buy Axle Shaft Motor shafts are generally made of high-quality carbon steel. Can choose 35#, 45#. Generally, 45# steel is used. These two materials belong to medium carbon steel, and their strength, rigidity and toughness can meet the working requirements of the motor shaft. The motor shaft has a high speed and low torque. It is made of 45# and does not require other heat treatment. The raw materials are in a normalized state, and the supply performance of the raw materials can meet the mechanical performance requirements of the motor shaft. The motor is represented by the letter M in the circuit (the old standard is D). Its main function is to generate driving torque. As the power source for electrical appliances or various machinery, the generator is represented by the letter G in the circuit. Its main function is The role is to convert mechanical energy into electrical energy. The motor should ensure that the motor is well lubricated during operation. The general motor runs for about 5000 hours, that is, the grease should be added or replaced. When the bearing is overheated or the lubrication is deteriorated during operation, the hydraulic pressure should be replaced in time. When replacing the grease, remove the old lubricating oil, and clean the oil grooves of the bearing and bearing cap with gasoline, and then fill 1/2 of the cavity between the inner and outer rings of the bearing with ZL-3 lithium-based grease (for 2 poles) And 2/3 (for 4, 6, and 8 poles).buy Axle Shaft website:http://www.sxforging.com/axle-shaft/
