Abstract
The invention relates to a coupling for connecting a water pump shaft and a motor shaft. The coupling for connecting the water pump shaft and the motor shaft is formed by the connection of two half coupling bodes, a half slot is formed in the center of the connection surface of the two half coupling bodies along the axis direction, an intermediate-shaft arc slot is arranged at the middle section of the half slot, the semicircle diameter of the intermediate-shaft arc slot is greater than the semicircle diameter of the half slot, and an arc slot hole connecting the water pump shaft and the motor shaft is formed in the axis direction after the two half coupling bodies are connected. Opponent concave-type shoulders are correspondingly arranged at two sides of the arc slot in the upper end and the lower end of the two half coupling bodies respectively, fixing screw holes or through holes which are perpendicular to the connection surface of the coupling bodies are formed in the concave-type shoulders, and bolts or screws which are capable of connecting two half coupling bodies and clamping the water pump shaft and the motor shaft are arranged inside the concave-type shoulders. The coupling for connecting the water pump shaft and the motor shaft has the advantages that the structure is simple, the installation and the utilization are convenient, the concentricity is good, the clamping force is strong, and the operating noise is low and the like.
Description
Technical field
What the present invention relates to is a kind of coupling connecting water pump spindle and motor shaft, belongs to pump coupler technical field.
Background technique
In prior art, the running of water pump spindle realizes by connecting motor shaft, and the working efficiency height based on water pump is closely related with the transmission of power of motor, and therefore connecting water pump spindle and the linking mechanism of motor shaft, whether to be connected fastness good, good concentricity, operating steadily etc. plays an important role; Because existing conventional coupling is not too applicable to the transmission of power of water pump, is therefore badly in need of a kind of good concentricity, easy installation and removal, steps up the pump coupler that dynamics is strong.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art existence, and provide a kind of structure simple, easy to install, good concentricity, steps up dynamics by force, runs the coupling of the little connection water pump spindle of noise and motor shaft.
The object of the invention is to have come by following technical solution, a kind of coupling connecting water pump spindle and motor shaft, it connects primarily of two halves coupling body and forms, on the junction surface of described coupling body, vertically center offer half slot, wherein the intermediate section of half slot is provided with half circular diameter and is greater than the jack shaft of half slot half circular diameter to arc groove, and be axially formed with arc groove hole water pump spindle and motor shaft linked together after two halves coupling body is connected.
The described upper and lower two end part of two halves coupling body, be positioned at the half slot both sides corresponding notch type shoulders be provided with in opposite directions respectively, described shoulders offers the fixing threaded hole perpendicular to coupling body abutted surface or through hole, be wherein configured with and two halves coupling body can be connected together and bolt together with water pump spindle is interposed in motor shaft or screw.
Described coupling body be the more than half cylinder of epimere and hypomere smaller part cylinder one form, and the more than half cylinder of epimere be respectively provided with a radial semicircle bulge loop up and down; The notch type shoulders of described coupling body upper end portion is arranged on the big semicircle post jamb face between semicircle bulge loop.
It is simple that the present invention has structure, easy to install, good concentricity, steps up the features such as dynamics is strong, and operation noise is little.
