Tolerance ring for torque transmission device

摘要

This tolerance ring, which is for a torque transmission device, preferably has a ring body that comprises an elastic plate and is roughly a hollow cylindrical shape having a pair of edges that extend in the axial direction. The ring body has: a plurality of protrusions that are arranged along the peripheral direction and preferably protrude in the radial direction; a first region having a number of the protrusions including the pair of protrusions adjacent to the pair of edges; and that is positioned at the diametrically opposite side from the first region. The pair of protrusions has the same rigidity as one of the protrusions of the second region.

1. A tolerance ring for torque transmission comprising:
a ring body made of an elastic plate and formed in a substantially hollow cylinder shape having a pair of edges comprising a first edge and a second edge, each of the first edge and the second edge extending in an axial direction; wherein the ring body includes a plurality of protrusions radially projecting outwardly and arranged in a circumferential direction, a first region, and a second region having a portion positioned diametrically opposed to the first region, the plurality of protrusions including a first plurality of protrusions positioned at the first region and having a first protrusion proximate the first edge and a second protrusion proximate the second edge, each of the first plurality of protrusions defining a first congruent shape, and a second plurality of protrusions positioned at the second region, including at the portion positioned diametrically opposed to the first region, the second plurality of protrusions including a first protrusion adjacent the first protrusion of the first plurality and a second protrusion adjacent the second protrusion of the first plurality, each of the second plurality of protrusions defining a second congruent shape, the second shape being larger than the first shape; wherein the first protrusion of the first plurality and the first protrusion of the second plurality are circumferentially consecutive and define a first spacing distance there between, and the second plurality of protrusions is defined by circumferentially consecutive protrusions between the first and second protrusions of the first plurality of protrusions and each pair of circumferentially consecutive second plurality of protrusions defining a second spacing distance there between, the first spacing distance is less than the second spacing distance, and the first plurality of protrusions and the second plurality of protrusions are aligned in the circumferential direction.
