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

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.
