Worm gearboxes

Types and applications of worm gearboxes

Worm gear is a transmission mechanism for reducing angular velocity and increasing torque. The devices are manufactured in accordance with GOST 27701-88. In our store you can buy worm gearboxes of the following types:

• Single-stage with a range of gear ratios according to GOST 2144 from 5 to 100;
• Two-stage with a range of gear ratios according to GOST 2144 from 80 to 4000.

The number of revolutions of the input shaft does not exceed 1800 rpm. In some cases, if there is a technical justification, it is permissible to increase the rotation speed to 3000 rpm if the sliding speed of the worm gear is not more than 10 m/s.

Worm gearboxes presented in the catalog are widely used in mechanical engineering, aircraft engineering, machine tool construction and other industries. The device provides stable conversion of angular velocity and torque parameters. The mechanism is designed for uniform loads. You can buy a worm gear reducer from us for use in conveyors, conveyor belts, pumping equipment, electric gate drives, ventilation systems, climatic equipment, lifting mechanisms, concrete mixers.

The principle of operation of the worm gear

The operation of the worm gear is based on the coupling of teeth located on the shaft and a wheel with oblique teeth. When the shaft (worm) rotates, its teeth move along the axis. In this case, the teeth of the wheel move in the same direction. The axes of the worm and the wheel are located at an angle of 90 degrees relative to each other. The distance between them is shown in the marking.

Advantages and features of the worm gear

Two-stage and single-stage worm gearboxes have the following advantages:

• Implementation of large transfer ratios;
• Smooth engagement and minimum noise level;
• Lack of reverse motion transmission;
• Compact size and space saving;
• High kinematic accuracy;
• The average efficiency is 58%.

The mechanism is not recommended for use with capacities over 60 kW. The device requires efficient cooling using fans, forced circulation systems, etc.
