Specification

HCQ501 marine gearbox possesses functions of speed reduction, ahead and astern, clutching and de-clutching, and bearing propeller thrust. Featuring in compact in structure, small in volume and light in weight, it can match high-speed engine to form ship power unit.

HCQ501 marine gearbox is suitable for medium high-speed boats such as yacht, traffic, passenger and cargo boats.

Gearbox

Gearboxes have a wide range of applications, such as in wind turbines. Gearboxes are an important mechanical component that is widely used in wind turbines. Its main function is to transfer the power generated by the wind wheel under the action of wind to the generator and make it get the corresponding speed.

Generally, the rotation speed of the wind wheel is very low, far less than the rotation speed required by the generator to generate electricity. It must be realized by the speed increasing effect of the gear pair of the gear box, so the gear box is also called the speed increasing box.

Noise treatment of Gearbox

Gearbox is an important component widely used in mechanical transmission. When a pair of gears mesh, due to the inevitable error of tooth pitch and tooth profile, meshing shock will occur during operation and noise corresponding to the gear meshing frequency will occur. , Friction noise also occurs due to relative sliding between the tooth surfaces. Since gears are the basic parts of gearbox transmission, reducing gear noise is necessary to control gearbox noise. Generally speaking, the main reasons for gear system noise are as follows:

1. Gear design. Improper parameter selection, too small overlap, improper or no modification of tooth profile, unreasonable gear box structure, etc. In terms of gear processing, the base pitch error and tooth profile error are too large, the tooth side clearance is too large, and the surface roughness is too large.

2. Gear train and gear box. The assembly is eccentric, the contact accuracy is low, the parallelism of the shaft is poor, the rigidity of the shaft, bearing, support is insufficient, the rotation accuracy of the bearing is not high, and the clearance is improper.

3. Other input torque. The fluctuation of load torque, the torsional vibration of the shaft system, the balance of the motor and other transmission pairs, etc.

Lubricating of Gearbox

Commonly used gearbox lubrication methods include gear oil lubrication, semi-fluid grease lubrication, and solid lubricant lubrication. For better sealing, high speed, high load, and good sealing performance, you can use gear oil lubrication; for poor sealing performance and low speed, you can use semi-fluid grease for lubrication; for oil-free occasions or high temperature occasions, you can use two Molybdenum sulfide ultrafine powder lubrication.
