Static Self-locking of Worm Gear Reducer
To Prevent Reverse Rotation
Static self locking is a critical characteristic of worm gearboxes, referring to the inability of the worm wheel to drive the worm in reverse when the system is at rest. Even under load, the system remains stably stationary. This property relies on the frictional forces within the transmission mechanism, as well as the design parameters and material properties. It effectively prevents reverse rotation or sliding caused by gravity or external forces when the equipment is shut down.
The static self locking characteristic of the worm gearbox developed and manufactured by Chen Yue (Jiangsu) Technology Co., Ltd. primarily derives from the unique geometric design and frictional resistance of the worm and worm wheel mechanism.
When the worm drives the worm wheel, power is transmitted through the helical structure of the worm to the worm wheel. However, in reverse, due to the friction angle of the worm wheel being greater than the reverse sliding angle, the worm wheel cannot drive the worm to rotate backward even under load. This phenomenon is the key to static self-locking.
Friction serves as the foundation of static self-locking. High-friction-coefficient materials—such as the proprietary tin-bronze alloy worm wheels and steel worms developed by the company—significantly enhance the static self-locking performance of the gearbox. Furthermore, the entire product range features a high transmission ratio, which minimizes the possibility of reverse driving from the worm wheel to the worm.
The worm gear reducers manufactured by Chen Yue (Jiangsu) Technology Co., Ltd. offer a distinct advantage of static self-locking. Under load, the equipment remains stable even when the motor is powered off, effectively preventing safety risks associated with reverse rotation. This feature allows the reducer to replace traditional braking devices, reducing system complexity and maintenance costs.
The company's reducers excel in load-holding applications, particularly in lifting equipment, hoisting systems, and precision positioning systems.
