How to connect the motor to the rotary joint

Rotary joints are widely used in automation equipment, fixtures, construction machinery, aerospace, military radar, photovoltaic wind power, and many other applications. They can transmit mixed media such as gas, liquid, and electricity, and are a key rotary joint in equipment. As the saying goes, they are also an important adapter for equipment. We should choose professional rotary joint manufacturers to purchase products that are suitable for ourselves, because if a rotary joint fails in the equipment, the equipment will be completely “paralyzed”. There is a special type of rotary joint commonly used to connect with motors, with the front end connected to a chuck and the rear end connected to the motor spindle. Let’s specifically talk about how to connect with the motor.

There are two air holes on the rotor of the rotary joint and two air holes on the stator. The rotor part extends out of the stator part according to the size of the motor spindle, which ensures that the rotor part is effectively connected to the motor spindle through a flexible coupling. The reason for adding a coupling in the middle is to avoid deviation between the spindle of the rotary joint and the motor spindle due to installation inconsistency, and to avoid eccentric friction and product damage. The green part of the outer sleeve is fixed on the stationary part of the equipment, and the flange and pneumatic chuck are connected. The air holes on the side of the flange are connected to the two air holes of the pneumatic gripper, which are connected one in and one out to ensure the clamping and releasing action of the chuck. The speed of the rotary joint is determined by the motor speed and changes with the motor speed. The internal part adopts High speed bearing support, It ensures the smooth rotation of the entire rotor and is a product with high lifespan, excellent performance, and strong rigidity. The inlet gas source is connected to the blue jacket, providing gas power for the entire device. The key to this product lies in the rigidity and processing technology of the shaft. If the rigidity is too strong, it will break when subjected to excessive torque, and if the rigidity is too soft, it will be easy to wear. Therefore, the focus of this rotary joint product is on the processing and material selection of the shaft. That’s all for today’s discussion. In the next section, we will talk about the principle and structure of hydraulic slip rings
