CN202260842U - Speed reduction motor for automatic winding stair - Google Patents

Abstract

The utility model discloses a speed reduction motor for an automatic winding stair. The speed reduction motor comprises a motor and a reduction gearbox. The motor comprises a motor case body and an output shaft positioned in the motor case body. The front end of the output shaft is extended out of the front end face of the motor case body, and is extended into the reduction gearbox. The rear end of the output shaft is extended out of the rear end face of the motor case body. A brake is arranged on the output shaft extended out of the rear end face of the motor case body. A worm gear and a worm are arranged in the reduction gearbox, wherein the worm is matched with the worm gear, and serves as a power output shaft of the reduction gearbox. The output shaft is connected with the worm gear. The vertical reversing output of power is realized by a worm gear-worm mechanism; when the speed reduction motor is used, the power output shaft is directly connected to a device to be driven; and the brake is arranged, so that the device can be timely braked under abnormal conditions.

Description

A kind of automatic winding stair is used reducing motor

Technical field

The utility model relates to a kind of automatic winding stair and uses reducing motor.

Background technology

Automatically winding stair is used to drive the rotation of winding stair with reducing motor; Comprise motor and reduction box; Described motor comprises motor case body and the output shaft that is positioned at said motor case body; The front end of said output shaft stretches out and stretches in the described reduction box from the front end face of said motor case body, is planetary gear reduction system in the reduction box.Existing automatic winding stair is with the shortcoming that reducing motor also exists: the power output shaft of reduction box need be joined the back with changement and realized the automatic winding stair of vertical switching-over output rear drive, and the later stage installs trouble and do not have safety measure.

Summary of the invention

In order to overcome the above-mentioned deficiency of existing automatic winding stair with reducing motor, the utility model provide a kind of use safer, later stage to use to assemble easier automatic winding stair use reducing motor.

The technical scheme that the utility model solves its technical problem is: a kind of automatic winding stair is used reducing motor; Comprise motor and reduction box; Described motor comprises motor case body and the output shaft that is positioned at said motor case body; The front end of said output shaft stretches out and stretches in the described reduction box from the front end face of said motor case body, and stretch out from the rear end face of said motor case body the rear end of said output shaft, and the output shaft that stretches out the rear end face of said motor case body is provided with brake;

The worm screw of the power output shaft of the said reduction box of conduct that is provided with worm gear in the described reduction box and cooperates with described worm gear, described output shaft is connected with described worm gear.

The beneficial effect of the utility model is: the vertical switching-over output of the power of realizing through worm-and-wheel gear, the axle that only need output power during use is directly connected to be needed get final product on the drive unit, and is provided with brake, when abnormal conditions, can in time brake.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.

With reference to Fig. 1; A kind of automatic winding stair is used reducing motor; Comprise motor 1 and reduction box 2, described motor 1 comprises motor case body 3 and the output shaft 4 that is positioned at said motor case body, and the front end of said output shaft 4 stretches out and stretches in the described reduction box 2 from the front end face of said motor case body 3; Stretch out from the rear end face of said motor case body 3 rear end of said output shaft 4, and the output shaft that stretches out the rear end face of said motor case body is provided with brake 5;

The worm screw 7 of the power output shaft of the said reduction box of conduct that is provided with worm gear 6 in the described reduction box 2 and cooperates with described worm gear 6, described output shaft 4 is connected with described worm gear 6.

The utility model is exported through the vertical switching-over of the power that worm-and-wheel gear is realized, the axle that only need output power during use is directly connected to be needed get final product on the drive unit, and is provided with brake, when abnormal conditions, can in time brake.
