The development of small slewing bearing and its problem analysis

How to completeSmall slewing bearingDoes the industry develop along with the development of industry? my country’s small slewing bearing industry has developed outstandingly in recent years, and the products developed are quite advanced. It has reached the advanced production level of foreign countries, although it still cannot compete with developed foreign regions. However, a lot of new value has been created. Why did this phenomenon occur? There are many reasons for the phenomenon that the development of my country's small turntable bearing industry is not as good as foreign advanced skills. To deal with this situation, it is necessary for developers to work on small turntables. Continuous innovation in the bearing industry.

At present, the ability of our independent research and development is still relatively weak. Although there are special research and development bases in some areas of our country, the research and development areas will not be concentrated, do not constitute a certain scale, and lack competition ability. We know that competition ability can make small There is a sense of crisis in the slewing bearing industry. If you want to occupy the "leading" position in China's small slewing bearing market, you need to research on new small slewing bearing products by relevant enterprise researchers. Due to the relatively low level of development of small slewing bearings in our country, there is no threat from the outside world, and many companies have ignored the effects of the competition.

So slowly began to slack off, resulting in the reduction of innovative talents and the inability of innovative products to go on the market, leading to the development of advanced skills that are not as good as foreign countries, and the gap is getting wider. Makes us far behind other regions. In order to complete the development of the small slewing bearing industry, it is necessary to innovate new skills, learn advanced foreign skills, generate industry competitions, and make enterprises nervous, so that they can better exert their innovative energy and generate better value for benefits.

During the use of small slewing bearings, the temperature is high and the bearings are simply damaged.

Reason analysis:

1. If the vibrating screen has just been bought, it must be a production process problem. If the vibrating screen has been used for a period of time, it depends on the rigidity and foundation of the bearing.

2. For the smooth system, check and maintain the bearings regularly.

3. The bearing clearance should be selected appropriately.

4. Is the bearing manufacturer qualified? Now vibrating screen manufacturers mainly use domestic bearings, and our factory uses SKF bearings.

5. Processing accuracy. Due to the lack of domestic machining accuracy, 3 sets of large clearance bearings are selected. The choice of this type of bearing is at the expense of increased noise.

6. Bearing cooperation and reasonable selection of bearing cooperation affect bearing heating and life.

7. The structure design is unreasonable.

8. The center of gravity error of the vibrating screen is too large.

9. Unreasonable smoothness, perhaps too much or too little oil.

10. Whether the bearing is installed correctly or not, and whether the tolerance cooperation is reasonable or not, is the relationship between heat generation. Brief analysis of the production process of small slewing bearings The basic production process of rolling bearings due to the type, structure, tolerance level, skill requirements, materials and batch sizes of rolling bearings, the basic production process is not exactly the same.
