Bearing insulation structure

An insulating pad or metal gasket must be placed between the bearing and the base plate, which is used to adjust the horizontal position of the seat. To adjust the relative position of the motor and another motor or machine connected thereto. The metal gasket is made of 0.08-3mm metal sheet. The insulating backing plate is made of a cloth laminate or glass fiber laminate. The main purpose of placing insulating pads is to prevent the harm of shaft currents. The insulating backing plate should be 5-10 mm wider than each side of the bearing seat and have a thickness of 3-10 mm. In addition to placing insulating pads between the bearings and the base plate, the screws and stabilizing nails should also be insulated. The insulating gasket is made of glass fiber cloth plate with a thickness of 2-5 mm, and its outer diameter is 4-5 mm larger than the outer diameter of the iron gasket. The insulating pad of the oil pipe connecting plate connected to the bearing seat can be made of a rubber plate with a thickness of 1-2 mm. After the installation of insulated bearing blocks, the insulation resistance to ground should be checked and measured with a 500 volt megohmmeter. The resistance value should not be less than 1 megohm.
