1. Heat resistance of the
gasket: At the end of the commutator, the
gasket and the oil ring are close to each other. Therefore, the material must be able to withstand the friction caused by the friction between the carbon and the commutator and the friction between the shaft and the cup. temperature.
2. Wear resistance of the
gasket: During the operation of the armature, the
gasket and the two cups of noodles fixed on the magnetic bottom rubber cover will constantly rub and wear. If the wear resistance of the material is not good, it will be easily damaged.
Gaskets reduce the life of the motor.
3. The moisture absorption rate of the
gasket is small: in a large environment, if the material has a high moisture absorption rate and linear expansion occurs, the armature may be stuck and the motor will be difficult to start.
4. Spring
gasket: good elasticity, fatigue strength, sufficient toughness, and sufficient wear resistance.
