Abstract
The utility model discloses a breaking device of an asynchronous machine, which relates a motor. The purpose of the utility model is to provide a breaking device of an asynchronous machine. The main technology design of the utility model is a breaking device of an asynchronous machine. A cylindrical motor rear axle is supported in a back lid hole which is fixed with the motor shell. A breaking plate hole is sliding combined with the rear axle along the axial direction and two surfaces of the breaking plate hole are respectively facing with the back lid and a keeper sheet whose circumference is uniformly distributed with an axial groove combining with an axial convex strip on an electromagnetic clutch shell hole. A coil is arranged in the hole of the electromagnetic clutch which is fixed with the back lid. A pressure spring is arranged in the center hole of the electromagnetic clutch and the center hole is corresponding to the keeper sheet. An input end of a bridge rectifier is connected with a two-phase power phase of a three-phase power and the output end of the bridge rectifier is connected with the coil of the electromagnetic clutch. The utility model is mainly used on the operation motor of the crane and also on the low speed and small load motor.
Description
Technical field:
The utility model relates to a kind of motor, particularly a kind of brake apparatus of asynchronous machine.
Background technology:
Requirement has the occasion of motor of braking function a lot, and as the operation motor of crane, the motor of the usefulness of crane operation now is a Cone-shaped electric machine, though have the function of braking, its manufacture process requirement is high and the shortcoming of axial impact arranged.
Summary of the invention:
The purpose of this utility model provides a kind of brake apparatus of asynchronous machine, and its manufacture process requirement is low and braking ability good.The technical solution of the utility model is, a kind of brake apparatus of asynchronous machine, it is characterized in that: cylindrical electrical machine rear axle rotational support is in the rear end cap hole that is connected with motor casing, brake disc hole and rear axle are slippery vertically, its both ends of the surface end face with rear end cap and armature plate respectively are relative, axial groove and the axial raised line on the electromagnetic clutch shell hole uniform on the armature plate circumference are slippery, coil places the hole of the electromagnetic clutch shell that is connected mutually with rear end cap, is provided with a compression spring in the centre bore of the electromagnetic clutch shell relative with armature plate; The input of bridge rectifier is connected with two-phase power supply in the three phase mains that motor is connected, and its output is connected with coil in the electromagnetic clutch.The outer end that the centre bore of spring is set in the electromagnetic clutch shell has a step screwed hole and bolt to match, and the end face of bolt is relative with the spring outer end.The utility model is owing to adopted the direct current line chart, and magnechuck and brake disc mechanism combine with the cylindricality motor, thereby the utility model has advantage easy to manufacture and that braking ability is good compared with the prior art.
Description of drawings:
Fig. 1 is an axial section schematic diagram of the present utility model, and Fig. 2 is the bridge rectifier electrical schematic diagram.
Embodiment:
In conjunction with above accompanying drawing the utility model is elaborated, the rear axle rotational support of cylindrical electrical machine is in the hole of rear end cap 7, the left and right sides end face of brake disc 6 end face with rear end cap and armature plate 5 respectively is relative, the brake disc hole can be that cubic hole or hexagonal hole and motor rear axle match, brake disc also can be that spline is connected with the connected mode of motor rear axle, on the circumference of armature plate uniform three mouths respectively with electromagnetic clutch shell 3 in uniform three raised lines slippery, coil 4 places in the electromagnetic clutch shell, bolt 1 matches with the screwed hole of electromagnetic clutch shell, spring 2 places the stepped hole of screwed hole interior relative with the step surface of armature plate and bolt, rear end cap and motor casing 8 are connected, and the electromagnetic clutch shell is connected mutually with rear end cap.Two inputs of bridge rectifier respectively with three phase mains that this motor is connected in B, the C of two-phase power supply be connected, its output is connected with coil.
Braking principle of the present utility model is, in the time of electric motor starting, power supply through bridge rectifier to coil for direct current, armature plate is drawn to move to right to be separated from brake disc by suction and makes the spring pressurized, brake disc is not contacted with rear end cap by responsive to axial force and dallies at this moment, thereby motor runs well.When the needs motor stops operating, cut off motor power, the cylindrical rotor 9 of motor and output shaft 10 stalls, meanwhile, the power supply of coil also is cut off, suction draws the magnetic force of armature plate to disappear, and compression spring compresses armature plate and brake disc and rear end cap, and brake disc is checked the rotator inertia of motor immediately, guarantee the safety of crane trolley, because the load of crane trolley motor is generally less, rotating speed is lower, and its moment of inertia is less, so the strength braking with compression spring is feasible, the elastic force of spring should be according to the power and the rotating speed exactness of motor, and for the motor of general crane operation usefulness, the elastic force of compression spring gets final product about 6kg.If braking effect is not good, can realize by the elastic force of bolt regulating spring.
