Abstract
The invention relates to a sewage pump coupling with an overload protection function, and belongs to the technical field of couplings. The sewage pump coupling comprises a motor shaft and a pump shaft located on the same axis line, the motor shaft is sleeved with a thread-connection nut, and a first clutch for motor shaft power transmission is arranged at the position, located on the right side of the nut, of the motor shaft; the position, between the first clutch and the nut, of the motor shaft is sleeved with a spring, the left end of the spring abuts against the nut, and the right end of the spring abuts against the first clutch; a second clutch capable of freely rotating around the motor shaft is arranged at the position, located on the right side of the first clutch, of the motor shaft, and the second clutch is in fit connection with the first clutch through a clutch claw; the second clutch and the motor shaft are transversely positioned through balls contained in the second clutch, the left end of the pump shaft is connected to the second clutch through a spline, and the right end of the motor shaft is independently inserted into the left end of the pump shaft and is in clearance free sliding fit with the pump shaft. The sewage pump coupling is simple in structure, the stress contact area is large, the tangential force is reduced, transmission is more stable, and overload protection is achieved.
Description
Technical field
The present invention relates to a kind of sewage pump shaft joint with overload protection, belong to shaft joint technical field.
Background technique
At present, the mandrel connector connected at the Pump and Electromotor of sewage pump conveniently assembles, better be connected between axle with axle, ensure good transmission, between axle and axle, adopt rigid connection, inconvenient during assembling, stressed concentrated, if pump is blocked by a little bigger impurity, motor works on, thus causes motor or pump to damage.
Summary of the invention
According to above deficiency of the prior art; the technical problem to be solved in the present invention is: provide a kind of sewage pump shaft joint with overload protection; its structure is simple; forced contact area is large, and reduce tangential force, transmission is more steady; achieve overload protection; if avoid pump to be blocked by a little bigger impurity, motor works on, thus causes the phenomenon that motor or pump damage.
The sewage pump shaft joint of band overload protection of the present invention, comprise the motor shaft on same shaft axis and pump shaft, it is characterized in that: on motor shaft, cover has the nut be threaded, motor shaft on the right side of nut is provided with for the powerdriven clutch one of motor shaft, on motor shaft between clutch one and nut, cover has spring, spring left end withstands on nut, its right-hand member withstands on clutch one, motor shaft on the right side of clutch one is provided with the clutch two that freely can rotate around motor shaft, clutch two is connected by clutch claw and clutch one, clutch two carries out located lateral by intension ball and motor shaft, pump shaft left end by spline joint on clutch two, motor shaft right-hand member is independently inserted in pump shaft left end, be slidably matched in backlash freedom.
Conveniently process, conservative control cost, what preferred described pump shaft was arranged is external splines, and what clutch two was arranged is internal spline.
In the present invention, clutch one is provided with the following two kinds mode with coordinating of motor shaft:
One, described clutch one is that spline fitted is installed with motor shaft.
Two, described clutch one and motor shaft are that flat key coordinates and installs.
Clutch in order to ensure spring coordinates dynamics, and the natural length of preferred described spring is 100mm ~ 300mm.
Compared with prior art, the present invention has following beneficial effect:
Simple by its structure of sewage pump shaft joint of band overload protection of the present invention, forced contact area is large, reduces tangential force; transmission is more steady, achieves overload protection, is blocked if avoid pump by a little bigger impurity; motor works on, thus causes the phenomenon that motor or pump damage.Under the effect of spring and nut, axial force can be regulated.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, motor shaft 2, nut 3, spring 4, clutch 1, clutch 26, pump shaft 7, ball.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described further:
Below by way of specific embodiment, the invention will be further described, but not in order to limit the present invention, all within the present invention's spirit and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
Embodiment one
As Fig. 1 shows, with the sewage pump shaft joint of overload protection, comprise the motor shaft 1 on same shaft axis and pump shaft 6, on motor shaft 1, cover has the nut 2 be threaded, motor shaft 1 on the right side of nut 2 is provided with for the powerdriven clutch 1 of motor shaft 1, on motor shaft 1 between clutch 1 and nut 2, cover has spring 3, spring 3 left end withstands on nut 2, its right-hand member withstands on clutch 1, motor shaft 1 on the right side of clutch 1 is provided with the clutch 25 that freely can rotate around motor shaft 1, clutch 25 is connected by clutch claw and clutch 1, clutch 25 carries out located lateral by intension ball 7 and motor shaft 1, pump shaft 6 left end by spline joint on clutch 25, motor shaft 1 right-hand member is independently inserted in pump shaft 6 left end, be slidably matched in backlash freedom.
In the present embodiment, what described pump shaft 6 was arranged is external splines, and what clutch 25 was arranged is internal spline; Described clutch 1 with motor shaft 1 for spline fitted is installed; Described clutch 1 is installed for flat key coordinates with motor shaft 1; The natural length of described spring 3 is 100mm.
