Worm gear reducer is a power transmission mechanism that uses the speed converter of gears to reduce the rotation of the motor to the desired rotation and obtain a large torque in the process.
1、 Basic principles
Worm gear reducer achieves the effect of reducing speed and increasing torque through the meshing transmission of worm gear and worm wheel. Worm is an active component with a shape similar to a screw, usually connected to the motor shaft; The worm gear is a driven component, shaped as a ring gear, and meshes with the worm. When the worm rotates, the meshing transmission between the worm and the worm wheel causes the worm wheel to rotate at a slower speed and output a larger torque.
2、 Main features
Compact structure: The volume of the worm gear reducer is relatively small, the structure is compact, and it is easy to install and use.
Large transmission ratio: Due to the large difference in the number of teeth between the worm and worm gear, a larger transmission ratio can be achieved.
Self locking function: Under certain conditions, the worm gear reducer has a self-locking function, which means that when the power source stops working, the output shaft will not rotate on its own.
Smooth transmission: The meshing process of worm gear transmission is smooth, with minimal vibration and noise.
High load-bearing capacity: Worm gear reducers have a high load-bearing capacity and are suitable for heavy-duty conditions.
3、 Classification
There are various types of worm gear reducers, and common classification methods include:
Classified by structural form: such as planar enveloping toroidal worm reducer, circular arc cylindrical worm reducer, two-stage worm and gear worm reducer, etc.
Classified by material: such as aluminum alloy worm gear reducer, cast iron worm gear reducer, etc.
Classified by series: such as WP series, WH series, CW series, RV series, etc.
4、 Application Fields
Worm gear reducers are widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical, textile, printing and dyeing, pharmaceuticals and other fields. In various types of mechanical equipment, worm gear reducers play an important role in reducing speed and increasing torque.
