Inner ring single side cylindrical roller bearing installation
The inner wall of single cylindrical roller bearing installation 1, cleaning cylindrical roller bearings and related parts of grease lubricated cylindrical roller bearing and oil seal with bilateral or dust cover, sealing ring of cylindrical roller bearing before installation without cleaning. 2, the installation method of cylindrical roller bearings should be installed according to the cylindrical roller bearing with the structure, size and properties of cylindrical roller bearing components. The pressure should be added directly in a tight fit to ring face, shall not transfer the pressure through the rolling body, cylindrical roller bearing installation generally adopts the following methods: A. press fit cylindrical roller bearing the inner ring and the outer ring and the shaft is tightly matched with the cylindrical roller bearing hole is a loose fit, available press roller bearing pressure mounted on the shaft, and the shaft together with the cylindrical roller bearing into a cylindrical roller bearing seat hole, pressing in cylindrical roller bearing inner ring end face assembly sleeve pad a soft metal material (copper or steel), the assembly sleeve diameter should be slightly larger than the shaft diameter, the diameter ratio of cylindrical roller bearing inner diameter should be blocked While slightly smaller, to avoid pressure on the holder. Cylindrical roller bearings with cylindrical roller bearing hole is tightly matched with the inner ring and shaft is a loose fit, can be pressed into the first cylindrical roller bearing cylindrical roller bearing seat hole, when the assembly sleeve diameter should be slightly smaller than the diameter of the hole seat. If the cylindrical roller bearing ring with the shaft and hole are tight fit, installation of interior ring and the outer ring and pressed into the shaft and hole structure, the assembly sleeve should be able to face and the inner and outer tight cylindrical roller bearing.
When installing cylindrical roller bearings, the verticality of the shaft ring and the center line of the shaft shall be checked. The method is to dial fixed on the box shell face, touch the top of the table in the cylindrical roller bearing ring raceway on rotating cylindrical roller bearings, while observing the dial pointer, pointer to swing, the shaft and shaft centerline vertical. When the case is deep enough, it can also be tested with an extended thousand head meter.
