Speed Reducers and Gearmotors

A speed reducer is a mechanical device that employs gears for the purpose of reducing the speed (RPM) and increasing the torque of a motor. Usually, a speed reducer is mounted or coupled to an electric motor. An indefinite number of speed reducer options are available depending on the application. They can be sourced based on desired configurations, ratios and combinations, efficiency requirements, space limitations, cost, and rpm. Today, speed reducers are utilized in all sorts of industries.

Variety of Speed Reducers and Gear Motors

Worm gear speed reducer
        It is a right angle speed reducer that provides maximum speed reduction in smallest package
        Used in low to moderate horsepower applications
        Low initial cost, high output torque and, high ratios in a small package
        Higher tolerance for shock loading
Bevel gearbox speed reducer
        It’s also a right angle speed reducer with relatively higher efficiency than the worm gear speed reducer
        Useful for applications that require a right angle speed reducer with a low ratio
Helical gear speed reducer
        Highly efficient and capable of handling higher overhung loads
        In-line helical gear speed reducers are less expensive than parallel shaft reducers
        Parallel shaft offers more flexibility and implementation options
        Used in applications requiring higher horsepower and long-term operational efficiency
        Comparatively higher initial cost
Planetary gear speed reducer
        Offers various advantages over traditional gearbox arrangements
        Compact, yet outstanding power transmission efficiency
        Lower efficiency losses per stage (as low as 3%)
        Great torque capability due to effective load distribution between multiple gears
        Greater stability and increased rotational stiffness
