Embodiment Construction
[0025] Specific embodiments of the present invention are described with reference to the accompanying drawings.
[0026] as attached figure 1 Shown: its parts of bearing of the present invention comprise: outer ring 1, inner ring 2, steel ball 3, cage 4, retaining ring 5, sealing ring 6, screw 7.
[0027] The contact angle α and α1 of the bearing are designed to be 45°. The design of this angle is to enable the bearing to bear high combined axial and radial loads and large overturning moment at the same time; the bearing adopts negative clearance and has good rigidity The load carrying capacity of the bearing can be improved, and the use of negative clearance can also make the bearing run smoothly; the structure guided by rolling elements reduces the contact area and reduces the noise and heat generated by friction.
[0028] as attached figure 2 , image 3 As shown: the inner wall of the outer ring 1 is provided with an outer ring raceway 8, and the outer ring raceway 8 c...
