TIMKEN slewing bearing FAQS

QWhat's the significance of slewing bearing' shift gear ?

A(1) avoid undercutting. Cutting gear with Z < Zmin without undercutting; (2) match the center distance. A pair of gears can not only be installed under the condition of non-standard center distance, but also meet the requirements of zero side clearance and standard top clearance. (3) improving the strength and meshing characteristics of the pinion can improve the bearing capacity of the gear mechanism. (4) repair the worn old gear.

QWhat's the shortcomings of slewing bearing' standard gear ?

AGenerally, gears with the number of teeth Z < Zmin cannot be used; It is not suitable for the case of center distance a; When a pair of standard gears are meshed with each other, the curvature radius and root thickness of the involute of the pinion profile are smaller, the meshing times are more, and the strength is lower.

QWhat is the characteristics of single row four point contact ball slewing bearing?

AThe single row four point contact ball type slewing bearing is composed of two seat rings. It has compact structure, light weight, four point contact between steel ball and arc raceway, and can bear axial force, radial force and overturning moment at the same time. Rotary conveyor, welding operator, small and medium-sized crane, excavator and other construction machinery can be selected.

QWhat is the scope of application of single row cross roller type slewing ring?

ASingle row cross roller slewing bearing is composed of two seat rings. It is compact in structure, light in weight, high in manufacturing accuracy, small in assembly clearance and high in installation accuracy. The rollers are arranged in 1:1 cross arrangement and can bear axial force, overturning moment and larger radial force at the same time. It is widely used in lifting and transportation, engineering machinery and military products.
