Abstract
The utility model relates to a kind of door-rolling machine safety clutch device, comprises platen, drive sprocket, friction plate, pressing disc, butterfly spring, round nut and lining; Upper platen is mounted on door-rolling machine motor by key; Drive sprocket, pressing disc, butterfly spring and round nut are arranged on platen successively; Friction plate is separately installed with between upper platen and drive sprocket and between pressing disc and drive sprocket; Between upper platen and the radial direction of drive sprocket, lining is installed.After there is the stuck situation of rolling door, drive sprocket required drive increases, and after it exceedes the frictional force that friction plate can provide, upper platen and pressing disc are rotated further under the effect of motor, and drive sprocket stops operating, and effectively avoids the damage of motor.
Description
Technical field
The utility model relates to a kind of door-rolling machine safety clutch device, particularly a kind of for after door-rolling machine is stuck, prevents the door-rolling machine safety clutch device of door-rolling machine motor damage.
Background technology
Electric roll-up door mechanism in long use procedure, owing to well not maintaining, may be stuck and cannot move in certain position, safety clutch device is not set in most door-rolling machine, strengthens at stuck rear motor load, door-rolling machine motor damage can be made.The utility model is exactly mainly devise a kind of structure, door-rolling machine motor can be made to dally, prevent it from damaging when load exceedes certain value.
Utility model content
It is simple that technical problem to be solved in the utility model is to provide a kind of structure, and safe and reliable door-rolling machine safety clutch device, can realize after door-rolling machine is stuck, and when motor load exceedes the frictional force of friction plate, arrangement of clutch lost efficacy, and prevented motor damage.
For solving the problems of the technologies described above, the utility model realizes as follows: a kind of door-rolling machine safety clutch device described in the utility model comprises platen, drive sprocket, friction plate, pressing disc, butterfly spring, round nut and lining; Upper platen is mounted on door-rolling machine motor by key; Drive sprocket, pressing disc, butterfly spring and round nut are arranged on platen successively; Friction plate is separately installed with between upper platen and drive sprocket and between pressing disc and drive sprocket; Between upper platen and the radial direction of drive sprocket, lining is installed.
Described upper platen and pressing disc are respectively equipped with groove and boss, and the two is by groove and boss clamping.
Good effect of the present utility model: a kind of door-rolling machine safety clutch device structure described in the utility model is simple, can be connected to easily on each door-rolling machine motor, effectively prevent motor from damaging when door-rolling machine is stuck, reliability is high, and cost is low, be suitable for extensive popularization.

Detailed description of the invention
As shown in Figure 1 and Figure 2, a kind of door-rolling machine safety clutch device described in the utility model comprises platen (1), drive sprocket (2), friction plate (3), pressing disc (4), butterfly spring (5), round nut (6) and lining (7); Upper platen (1) is mounted on door-rolling machine motor by key; Drive sprocket (2), pressing disc (4), butterfly spring (5) and round nut (6) are arranged on platen (1) successively; Friction plate (3) is separately installed with between upper platen (1) and drive sprocket (2) and between pressing disc (4) and drive sprocket (2); Lining (7) is installed between upper platen (1) and the radial direction of drive sprocket (2).
Described upper platen (1) and pressing disc (4) are respectively equipped with groove and boss, the two is by groove and boss clamping, while in driven by motor, platen (1) rotates, upper platen (1) can coordinating by groove and boss, drives pressing disc (4) to rotate.
The course of work of the present utility model:
A kind of door-rolling machine safety clutch device described in the utility model can be connected on each door-rolling machine motor easily, under normal operating condition, power passes to upper platen (1) and pressing disc (4) via motor by key transmission, by under the frictional force effect of friction plate (3) of installing respectively between upper platen (1) and drive sprocket (2) and between pressing disc (4) and drive sprocket (2) by power transmission to drive sprocket (2), thus realize the lifting of rolling door; The size of frictional force can be realized by rotational circle nut (6) adjustment butterfly spring (5) pressure to pressing disc (4), for preventing, because the thread off frictional force that causes of round nut (6) changes, using two round nuts (6) to carry out locking after adjusting frictional force size; Lining (7) can ensure that drive sprocket (2) and upper platen (1) can freely rotate after friction plate lost efficacy; After there is the stuck situation of rolling door, drive sprocket (2) required drive increases, after it exceedes the frictional force that friction plate (3) can provide, upper platen (1) and pressing disc (4) are rotated further under the effect of motor, and drive sprocket (2) stops operating, effectively avoid the damage of motor.
Some principles of work and power of a kind of door-rolling machine safety clutch device that the utility model that just explains through diagrams recited above is correlated with; be easy to carry out some amendments on this basis due to the technician concerning constructed field; therefore this manual does not really want a kind of door-rolling machine safety clutch device described in the utility model to be confined in shown or described concrete mechanism and the scope of application; therefore every corresponding modify that may be utilized and equivalent, all belong to the protection domain of the utility model patent.
