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 may also be transmitted to the gearbox by hydraulic motors or belt pulleys, furthermore to chain gears.
Agricultural gearboxes always have one 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 generally called a right-position gearbox.
rotary tiller gearbox is adopted middle gear transmission system, mounted with the tractor of 12-80HP. Tractor wheel tracks are completely protected after tillage as the working width is much wider. The product quality is reliable and the efficiency is well. So it can be used on dry and paddy field. It can decrease the time, laboring, and cost, etc. during operation
Increasers and Reducers
When the gearboxes have the two gears with different numbers of teeth.
The gearbox is a reducer when the driving gear, i.e. the main one with the input shaft, gets the fewer amount of teeth (pinion), thus 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 output 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 teeth.
The gearbox is known as right-angle when it only has two shafts (input and output),
whereas it is called a distributor whenever there are at least two output shafts.
It is called a rotational reverse gearbox and parallel offset in the variations with parallel shafts with two gearboxes.
in addition to the primary pair of gears and relevant shafts, the gearboxes may also have various other gears with a different quantity of teeth. The gear shift of the primary pair of gears with the secondary ones enables different speeds. The manual change of the secondary gear set with gears with different number of teeth allows modifications to the gearbox for agricultural machinery result rotation speed.
