Abstract
A debris deflector includes an at least partially annular body defining a central axis, a radial direction, and a circumferential direction about the central axis. The at least partially annular body includes an outer radial extremity defining surface, an inner radial extremity defining surface, a first circumferential extremity defining surface, and a second circumferential extremity defining surface. A first deflection surface extends from the first circumferential extremity defining surface, and defines a first surface normal that points away from the central axis.
Claims18
A debris deflector for preventing the fouling of a final drive, the debris deflector comprising:
- an at least partially annular body defining a central axis, a radial direction, and a circumferential direction about the central axis, the at least partially annular body including
- an outer radial extremity defining surface;
- an inner radial extremity defining surface;
- a first circumferential extremity defining surface;
- and
- a second circumferential extremity defining surface;
- wherein the first and second circumferential extremity defining surfaces each include a first deflection surface having a triangular shape and a second deflection surface, the first and the second deflection surfaces being non-parallel.
A debris deflector subassembly for preventing the fouling of a final drive, the debris deflector subassembly comprising:
- a bolt-on mounting ring including
- an at least partially ringlike body defining
- an axis of rotation, a radial direction, and a circumferential direction about the axis of rotation, the at least partially ringlike body including
- an outer circumferential extending surface;
- an inner circumferential extending surface;
- a first circumferential end defining surface;
- a second circumferential end defining surface;
- a front surface;
- and
- a rear surface;
- wherein the at least partially ringlike body defines a first fastener receiving counterbore on the front surface that is disposed circumferentially adjacent the first circumferential end defining surface, and a first fastener straight thru-hole that is spaced circumferentially from the first fastener receiving counterbore a predetermined angle about the axis of rotation ranging from 50.0 degrees to 70.0 degrees.
A final drive for use with a machine, the final drive comprising:
- a fixed interior hub;
- a rotating exterior hub;
- a sprocket attached to the rotating exterior hub;
- a shaft housing extending between the fixed interior hub toward the rotating exterior hub;
- a gear housing extending between the shaft housing and the rotating exterior hub;
- and
- a debris deflector assembly attached to the fixed interior hub, the debris deflector assembly including
- a pair of bolt-on mounting rings, and a pair of debris deflectors attached to the pair of bolt-on mounting rings, the pair of debris deflectors each including first and second non-parallel deflection surfaces provided at circumferential ends.
