the disassembly, installation and operating environment of tapered needle bearing

Disassembly of the tapered needle bearing:

When the bearing is to be used continuously after it is removed, it should be properly disassembled. Disassemble the inner ferrule of the interference cooperation, and only add the pulling force to the ferrule. Never allow the detachment force to be transmitted through the tumbling body (outer ring), otherwise the tumbling body and the raceway will be crushed.

tapered needle bearing environment:

According to the application site, operating conditions and environmental conditions, the selection of specifications and accuracy, and the cooperation of suitable bearings is the condition to ensure the bearing life and reliability.
1. Application parts: Tapered roller bearings are suitable for receiving radial and axial combined loads mainly based on radial loads. They are usually used with two sets of bearings. They are mainly used for front and rear hubs, automatic bevel gears and differential speeds of passenger cars. Transmission parts such as reducer and reducer.

2, promise speed: in the correct, smooth and outstanding environment, the promise is 0.3-0.5 times the limit speed of the bearing. Under normal conditions, the limit speed of 0.2 times is optimal.
3, promised skew angle: tapered roller bearings generally do not allow the shaft to be skewed relative to the shell hole, if there is skew, does not exceed 2 degrees.
4, promise temperature: Under the normal load, and the smoothing agent has high temperature resistance, and the conditions are smooth and plentiful, the general bearing promises to work at an ambient temperature of -30 °C---150 °C.

tapered needle bearing device

1. Device method for thrust tapered roller bearing
Thrust cylindrical roller bearings and thrust needle roller bearings are suitable for low speed applications. Thrust tapered roller bearings Speed ​​flat thrust bearings are primarily used for axial loads in the body of the device and are widely used. Despite the operation of the thrust bearing device.

2. How is the gear and tapered roller bearing installed?
When designing the gear, there must be an axial positioning step, and the outer ring of the bearing should be dead. The outer ring of the inner ring is locked with a lock nut, and the pre-tightening force of the lock is set according to the use condition.

3. How to install and regulate the clearance of tapered roller bearings?
Generally, tapered roller bearings are used. Face-to-face and back-to-back can be used. The clearance size should be determined according to the size of the bearing you selected and the transmission accuracy required by the organization. As for the adjustment method, it can be done by pressing back.
