What is difference between gear and gearbox?

The gears are mounted on shafts, which are supported by and rotate via rolling element bearings. The gearbox is a mechanical method of transferring energy from one device to another and is used to increase torque while reducing speed.

What is a gear train?

A gear train is a mechanical system formed by mounting gears on a frame so the teeth of the gears engage. Gear teeth are designed to ensure the pitch circles of engaging gears roll on each other without slipping, providing a smooth transmission of rotation from one gear to the next.

What are gears and gear trains?

Gears and Gear Trains- Gears is a positive drive which transmits exact velocity ratio from one shaft to another shaft, gear drive is used when the distance between driver and follower is very less, when two or more gears are made to mesh with each other to transmit power from one shaft to another, the combination is …

Is transmission box same as gearbox?

“Transmission” is the American term for what the English call a gearbox. When the English say “transmission” they are talking about the car’s entire drive train, not just the gear box. They also call gasoline “petrol” and sidewalks “pavement”.

What are the 3 gears in a gear train?

In a compound gear, each intermediate shaft has two gears, rotating at the same speed. Fig. 3.2. A gear train using compound gears; gear 1 is on the input shaft, gears 2 and 3 are compound gears on shaft A; gears 4 and 5 are compound gears on shaft B and the gear 6 is mounted on the output shaft.

What is the function of gearbox?

The gearbox is a mechanical device used to increase the output torque or to change the speed (RPM) of a motor. The shaft of the motor is connected to one end of the gearbox and through the internal configuration of gears of a gearbox, provides a given output torque and speed determined by the gear ratio.

How does a train gearbox work?

The traction motors provide propulsion power to the wheels. There is one on each axle. Each motor drives a small gear, which meshes with a larger gear on the axle shaft. This provides the gear reduction that allows the motor to drive the train at speeds of up to 110 mph.

Where is a gear train used?

Gear trains are used in almost all machines which are dealing with the mechanical power. Some of the places where gear trains are used are engines, lathes, clocks, gear box and Differential of automobiles etc.

What are the different types of gear train?

We have generally 4-types of gear trains, and those are:

  • Simple Gear Train.
  • Compound Gear Trains.
  • Reverted gear Trains.
  • Epicyclic Gear Trains.
