Description

Technical Field

[0001] The utility model relates to the technical field of end face cam structures, in particular to an end face cam used in conjunction with a VE type distribution pump of a diesel engine. Background Art

[0002] The end face cam is a cam whose contour curve is located at the end of a cylinder and rotates around its axis. Cylindrical cams and end face cams are collectively referred to as cylindrical cams. In a cylindrical cam mechanism, when the cam rotates, the follower moves in a plane parallel to the cam axis. Therefore, the relative movement of the cam and the follower causes spatial movement. The cylindrical cam mechanism belongs to the spatial cam mechanism. In the cylindrical cam mechanism, the follower can obtain a larger stroke through a cylindrical cam or end face cam with a small diameter.

[0003] The end face cam used in the existing diesel engine VE type distribution pump will wear out during use. When the wear reaches a certain extent, the end face cam used in the diesel engine VE type distribution pump needs to be disassembled and replaced. Replacing the entire end face cam used in the diesel engine VE type distribution pump will cause a waste of resources. Utility Model Content
