Press-fitting roller device for cylindrical roller bearing and press-fitting method thereof

Abstract

The invention discloses a press-fitting roller device for a cylindrical roller bearing and a press-fitting method thereof, and relates to a press-fitting roller device. The press-fitting roller device comprises a workbench (6), a fixing device, a cylindrical roller bearing (1), holding frame window holes (3), a rod body (5) and a roller (4), wherein the fixing device is arranged on one side at the upper part of the workbench (6); the cylindrical roller bearing (1) is arranged on the other side at the upper part of the workbench (6); one end of the rod body (5) is moveably connected with the fixing device, and the other end of the rod body (5) penetrates through the inside of the cylindrical roller bearing; the middle of the rod body (5) corresponds to the holding frame window holes (3) formed in the inner wall of the cylindrical roller bearing (1); the roller is arranged in one of the holding frame window holes (3); the press-fitting roller device is simple in structure, and convenient to use, effectively improves the work efficiency, and does not damage the precision of the bearing during operation.

Description

technical field [0001] The invention relates to a press-fit roller device of a cylindrical roller bearing, in particular to a press-fit roller device and a press-fit method of a cylindrical roller bearing with an inner locking point cage. Background technique [0002] As is known, in the process of assembling rollers of cylindrical roller bearings with inner locking point cages, external forces are usually used to force elastic deformation of the inner diameter locking points of the cage, and after the rollers are pressed into the window holes of the cage, The deformation of the locking point is recovered, so as to lock the roller, so that the roller can rotate freely without falling from the window hole; at present, the process of pressing the roller is manually carried out, and the work efficiency is low. For larger size For bearings, it is necessary to have a large enough impact load to press the rollers into the window holes of the cage during press-fitting. Scratches o...

[0002] As is known, in the process of assembling rollers of cylindrical roller bearings with inner locking point cages, external forces are usually used to force elastic deformation of the inner diameter locking points of the cage, and after the rollers are pressed into the window holes of the cage, The deformation of the locking point is recovered, so as to lock the roller, so that the roller can rotate freely without falling from the window hole; at present, the process of pressing the roller is manually carried out, and the work efficiency is low. For larger size For bearings, it is necessary to have a large enough impact load to press the rollers into the window holes of the cage during press-fitting, which is difficult to operate. When using manual press-fitting, the rollers will be unevenly stressed, which can easily cause Scratches on the rolling surface and deformation of the cage, thereby affecting bearing accuracy
