Abstract
A drive sprocket comprising a plurality of teeth for meshing with a drive member to transmit rotary motion, the drive member including a plurality of engagement pockets engaging the teeth of the drive sprocket, wherein each tooth has a tooth profile defined by a first side comprising a first engagement surface and an opposite second side comprising a second engagement surface, which engagement surfaces are configured such that when driven, a tooth meshes to the engagement pocket at a first contact location on the first engagement surface and also at a second contact location on the second engagement surface, wherein the first contact location is radially offset from the second contact location.
Claims17
A drive sprocket comprising a plurality of integrally formed teeth for meshing with a drive member to transmit rotary motion, the drive member including a plurality of engagement pockets engaging the teeth of the drive sprocket, wherein each tooth has a tooth profile defined by a first side comprising a first engagement surface and an opposite second side comprising a second engagement surface, which engagement surfaces are configured such that when driven, a tooth meshes to the engagement pocket at a first contact location on the first engagement surface and also at a second contact location on the second engagement surface, wherein the first contact location is radially offset from the second contact location, wherein each tooth has a front face and a back face, the shape of which faces being defined by the first and second sides, wherein the shape of each face is symmetrical about a radial axis of the tooth.
A transmission system comprising:
- a drive sprocket;
- and
- a drive member, which drive member is adapted to mesh with the drive sprocket,
- wherein the drive sprocket comprises a plurality of integrally formed teeth for meshing with the drive member to transmit rotary motion,
- wherein the drive member includes a plurality of engagement pockets engaging the teeth of the drive sprocket,
- wherein each tooth has a tooth profile defined by a first side comprising a first engagement surface and an opposite second side comprising a second engagement surface, which engagement surfaces are configured such that when driven, a tooth meshes to the engagement pocket at a first contact location on the first engagement surface and also at a second contact location on the second engagement surface,
- wherein the first contact location is radially offset from the second contact location,
- wherein each tooth has a front face and a back face, the shape of which faces being defined by the first and second sides, and
- wherein the shape of each face is symmetrical about a radial axis of the tooth.
