Deep Groove Ball Bearings The main components
Deep groove ball bearings are the main parts of the machine, the machine is flexible operation, mainly depends on the quality of stainless steel deep groove ball bearings to ensure the quality of assembly should grasp the disassembly method.
First, the deep groove ball bearing disassembly
1. Sliding deep groove ball bearings and bearing the demolition
Sliding deep groove ball bearings are generally thinner, easy to damage and strain. When removing, first remove the fixing screws and pins around the deep groove ball bearings. Positioning flange of the deep groove ball bearings, stainless steel deep groove ball bearing cover and deep groove ball bearing seat should be separated from the direction of attention. When removing the tiles, apply copper rods or sticks to withstand the steel back of the end of the bearing, and pay attention to the protection of the alloy layer. Sleeve bushings should be removed or extruded using a disassembly tool, which can not be knocked to avoid deformation and damage to the bearing.
2. Rolling deep groove ball bearing disassembly
Before removing the deep groove ball bearings, please check to determine the direction of removal, pay attention to whether the axial positioning device. When removing deep groove ball bearings from the shaft, the force points should be selected on the inner ring of the deep groove ball bearings;
, The force should be selected in the deep groove ball bearing outer ring, the demolition force to be uniform, to prevent deep groove ball bearings skew.
Second, the installation of deep groove ball bearings
1. Sleeve Sliding Deep Groove Ball Bearings Installation
Installation to ensure that the shaft and deep groove ball bearings between the appropriate gap in order to lubricate the formation of oil film. Deep groove ball bearings and seat holes should be widely equipped with appropriate tightness to prevent the operation of deep groove ball bearings with the shaft rotation. Specific requirements are as follows:
① before the pressure should be checked before the thickness of the deep groove ball bearing parts meet the requirements, with or without defects, and wipe the surface of the dirt, smear lubricants, oil clean up and alignment on the body of the oil hole.
② According to the stainless steel deep groove ball bearings on the body position and deep groove ball bearing size, in the installation of the appropriate tools.
③ deep groove ball bearings press fit, the non-interference fit should be added with screws or pins, and to check the diameter is in line with the requirements, such as deformation, it must be trimmed, the general use of boring, reaming and scraping method The
2. Installation of Sliding Deep Groove Ball Bearings
① open sliding deep groove ball bearings are usually said bearing, in the installation should be cleaned before the oil, oil tank, the mating surface, check the deep groove ball bearing and pad on the oil hole is relative. Pay attention to remove the rust-proof wax on the axle pieces, shall not use the fire, so as not to overheat the molten metal, should be placed in hot water or hot oil after melting clean.
