PTO
Shaft
PTO shaft, also called power take-off shaft, is a tool used to take power from a power source (such as a running engine) and transfer it to an application (such as an attached tool or a separate machine). PTO shaft is a rotating body with high speed and less support, so its dynamic balance is very important. Generally, the transmission shaft should be tested before leaving the factory and adjusted on the balancing machine. For the front engine rear wheel drive car, it is to transmit the rotation of the transmission to the shaft of the main reducer. It can be several joints, and the joints can be connected by universal joints.
PTO shaft
Effect
The PTO shaft is an important part in the transmission system of automobile. The function of PTO shaft is to transfer the power of the engine to the wheels together with the gearbox and drive axle, so that the automobile can produce driving force.
Purpose
The PTO shaft of special purpose vehicles is mainly used in oil tank trucks, oil tankers, sprinklers, sewage suction trucks, manure suction trucks, fire trucks, high-pressure cleaning trucks, road obstacle clearing trucks, aerial work trucks, garbage trucks and so on.

type-According to elasticity
PTO shaft can be classified according to its important part, universal joint. According to whether the universal joint has obvious elasticity in the direction of torsion, PTO shaft can be divided into rigid universal joint drive shaft and flexible universal joint drive shaft.
1. Rigid universal joint: PTO shaft transmits power by hinge connection of parts.
2. Flexible universal joint: PTO shaft transmits power by elastic parts and has the function of buffering and damping.
PTO shaft structure
The PTO shaft is composed of shaft tube, telescopic sleeve and universal joint. The telescopic sleeve of PTO shaft can automatically adjust the change of the distance between the transmission and the drive axle. Universal joint of PTO shaft is to ensure the change of the angle between the transmission output shaft and the drive axle input shaft, and realize the equal angular speed transmission of the two shafts.
a universal coupling
Universal joint is the key part of automobile PTO shaft.
PTO Shaft Use and maintenance
To extend PTO shaft service life, we should pay attention to:
1. It is forbidden to start the car at high speed.
2. It is forbidden to lift the clutch pedal abruptly.
3. Overloading and speeding are strictly prohibited.
4. Always check the working condition of the PTO shaft.
5. Always check the fastening of the transmission shaft hanger, whether the supporting rubber is damaged, whether the connection parts of the transmission shaft are loose, and whether the transmission shaft is deformed.
6. In order to ensure the dynamic balance of the transmission shaft, attention should be paid to whether the balance lug is desoldered. The new transmission shaft assembly is provided as a complete set. During the loading of the new transmission shaft, attention should be paid to the assembly mark of the telescopic sleeve to ensure that the flange fork is in a plane. When repairing and disassembling the transmission shaft, the assembly mark should be printed on the telescopic sleeve and flange shaft, so as to keep the original matching relationship unchanged when reassembling.
7. The universal joint cross bearing should be filled with grease frequently.
