参见图6〜图8,在自动上发条时钟的机芯中,旋转杆的球轴承部即球轴承962具有内圈968、保持圈970和外侧圈即外圈972。 Referring to FIG. 6 ~ FIG. 8, in a self-winding movement clock, the ball bearing of the rotary shaft 962, i.e., ball bearings having an inner ring 968, retaining ring 970 and the outer ring outer ring 972. 保持圈970 固定于内圈968上。 Retaining ring 970 is fixed to the inner ring 968. 因此,内圈968与保持圈970构成内侧圈。 Thus, the inner ring 968 and retaining ring 970 constituting the inner ring. 5个球974被组装于内圈968的斜面部即第一内侧引导部和保持圈970的斜面部分即第二内侧引导部以及外圈972的2个斜面部分即外侧引导部之间。 5 balls 974 are assembled to the coil portion between the inclined surface 970, i.e. the inner guide portion and the second outer guide portion i.e. two outer ramp portion 972 of the inner inclined surface portion 968, i.e., a first holding portion and the inner guide. 旋转杆齿972b设位于外圈972的外周部。 Rotating lever teeth 972b disposed on the outer peripheral portion of the outer ring 972. 保持架976被组装于内圈968 与保持圈970之间以有间隔地配置多个球974。 It is assembled to the holder 976 at intervals at a plurality of balls 974 arranged between the inner ring 968 and retaining ring 970. 保持架976采用不锈钢等金属板,通过对金属板的冲压加工,形成其外形形状。 Holder 976 using a metal such as stainless steel plate by press working of a metal plate, whose outer shape is formed. 在保持架976上设置了确定球974位置的5个半圆形的球定位部976g。 Holder 976 is provided on the ball with the positioning portion 976g 5 semicircular ball 974 to determine the location. 向每个球974周围注入润滑油。 Lubricating oil is injected into each ball 974 around.

用于传统自动上发条时钟的机芯中的球轴承具有包括外圈、内圈(含固定于内圈的保持圈)、多个球和保持架的结构。 Movement for a conventional self-winding clock in the frame structure having the ball bearing includes an outer ring, an inner ring (including retaining ring fixed to the inner race), and a plurality of balls held. 这些零件之间的接触(即滑动)状态分为[滚动接触]和[滑动接触]。 Contact between the parts (i.e., slide) into state [rolling contact] and the [sliding contact]. 即:外圈与球之间的接触为[滚动接触]。 That is: the contact between the outer ring and the ball is [rolling contact]. 内圈(和保持圈)与球之间的接触为[滑动接触]。 The contact between the inner (and retaining ring) for the ball [sliding contact]. 保持架与球之间的接触为[滑动接触]。 Maintaining contact between the cage and the ball is [in sliding contact]. 若将[滚动接触]和[滑动接触]作比较,则一般公知[滑动接触]比[滚动接触]的耐磨性差。 If [rolling contact] and the [sliding contact] for comparison, it is generally known [slide contact] is worse than [the rolling contact] abrasion resistance. 因此,对于己往的球轴承, 多依据保持架的磨损进展情况确定球轴承的寿命。 Thus, for ball bearings had to, according to maintain the multi-frame to determine the progress of the wear life of ball bearings. 为降低保持架上的这种磨损,向球上注入润滑油,则会发生以下问题。 To reduce this wear the cage, lubricant is injected into the ball, the following problem occurs.

第一,由于球轴承使用时的振动、冲击,有导致润滑油飞散的可能。 First, due to the use of ball bearing vibration, shock, may lead to scattering of a lubricant. 其结果,使润滑油黏附于不需润滑油的地方,从而引起各种零件性能的恶化。 As a result, the lubricating oil adhered to place without the lubricating oil, thereby causing deterioration of the performance of various parts. 例如,润滑油黏着在齿轮的齿面上,就会增大环列结构的粘性损失。 For example, the lubricating oil adhered on the surface of the gear teeth, the loss of the ring will increase the viscosity of the column structure. 此外,润滑油黏着在游丝上时,会导致时钟精度紊乱。 Further, the lubricating oil adhered on the spring, will cause clock accuracy disorders.

第二,由于润滑油的粘度随温度变化而变,会导致各种特性的下降。 Second, since the viscosity of the lubricating oil changes with temperature variations, result in deterioration in various properties. 例如,在低温状态下,润滑油的粘度增大,会使启动扭矩增大,这样可导致响应变差。 For example, at low temperatures, the viscosity of the lubricant is increased, it will increase the starting torque, which can lead to poor response. 另外,在高温状态下,润滑油的粘度降低,会使许容负荷减小和发生流油。 Further, at a high temperature, oil viscosity reduction, will reduce the allowable load and the oil flow occurs.

第三,由于润滑油的氧化和蒸发,会使注入的润滑油量减少和降低润滑性能。 Third, due to oxidation and evaporation of the lubricating oil, reducing the amount of lubricating oil injected will decrease and lubricity. 其结果,增大零件的磨损,或产生磨损粉末和粉末飞散,导致时钟性能下降。 As a result, increase wear part or wear powders and powder scattering, resulting in performance degradation clock.

第四,由于保持架的磨损,使润滑油中含有磨损粉末,增大润滑油的粘度,导致启动扭矩增大和响应变差。 Fourth, since the holder holding the wear, abrasion powder contained in the lubricating oil, the lubricating oil viscosity is increased, resulting in increased starting torque and response deterioration.

第五,由于诸如球等接收油注射的部分其可从球轴承外部看见的表面积相当可观,且润滑油的蒸发量多,因此挥发成份可能导致近旁的零件生锈,并可能诱发其他化学反应。 Fifth, since the injection of such oil ball receiving portion which is visible from the exterior of ball bearings considerable surface area and the amount of evaporation of the lubricant is large, and therefore may result in the vicinity of the volatile component parts to rust, and may induce other chemical reactions. 另外,由于外来的粉尘等容易侵入球引导面等的球轴承内部,其结果,有可能使球轴承寿命縮短。 Further, since the inner ball bearing ball guide surfaces easily penetrated external dust and the like, as a result, it is possible to shorten the life of the ball bearings.
