Analysis on the personalized development of slewing bearings

2020-09-22

With the continuous development of construction machinery, according to the individual needs of users, construction machinery is moving in a personalized direction. For example, excavators include large, medium and small excavators, as well as various types of excavators for special purposes. Therefore, requirements are put forward for the personalized development of slewing bearings. Today, I mainly talk about the personalized development of slewing bearings.

1. The individualized development of different scales, because the size and model of various construction machinery are inconsistent, it also needs a suitable slewing bearing scale.

2. Special purpose slewing bearings, such as the maximum bearing capacity, follow the development of construction machinery and are developing towards large-scale development. Some construction machinery has hundreds of tons, so the maximum bearing capacity of slewing bearings is continuously increasing.

3. With the requirements of different temperatures, the use environment of machinery is constantly expanding. The total high temperature, high humidity and high salt environment and the cold environment require the exhibition center to adapt.

4. The requirement for low failure rate, with the development of aerospace technology, requires the slewing ring to have the characteristics of ultra-low failure rate.

Slewing bearings are delicate equipment, so small differences may affect the normal use of slewing bearings, and the temperature is also the case. The general slewing bearing temperature can be used normally at -200 and 1000 degrees. It is assumed that the slewing bearing of special steel is not required at this scale, such as the special purpose slewing bearing with low temperature and high temperature resistance. For example, slewing bearings used in harsh conditions, such as corrosion resistance, salt and alkali resistance, etc., require special corrosion resistance materials.

In summary, with the development of construction machinery, new requirements are put forward for slewing bearings. The development of individualized construction machinery requires the corresponding personalized development of slewing bearings to meet the needs of construction machinery and is also the personalized development of slewing bearings. Driving force and certain development.
