What are the functions of lubrication and sealing of rebar cutter?

A large part of the total scrap of rebar cutter is caused by poor lubrication and cooling. Therefore, the gears, bearings and sliders in the rebar cutting require good lubrication. Lubrication can reduce the friction loss and wear of the relative motion contact surface, and play a role in cooling and heat dissipation, rust prevention and removal of wear debris. The lubricating oil film between the contact surfaces can also alleviate the impact, reduce vibration and noise.



When the rolling bearings and sliding bearings in rebar cutter are poorly lubricated, it will cause the gluing of the bearing components, or the rolling elements will be tempered due to the high friction temperature, which will cause the bearing to fail. From the perspective of lubrication and heat dissipation, the rolling bearing in rebar cutter has a better lubrication effect.



The gears, rolling bearings and sliding bearings in rebar cutter are all lubricated with oil, so the type and viscosity of the lubricating oil are mainly determined according to the lubrication requirements of the gear transmission. In addition, the gears during cutting also have the function of slinging oil, so that the parts in rebar cutter are fully lubricated. However, it should be noted that when working under low temperature conditions, the lubricating oil should have sufficient fluidity so that the lubricating oil can flow into the bearing through the shaft hole and the oil groove to ensure the lubrication of the bearing.
