Shaft Grounding Ring--The Expert Of Motor Bearing Protection

In today's industrial field, the motor is the power heart, and its performance stability and life span are directly related to the continuous operation of the production line. However, the current corrosion problem of motor bearings has always troubled many engineers. Fortunately, the emergence of shaft grounding rings ( it also called as conductive rings) provides a perfect solution to this problem.

1. Why is there current corrosion?

We know that during the operation of the motor, due to electromagnetic induction, inverter drive and other factors, voltage will be generated on the shaft. When the voltage accumulates to a certain extent, it will discharge through the bearing and cause electrical corrosion. This kind of electrical corrosion is like the processing of electric sparks, which silently damages the bearing, resulting in reduced motor efficiency, increased noise, and even premature scrapping. In order to solve this current corrosion problem, shaft grounding ring products are produced.

2. What is the manufacturing process of the shaft grounding rings?

The manufacturing process of the shaft grounding ring is very particular, and every step from material selection to processing and molding is strictly controlled. High-quality metal materials and carbon fiber composite materials are used to ensure that the conductive ring has excellent conductivity and mechanical strength. At the same time, advanced processing technology ensures the close fit between the conductive ring and the motor shaft to form a stable conductive path. Volsun applied for and obtained a patent for the manufacture of this product.

3. The advantages of the shaft grounding ring are mainly: Extended motor bearings life, Improved reliability and Reduced costs

a). Extend bearing life: The shaft grounding ring guides the shaft current to the ground through a low-impedance path, effectively preventing bearing electro-corrosion and significantly extending the service life of the bearing and motor.

b). Improve reliability: Reduce motor failures caused by bearing damage, ensure stable operation of equipment, and improve the reliability of the production line.

c). Reduce maintenance costs: Reduce the frequency of bearing replacement and maintenance workload, saving a lot of maintenance costs for enterprises.

4. Wide range of applications

The application scenarios of the conductive ring are very wide. Whether it is a variable frequency drive motor, a high-speed motor or a large motor, the conductive ring can play an excellent protective role. In addition, metal and carbon fiber composite conductive rings have also been widely used in high-end fields such as wind power generation, aerospace, and medical equipment due to their high performance and lightweight advantages.

5. Simple and convenient installation and maintenance

The installation of the shaft grounding ring is very simple. Just make sure it is in close contact with the shaft and connect the grounding system. Regularly check the wear of the shaft grounding ring and brush, replace them when necessary, and keep them clean and maintained to ensure the durability of the shaft grounding ring.

With the continuous advancement of carbon fiber technology, the performance of metal and carbon fiber composite conductive rings will be further improved. With greater breakthroughs in conductivity, wear resistance and lightweight, it is expected to replace traditional metal conductive rings in more fields and become an innovative pioneer in the industrial field.
