Subdivision bearing installed pay attention to the point

Subdivision bearing unit including cylindrical roller bearing, bearing, bracket and some connection parts. Bearing, bearing and stents were separated by the axis 180 °, easy to install and remove. Because of subdivision of bearing installation and disassembly, can effectively save the disassembly time, reduce production cost, improve production efficiency. But split bearings need to pay attention to some key points in the installation. Subdivision bearing point 1, and the installation of the bearing: install the split bearing, bearing and the bearing cover, the back of the bearing bushing hole should be closely contact with bearing housing. If it does not meet the requirements of platform bearing hole should be used as a benchmark. Should scrape the back of the bearing bushing and bearing split surface should be higher than the crack of the bearing surface of 0. 05 - 0. 1mm。 The point of contact between 2, bearing and bearing seat at the back of the area: not less than 40 on brick, brick under not less than 50, requires uniform contact area, no clearance between two blocks. Lower the bottom and sides of ceramic tile. Bearing liner under high pressure, can lead to rapid wear. The contacts between the bearing pad with bearing should be 1 to 2 points/cm2. Too little can lead to bearing pad aggravate wear, deformation and rupture. Point 3, the installation of the bearings and shaft neck: installing a bearing, must pay attention to the contact Angle between liner and shaft neck and the contact point. And the bearing contact surface between the pads and shaft neck should be relatively central Angle is called contact Angle. If the Angle is too big, will affect the formation of lubricating film, the lubrication effect, and make the bearing bushing wear quickly. Point 4, please pay attention to the adjustment of the bearing clearance when installation, usually should be controlled to the shaft diameter of 1/1000? 3/1000, can according to equipment load, speed and oil viscosity is optimized. Subdivision of the bearing structure is very special envoy, is widely used, the most important is easy to install, so can be used instead of the traditional bearing, is better than conventional bearing is easy to detect.
