Abstract
A roller mounting assembly for a ground-engaging track system includes a frame, and a roller block coupled to the frame and including a shaft support surface extending through the roller block. The roller mounting assembly further includes a damper resiliently deformable, relative to the roller block, to dampen loads transmitted between the roller block and the frame. Embodiments of a roller block assembly and a damping shim assembly are also disclosed.

A roller mounting assembly for a ground-engaging track system comprising:
- a frame;
- a roller block coupled to the frame and including an upper surface and a lower surface each extending between a forward edge and a back edge of the roller block, an inboard side, and an outboard side;
- the roller block further including a shaft support surface extending through the roller block in an inboard-outboard direction and circumferentially around a center axis;
- a damper having a fore-aft length, an inboard-outboard width less than the fore-aft length, and a vertical thickness less than the inboard-outboard width;
- and
- the damper is resiliently deformable, relative to the roller block, to dampen loads transmitted between the roller block and the frame.
A roller block assembly for supporting a roller in a ground-engaging track system comprising:
- a roller block including an upper surface and a lower surface each extending between a forward edge and a back edge of the roller block, an inboard side, and an outboard side;
- the roller block further including a shaft support surface extending through the roller block in an inboard-outboard direction and circumferentially around a center axis, a first bolt bore extending through the roller block between the upper surface and the lower surface, and a second bolt bore extending through the roller block between the upper surface and the lower surface;
- a damper coupled to the roller block;
- and
- a first sleeve and a second sleeve within the first bolt bore and the second bolt bore, respectively, and each of the first sleeve and the second sleeve extending out of the respective first bolt bore or second bolt bore and at least partially through the damper.
A damping shim assembly for a roller in a ground-engaging track system comprising:
- a non-damping shim;
- a damping shim coupled to the non-damping shim and having a fore-aft length, an inboard-outboard width less than the fore-aft length, and a vertical thickness less than the inboard-outboard width;
- the damping shim further defining a longitudinal axis, and including a forward damper end, a back damper end, a first longitudinal edge extending continuously between the forward damper end and the back damper end, and a second longitudinal edge opposite to the first longitudinal edge and forming a locating cutout extending inwardly in a direction of the longitudinal axis;
- and
- the damping shim is resiliently deformable relative to the non-damping shim.
