Worm Reducer

The worm gear reducer, a traditional transmission device, consists of a worm gear and a worm with an involute tooth profile. Its advantages include a compact mechanical structure, lightweight design, and small size, as well as efficient heat dissipation, easy installation, and maintenance. It offers a high transmission ratio and torque capacity, ensuring smooth operation with low noise. Additionally, the worm gear reducer is known for its durability and versatility, making it suitable for lifting operations. It has a long service life and accommodates a wide range of input speeds for significant speed reduction. Moreover, it features a self-locking capability.

However, a drawback of the worm gear reducer is its relatively low working efficiency, which typically reaches only below 60%.
Additionally, controlling backlash can be challenging, especially after prolonged engagement between the worm gear and the worm, resulting in significant play.

The worm gear in our selected reducer is made of 12-2 tin bronze, which is of the highest quality standard among our peers.
Many others only use ordinary bronze, with the slightly better option being 10-1 tin bronze.
The choice of tin bronze was made due to two reasons: first, bronze acts as a lubricant, reducing friction, and second, bronze has a softer texture compared to the worm, which is typically harder.
As the worm is the driving wheel and connected to the motor, in case of equipment failure preventing rotation, the worm gear can be sacrificed to protect the motor from damage and allow it to continue operating.

The accuracy level of the worm is between 4 and 8, and it is made of high-density alloy steel, ensuring minimal wear.

The input end seal is a renowned Chinese SKF oil seal, greatly reducing the risk of oil leakage.

Our selected gear reducer represents the top-quality level in China.
