Abstract
The utility model discloses a novel door opening clutch, and relates to the technical field of a door opening machine. The door opening clutch comprises a machine shell and an output cover covering the machine shell, wherein an output shaft is arranged in the middle of the output cover, and a guide base is fixed at one end, in the machine shell, of the output shaft. A rotating shaft capable of rotating relative to the guide base is arranged between the guide base and the inner wall of the machine shell. A bearing is fixed in the middle of the rotating shaft, two sides of the bearing are respectively provided with a worm gear and a rotor, the worm gear and the rotor are fixedly connected, the worm gear is provided with a worm rod matched with the worm gear to transmit, and a clutch pedal is arranged between the guide base and the rotor. The novel door opening clutch has the advantages of being stable in transmission process due to transmission of the worm gear and the worm rod, and high in sensitivity and safety.
Description
[technical field]
The utility model relates to a kind of clutch of switch gate, and in particular, the utility model relates to a kind of clutch that opens the door by worm gear and worm screw precision drive.
[background technology]
Existing automatic rolling door is comprised of control device, aggressive device, transmission device, track, door and monolock clutch, its transmission device is generally chain drive, driving chain driving gate body motion by monolock clutch connection door body, door body both sides are placed on the body slideway by pulley.During the overhead door body, the operator starts aggressive device by control device, drives a body lifting through transmission device, when in door body motion process, having a power failure suddenly, can pass through cut-off clutch, make a body break away from chain gearing, can open the door, close the door by hand moving door body like this.The sensitivity of this drive mechanism is not high and safety factor is not high, the stuck imagination can occur, and effect is not fine.
[utility model content]
The purpose of this utility model is effectively to overcome the deficiency of above-mentioned technology, and a kind of clutch that opens the door that carries out transmission by worm gear and worm screw is provided, and the utlity model has higher sensitivity and safety factor.
The technical solution of the utility model is achieved in that it has casing and covers with lid to the output on casing, described output lid middle part is provided with a force-output shaft, its improvements are: the end that described force-output shaft is arranged in the casing is fixed with a guide bracket, being provided with one between this guide bracket and the casing inner wall can be with respect to the turning cylinder of guide bracket rotation, be fixed with a bearing on this turning cylinder medium position, be respectively equipped with a worm gear and a rotor in described bearing both sides, and described worm gear and rotor are bolted to connection; Described worm gear has the worm screw of the transmission that matches with it, is provided with clutch plate between described guide bracket and rotor;
In the said structure, be equipped with a line seat on the described rotor, this line seat is bolted on casing inside;
In the said structure, between described turning cylinder and the guide bracket, be provided with bearing between the inwall of turning cylinder and casing;
In the said structure, fixed by bolt between described output lid and the casing;
In the said structure, described casing is aluminium alloys with the material of output lid.
The beneficial effects of the utility model are: the utility model rotates by the driven by motor force-output shaft, thereby driving guide bracket together rotates, effect by clutch plate, rotor driven rotates at turning cylinder, and then the drive worm gear rotates, worm gear has the worm screw of the transmission that matches with it, the rotation of worm gear is converted into the rotation of worm screw, when the needs worm screw stops operating, and motor can by the effect of clutch plate, be separated guide bracket and rotor during still for rotary state, rotor namely stops operating, and worm screw also stops operating immediately; This drive mechanism, transmission process is steady, and is highly sensitive, safety factor is high, is a kind of clutch that opens the door of precision drive.
[description of drawings]
Fig. 1 is schematic cross-section of the present utility model.
[specific embodiment]
The utility model will be further described below in conjunction with drawings and Examples.
With reference to shown in Figure 1, the utility model has disclosed a kind of novel clutch that opens the door, it has casing 1 and the output lid 2 that covers at casing 1 one ends, output is covered 2 and is fixed on the casing 1 by bolt 16, output is covered 2 middle parts and is provided with a force-output shaft 3, this force-output shaft 3 and output are provided with rolling bearing 4 between covering 2, therefore force-output shaft 3 can cover 2 rotations with respect to output, and this force-output shaft 3 is arranged on the end in the casing 1 and is fixed with a guide bracket 5, being provided with one between this guide bracket 5 and casing 1 inwall can be with respect to the turning cylinder 6 of guide bracket 5 rotations, between turning cylinder 6 and the guide bracket 5, be provided with bearing 7 between turning cylinder 6 and casing 1 inwall, these turning cylinder 6 medium positions also are provided with bearing 8, the both sides of bearing 8 are respectively arranged with worm gear 9 and rotor 10, and worm gear 9 is fixedly connected with by bolt 11 with rotor 10, and worm gear 9 is provided with the worm screw 12 of the transmission that matches with it, is provided with clutch plate 13 between described guide bracket 5 and rotor 10, be equipped with a line seat 14 on the rotor 10, this line seat 14 is fixed on casing 1 inside by bolt 15.
In said structure, force-output shaft 3 connects with the output shaft of motor, the guide bracket 5 that rotarily drives by motor together rotates, guide bracket 5 is by the effect of clutch plate 13, and rotor driven 10 rotates around turning cylinder 6, because turbine 9 is fixedly connected with by bolt 11 with rotor 10, therefore, turbine 9 also together rotates, and turbine 9 has the worm screw 12 of the transmission that matches with it, thereby realizes 12 rotations of driven by motor worm screw; When needs worm screw 12 stops operating, effect that can be by clutch plate 13, so that rotor 10 does not together rotate with guide bracket 5, worm screw 12 can stop operating, this drive mechanism, transmission process is steady, and is highly sensitive, safety factor is high.
Described above only is preferred embodiment of the present utility model, and above-mentioned specific embodiment is not to restriction of the present utility model.In technological thought category of the present utility model, various distortion and modification can appear, and the retouching that all those of ordinary skill in the art make according to above description, revise or be equal to replacement, all belong to the scope that the utility model is protected.
