Abstract
An alternating-current electro-magnet brake electromotor solves the problems that the rotary force produced by an armature disc acts on an assembling screw rod when the prior alternating-current electro-magnet brake electromotor brakes, and the assembling screw rod is easy to loosen in the effect of repeat torsion force. The electromotor comprises a casing, a front end cap, a brake end cap, a stator and a rotor, wherein one end of a motor shaft has a fan, an alternating-current electro-magnet is arranged between the fan and the brake end cap and is connected with the casing through the assembling screw rod and the brake end cap, an armature iron, an armature disc and a friction wafer are arranged between the alternating-current electro-magnet and the brake end cap, and the assembling screw rod penetrates through the armature iron. The brake electromotor is characterized in that the brake end cap is provided with a positioning stud, the other end of the positioning stud is led out through the armature disc, and the gap between the assembling screw rod and the armature disc is larger than that between the positioning stud and the armature disc. The brake electromotor has the advantages that the rotary force of the armature disc acts on the positioning stud when the electromotor brakes, solves the product quality problems caused by loosening of assembling screw rods and guarantees the reliable working.
Description
Technical field
The utility model belongs to a kind of motor, particularly a kind of alternating electromagnet brake motor.
Background technology
The revolving force that armature disc produces during existing alternating electromagnet brake motor braking acts on the assembling screw rod, and during the frequent positive and negative braking of motor, the assembling screw rod becomes flexible under the effect of repeatedly twisting resistance easily, influences the operate as normal of motor.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above that prior art exists, and provides that a kind of to avoid assembling screw rod loosening, guarantees the alternating electromagnet brake motor of reliable operation.
The utility model is achieved in that it has a casing, front end housing and braking end cap are installed at the two ends of casing, in casing, be provided with stator and rotor, the centre of rotor axle is a motor shaft, end at motor shaft is equipped with fan, outside at fan is provided with fan housing, between fan and braking end cap, alternating electromagnet is housed, alternating electromagnet connects with braking end cap and casing by the assembling screw rod, between alternating electromagnet and braking end cap, armature is housed, armature disc and friction plate, on the assembling screw rod, be set with spring, described assembling screw rod passes via armature disc, its special character is: cover at dog point positioning stud is installed, the described positioning stud other end is drawn via armature disc, and the gap between assembling screw rod and the armature disc is greater than the gap between positioning stud and the armature disc.
Advantage of the present utility model is: because positioning stud has been installed on armature disc, and the gap between assembling screw rod and the armature disc is greater than the gap between positioning stud and the armature disc, the revolving force of motor armature disc when braking acts on the positioning stud, it is loosening and the product quality problem that brings is guaranteed reliable operation to have solved the assembling screw rod.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: the 1-front end housing, the 2-casing, the 3-stator, the 4-rotor, 5-brakes end cap, the 6-friction plate, 7-armature, the 8-alternating electromagnet, the 9-spring, 10-assembles screw rod, 11-fan, 12-fan housing, 13-motor shaft, 14-armature disc, 15-positioning stud.
Embodiment
As shown in the figure, the utility model has a casing 2, by Bolt Connection front end housing 1 and braking end cap 5 is arranged respectively at the two ends of casing 2, is provided with stator 3 and rotor 4 in casing 2, the central shaft of rotor 4 is a motor shaft 13, and the two ends of motor shaft 13 are drawn by front end housing 1 and braking end cap 5 respectively.One end of motor shaft 13 is equipped with fan 11, is provided with fan housing 12 in the outside of fan 11, and fan housing 12 passes through screw attachment with braking end cap 5.Between fan 11 and braking end cap 5, alternating electromagnet 8 is housed, alternating electromagnet 8 connects with braking end cap 5 and casing 2 by assembling screw rod 10, between alternating electromagnet 8 and braking end cap 5, armature 7, armature disc 14 and friction plate 6 are housed, described armature 7 is welded on the armature disc 14, friction plate 6 is sleeved on the motor shaft 13 by the connecting mode of spline, be set with spring 9 on assembling screw rod 10, spring 9 one ends withstand on the armature disc 14 by nut location, the other end on the assembling screw rod 10.Described assembling screw rod 10 passes via armature disc 14.At braking end cap 5 positioning stud 15 is installed, positioning stud 15 other ends are drawn via armature disc 14, and the gap between assembling screw rod 10 and the armature disc 14 is greater than the gap between positioning stud 15 and the armature disc 14.
During work, after the motor outage, under the pressure of spring 9, friction plate 6 drives the double-screw bolt that is positioned when armature disc 14 rotates and lives for 15 grades, and the gap between assembling screw rod 10 and the armature disc 14 is bigger, is not subjected to the influence of braking force, has avoided assembling screw rod 15 loosening.
