Abstract
An assembly (10) of a tapered bushing (14) and a toothed wheel (12), having a preferred direction of rotation. The assembly (10) having on each face (22, 24) a hole or set of holes H1, H2 containing surfaces which interact with a threaded rod (26) for mating and/or separating of the assembly (10) form either face (22, 24). In a preferred embodiment of the invention, the assembly (10) will have two mating holes and one separation hole on each face (22, 24) of the assembly (10). This assembly (10) allows ease of mating and/or separating the assembly when access is limited to only one face of the assembly.
Claims8
An assembly (10) of a toothed wheel (12), a tapered bushing(l4), and a threaded rod (26);
- the toothed wheel (12), having a preferred direction of rotation about an axis, and having a tapered hole (16) forming at least one tapered surface (18) in the wheel (12) and forming a first opening (W1) and a second opening (W2), the first opening being larger than the second opening;
- the tapered bushing (14) having a least one tapered surface (20), the tapered surface (20) being capable of a mating relationship with the wheel tapered surface (18);
- the assembly (10) having a first face (22) and a second face (24) spaced apart from one another along an axis and when the tapered surfaces (18, 20) are in a mating relationship, the first opening (W1) of the wheel tapered hole (16) is in proximity to the first face (22) of the assembly (10) and a second opening (W2) of the wheel tapered hole (16) is in proximity to second face (24) of the assembly (10);
- the assembly (10) having at least one first hole (H1) for receiving the threaded rod (26), the hole (H1) extending at least partially along the mating surfaces from the first face (22) of the assembly (10) toward the second face (24) of the assembly (10), the hole (H1) being formed in part by a groove (28) located in the toothed wheel (12) and in part by a groove (30) located in the bushing (14) wherein the wheel groove (28) has a length as measured along the mating surfaces at least as great as the length of the bushing groove (30);
- the assembly (10) being characterized by:
- the assembly (10) having at least one second hole (H2) for receiving the threaded rod (26), the hole (H2) extending at least partially along the mating surfaces from the second face (24) of the assembly (10) toward the first face (22) of the assembly (10), the hole (H2) being formed in part by a groove (32) located in the toothed wheel (12) and in part by a groove (34) located in the bushing (14), wherein the bushing groove (34) has a length as measured along the mating surfaces at least as great as the length of the wheel groove (32) and
- wherein the wheel groove (28) partially forming the first hole (H1) and the bushing groove (34) partially forming the second hole (H2) are identical in configuration and the bushing groove (30) partially forming the first hole (H1) and the bushing groove (32) partially forming the second hole (H2) are identical in configuration.
