What Do You Mean by ‘Special Gears’?

There are certain applications where the standard gears cease to work properly. In such cases, special gears are used. They are different from standard gears in the number of teeth, size and the material they are made from. They are used for special applications. 

All the top gears specials come with a special shape and size to fulfil the requirement of a specific job. 

Fun Fact 1: “Gearless... Gears? Magnetic gears don't touch at all, using magnetic fields instead of physical teeth to transmit power. Because they don't touch, they don't wear out, are extremely quiet, and can operate inside sealed containers without needing a shaft seal.”

State the Types of Special Gears

The following are the types of special gears:

Sector Gears

These are no circles. They are pie-shaped pieces employed when the movement needed is an arc as opposed to a full 360° rotation (e.g., steering mechanisms).

Non-Circular Gears

These gears are of elliptical or irregular shape. They are designed to give variable speed ratios in one turn, commonly seen in textile equipment or in packaging.

Hypoid Gears

Just like the Spiral Bevel Gears, except the axes are not in contact (the axes do not meet). This permits a bigger pinion and much smoother, quieter operation, as found in auto rear axles.

Herringbone Gears

A herringbone gear is some sort of double helical gear consisting of two opposite helixes. This design eliminates axial thrust (lateral force) generated by typical helical gears and is thus used in heavy-duty machinery.

Harmonic Gears (Strain Wave Gearing)

In these the flexible gear is used to obtain very high reduction ratios in a very small enclosure with very low backlash.

Internal Gears

Gears in which the teeth are cut on the inside of a cylinder. They are necessary to planetary gear systems in automatic transmission.

Many industries use special gearbox to have unique torque, space and space constraints in Indian machinery. All these factors are taken care of by Swadeshi Gear, making them a preferred choice for a wide number of industries.

Understand the Advantages of Special Gears.

Here are the advantages of special gears:

  • Work in extreme working conditions.
  • Superior load Distribution
  • Reduce Noise
  • Vibration
  • Enhance durability
  • High-efficiency performance

Special gear suppliers make sure that all the clients get products with excellent work performance. 

Fun Fact 2: “"Sacrificial" Gears: In many modern machines, gears are made of nylon or other plastics. These act as "sacrificial" parts, designed to break first if the machine jams, preventing costly damage to the motor. “

What Makes Special Gears Different From Other Gears?

The following are the points of special gears that make them different from other gears:

  • Design Structure 
  • Material Composition
  • Application-specific engineer
  • Premium Pricing
  • Variable Motion
  • Load Sharing Capacity
