Description
Technical field
Thrust bearing axially locking technology is rolled the present invention relates to vertical machine, a kind of vertical machine rolling is related specifically to
Dynamicthrust bearing axial locking mechanism.
Background technology
Prior art vertical machine rolls the axial retaining mechanism of thrust bearing and generally uses stopping step, stop washer and lock
Tight nut is fixed on the rotating shaft.It is contaminated to prevent from rolling thrust bearing, is rolling the both sides difference of thrust bearing
It is provided with internal bearing cover and bearing end cover.During specific installation, stopping step is set on motor rotation axis, thrust bearing will be rolled
Suit on the rotating shaft, is close to stopping step, then covers and load onto stop washer and fastened with locking nut, then, is rolling thrust
The both sides of bearing are respectively mounted upper bearing (metal) inner cap and bearing end cover.However, in motor operation course, load can be rotated to motor
Axle produces a motive force vertically downward, so that drive motor rotor produces the trend moved downward.Now motor turns
There is stronger interaction between son and stator, prevent rotor as rotary shaft is moved downward so that roll thrust axis
Hold and relative motion is produced between rotary shaft, so that stop washer and locking nut bear larger axial force, and stop
Packing ring is set with the rotating shaft, and all axial forces are acted on locking nut., may when this axial force is sufficiently large
The screw thread destroyed in locking nut or/and rotary shaft, makes the failure of locking nut so that rotor loosens or de- with rotary shaft
Fall, so as to trigger accident.Obviously, prior art vertical machine roll the axial retaining mechanism of thrust bearing exist can not bear compared with
Big axial force, may make the failure of locking nut so that rotor loosens or come off with rotary shaft, so as to trigger accident etc.
Problem.
The content of the invention
Larger axle can not be born by being existed for the axial retaining mechanism of solution prior art vertical machine rolling thrust bearing
Xiang Li, may make the failure of locking nut so that rotor loosens or come off with rotary shaft, so that the problems such as triggering accident,
The present invention proposes that a kind of vertical machine rolls the axial retaining mechanism of thrust bearing.Vertical machine of the present invention rolls thrust bearing axial direction
Retaining mechanism includes stopping step, stop washer and locking nut, it is characterised in that in the side roll thrust of spinning locking nut one
Snap ring groove is set on the motor rotation axis at bearing face, and two cross sections are installed on stop for the semicircle locating snap ring of rectangle
In annular groove, the locating ring with interior step is sleeved on machine shaft and locating snap ring is sleeved on inside interior step, in locating ring
Top be set with stop washer, and using locking nut fastening.
The advantageous effects that vertical machine of the present invention rolls the axial retaining mechanism of thrust bearing are can to effectively improve rolling
The axial carrying capacity of dynamicthrust bearing locking mechanism, it is ensured that rotor and rotary shaft under larger responsive to axial force not yet
Loosening can be produced or come off, also, it is simple in construction, cost is relatively low, dependable performance.
Brief description of the drawings
Accompanying drawing 1 is the schematic diagram that prior art vertical machine rolls the axial retaining mechanism of thrust bearing；
Accompanying drawing 2 is the schematic diagram that vertical machine of the present invention rolls the axial retaining mechanism of thrust bearing.
Vertical machine of the present invention is rolled with specific embodiment below in conjunction with the accompanying drawings the axial retaining mechanism of thrust bearing make into
The explanation of one step.
Embodiment
Accompanying drawing 1 is rolled for prior art vertical machine in the schematic diagram of the axial retaining mechanism of thrust bearing, figure, and 1 is rolling
Thrust bearing, 2 be internal bearing cover, and 3 be bearing end cover, and 4 be stop washer, and 5 be locking nut, and 6 be rotary shaft.As seen from the figure,
Prior art vertical machine rolls the axial retaining mechanism of thrust bearing and generally uses stopping step, stop washer 4 and locking nut 5
It is fixed in rotary shaft 6.During specific installation, stopping step is set on motor rotation axis 6, thrust axis bearing sleeve 1 will be rolled
In rotary shaft 6 and it is close to stopping step, then covers and load onto stop washer 4 and fastened with locking nut 5, then, is pushed away in rolling
The both sides of power bearing are respectively mounted upper bearing (metal) inner cap 2 and bearing end cover 3.However, in motor operation course, load can be to motor
Rotary shaft produces a motive force vertically downward, so that drive motor rotor produces the trend moved downward.It is now electric
There is stronger interaction between machine rotor and stator, prevent rotor as rotary shaft is moved downward so that rolling is pushed away
Relative motion is produced between power bearing and rotary shaft, so that stop washer and locking nut bear larger axial force, and
Stop washer is set with the rotating shaft, and all axial forces are acted on locking nut.When this axial force is sufficiently large,
The screw thread that may be destroyed in locking nut or/and rotary shaft, makes the failure of locking nut so that rotor loosens with rotary shaft
Or come off, so as to trigger accident.Obviously, prior art vertical machine rolls the axial retaining mechanism of thrust bearing and exists and can not hold
By larger axial force, the failure of locking nut may be made so that rotor loosens or come off with rotary shaft, so as to trigger thing
Therefore the problems such as.
Accompanying drawing 2 is rolled for vertical machine of the present invention in the schematic diagram of the axial retaining mechanism of thrust bearing, figure, and 1 pushes away for rolling
Power bearing, 2 be internal bearing cover, and 3 be bearing end cover, and 4 be stop washer, and 5 be locking nut, and 6 be rotary shaft, and 7 be locating snap ring, 8
For locating ring.As seen from the figure, vertical machine of the present invention, which rolls the axial retaining mechanism of thrust bearing, includes stopping step, stop washer
4 and locking nut 5, it is characterised in that set on the motor rotation axis of the side roll thrust bearing end of spinning locking nut one
Snap ring groove is put, two cross sections are installed in snap ring groove for the semicircle locating snap ring 7 of rectangle, the locating ring with interior step
8 are sleeved on machine shaft and locating snap ring 7 are sleeved on inside interior step, and stop washer 4 is set with the top of locating ring 8,
And fastened using locking nut 5.Vertical machine of the present invention rolls the axial retaining mechanism of thrust bearing and bears axial direction using locating snap ring
Power, because locating snap ring is the semicircle that two cross sections are rectangle, can be caught in the stop in rotary shaft from the radial direction of rotary shaft
In annular groove, an annulus is formed.And step is sleeved on the outside of locating snap ring in locating ring, locating snap ring formation one on the one hand can be kept
Individual complete annulus, on the other hand can ensure two semicircles of locating snap ring will not move radially outward.Because locating snap ring is transversal
Face is rectangle and is installed in snap ring groove, the axial carrying capacity of retaining mechanism has been significantly increased, even in axial force
It is also impossible to destroy locating snap ring when sufficiently large, so as to not ensure rotor and rotary shaft under larger responsive to axial force also not
Loosening can be produced or come off, and then trigger accident.Vertical machine of the present invention rolls the axial retaining mechanism locking nut of thrust bearing
Main function be that locating ring is fastened on above locating snap ring, the interior step of locating ring is tightly entangled locating snap ring, it is ensured that its
Retaining mechanism under external force, will not fail.
Obviously, the advantageous effects that vertical machine of the present invention rolls the axial retaining mechanism of thrust bearing are effectively to carry
Height rolls the axial carrying capacity of thrust bearing retaining mechanism, it is ensured that rotor and rotary shaft are under larger responsive to axial force
Also loosening will not be produced or come off, also, it is simple in construction, cost is relatively low, dependable performance.
