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 ( alpha 1) of 5 DEG and smaller than an angle ( alpha 1) of 20 DEG 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 ( beta 1) of 25 DEG and smaller than an angle ( beta 1) of 90 DEG 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： A differential gear which can always obtain a stable differential limiting force even in low-speed rotation. A plurality of rollers are provided between a raceway surface integrally rotating with an input-side rotating body and a raceway surface integrally rotating with an output-side rotating body. A tilt angle of the axes of rolling of the rollers with respect to the axis of rotation of the raceway surfaces is made smaller than 20.degree., and a tilt angle of the axes of rolling of the rollers with respect to a plane including the axis of rotation of the raceway surfaces is made larger than 25.degree. and smaller than 90.degree.. Thereby, a stable frictional force can be produced between the rollers and the raceway surfaces, and a differential limiting force without producing a stick-slip even in low-speed rotation can be obtained.

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： A small, inexpensive, comparatively simple differential gear, having reliable revolution difference restricting effects includes a rotary casing and a retainer having a common rotation axis. Torque is transmitted to a groove of a pair of rotary members via rolling elements so the rotary members rotate with the casing. When a revolution difference occurs between the rotary members, rolling elements retained in guide slots of the retainer roll along the grooves of the rotary members so there is reciprocal movement within the range of the guide slots. When a force causing a revolution difference between the rotary members is applied from the side of only one of the rotary members, the resulting reaction force restricts the revolution difference between the pair of rotary members. This is because the rolling elements which come to the following side when the revolution difference exists trail the groove which comes to the leading side when a revolution difference occurs in response to their own movements. Reliable torque-sensitive revolution difference restricting effects are provided without a special mechanism to obtain a revolution difference restricting effect.

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 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 relates to a friction clutch in which the wear in the sliding state can be reduced and an automatic transmission of an automobile using the friction clutch and a non-stage transmission of an automobile and a power distribution device of an automobile and a power transmission device of a motorcycle. That is, according to the present invention, in a configuration of making a pair of clutch members opposite to each other in a radial direction with a plurality of rollers held between them, an angle of a turning axis of each roller relative to the rotation axis of a clutch member is made more than 10.degree. and less than 20.degree., and in the meantime, the angle of the turning axis of each roller relative to the plane including the rotation axis of the clutch member is made more than 25.degree. and less than 90.degree., so that a stable frictional force may be generated at all times. In this case, when a load in an axial direction is added to the clutch member, each roller generates sliding friction while turning, and therefore, a wear is extremely smaller than that of a structure of bringing the respective fellow clutch plates into surface contact with each other like a multiple disk clutch.

摘要： A differential gear which can always obtain a stable differential limiting force even in low-speed rotation. A plurality of rollers (6) are provided between a raceway surface (5B) integrally rotating with an input-side rotating body (1) and a raceway surface (3B) integrally rotating with an output-side rotating body (3). A tilt angle of the axes of rolling of the rollers (6) with respect to the axis of rotation of the raceway (3A,5A) surfaces is made smaller than 20°, and a tilt angle of the axes of rolling of the rollers with respect to a plane including the axis of rotation of the raceway surfaces (3A,5A) is made larger than 25° and smaller than 90°. Thereby, a stable frictional force can be produced between the rollers and the raceway surfaces, and a differential limiting force without producing a stick-slip even in low-speed rotation can be obtained.
