Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
The syndeton of second pinion and rotary body part in a kind of tourbillon movement that flies as shown in Figure 1, includes and accommodates clamping plate 1, second pinion 2, second pinion cover 3, packing ring 4, jewel bearing cover 5, jewel bearing 6, jump ring 7 and oil storage tank 8.
Second pinion overlaps 3 one end and is fixed on and accommodates on clamping plate 1, and other end internal fixtion has second pinion 2, interference fit between second pinion 2 and second pinion cover 3, forms stable fixed sturcture, be not easy to loosen between second pinion 2 and second pinion cover 3.
Overlap 3 outside surfaces at second pinion and jewel bearing 6 is installed, jewel bearing 6 is provided with the jump ring 7 for preventing jewel bearing 6 from moving up and down on second pinion cover 3 below, also be provided with packing ring 4 between jewel bearing 6 and jump ring 7, be provided with jewel bearing cover 5 in jewel bearing 6, packing ring 4 and jump ring 7 outer ring.
Jump ring installation position 31 on second pinion cover 3, packing ring installation position 32 and bearing installation position 33 diametrically staircase structure from small to large, wherein, the all consistent straight barrel type structure of integrally overall diameter is directly done compared to by second pinion cover 3, need to ensure that second pinion overlaps 3 outside surfaces and has very high machining precision, just can guarantee that jewel bearing 6 and packing ring 4 there will not be local interference fit when installation, bring unnecessary difficulty to assembling; And the requirement on machining accuracy of stepped construction to entirety is much lower, only need the high precision ensureing surface, jewel bearing 6 installation site just passable, other can be lowerd requirement relatively as the roughness on packing ring 4 and the surface, installation site of jump ring 7 and machining precision, also last assembly and disassembly are facilitated while reducing the processing cost of second pinion cover 3, only need bearing 6 of acknowledging sb. as one's master, packing ring 4 and jump ring 7 successively from big to small cover to receive specific installation site just passable, lower the rotation precision conveniently not affecting again jewel bearing 6.
Jump ring 7 is grooved in the cross section, installation site of second pinion cover 3, when jump ring 7 is arranged in groove, except the coupling mechanism force between jump ring 7 and second pinion cover 3, support and position-limiting action are also played to jump ring 7 in rectangular channel lower edge, ensure that jump ring 7 and second pinion overlap 3 fastness coordinated and stability.
Packing ring 4 lower surface contacts with jump ring 7 upper surface, and the diameter on the installation site surface of packing ring 4 on second pinion cover 3 is greater than the diameter on jump ring 7 mounting groove surface.The diameter of the installation site of jewel bearing 6 on second pinion cover 3 is greater than the installation diameter of packing ring 4, there is gap in lower surface and packing ring 4 upper surface of jewel bearing 6, ensures that jewel bearing 6 can not affect the rotation precision of jewel bearing 6 because of unnecessary friction force when rotating.In addition, the upper surface of packing ring 4 is also staircase structure, packing ring 4 outside height is significantly less than inner side, so only need the high-precision surface ensureing the high portion of packing ring 4, and the surface accuracy of lower curtate ensures as normal process level is just passable, reduce the overall processing difficulty of packing ring, only need ensure the local surfaces precision of needs part, thus reduce production cost.
Second pinion overlaps 3 outside surfaces, the position of next-door neighbour jewel bearing 6 coboundary has oil storage tank 8, oil storage tank 8 ring second pinion overlaps 3 outside surface one circles, oil storage tank 8 lower boundary and jewel bearing 6 coboundary connect, when timed maintenance, joined by lubricating oil in oil storage tank 8, the lubricating oil in oil storage tank 8 can lubricate along gap between jewel bearing 6 and second pinion cover 3 jewel bearing 6.The oil storage performance that second pinion overlaps 3 outside surfaces is before assembling timepiece movement, and be immersed in perfluor zincic acid chromium solution by second pinion cover 3, then dry, baking is dry, and oil will be got together at second pinion cover like this
When needing jewel bearing 6 removed inspection or safeguard, use instrument unclamps jump ring 7, take out jump ring 7 and packing ring 4, finally take out jewel bearing 6 and jewel bearing cover 5, can realize being separated between the jewel of fixed position and rotary body, be convenient to carry out dismounting maintenance, this structure has structure simple, reliably, easily operate, can the advantage of volume production.
As mentioned above, be only the specific embodiment of the invention, can not as restriction the present invention concrete practical range, all changes of doing according to the claims in the present invention and description and amendment, all in protection scope of the present invention.
