Gearboxes

The gearbox is the principal mechanical component of the kinematic chain of agricultural machines. It is normally pushed by the tractor electrical power get-off through the PTO shaft and the gearbox drives. The running torque can also be transmitted to the gearbox by hydraulic motors or belt pulleys, in addition to chain gears.

Gearboxes constantly have 1 enter shaft and at the very least a single output shaft. If these shafts are positioned at 90° to every single other, the gearbox is an ORTHOGONAL ANGLE gearbox or a lot more typically called a appropriate-angle gearbox.

Agricultural gearbox te chnical requirements

 

 

1. There must be no mechanical damage or casting defects such as cracks and holes in any part of the agricultural gearbox.

2. The surface of the gearbox of the machine tool should be kept clean, and the surface finish of the shaft should not be lower than 76.

3. The ellipticity of each shaft hole of the agricultural machinery gearbox is not greater than 0.015-0.02mm.

4. The irregularity of the center line of each shaft hole is not more than 0.04mm, and the length is 100mm.

5. Wheelbase of agricultural machinery gearbox.

6. The relationship between the bearing hole and the bearing seat of the agricultural gearbox.

How to Maintain a PTO Gearbox?

If your PTO gearbox does not work properly, you will have to replace this agricultural gearbox. There are many reasons why you might want to change it. Here are some of the reasons. You will also need to check the compatibility. It will be difficult to find a PTO gearbox for a larger model. But if you are not sure, you should visit a dealer or technical support center to learn more.

Ensure that the working temperature of your PTO gearbox is below 102 degrees Celsius. Ensure that the torque figures in the technological chart of your PTO gearbox are constant – you will be operating the gearbox under intermittent conditions, so they can be over 20% higher than they are in normal operating conditions. You should also remember that you should always change the gear oil in your PTO gearbox if you are not using it for a long time.

You can buy PTO gearbox 90 degrees to use for agricultural machinery. These are useful for connecting gear pumps to your farm tractor. They are made of substantial mechanical resistance iron or shell-sound aluminum. They are made according to the ISO/DIN 3990-88 expectations. Besides, Stub teeth ensure that the resistance is high, and they run quietly. Theses PTO gearboxes are also made for higher power handling rates.
For 60 years we have been manufacturing PTO shafts, safety devices, torque limiters, gearboxes, speed multipliers and speed
reducers for agricultural mechanization.
