Installation of bearing housing

Both the single motor bearing and the multi-bearing of the unit should be installed on the main longitudinal axis of the connected machine or the longitudinal axis of the unit. The bearing center is measured by hanging wire and wire hammer. (Clip a wooden strip in the bearing arc, and nail a thin iron strip in the center of the wooden strip to mark the center position).

To adjust the position of the shaft on the seat, start from the bearing seat on the farthest side, and use a spirit level on the bearing seat surface to check the levelness of these planes. Use a theodolite or a spirit level to check whether the planes of several axle seats are in the same horizontal plane, and use a wire hammer to find out whether the center of each bearing is on the same axis.

Adjust the bearing seat according to the above method. During the process of eliminating deviation, use a jack-type tool to move the bearing seat, and do not use the method of impact and hammering. The accuracy error of adjusting the bearing seat with this method is about 0.5~1.0 mm. It should be pointed out that the installation adjustment of the bearing seat is only a pre-adjustment, and it is also necessary to adjust the centering to meet the requirements of the consistent axis line. After the bearing seat is pre-adjusted, just tighten the screws evenly (tighten in a diagonal cycle), while the insulating sleeve and the stabilizer can be left temporarily until the centering work is finally completed or before the test run.
