Where are gearboxes used?

Advancements in technology and the evolution of gears have made more efficient and powerful gearboxes to be developed and manufactured at lower costs. Toothed gear systems have evolved from fixed axis gear systems to new and improved gears including helical, cycloid, spur, worm and planetary gear systems. Gearboxes are widely used in applications that require desired output speed (RPM), … Continue reading Where are gearboxes used?

How to Select the Appropriate Gearbox ?

Gear arrangement is an ingenious engineering design that offers various benefits over the traditional fixed axis gear system design. The unique combination of both power transmission efficiency and compact size allows for a lower loss in efficiency. The more efficient the gear arrangement, (i.e. spur, helical, planetary and worm) the more energy it will allow to be transmitted and converted into torque, rather than energy lost in heat. 

How to Select the Appropriate Gearbox ?

Gear ratios are defined as the correlation between the numbers of teeth of two different gears. Commonly, the number of teeth a gear has is proportional to its circumference. This means that the gear with a larger circumference will have more gear teeth; therefore the relationship between the circumferences of the two gears can also give an accurate gear ratio. For example, if one gear has 36 teeth while another gear has 12 teeth, the gear ratio would be 3:1.

How do Gearboxes Work

All gearboxes work in a similar fashion. The directions the gears rotate are dependent on the input direction and orientation of the gears. For example, if the initial gear is rotating in a clockwise direction, the gear it engages will rotate counterclockwise. This continues down the line for multiple gears. The combination of different size gears and the number of teeth on each gear plays a significant role in the output torque and speed of the shaft. High gear ratios allow for more output torque and lower speeds, while lower gear ratios allow for higher output speed and less output torque. 

Types of Geraboxes

A number of different fields use gearboxes for a wide range of applications. For this reason there are several kinds of industrial gearboxes, all with their own unique features, functions, and mechanisms. Here is a list of five common gearbox types and some important details about each.

Gearboxes

Gearboxes are used in a very wide range of industrial fields. Thanks to the use of gearboxes, a small rotation force (torque) can be used to produce a much greater rotation force, and a slow rate of revolution can be speeded up. In many industries, the gearbox, which is the equipment that transmits mechanical power, is an essential piece of equipment. This step-up unit is the:

Types of Gearmotors

Gearmotors are used in many applications in industrial applications as well as in everyday household appliances. Industrial applications include cranes, lifts, jacks and conveyor machines. Everyday household appliances gearmotors are used in are washing machines, mixers, clocks, hand tools like drills and dryers.

Planetary Gearbox

Planetary gearboxes are named so due to their resemblance to the solar system. The components of a planetary gearbox include a sun gear, ring gear and planetary gears. The sun gear is the central gear which is fixed in the center, ring gear (annulus ring) which is the outer ring with inward-facing teeth, and the planetary gears which rotate around the sun gears and mesh with both the sun and ring gear.
