摘要： A preload applying mechanism includes a preload adjusting plug that is screwed to an inner peripheral surface of a housing body, and is rotationally moved; and a needle bearing and a plate that are arranged between an output shaft and a Z1 gear. In a shoulder of the output shaft, the Z1 gear is supported by the needle bearing and the annular plate for a rolling surface of the needle bearing so that the Z1 gear is rotatable. As the preload adjusting plug presses the output shaft, the shoulder of the output shaft presses the plate, the needle bearing, and the Z1 gear toward the center bearing in the axial direction. Thus, a preload is applied to the bearing gear.

摘要： A pin for guiding a gear has a substantially cylindrical outer surface section, wherein the outer surface section comprises a substantially cylindrical rolling surface section, which is aligned and formed so as to make possible the guiding of the gear. The outer surface section further has a groove, which is formed so as to accommodate a retaining ring, wherein the groove is disposed with respect to the rolling surface section so as to make possible a guiding, directly or indirectly via the retaining ring, of a rolling-element assembly along the axial direction of the pin. In this way it is possible to provide a guiding of a gear wherein a small tolerance chain is implemented with respect to the axial position.

摘要： A gear arrangement for a planetary gearbox includes a planet carrier, a planet pin, a planet gear, bearing means located between the planet pin and the planet gear, the bearing means including a bearing ring, a retainer secured to the planet carrier by one or more bolts, and one or more shims located between the retainer and the planet pin. The planet pin is hollow and is in fluid communication with an inside surface of the bearing ring and with an inlet. This means that a fluid forced via the inlet and the hollow planet pin applies a radial force to the bearing ring, reducing the contact friction between the bearing ring and the planet pin and allowing an axial position of the planet pin to be adjusted to provide a correct preloading to the bearing means. This means that the bearing can be pre-set, in-situ using hydraulic actuator and oil injection.
摘要翻译：用于行星齿轮箱的齿轮装置包括行星架，行星销，行星齿轮，位于行星销和行星齿轮之间的轴承装置，轴承装置包括一个轴承环，一个通过一个或者更多的螺栓，以及位于保持器和行星销之间的一个或多个垫片。行星销是中空的，并且与轴承环的内表面和入口流体连通。这意味着通过入口和空心行星销强制的流体向轴承环施加径向力，减小了轴承环和行星销之间的接触摩擦，并允许行星销的轴向位置被调节以提供正确预载到轴承装置上。这意味着轴承可以使用液压执行器和注油原位预先设定。

摘要： A method for adjusting the meshing position of a hypoid gear having a first gear, and a second gear meshing with the first gear and transmitting the rotary motion thereof in the direction different from the extending direction of the axis of rotation of the first gear. The method for adjusting the meshing position comprises; a) a step for displacing the second gear a plurality of times along the axial direction of rotation while meshing with the first gear, b) a step for measuring the transmission error at each displacement position and plotting the relation of the displacement distance of the second gear and the measured transmission error, c) a step for evaluating the virtual transmission error between the measured transmission errors from the measured transmission error, d) a step for subtracting the measured transmission error and the virtual transmission error from a maximum allowable transmission error to determine the difference, e) a step for determining the area of a part surrounded by the difference and the maximum allowable transmission error by integrating the difference with the displacement distance of the second gear, and f) a step for dividing the part at a predetermined area ratio and setting a point where the division line intersects the displacement distance of the second gear at the meshing position of the second gear.
