Replace it every 3 to 6 months. Bearing repair Commonly used sliding bearing materials are bronze and babbitt alloy. The scraped tool traces should cross left and right until the contact spots within the contact angle range are uniformly dense, and the spindle level error is between 0. Detect the contact between the back of the jaw crusher and the bearing seat According to the requirements of 'JB\/T5000. Fine scraping and grinding of upper and lower tiles After the upper and lower tiles are coarsely and finely scraped and ground, the contact spots are still large, and further fine grinding is required. The oil storage point can be round or Wheel Bearings factory flat, the depth is generally 0. What causes the bearing to burn out at high temperature? How to avoid this 'stuffy car' phenomenon? If this situation occurs, how can we solve it? Faced with such problems, we will answer them one by one below. Jaw crusher bearings also use rolling bearings. Considering the changes caused by the temperature difference between the inner and outer rings and load factors, the best dimensional tolerance and radial clearance tolerance can be selected for the bearing. What should be done when removing the old tiles of the jaw crusher (1) Measure the thickness of the socket gasket on the joint surface of the old bearing bush.2mm\/m. The processing and matching dimensions of each component are closely related. After wear, the above repair methods are used to extend the service life of components, reduce production investment, and improve user economic benefits to a certain extent. Connection, the eccentric shaft and the frame are connected by two sets of bearings.05mm, and the general accuracy is ordinary. To The best way to solve the 'stuffy car' caused by bearing burnout is the best way to replace the bearing. Oil-sump lubricated or glycerin-lubricated bearings have more accidental wear and are usually repaired by manual scraping.2% of the shaft diameter, the side clearance should be 60% to 100% of the head clearance, and the axial clearance should be 1 to 3 mm. The inner hole of the steel sleeve and the journal should be an interference fit, and the outer diameter should be processed according to the original design size and tolerance.5mm, the area is 15\uff5e30mm2, and the total area should not exceed 1\/5 of the contact arc. The side gap of the bearing bush joint surface should be uniform and equal.
