NSK bearings to install and remove technique analysis

NSK bearing NSK bearings of NSK bearings installed installation: installation is correct, affect accuracy, life and performance. NSK bearings, therefore, the installation of the full research design and assembly department. Hope can be in accordance with the operation standard installation. Operation standard project usually is as follows: ( 1) Clean up the NSK bearings and related components; ( 2) Check the size of the relevant to the case and arrange components; ( 3) Installation; ( 4) NSK bearings after installation inspection; ( 5) Supply of lubricant. NSK bearings to install before, just opened the package. General grease lubrication, not clean, directly fill grease. Lubricating oil, is generally not clean, but using the instrument or with high speed bearing, rinse clean oil, removal of NSK bearings in corrosion inhibitor. NSK bearings, remove rust corrosion inhibitor, we can't put aside. In addition, has been sealed, vocational training bureau of oil bearing, don't wash directly. Installation method of the bearing NSK bearing structure, because conditions and, in general, the more the axis of rotation, so the inner ring interference meets the requirements. NSK bearings, cylindrical hole pressure pumped more, or the use of hot hot charging method. The installation of directly in the cone shaft or sleeve. Installed on the shell, there are usually more clearance, outer ring has a surplus quantity, usually by the press, or have installed the cooling of the shrink fit method. Dry ice as coolant, shrink fit installation, the moisture in the air condenses NSK bearing surface. Therefore, the proper anti-corrosion protection. Removal and installation of the NSK bearings NSK bearing removal techniques, should be careful. Be careful not to damage the NSK bearings and parts, especially NSK bearings and remove the interference, the operation is difficult. Before at the design stage, therefore, was given the disassembly convenient, disassembly tool, according to the need to design is also very important. Demolition and removal methods according to the drawing, in order to survey and bearing conditions for demolition and safe operation. 1, the outer ring of remove remove outer interference fit, the preset squeeze out a few screws, under the condition of outer periphery with a screwdriver, tighten the screws evenly, and demolition. These often include plug screw holes, NSK bearings taper roller bearings and other separation based, on the shell's shoulder several incisions station set up, using block, demolition and press delete or mining. 2, the removal of cylindrical hole demolition of the inner ring, pull with the latest simple mechanical stress. At this point, we should pay attention to the inner strength to withstand the pull. NSK bearing inner ring USES the method of hydraulic demolition. By setting up the oil on the shaft hole, so easy to pull. NSK bearing width is large and the hydraulic clamp, and in accordance with the law, and demolition. NU, NJ cylindrical roller bearing inner ring remove can make use of the advantages of induction heating. Local heating of in a very short time, so after the drawing method of internal expansion. 3, cone bearing NSK bearing set remove the removal of relatively small, circle, nut back several times to tighten the camshaft supports the use of a hammer remove pads,. NSK bearings, hydraulic remove more easy to use, in the hole pressure oil, internal expansion cone axis, demolition and bearing. NSK bearings in operation, the possibility of a sudden, it is best to use nuts and file blocks.
