What are gear used in sliding types transmission?

Different gears of Sliding Mesh Gearbox:

  • 1 First Gear : First Gear is used at the time when vechile starts its movement in forward direction.
  • 2 Second Gear: Second Gear is obtained when second largest gear of second smallest gear of lay shaft meshes with middle size gear of main shaft.
  • Third Gear:
  • Reverse Gear:

Why gears are used in machines?

Gears are used to transfer motion and torque between machine components in mechanical devices. Depending on the design and construction of the gear pair employed, gears can change the direction of movement and/or increase the output speed or torque.

What is mesh gear?

Constant mesh gearbox is a type of Transmission in which all or most of the gears are always in mesh with one another, as opposed to a sliding-gear transmission, in which engagement is obtained by sliding some of the gears along a shaft into mesh.

Which type of gear are used in sliding mesh gearbox?

Sliding mesh gearboxes are made with the spur gear. The gears in the layshaft are rigidly fixed shaft. The gears in the main shaft alone can move along the spline. The selector fork moves the gear and moves the perfect mesh with the required gear in layshaft when the gear lever is shifted.

What are gears used?

Gears are mechanisms that mesh together via teeth and are used to transmit rotary motion from one shaft to another. Gears are defined by two important items: radius and number of teeth. They are typically mounted, or connected to other parts, via a shaft or base.

What is gear types of gear?

Types of Gears

  • Spur Gear. Gears having cylindrical pitch surfaces are called cylindrical gears.
  • Helical Gear. Helical gears are used with parallel shafts similar to spur gears and are cylindrical gears with winding tooth lines.
  • Gear Rack.
  • Bevel Gear.
  • Spiral Bevel Gear.
  • Screw Gear.
  • Miter Gear.
  • Worm Gear.

What is sliding mesh gear?

An obsolete type of transmission or gearbox in which the gears on the layshaft are fixed to the shaft rigidly, whereas the gears on the main shaft can slide on it by means of splines but are otherwise in permanent rotational mesh with the shaft. The figure below shows the arrangement of sliding mesh gear box.
