Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to an anti-slip aluminum tube positioning sleeve for an engine camshaft. Background Art

[0002] The camshaft is a component in a piston engine. Its function is to control the opening and closing of the valves. Its material is generally high-quality alloy steel or alloy steel. Since the movement of the valves is related to the power and operating characteristics of an engine, the camshaft design occupies a very important position in the design process of the engine. Therefore, locating bushings are provided at both ends of the camshaft to achieve the purpose of sealing and wear protection of the camshaft. The locating bushing and camshaft have higher stability after docking.

[0003] The existing technology has the following problems:

[0004] In the prior art, the locating bushing is in constant contact and friction with the camshaft during use, which causes wear between the two. Lubricating oil is usually used to reduce the wear, but the current lubrication effect between the locating bushing and the camshaft is poor, which still causes these automotive parts to wear faster, thereby increasing the cost of using the vehicle.
