Gear box:
After 2019, the method of transmitting power to our wind turbines changed. Instead of a chain drive, between the turbine and the generators, which we used before, now the power transmission is done with a gear box.
The new gear box model is manufactured entirely by the company IASOS S.A.
The gearbox increases the rotational speed of the turbine shaft by 12.34 times. This means that when the turbine performs one rotation per minute, the generator performs 12.34 revolutions per minute. Given that the generator delivers maximum power at 300 RPM this means that to achieve this maximum power (2.5 KW) the turbine will have to rotate 24.3 RPM.
The increase in speed is achieved initially with the use of angular hypoid gear in a ratio of 6/37 and then, in the second stage, with frontal helical gears the ratio is doubled.
All distances between the gears can be adjusted so that after too many hours of operation, the gearbox can be adjusted again. This ensures that the gearbox can be operated for many years.
The gear box is equipped with a lubricating oil pump, with two cogwheels, which is driven by a gear in engagement with the output gear.
The connection of the gear box on the one hand with the turbine and on the other hand with the first generator is done with a flexible rubber connection, in order to exclude any transmission of noise or vibrations.
The connection of the gear box on the one hand with the turbine and on the other hand with the second generator is done first with a electromagnet clutsh and after with flexible rubber connection, in order to exclude any transmission of noise or vibrations.
The power loss during operation of the gear box, at an output speed of 300 RPM, is 0.95 Nm.
The gear box has an oil temperature indicator and an oil level indicator.
The gear box housing as well as the special oil filling stage are designed to function as a cooling device.
