The invention belongs to the field of rotary valves, and in particular relates to a reinforced rotary valve shaft and a processing method thereof; it provides a valve shaft with simple structure, high efficiency, good elasticity, and can well solve the problem of thermal expansion of the existing valve shaft and the scraping and lubrication of the valve shaft. Reinforced rotary valve shaft for oil problems and its processing method; including the valve shaft body, the valve shaft body is in the shape of a round tube as a whole, the axial connection of the valve shaft body adopts movable lap joints and the overlapping parts can be elastically stretched, the round tube wall of the valve shaft body The air inlet and the exhaust port are arranged on the top, and the air inlet and the exhaust port are arranged on the same circumference in the axial direction. There is a double-round rectangular partition inside the valve shaft body, and the double-round rectangular partition connects the air inlet and the exhaust. The air ports are separated, an arc-shaped shrapnel is arranged between the rectangular plate in the middle and the inner wall of the circular pipe, and a timing pulley is arranged on the side of the air inlet of the circular pipe of the 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...
