In diagram：1. accommodate the second pinion of 2. second pinion of clamping plate 3. set 31. jump ring mounting groove 32. packing ring installation position 33.
The jewel bearing of 4. packing ring of bearing installation position 5. covers the oil storage tank of 6. jewel bearing, 7. jump ring 8.
Embodiment
The embodiment of the present invention is further described below in conjunction with the accompanying drawings.
The attachment structure of second pinion and rotation body portion in a kind of flight tourbillon movement as shown in Figure 1, includes pendulum
Lower plate 1, second pinion 2, second pinion set 3, packing ring 4, jewel bearing set 5, jewel bearing 6, jump ring 7 and oil storage tank 8.
3 one end of second pinion set, which are fixed on, is accommodated on clamping plate 1, and second pinion 2, second pinion 2 and second pinion are fixed with the other end
It is interference fitted between set 3, forms stable fixed structure between second pinion 2 and second pinion set 3, it is not easy to loosen.
3 outer surfaces being covered in second pinion jewel bearing 6 being installed, jewel bearing 6 is mounted below for preventing jewel bearing 6
The jump ring 7 that moves up and down on second pinion set 3, is additionally provided with packing ring 4 between jewel bearing 6 and jump ring 7, jewel bearing 6,
Packing ring 4 and the outer ring of jump ring 7 are provided with jewel bearing set 5.
Jump ring installation position 31, packing ring installation position 32 and bearing installation position 33 on second pinion set 3 are diametrically from small to large
Hierarchic structure, wherein, all consistent straight barrel type structure of integral overall diameter is directly done, it is necessary to ensure compared to by second pinion set 3
Second pinion, which covers 3 outer surfaces, very high machining accuracy, just can ensure that jewel bearing 6 and packing ring 4 will not go out when installation
Current situation portion is interference fitted, and unnecessary difficulty is carried out to assembled belt；And stepped construction is much lower to the requirement on machining accuracy of entirety,
The high-precision can on guarantee jewel bearing 6 installation site surface is only needed, other are such as the installation site of packing ring 4 and jump ring 7
The roughness and machining accuracy on surface relative can lower requirement, reduce also square while the processing cost of second pinion set 3
Last assembly and disassembly, only need to by jewel bearing 6, packing ring 4 and jump ring 7 successively from big to small set be connected to specific installation
Position can, lower the convenient rotation precision for not influenceing jewel bearing 6 again.
Jump ring 7 is groove profile in the installation site section of second pinion set 3, when jump ring 7 is arranged in groove, except jump ring 7 and second
Outside coupling mechanism force between tooth axle sleeve 3, rectangular channel lower edge also to jump ring 7 play support and position-limiting action, ensure that jump ring 7 with
The fastness and stability that second pinion set 3 coordinates.
The lower surface of packing ring 4 is in contact with the upper surface of jump ring 7, the diameter on installation site surface of the packing ring 4 on second pinion set 3
More than the diameter that jump ring 7 installs rooved face.The diameter of installation site of the jewel bearing 6 on second pinion set 3 is more than the peace of packing ring 4
Diameter is filled, lower surface and the upper surface of packing ring 4 of jewel bearing 6 have gap, and ensureing will not be because of unnecessary when jewel bearing 6 rotates
Frictional force and influence the rotation precision of jewel bearing 6.In addition, the upper surface of packing ring 4 is also hierarchic structure, the outside of packing ring 4 is high
Degree is significantly less than inner side, so only needs to ensure the high-precision surface in 4 high portion of packing ring, and it is normal that the surface accuracy of lower curtate, which ensures,
Level of processing can, the overall processing difficulty of packing ring is reduced, only need to ensure to need the local surfaces precision of part, so as to
Reduce production cost.
Second pinion covers 3 outer surfaces, and oil storage tank 8, the ring second pinion of oil storage tank 8 are provided with close to the position of the coboundary of jewel bearing 6
Cover 3 outer surfaces one to enclose, the lower boundary of oil storage tank 8 and the coboundary of jewel bearing 6 connect, and in timed maintenance, lubricating oil is added to
In oil storage tank 8, the lubricating oil in oil storage tank 8 can be carried out along gap between jewel bearing 6 and second pinion set 3 to jewel bearing 6
Lubrication.The oil storage performance that second pinion covers 3 outer surfaces is before timepiece movement is assembled, and second pinion set 3 is immersed in into perfluor zincic acid chromium
In solution, then dry, baking is dry, and so oil will get together in second pinion set
When needing that jewel bearing 6 is removed inspection or safeguarded, jump ring 7 is unclamped using instrument, takes out jump ring 7 and packing ring
4, finally take out jewel bearing 6 and jewel bearing set 5, it is possible to achieve separate, be easy between the jewel and rotary body of fixed position
Carry out dismounting maintenance, this structure have it is simple in construction, reliably, easily operation, can be with volume production the advantages of.
As described above, the only specific embodiment of the invention, it is impossible to as limiting present invention specific implementation scope, all
The change and modification made according to the claims in the present invention and description, all within the scope of the present invention.
