Utility model content
The technical problems to be solved in the utility model is: provide a kind of abrasive machine that the emery wheel of high-speed rotation can be made at once to stop operating after grinding task completes, cuts off the power supply of motor, realize reducing noise pollution, improve the life of people, work, learning quality and physically and mentally healthy level, extend the object in the service life of the bearing be arranged on motor shaft bearings at both ends position.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of magnetic powders brake abrasive machine reducing noise pollution be made up of emery wheel, support, motor, flat key, magnetic powder brake, shaft coupling, right switch, left-handed opening and protective cover, the right-hand member of support stretch out platform be provided with magnetic powder brake above.
Described magnetic powder brake forms primarily of power rotor, driven rotor, magnetizing coil and magnetic, the power rotor projecting shaft of the left end of magnetic powder brake is linked together by the right projecting shaft of the right-hand member of shaft coupling and flat key and motor, stretching out together with platform bolted of the bottom of magnetic powder brake and the right-hand member of support.
Described magnetic powder brake direct current makes excitation power supply.
Be provided with emery wheel outside the footpath of the left projecting shaft of the left end of described motor, and with packing ring, nut, emery wheel be fastened on left projecting shaft.
Described motor is together with the top bolted of support.
The outside of described emery wheel is provided with protective cover, the bottom of protective cover by connecting plate bolted on the left surface of support.
The anterior left of described support is provided with the left-handed opening of On/Off motor, and the anterior right of support is provided with the right switch of On/Off magnetic powder brake.
Usefulness of the present utility model is: due to support right-hand member stretch out platform be above provided with magnetic powder brake, magnetic powder brake forms primarily of power rotor, driven rotor, magnetizing coil and magnetic, the power rotor projecting shaft of the left end of magnetic powder brake is linked together by the right projecting shaft of the right-hand member of shaft coupling and flat key and motor, stretching out together with platform bolted of the bottom of magnetic powder brake and the right-hand member of support.When carrying out grinding with abrasive machine, open the power supply that motor connected by left-handed opening, the driven by motor emery wheel high-speed rotation of high-speed rotation carries out grinding, at this moment, and the magnetizing coil no power of magnetic powder brake, power rotor rotates together with motor shaft, due to the effect of centrifugal force, magnetic is got rid of on the inwall of power rotor, does not contact between magnetic with driven rotor, power rotor dallies, and can not affect high-speed rotation and the grinding of emery wheel; Grinding task completes, close left-handed opening cut off motor power supply after, open the power supply of right switch connection magnetic powder brake, generate an electromagnetic field after the magnetizing coil connection dc source of magnetic powder brake, magnetic forms magnetic chain under magnetic line of force effect, power rotor, driven rotor are linked up formation moment of torsion, the emery wheel of high-speed rotation is stopped operating at once, realize reducing noise pollution, improve the life of people, work, learning quality and physically and mentally healthy level, extend the object in the service life of the bearing be arranged on motor shaft bearings at both ends position.
