RV Series Special Bearing For Industrial Robots

The RV series is a well-known type of precision reducer used in industrial robotics, especially in applications that require high rigidity, load-bearing capability, and precise control. RV reducers are commonly used in robotic arms and other high-performance automation systems where heavy loads, accuracy, and minimal backlash are essential. At the heart of these reducers are the special bearings that play a critical role in supporting the unique structure and performance of the RV series.

Product Details

The RV Reducer is designed with a large number of engaged gears, which gives it the characteristics of small-scale lightweight, high rigidity, and overload resistance. Furthermore, the absence of clearance, small rotation vibration and inertia allows for excellent acceleration performance, ensuring smooth operation and accurate positioning.

The precision installation and machining accuracy of the various parts are the key factors that contribute to the superior performance of the RV Reducer. The entire reducer is assembled using a preloading method, which necessitates the highest level of precision in all reducer components and an equally high standard for the internal bearing. The bearing's shape, structure, and precise positioning are compact, rigid, and precise. The key factors of the bearing are large output torque, high precision, large load capacity, small volume, high rigidity, low noise, long life, stable operation, and high reliability. When installing two matched main support bearings, it is necessary to adjust the axial preloading of the bearing. Please contact our technical personnel for the specific preloading value of the bearing.
Based on the advantages of RV Reducer, it is widely used in industrial robots, machine tools, aerospace, and other industries.

Features of Rotary Table Bearings

1. High Rigidity and Load Capacity: The bearings used in RV reducers offer high rigidity, which supports large loads and absorbs vibrations during operation. This is critical for industrial robots that perform repetitive, high-torque tasks.

2. Minimal Backlash: RV reducers, with their specialized bearings, exhibit very low backlash, which is essential for precise motion control in robotics.

3. Compact and Lightweight Design: RV bearings allow the gearbox to be compact while maintaining high load capacity, which is crucial for robotics where space and weight constraints are often priorities.

4. Long Service Life: Bearings in RV reducers are designed for durability, with high wear resistance and longevity, even in continuous operation.

5. High Precision and Smooth Operation: The bearings ensure smooth, accurate rotation with minimal friction, improving the efficiency of robotic movement and reducing heat generation.

What Is Spur Gear Slew Drive

Spur gear slewing drive is composed of slewing bearings, gears, housings, adapter flanges, support bearings, seals and other components. After reasonable design, component manufacturing, debugging, assembly and other processes, the products have the ability to withstand axial force, radial force, tilting moment torque and at the same time has a certain gear ratio, referred to as slewing drive.

DEMONSTRATION OF THE APPLICATION OF SLEW DRIVE



Easy to use: The use of our products needs only 3 steps.   1.The shell and inner ring of the swing drive are connected to the base flange.    2. Install the motor.    3. Connect the equipment to be rotated to the outer ring of the slewing gear bearing.
 
 

CLASSIFICATION AND CODE DESCRIPTION

VK CLASSIFICATION AND CODE DESCRIPTION

Spur gear slewing drives are divided into 3 series according to different modules, light load M=4, medium load M=6, heavy load M=8. The total height of the slewing drive is also corresponds to low, medium and high respectively.
 
The size of each series is from small to large and the load and tilting moment torque are also gradually increasing to meet various requirements of customers.
We can quickly select models according to customer requirements. After initial communication, if necessary, we can quickly customize non-standard slewing drives for customers.
 

MODEL SELECTION

SLEWING DRIVE MODEL SELECTION
 
VK-Transmission can provide a clear selection verification document to customers, then customers can clearly figure out whether the slewing drive is suitable, intuitively understand the safety factor of each parameter to avoid the trouble and loss caused by selection error.
