Abstract
The utility model discloses an overloading protective coupling, which comprises a loading coupling sleeve, a motor coupling sleeve and a middle coupling sleeve with an unloading device. The loading coupling sleeve and the middle coupling sleeve are connected with a coupling bolt via a pin, the middle coupling sleeve is connected with the motor coupling sleeve via an overloading protective pin, a flange fixedly connected with the motor coupling sleeve and a motor shaft is mounted inside the middle coupling sleeve, and a bearing is mounted on the flange to perform unloading protective effect. The diameter and quantity of the overloading protective pin can be determined according to load of overloading protection. By adopting the scheme, the coupling can ensure stable and reliable power transmission under normal working state; when the load overloads or exceeds load set in the design, the overloading protective pin is broken to interrupt power transmission under the action of a cutting force, a motor idles to avoid being damaged, and the broken overloading protective pin can be disassembled conveniently and rapidly through process screwed holes and limit screws on the middle coupling sleeve and a left positioning sleeve.
Description
Technical field
The utility model relates to a kind of coupling, is a kind of overload protection coupling specifically.
Background technique
Coupling is two axles that are used for connecting in the different institutions, be driving shaft and driven shaft, making it the mechanical parts of common rotation with transmitting torque, is that the engineering goods axle is a coupling member the most frequently used in the transmission, and power engine mostly links by means of coupling and working machine.In construction machinery industry, in power transmission process, overload protection is very important, and the coupling that therefore is used for the transmission of power overload protection is widely used.The structure of overload protection coupling is that power engine joint sleeve and working machine joint sleeve connect by safety pin at present; when actual load surpasses qualification load; shear pin breakage; so just blocked the transmission of power; thereby the unlikely damage of remaining part of protection machine; but shortcoming is: because power engine work principle and structure is different; its mechanical property difference is very big; the running that has is steady; impact is arranged during the running that has; transmission system is formed the influence that does not wait; along with the vibrations that produce in the machine operation procedure; safety pin might shake, and coupling does not just have the effect of safety protection when transshipping like this, and large-scale machinery equipment is adjusted difficulty of diaxon centering; therefore it is convenient that used overlond coupling just needs to change easily damaged parts; but existing overload protection coupling must be pulled down coupling new safety pin could be installed after shear pin breakage, makes operation inconvenience but also may influence the use of machinery equipment like this.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of overload protection coupling to be provided, it under normal operative condition, can guarantee transmission of power steadily, reliable; When the load overload, can throw off transmission of power, motor is played a protective role.
Technological scheme: in order to solve the problems of the technologies described above; the technical solution of the utility model is: a kind of overload protection coupling; it comprises load joint sleeve, motor joint sleeve, middle joint sleeve; wherein the load joint sleeve is connected with attachment bolt by pin with middle joint sleeve; middle joint sleeve is connected by the overload protection pin with the motor joint sleeve, and the flange of fixedlying connected with motor joint sleeve, motor shaft is installed in middle joint sleeve.Determine the diameter and the quantity of overload protection pin according to the load of overload protection.Adopt this scheme, under normal operative condition, can guarantee the steady, reliable of transmission of power; When the load overload was promptly gone up the load of defined above design, the overload protection pin produced fracture and has promptly interrupted transmission of power under shear action, and motor idle running does not make motor destroyed.
In order to strengthen the tightness that middle joint sleeve is connected with the motor joint sleeve; and the overload protection pin of dismounting that can be easily and fast fracture; be respectively equipped with left setting sleeve, right setting sleeve at two ends, the overload protection pin left and right sides, and by the fastening overload protection pin of axial limiting screw.
In order to make coupling more steady in power transmission process, when rupturing, the overload protection pin plays the off-load effect, the shaft block ring of bearing and rigid bearing is housed on described flange.
Described bearing is two roller bearings, and cone spacer and outer ring spacer are installed between two roller bearings, has increased the contact width of two roller bearings like this, increases the off-load effect.
Beneficial effect: compared with prior art, the utility model has the advantages that transmission of power is steady when running well, when the load overload, can throw off transmission of power, make motor idle running, load off-load, motor is played a protective role; And the overload protection pin of dismounting that can be easily and fast fracture.
