Worm gears are found in industrial applications, heavy equipment, and even consumer applications.

Worm gears: What are they and where are they used?

Experimental investigations on different worm gears were conducted on several test rigs, taking into consideration the influence of different gear ratios, worm wheel materials, lubricants, and contact pattern on efficiency and load-carrying capacity. Recommendations for an increase in overall worm gearbox efficiencies are presented. Due to a wide range of properties, worm gears are an indispensable element on the current transmission market. Furthermore, worm gears provide the opportunity of self-locking, respectively self-braking. Despite these benefits, as a result of greater energy awareness, the efficiency of worm gears is in focus.

Worm Gears Explained

Care should be taken when selecting a Worm wheel reduction gearbox for a new application. There are many factors that can affect the service life of the unit. The correct selection must be made to ensure the efficiency of the reducer. Some of these factors including service, load, torque etc. Ratings shown are compiled using standard engineering procedures. Prototype testing of every application is recommended before production. Worm wheel reduction gearboxes are made in many styles and sizes.

A worm drive is a gear arrangement in which a worm which is a gear in the form of a screw meshes with a worm gear which is similar in appearance to a spur gear. The two elements are also called the worm screw and worm wheel. The terminology is often confused by imprecise use of the term worm gear to refer to the worm, the worm gear, or the worm drive as a unit. The worm gear or "endless screw" was invented by either Archytas of Terentum, Apollonius of Perge , or Archimedes , the last one the most probable author. Like other gear arrangements, a worm drive can reduce rotational speed or transmit higher torque. A worm is an example of a screw , one of the six simple machines. One of the major advantages of worm gear drive units are that they can transfer motion in 90 degrees.

Load Capacity of Worm Gears

They are also the smoothest, quietest form of gearing when properly applied. Boston Gear offers worm gears manufactured from a variety of materials, such as acetal, minlon, bronze, and cast iron to suit your application's requirements. Note: Because the efficiency of a worm gear drive depends on the lead angle and number of starts on the worm, the ratio should be kept low. To run properly, worms and worm gears operating together must have the same diametral pitch and threads.

What Is a Worm Gear?

Worm and Worm Gears sets transfer motion between non-intersecting right angle shafts. They are the most compact small precision gears system available, as well as the quietest and smoothest running. A worm and worm gears set can provide a high reduction ratio in a very small space. US has been manufacturing worm and wheel gear systems for over 30 years. We offer worms and worm gears sets in a variety of inch and metric sizes and with numerous pitch, tooth count, and hub options.
