An electromechanical brake comprises a friction plate which is fixed on a mechanical push unit. The mechanical push unit is connected with a motor, and comprises a shell body. A push rod is arranged in the shell body through a bearing, the portion, on the left side of the bearing, of the push rod is fixedly connected with an output shaft of the motor, and outer threads are arranged on the portion, on the right side of the bearing, of the push rod to enable the portion, on the right side of the bearing, of the push rod to become a screw rod. A slider is sleeved on the screw rod, and in threaded fit with the screw rod. The slider is connected with the shell body through a guide rail pair. A piston stretches into the shell body to be fixedly connected with the slider. The friction plate is fixed on one end portion of the piston. The electromechanical brake has the advantages that the brake is achieved through an intelligent controller and capable of automatic compensation, and has no needs for manual adjustments; and a whole control and reset process is simple and time-saving, maintenance time and labor intensity of workers are reduced, humanization is achieved, self electricity consumption of a unit is reduced, cost is lowered, and the service life of each part is long. The electromechanical brake is suitable for being used in a system with requirements for retentivity supply, and particularly suitable for being used in wind generation set.
Description
technical field [0001] The invention relates to a brake, in particular to a mechanical brake of a wind power generating set. Background technique [0002] As the competition in the wind power market becomes more and more brutal, the brake is an important part of the wind turbine. Most of them use a single mechanical braking force, which has the following defects: regular manual maintenance is required; single braking force requires high requirements for yaw drive, easy to wear transmission gears, and consumes a lot of power. Contents of the invention [0003] The object of the present invention is to provide an electromechanical brake to overcome the above disadvantages. [0004] The object of the present invention can be achieved through the following measures: [0005] An electromechanical brake, comprising a friction plate, the friction plate is fixed on a mechanical propulsion device connected to a motor, the mechanical propulsion device includes a housing, a push ro...
