Problems solved by technology

[0002] The spherical roller bearing itself cannot carry large axial loads. When the working conditions are bad or the working time is long, the shaft and the bearing will move axially at the matching position, resulting in wear of the shaft and the bearing, affecting the stability of the equipment, and seriously It will cause damage to the equipment, so it is necessary to have a special device to prevent the axial movement of the drive shaft to ensure the stability of the equipment and the safety of the equipment.

Abstract

The invention discloses a device for preventing axial drifting. The device comprises a locking sleeve with a through hole in the middle and a cylindrical boss on the outside. The locking sleeve is arranged on a transmission shaft in a sleeving mode through the middle through hole and fixedly connected with the transmission shaft. An inner ring of a thrust self-aligning roller bearing used for transmitting radial rotation is fixed to the cylindrical boss of the locking sleeve in a sleeving mode. An outer ring of the thrust self-aligning roller bearing is fixed to the inside of a groove of a bearing support in an embedded mode. The bearing support is fixed to a bearing seat. The device is safe, reliable and durable.

Description

technical field [0001] The invention relates to a device for preventing axial jolting of a drive shaft, in particular to a device for axial jolting of a drive shaft for assembling self-aligning roller bearings. Background technique [0002] The spherical roller bearing itself cannot carry large axial loads. When the working conditions are bad or the working time is long, the shaft and the bearing will move axially at the matching position, resulting in wear of the shaft and the bearing, affecting the stability of the equipment, and seriously It will cause damage to the equipment, so it is necessary to have a special device to prevent the axial movement of the drive shaft to ensure the stable operation and safety of the equipment. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a device for preventing axial movement that can avoid axial movement at the matching position of the shaft and th...
