摘要： In a parallel-axis differential, pocket pairs are formed in an inner periphery of a housing and planetary gear pairs are rotatably received in the pocket pairs, respectively. With outer peripheral surfaces of the planetary gears (i.e., top faces of helical teeth) being in contact with inner peripheral surfaces of the pockets, the planetary gears are rotated relative to the housing. End portions of the helical teeth located on opposite end portions of each planetary gear are gradually reduced in height toward ends of the planetary gear. By this, top faces of end portions of those helical teeth are slightly convexly curved. The top faces of the end portions of those helical teeth are served as contact surfaces which are brought into contact with the inner peripheral surfaces of the pockets when the planetary gears are slightly inclined.
摘要翻译：在平行轴差速器中，腔体对形成在壳体的内周中，并且行星齿轮对分别可旋转地容纳在口袋对中。由于行星齿轮的外周表面（即螺旋齿的顶面）与凹穴的内周表面接触，所以行星齿轮相对于壳体旋转。位于每个行星齿轮的相对端部上的螺旋齿的端部朝行星齿轮的端部逐渐减小高度。由此，这些螺旋齿的端部的顶面略微凸出地弯曲。这些螺旋齿的端部的顶面用作接触表面，当行星齿轮稍微倾斜时，它们与凹穴的内周表面接触。

摘要： Arranged within a differential gear case are first and second side gears rotating together with first and second output shafts, respectively; first and second differential gears engaged with one of the first and second side gears and rotatably supported within cylindrical holes, respectively, so as to be partially engaged with each other to move circularly together with the differential gear case; and a viscous coupling capable of transmitting, between a hub rotating together with the output shaft and a housing, a torque in response to the difference in the speed. The outer periphery of the housing is provided with a cam surface to be engaged, in the direction of rotation, with the first and second differential gears to press and bias the first and second differential gears against the inner cylindrical surfaces of the cylindrical holes.
摘要翻译：在差速齿轮箱内布置的是分别与第一和第二输出轴一起旋转的第一和第二侧齿轮; 第一和第二差速齿轮分别与第一和第二侧齿轮中的一个啮合，并分别可旋转地支撑在圆柱形孔内，以便彼此部分地接合以与差速齿轮箱一起移动; 以及能够在与输出轴一起旋转的轮毂和壳体之间传递响应于速度差的转矩的粘性联轴器。壳体的外周设置有凸轮表面，该凸轮面在旋转方向上与第一和第二差速齿轮啮合，以将第一和第二差动齿轮压靠在圆柱形孔的内圆柱形表面上。

摘要： A worm gear type differential mechanism has a bias ratio equalization mechanism disposed between the casing and the worm gears. The bias ratio equalization mechanism includes frictional members disposed between axially opposite transverse faces of the casing and each of the worm gears, and each of the frictional materials has frictional faces which create the same friction force per unit of thrust force applied thereagainst. The frictional materials fix the worm gear axially to the casing.

摘要： A differential structure includes a differential case defining a differential gear chamber. The differential gearing is located in the gear chamber and includes a pair of side gears and pinion gears meshing with the side gears and which pinion gears are rotatable with the case. The side gears are output gears and a pair of output drives are connected with the respective side gears for driving respective loads. A lockup clutch mechanism is associated with one of the side gears for retarding rotation of the side gear relative to the case in response to a predetermined degree of relative rotation therebetween. The differential is constructed to deactivate the lockup clutch upon a predetermined torque being applied to the differential due to windup of the output drives.
