Abstract
The utility model relates to a drum-shaped gear coupling with an overload protecting mechanism. The utility model is formed by that an overload protecting mechanism for a safety disk is additionally arranged in a common drum-shaped gear coupling. The protecting mechanism is composed of a tabular safety disk and a flange sleeve shaped safety disk, wherein, the tabular safety disk is fixedly connected with a drum-shaped gear half coupling, the flange sleeve shaped safety disk is fixedly connected with another drum-shaped gear half coupling, and the tabular safety disk is fixedly connected with the flange sleeve shaped safety disk through a short shaft structure and a securing pin. When overload occurs, the securing pin is cut off by torque transferred by the coupling, and the two half couplings are disengaged from each other, and thereby, motors and working devices are protected, the coupling is also protected, and loss caused by overload is preferably avoided.
Description
The utility model is a kind of crown gear coupling that has overload protection mechanism, and it not only has the advantage of crown gear coupling, also has the overload protection function.
In prior art, common crown gear coupling can't be protected motor and transmission device when overload, and the loss that the overload fault is brought is inevitable.If increase the design parameter of motor and transmission system safety coefficient for fear of the overload fault, certainly will will improve cost and its utilization ratio of reduction of equipment, thereby cause the increase of cost of production.Therefore, this is not a good solution.
The purpose of this utility model is at the problem in the prior art, and a kind of crown gear coupling that has overload protection mechanism is provided, the loss that the fault of avoiding overloading under the condition that does not increase cost of production is brought.
For achieving the above object, solution of the present utility model is as follows: it has two crowned teeth half-couplings and connect firmly a flat burst disk on the connection end face of a crowned teeth half-coupling, on the connection end face of another crowned teeth half-coupling, connect firmly a flange shell-like burst disk, the center of described flat burst disk is provided with a minor axis that vertically stretches out from card, described flange shell-like burst disk, and connects firmly together by safety pin and flat burst disk on this minor axis by Bearing Installation.
By above-mentioned solution as can be seen, the utility model has been set up burst disk overload protection mechanism in common crown gear coupling.During overload, the safety pin that connects two burst disk is cut off by the moment of torsion that coupling transmits, and at this moment, is equivalent to two half-couplings and throws off, and then working machine quits work, and motor idle running.Owing to be provided with the minor axis structure between two burst disk, institute can not cause the damage of coupling so that this coupling still remains on the same axis when throwing off, and changes safety pin again and just can recover to connect.So both protect motor and working equipment, also protected coupling, thus the loss of having avoided overload to bring preferably.Moreover, adopt this kind structure, also can be optimized design to the crowned teeth parameter and the material of this coupling, make this coupling have the bearing capacity height, characteristics in light weight, that volume is little.Simultaneously, the utility model unites two into one crown gear coupling and overload protection mechanism, also has advantage reasonable in design, simple in structure, compact, that reliability is high.
Describe structure of the present utility model and working principle in detail according to embodiment below.
Fig. 1, the utility model embodiment's 1 structural drawing.
Fig. 2, the utility model embodiment's 2 structural drawing.
Referring to Fig. 1, described crown gear coupling is made up of two crowned teeth half-couplings 1,2, half-coupling 1 or 2 by external toothing 1.1 or 2.1 and ring gear 1.2 or 2.2 constitute; On the connection end face of half-coupling 1, connect described flat burst disk 3, on the connection end face of half-coupling 2, connect described flange shell-like burst disk 5 by clamping bolt 9 by clamping bolt 8; Be provided with described minor axis 6 at the center of flat burst disk 3, described flange shell-like burst disk is installed on this minor axis by bearing 7, and is bound up by safety pin 4 and flat burst disk; Described safety pin circumferentially is symmetrical arranged two along burst disk.Its working principle is: in normal operation, driven by motor half-coupling 1 is passed to flat burst disk 3 to moment of torsion, passes to half-coupling 2 by safety pin 4 and flange shell-like burst disk 5 again, thus driven gear case or working machine work; During overload, transmitting torque between two half-couplings 1,2 increases, make the also corresponding increase of shearing force of 3,5 pairs of safety pins 4 of burst disk, when surpassing the shearing force of safety pin permission, safety pin 4 is cut off, and then working machine quits work, and motor still drives half-coupling 1 burst disk 3, minor axis 6 and bearing 7 idle running, at this moment, because the support of minor axis 6 and bearing 7 still remains on the same axis two burst disk.
Referring to Fig. 2,, can adopt the structure shown in the figure for satisfying the requirement of axial dimension.Connect a major axis 10 by described two crowned teeth half-couplings 1,2, flange half-coupling 11 of connection end face first line of a couplet knot at crowned teeth semijoin device 2, be used to connect gear-box or working machine, in the blue shell-like burst disk 12 of the connection end face first line of a couplet connection of another crowned teeth half-coupling 1, described flat burst disk connects firmly the connection end face that is used to connect the flange half-coupling 13 of motor shaft at another.The structure of described flat burst disk is identical with Fig. 1, and described flange shell-like burst disk is made up of flange stock 12.1 and short sleeve 12.2 sockets.Interconnecting of two burst disk is identical with Fig. 1.During proper functioning, driven by motor flange half-coupling 13 and flat burst disk 3 pass to flange half-coupling 11 by safety pin 4 and flange shell-like burst disk 5 and major axis again and drive working machine work; During overload, safety pin is cut off, and working machine quits work, and driven by motor half-coupling 13, burst disk 3, minor axis 6 and bearing 7 idle running.
