DC Right Angle Worm reducers for heavy load design.
DC Right Angle Worm reducers for heavy load design.

The worm gearboxes are the oldest flexible types of gear reducers and the type also named orthogonal gear reducer is the ideal selection for changing direction by 90 degrees.
Worm gears are widely used in industrial, heavy machinery and even consumer applications. Despite its relatively low efficiency, it can provide a high reduction rate and is usually self-locking. The self-locking feature makes it very suitable for lifting and lifting applications. Also fast Braking and Stopping Applications makes the gear motors are commonly used in lifts, elevators, and hoists.
Worm gears also offer Space Saving Applications. Since worm gears are used in the manufacturing and packaging industries. They are used in packaging equipment, small machinery, and conveyors. They are ideal for these types of equipment because the feature of worm gear is having fewer gear sets which achieve high gear ratios. They require smaller gearboxes for these gear sets, making them a great space saver.

Over the years, we have introduced a wide array of worm geared products. Combined with DC Brushed, stepping or Brushless motor, it could be applicate in different area. Just like medical, food processing Opening Systems.
Speed from 60 to 400 RPM and Torque range: 1 - 150 Nm (10-1500 Kgcm)
NEMA flange acceptable.
Single Step ratio : 7.5 10 15 20 25 30 40 50 60 80 100
Double Step ratio from 100 up to 3600.
It's suit for very low speed like 1 rpm application.

Worm drive Worm gear
Worm-and-Wheel sets are typically comprised of a steel worm and a brass wheel (or bronze). A wide range of possible applications make worm gearboxes popular. Especially they have the great advantage of being easy to install and uninstall.
Brushed, stepping or Brushless combine
DC Brushed, stepping or Brushless Worm Geared Motor are high power could be applicant for Industrial Equipment, AGV, RGV, IGV, Golf Cart, Sweeper, Floor Cleaning Machine, UV-Disinfection Robot, Automatic lift chair, disable car or E-Scooter.
