Abstract

The utility model discloses an energy-saving electromagnetic clutch. The power of the existing electromagnetic clutch is constant, and the existing electromagnetic clutch can not adjust the current intensity in a coil according to the different attraction forces needed by an armature in attraction and after attraction, so a great amount of electric force are wasted. The energy-saving electromagnetic clutch of the utility model is provided with two sets of coils with different turn numbers and unequal sectional areas. According to the actual demand, the coils can be converted, the current intensity can be adjusted, and the goal of energy-saving can be achieved. The utility model has the advantages of strong applicability, small size and low cost.

Description

Energy-saving electromagnetic clutch

The utility model relates to a kind of energy-saving magnetic clutch.

Electromechanical industries are extensive use of magnetic clutch at present, magnetic clutch is when starting, need bigger electric current that armature is started and adhesive, and when armature during by adhesive, then only need less current to get final product the attracting state of holding armature, but at present the power of the magnetic clutch that uses is constant, and it can not be according to armature adjusts the electric current [strength of coil during by adhesive and by varying in size of required the suction-combining force after the adhesive, has therefore wasted a large amount of electric power.

The purpose of this utility model is to provide a kind of energy-saving magnetic clutch that can adjust electric current [strength according to the needs of working state voluntarily.

Energy-saving magnetic clutch of the present utility model comprises iron core, be wrapped in the coil on the iron core, the armature of upper end unshakable in one's determination, friction plate between iron core and the armature, the driven disc that is connected with friction plate, the electric switching mechanism that is embedded in the collector ring on the cylindrical unshakable in one's determination and forms by the slide bar, spring and the diverter switch that are contained on the iron core.Described coil is by number of turn difference, and starting coil that cross-section area does not wait and actuating coil are formed.The starting coil number of turn is few, and cross-section area is big, can produce stronger electric current during energising rapidly with the armature adhesive.The actuating coil number of turn is many, cross-section area is little, can produce the adhesive of less current holding armature during energising, the conversion of starting coil and actuating coil, be to realize by slide bar, spring and the diverter switch that is installed on the iron core, slide bar links to each other with the movable contact of diverter switch, and armature promotes the slide bar motion during by adhesive.Realize changing the function of magnetic clutch electric current [strength.

Great advantage of the present utility model is an obvious energy conservation, and in addition, the utility model applicability is strong, and volume is little, cost is low.
