Oil inlet retractable universal connecting pipe of supercharger and method for manufacturing oil inlet retractable universal connecting pipe

Abstract

The invention provides an oil inlet retractable universal connecting pipe of a supercharger and a method for manufacturing the oil inlet retractable universal connecting pipe. The oil inlet retractable universal connecting pipe comprises a coupling and a pipe, and is characterized in that the coupling is movably connected with the pipe and can be expanded and contracted or can rotate relative to the pipe, grooves are arranged at joints of an inner cavity of the coupling and the pipe, and fluorine rubber sealing rings are arranged in the groove. The oil inlet retractable universal connecting pipe of the supercharger and the method have the advantages that the coupling of a pipe fitting is axially retractable after being modified, so that the problem that an existing pipe fitting cannot be assembled due to the fact that the existing pipe fitting is excessively long or excessively short is solved; the pipe fitting and the coupling are axially retractable and can axially freely rotate clockwise and anticlockwise, so that the problem that the head of the existing pipe fitting cannot be assembled due to angular deviation is solved; and the movable coupling and the head of the pipe fitting are molded by special technical processes, and the sealing rings made of fluorine rubber are additionally arranged between the movable coupling and the head of the pipe fitting, so that the mechanical vibration resistance of the pipe is improved, and the sealing performance and the durability of the pipe in a high-temperature oil environment are improved.

Description

technical field [0001] The invention belongs to the field of superchargers, in particular to a supercharger oil inlet telescopic universal connecting pipe and a manufacturing method thereof. Background technique [0002] At present, there is no uniform design specification for the auxiliary pipe joints of the superchargers produced by various manufacturers, and there are many differences in positioning, which causes inconvenience in the connection between the supercharger and the pipe fittings and the body. If there is a slight error, the pipe fittings will be too long or too short, and at the same time, oil leakage or assembly failure will occur due to the angle deviation when welding the head. Due to the vibration transmitted by the whole pipe fitting when the body is working, it will cause the pipe body to leak or break. [0003] Contents of the invention [0004] In order to solve the above technical problems, the present invention provides a supercharger oil inlet t...

AI Technical Summary

Problems solved by technology

[0002] At present, the superchargers produced by various manufacturers do not have a unified design specification for each subsidiary pipe interface, and there are many differences in positioning, resulting in inconvenience in the connection between the supercharger and the pipe fittings and the body.

If there is a slight error, the pipe fittings will be too long or too short, and at the same time, there will be oil leakage or failure to assemble due to the angle deviation of the welding head.

Due to the vibration transmitted by the whole pipe fitting when the body is working, it will cause the pipe body to leak or break.
