NA crossed roller bearings specific installation steps

About INA crossed roller bearings imported detailed installation steps, we know that INA plain bearings are relatively common, proper installation method can make a better functioning of INA bearings, below said lower bearings INA bearings on the installation steps.
1, cleaning INA plain bearings and related parts
Already greased bearings INA bearings with seals or dust cover and bilateral, seals bearing joints before installation without washing.
2, check the relevant parts of the size and finishing conditions
3, the specific INA Bearing installation methods: INA bearings joint bearing joint bearing installation should be based on the structure, size and spherical plain bearings with the nature of the components, the pressure should be directly added to the tight fit was ferrule end face, not through the rolling transmit pressure, joint bearings installed generally use the following methods:
a, the installation of tapered bore bearings
Tapered bore bearings can be directly mounted on a tapered journal, or load the adapter sleeve and withdrawal sleeve cone, with the tightness of the availability of its joint bearing radial clearance reduction measure, therefore, before installation bearings should be measured radial clearance, the installation process should be measured regularly clearance in order to achieve the required clearance reduction until installation has generally adopted a locknut installation, heating installation methods may also be used.
b, thrust bearings installed
Comprehensive thrust bearing and shaft with generally transition fit, and joint bearing seat hole with clearance fit generally, so this joint bearing easier to install, two-way thrust bearings on the shaft central axis of spring should be fixed, to prevent rotation relative to the shaft. Joint bearing installation method, under normal circumstances is mostly the case of shaft rotation, so the inner ring and shaft with an exaggeration win cooperation, joint bearing joint bearing outer ring and the mating chamber for the clearance fit.
c, press-fit
Joint bearing inner ring and the shaft so that a tight fit, the outer ring and the bearing hole joints are more loose fit, use a joint press bearings will be pressed onto the shaft, and the shaft together with the joint bearing joint bearing hole mount , the press-fit bearing inner end surface of the joint, a soft metal material of pad assembly casing (copper or soft steel), the assembly of the casing diameter should be slightly larger than the journal diameter, outside diameter should be smaller than the diameter bearings slightly smaller than the inner wall, in order to avoid pressure on the retainer. Joint bearing joint bearing outer ring and housing bore a tight fit, the inner ring and the shaft for the more loose fit, can be pressed into the first joint bearing joint bearing hole, then the assembly should be slightly smaller than the outside diameter of the casing bore diameter. If the joint bearing ring and shaft and housing bore are a tight fit when installing the indoor ring and the outer ring to simultaneously pressed into the shaft and housing bore, the assembly casing shall be constructed simultaneously charge tight joints bearing inner and outer face .
d, heating with
By heating bearings INA Stainless steel slewing bearing or bearing joints, the use of thermal expansion will be a tight fit into a song with the installation. Is a common and effortless installation method. This method is suitable for a large amount of interference joints bearing installation, before the thermal loading or separable joint bearing joint bearing rings into the tank uniform heating 80-100 ℃, then remove from the oil as soon as possible onto the shaft on, after cooling to prevent the inner face and shaft shoulder fit is not tight, spherical plain bearings can be further cooled axial fastening. Joint bearing outer ring and light metal bearing joints tight fit, the use of a thermal heating joint bearing installation method, you can avoid with the surface by scratches. With tank heating rod end bearings, at a certain distance away from the bottom of the gate should network, or with a hook hanging bearings, spherical plain bearings can not be put on the bottom to prevent impurities sink into the joint bearing or uneven heating of the tank must have a thermometer, and strictly control the oil temperature does not exceed 100 ℃, in order to prevent tempering effect, reduce the hardness of the ferrule.
