Over-adjustment Of The Brake Cable Will Damage The Countershaft Bearings And Needle Rollers

The brake cable material should ensure sufficient strength and wear resistance of the gear teeth, so the tooth surface of the sprocket is generally heat-treated to make it meet the specific hardness. Throughout the development of the sprocket industry, the market demand for standard sprocket will gradually decline, while the demand for non-standard sprocket products and the overall market share will gradually increase. In other words, non-standard sprocket has great market potential, and will gradually replace standard sprocket, becoming a development direction of the entire sprocket market, bringing a new development situation to the sprocket industry.

If the brake cable is adjusted too tightly, the countershaft bearings and needle rollers will be damaged, and the life of the rear wheel buffer body bearings will be greatly extended. The display of this situation is important because after the chain is tightened, a large compulsive holding moment will be formed between the countershaft and the rear wheel buffer body. Under the influence of this moment, the mission characteristics of the bearing will be destroyed. The surface is subject to greater force and is prone to heat and damage. In recent years, a lot of test work has been done on the fatigue performance of chain sprocket, which undoubtedly played an important role in guiding product design and manufacturing. Even if it is not damaged, the gap will increase in a relatively short time. After the bearing clearance increases, the straightness of the countershaft will be destroyed, and the needle roller bearing will be damaged soon. At this time, the hair problem will be transferred from the chain gear to the initiator. It can be seen that it is very important to adjust the tightness of the stainless steel chain of electric vehicles in a correct and timely manner.
