German BLEICHERT brake BLEICHERT model BLEICHERT price

BLEICHERT brake is a connector that transmits torque from the driving side to the driven side. It can be freely engaged, disengaged, or braked as needed. It offers advantages such as compact structure, simple operation, sensitive response, long service life, reliable use, and ease of remote control. Electromagnetic brakes are ideal automation actuators in modern industry, mainly serving to transmit power and control motion in mechanical transmission systems.

BLEICHERT brake introduction

The electromagnet is a key component of the electromagnetic brake, having a significant impact on the performance stability and reliability of the electromagnetic brake. When a vehicle uses the brakes continuously while descending a long slope or during emergency braking at high speed, the temperature of the brake working components rises sharply. When the temperature reaches a certain level, the friction coefficient of the brake friction pair decreases due to mechanical, physical, and chemical factors, leading to a decline in braking efficiency. This phenomenon is known as thermal fade of braking efficiency. The resistance to thermal fade is one of the important indicators for evaluating brake performance. The following analysis uses the finite element method to analyze the temperature field of the electromagnet and friction ring at various stages during descent, and verifies the accuracy of the analysis model and method through experiments.

BLEICHERT brake working principle

The friction ring rotates together with the brake drum. The electromagnet and the drive lever are connected by a retaining ring. At the start of braking, the controller sends a braking signal, energizing the electromagnet to generate electromagnetic attraction, which adsorbs onto the friction ring. Since the electromagnet is constrained by the drive lever, it slides relative to the friction ring. The friction force acting on the electromagnet drives the connected drive lever to rotate around the fulcrum. The driven end of the lever opens the two friction shoes of the brake and presses them against the brake drum, generating braking torque. At the end of braking, the electromagnet is de-energized, the attraction and friction forces disappear, and under the pull of the return spring, the friction shoes move away from the brake drum, releasing the brake. Electromagnetic brakes are ideal automation actuators in modern industry, mainly serving to transmit power and control motion in mechanical transmission systems. They offer advantages such as compact structure, simple operation, sensitive response, long service life, reliable use, and ease of remote control. They are mainly matched with series motors. They are widely used in machinery for metallurgy, construction, chemical industry, food, machine tools, stages, elevators, ships, packaging, etc., as well as in situations requiring braking during power failure (safety).

BLEICHERT brake precautions for use

1) Use the electromagnetic brake in a condition completely free of moisture, oil, etc. If the friction parts are contaminated with moisture or oil, the friction torque will be greatly reduced, and braking sensitivity will deteriorate. To avoid these situations during use, please install a cover. 2) When used in dusty environments, please place the entire brake in a box. Electromagnetic brakes below 60KGM can use the vertical type, and even higher models can use it. 3) Please use the specified dimensions for the long shaft used to install the brake. Please use one of the specified keys for the installation shaft. 4) Considering factors such as thermal expansion, please keep the thrust on the installation shaft below 0.2MM. 5) During installation, please adjust the attraction gap on the machine to within plus or minus 20% of the specified value. 6) Please keep the bracket light; do not subject the brake bearing to excessive pressure. 7) For assembly screws, please use spring washers, adhesives, etc., to prevent loosening. 8) While maintaining the lead wires using the frame on the mechanical side, ensure secure connections using terminal blocks, etc.
