The invention relates to an assembly comprising a bushing with a center line L, having an inner sleeve with a mounting bore, an outer sleeve and an elastomeric spring member extending along a height H along the center line L. In one embodiment, the outer surface of the inner sleeve, the spring member and the inner surface of the outer sleeve are on each side of the center line L substantially parallel. On at least one side of the longitudinal center line L, the outer surface of the inner sleeve, the spring member and the inner surface of the outer sleeve extend at an angle to the center line L. An outer surface of the outer sleeve is substantially parallel to the center line L along the height H. Another embodiment of an assembly according to the invention comprises a bushing with a mounting bore that extends at an angle to the center line L. The bushing according to the invention is compact, can be easily manufactured and assembled, take up a high load and can be adjusted to the direction along which forces act on the bushing.

The bushing includes an outer cylinder, an inner cylinder, and an elastic body therebetween. The outer cylinder has a central recess portion formed in a curved shape. The inner cylinder has a central convex portion being formed in a curved shape. A distance between a vertex of the central recess portion and the vertex of the central convex portion is smaller than a distance between a point other than the vertex of the central recess portion and a point at which a straight line extending from the point other than the vertex of the central recess portion to an intersection point of the perpendicular line and the axis of the inner cylinder intersects the central convex portion.

A rubber-metal bush bearing, in particular a control arm bearing for a motor vehicle wheel suspension, including a metal inner part, an elastomer body arranged radially relative to the inner part and a metal outer bush, wherein the elastomer body is fixed to the inner part and to the outer bush in material-bonded relationship and wherein the outer bush is for fixing in an associated bearing eye of an arm and the inner part has at both sides in terminal relationship a respective flat flange portion for fixing to a component. The inner part is an extruded hollow-chamber profile member which is cut to length and which at both longitudinal ends is transformed in terminal relationship into the respective flat flange portion in such a way that oppositely disposed wall portions of the hollow-chamber profile member are brought into mutual surface contact.

Provided is a sliding bushing in which sliding of an inner shaft member with respect to a main rubber elastic body is allowed. The inner shaft member includes a bulge part provided midway in an axial direction. A braided cloth-like sliding liner is arranged between the inner shaft member and the main rubber elastic body so as to be non-adhesive and slidable with respect to the inner shaft member. In a portion of the sliding liner arranged on an outer periphery with respect to a large diameter part of the bulge part of the inner shaft member, a coarse part is provided of coarser braid mesh than a portion of the sliding liner arranged on an outer periphery with respect to a small diameter part on both axial sides of the large diameter part.

A tunable mass damping device, including a connecting, a weighted assembly, and a top connecting assembly connecting an upper end of the connecting rod with a tower beam of a tower and including an anti-rotation mechanism. The anti-rotation mechanism includes: a laterally extending fixing plate fixedly connected with the tower beam through a longitudinally extending supporting member; a laterally extending first movable plate arranged under the fixing plate and fixedly connected with the upper end of the connecting rod; and two connecting shafts spaced apart from each other. Each of the connecting shafts has a lower end fixedly connected to the first movable plate, and an upper end inserted into the fixing plate and connected therewith through a connecting head. The connecting head includes an intermediate elastic layer arranged between inner and outer sleeves of the connecting head.

A drive transmission device according to one embodiment of the disclosure includes: an arm having a motor that generates a rotational force; a speed reducer that is provided in the arm and has a carrier for decelerating rotation of the motor and outputting the decelerated rotation; a bucket fixed to the carrier by a reamer bolt, the reamer bolt being inserted in a bracket through hole formed in the bucket; and a resin bush provided between an internal surface of the bracket through hole and an external lateral surface of the reamer bolt. The mechanical strength of the resin bush is lower than the mechanical strength of the bucket and the mechanical strength of the reamer bolt.

According to one embodiment, a bearing features an elastomeric portion having an opening therethrough, a member disposed within the opening of the elastomeric portion, and a separation feature disposed between the member and the elastomeric portion. The member comprises a conical body portion arranged such that an interior diameter of the conical body portion is smaller than an exterior diameter of the conical body portion. The separation feature prevents contact between the member and the elastomeric portion.
