What’s the reason of cross roller bearing temperature raise?

cross roller bearings

CROSSED ROLLER BEARINGS

Cross cylindrical roller bearing high temperature is a common fault of rotating equipment, which will reduce the bearing service life and increase the maintenance cost. When the temperature rises fast and the temperature exceeds the standard, it is easy to cause unplanned shutdown or load reduction of the unit, which has a great impact on economic benefits.Therefore, it is the guarantee of the continuous safe operation of the equipment to quickly determine the cause of the fault and take proper measures to solve it.

The reasons for cross cylindrical roller bearings temperature rise are as follows:

First: Does the quality of the lubricant deteriorate?If the lubricating oil viscosity is large, the precision cross roller bearing temperature will increase.

What causes the cross roller bearing fault vibration?

cross roller bearings

CROSSED ROLLER BEARINGS

The cross roller bearing fault vibration fault vibration is mainly caused by the following reasons:

1) Excessive load causes excessive deformation of inner and outer rings and rolling body, resulting in vibration – transmission vibration caused by the change of center of rotary axis of cross roller bearing with rolling body position, as well as vibration caused by inaccurate installation or different sizes of rolling body. Generally, such vibration is of low frequency.

2) Nonlinear vibration due to poor lubrication of grease.

What’s the attention when replace,install and maintain slewing bearings?

Large slewing bearing

LARGE SLEWING RING

The excellent performance of slewing bearings is the equipment which can bear hundreds of tons, thousands of tons and even tons. They are able to operate smoothly, with axial and radial loads as well as extremely large impact loads and overturning moments. It is a unique skill of slewing ring bearings.

With the continuous improvement of design and technology and the accumulation of manufacturing experience, our product quality has reached or approached the international advanced level.However, as the user fails to pay attention to the transportation, storage, installation and maintenance of rotary supports, the phenomenon of the host performance degradation cannot be ignored.The common slewing ring of bucket turbine bearing is inclined, the noise of stack-reclaimer bearing is harsh, the large crawler type equipment has the sound of slewing ring during the test run, and the rotation is not smooth.

What’s the slewing bearing performance and characteristics?

Slewing bearings

SLEWING RING BEARINGS

Slewing ring bearing is a kind of large bearing which can bear the combined load of large axial load, radial load and overturning moment at the same time.Generally, the swing bearing itself is equipped with mounting holes, lubricating oil and sealing devices, which can meet the different demands of various hosts working under various working conditions.On the other hand, the turntable bearing itself has the compact structure characteristics, easy to guide rotation, simple installation and easy maintenance, which is widely used in large slewing ring such as lifting transport machinery, extractors, construction machinery, port machinery, wind power generation, medical equipment, radar and missile launcher.

Swing ring usually consists of four parts, including inner ring, outer ring, rolling body and isolation block.As the core part adopts slewing bearing, it can bear axial force and radial force at the same time.It has many forms, but its structure is basically the same.
