The lubricating film of the T series rubber timing belt is mainly formed through the self-lubricating mechanism generated by friction and heat. It can reduce friction and wear during movement, improve transmission efficiency and extend service life. The specific formation process of lubricating film includes the following steps:
1. Contact friction: When the T series rubber timing belt engages with the gear, a certain amount of friction will be generated due to the tooth-shaped engagement transmission. This friction forces the surface of the rubber material into close contact with the surface of the gear.
2. Friction heat generation: During the process of contact friction, a certain amount of heat will be generated due to the conversion of friction energy into thermal energy. This heat can increase the surface temperature of the rubber material and promote the formation of a lubricating film.
3. Activation of rubber surface molecules: As the surface temperature of the rubber material increases, the rubber molecules will become more active. These active rubber molecules interact with surrounding air or lubricant molecules to form a lubricating film.
4. Formation of lubricating film: As the surface temperature of the rubber material increases, active rubber molecules will gradually diffuse to the surface and combine with surrounding oxygen or lubricant molecules to form a thin lubricating film.
