5-153X GU1000 PRECISION 369 universal joint refers to the use of ball-shaped devices to achieve shaft power output in different directions, which is a very important part of the car. The combination of universal joint and drive shaft is called universal joint drive. In front-engine rear-wheel drive vehicles, the universal joint transmission is installed between the transmission output shaft and the transaxle final drive input shaft; the front-engine front-wheel drive vehicle omits the drive shaft, and the universal joint is installed on the axle And between the wheels, driving and steering.

In automobile drive trains and other systems, universal joints must be used in order to achieve power transmission between shafts that intersect or whose relative position changes frequently. The universal joint transmission is generally composed of a universal joint and a drive shaft, and sometimes there is an intermediate bracket, which is mainly used between the universal joint, the drive shaft, the front drive shaft, the intermediate support, the front and rear wheel drive cars of the engine and the transmission drive axle. The transmission device and so on.

When the distance between the transmission and the transaxle is very long, the drive shaft should be divided into two parts or even multiple parts, and an intermediate support should be added. A multi-axle drive car is located between the transfer case and the drive axle or between the drive shaft and the drive axle. Due to the deformation of the frame, a transmission member whose position changes between the two shafts is generated between the two transmission members. There is an independent suspension between the car and the differential. Steering between the axles and the differentials of the wheels. In the power output device and steering mechanism of automobiles.

There are several factors that affect the balance of uncorrected universal joints:

  1. Unbalance caused by manufacturing tolerances specified in the design specifications of universal joint parts.
  2. Unbalance caused by the eccentricity of the universal joint and the center of the shaft.
  3. Match the gap between the parts in the universal joint.
  4. Unbalance caused by the uneven distribution or asymmetry of the accessories in the universal joint.
  5. Unbalance caused by uneven material or uneven wear of universal joint parts.

Maintenance of universal joint cross shaft requires grinding gear oil. Since the lubricating oil nozzles of universal joint cross-shaft needle roller bearings are common lubricating grease fittings, they give people the illusion that they have been lubricated with grease for a long time. In fact, it is difficult to fill the butter bearing from the grease fitting to the needle bearing, and it is difficult to reach the end face of the horizontal shaft journal. Lubricating the universal joint manufacturer with butter can cause early damage to a large number of horizontal shaft needle roller bearings.
