Abstract
A kind of device 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; It is simple that it has structure, easy to install, good concentricity, steps up the features such as dynamics is strong, and operation noise is little.
Description
Technical field
The utility model relates to a kind of device connecting water pump spindle and motor shaft, belong to pump device technique 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 equipment 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 device that dynamics is strong.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art existence, and provides a kind of structure simple, and easy to install, good concentricity, steps up dynamics by force, runs the device of the little connection water pump spindle of noise and motor shaft.
The purpose of this utility model has been come by following technical solution, a kind of device 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 utility model has structure, easy to install, good concentricity, steps up the features such as dynamics is strong, and operation noise is little.
