad for you. In 2014, bulgari to launch a ultra-thin tourbillon movement, Finissimo Caliber BVL 268, the world’s most BoTuo flywheel movement, it is only 1.95 mm thick, and a one usd coin thickness (1.85 mm). For a long time, ultra-thin is one of the countless watchmaker pursuit, because it represents a more compact structure, more precision parts, and more exquisite tabulation technology, it must be a solid structure.
Every pieces of ultra-thin movement, has not come easily, if you know some slightly the tourbillon, you should understand, ultra-thin tourbillon how hard it is to make, because a tourbillon structure may be more than the thickness. For ultra-thin, bulgari as far as possible to remove some plywood, and all the parts that are fixed in the main substrate as possible on both sides, this means that you need to give up traditional double fixed pattern on gear parts. To switch to fixed center directly, through a screw and a ball bearing can be achieved, sharply reduced the thickness, because some gear will no longer need to have a central axis.
With the help of the micro technology of precision manufacturing capability, bulgari chose ball bearings instead of part of ruby bearing. The naked eye is hard to perceive the mystery of the beads, played an amazing role again. In this movement, according to official data using the eight different ball bearings, including three use around the box spring, to double the height of the clockwork, store up to 52 hours.
Even more interestingly, bulgari instrument ball bearing applications to the tourbillon framework. Traditionally, floating the tourbillon is fixed at the bottom of the bearing, and bulgari this movement is a real floating type, have no fixed bearing, up and down around the tourbillon but outside the framework of fixed ball bearing and the main substrate, in a sense, its bearing surface more balanced, theoretically more solid than center fixed axis. Bulgari is this kind of machine, can do both thin, and can be the cause of the solid.
Besides the point as an aside, this movement has an interesting places, walking from the tourbillon to the center of the system are separated, not in a line of energy, the energy line is traditionally a body, and this movement, from spring to the tourbillon is a power line, walking from the spring to the center is another energy line. And also very interesting article on the dial needle system, a structure of a variety of purposes, is really clever.
Wrist watch also love to play jump beads
When the tiny beads in movement is popular at the time of big beads are also beginning to itch to try. An interesting independent watchmaker brand, Christophe Claret, deeply fan, if you are a venture must have heard of this name, its several representative works, to subvert the tradition of several advanced TAB. I don’t remember exactly what year, he created the X – this TREM – 1 a watches strange flower, the magnetic technology used in mechanical tabulation, traditionally, for magnetic is all.
The incomparable movement, using the magnetic drive, by silk pulling movement on both sides of the metal ball, moving slowly, to indicate the time. Both stainless steel metal ball (that’s right, compared with other beads, it is a ball), has a strict technical indicators, in order to lose weight so that in the range of magnetic force to control, the two small hollow metal ball center, surface coating. Floating tuo flywheel energy evenly split, provide accurate measurement for walking.
Product family movement with ball bearing
According to the present high precision micro mechanical processing technology, miniature ball bearings are totally without lubrication can be made, just the cost is very high, and rubies bearing is not a level, so ruby is still under the comprehensive consideration the ideal bearing fixed materials, but in advanced machine core, miniature ball bearings will be useful, it can improve the movements, as well as the entire thickness of the lubrication and solid. Only, it is so mechanization, no beautiful ruby.
