gearbox for agricultural machinery

Agricultural Gearbox
The agricultural gearbox is the main mechanical component 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 operating torque may 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 one particular output shaft. If these shafts are positioned at 90° to one another, the gearbox can be an ORTHOGONAL ANGLE gearbox or more typically called a right-angle gearbox.

rotary tiller gearbox is adopted middle gear transmission program, mounted with the tractor of 12-80HP. Tractor wheel tracks are completely covered after tillage as the operating width is much wider. The quality is reliable and the performance is well. So it can be used on dry and paddy field. It can decrease the time, laboring, and price, etc. during operation

Increasers and Reducers
When the gearboxes have both gears with different numbers of teeth.
The gearbox is a reducer when the driving gear, i.e. the one with the insight shaft, has the fewer amount of teeth (pinion), therefore the result shaft rotates slower than the input shaft.
It is called an increaser when the insight shaft is mounted on the apparatus with the larger quantity of teeth (crown), thus 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 teeth.
The gearbox is called 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 really is called a rotational reverse gearbox and parallel offset in the versions with parallel shafts with two gearboxes.

Speed change
in addition to the main pair of gears and relevant shafts, the gearboxes may also have other gears with a different quantity of teeth. The gear shift of the main couple of gears with the secondary types allows different speeds. The manual switch of the secondary gear set with gears with different number of teeth allows adjustments to the result rotation speed.
