Common electric tools include electric drills, impact drills, electric planers, electric hammers, electric grinders, electric wrenches and electric screwdrivers, etc. All electric tools contain high-speed motors, so electric tool bearings are an indispensable transmission component on electric tools. , The quality of the power tool bearing determines the quality of the power tool. Since power tool bearings are mainly used in motors in power tools, power tool bearings need to meet the following aspects.
1: High speed. The speed of the motor in the power tool is very high, so the electric bearing is required to have a high speed, 30,000 revolutions or even higher.
2: High temperature resistance. Long-term high-speed operation will generate high temperature, so the power tool bearings used are required to be able to withstand high temperatures.
3: High precision, the dimensional accuracy of the motor rotor in the power tool is relatively high, so the accuracy of the power tool bearing is also required to be relatively high, so that the power tool bearing and the rotor can be better matched, minimize resistance and friction, thus prolonging the power tool. lifespan. ,
4: High load, power tools need to carry a large load in actual use, so it is required that the power tool bearings can withstand high loads and are wear-resistant.
5: Dustproof and waterproof, the use environment of power tools is often exposed to dust and water, so dustproof and waterproof are very important for power tool bearings.
