Subdivision bearing installation note four items

Subdivision bearing unit including cylindrical roller bearing, housings, bracket and some attachment, bearings, bearing, stents are along the axial 180 ° cutting apart, easy to install and remove. Because of subdivision bearing installation disassembly, can effectively save dismantling time, reduce production cost, improve production efficiency. But also need to install it with some matters, whether it is easy to cause split bearing damage, the bearing network according to understand, to share split bearing installation notices of the big four. 1, the bearing seat installation: split bearing, bearing, bearing cover when installation should make good bearing bush back in contact with the bearing hole, such as does not conform to requirements should be based on the bearing hole, blow grind bearing bush back, bearing subdivision surface should be higher than the subdivision surface bearing 0. 05 ~ 0. 1mm。 2, the contact area between the bearing and the bearing seat on the back: on tile shall not be less than 40%, shall not be less than 50%, under uniform and contact area, don't allow the tile bottom with a gap on both sides, once the tile has a gap on both sides, load bearing to increase the pressure, leads to wear soon. Between the bearing and the bearing seat contact spots should be 1 ~ 2 PM/cm2, too little will cause bearing wear deformation. Installed 3, bearing and shaft neck: bearing, must pay attention to the bearing and the shaft collar contact Angle and the contact point. Bearing and shaft neck corresponding to the contact area between the central Angle is called contact Angle, the Angle is too large influence the formation of lubricating film, the lubrication effect, make the bearing wear soon; Starts to increase the bearing pressure, also can make bearing wear. General contact Angle in the 60 ~ 90 degrees. Contact point between bearing and journal about equipment load, medium load and continuous operation of 2 ~ 3 PM/cm2, heavy load and high speed running equipment 3 ~ 4 PM/cm2, accords with a requirement to make the contact Angle and the contact spot, will adjust their research. On tile after blow grind lower, first, on the shaft neck apply a thin layer of red paint, put the shaft on the bearing, the positive and negative direction of the rotating once removed, such as uneven found mark should be developed, have imprinted on the bearing shell is uneven, should be scraping, repeatedly, until the mark on the bearing shell uniform distribution, meets the requirements. 4, when installation, pay attention to the adjustment of the bearing clearance, general is to control in the shaft diameter of 1/1000 ~ 3/1000, according to the specific equipment load, speed, oil viscosity to grope for optimization. Because of the special tectonic subdivision bearing, application is very extensive, the most important reason is to replace conventional bearing of convenient installation, is very simple and highly effective. Compared with the conventional bearing, subdivision easier to detect bearing accessories. Quickly remove the lid of bearing and the bearing box, all bearing accessories can be convenient and visual, easy to participate in the maintenance phase plan work. Visible, compared to conventional bearing, split bearings can save a lot of testing process. 【 Warm prompt. 【 The bearing network] Some information from the Internet, and strive to secure timely, accurate, aims to deliver more information, does not represent our views to its approval or responsibility for their authenticity.
