The agricultural gearbox is the main mechanical element 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 will have one input shaft and at least one output shaft. If these shafts are positioned at 90° to one another, the gearbox is an ORTHOGONAL ANGLE gearbox or more commonly called a right-angle gearbox.
rotary tiller gearbox can be adopted middle equipment transmission program, 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 reliable and the performance is well. So it can be utilized 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 numbers 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), thus the output shaft rotates slower than the input shaft.
It is named an increaser when the input shaft is mounted on the gear with the larger quantity of teeth (crown), therefore the output shaft rotates faster than the input shaft.
Right-angle gearboxes, distributors or gearbox for agricultural machinery rotational invert gearboxes
When the gearboxes have gears with the same number of the 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 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 various other gears with a different number of teeth. The gear shift of the main pair of gears with the secondary types allows different speeds. The manual switch of the secondary equipment pair with gears with different amount of teeth allows modifications to the output rotation speed.
CMR GROUP will be able to design and manufacture also agricultural machinery applications.
