Description

Technical Field

[0001] The utility model relates to the technical field of coating protection, in particular to a coating protection device for a buffer disc of an intermediate transmission shaft. Background Art

[0002] The transmission shaft is a high-speed, less-supported rotating body, so its dynamic balance is crucial. Generally, the transmission shaft must undergo a dynamic balance test before leaving the factory and be adjusted on a balancing machine. For front-engine, rear-wheel-drive vehicles, it is the shaft that transmits the rotation of the transmission to the main reducer. It can have several sections, and the sections can be connected by universal joints.

[0003] For the intermediate transmission shaft in the transmission shaft, the intermediate support buffer plate (such as Figure 5 The intermediate transmission shaft (as shown) is a key part of the intermediate transmission shaft. Before the intermediate transmission shaft is sprayed, it is necessary to clean the intermediate transmission shaft with a high-pressure water gun to remove impurities on the intermediate transmission shaft, thereby ensuring the quality of the subsequent spraying process. At this time, since the intermediate support buffer disk on the intermediate transmission shaft does not need to be sprayed, the support buffer disk is usually sprayed together or the support buffer disk is briefly wrapped with tape before cleaning the intermediate transmission shaft.

[0004] However, there are still some problems with the above-mentioned treatment of the support buffer disk. If the buffer disk is sprayed together with the intermediate transmission shaft, the rubber surface of the buffer disk will also be painted. Due to the surface oil and other additives in the rubber material during the molding process of the rubber material product, it is difficult for the surface paint film to be firmly bonded with the substrate, and the paint surface will peel off after a period of time. If the support buffer disk is temporarily wrapped with tape before cleaning the intermediate transmission shaft, the tape wrapped around the buffer disk will be easily washed away when the intermediate transmission shaft is flushed with a high-pressure water gun, resulting in the phenomenon of spraying paint on the buffer disk. Utility Model Content

[0005] The utility model aims at the problems in the prior art and provides a coating protection device which can stably protect the buffer disc during the cleaning and spraying process in the transmission. The utility model solves the problem that the buffer disc is sprayed together with the intermediate transmission shaft in the prior art, resulting in the rubber surface of the buffer disc also being coated with paint. Due to the surface oil stains on the rubber material products during the molding and production process and other added components in the rubber material, it is difficult for the surface paint film to be firmly combined with the substrate, resulting in the problem of paint peeling after a period of time. At the same time, it also avoids the problem that the buffer disc is temporarily wrapped with tape, so that when the intermediate transmission shaft is subsequently flushed with a high-pressure water gun, the tape wrapped around the buffer disc is easily washed away, resulting in the problem of spraying paint on the buffer disc.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A paint protection device for an intermediate transmission shaft buffer disk includes a first sleeve and a second sleeve, wherein the first sleeve is used to be sleeved on a part of the buffer disk, and the second sleeve is used to be sleeved on another part of the buffer disk.
