In a Worm Gearbox, Worm Reduction Gear Box, Worm Speed Reducer, and Gear Motor Manufacturer, three to eleven gear teeth typically engage with the worm, depending on the ratio. The increased number of driven gear teeth in contact with the worm significantly boosts torque capacity and enhances shock load resistance. Additionally, by increasing the contact area on each gear tooth, the actual areas of instantaneous contact between the worm threads and the driven gear tooth form lines. These lines of contact move across the face of the gear tooth as it meshes with the worm. In double-enveloping worm gearing, the lines are configured to maximize power transmission and minimize stress on each gear tooth.

Working Conditions

Two shafts intersect at 90°. Input speed must not exceed 1500 rpm. The working environment temperature should range from 0°C to 40°C. When the temperature is below 0°C or above 40°C, lubricating oil should be pre-heated or cooled accordingly. The worm shafts can operate in reverse as well.

Advantages:
The SGR High Efficiency, Low Noise Cone Worm Series Worm Gearbox design offers remarkable advantages. First, the total load is distributed among more individual gear teeth, and the load is further divided where teeth support two lines of contact, greatly increasing load-carrying capacity. Second, the improved torque throughput allows a smaller reducer to produce the same amount of torque, leading to size and weight savings.
Double-enveloping worm gearing can handle loads that would otherwise require much larger and heavier cylindrical worm gearing.
