In recent years, with the rapid development of China's technology, many industries have the original manual manufacturing to machinery manufacturing transformation, industrial robots are playing an important role in this, bearings as an important key components of industrial robots, in the selection of the type has all the right factors conditions, the appropriate matching bearings can greatly improve the efficiency of the robot. Today we will talk to you about the factors that should be considered when choosing a robot bearing

1、Bearing type

Bearing type is generally selected by the user's technical personnel according to the conditions of use of the supporting products and bearing load on the bearing. Sales staff mainly understand whether the actual load of the user is in line with the selected bearing, if the bearing can not meet the requirements of use, the customer should be recommended as soon as possible to change the model, but unless special products in the selection of the model will generally not have any problems.

2, bearing load size and direction

Load is an important factor when choosing bearings. According to the size of the load to choose the type of bearing, due to the roller bearing between the main components is a line contact, suitable for bearing larger loads, bearing after the deformation is also smaller. And ball bearing is point contact, should be used to bear light or medium load, so in the load is small, should give priority to the ball bearing.

In the load direction, when bearing pure radial load, can use deep groove ball bearings, cylindrical roller bearings or needle roller bearings. Thrust ball bearings can be used for smaller pure axial load, thrust roller bearings can be used for larger pure axial load. When the bearing is radial and axial combined load, usually use angular contact ball bearings or tapered roller bearings.

3、Bearing clearance

Users in the purchase of bearings will generally only inform in what model, grade, rarely will the bearing clearance requirements, need to understand clearly the use of bearing conditions, which bearing speed, temperature, with tolerance are directly related to the choice of bearing clearance.

4、Grease

The choice of grease is generally based on the bearing speed, temperature resistance, noise requirements and starting torque and other aspects of the choice.

5, bearing seal type

Seal parts contact sealing and non-contact sealing two, contact sealing dustproof performance is good but the starting torque is large, non-contact sealing starting torque is small, but the sealing performance is not contact good.

6、Bearing quality

Whether the robot bearing can achieve a good use of the effect, should certainly still take into account the overall quality of how, so that we can really see a good use of the effect. After all, the scope of application of the robot is still very wide, so it should certainly still do a good job of overall confirmation, must ensure that the quality of the bearing situation, as far as possible is directly selected to the big brand bearings, so that the use of the effect to be better, but also to ensure long-term use, a high safety factor, practicality is more secure to us.

7, bearing easy to install and remove

This is also a factor that should be considered when choosing the type of bearing. In the bearing seat without a split surface and must be installed and dismantled along the axial bearing parts, should be preferred to the inner and outer ring can be separated bearings.

The above is a detailed explanation of the factors that should be considered when choosing robot bearings, the purchase of robot bearings must do a good job of measuring the overall work, especially the model and quality factors can not be ignored, only then can be to ensure that the future work of the robot more safe and stable operation.
