About the bearing installation, the following points: you know what?

Motor bearing damage used to say, but do you know, 80% of the bearing is invalid because there is no installation properly in advance. Bearing the proper installation, not only can improve the motor bearings, could the control cost, also can further improve the economic benefit. Bearing installation and basic component has very big difference, in order to complete the 'closed' must grasp the special way and the method. Before installation, must be sure that motor bearing is stored intact, it is to ensure that the key prerequisite for bearing installation. Bearing the storage of bearing the storage on the natural environment have relativity stringent regulations, storage of the natural environment such as warehouse, temperature should be kept in 0 ~ 40 degrees, environment humidity remain below 60%, without a lot of smoke and dust, corrosion gas bearing factory is a new packing is in good condition and is equipped with rust preventive maintenance, as far as possible keep the original packaging before applications are prepared ahead of time, did not do well protection measures to prevent or reduce and cause bearing corrosion. Motor bearing installation to ensure that are properly stored bearing intact, can be installed. The first step in the abundance of the necessity of the preparation, store under normal circumstances, all bearing before installation should be stored in their original packaging. They must leave to clean up, no moisture and relativity in the temperature control of the natural environment. Rolling bearing should put an end to the dust, water and corrosion of compound. In advance (coated with grease Or seal) Bearings must be very careful, because the grease will change after long-term storage of relative density. So when bearing application for the first time, there will be a certain level of rotation noise. Therefore, this type of bearing idle time should be a standard to manipulate the first-in, first-out method. , ready to install all the necessary special tools fully ready installation necessary spare parts and special tools during the whole process, include the screw nut, screw glue, seal, electric heater, Or a cooler) , lifting tools, torque wrench, inside diameter micrometer, magnetic holder, inner dial indicator ( Or dial gauge) , and other auxiliary equipment. , early for the precise measurement of the important parts specifications and records on the basis of the general design of bearing, there is a transition fit by the rotating components are, stationary components can use transition fit. Before installation, to the important parts of the specifications of the early carry out accurate measurement and record is the necessary stage, prevent don't pass the damage parts installed on the bearing. Step 2 choose suitable installation for a bearing with transition fit generally rely on heating to make the inner ring aspect up into (or press immediately Applicable specifications are not only large bearing) Methods such as the installation. , inner ring heating peng up bearing inner ring heating mode: common magnetic bearing inner ring, heat treatment furnace heating and oil bath. Common heating mode is:, according to press into this kind of way is only small size bearings. First, work pressure must be matching in time. According to the formula to calculate the police need to press tonnage. Second, choose suitable work clothes to match press tension and pressure of the bearing components, is generally socket specification class parts and bearing parts touching the whole week. In the end, it is also one of particularly important processes, working pressure to immediately release on the must get rid of the interference force components. If the inner ring with experience surplus situation, for example, not according to the lateral pressure, using dovetail guideway and roller bearing the force transmitted to the inner ring to finish riveting, that leads to the damage of bearing raceway. After the third step loading test, double insurance no matter choose which kind of installation method, after the installation of detection can prevent due to some process careless bearing riveting is not in a timely manner. In view of the motor bearing press press into the installation, if the circular arc and a half after a big shoulder position, even more than the circular arc of the bearing, then after loading inspection becomes find corrected for example pumped, deviation of production and processing, and not in time sequence leak check necessary process such as problem before. The above is the content, the author has given you today to learn more about bearing small knowledge, pay attention to the bearing's official website, share to you is not the same as bearing small knowledge every day.
