OFweek Robotics Network News: As one of the key components of industrial robots, industrial robot bearings are most suitable for joint or rotating parts of industrial robots, rotating workbenches in mechanical machining centers, rotating parts of robotic arms, precision rotating workbenches, medical instruments, measuring instruments, IC manufacturing devices, and a wide range of applications. There are mainly two types of bearings used for industrial robots, one is equal section thin-walled bearings, and the other is cross cylindrical roller bearings. In addition, there are also harmonic reducer bearings, linear bearings, joint bearings, etc., but mainly the first two types of bearings.

Characteristics of industrial robot bearings: 1. Can withstand comprehensive loads in axial, radial, and overturning directions; 2. Thin walled bearings; 3. High rotational positioning accuracy. Any bearing that can meet this design requirement can be used in industrial robot arms, rotary joints, chassis, and other parts.

Classification of industrial robot bearings:

1、 Cross roller bearing

The characteristics of cross roller bearings: Cross roller bearings are cylindrical or tapered rollers arranged perpendicular to each other through isolation blocks on a 90 degree V-shaped groove rolling surface. Therefore, cross roller bearings can withstand multi-directional loads such as radial loads, axial loads, and torque loads. The size of the inner and outer rings has been miniaturized, and the ultra-thin form is closer to the limit of small size, with high rigidity and accuracy up to P5, P4, P2 levels. Therefore, it is suitable for the joint and rotating parts of industrial robots, rotating tables for machining centers, precision rotating workbenches, medical machines, calculators, military industry, IC manufacturing devices, and other equipment.

1. Has excellent rotational accuracy:

The internal structure of the cross roller bearing adopts rollers arranged in a 90 ° perpendicular to each other, with spacing retainers or isolation blocks installed between the rollers to prevent tilting and mutual friction between the rollers, effectively preventing an increase in rotational torque. In addition, there will be no contact or locking of the roller on one side; Meanwhile, due to the segmented structure of the inner and outer rings, the gap can be adjusted, allowing for high-precision rotational motion even when preloading is applied.

2. Simplified operation and installation:

The outer or inner ring, which is divided into two parts, is fixed together after installing the rollers and retainers, so the installation process is very simple.

3. Withstand significant axial and radial loads:

Because the rollers are arranged perpendicular to each other through spacer retainers on a 90 ° V-groove rolling surface, this design allows the cross roller bearing to withstand large radial, axial, and torque loads in all directions
