Gear Manufacturers: application of gearboxes

First, gearbox manufacturers: the role of the gearbox

1. Acceleration and deceleration, usually called variator.

2.Change the transmission direction. For example, we can use two sector gears to transfer force perpendicular to another axis of rotation.

3. Changing the torque. At the same power, speed: the faster the transmission, the less torque on the shaft and vice versa.

4.Clutch function: We can separate the engine from the load by separating the two initially engaged gears. For example, the brake clutch, etc.

5. Power distribution. For example, we can use a single motor to drive several driven shafts through the main shaft of the gearbox, thus realizing the function of a single motor driving several loads.

Secondly, gearbox manufacturers: treatment of gearbox noise

The gearbox in the process of operation, due to the tooth pitch, tooth profile, etc., will inevitably produce errors, therefore, in the process of operation, there will be an impact engagement, and will produce corresponding noises with the gear engagement frequency, and due to the relative slip between the teeth, it will also produce surface friction noise. Gearbox manufacturers claim that since gears are the main components of a transmission transmission, reducing gear noise is necessary to control gearbox noise. In general, the main causes of gearbox noise are the following:

1. Transmission design. Incorrect choice of parameters, too little overlap, incorrect modification of the tooth profile or lack of modification, unreasonable gearbox structure, etc. When processing gears, the basic error of the pitch and tooth profile is too large, the lateral gap of the tooth is too large, the surface roughness is too large.

2.The eccentricity of the gearbox components, low contact accuracy, poor shaft parallelism, insufficient bearing stiffness, low rotation accuracy, incorrect clearance.

3.Different input torque. Load torque fluctuations, torsional vibrations of the shaft system, the balance of the engine and other transmissions.

The relevant information about the gearbox manufacturer is given above, I hope it will help the company.
