  • Patent number: 10556283
    Abstract: A grommet is configured to be secured onto a wiring harness even when the diameter of the wiring harness shrinks. The grommet includes a tubular body having an inner wall defining a through-hole which is dimensioned to hold the wiring harness. The grommet includes a hole configured to receive a soldering tip of a soldering iron. The hole is open at the outer surface of the first body member and closed by the inner wall, wherein the inner wall serves as a temporary barrier which prevents the soldering tip of the soldering iron from coming into direct contact with the wiring harness. Thus, the soldering tip can melt a portion of the inner wall to adhere the grommet to the wiring harness without damaging the wiring harness.

A bush-like part for mounting on a shaft of the machine has an outer periphery provided with a recess for accommodating a ring. During operation of the machine, the ring, which is partially surrounded on its faces by circular ring-shaped walls of the recess, forms an axial gap with the circular, ring-shaped walls of the recess and a radial gap with the bottom of the recess. The ring is held by frictional contact with a rigid wall which surrounds it. To reduce wear on rings made of soft, flowable material, a second recess is formed in the rigid wall and surrounds the faces of the ring that project from the walls of the bush-like part. One of the lateral bounds of the second recess is formed by a tubular part detachably joined to the rigid wall.

An attachment bore passes laterally through the housing and is lined by a layer of the damping body. The attachment bore is disposed in the center of recessed surfaces of the hour-glass cross-section. An attachment pin passes through the attachment bore and the sleeve. The shift lever vibration isolator is freely slidable on the attachment pin, facilitated by a clearance between the attachment pin and the bore lining layer.

  • Patent number: 6925906
    Abstract: The vehicular shift lever has rubber bushes tightly fastened to the external surface of a lever axle and a cover pressed over the external side of the rubber bush. The shift lever includes: first and second rubber bushes fastened to the top and bottom of the lever axle with a preset interval therebetween; a plurality of protruders formed radially at the external circumferential surface of one or more rubber bushes; and a third rubber bush installed at the external side of the protruder with the internal and external sides thereof being attached to the external surface of the protruder and the internal surface of the cover, respectively. This reduces the amount of material required for the rubber bushes, and effectively absorbes vibration and decreases noise.

  • Patent number: 6840862
    Abstract: An adjustable coupler for in-line coupling of a motor drive shaft of an agricultural system with the square drive shaft of a gearbox, wherein the coupler has an adjustable clamping hub for securing around differing sizes of square drive shafts while maintaining coaxial alignment between the coupler, the square drive shaft and the motor drive shaft. The coupler is adjustable to fit different size square drive shafts, yet maintains symmetry about the center axis of the coupler, thereby reducing off-balance forces that could result in wear points and early fatigue. Contact surfaces between the coupler components are minimized to reduce the likelihood that contaminants can become entrapped between the components. The coupler is comprised of a round hub and a square hub, each attached to the opposite sides of a shock absorbing puck. The square hub is symmetrical about the axis of the puck and is formed of two axially sliding, opposing L-shaped brackets configured to clamp around the square end of a drive shaft.

    Abstract: A projecting portion 52 which becomes convex in radial direction is formed in a rubber elastic body 5 for connecting together an inner cylindrical body 3 mounted to a shaft portion 21a of a lower shift lever member 21 by external interfit and an outer cylindrical body 4 mounted to a cylindrical portion 22a of an upper shift lever member 22 by internal interfit. Formed in an inner peripheral surface of the outer cylindrical body 4 is a recessed portion 42 which becomes concave with clearances C1 and C2 of respective given amounts left between the recessed portion 42 and the projecting portion 52. This makes it possible to manufacture a shift lever bush 1 having a two-stage spring characteristic at low cost.

    Abstract: A pivot bushing for a suspension system has an inner metal and an outer metal with an elastomeric bushing disposed between the metals. The outer metal has one end which is partially closed by an inwardly curved portion and one end which is open. The assembly of the bushing is through the open end. Once assembled the open end is closed by placing a cover over the open end and crimping the cover to a flange formed at the open end. In another embodiment, the cover is inserted into the outer metal and the outer metal is crimped to secure the cover in place.

  • Patent number: 6125559
    Abstract: A plow blade is described which has first and second sections, e.g., a moldboard and a trip board, which are rotatable with respect to each other and maintained in a desired angular relationship with respect to each other via an elastic torsion joint. The elastic torsion joint includes an elongated inner member at least partially surrounded by an elongated outer sleeve. Resilient elastic cushioning wedges (e.g., elastomeric wedges) are situated between the inner member and outer sleeve in such a manner that rotation of the inner member with respect to the outer sleeve compresses the cushioning wedges and elastically resists rotation. The inner member and outer sleeve are respectively affixed to the moldboard and trip board (or vice versa) so that when the trip board strikes an obstruction and is biased with respect to the moldboard, the elastic torsion spring resiliently yields, and then causes the trip board to snap back to its original position with respect to the moldboard once the obstruction is removed.

  • Patent number: 6123481
    Abstract: An elastic shaft joint of the present invention comprises an elastic member, a slide sleeve and a stopper. The elastic member is composed of an elastic material such as rubber, elastomer etc and held on an inner peripheral surface of a cylindrical portion fixedly provided on the cylindrical member. The slide sleeve is made using a low-friction material such as a synthetic resin, an oil-impregnated metal etc, held on an inner peripheral surface of the elastic member and elastically pressed against an outer peripheral surface of the shaft by an elasticity of the elastic member. The stopper is provided between the shaft and the cylindrical member, permits the shaft and the cylindrical member to slightly displace in the axial and rotating directions, and hinders the displacement in the rotating direction beyond a predetermined angle enough to damage the elastic member and the slide sleeve.
