Abstract
The utility model relates to a double-clip type solid coupling which comprises two half-couplings, a semi-ring and gap plates, wherein the semi-ring is installed on a water pump shaft, the inner surface of each half-coupling comprises a half-coupling matching surface, a water pump shaft installation surface and a motor shaft installation surface, the water pump shaft installation surface and the motor shaft installation surface are concentric cylindrical surfaces, and the diameter of axle of the water pump shaft installation surface is smaller than that of the motor shaft installation surface. A threaded hole is formed in each half-coupling, and a gap plate is placed on the side of each water pump shaft installation surface. A bolt penetrates through the gap plates to connect the two half-couplings in a screwing mode. An installation gap exists between the two half-couplings. The double-clip type solid coupling is convenient to install and dismantle, low in machining requirements, low in maintaining cost, good in coaxiality, and good in applicability.
Description
Technical field
The utility model relates to vertical and the horizontal single-stage single-suction centrifugal pump coupling, is specifically related to a kind of wafer type rigid coupling.
Background technique
The used rigid coupling great majority of centrifugal pump are case butt coupling at present, and it is that the coupling sleeve part is connected in the friction welding mode with water pump spindle.Coupling sleeve has tapped hole, and inside has keyway.This coupling mounting type is: after Water pump head installs, the motor shaft of fitting key is installed in the sleeve, behind the location positioning, screws tight fixed bolt.In motor operation course, this coupling can be delivered to moment of torsion on the water pump spindle from motor shaft, and is simple in structure, compact to design.But there is following problem in this kind coupling: 1. water pump spindle and coupling are welded as a whole, no matter coupling or water pump spindle go wrong, whole parts all must be scrapped.2. bond length changes according to motor producer is different from the axial end position on the motor shaft, and screw position might not conform to the motor key and causes coupling mechanism force inadequate.3. higher to the motor shaft requirement on machining accuracy, the microlesion on motor shaft surface all might cause the difficulty of installation, and, any motor shaft micro-strain that when Cock screw is installed, causes, the inconvenience in the time of all might causing dismounting, even affect coaxality.
The model utility content
The purpose of this utility model is for deficiency of the prior art, and a kind of easy installation and removal, processing request is low, maintenance cost is low, coaxality is good, applicability is good wafer type rigid coupling are provided.Need to solve following problem for this reason: at first, how satisfy simple for structure in, guarantee that moment of torsion can pass to water pump spindle from motor shaft; The 2nd, how to guarantee the coaxality of water pump spindle and motor shaft; The 3rd, how can when pump maintenance, satisfy dismounting with again easy for installation, and when coupling or water pump spindle go wrong separately, need not integral replacing, save maintenance cost; The 4th, how to satisfy the motor that adapts to different manufacturers, and need not to redesign coupling.
For finishing above-mentioned purpose, the technical solution adopted in the utility model is: the wafer type rigid coupling comprises two half-couplinves, semi-ring and antipad; Described semi-ring is installed on the water pump spindle; Described two half-coupling internal surfaces comprise that shaft coupling fitting surface, water pump spindle are installed the surface and motor shaft is installed the surface, and it is the concentric column surface that water pump spindle installation surface and motor shaft are installed the surface, and water pump spindle is installed the surperficial diameter of axle and less than motor shaft the surperficial diameter of axle is installed; Be provided with tapped hole on described two half-couplinves, be sidelong and put antipad in that surface one is installed by water pump spindle, bolt passes antipad, screws to connect two half-couplinves, has assemblage gap between two half-couplinves.
Further, described water pump spindle is installed the surface and is provided with the semi-ring mounting groove.
Further, described antipad adopts the polyethylene material.
Further, described antipad is annular.
Compare with telescopic rigid coupling, the utlity model has following characteristics: 1. installation and removal are convenient, do not affect after the dismounting again and install.To the motor shaft requirement on machining accuracy than telescopic rigid coupling require low.3. only need to change coupling if coupling damages, and need not to change water pump spindle, maintenance cost is low.4. good to motor adaptability, different motor producers namely need not to redesign coupling as long as the diameter of axle is identical, and motor shaft need not fitting key.5. water pump spindle and motor shaft coaxality are good after installing, and coaxality can not be subjected to install to be affected.
