A High Reliability Electromagnetic Power Loss Brake
Release time:
2021-09-29
High-speed rotary servo mechanism is widely used in industrial manufacturing, deep space exploration and other fields. With the development of industrial science and technology, this kind of rotary servo mechanism is required to have the function of locking and braking in some occasions, such as the electric push rod with screw nut pair to realize the conversion of movement mode. The existing brake has low reliability in a wide ambient temperature range due to the defects of the braking method used. In view of the working situation under wide ambient temperature, an electromagnetic power-loss brake is designed, which can exist in the form of components, work reliably in a wide range of ambient temperature, and support high-speed follow-up, which has a wide range of application value and scientific and technological innovation significance.

Technical Points: In order to solve the problems existing in the prior art, technicians provide a highly reliable electromagnetic power-off brake. When the brake solenoid valve is not energized, the spring pushes the moving disc to the friction disc to jam and lock the output shaft, thereby realizing the braking function; after the solenoid lead wire is energized, under the action of electromagnetic force, the moving disc Overcome the pressure of the spring and adsorb on the housing, the friction disc is released, and the output shaft can rotate with the rotating servo mechanism. According to the technical solution of the electromagnetic power failure brake, a high-reliability electromagnetic power failure brake is characterized in that it includes an electromagnet assembly, a moving disc end cover brake assembly and an output shaft; the electromagnet assembly includes a housing and a solenoid; The shell is provided with an annular cavity, and the solenoid is arranged in the annular cavity of the shell; the shell is provided with a central axial through hole matched with the output shaft, and the outer end of the axial through hole is equipped with a bearing supporting the output shaft; the brake assembly of the moving disc end cover includes a moving disc, a friction disc, a front end cover and a compression spring; the front end cover is fixedly arranged at the open end of the housing, the front end cover is provided with a central through hole, and the central through hole is provided with a support output shaft Bearing; the friction disc is arranged on the output shaft and can rotate synchronously with the output shaft; the moving disc is arranged in the housing between the solenoid and the friction disc; A limit post parallel to the axial direction of the output shaft is arranged at the fit of the moving disc and the housing; the limit post limits the axial rotation of the brake disc; the moving disc can move axially along the limit post; the compression spring is arranged in the housing Inside, the axis of the compression spring is parallel to the axis of the output shaft; the compression spring can provide driving force to the moving disc to make the moving disc closely contact with the friction disc; when the solenoid is energized, the magnetic force generated in the moving disc can overcome the driving force of the compression spring to the moving disc, attract the moving disc, and separate the moving disc from the friction disc. According to a further preferred solution, the high-reliability power loss electromagnetic brake is characterized in that the friction disc is matched with the output shaft in a square profile, so that the friction disc can rotate with the output shaft and can also move along the output shaft. The axial direction of the shaft.
In summary, the above-mentioned electromagnetic power-off brake is mainly composed of an electromagnet assembly, a moving disc end cover brake assembly and an output shaft; after the brake is energized, the magnetic field force generated by the electromagnet assembly will absorb the moving disc, and the friction disc matching the profile can follow The rotating shaft rotates at high speed and is in a brake release state. After the brake is de-energized, the moving disc is pushed out by the spring, the friction disc is locked by the friction ring, and the output shaft is in a braking state. The electromagnetic power-off brake realizes the state conversion between braking and non-braking through the mechanical method of the electromagnet assembly and the spring, can work in a wide temperature range, and supports the high-speed follow-up of the rotating shaft.
