The installation of TIMKEN bearings

For cone bearing inner ring installation always USES the interference fit. Unlike cylindrical hole bearing, cone bearing interference level is determined by the selected axis fit tolerance, but by the bearing in the cone shaft and shaft sleeve or withdrawal of the forward distance on the decision. Bearing the radial internal clearance as bearing on the cone shaft neck and narrow. By measuring the decrease value, the interference which can determine the degree of tightness and cooperate. Install the self-aligning ball bearing, CARB toroidal roller bearing, spherical roller bearing timken and with conical hole of high precision cylindrical roller bearing, to determine the radial internal clearance decreased value or cone base on axial forward distance, measure the amount of interference. Clearance decreased value and axial forward distance instruction, see related products. Small bearing small bearing can use nut, to advance to the cone base. In the case of the collar, then use the sleeve nut. Small sleeve nut available back into the bearing hole. Available to hook spanner or pneumatic wrench and tighten the screw as well. Before installation, should be on the surface of shaft and sleeve slightly a little oil. Large and medium-sized bearing large timken bearing the installation force increased significantly, and should use the hydraulic nut and/or filling method. The above two methods can significantly simplify the process of installation. Operating hydraulic nut and filling equipment for the oil injection method is used, there is supply. Detailed information about these products, see the line record the relevant part of the 'maintenance and lubrication products'. When using hydraulic nut bearing installation, it must be positioned in the thread section of the journal or the sleeve on the thread of the ring piston abuts on the shaft of bearing inner ring, nut or retaining ring on the shaft end. Through the pump oil into the hydraulic nut to safe and accurate force installation, move upward in axial piston. Using hydraulic nut, spherical roller bearings installed in the oil injection method, oil at high pressure injection timken bearing and shaft neck, forming a layer of oil film. This layer of oil film split mating surface, significantly reduce the friction between the mating surface. In the bearing directly installed to the cone axis neck, generally in this way, but also used in the designed for filling method set set and shirk set installed on the bearing. Oil pump or the necessary pressure lubricator, the groove on the shaft or sleeve and oil channel, the oil injection between mating surface. Bearing design layout, must consider necessary groove is arranged in the shaft and the channel. Spherical roller bearing installed on the grease groove of withdrawal, with the oil into the matching surface, and, in turn, tighten the screws, to press the withdrawal sleeve into the bearing hole. 【 The bearing network]
