What is the core turning component of the spur gear slewing drive?

Publish time:2021/07/02 News Views:93

At present, the core slewing component of the spur gear slewing drive is the slewing ring, which is a new type of mechanical component. It consists of an inner ring, an outer ring and rolling elements. The slewing ring is a large size bearing that can withstand comprehensive loads, at the same time bear large axial loads, radial loads and tilting moments.

 

The slewing bearings have two different working methods according to the actual use and design structure: 1. The inner ring is fixed for support and the outer ring rotates; 2. The outer ring is fixed for support and the inner ring rotates. Our gear type slewing drive is also divided into external gear type slewing drive and internal gear type slewing drive. While the rotating component of the spur gear slewing drive uses a single row four point contact ball slewing ring, but the precision type spur gear slewing drives and also require greater load capacity use single row crossed cylindrical roller slewing rings.

 

The following introduces the structure and use of two kinds of slewing bearings:

 

Single row four point contact ball slewing ring:

Single row four point contact ball slewing bearing consists of two rings, compact structure, steel balls are in contact with the peach-shaped raceway at four points, it’s mainly used for machinery that bears tilting moment, axial force and radial force, such as truck cranes, engineering work vehicles, tower cranes, excavators, pile drivers, radar scanning equipment, etc.

 

Single row crossed cylindrical roller slewing ring:

The single row crossed cylindrical roller slewing ring is composed of two rings, it has compact structure, high manufacturing precision, small clearance and high requirements for the accuracy of the installation foundation, the rollers are arranged in a 90° cross, it can bear axial force, radial force and at the same time can bear tilting moment, products are widely used in transportation, machinery and military products.

 

In addition, the slewing ring also has thin-walled, flanged, aluminum alloy and other light slewing bearings. The light slewing ring has the same structure as the ordinary slewing ring, with light weight and flexible rotation. It is widely used in food machinery, filling machinery, environmental protection machinery and other fields.
