The main function of the
gear box is to transmit the power generated by the wind wheel under the action of the wind power to the generator and obtain the corresponding rotation speed. Usually, the rotational speed of the wind wheel is very low, and it is far from the rotational speed required by the generator power generation. It must be achieved through the speed-increasing effect of the gear box gear pair. Therefore, the
gear box is also called a speed increase box.
[The gear box has the following functions] 1. Acceleration and deceleration is what is often called a gearbox.
2. Change the direction of the drive. For example, we can use two sector gears to transfer the force vertically to another axis of rotation.
3, change the torque. Under the same power conditions, the faster the speed of the gear, the smaller the torque on the shaft, and vice versa.
4. Clutch function: We can separate the engine from the load by separating the two originally meshed gears. Such as brake clutches.
5. Allocate power. For example, we can use an engine to drive multiple slave shafts through the gearbox spindle to realize the function of one engine driving multiple loads.
[What are the characteristics of gearbox]
1. The gearbox adopts a universal design scheme, which can be changed to a gearbox that is dedicated to the industry according to customer needs.
2. Realize parallel shafts, orthogonal shafts, vertical and horizontal universal cabinets. The types of components are reduced, and the specifications and models are increased.
3. The use of sound-absorbing speaker body structure, large box surface area and large fans, cylindrical gears and spiral bevel gears adopt advanced tooth grinding technology, so that the whole machine's temperature rise, noise reduction, operation reliability is improved, and the transmission Increased power.
4. Input method: motor connection flange, shaft input.
5. Output methods: Solid shaft with flat keys, Hollow shaft with flat keys, Hollow shaft with expansion disk coupling, Hollow shaft with splined coupling, Solid shaft with splined coupling, and Solid shaft with flange coupling.
6 gear box installation: horizontal, vertical, swing base type, torque arm type.
7. The gearbox series products have 3～26 type specifications, and the number of deceleration transmission stages is 1-4, and the speed ratio is 1.25-450; and the R, K, S series combination can get a larger speed ratio.
[gearbox lubrication method]
Common gearbox lubrication methods include gear oil lubrication, semi-fluid grease lubrication, and several methods of solid lubricant lubrication. For better sealing, high speed, large load, good sealing performance can use gear oil lubrication; for the poor sealing, low speed can use semi-fluid lubrication lubrication; for oil-free applications or high temperature applications can be used two Molybdenum sulfide ultrafine powder lubrication.
