Abstract
A snubber for a machine includes a housing, a shaft and a pinion that is coupled to the shaft. The housing is mounted on an implement of the machine. The shaft is rotatably received within the housing and operatively coupled to a movable component of the implement. The snubber also includes a cylinder defining a cavity, a piston slidably received within the cylinder, a rack coupled to the piston, and a hydraulic device. The cylinder is at least partly disposed within the housing. The piston divides the cavity of the cylinder into a first chamber and a second chamber. The rack engages with the pinion to convert a rotation of the shaft into a linear movement of the piston. The hydraulic device is in fluid communication with the cavity and controls a flow of fluid between the first chamber and the second chamber to oppose rotation of the shaft.
