PTO Drive Shaft Material and Types
The general parts of the cars,tractors,agri machinery transmission shaft are 45 steel, the external spline parts are 40Cr, the transmission shaft tube 440QZ, 480QZ shaft tube.
The transmission pto drive shaft is an important component of the transmission power in the vehicle drive train. Its function is to transmit the power of the engine to the wheels together with the gearbox and the drive axle, so that the vehicle generates driving force. The drive shaft is a shaft that transmits power in the drive shaft of the universal joint. It is a high-speed, low-supporting rotating body, so its dynamic balance is crucial. Generally, the drive shaft must be tested for dynamic balance before leaving the factory and adjusted on the balancer. For the front-engine rear-wheel drive car, the rotation of the transmission is transmitted to the main reducer shaft, which can be several sections, and the joints can be connected by a universal joint.
In order to ensure the normal operation of the drive shaft and extend its service life, it should be noted in use:
1, the car is strictly prohibited to start with high-speed files.
2. Do not lift the clutch pedal.
3. It is strictly forbidden to overload the car and speed.
4, should always check the working condition of the drive shaft.
5, should always check the fastening of the drive shaft hanger, whether the support rubber is damaged, whether the connection parts of the drive shaft are loose, and whether the drive shaft is deformed.
6, in order to ensure the dynamic balance of the drive shaft, should always pay attention to whether the balance soldering piece is off welding. The new drive shaft assembly is provided. When loading the new drive shaft, pay attention to the assembly mark of the telescopic sleeve, and ensure that the flange fork is in one plane. When repairing and disassembling the drive shaft, the assembly marks should be printed on the telescopic sleeve and the flange shaft in order to maintain the original assembly relationship during reassembly.
7, should always add grease to the universal joint cross bearing, in the summer should be injected with No. 3 lithium-based grease, in winter, No. 2 lithium-based grease.
