The structure characteristics of tapered roller bearing manufacturing is introduced

The structure characteristics of tapered roller bearing manufacturing introduce source: bearing | last updated: - 2020 06 - 23 introduce the structure characteristics of tapered roller bearing manufacturing cage is used to separate isometric roller, and prevent falling into the roller bearings rolling bearing, guide and drive roller rotation. Rolling bearing cage can be divided into punching cage and solid cage. Rolling bearing in the work, can produce heat because of sliding friction and wear, especially in the case of high speed, due to the effect of centrifugal force, will aggravate the friction and wear and heat, serious will aggravate the wear. Lead to keep burning and rupture, resulting in bearing failure. Adopted. Cage damage accounted for most of bearing failure modes. In damage to the cause of the cage, the cage material quality is one of the main reasons. Therefore, the requirement of bearing roller bearing cage materials must have the following features: 1. Cage has a fixed strength and toughness, can withstand a certain load and impact, and it has good elasticity and rigidity. 2, and the rolling body small friction coefficient, good wear resistance. 3. Must have good thermal conductivity. 4. The proportion of small, expansion coefficient is similar to the rolling body. 5. Due to keep the frame structure is usually more complex, so request, has a good processing performance of materials. 6. Stamping molding cage material need good plasticity and ductility. 7. Rotating cage material need good cutting performance. 8. Die-casting frame material requirements a good casting performance. 9. Injection molding frame material requirements a good injection performance. The structure characteristics of bearing tapered roller bearing is introduced wholesale bearings. Structure characteristics of tapered roller bearing. Tapered roller bearing type code is 30000. Tapered roller bearings are separate bearings. Under normal circumstances, especially in GB/T307. 1 - 94 'rolling bearing radial bearing tolerance' involved in the scope of the size of the tapered roller bearing outer ring and can be completely interchangeable between internal components. The Angle of the outer ring and the diameter of the outer raceway normalized to external dimensions. During the design and manufacture are not allowed to change. Therefore, tapered roller bearing outer ring and the internal components can swap on a global scale. Tapered roller bearing is mainly used to inherit the combination of radial and axial load, mainly radial load. Compared with the angular contact ball bearing, bearing capacity and limit rotational speed is low. Tapered roller bearing can be carry axial load in one direction, and can limit shaft or in a direction and the axial displacement of the bearing.
