Sealing sleeve structure transmission shaft

Abstract

The invention discloses a sealing sleeve structure transmission shaft which comprises a universal joint fork, a movable sleeve, a spline groove, a tension band, a buckle, a gasket, a gasket cover, a groove, a shaft pipe and a sleeve, wherein the movable sleeve is fixedly installed on the back side of the universal joint fork by a bolt, and the gasket is rotatably connected to the interior of the movable sleeve through the spline groove; and the groove is integrally formed in the surface of the gasket cover, and the tail end of the sleeve is integrally connected with the tension band. According to the sealing sleeve structure transmission shaft, the sleeve with one end welded on the movable sleeve is arranged at the exterior of the movable sleeve and the spline groove of a conventional transmission shaft; the other end of the sleeve is riveted with the groove with the gasket cover through the tension band with the buckle, and therefore the sealing treatment can be carried out while the effective disassembly is guaranteed; external pollution is avoided, and an inner pad is arranged between the sleeve and an inner pipe; the inner pad is composed of oil absorption cotton, a bamboo charcoal plate and a lime plate, and it is guaranteed that the interior is dry and clean; and the structure is simple, and the transmission shaft is easy to achieve.

Description

technical field [0001] The invention relates to the technical field of transmission shafts, in particular to a transmission shaft with a sealing sleeve structure. Background technique [0002] The transmission shaft is a rotating body with high speed and few bearings, so its dynamic balance is very important. Generally, the transmission shaft must undergo a dynamic balance test before leaving the factory and be adjusted on a balancing machine. For front-engine and rear-wheel drive vehicles, it is the shaft that transmits the rotation of the transmission to the final drive. It can be several sections, and the sections can be connected by universal joints, and the sealing sleeve is used to cooperate with the transmission. A device used for shaft sealing. [0003] The existing transmission shaft can be used with machinery, but in actual use, the movable sleeve and spline groove of the transmission shaft are exposed to the outside for a long time during contact with the air. ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a transmission shaft with a sealing sleeve structure to solve the problem that the movable sleeve and the spline groove of the transmission shaft proposed in the background technology are exposed to the outside for a long time during contact and use, and the surface of the spline groove will be damaged when in contact with air. The contact between the lubricating matter and dust will cause agglomeration and oxidative drying of the lubricating matter, which will affect the smoothness of rotation and require frequent cleaning, which will affect the precision of the transmission shaft in the long run
