Decomposition Method of Full Complement Cylindrical Roller Bearing Based on Spiral Test Rack

Abstract

The invention relates to a spiral testing rack based disassembling method of a full complement cylindrical roller bearing. The method comprises the steps that the full complement cylindrical roller bearing is arranged on a spiral testing rack clamp; the clamp can axially clamp and fix a cylindrical roller of the full complement cylindrical roller bearing, and an outer ring of the full complement cylindrical roller bearing is suspended; then the outer ring of the bearing is propped through a propping roller of the spiral testing rack, thus the cylindrical roller can be separated from a roller path in the outer ring of the bearing, and the press-out force of the roller can be measured at the same time; the direction of the propping force of the propping rod is in the same straight line as the direction that the cylindrical roller is separated from the roller path in the outer ring of the bearing; the aforementioned steps are executed again to achieve the disassembling of the roller and the outer ring of the full complement cylindrical roller bearing. The method can fill a void of an existing dismounting and disassembling method of the full complement cylindrical roller bearing; the operation method is simple and cannot lead to damage to the bearing; meanwhile, the full complement cylindrical roller bearing can be conveniently detected, and the bearing can be conveniently optimized and improved.

Description

technical field [0001] The invention relates to a method for disassembling and disassembling a bearing, in particular to a method for disassembling a full complement cylindrical roller bearing. Background technique [0002] Full complement cylindrical roller bearings are designed to accommodate heavy loads. Under the same width, compared with traditional cage bearings, this kind of bearing has extremely high load capacity, and the radial section is small, which can save space, but the speed is relatively low. [0003] At present, there is no effective disassembly technology for full complement cylindrical roller bearings, and other factors such as scratches on the roller surface and raceway surface are likely to be caused during disassembly. The spiral test rack is a small test machine equipped with a push-pull force gauge and various fixtures, but there is no relevant information on its use in bearing disassembly.
