The bearing runs inside and outside, that is, the bearing runs inside and outside the ring. Pitting process The pitting repair process is an emergency measure. The bearing room is pitted or knurled. The bearing and the shaft (hole) fit very tightly, generally an interference fit, and in a few cases a transition fit. 1.5-2mm, curing at room temperature for more than 24h, processing on the lathe, the tolerance is controlled within In the H6 range, the roughness is 1.

 

This measure has a wide range of applications and can be used in large and small bearing chambers.1.) to heat powdered or filamentous metal or non-metallic materials to a molten or semi-molten state, and then spray it at a certain speed with the help of flame itself or compressed air A technology in which the surface of the pretreated substrate is deposited to form a surface coating with various functions. If you can’t buy the end cap of the original machine for various reasons, you can use the original end cap as a model,tensioner bearing kit manufacturers sand casting or steel plate welding blank, pay attention to repairing the sand mold to leave the machining allowance of the metal processing part and the shrinkage of the casting cooling. Solei carbon nano polymer repair technology Soleil carbon nano polymer material repair technology is a kind of 'cold repair' technology, which can implement offline machining repair, or implement on-site online repair, which is more flexible in application.

 

Fitting tolerance: There are strict standards for the fitting tolerances of bearings and shafts (holes). This measure is one of the most ideal repair programs. After cleaning the dust and other debris, you can reinstall it. The inner diameter and length of the steel sleeve are reserved for the machining allowance after nesting. As long as the basic mechanical strength of the shaft head meets the use, it can be repaired by this technology. Pay attention to ensure that the arc surface of the rubber strip is slightly higher than the cylindrical surface in the bearing chamber. 2. Machining accuracy and installation accuracy: refers to the technical parameters of shaft, bearing, bearing seat hole processing tolerance, surface roughness, installation and assembly accuracy.

 

Under the torsion force, the shaft (bearing) will break the static between each other and cause sliding. If either aspect is not good, the bearing may run into circles. The interference between the bearing and the shaft is insufficient, resulting in insufficient friction between the bearing and the journal and running the inner ring. The inner diameter tolerance is controlled at H6, and the roughness is 1.
