Pre-loaded installation of KOYO angular contact ball bearing of important role

Bearing internal clearance before installation ( The original clearance) And after installation to angular contact ball bearing internal clearance when operating temperature ( According to work) Different, the former is big, with the applications of different, a lot of negative running clearance requirements, namely the applied load, the preload is to ensure that KOYO bearing under the condition of matching used in load to prevent damage due to skid. Main functions: to improve the bearing stiffness and reduce running noise, wear compensation in the operation of the enlarged gap and improve the guidance precision of the shaft, and extend the service life of bearing. Preloading is often the main indexes ( Dynamic load rating Cr) Best preloading load coefficient, still need to first calculate the preloading, confirmed by test constantly revised to determine the normal value, through the different adjustment methods to implement. In all KOYO bearing premature failure cases, about 25% are caused due to improper installation or use is not correct. A variety of applications may need to use heating, mechanical or hydraulic installation method to correctly and efficiently bearings. Choose to suit applications installation method will help extend bearing life, and to reduce premature failure due to angular contact ball bearing and for applications where the cost of potential damage. Oil bath heating bearings, KOYO bearings, this method may be pollution lead to premature failure of the bearing. Now induction heating is the most commonly used means of heating bearing, this is because its controlling, efficiency and safety are high. Some bearing manufacturer to determine the application of induction heater is used for bearing development standard. Bearing induction heater have many function, help to prevent damage to the bearings in the heating process. In general most small and medium-sized bearings mounted with cold. Traditionally, KOYO bearings is to use a hammer and a old pipe installation. This approach can lead to after rolling force components, and damage rolls. Angular contact ball bearing installation tools will be used outside force applied to press fit the bearing ring, helps to prevent damage of bearing. Bearing is installed in bearing used in the hydraulic technology pioneer, these techniques include filling method and displacement installation method. These methods can help simplify bearing configuration, conduce to the correct bearing and easy installation. Bearing the company also developed many installation tools and equipment used in bearing hydraulic technology, hydraulic technology to make these into practice. The shaft bearing before installation, must first remove the angular contact ball bearing a coat of fixed pin, at the same time the journal clean exterior burnish is smooth, and shaft neck with anti-rust and lubrication oil ( Allows for a slightly bearings on the shaft rotation) 。 Coating on surface of the bearing and the bearing lubricating oil, put the bearing into the bearing seat. Pushed to the required location for installation. Fixed bearing bolts do not tighten, let KOYO bearing coat rotation reaction in the bearing seat. Also installed on the same shaft, on the other side of the bearing and shaft turning laps, let angular contact ball bearing itself automatically find location. Then good bearing bolts.
