Reverse Your PTO Output With a Reverse PTO Gearbox

You can reverse your PTO output by changing the gears in the implement gearbox. However, it is important to note that not all implement gearboxes reverse their output. Choosing the right tractor PTO reverser gearbox for your implement requires careful study. For example, you must know what to look for in the gearbox. The outputs of the gearbox are reversed when the top and bottom are flipped over. The mounting holes are located on the top and bottom, so you must take care to flip the gears in the right direction. The precision special gears manufacturer offers spur gears, helical gears, worm gears, and miniature gears. These gears can be made of steel or other materials. The process to make these parts include turning, boring, and heat treating.

Single gear PTO

A single gear reversing planetary gearbox works on the principle of axial displacement. When the driver shifts into reverse, the axial displacement of the gears is larger than that of the low gear. The ratio of helix angles in the gears must be less than 10 degrees. The speed reduction ratio is used to determine the shaft diameters of the power transmission unit parts. Typically, a single gear reversing planetary gearbox is a simple, cost-effective solution.

The axial offset can be compensated by bevel helical or hypoid gear pairs. As the axial offset increases, the efficiency of a reversing gear decreases. A helical screw drive is necessary to achieve large axial offsets. In order to achieve a direct connection between the input and output shafts, a cardan shaft combination is required. A bevel gear has poor efficiency but can achieve a high ratio if the gears are translated.

Parallel shaft PTO

A parallel shaft reversing gearbox is one type of transmission system that reverses a vehicle's direction while driving. Its basic function is to transfer the driving force from the engine to the output shaft at a reduction ratio appropriate for the selected gear train. There are three types of gear trains: the first change gear train, the second-change gear train, and the third-change. The gear trains are connected by clutch means located on the input and second-counter shafts.

The ratio between the drive gear and the driven gear is known as the gear ratio. This ratio can be expressed in any direction, although it is generally defined as the smaller gear divided by the larger one. Other references define the ratio as the smaller gear divided by the larger one, irrespective of the direction of power transmission. Some other expressions show the relationship between the pitch diameter and the number of gear teeth. Hence, a parallel shaft reversing gearbox may be referred to as a "concentric gearbox."

Tractor PTO

A PTO reversing gearbox for a tractor can allow the user to backward power the transmission. The PTO shaft of a tractor is used to power implements. Most PTOs are located in the rear. When the clutch is depressed, the attached implement will back-power the transmission. If the attachment mechanism is heavy, the PTO may be difficult to reverse without a dedicated overrunning clutch.

There are two main types of independent PTOs: hydraulic and mechanical. Hydrostatic PTOs are the most popular. These reversing gearboxes are the most reliable and easy to use. These units also save on energy. Independent PTOs are great for farming, haying, and other heavy-duty applications. They are easy to engage, and you can activate them while the tractor is in motion.

PTO Shaft for Agricultural Gearboxes

The agricultural equipment includes a variety of PTO shafts. Each is connected by a yoke at each end and rotates between 540 and 1,000 rpm. Safety guards (PTO shaft safety covers) are usually mounted on both ends of the PTO shaft to protect the operator. These guards are also found on tractors and farm equipment, and they ensure maximum efficiency. The use of internal yokes also provides additional safety.
These agricultural PTO gearboxes are designed to vary the output speed of the PTO drive shaft. It can be used as a gearbox to reduce or increase the transmission ratio. With a reduction ratio gearbox, it reduces the speed of the PTO shaft from 1000 rpm to 540 rpm, allowing you to use equipment designed for 540 rpm. On the other hand, a gearbox with increased ratio increases the speed of the PTO drive shaft from 540 rpm to 1000 rpm.
