YDDQ Bearing Manufacturing

The reducer is a power transmission mechanism that uses the speed converter of the gear to reduce the number of revolutions of the power source to the required number of revolutions, and obtains a large torque, in which the reducer bearing plays a gear shaft that supports the rotation or The role of the connecting rod is because the cylindrical roller bearing can obtain a continuous and stable supporting torque in an effective size range and has a certain amount of axial movement. Cylindrical roller bearings of the Nu NJ type are often mounted at the support positions at both ends of the shaft, and the double row eccentric bearing is used as a support position in the reduction gear, because it is not up and down, and a smaller mounting position can be obtained for deceleration.

Function editing
The role of the reducer bearing, there are many types of reducer bearings, commonly used rolling bearings and cylindrical roller bearings. There are many bearing series of reducer, such as SKF bearing, Fag bearing, NSK bearing, NTN bearing and TIMKEN bearing series.
The function of the reducer bearing is to keep the gear lubricating oil inside the bearing from escaping during use, to ensure that the bearing is in a lubricating state, and on the other hand to protect the dust or harmful gas from the bearing from entering the bearing cavity, in case The bearing caused damage. The bearing acts as a gear shaft or connecting rod that supports the rotation in the reducer.
In addition, the size of the reducer is different, and the bearing models are different. The reducer is a transmission mechanism that needs to transmit torque to the working machine through the shaft and the bearing. Therefore, the transmission efficiency and quality are directly related to the bearing. The sliding quality and life of the bearing will affect the overall quality and performance of the reducer.
 

Failure and solution editing
The reducer is one of the main equipments of the enterprise. Once the matching clearance occurs during the operation, it will cause serious damage to the drive shaft and the transmission gear, causing a major downtime and production accident, and the enterprise will suffer huge economic losses. Once the bearing chamber of the reducer wears out, the replacement cost of the parts is high, and the manufacturing cycle is long. The general repair method is disassembling the post-welding machining or reaming and inserting steel sleeves, which is time-consuming and laborious, and expensive. Western countries often use polymer composite materials to solve the wear problem of the bearing chamber of the reducer. 
This kind of problem is generally difficult to repair and repair by the repair welding method. The weldability of cast iron is not good and it is easy to cause more serious secondary damage to the parts during welding, and the replacement cost is high for a long time.
