Gear box

Gear Boxes for Industrial and Agricultural Purposes

You may use a gear box to increase the output torque or change the speed (RPM) of a motor. The motor’s shaft is attached to one end of a gear box and it receives the output through the internal configuration of gears. Gear boxes are excellent tools, aiding the manufacturing machines in industries or agricultural equipment. These settings demand appliances with high load handling capacity, energy efficiency and the ability to withstand extreme temperatures.

Quality gears provide the required force and the output depends upon the type of configuration within the box. You can be assured of top-notch products at Southern Rewind Ltd. to suit your requirements.

You can find gear boxes in industrial, agricultural or everyday appliances like –

 

·         Washing machines

·         Mixers

·         Clocks

·         Drills and dryers

·         Cranes

·         Lifts

·         Jacks

·         Conveyor machines

·         Tractor and pumps

·         Pest and insect control

 

Physical Properties and Types

 

The gear boxes from different manufacturers vary from each other in make and build. They can be made of steel, aluminum, iron or brass. Some like spur gear boxes are made with polycarbonate or nylon.

Gear teeth play a major role in determining the overall efficiency; straight teeth are noisy and used in low-speed applications, whereas helical ones are quieter and used in high-speed applications.

There are several types of gear boxes depending upon the sizes, ratios and efficiencies. Some of the common ones are:

 

Bevel Gear Boxes – These are durable and used for right-angle configuration. Since they are made from iron or aluminum, they can be noisy. They have either straight or spiral teeth gears. The industries in which they are generally used are:

  • Printing press
  • Differential drives
  • Hand drills
  • Automobiles
  • Power plants

 

Helical Gear Boxes – Helical gear teeth are so designed to allow gradual contact between them. It allows smoother and quieter operations in high horsepower applications. They are constructed from cast iron or aluminum alloy material. Its application is present in:

  • Blowers
  • Food and labeling
  • Cutters
  • Elevators
  • Oil industry

 

Spur Gear Boxes – Spur gears have straight teeth mounted on a parallel shaft. The colliding teeth are relatively noisy and prone to wear. These can be made from plastic materials, steel or brass. They are used to reduce the speed of applications with high torque. Compact and cost-effective, they are found in packaging units, power plants and construction sites.

 

Worm Gear Boxes – Worm gears are less noisy, can withstand high shock loads and are almost maintenance-free. It consists of a steel worm structure which turns the gear but the gear cannot turn it; it is held in a lock position when not active. Made of steel, they offer high-precision work and can be used in braking systems. They are mostly used in:

  • Presses
  • Elevators or escalators
  • Rolling mills
  • Mining

 

Planetary Gear Boxes – As the name suggests, the arrangement of planetary gear boxes resemble a solar system. The major components are:

  • A sun gear fixed in the centre
  • Ring gear on the outer edge with teeth facing inwards
  • Planetary gears rotating around the sun gears, meshing with both the sun and the ring.

 

Such gears are compact, offer efficient power distribution and high power density. They are used in applications with high torque to weight ratios like-

  •  Automobiles
  • Cranes
  • Lifts
  • Slewing drives

 

How Do Gear Boxes Work?

 

Gears work in combination with gear motors. The motor can be AC, DC, brushless or a stepper. In agricultural settings, the machinery includes double-row roller bearings and double-row angular contact ball bearings. They are designed to minimize frictional losses and provide effective support in mud, heat, dust and moisture. Special sealing elements, adequate lubricants and bearings are crucial to ensure the proper operation of the gear boxes in agricultural or industrial machines.
