Embodiment
The pump that the utility model is provided is made in detail of the embodiment of elastic column axis coupling below in conjunction with the accompanying drawings Describe in detail bright.
Referring to Fig. 2, the utility model pump includes pump shaft coupling 20 and motor coupler 21 with elastic column axis coupling. A lengthened coupling 22 is provided between the 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 with the motor coupler 21 axially through at least two groups bolts and nut assembly 23 to be 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 bolt 230 that connects of the motor coupler 21 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 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, this boss and pit are just seam on workpiece.
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 being connected in the side of pump shaft coupling 20 with the pin 240, setting Spring washer 242 in the inner side of the nut 241, it is enclosed on the outer surface of pin 240 and joins positioned at lengthened coupling 22 with 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 phase interworking at taper, 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, can also be selected according to use environment Its quantity, the utility model is to this without limiting.
The pump shaft coupling 20 passes through the lengthened coupling 22 and the elastic pin bank with the motor coupler 22 Part 24 transmits moment of torsion.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 long shaft coupling 22 and the elastic ring 243 being fixed on pin 240 contact to transmit moment of torsion.
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.The length of the lengthened coupling 22 is more than the length of pump shaft coupling 21;For During multistage pump, the length of the lengthened coupling 22 is more than the length of centrifugal multistage pump multiple centrifugal pump bearing body part;For centrifugal pump of single stage type When, the length of the lengthened coupling 22 is more than the dimensions length needed for the part outside the pump housing takes out, in order to retract part dimension Repair.Further, more than the material selection trade mark QT500-7 of the pump shaft coupling, motor coupler and lengthened coupling spheroidal graphite 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, finally the parts such as parts of bearings or the sealing changed will be needed to be taken out from the gap of lengthened coupling 22.This practicality New advantage is that transmission moment of torsion is big, damping, buffering, and without lubrication, convenient disassembly need not dismantle connecting line during maintenance water pump With move motor, it is time saving and energy saving.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art Art personnel, on the premise of the utility model principle is not departed from, can also make some improvements and modifications, these improvements and modifications Also it should be regarded as protection domain of the present utility model.
