摘要： This invention intends to provide a smaller sized and low priced differential gear of a comparatively simple structure wherefrom reliable revolution difference restricting effects can be obtained. Namely, when a casing and a retainer are rotated around their axis, such torque is transmit to the groove of each rotary member via the rolling elements and the pair of rotary members rotate together with the casing. When a revolution difference occurs between said pair of rotary members, rolling elements retained in the guide slots of said retainer rolls along the grooves of said pair of rotary members to make reciprocal movement within the range of said guide slots. At this time, when a force which causes revolution difference between said pair of rotary members is applied from the side of only one of said pair of rotary members, since the rolling elements which come to the following side when revolution difference is occurring work to let trail the groove which comes to the leading side when revolution difference is occurring to their own movements, the reaction force occurring here works as a resistance to restrict the revolution difference between said pair of rotary members. This invention can therefore provide reliable torque-sensitive revolution difference restricting effects without need for addition of a special mechanism to obtain the revolution difference restricting effect.

摘要： The present invention provides a friction resistance generator which can more effectively generate a stable friction resistance. More specifically, according to the present invention, in the configuration where a rotor and a passive member face each other in a radial direction through a plurality of rollers (2), a rolling axis (2a) of each roller (2) is made to be in a range larger than an angle (α1) of 5° and smaller than an angle (α1) of 20° with respect to a rotational axis (1b) of the rotor, and the rolling axis (2a) of each roller (2) is made to be in a range larger than an angle (β1) of 25° and smaller than an angle (β1) of 90° with respect to a plane including the rotational axis of the rotor. Thereby it is possible to always generate an effective and stable frictional force.

摘要： The present invention provides a differential gear capable of constantly ensuring a stable differential motion restricting force even in the case of a low rotational speed. In the present invention, when there occurs a difference in rotational speed between output side rotary elements, rollers are allowed to roll while being in contact with the confronting faces of the input side and output side rotary elements. The rollers move along rotational trajectories of the output side rotary elements while being restricted by a holder element from rolling toward the direction inclined by a predetermined angle relative to the rotational trajectories of the output side rotary elements. Thus, there occurs a frictional force between the rollers and the contact faces therewith, which results in a resistance to restrict the differential motion, At that time, the rollers generate a sliding friction in the course of rolling, thereby always ensuring a stable frictional force based on a dynamic friction even at a low rotational speed.

摘要： The present invention aims at realizing with a simple structure a differential gear capable of arbitrarily producing a difference in speed of rotation between output side rotary members. When a difference in speed of rotation occurs between drive shafts 3 and 4, if clutches 12 and 17 are disconnected, a first input side sun gear 8 and a first output side sun gear 9 are allowed to rotate at arbitrary speed ratios independently of each other due to the rotation and the revolution of first planetary gears 10, besides a second input side sun gear 13 and a second output side sun gear 14 are allowed to rotate at arbitrary speed ratios independently of each other due to the rotation and the revolution of second planetary gears 15. When the first clutch 12 for example is brought into connection, the revolution of the first planetary gears 10 is controlled. Thus, by setting appropriately the gear ratio between the sun gears 8, 9 and gears 10a, 10b of the first planetary gear 10, the drive shaft 3 on one hand is allowed to rotate faster than the drive shaft 4 on the other.

摘要： The present invention provides a differential gear capable of differentially setting magnitudes of differential limiting forces depending on directions of rotational force transmission. In the present invention, a rotational force of the input-side rotary element (1) is transmitted by way of rolling elements (5) and grooves (3b) to the rotary elements (3). The rolling elements (5) roll along grooves (3b) of the rotary elements (3) while reciprocating within elongated holes of the retainer element, thereby permitting the difference in speeds of rotation between the rotary elements. The differential motions of the rotary elements are limited by axial reaction forces generated between the rotary elements and the grooves. At that time, if the directions of the rotational force transmission between the input-side rotary element and the rotary elements differ from each other, then the magnitudes of the axial reaction forces generated between the rotary elements and the grooves will also be different from each other. Hence, differential limiting forces are generated which differ in magnitude from one another depending on the directions of transmission of rotational forces.

摘要： This invention provides a differential gear that, when a rotational difference occurs on a pair of output-side rotary bodies (17) arranged in opposite form to each other on the shaft center of an input-side rotary body (1), a differential rotation of each output-side rotary body is achieved by interconnecting the rotary motion of each output-side rotary body by means of numerous grooves (10a) and numerous balls (6) fitted to these grooves. At this time, when the force necessary to cause a rotational difference is given to each output-side rotary body only from one output-side rotary body, the balls or grooves of the driven side at differential rotation cause the grooves or balls of the driving side to follow their own motion on the other output-side rotary body. Consequently, the reaction force caused at this time acts as a resistance to limit the differential rotation of each output-side rotary body. Accordingly, this invention permits a very stable differential limitation effect of torque sensitizing type to be obtained without requiring any special mechanism for this purpose.
