Bearing applications in Gantry Crane

    Bridge, gantry crane and trolley carts wheels were powered by a 90 ° angle of the bearing housing assembly together into the wheel group, the overall adjustment tack welding station in the traveling frame, such a structure in the country has become a series of products, and widely used. It is characterized by the frame does not need to go on-line station processing, assembly more convenient. According to the case currently in use, taking into account the load-bearing parts crane wheels are in operation will be affected by the quality of rail and wheel installation itself manufacture and assembly deviation factor deviation, resulting deflect wheel slip, skew and other phenomena while the skew is important to be the one of the factors considered in the design. The main factor in the quality and the wheel itself to manufacturing variations, the deviation of the wheel assembly became gnawing rail mounted on the removal of track. So I plant using a 45 ° angle to assemble the wheel set ship loader bearing, mounted on a 35t and 10t container gantry crane gantry cranes General, and achieved good results.
  (1) The main features ① As the bearing welded to the station frame, supporting hole machining the bearing bore and the overall balance beam with a shape, by working to ensure the accuracy of assembly requirements, thereby greatly reducing the deviation of the wheel assembly group. ② repair, replacement parts wheel set is more convenient. (2) a few questions in the actual design and applications should be noted ① and balance beam supporting the mobile crane bearing

 bore hole while the design on the table frame, the processing, the installation process should be completed in time to ensure that its hole center line parallel, but also to ensure the balance of the wheel center plane of the support points.
