Mar 24, 2017 - Bonfiglioli Universal Worm Gear Motor - Design and Applications

Bonfiglioli gear motors give flexibility with a wide range of mounting options, motor interfaces, and shaft configurations, all of which are offered as standard. The helical-worm and the double-worm version, with or without the torque limiter, create an extremely versatile drive system.

Bonfiglioli universal worm gear motors are considered a milestone in several different industries worldwide due to their state-of-the-art technology, uncompromising quality, and affordability.

Bonfiglioli universal worm gear motors are available in different sizes and can also be customized as per industry requirements and specifications. These gear motors are highly efficient, incorporate sturdy construction, and offer hassle-free performance. The gear motors can be easily installed and do not require a lot of maintenance.

Worm Gear Motors Design

Worm gears motors are designed to achieve a high total gear ratio with a small number of gear sets. This results in the ability to reach high output torque and low output speeds. It also allows for the higher torque and lower speed to be attained in a smaller gear housing.

Reversing the direction of torque transmission with worm gear motors can be difficult. As a result, changing direction can create an emergency braking action, which is helpful for a number of applications, particularly lifting and hoisting.  

Bonfiglioli Universal Worm Gear Motor Features:

• Hollow shaft

• Sealed gear case

• Better motor protection

• Tapped holes closed with button plugs

• Plug-in Solid Output Shaft

• Torque Limiter as an Option

Universal Worm Gear Motor Applications

Universal worm gear motors are ideal for a wide range of industrial applications, including:

Fast braking or stopping: Backdriving, or reversing the direction of the gears, is difficult with worm gears. Stopping and holding can be possible without an external brake, or a smaller brake system can be used with the worm gear as an emergency braking system. Examples include hoists, elevators, and lifts. Worm gears should not be relied on as a sole method for braking.

Reducing noise: Applications where noise is a concern include airports, theaters, and elevators. The smooth sliding action between the worm gear’s teeth reduces noise and allows for quieter operation than most of other gear motors. Gear worms are made from dissimilar materials, which contributes to their quiet operation.

Smaller spaces: Universal worm gear motors are designed in a way that allows for fewer gear sets to be used in order to achieve the higher required gear ratios for increased torque and reduced speed when needed. With fewer gear sets, the result is a smaller gearbox. Applications where space is a concern, include conveyors, small machinery, and packaging equipment.

Shock loading: Universal gear motors are made up of different materials. In this type of gear motor, one of the gear sets is made of a softer metal, which allows it to easily absorb the energy from sudden shock loads. Examples of applications that require shock loading include rock crushers and other heavy duty machinery.
