MECHANICAL BRAKE FOR A WIND TURBINE

摘要

The mechanical brake comprises a double disc (D1 and D2) rotating with the transmission shaft and some brake calipers (P1 and P2) that apply friction on the disc when activated electrically, hydraulically or pneumatically. The brake is characterized because its high-speed shaft (Ea) is equipped with a drive train, adapting its diameter to some dimensions marked by the existing space and anchoring the brake calipers directly to the cover of the gearbox (M). The mechanical brake thus constituted is capable of braking with the pitch actuator in power position, in initial conditions of nominal power and at nominal average wind speed for an installation below 1 MW.
