Abstract

The invention provides a wedge-block electromagnetic clutch, and belongs to the technical field of mechanical transmission. The electromagnetic clutch comprises a half-coupling, a main shaft, wedge blocks, a retainer, torsion springs, isolation blocks, a compression spring, a clutch pin, an electromagnet and an armature, wherein the axes of the half-coupling and the main shaft are superposed, the retainer is located in an annular space formed by the shaft-diameter surface of the main shaft and the inner cylindrical surface of the half-coupling, a group of the torsion springs is uniformly distributed on the annular retainer, and splayed wedge block groups formed by the wedge blocks and the isolation blocks are also uniformly distributed on the circumference of the retainer; and the clutch pin provided with the compression spring at one end penetrates through the isolation blocks and is fixedly connected to the armature, and the electromagnet movably sleeves the main shaft and is fixed to a rack. The electromagnetic clutch provided by the invention is capable of increasing the transfer torque thereof, fast in engagement reaction, capable of reducing the power and energy consumption of operating the electromagnet, compact in structure, and convenient to install.

Description

technical field [0001] The invention belongs to the technical field of mechanical transmission, and in particular relates to a wedge type electromagnetic clutch. Background technique [0002] Electromagnetic clutch is an electromechanical device that uses electromagnetic force to control the power transmission of the transmission system. It is widely used in various types of machinery to realize the distribution and control of power flow. The electromagnetic clutch in the prior art relies on the friction between the end faces of the turntable to realize the transmission of power. Known Chinese patent CN102287457A is an electromagnetic clutch, CN102242781A energy-saving electromagnetic clutch, etc. rely on electromagnetic force to attract the rotor and the armature plate to generate end surface friction to transmit power. This type of electromagnetic clutch has a compact structure, and the magnitude of the transmitted torque depends on the friction coefficient and positive p...
