Spindle bearing installation method of the main shaft bearing installation considerations

Spindle bearings are precision machine tool spindle bearings, and similar devices to guarantee the working accuracy of precision machine tools and the use of performance, bearing in the installation of improper operation often result in bearing damage in advance or early use of loss. Greatly improve the bearing cost; So, main shaft bearing matters needing attention are: 1, the cleaning and inspection of large bearing motor bearing is separate packing and shipping. After open the box, take off, the ceramic tile, with ring screw tag, clean with kerosene. Dry cloth is used to dry and check whether all groove is clean, if there are any residual sand casting. Tungsten gold layer combined with ceramic tile is not good, such as channel, crack mixing. If you can't repair, should be suspended tungsten and gold again. 2, the cleaning and inspection before installation of the bearing should also be thoroughly clean and check the bearing seat. And the inner cavity of the bearing with scraper scrape, with dip in solvent gasoline or cloth to wipe away dirt, look for cracks and bunkers, to prevent oil leakage in the process of operation. Bearing cover and bearing seat, bearing and the bearing block of oil ring joint surface should cooperate, leveling and feeler check. Clearance should not be greater than zero. 03mm。 Shell bottom surface should be clean and shall not contact, rust and burr. Should carefully check and test the tighten screw and plate threaded casing, to determine whether the screw is too tight or too bald. 3, margin structure between the bearing and the bottom bearing must be side of mat mat or metal gasket. Metal gasket is used to adjust the horizontal position of the seat. Adjust motor connected to the motor or the relative position of the machine. Metal gasket by 0. 8 mm pieces of metal. Edge cushion made out of cloth laminate or glass fiber laminate. Placing flange pad purpose is to prevent the harm of axial flow. Than shell flange pad should be on both sides of 5 to 10 mm wide, 3 to 10 mm thick. In addition to bearing and bottom edge between pads, screws and stabilizer should be edge. Flange gaskets by thickness of 2 mm, 5 mm of glass cloth, its outer diameter bigger than the outer diameter of iron washer 4 mm, 5 mm. Connected to the oil pipe flange on the bearing seat cushion can be made from 1 mm thick rubber sheet. Flange bearing seat after installation should check to answer the geopolitical resistance, measured with 500 v megohmmeter. The resistance value should not be less than 1 megohm. Bearing is widely used in all kinds of industrial equipment and precision instruments, combined with the above, the bearing shell cleaning and inspection, cleaning and inspection of the bearing, bearing flange structure is very important, understand the main shaft bearing the points for attention during the installation, hope to help you, more information please click: main shaft bearing and how to correct preload configuration high speed spindle bearing in the process of nc machine tools spindle bearing temperature detecting spindle technology requirements for bearing tags: spindle bearing installed
