The agricultural gearbox is the main mechanical component of the kinematic chain of agricultural machines. It is normally powered by the tractor power take-off via the PTO shaft and the gearbox drives. The working torque can also be transmitted to the gearbox by hydraulic motors or belt pulleys, in addition to chain gears.
Agricultural gearboxes always have a single input shaft and at least 1 output shaft. If these shafts are positioned at 90° to one another, the gearbox can be an ORTHOGONAL ANGLE gearbox or more commonly called a right-angle gearbox.
rotary tiller gearbox is usually adopted middle equipment transmission system, mounted with the tractor of 12-80HP. Tractor wheel tracks are totally covered after tillage as the operating width is much wider. The quality is dependable and the functionality is well. So that it can be used on dry and paddy field. It can reduce the time, laboring, and cost, etc. during operation
Increasers and Reducers
When the gearboxes have both gears with different amounts of teeth.
The gearbox is a reducer when the driving gear, i.e. the main one with the input shaft, gets the fewer number of teeth (pinion), hence the output shaft rotates slower than the input shaft.
It is called an increaser when the input shaft is mounted on the gear with the larger quantity of teeth (crown), hence the output shaft rotates faster than the input shaft.
Right-angle gearboxes, distributors or rotational reverse gearboxes
When the gearboxes have gears with the same number of tooth.
The gearbox is known as right-angle when it only has two shafts (input and output),
whereas it really is called a distributor when there are at least two output shafts.
It really is called a rotational reverse gearbox and parallel offset in the versions with parallel shafts with two gearboxes.
in addition to the primary couple of gears and relevant shafts, the gearboxes may also have additional gears with a different amount of teeth. The gear shift of the primary pair of gears with the gearbox for agricultural machinery secondary types allows different speeds. The manual change of the secondary gear pair with gears with different number of teeth allows adjustments to the output rotation speed.
