German stearns clutch stearns model stearns price

stearns clutch refers to a friction clutch where clamping force is generated by electromagnetic force. Due to its ability to enable remote operation, low control energy consumption, ease of machine tool automation, fast response, and simple structure, it has gained widespread application.

stearns clutch introduction

Electromagnetic clutches, also known as electromagnetic couplings, are electromechanical connectors that apply the principle of electromagnetic induction and friction between internal and external friction plates. They allow two rotating components in a mechanical transmission system to engage or disengage while the driving component continues to rotate, functioning as an automatic electrical device. Electromagnetic clutches can be used to control machine starting, reversing, speed regulation, and braking. They feature simple structure, fast response, low control energy, and ease of remote control. Despite their compact size, they can transmit high torque. When used for braking control, they offer rapid and smooth braking. Therefore, electromagnetic clutches are widely used in various machining tools and mechanical transmission systems. The function of an electromagnetic clutch is to transmit torque (or power) from the driving shaft to the driven shaft. It is widely used in various mechanisms (such as transmission mechanisms in machine tools and various electric mechanisms) to achieve functions such as rapid starting, braking, forward/reverse rotation, or speed regulation. Since electromagnetic clutches facilitate remote control and are much easier to operate compared to mechanical, hydraulic, or pneumatic clutches, they are important components in automatic control systems.

stearns clutch features

1) High-speed response: As it is a dry type, torque transmission is fast, enabling convenient operation. 2) High durability: Good heat dissipation and the use of premium materials ensure 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: Plate springs are used, preventing loosening even under strong vibration, ensuring good durability.

stearns clutch installation precautions

1) Please use dry electromagnetic clutches in conditions completely free of moisture and oil. If the friction surfaces are contaminated with moisture or oil, friction torque will be significantly reduced, and clutch sensitivity will decrease. To avoid these issues, install protective covers. 2) Use protective covers when operating in dusty environments. 3) For the long shaft dimension used to install the clutch, please use specifications conforming to JIS0401 H6 or JS6. For the key used on the installation shaft, please use one of the types specified by JIS B1301-1959. 4) Considering thermal expansion and other factors, please keep the thrust on the installation shaft below 0.2MM. 5) During installation, adjust the attraction gap on the machinery to within plus or minus 20% of the specified value. 6) Keep the bracket lightweight; do not subject the clutch bearing to excessive load. 7) For assembly screws, use spring washers, adhesives, or other methods to prevent loosening. 8) While securing the lead wires using the frame on the mechanical side, ensure solid connections using terminal blocks or similar components.
