Introduction and Types of Slewing Ring Gears

Ⅰ. Introduction of slewing ring gear


Slewing ring gear is a new type of mechanical component. It has inner and outer rings, rolling elements, etc. The slewing ring is a large bearing that can bear combined loads, and can bear larger axial, radial loads and overturning moments at the same time. Slewing bearings are widely used in actual industries. It is called the "joint of the machine". The slewing ring gear is a mechanical device that needs to perform relative rotational movement between two objects, and also needs to bear axial force, radial force and tilting moment. Important transmission components are required. With the rapid development of the machinery industry, slewing bearings have been widely used in marine equipment, engineering machinery, light industry machinery, metallurgical machinery, and medical machinery.


Ⅱ. Working method of slewing ring gear:


There are different working methods according to actual use and design structure of these kind of slewing drive distributors. There are two basic working methods:


1. The inner ring fixes its supporting function and the outer ring rotates


2. The outer ring fixes its supporting function and the inner ring rotates


Ⅲ. Slewing ring gears can be divided into two categories


1. Single row ball slewing ring  gear


The single-row spherical slewing ring gear has four points and one row.


2. Double row ball slewing bearings


Slewing ring gears are widely used. Construction machinery is the first and most widely used place for slewing bearings, such as earthmoving machinery, excavators, disassembly machines, stackers and reclaimers, graders, road rollers, dynamic compactors, rock drilling machines, roadheaders.
