Description
technical field [0001] The invention belongs to the field of rotary valves, in particular to a rotary valve shaft and a processing method thereof. Background technique [0002] Because the rotary shaft valve has no reciprocating motion, less energy loss and simple structure, it has always been the direction of engine technology research and development. However, due to the contradiction between the shaft seal and heat dissipation performance of the rotary shaft valve, the problem of burning oil has not been well solved. Mass production is still not widespread. Contents of the invention [0003] The invention overcomes the deficiencies of the prior art, and provides a rotary valve shaft with simple structure, high efficiency and good elasticity, which can well solve the problems of thermal expansion of the existing valve shaft and lubricating oil scraping of the valve shaft and a processing method thereof. [0004] In order to solve the above-mentioned technical problems, ...
