Gearboxes are basically used to one form of energy into another, hence they are used in different machines. Since gearboxes are essential to control, lift and move tools, it is vital to be familiar with the problems that may arise in them and how to solve them.
Here are a few common problems that a worn out or old gearbox may sustain:
Gearbox gets heated
Gearboxes can get heated for a number of different reasons and may require maintenance to set that right. Here’s why they might be overheating:
● Improper ventilation: Machines need to stay cool and need proper ventilation for them to work properly. Any machine that works at a stretch gets heated, and this overheating can cause problems. When gearboxes get extra heated, they malfunction and convert less energy into torque.
● The shaft is not aligned properly: If the input shaft is not attached to the gearbox in the right way, it will lose excess heat and make the gearbox hot. Make sure to align the shaft to the gearbox correctly to avoid this problem.
● Poor lubrication: When poor lubrication or no lubrication is used, it can block the shafts and get them heated. Make sure to check the level of lubrication timely.
● Overload: The temperature in the gearbox will rise if the appliance is carrying or moving more load than it is supposed to. Either decrease the load or choose a gearbox that can carry more load if you must.
Making Loud Noise
● Not installed correctly: When the components of the gearbox aren’t installed correctly or if they become loose with time then the gearbox will start to produce loud grunting noise while changing gears. Tighten the bolts that you feel are loose and also make sure that motor is aligned with the gearbox.
● Input speed is too high: If you’re trying to operate the appliance at max then it may cause a loud noise. Keep the speed at least below maximum to avoid the noise.
● Damaged or worn out bearings: When bearings get damaged due to constant use or poor lubrication, the gearbox might make a noise. Replace the damaged bearings to solve this problem.
Shafts Do Not Rotate Completely
When gear teeth are worn, damaged or there’s some kind of blockage in the gear teeth then the shafts may not rotate at the desired speed or may not move at all. Make sure to keep the gear teeth cleaned and smooth to avoid this problem.
Another reason can be improper installation of the shaft. Make sure you’ve fasted the motor and the gearbox with bolts.
Gearboxes can become less efficient for many reasons. They may have become old and worn out. Their efficiency is diminished due to excessive load. Another reason is the ambient temperature of the gearbox system being more than the advised temperature (in this case a cooling fan may work and reduce temperature).
If you’re facing any of the above-mentioned problems, you need to get your gearbox to work properly again. You can also check this website for more tips.
