The working principle and function of external tooth turntable bearing

/in /by

The external tooth rotor bearing is an important mechanical element that includes the outer ring, the inner ring, the rolling body, and the holder. The bearing space is formed between the outer ring and the inner ring, while the rolling body is filled with this space, usually a sphere or a roller. The role of maintaining the frame is to fix the position of the rolling body to ensure that its relative position is stable. This simple and effective design provides a reliable structural basis for the external tooth rotor bearings. The specific work principle of the specific external tooth turntable bearing is explained in detail.

1. The working principle of the outer tooth turntable bearing

1. Rolling friction mechanism

The working principle of the external tooth rotor bearing mainly depends on the mechanism of rolling friction. When the external force acts on one of the inner and outer ring, the rolling body begins to roll between them instead of sliding. This rolling friction method effectively reduces the friction in the bearings and improves the efficiency of the bearings. In this way, the outer tooth rotor bearing can maintain a relatively low friction coefficient under high -speed rotation, reducing energy loss.

2. Sliding friction

The working principle of the external tooth rotor bearing also includes the adaptability of sliding friction. When the bearing is at a low speed or stopped state, the rolling body may switch to the sliding friction mode. In this case, the rolling body slides along the surface of the inner ring or the outer ring to produce friction. However, through the use of lubricants, sliding friction can still be effectively controlled to reduce energy loss and prolong the life of the bearings. Lubricants play a key role in maintaining the normal operation of the outer tooth rotor bearing.

This bearing structure is simple and reliable, making it a key component in the mechanical system. In engineering design, external tooth rotor bearing is often used to support rotating components, such as turntables, wheels, robotic arms, etc.

In the automotive industry, the external tooth rotor bearing is widely used in the wheel bearing system, providing a stable driving and reliable control to the vehicle. In addition, it also plays a key role in high -demand fields such as wind power generation and aerospace equipment.

In general, the working principle of the outer tooth rotor bearing is cleverly used by the method of rolling friction and sliding friction to realize the support and transfer load under various operating conditions. This makes it one of the indispensable key components in modern mechanical systems.
