Problems solved by technology

The starting shaft structure used in the current crankcase generally has oil leakage. The oil thrown out due to the rotation of the transmission component is very easy to leak outward along the shaft body of the starting shaft, resulting in insufficient oil in the crankcase and affecting the lubrication effect. At the same time, the leaked engine oil also pollutes the workplace

Abstract

The invention discloses a starting shaft oil leakage prevention structure of a single-cylinder diesel. The starting shaft oil leakage prevention structure comprises a crankshaft box, a gear chamber arranged in the crankshaft box, a starting shaft arranged in the gear chamber and a gear chamber cover arranged at one end of the crankshaft box. One end of the starting shaft extends out of the gear chamber cover to be connected with a fly wheel. An oval-ring-shaped sealing cavity is formed in the gear chamber cover. An oval-ring-shaped oil seal is arranged in the oval-ring-shaped sealing cavity. The oval-ring-shaped oil seal comprises a first oil blocking ring abutting against the inner side of the starting shaft and a second oil blocking ring abutting against the outer side of the starting shaft. A conical oil outlet hole is formed in the lower end of the part, between the first oil blocking ring and the second oil blocking ring, of the oval-ring-shaped oil seal, and an air inlet hole is formed in the upper end of the part, between the first oil blocking ring and the second oil blocking ring, of the oval-ring-shaped oil seal. An air inlet channel is formed in the crankshaft box.

Description

technical field [0001] The invention relates to a diesel engine accessory, in particular to an oil leakage prevention structure for a single-cylinder diesel engine starting shaft. Background technique [0002] The crankcase of a single-cylinder diesel engine is responsible for the transmission of engine power. The starting shaft structure used in the current crankcase generally has oil leakage. The oil thrown out due to the rotation of the transmission component is very easy to leak outward along the shaft body of the starting shaft, resulting in insufficient oil in the crankcase and affecting the lubrication effect. , At the same time, the leaked engine oil also pollutes the workplace. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an oil leakage prevention structure for the starting shaft of a single-cylinder diesel engine with good leakage prevention effect. [0004] In order to solve the above-mentioned te...
