Technical field
The utility model relates to a kind of Novel conical rotor braking motor.
Background technology
The motor that bore of stator and rotor profile are all tapered.It has the ability of power failure self-retention, is widely used in the hoisting equipment such as electric block, hoist engine, and the brake apparatus of conical rotor motor is made up of the braking ring on the tripping spring be enclosed within rotor, fan braked wheel and end cap.Motor stator of the prior art and rotor are all isodiametric cylindrical-shaped structures, during installation, rotor is directly inserted in motor stator, once small deflection appears in rotor in the process of installation, just easily make to produce collision between rotor and stator, easily motor is scrapped.Existing motor can not depart from braking at once to electric energy and rotate simultaneously, and also can not brake at once after power-off, namely rotor can not stop operating instantaneously, and large by the impact of networking change in voltage and load variations, and braking effect is poor, there is potential safety hazard.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, there is provided a kind of staring torque large, impact by networking change in voltage and load variations is little, not only can complete turning effort simultaneously, also have the Novel conical rotor braking motor of the effect of brake.
The utility model solves the technical scheme that its technical problem adopts: a kind of Novel conical rotor braking motor, there is body, the middle position of described body is provided with rotor, the rear and front end of body is provided with front end housing and rear end cap, front end housing place is provided with bearing, the middle position of rotor is provided with stator, the right side axle head of rotor is provided with axle sleeve, axle sleeve is provided with braked wheel, braked wheel is fixing by locking nut locking, rear end cap and fan housing are connected and fixed, thrust bearing is provided with between rear end cap and rotor, thrust bearing is fixed by support set, stage clip is provided with between support set and stator, the top of body is provided with terminal box.
Further, the axial movement value of described rotor is 1.5-3mm, and rotor is tightly pressed on braking wheel hub with fan braked wheel, and frictionally square makes motor braking, the axial shifting amount of rotor, within the scope of 1.5 ~ 3mm, excessive or too smallly all to regulate.
Further, described front end housing and rotor junction are provided with oil sealing, improve sealing property and the anti-dust performance of rotor and front end housing, reduce coefficient of friction, improve useful life.
Further, described braked wheel is provided with braking ring, braking ring adopts elastomeric material to make, the braking force of conical rotor machine braking ring is adjustable, after the braking ring wearing and tearing on braking wheel hub, regulates and brake the braking force between wheel hub, ensure that brake is reliably sensitive, when braking the braking ring (rubber) on wheel hub and wearing up to the limit, namely again should change braking ring, improve security performance.
The beneficial effects of the utility model are: the utility model structure is simple, staring torque is large, impact by networking change in voltage and load variations is little, not only can complete turning effort, also have the effect of brake, the braking force of conical rotor machine braking ring is adjustable simultaneously, ensure that brake is reliably sensitive, improve security performance, long service life, reduces costs.
