475178000 | Circumferentially spaced connector pins | 9 |
20080242465 | Transmission for vehicle steering apparatus - A vehicle steering apparatus having a drive ( | 10-02-2008 |
20080305909 | REDUCTION GEAR - A reduction gear includes a reduction mechanism, which includes: an external gear eccentrically rotatable about an input shaft; an internal gear internally meshing with the external gear and having a small number of difference between the teeth of the internal gear and the external gear; a disk for extracting only a rotational component of the external gear; an output shaft; and gears for transmitting the rotational component of the external gear from the disk to the output shaft. The disk, the gears and the output shaft are aligned in a direction perpendicular to an axial direction of the input shaft. | 12-11-2008 |
20090156347 | Power Transmission Device - An object is to provide a compact power transmission device which comprises a small number of parts and is compact in size, and which can transmit the rotation of a rotary shaft to a wheel with a high reduction ratio. | 06-18-2009 |
20090270216 | Apparatus and method for improving radial stresses in a gear transmission mounting - There is provided a pin and mounting assembly for supporting a gear of an epicyclic or parallel shaft transmission. The pin and mounting assembly comprises: a mounting ( | 10-29-2009 |
20100292040 | REDUCTION GEAR - The reduction gear includes a plurality of first and second rollers that are disposed so as to directly come into rolling contact with the outer peripheries of first and second eccentric bodies; first and second retainers that maintain gaps between the first and second rollers in the circumferential direction of the first and second eccentric bodies; and first and second guide bodies of which the movement in the axial direction is restricted and which restrict the movement of the first and second rollers in the axial direction by coming into direct contact with ends of the first and second rollers. | 11-18-2010 |
20120258835 | REDUCTION GEAR - A reduction gear includes an outer circumference internally toothed gear having first teeth; and an inner circumference externally toothed gear having a second teeth. The reduction gear relatively rotates while the first teeth and the second teeth engage each other. At least one of the first and second teeth has an elastic structure inside the tooth so that the tooth is elastically deformable. | 10-11-2012 |
20130178322 | SPEED REDUCTION MECHANISM, AND MOTOR TORQUE TRANSMISSION DEVICE INCLUDING THE SAME - When an outer ring is fitted to an inner periphery of an input member, which defines a center hole, and an inner ring is fitted to an eccentric portion with clearances in a reduction-transmission mechanism, in a state where tooth tips of the input member contact bottomlands of a rotation force applying member on a line perpendicular to a second axis and a fourth axis, a size between the second axis and a third axis is set to a size that is smaller than or equal to half of a size obtained by adding a diameter difference between an outside diameter of a ball bearing and an inside diameter of the input member, which defines the center hole, a diameter difference between an inside diameter of the ball bearing and an outside diameter of the eccentric portion and an operating clearance of the ball bearing. | 07-11-2013 |
20130225354 | PLANETARY GEAR REDUCER - In a planetary gear device, a first side plate as carrier is formed to a disc plate shape and secures thereto pins to protrude the pins from one end surface in an axial direction. The outside diameter of the first side plate is formed to be a small diameter on one side in the axial direction and a large diameter on the other side in the axial direction. The first side plate is provided with press-fitting hole portions with the pins press-fitted thereinto and small-diameter side concavities that are formed on the press-fitting hole portions on one side in the axial direction, that open to one end surface in the axial direction of the first side plate and that have internal surfaces being out of contact with the pins at at least parts thereof. | 08-29-2013 |
475179000 | Roller bearing surrounds pin | 1 |
20100179013 | CENTER CRANK ECCENTRICALLY OSCILLATING SPEED REDUCER - The present invention provides a center crank eccentrically oscillating speed reducer enabled to increase the available cross-sectional area of a hollow hole, while the generation of large noises is suppressed, as compared with the conventional center crank eccentrically oscillating speed reducer. | 07-15-2010 |
