Abstract
The utility model discloses a coupling, it includes connecting axle, lower connecting axle to and be used for the connection to go up the jackshaft of connecting axle and lower connecting axle, the jackshaft both ends are the halfcylinder, it also is the halfcylinder with the lower connecting axle one end relative with the jackshaft to go up the connecting axle, be equipped with the rectangle recess on the jackshaft halfcylinder plane, go up the connecting axle with be equipped with the rectangle tenon that matches with the rectangle recess down on the connecting axle halfcylinder plane, and the lock is in the same place each other to form the tight fit with the axle sleeve that sets up at both ends. The utility model discloses simple structure, the preparation is easy, convenient to detach, it is good especially to connect the rigidity, and the axiality is good.
Description
Technical field
The utility model relates to a kind of shaft coupling, is specifically related to a kind of shaft coupling for vertical long shaft pump.
Background technique
Vertical long shaft pump can be used for conveying less than 55 DEG C clear water, rainwater, the iron oxide severe edema due to hypofunction of the spleen, sewage, there is the liquid such as corrosive industrial wastewater, seawater, be widely used in the industrial and mining enterprise such as sewage treatment works, power plant, Iron And Steel Plant, mine, and municipal plumbing, the engineering such as to control flood and drain flooded fields.Because the vertical shaft length of vertical long shaft pump is often beyond 10 meters, will be divided into some sections, then mountain box coupling couples together.In actual use, because vertical shaft and box coupling soak in a liquid for a long time, often there is corrosion in junction plane place, is sticked together, and causes dismounting difficulty.
Model utility content
The utility model object is the defect existed for prior art, provides a kind of shaft coupling for vertical long shaft pump.
The utility model for achieving the above object, adopt following technological scheme: a kind of shaft coupling, comprise coupling shaft, lower coupling shaft, and for connecting the jack shaft of upper coupling shaft and lower coupling shaft, described jack shaft two ends are semicylinder, and one end that described upper coupling shaft is relative with jack shaft with lower coupling shaft is also semicylinder; Described jack shaft semicylinder plane is provided with rectangular recess, and described upper coupling shaft and described lower coupling shaft semicylinder plane are provided with the rectangle tenon matched with rectangular recess, and mutually snap together, and form drive fit with the axle sleeve being arranged on two ends.
Further, described jack shaft is equal with described lower coupling shaft external diameter with described upper coupling shaft.
Further, also have Cock screw fastening between described axle sleeve and jack shaft.
Further, the width of described rectangular recess and described rectangle tenon changes between 10-20mm.
The beneficial effects of the utility model: the utility model structure is simple, make easily, and be convenient to dismounting, particularly connect good rigidly, coaxality is good.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model.
Fig. 2 is A-A sectional view of the present utility model.
Embodiment
As shown in Figure 1 and Figure 2, a kind of shaft coupling, comprises coupling shaft 6, lower coupling shaft 1, and for connecting the jack shaft 4 of upper coupling shaft 6 and lower coupling shaft 1, described jack shaft 4 two ends are semicylinder, and one end that described upper coupling shaft 6 is relative with jack shaft 4 with lower coupling shaft 1 is also semicylinder; Described jack shaft 4 semicylinder plane is provided with rectangular recess 2, described upper coupling shaft 7 and described lower coupling shaft 1 semicylinder plane are provided with the rectangle tenon 3 matched with rectangular recess 2, and mutually snap together, and form drive fit with the axle sleeve 5 being arranged on two ends.Described jack shaft 4 is equal with described lower coupling shaft 1 external diameter with described upper coupling shaft 6.In order to prevent the axial motion of axle sleeve 5, between described axle sleeve 5 and jack shaft 4, also have Cock screw 7 fastening.Described rectangular recess 2 and described rectangle tenon 3 are combined together, and mainly play the effect of axially locating, its width changes between 10-20mm.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
