German inmess brake inmess model inmess price

inmess brakes are devices that decelerate, stop, or maintain the stopped state of moving parts (or machinery). They are mechanical components that stop or decelerate moving parts in machinery. Commonly known as brakes. Brakes mainly consist of a frame, braking elements, and operating mechanisms. Some brakes are also equipped with automatic adjustment devices for braking element clearance. To reduce braking torque and structural size, brakes are usually installed on the high-speed shaft of the equipment, but for large equipment with high safety requirements (such as mine hoists, elevators, etc.), they should be installed on the low-speed shaft near the working part of the equipment.

inmess Brake Introduction

The electromagnet is a key component of electromagnetic brakes, significantly affecting their performance stability and reliability. When a vehicle uses brakes continuously while descending a long slope or during emergency braking at high speed, the temperature of the brake's 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 called thermal fade of braking efficiency. The resistance to thermal fade is one of the important indicators for evaluating brake performance. The following analyzes the temperature field of the electromagnet and friction ring at various stages during descent using finite element analysis, and verifies the accuracy of the analysis model and method through experiments.

inmess Brake Working Principle

The friction ring rotates together with the brake drum, and the electromagnet is connected to the drive lever via a retaining ring. At the start of braking, the controller sends a braking signal, energizing the electromagnet, which generates electromagnetic attraction and adheres to the friction ring. Since the electromagnet is constrained by the drive lever, it slides relative to the friction ring, and the friction force acting on the electromagnet drives the connected drive lever to rotate around the pivot point. 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 an ideal automation actuator in modern industry, mainly serving to transmit power and control motion in mechanical transmission systems. They have advantages such as compact structure, simple operation, sensitive response, long life, reliable use, and ease of remote control. They are mainly matched with series motors. Widely used in metallurgy, construction, chemical, food, machine tools, stage, elevator, ship, packaging, and other machinery, as well as in situations requiring braking during power failure (safety).

inmess Brake Usage Precautions

1) Use the electromagnetic brake in a condition completely free of moisture, oil, etc. If the friction surface is 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. 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) Keep the bracket light; do not subject the brake bearings 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.
