Gear Box cmr replacement

Gearbox is widely used, for example, in wind turbine. Gearbox is an important mechanical component widely used in wind turbine. The main function of the wind turbine is to transfer the power generated by the wind turbine to the generator and get the corresponding speed.

What is a gearbox

Usually, the speed of the wind wheel is very low, which is far from the speed required by the generator. It must be realized through the speed increasing effect of the gear pair of the gearbox, so the gearbox is also called the speed increasing box.

1. Accelerate and decelerate

2. Change transmission direction

3. Changing the rotational torque

4. Clutch function

5. Distribute power

Acceleration and deceleration

Acceleration and deceleration, which is commonly known as the gearbox.

Change direction

Change the transmission direction. For example, we can use two sector gears to transfer the force vertically to another shaft.

Change the rotation torque

Change the rotation torque. Under the same power condition, the faster the speed of the gear, the smaller the torque on the shaft, and vice versa.

Nature Hike

Clutch function: we can separate the engine from the load by separating the two gears that were originally meshed, such as the brake clutch.

Noise Treatment

Gear Design

Gear design. Improper parameter selection, too small overlap, improper or no profile modification, unreasonable gearbox structure, etc. In gear processing, the pitch error and tooth profile error are too large, the backlash is too large, and the surface roughness is too large.

Gear Train and Gearbox

 Gear train and gearbox. Assembly eccentricity, low contact accuracy, poor parallelism of shaft, insufficient stiffness of shaft, bearing and support, low rotation accuracy and improper clearance of bearing, etc.

 Input torque from other aspects.

Input torque from other aspects. Fluctuation of load torque, torsional vibration of shafting, balance of motor and other transmission pairs, etc.


Gearbox torque

In order to change the speed (RPM) or the output torque of a motor, a mechanical device needs to be used – a gearbox. The shaft of the motor is attached to one side of the gearbox and offers a given torque as output and speed which is determined by the gear ratio, through the internal arrangement of gears within a gearbox.

Operation Mode

All types of gearboxes operate in a similar manner. The direction that the gears rotate is contingent on the orientation and input direction of the gears. An example would be if the initial gear is revolving clockwise, the gear that it engages will be revolving in the opposite direction – counterclockwise. With multiple gears, this continues all throughout the line. The combination of various size gears and the quantity of teeth that each gear has plays a major role in the speed of the shaft as well as the output torque. When the gear ratios are high, it allows for lower speeds and more output torque, whereas less output torque and higher output speeds can be achieved with lower gear ratios.
