German HARTMANN & KONIG clutch, HARTMANN & KONIG models, HARTMANN & KONIG pricing

HARTMANN & KONIG clutches refer to friction clutches where the clamping force is generated by electromagnetic force. Due to the ability to achieve remote operation, low control energy, ease of implementing machine tool automation, fast action, and simple structure, they are also widely used.

HARTMANN & KONIG clutch introduction

Mechanical components that stop or decelerate moving parts in machinery. Commonly known as brakes. Brakes mainly consist of a brake frame, braking elements, and operating devices. Some brakes are also equipped with automatic adjustment devices for braking element clearance. To reduce braking torque and structural dimensions, 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. Some brakes have been standardized and serialized, and are manufactured by specialized factories for selection. They are mainly matched with series motors. Widely used in metallurgy, construction, chemical industry, food, machine tools, stages, elevators, ships, packaging and other machinery, as well as in situations requiring braking during power failure (safety). The resistance torque that must be applied to stop or decelerate mechanical rotating parts is called braking torque. Braking torque is the basis for designing and selecting brakes, and its magnitude is determined by the type of machinery and work requirements. The performance of friction materials (braking elements) used in brakes directly affects the braking process, and the main factors affecting their performance are operating temperature and temperature rise rate. Friction materials should have a high and stable coefficient of friction and good wear resistance. Friction materials are divided into metal and non-metal categories. The former commonly includes cast iron, steel, bronze, and powder metallurgy friction materials, while the latter includes leather, rubber, wood, and asbestos.

HARTMANN & KONIG clutch features

1) High-speed response: Because it is a dry type, torque transmission is fast, allowing for convenient operation. 2) Strong durability: Good heat dissipation, and the use of advanced materials ensures high durability even under high-frequency, high-energy usage. 3) Easy assembly and maintenance: The magnetic coil is stationary and housed within ball bearings, so there is no need to remove the core or use carbon brushes, making it simple to use. 4) Reliable operation: Uses plate springs, which do not loosen even under strong vibration, offering excellent durability.

HARTMANN & KONIG clutch maintenance

To ensure uninterrupted operation of the electromagnetic clutch, regular maintenance and care are required: 1) Frequently add lubricant to the moving parts of the electromagnetic clutch. 2) Regularly check the length of the armature stroke. During clutch operation, the armature stroke length will increase due to wear on the friction surfaces. When the armature stroke length does not reach the normal value, adjustments must be made to restore the minimum gap between the braking surface and the rotor. If the armature stroke length increases beyond the normal value, the suction force may be significantly reduced. 3) If worn braking surfaces are replaced, the minimum gap between the braking surface and the rotor should be readjusted appropriately. 4) Frequently check the tightness of bolts, especially tightening the bolts of the electromagnet, the bolts connecting the electromagnet to the housing, the yoke bolts, the electromagnetic coil bolts, and the wiring bolts. 5) Regularly inspect the mechanical wear of moving parts and remove dust, lint, and dirt from the surface of electromagnetic components.
