2, bearing equipment and disassembly; in the specific application occasions often need to open and equipment; to ensure that it can be tested and repaired according to its location. The inner and outer ring can separate the bearing of the equipment such as: cylindrical bearing; needle bearing; and tapered bearing Very suitable for this occasion. The tapered self-aligning ball bearing and the active spherical roller bearing are assisted by the bushing; the same simplifies the equipment program.
3. In some cases, the rolling bearing should be pre-stressed to add rigidity; this procedure is generally used for deep groove ball bearings, radial thrust ball bearings and tapered roller bearings inner and outer ring offset; shaft tortuosity; shaft or bearing box public service Change; cooperation fault will lead to the pain of the inner and outer circle. To avoid excessive pain angles; active self-aligning ball bearings; active spherical roller bearings; or aligning bearing housing is the better choice. å—“ audio frequency and torque; Dynamic bearings are produced according to high-precision standards; therefore, the sound and torque are small. Deep groove ball bearings and cylindrical roller bearings are used in combination with low noise and low torque.
4, the standard IKO bearing standard way is complicated; the best choice of standard bearings in mechanical equipment design.
Its nature, size, and direction are variable. Generally; the extra fundamental load is shown on the standard table. But the axial load and radial load, etc.; is also an important factor in selecting the right bearing. When the ball and needle bearing When the standard is equal; needle bearings generally have a higher load and can accept large oscillation and shock loads.
5, bearing public service; bearing standard accuracy and rotation accuracy is based on ISO and JIS standards. For high-precision and high-speed machining of the machine; advocate the use of 5 or more precision bearings; deep groove ball bearings, radial thrust ball bearings or Cylindrical roller bearings are used for high-precision mechanical and rigid; when the bearing's moving body and raceway contact surface are pressed; elastic deformation occurs. Some mechanical requirements minimize elastic deformation. Roller bearings occur more than ball bearings The elastic shape variable is small.
