What Are The Types Of Commonly Used Reducer Bearings?
Reducer bearings are special bearings used in various gear reducers. There are spherical roller bearings used in large gear reducers, such as 24044, 24048, etc., and cylindrical roller bearings are often used in small gear reducers.
The speed reducer is a kind of power transmission mechanism, which uses the speed converter of the gear to reduce the number of revolutions of the power source to the required number of revolutions and obtain a larger torque. The bearing of the gear speed reducer supports the gear shaft or the gear shaft between the rotations. The role of the connecting rod, because the cylindrical roller bearing can obtain a continuous and stable supporting moment within the effective size range, and has a certain amount of axial movement.
NU, NJ type cylindrical roller bearings are usually installed in the supporting positions at both ends of the shaft. And double-row eccentric bearings are used as the supporting position in the reduction gear, because they are not up and down out of concentricity, and a smaller installation position can be obtained. Reduce the size and weight of the speed reducer products.
In addition to cylindrical roller bearings, there are needle roller bearings, spiral roller bearings, tapered roller bearings, thrust ball bearings and other bearings used for speed reducers.
