1, reduce wear: when the transmission shaft rotates at high speed, the friction and wear will be great. Butter can play the role of lubrication, reduce wear and prolong the service life of the transmission shaft.
2. Anti-rust and anti-corrosion: the transmission shaft is often exposed, which is easily eroded by corrosive substances such as rain and sediment. Butter can play the role of rust prevention and corrosion protection, and protect the transmission shaft from corrosion.
3. Reduce noise: When the transmission shaft rotates at high speed, it will produce a lot of noise. Butter can reduce noise and make driving more comfortable.
4. Improve transmission efficiency: When the transmission shaft rotates at high speed, butter can play a role in lubrication, reduce friction, improve transmission efficiency, and make the vehicle more energy-saving. To sum up, lubricating the transmission shaft with butter can protect the transmission shaft, prolong its service life, improve transmission efficiency and reduce noise, which is a better method of adding grease. However, it should be noted that the types of butter and refueling methods used by different models and transmission shafts may be different, and the appropriate types of butter and refueling methods should be selected according to the suggestions of manufacturers.
