Applications of Gears

Gears are an industry essential that are used for the transmission of motion and power in clocks, instruments, machinery, vehicles, and industrial equipment. They are engineered to reduce or increase speed in motorized implements and change the direction of power smoothly and efficiently. Since their introduction thousands of years ago, gears have become an essential tool for the innovations and improvements of industry.

Made from highly durable materials, gears play a key role in the productivity of machines and the operations of manufacturing. Each type of gear has varied elements, characteristics, advantages, and properties that meet the requirements and specifications for motion or power transmission. The wide variety and number of gears makes it possible to find a gear for every application.

Setting Rotation Speed

One of the main functions of gears is to change the rotation speed of power with engines being the most common example. Gears regulate power by their ratios with different sizes of gears used to increase or decrease transmitted power by their rotation.

Transmitting Power

During the transmission of power, gears intermesh with other gears without slipping and strongly retain their connections. The motor in a machine may not be designed to move a shaft directly and uses gears to transmit power to the shaft to power a tool.

Change of Torque

Torque is the rotating force that is produced by motors and engines that is adjusted through the use of gears, gear sets, gearboxes, and gear assemblies. Smaller gears produce less torque while large gears produce higher amounts of torque. When a small gear is the drive gear to power a large gear, the amount of torque increases and speed decreases. Taken in reverse, when a large gear is the drive gear and a small gear is the powered gear, the amount of torque decreases and speed increases.

Direction of Power

A common use for gears is the changing the direction of rotation or movement, which is completed by the specific design of gear pairs. The rotational direction of a motor is dependent on the rotation of a shaft with the direction of the rotation capable of being changed by the configuration of the gears.

Gearboxes

Gearboxes are one of the most common uses of gears and are made up of an assortment of gear types contained in a housing. Gearboxes contain worm, bevel, helical, and spur gears that are engineered to change torque, speed, power, motion, and force. Gearboxes are a foundational part of motor driven vehicles and gas powered machinery.

Conclusion

• Gears are circular machines with teeth around the circumference used to produce rotary motion and torque.
• Usually gears are circular in shape but sometimes other shapes are also available such as squares.
• The speed and rotation depends on the size of the gear and the mating pair.
• The gear is determined by its tooth design, tooth profile, configuration, and size.
• Gears work on the principle of a lever.
• Axis of gears can be parallel, non parallel, intersecting, and non intersecting.
• Different types of materials are used for manufacturing gears such as metal, stainless steel, plastic, copper alloy and nickel alloy.
• All the materials have specific properties and can be selected according to its application.
• Wood and resin materials are also used for the production of gears.
• Many different types of gears are present and all have different characteristics.
• These are distinguished on the basis of its configuration and applications.
• Spur gears, helical gears, double helical gears, rack and pinion gears, internal gears, bevel gears, worm gears, and planetary gears are different types of gears.
• Some of them work on parallel axis while some work on non parallel axis.
• Plastic gears are now used commonly in many industries because of the low cost and high availability.
• Gears are used in many industries such as automotive, water pumps, toys, home appliances, trains, weighing scales, unit handling, and many more.
