Single-row four-point contact ball slewing ring (01 series)-internal gear

Structural features, performance, scope of application

The presentation of slewing bearing products is mainly to provide you with a better extension of the life of the machine. Because we know that the role of support in the machine is irreplaceable, if the support of a machine is broken, then it will not continue Work, as long as the support is replaced, it can continue to resume production.

If the slewing bearing frequently carries heavy objects, it may be difficult to rotate or even unable to rotate. The reason for this phenomenon is that the larger the crane tonnage, the larger the diameter of the slewing ring and the lower the manufacturing accuracy. , Its safety factor is actually lower, so it is more prone to damage. It is possible to appropriately increase the thickness of the plate at the connecting part of the turntable and the slewing ring, and then improve the structural rigidity of the slewing ring, and then improve its bearing capacity.

Single-row four-point contact ballSlewing ringComposed of two seat rings, compact structure, light weight, four-point contact between the steel ball and the arc raceway.

Note:

1. The mounting holes n-dn1 and n-dn2 can be changed to screw holes; the tooth width b can be changed to Hh.

2. The gear circumferential force in the table is a large circumferential force, and the extra circumferential force is 1/2.

3. The internal tooth trimming coefficient is 0.2.
