GEARBOX

What is Gearbox ?

The gearbox is a kind of speed change device that realizes the speed change effect through the meshing of large and small gears and has many applications in the speed change of industrial machinery. The large gear is installed on the low-speed shaft in the gearbox, and a small gear is installed on the high-speed shaft. Through the meshing and transmission between the gears, the process of acceleration or deceleration can be completed.

Principles of Gear Box:

A gearbox consists of gears of varying sizes, because of the different demands in times of the torque needed at the wheels depending upon the road, load, and terrain, for example; climbing vehicles require higher torque than driving on a straight road.

The gears vary size from first to the last in decreasing ratio, thus it empowers varying combinations in pulling ability and speed.

Steps involved in the working of Gearbox:

• The constant-mesh gearbox includes a drive shaft connected to a gear which is messed with a gear mounted on a layshaft.
• The layshaft includes various gears, arranged with the gears of the mesh.
• The gears are not directly linked to the main shaft and can be rotated freely around it.
• Dog clutches are used to engage the gear and also are splined to the primary shaft, which helps in the rotating process.
• The Dog clutches are also assigned with the frictional material which helps them to connect with the gear on the main shaft.
• When the driver pushes the gear stick, the selector fork moves the interconnected dog clutch to engage with a gear.
• As a result, the clutch and the main shaft rotate with the speed of the gear selected.

What are the types of Gearbox ?
