Embodiment Construction

[0020] Please check figure 1 , the reduction transmission mechanism of the rolling door machine, it is connected between the motor and the actuator, it includes a base 100, a rigid wheel 200 fixed on the base 100, a flexible wheel 300, a power shaft 400 and an output shaft 500. 700 in the figure is the casing of the motor.

[0021] In this embodiment, the base 100 may generally include an output end body and an input end cover that can be relatively butted together, and a stepped hole 110 is disposed inside the output end body.

[0022] The rigid wheel 200 is fixedly connected to the inner rotary surface of the large hole of the stepped hole 110 of the base 100, and the inner rotary surface of the rigid wheel 200 is provided with inner gear teeth, and the number of teeth of the inner gear teeth is N2. In this embodiment, the material of the rigid wheel 200 is, for example, No. 45 steel. In this embodiment, the N2 may be 202.

[0023] The motor is fixed relative to the base...

Abstract

The invention discloses a reduction transmission mechanism of a rolling shutter door machine, which comprises a base, a rigid wheel fixedly arranged on the base, a flexible wheel and a power shaft, wherein the inner revolution surface of the rigid wheel is provided with inner wheel teeth, the outer revolution surface of the flexible wheel is provided with outer wheel teeth, the power shaft is coaxially and fixedly connected with a cam, and the can is provided two farthest ends; the flexible wheel is arranged in the rigid wheel, the inner wheel teeth can be matched with the outer wheel teeth, and the number of the outer wheel teeth of the flexible wheel is less than the number of the inner wheel teeth of the rigid wheel; the cam is arranged in the flexible wheel, a plurality of needle rollers are annularly arranged at intervals between the cam and the flexible wheel, and the needle rollers are located by a flexible holder; and the two farthest ends of the cam abuts on the flexible wheel by means of the needle rollers, and the abutted part of the flexible wheel is subjected to elastic deformation, so that the outer wheel teeth at the abutted part are meshed with the inner wheel teeth. The invention has the following advantages: 1, the reduction transmission mechanism can realize the reducing purpose by using only one reduction system, and has the characteristics of large reduction ratio, simple structure and small occupied space; 2, the traditional brake housing can be omitted; and 3, the processing cost is low.

Description

technical field [0001] The invention relates to a deceleration transmission mechanism of a rolling door machine, in particular to a deceleration transmission mechanism of a rolling door machine which takes up little space, has a simple structure and low manufacturing cost. Background technique [0002] The existing reduction transmission mechanism of a rolling shutter machine comprises a base, a reduction box, a brake box, a power shaft and an output shaft. The transmission of the reduction box is connected between the power shaft and the output shaft, and it includes a multi-stage reduction train, and each of the reduction trains includes a small gear and a large gear, and the large gear meshes with the pinion. The brake box is transmission-connected to the output shaft. The existing deceleration transmission mechanism has the following disadvantages: 1. The deceleration is realized through the cooperation of large and small gears, and the deceleration ratio is small. Gene...
