In the process of engineering drawing, the simplified drawing method of bearing is very common. There are many types of bearings, and the simplified drawing methods of different types of bearings are different. Simplified drawing of deep groove ball bearings Deep Groove Ball Bearings (GB/T 276-1994) is the most common type of rolling bearing. The basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cages. Simplified drawing of angular contact ball bearings Angular contact ball bearings can bear radial and axial loads at the same time. Can work at higher speeds. The larger the contact angle, the higher the axial load carrying capacity. High-precision and high-speed bearings usually take a 15-degree contact angle. Simplified drawing of tapered roller bearings Tapered roller bearings are not just because the raceway has a certain taper, but the rollers must have a certain taper, and the vertebral vertices of the rollers and the inner and outer raceway vertices must be the same point and on the shaft. On the center line (similar to a bevel gear), otherwise the roller head and raceway will produce sliding friction due to the same angular velocity and different linear velocity when the bearing is moving, resulting in low bearing efficiency, heat generation and easy damage. Drawing method tapered roller bearings are usually separated type, that is, the tapered inner ring assembly composed of the inner ring with roller and cage assembly can be installed separately from the tapered outer ring (outer ring).Tapered roller bearings mainly bear the diameter of The combined load of radial and axial direction is the main direction.Simplified drawing method of self-aligning ball bearing Self-aligning ball bearing has two structures of cylindrical hole and conical hole, and the material of the cage is steel h, synthetic resin, etc. Its characteristic is that the outer ring rolling The track is spherical and has self-aligning properties, which can compensate for errors caused by misalignment and shaft deflection, but the relative inclination of its inner and outer rings should not exceed 3 degrees. Work at high speed. The larger the contact angle, the higher the axial load capacity. High-precision and high-speed bearings usually take a contact angle of 15 degrees. Under the action of axial 8, the contact angle will increase. Simplified drawing of double row thrust ball bearings French row thrust ball bearing (50000, 5000U). Double row radial thrust ball bearing is a structure in which the back surfaces of the outer rings of two single row radial thrust ball bearings are matched, and the inner ring and the outer ring are integrated. Therefore, this Bearings with this structure have thrust load capacity in two directions. Therefore, double row thrust ball bearings are also called bidirectional thrust ball bearings.
