WPKS80-20 worm gear reducer is a medium-sized specification in the WP series (center distance 80mm, transmission ratio 20). Combined with its structural design and performance characteristics, it has many significant advantages in small and medium-power transmission scenarios, as follows:
1. Advantages of transmission characteristics: adaptable to efficient deceleration requirements of small and medium loads
Large transmission ratio realized in single stage
The transmission ratio of 20 belongs to the medium to large range. Reduction can be completed through single-stage worm gear meshing (no need for multi-stage gear combination). Compared with multi-stage gear reducers, it has a more compact structure and smaller size (especially short axial size). It is suitable for scenarios with limited installation space (such as small production lines and side transmission of equipment).
Stable output torque
When the center distance of 80mm is designed to match the transmission ratio of 20, at an input speed of 1500r/min, the output torque can reach 80-120N·m (depending on the input power). It can stably drive small and medium-load equipment (such as small conveyor belts, mixing devices), and the worm gear meshing is line contact. The smoothness of the transmission is better than the point contact of the gear, and the operating noise is low (usually ≤75dB).
Reverse self-locking function
When the worm lead angle is smaller than the friction angle of the meshing surface, reverse self-locking can be achieved (the worm wheel cannot drive the worm to rotate). In lifting equipment (such as small elevators and hopper lifting), it can prevent the load from sliding under its own weight and improve operational safety without the need for additional braking devices.
2. Structural design advantages: adapt to diverse installation and maintenance needs
Modular installation flexibility
The WPKS series adopts the 'K' type installation form (usually hollow shaft output, with keyway or shrink disk), which can be directly connected to the motor and working machine through couplings or flanges. It is suitable for various installation directions such as horizontal and vertical, and can be quickly integrated into various equipment production lines.
The box has strong sealing performance
The box body is cast from gray cast iron (HT200), with uniform wall thickness and good rigidity. The joint surface is precision machined and equipped with sealing strips. The input/output shaft ends adopt skeleton oil seals, which can effectively prevent lubricating oil leakage (especially in dusty and humid environments) and reduce maintenance frequency.
Low maintenance cost
The internal structure is simple (mainly composed of worms, worm gears, and bearings), and the parts are highly versatile. No complicated tools are needed to replace wearing parts (such as bearings, oil seals); the lubrication method is oil bath lubrication, and daily maintenance only requires regular oil level checks and oil changes, and the operating threshold is low.
