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
