Definitions
- the object of the invention is to provide a wind turbine, with a power range close to 1 MW, of a mechanical brake that keeps the rotation axis locked during the start-up and maintenance operations of the wind turbine and that In turn, it meets the requirements of the emergency brake during braking due to a failure in the pitch mechanism.
- the mechanical transmission system or power train of a wind turbine consists of a wind rotor, a multiplier (since the turbine's rotation speed does not normally correspond to that of the generator) and an electric generator.
- the power train includes a low speed shaft that is coupled between the wind rotor and the multiplier and a high speed shaft that is coupled between the multiplier and the generator.
- the mechanical brake is included in the power train, whose function is to block the turbine in maintenance operations and eventually contribute to emergency stops such as the one that may occur in the face of the pitch mechanism failure preventing the flagging of the blades.
- the stop of a wind turbine is one of the most critical operations because it involves the generation of large loads that directly affect the wind turbine components.
- the physical constitution of the mechanical brake consists of a disc that rotates in solidarity with the drive shaft and brake calipers that rub against the disc when activated either by electric, hydraulic or pneumatic means.
- the critical braking of maximum energy lasts a certain time, since the torque must be of a certain determined value to stop the machine. This energy is converted to heat in the disk and its temperature rises. To maintain acceptable temperatures (above which the system overheats and fails), the volume of the disk must be of a certain value so that its thickness and diameter can be increased. Having a thick disk does not help much because heat is generated on the surface of it. During the braking time there is not enough time for a lot of heat to be driven from the surface to the middle plane of the disc. Therefore there is a gradient of disk temperature that decreases inward or midplane. There is therefore a practical limit of disc thickness beyond which there is no benefit of significant reduction in surface temperature when the thickness increases.
- the brake diameter of a wind turbine near the power of 1 MW is such that it would interfere with the adjacent elements in that position of the nacelle (mainly yaw motor-reducers) and its wear and maintenance would make it An excessively expensive item.
- the mechanical brake When the mechanical brake is designed solely to block the rotor, the torque generated in the power train that it must withstand is that transmitted by the the wind rotor set in flag in extreme wind conditions. However, in addition to the blocking function, the mechanical brake can be used for dynamic braking of the wind rotor during emergency stop processes (with the blades in power position).
- Figure 1 shows a general representation of certain elements of a wind turbine, including a double disc integral to the transmission shaft.
- Figure 2 represents a perspective view of the double disk and a section thereof.
- Figure 3 is a perspective view of the assembly mounted on the multiplier. Description of the preferred embodiment
- the mechanical brake object of the invention is formed by two discs (D1 and D2) parallel and separated a sufficient distance to allow the actuation of calipers (P1 and P2) provided with brake pads, located diametrically opposite and each of them applies its braking force on its corresponding disc.
- Figure 2 shows the two disks (D1 and D2) and a section thereof.
- the central part of the discs there are oval grooves (Ro) that pass through the set of the two discs allowing the insertion of straps, anchors or hooks for handling and placement on the high axis (Ea).
- the central circle (Ce) has a key (Ch) that interlocks all the discs with the axis movement.
- the disc brake necessary to carry out this certification being a double disc, can have a smaller diameter which allows it to adapt to the space between the multiplier (M) and the generator.
- M multiplier
- the diameter of a single disc of the same thickness that is heated in the same way that the double disc in said braking would have a diameter in excess of 800 mm and would interfere with other mechanical elements within the nacelle, which also makes it unfeasible. Additionally, this single disc would require deeper pliers to accommodate wider, longer and structurally reinforced pads with thicker sections of material to withstand the higher loads due to larger bending moments at the junctions of the two halves, which would be very large weight and higher cost, thus hindering installation and maintenance work.
