Abstract
A kind of two-way spline thrust bearing disclosed by the invention, including armature spindle, thrust bearing, carborundum axle sleeve, the carborundum axle sleeve includes carborundum outer shaft and carborundum internal axle sleeve, the carborundum internal axle sleeve axle is located in the endoporus of the carborundum outer shaft, coupled between the inner ring of the thrust bearing and the armature spindle using spline form, also coupled between the inner ring of the thrust bearing and the carborundum internal axle sleeve using spline form.Two-way spline connection structure is used between the inner ring and armature spindle and carborundum internal axle sleeve of the thrust bearing of the present invention, when canned motor pump in the running, armature spindle passes to moment of torsion by spline structure the inner ring of thrust bearing, carborundum internal axle sleeve is passed to by spline structure by the inner ring of thrust bearing again, is so achieved that the function of stainless steel armature spindle and carborundum axle sleeve run-in synchronism.
Description
Technical field
The present invention relates to shielding pump technical field, more particularly to canned motor pump inertial thrust bearing arrangement, more particularly to one kind
Two-way spline thrust bearing.
Background technology
Canned motor pump uses sliding bearing structure, and common sliding bearing structure is that carborundum axle sleeve forms to SiC bearing
Friction pair.In order that carborundum axle sleeve and stainless steel shaft run-in synchronism, must will process two planes on axle, and will carbonization
Silicon axle sleeve is fixed on given shape stainless steel substrates, is then enclosed on axle, makes itself and axle run-in synchronism.So not only processing is multiple
It is miscellaneous, and thrust bearing is played a part of axial limiting.
The content of the invention
The technical problems to be solved by the invention are to be directed to because carborundum fragility is high, not easy processing, it is difficult to make its with
The problem of stainless steel shaft run-in synchronism and a kind of two-way spline thrust bearing is provided.The two-way spline thrust bearing leads to
The structure for changing thrust bearing is crossed, it is played a part of axial limiting, moreover it is possible to realize carborundum axle sleeve and stainless steel
The function of axle run-in synchronism.
The technical problems to be solved by the invention can be achieved through the following technical solutions：
A kind of two-way spline thrust bearing, including armature spindle, thrust bearing, carborundum axle sleeve, the carborundum axle
Set includes carborundum outer shaft and carborundum internal axle sleeve, and the carborundum outer shaft is fixed on canned motor pump end cap, the carbonization
Silicon internal axle sleeve axle is located in the endoporus of the carborundum outer shaft, it is characterised in that the inner ring of the thrust bearing and described turn
Coupled between sub- axle using spline form, spline shape is also used between the inner ring of the thrust bearing and the carborundum internal axle sleeve
Formula couples.
Using two-way spline connection knot between the inner ring and armature spindle and carborundum internal axle sleeve of the thrust bearing of the present invention
Structure, when canned motor pump in the running, armature spindle passes to moment of torsion by spline structure the inner ring of thrust bearing, then by thrust bearing
Inner ring carborundum internal axle sleeve is passed to by spline structure, be so achieved that stainless steel armature spindle is synchronous with carborundum axle sleeve
The function of operating.
The thrust bearing of the present invention can not only bear axial force, additionally it is possible to transmit moment of torsion so that the service life of canned motor pump
It is significantly improved.
Brief description of the drawings
Fig. 1 is an application example schematic diagram of the two-way spline thrust bearing of the present invention.
Embodiment
Referring to Fig. 1, a kind of shielding pump group part for the two-way spline thrust bearing for applying the present invention is given in figure, its
Including housing 10, upper end cap assemblies 1, step component 8, rotor 11, stainless steel armature spindle 5, up-thrust bearing 4, under push away
Power bearing 6, upper carborundum axle sleeve 3, lower carborundum axle sleeve 7, rotor 11 are fixed on stainless steel armature spindle 5 and are arranged on housing
In 10, upper and lower carborundum axle sleeve 3,7 includes carborundum outer shaft 3a, 7a and carborundum internal axle sleeve 3b, 7b, upper carborundum outer shaft
Set 3a is fixed on the upper end cap assemblies 1 of housing, and upper carborundum internal axle sleeve 3b axles are located at carborundum outer shaft 3a endoporus
In, lower carborundum internal axle sleeve 7b is fixed on step component 8, and lower carborundum outer shaft 7a axles are located at lower carborundum internal axle sleeve
In 7b endoporus.
It is characteristic of the invention that using flower between the inner ring and the upper and lower end of stainless steel armature spindle 5 of upper and lower thrust bearing 4,6
Key-shaped formula couples, and the inner ring of upper and lower thrust bearing 4,6 still uses spline form between upper and lower carborundum outer shaft 3a, 7a
Connection.
Impeller 9 is fixed with the lower end of stainless steel armature spindle 5.
