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, a rolling axis of each roller is made to be in a range larger than an angle of 5° and smaller than an angle of 20° with respect to a rotational axis of the rotor, and the rolling axis of each roller is made to be in a range larger than an angle of 25° and smaller than an angle 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.

Abstract: 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.

Abstract: A mechanism of a simple structure, in which always stable and discretionary frictional resistance can be produced even when the speed of rotary movements or rectilinear movements of the subject structure changes and, moreover, the magnitude of the frictional force can be easily controlled by changing the magnitude of a load. Namely, when a rotary member 1 is rotated while a load toward the axial direction is being applied, numerous rollers 2 make rolling motions in contact with the rotary member 1 and a passive member 3. The rollers 2 make rolling motions along a track of rotation of the rotary member 1. The rollers 2 are restrained to roll toward a direction being inclined by a prescribed angle by a cage 4. This results in producing a frictional force in proportion to the magnitude of the load being applied to the axial direction between the rollers 2 and the rotary member 1 nd between the rollers 2 and the passive member 3.

Abstract: 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.

Abstract: When second rotating bodies are made eccentric, the second rotating bodies move straight in the radial direction along first rotating bodies. Therefore, the cyclically changing angular velocity of the second rotating body changes so that the side on which the angular velocity is higher than the angular velocity of the input-side rotating body and the side on which the angular velocity is lower are symmetrical to each other. Also, on both of the side on which the angular velocity is higher and the side on which it is lower, the acceleration side and the deceleration side change symmetrically to each other. On the other hand, the angular velocity of the second rotating body such that the movement direction with respect to the first rotating body is shifted 180 degrees with each other with the input-side rotating body being the center changes symmetrically with respect to the angular velocity of the input-side rotating body.

Abstract: The present invention provides a rotary compressor capable of significantly reducing the loss attributable to mechanical friction. Since an outer rotor 2 is connected via connecting plates 4 to an inner rotor 3, when the outer rotor 2 is rotated by external rotational force, the inner rotor 3 can rotate together with the outer rotor 2 in the same direction. At that time, the rotors 2 and 3 rotate at positions offset relative to each other so that partition pieces 2d on the outer rotor 2 perform circular movement within partition grooves 3b in the inner rotor 3 while turning the connecting plates 4. Thus, the rotors 2 and 3 rotate together, with at least two partition pieces 2d turning all the time along the inner surfaces of the associated partition grooves 3b in a non-contact manner, so that a fluid from an inflow port 1d flows into a space between the rotors 2 and 3 partitioned by the partition pieces 2d and the partition grooves 3b, the fluid being discharged through an outflow port 1e.

Abstract: When an input shaft 6 is rotated by an external driving force, the resultant rotational force of the input shaft 6 is transmitted to an offset housing 21 of which rotational force in turn is transmitted to variable rings 39. If, at that time, angular volocities of the variable rings 39 are periodically varied relative to the angular velocity of the offset housing 21, the periodically varying angular velocities of the variable rings 39 are corrected to be substantially constant in a predetermined phase range, allowing only rotational forces having corrected angular velocities to be fetched from the variable rings 39 for transmission to an output shaft 7. Thus, by arbitrarily varying the angular velocities of the variable rings 39 relative to the angular velocity of the offset housing 21, the rotational speed of the output shaft 7 is steplessly varied relative to the rotational speed of the input shaft 7.

Abstract: The present invention provides a differential gear which is capable of constructing an axle supporting structure at a low cost and obtaining a differential limiting effect without adding a special mechanism. In the present invention, each axle is coupled to the main body of the differential gear by regulating movement of each axle in the insertion direction and the counter-insertion direction by both a regulating member engaging with each axle and a regulating member interposed between the end surfaces of the axles. In this case, differential motion is achieved by both grooves provided in a pair of rotating bodies which rotates integrally with drive shafts and a plurality of balls 5 which roll along the grooves, and the differential motion is limited by the reactive force generated between each groove and the rolling bodies. Thus, a differential limiting effect is obtainable without adding a special mechanism.

Abstract: 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.

Abstract: A method of applying a coating material to two surfaces of a plate includes the steps of applying the coating material to the two surfaces simultaneously such that holding areas in the absence of the coating material are provided on the two surfaces in proximity of side ends of the plate with respect to a travel direction of the plate, and conveying the plate by holding the holding areas.

Abstract: A differential gear is capable of differentially setting magnitudes of differential limiting forces depending on directions of rotational force transmission. A rotational force of the input-side rotary element is transmitted by way of rolling elements and grooves to the rotary elements. The rolling elements roll along grooves of the rotary elements 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.

The insulating spacer according to the present invention can lessen the concentration of electric fields in the boundary areas between the shield electrode and the insulating member with the result that reliability is improved and service life is lengthened.

Abstract: 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.

Abstract: This invention provides a differential gear that permits a sure differential limitation effect to be obtained with a simple structure and that is both compact in size and low in price. That is, when a rotational difference occurs on a pair of output-side rotary bodies arranged in opposite form to each other on the shaft center of an input-side rotary body, 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 and numerous balls 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.
