Description

Technical Field

[0001] The utility model relates to the technical field of camshaft gear equipment, in particular to a camshaft gear which is convenient for installation and positioning. Background Art

[0002] Camshaft gear is a common accessory used in automobile engines. Camshaft gear usually refers to the gear directly connected to one end of the camshaft. It meshes with the timing gear on one end of the crankshaft, so that the camshaft can rotate with the crankshaft at a transmission ratio of 2 to 1, thereby pressing the valve on time to ensure the intake and ventilation of the four strokes of the engine. During the operation of the gear, the gear teeth are prone to wear. At the same time, there are many types of such gears, and the specifications and sizes of each gear are not uniform.

[0003] The existing camshaft gear is fixedly connected to the camshaft. After the teeth of the camshaft gear are worn, it is not convenient to maintain or replace a new camshaft gear. The stability is low and the gear may fall off when the camshaft gear rotates. Therefore, those skilled in the art provide a camshaft gear that is easy to install and position to solve the problems raised in the above background technology. Utility Model Content
