The sheave (100) comprises a sheave axis (150) about which the sheave (100) rotates; a cylindrical sleeve (105); and a bearing (120a, 120b) centred on and arranged to rotate about the sheave axis (150). The cylindrical sleeve (105) includes an outer surface (110) including a groove (155) arranged to receive a belt; and an inner surface (115) defining a cylindrical cavity (122) centred on the sheave axis (150). The bearing (120a, 120b) includes an outer race (125a), an inner race (130a) and one or more rolling elements (135a) therebetween, wherein the outer race (125a) comprises a protrusion (140) arranged to hold the bearing (120a, 120b) within the cylindrical cavity (122) due to engagement between the protrusion (140) and the inner surface of the cylindrical sleeve (115).

摘要： A modular pulley assembly for a continuous belt conveyor can be assembly from a plurality of modular pulley disks that can be axially aligned and abut against each other to provide pulleys of differing lengths per demand. The modular pulley disks can be made from a non-metallic material such as a polymer and can manufactured by a suitable molding process. Making the modular pulley disks from non-metallic materials enables the disks to be formed with structural geometries such that the assembled pulley is structurally more rigid and can better distribute torsional loads and momentum from the belt to the support shaft.

摘要： A high torque sprocket includes a body defining an outer periphery and a hub section defining an inner surface for engaging a bushing. A continuous toothed structure is disposed on the outer periphery of the body, and a textile reinforcement embedded in the body adjacent the inner surface of the hub section. The body is formed of a castable polymer material. In some cases, one or two optional flanges are disposed on side(s) of the body immediately adjacent the continuous toothed structure, in some aspects, a textile reinforcement may be embedded in a surface of the flange(s) immediately adjacent the continuous toothed structure. In some aspects, ultra-high molecular weight polyethylene (UHMWPE) is incorporated into the castable polymer material mixture in an amount suitable to provide increased durability to the sprocket.

摘要： Construction is achieved by which it is possible definitely prevent the occurrence of creep between a pulley 2b and an outer ring 7f. Trapezoidal shaped concave sections are formed such that the angle of intersection θ between the inside surfaces 23 on both sides of each concave section 17a of knurling 19a of the outer ring 7f is within the range 45°≦θ≦120°.

摘要： There is provided a power transmission apparatus for a compressor used in an air conditioner for a vehicle. In the power transmission apparatus, a damper 20 is mounted to one side of a pulley 40 rotated by a driving power transmitted from an engine. In the damper 20, an elastic portion 21 is formed between an outer ring 23 and an inner ring 25, wherein a mounting flange 23a of the outer ring 23 is coupled to the pulley 40 and a mounting flange 25a of the inner ring 25 is coupled to a limiter 10. The limiter 10 has a plate shape and comprises: a middle portion 11 in a ring shape, an outside portion 12 in a ring shape around the edge of the middle portion 11, and a neck portion 13 connecting the middle portion 11 and the outside portion 12. Upon overload, the neck portion 13 is broken. The middle portion 11 of the limiter 10 is coupled to a hub 30, and the hub 30 penetrates the center of the inner ring 25 and is coupled to the limiter 10 between the damper 20 and the pulley 40.
