Abstract
A snubber for a machine includes a housing mounted on an implement, a shaft, a first member that has multiple helical splines that is coupled to the shaft. 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 received in the cylinder and dividing the cavity into a first chamber and a second chamber, a second member that has multiple helical splines and is coupled to the piston and, a hydraulic device. The helical splines of the first and second member engage with each other 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.
