Problems solved by technology

[0002] The camshaft is a commonly used component. The camshaft is generally composed of a cam formed on a shaft. The cam of the camshaft will bear a certain load force during use. After bearing the load force, the cam is often easy to produce wear or damage, but most of the existing camshafts are integrated with the cam and the support shaft. When the cam is worn or damaged, the entire camshaft needs to be replaced, which leads to an increase in cost and a low utilization rate of the camshaft. Low

Abstract

The invention discloses a cam shaft. The cam shaft comprises a supporting shaft and a cam sleeve, wherein the supporting shaft comprises a threaded section, a cam mounting section and an abutting section which are sequentially arranged; an abutting step is formed at the joint of the abutting section and the cam mounting section, the cam sleeve movably sleeves the cam mounting section, a fastening nut is screwed on the threaded section, one end of the cam sleeve abuts against the abutting step, and the other end of the cam sleeve abuts against the fastening nut to realize fixation of the cam sleeve on the supporting shaft. A detachable cam structure is adopted by the cam shaft, the cam is convenient to detach, the cam is stable in mounting, and it is guaranteed that the cam cannot fall off when the cam is operated.

Description

technical field [0001] The invention relates to a camshaft. Background technique [0002] The camshaft is a commonly used component. The camshaft is generally composed of a cam formed on a shaft. The cam of the camshaft will bear a certain load force during use. After bearing the load force, the cam is often easy to produce wear or damage, but most of the existing camshafts are integrated with the cam and the support shaft. When the cam is worn or damaged, the entire camshaft needs to be replaced, which leads to an increase in cost and a low utilization rate of the camshaft. Low. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a camshaft, which adopts a detachable cam structure, the cam is easy to disassemble, and the cam is installed stably, which ensures that the cam will not fall during operation. [0004] The present invention provides a camshaft, which includes a support shaft and a cam sleeve. The suppo...
