How to install the slewing bearing?

Slewing bearing is a large bearing with a special structure that can withstand large axial loads, radial loads, and overturning moments simultaneously. It has the characteristics of compact structure, convenient guide rotation, and easy installation and maintenance.
Slewing bearing is a large bearing that can withstand comprehensive loads, and can simultaneously withstand large axial, radial loads, and overturning moments. Slewing bearing generally has installation holes, internal or external gears, lubricating oil holes, and sealing devices, which can make the host design compact, easy to guide, and easy to maintain.

Installation of slewing bearing

1. Apply lubricating grease to the slewing bearing

Gently and evenly apply appropriate lubricating grease on the raceway. Fill the gap between the roller and the isolation block. The number of rollers and isolation blocks is usually equal, and cylindrical cutting tools and isolation blocks should be close to each other. If there is a slight gap between the drum and the isolation block, the thickness of one or two isolation blocks can be adjusted to compensate for the gap.
2. Rotary bearing installation bolts
Tighten the two opposite assembly bolts along the diameter direction by 1-2 turns while rotating the other integral collar to prevent the roller from getting stuck in an inappropriate position. Then tighten the two symmetrical studs spaced 180 degrees apart, and so on, until all bolts are tightened to the specified torque value. When tightening the bolts, it is necessary to ensure that the adjustment plate is not misaligned and use a torque wrench to obtain the specified bolt pre tightening torque.
3. Inspection after installation of slewing bearing
If abnormal phenomena such as noise, impact, or sudden increase in power occur during installation and use, the machine should be shut down for inspection. After running for about 100 hours, check the pre tightening torque of the installation bolts on the inner and outer rings of the rotary table bearing. Afterwards, check every 500 hours of operation.
When disassembling and cleaning bearings, they should be assembled according to the bearing assembly drawing, and the upper and lower half rings should be assembled according to the original drilling positions. The surface of teeth should be cleaned of debris every 10 days and coated with lubricating grease.

Installation requirements for slewing bearings

Before fully tightening the installation bolts, a gear mesh check should be carried out to ensure that the backlash meets the accuracy requirements of the gear.

When installing bolts, tempered flat washers can be used, and spring washers are prohibited.
After the radial positioning of the rotary table bearing, cross tighten the installation bolts and check the free rotation of the bearing. When tightening bolts, there should be sufficient pre tightening force, which should be 70% of the yield limit of the bolt material.
Before fully tightening the installation bolts, gear meshing inspection should be carried out to ensure that the meshing clearance meets the accuracy requirements of the gear.
The above is an explanation of how to install the rotary table bearing and the process. When installing the rotary table bearing, it is necessary to do a good job in relevant work and clearly grasp the precautions during the installation process. As the turntable bearing is a large bearing, we should support it.

Application of slewing bearings

LTZC bearings are widely used in large rotating devices such as engineering machinery, mining machinery, wind power generation, ships, ports, petroleum, chemical, light industry, medical equipment, automobiles, robots, aerospace, radar, military, and so on. Today we will explain in detail the installation method of the rotary table bearing.
