The invention belongs to the field of rotary air valves, and particularly relates to a reinforcing rotary air valve shaft and a processing method thereof. The reinforcing rotary air valve shaft and the processing method of the reinforcing rotary air valve shaft are characterized in that that the reinforcing rotary air valve shaft is simple in structure, high in efficiency and good in elasticity, and the problem that the conventional air valve shaft expands after being heated and scrapes lubricating oil can be well solved. The reinforcing rotary air valve shaft comprises an air valve shaft body, wherein the air valve shaft body is circular-tube-shaped; the axial connecting part of the air valve shaft body adopts a movable overlapping manner and the overlapped parts can expand and retract elastically; an air inlet and an air outlet are formed in the circular tube wall of the air valve shaft body; the air inlet and the air outlet are formed in the same circumference in the axial direction; a double-round-head rectangular partition plate is arranged in the air valve shaft body; the double-round-head rectangular partition plate separates the air inlet from the air outlet; arc-shaped elastic pieces are arranged between a middle rectangular plate and the circular tube wall of the air valve shaft body; a timing belt pulley is arranged on one side of the air inlet of the circular tube body of the air valve shaft body.
Description
technical field [0001] The invention belongs to the field of engine rotary valves, in particular to a reinforced 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 in the prior art and provides a reinforced 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 its processing method . [0004] In order to solve the above-mentio...
