Further, the lengthened coupling is diametrically positioned with the motor coupler by seam.
Further, the lengthened coupling passes through at least two groups bolts and nut group in the axial direction with the motor coupler Part is fixedly connected.
Further, spring washer is provided with the inside of nut.
Further, each spring column pin component include pin, the nut that is connected with the pin in pump shaft coupling side, It is arranged on the spring washer on the inside of the nut, is enclosed within the pin outer surface and between lengthened coupling and pump shaft coupling Elastic ring and the back-up ring being arranged in the column pin hole of lengthened coupling.
Further, pin be located at pump shaft coupling side outer surface be taper, it is corresponding, at this of pump shaft coupling in table Face is taper.
Further, the quantity of the spring column pin component is 4 ~ 12.
Further, the pump shaft coupling and the motor coupler are equipped with screw at its keyway, for installing tightening Screw check.
Further, length of the length of the lengthened coupling more than pump shaft coupling;During for multistage pump, the lengthening connection Length of the length of axle device more than centrifugal multistage pump multiple centrifugal pump bearing body part;During for centrifugal pump of single stage type, the length of the lengthened coupling Degree takes out required dimensions length more than the part outside the pump housing.
Further, more than the material selection trade mark QT500-7 of the pump shaft coupling, motor coupler and lengthened coupling One kind in spheroidal graphite cast-iron, cast steel, forged steel.
It is an advantage of the current invention that transmitting torque is big, and damping, buffering, without lubrication, convenient disassembly need not during maintenance water pump Dismantle connecting line and move motor, it is time saving and energy saving, operating efficiency is greatly improved, save maintenance cost.

Specific embodiment
The specific embodiment of the pump elastic column axis coupling for providing the present invention below in conjunction with the accompanying drawings is done specifically It is bright.
Referring to Fig. 2, pump of the present invention includes pump shaft coupling 20 and motor coupler 21 with elastic column axis coupling.Described A lengthened coupling 22 is provided between pump shaft coupling 20 and the motor coupler 21.
One end of the lengthened coupling 22 is connected with the motor coupler 21.In this embodiment, it is described One end of lengthened coupling 22 is fixed axially through at least two groups bolts and nut assembly 23 with the motor coupler 21 and is connected Connect, for example, 4 ~ 12 groups of two groups of bolts and nut assembly.Each group of bolt and nut assembly 23 include and the lengthened coupling 22 One end and the connection of the motor coupler 21 bolt 230 and be arranged on the side of motor coupler 21 and coordinate with the bolt 230 Fixed nut 231, spring washer 232 is provided with the inner side of the nut 231.The lengthened coupling 22 joins with the motor Axle device 21 is diametrically positioned by seam, and seam orientates existing conventional method as, and wherein seam is meant that, for ease of two Individual workpiece positioning, processes boss or pit on workpiece, and this boss and pit are just seam.
The other end of the lengthened coupling 22 is connected by least two spring column pin components 24 with pump shaft coupling 20.Often Spring column pin component 24 described in one includes pin 240, the nut 241, the setting that are connected with the pin 240 in the side of pump shaft coupling 20 Spring washer 242 in the inner side of the nut 241, it is enclosed within the outer surface of the pin 240 and joins positioned at lengthened coupling 22 and pump Elastic ring 243 and the back-up ring 244 being arranged in the column pin hole 220 of lengthened coupling 22 between axle device 20.Pin 240 joins positioned at pump The outer surface of the side of axle device 20 is taper, corresponding, and inner surface is taper, taper phase interworking at two at this of pump shaft coupling 20 Close, fixed effect can be further functioned as.The quantity of the spring column pin component is 4 ~ 12, also dependent on use environment selection Its quantity, the present invention is not defined to this.
The pump shaft coupling 20 is with the motor coupler 22 by the lengthened coupling 22 and the elastic pin bank The transmitting torque of part 24.More specifically, pump shaft coupling 20 and motor coupler 21 are by being fixed on adding on motor coupler 21 The column pin hole 220 of shaft coupling long 22 and the contact of elastic ring 243 being fixed on pin 240 carry out transmitting torque.
Further, the pump shaft coupling 20 and the motor coupler 21 are equipped with screw at its keyway 201 and 211 202 and 212, it is locking for installing holding screw.Length of the length of the lengthened coupling 22 more than pump shaft coupling 21;For During multistage pump, the length of the length more than centrifugal multistage pump multiple centrifugal pump bearing body part of the lengthened coupling 22;For centrifugal pump of single stage type When, the length of the lengthened coupling 22 takes out required dimensions length more than the part outside the pump housing, in order to retract part dimension Repair.Further, the spheroidal graphite of more than the material selection trade mark QT500-7 of the pump shaft coupling, motor coupler and lengthened coupling One kind in cast iron, cast steel, forged steel.
Need repairing pump when, first turn on nut 241 successively and remove spring column pin component 24, next step is by nut 231, bullet Spring packing ring 232 and bolt 230 are dismantled, and lengthened coupling 22 is removed, and further tear pump shaft coupling 21 or motor coupler 21 open Remove, will finally need the parts such as parts of bearings or the sealing changed to be taken out from the gap of lengthened coupling 22.The present invention Advantage be transmitting torque big, damping, buffering, without lubrication, convenient disassembly need not dismantle connecting line and move during maintenance water pump Dynamic motor is time saving and energy saving.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art Member, under the premise without departing from the principles of the invention, can also make some improvements and modifications, and these improvements and modifications also should be regarded as Protection scope of the present invention.
