Abstract

The utility model discloses a retarding mechanism of a roller shutter door, which is connected between a main shaft of a motor and a counter shaft of the roller shutter door in a transmission way. The retarding mechanism comprises a sun gear, a planet carrier and at least one planet gear which are connected with the main shaft of the motor in a transmission way, a reducing gear connected with the counter shaft of the roller shutter door in a transmission way, transmission gears with the number the same as that of the planet gear, and connecting shafts with the number the same as that of the planet carrier, wherein the planet gear is meshed between the sun gear and the planet carrier; the transmission gear is meshed with the reducing gear; and each connecting shaft is connected with the corresponding planet gear and the corresponding transmission gear. As the retarding mechanism adopts an outer planetary reduction gear, the industrial prejudice is broken through, thus having the following advantages: 1. being simple in structure, 2. having small effectiveness loss of the motor, 3. generating large moment, and realizing the purpose of speed reduction by adopting first stage reduction, and 4 occupying small space.

Description

A kind of rolling door reducing gear
Technical field
The utility model relates to a kind of rolling door reducing gear.
Background technology
Traditional rolling door speed change gear all is to adopt the inner planet deceleration device, and this deceleration device has following deficiency: 1, moment of torsion is little, must adopt double reduction, cost height; 2, double reduction gear makes that the work energy loss of driving motor is big.
The utility model content
The utility model provides a kind of rolling door reducing gear, and its existing work of rolling door reducing gear that has overcome background technology can the big deficiency of loss.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of rolling door reducing gear, it is in transmission connection between electric machine main shaft and rolling door countershaft, this reducing gear, it comprises:
One sun gear, it has external gear;
One planet carrier that is in transmission connection electric machine main shaft, it has external gear;
At least one planetary gear, it has external gear, and, its engagement sun gear external gear and planet carrier external gear;
One reduction gearing that is in transmission connection the rolling door countershaft;
With the travelling gear of number such as planetary gear, it meshes with reduction gearing; And
With the connecting axle of number such as planetary gear, this each connecting axle connects corresponding planetary gear and corresponding travelling gear.
Among one preferred embodiment, the axis of this reduction gearing and the dead in line of sun gear.
Among one preferred embodiment, the axis of this connecting axle is parallel with the axis of sun gear.
Among one preferred embodiment, this planetary gear number is two, and these two are symmetrical arranged.
Among one preferred embodiment, offer fixing hole on the axial centre position of this dress reduction gearing, this connecting axle is hubbed on planetary gear, and the one end is fixedly attached at fixing hole, and the other end connects planetary gear
Among one preferred embodiment, this sun gear and electric machine casing are fixed together.
Among one preferred embodiment, this reduction gearing and rolling door countershaft are fixed together.
Among one preferred embodiment, this motor is a printed motor.
The technical program is compared with background technology: because the technical program adopts the outer planet deceleration device, break industry prejudice, therefore overcome the existing deficiency of background technology, and had following advantage: be 1, simple in structure; 2, the loss of motor usefulness is little; 3, generation moment is big, adopts one-level to slow down and can realize the purpose of slowing down; 4, take up room little.Because this planetary gear number is two, these two are symmetrical arranged, so equalising torque.Because this motor is a printed motor, it is little therefore to take up room.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 has illustrated the generalized section of the rolling door reducing gear of a preferred embodiment.
The specific embodiment
Please refer to Fig. 1, a kind of rolling door reducing gear 300, it is in transmission connection between the main shaft 110 and rolling door countershaft 200 of motor 100, and is installed between a procapsid 400 and the back casing 500.This procapsid 400 and back casing 500 be towards fixedlying connected, and makes to form assembly space in it.Above-mentioned reducing gear 300 is arranged within this assembly space.Among the present embodiment, this motor 100 is a printed motor.
This reducing gear 300 comprises a sun gear 320, a planet carrier 310, two planetary gears 330, a reduction gearing 340, two travelling gears 350 and two connecting axles 360.
The main shaft 110 of this motor 100 can rotate from outside to inside and put in back face-piece 500 and coaxial affixed planet carrier 310, makes main shaft 110 can drive planet carrier 310 same rotational speed when rotating.These planet carrier 310 coaxial being arranged on outside the sun gear 320.These two planetary gears, 330 symmetry engagements are arranged on external gear and and the sun gear 320 external gears engagement on the planet carrier 310.
Outside this rolling door countershaft 200 and interior can rotate put in before face-piece 400 and coaxial affixed reduction gearing 340, make reduction gearing 340 can drive rolling door countershaft 200 same rotational speed when rotating.These two travelling gears, 350 symmetries are engaged on reduction gearing 340.Offer fixing hole on the axial centre position of this travelling gear 350.
One end of this connecting axle 360 passes planetary gear 330, and is connected planetary gear 330 by bearing 361, and the other end is fixedly attached at the fixing hole of travelling gear 350.
Among the present embodiment, the axis of this reduction gearing and the dead in line of sun gear, the axis of this connecting axle is parallel with the axis of sun gear.
Motor 100 main shafts 110 drive planet carrier 310 and rotate, and drive planetary gear 330 and rotate, and planetary gear 330 rotating band nutating gears 350 rotate, and travelling gear 350 drives reduction gearing 340 and rotates, and reduction gearing 340 drives rolling door countershaft 200 and rotates.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
