When the female rod end is used, the sliding surface is spherical, and it can also be tilted within a certain angle range when it is used. When the support shaft and the shaft hole are not different, the normal operation can still be performed.
The female rod end can withstand a large load to a certain extent, and can be subjected to a combined load to the load, the axial load or the radial and axial directions when in use according to its different type and structure. Since the outer surface of the inner ring is provided with a composite material, the bearing can be self-lubricated during operation. Generally used for low-speed oscillating motion, and low-speed rotation, it can also be tilted within a certain angle range. When the support shaft and the shaft housing hole are different, the normal operation can still be performed. Self-lubricating joint bearings are used in water conservancy and professional machinery industries.
The female rod end has two "fit" spherical contact surfaces, which are referred to as coordinated contacts. The calculation method of mechanical properties of joint bearings plays an important role in the structural design and wear analysis of joint bearings. A spherical contact unified model can better solve the problem of small deformation spherical contact pressure distribution. This model is applicable to both non-coordinated contact and coordinated contact. However, the contact area of the joint bearing is not a complete spherical surface, and the calculation of the contact pressure distribution needs to be further calculated on the basis of the complete spherical coordinated contact model.www.wxjwbearing.com
