The agricultural gearbox is the primary mechanical element of the kinematic chain of agricultural machines. It is normally driven 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 will have a single input shaft and at least one output shaft. If these shafts are positioned at 90° to each other, the gearbox can be an ORTHOGONAL ANGLE gearbox or more typically called a right-position gearbox.
rotary tiller gearbox is usually adopted middle gear transmission system, mounted with the tractor of 12-80HP. Tractor wheel tracks are completely covered after tillage as the working width is much wider. The quality is gearbox for agricultural machinery dependable and the performance is well. So that it can be used on dry and paddy field. It can reduce the time, laboring, and price, 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.electronic. the main one with the input shaft, gets the fewer quantity of teeth (pinion), hence the output shaft rotates slower compared to the input shaft.
It is called an increaser when the insight shaft is mounted on the gear with the larger quantity of teeth (crown), hence the result shaft rotates faster compared to 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 is called a distributor when there are at least two output shafts.
It is called a rotational reverse gearbox and parallel offset in the versions with parallel shafts with two gearboxes.
in addition to the main pair of gears and relevant shafts, the gearboxes could also have additional gears with a different number of teeth. The apparatus shift of the main couple of gears with the secondary types enables different speeds. The manual change of the secondary equipment pair with gears with different quantity of teeth allows adjustments to the result rotation speed.
