Embodiment
Core of the present invention provides a kind of bearing axial securing means for impeller, in the axial restraint bearing, can store lubricating grease.
In order to make those skilled in the art person understand better the present invention program, below in conjunction with the accompanying drawing in the embodiment of the invention, the technological scheme in the embodiment of the invention is clearly and completely described.
Please refer to Fig. 1-Fig. 7, bearing axial securing means for impeller provided by the present invention comprises that lock washer 15 is connected the grease regulator 12 that is connected with being connected with the rotating shaft 11 that bearing 14 is installed with lock washer.The inner ring of lock washer 15 is provided with stop ear 21, and grease regulator 12 forms grease receiving cavity 13 with the end face of bearing 14, and grease regulator 12 screws togather with rotating shaft 11.
With respect to prior art, the invention has the beneficial effects as follows: lock washer 15 is set can axial restraint grease regulator 12, prevents that grease regulator 12 is loosening and produce axial displacement, and the removing and installing conveniently of lock washer 15; Grease regulator 12 is set, can in rigid bearing, stores lubricating grease, lubricating bearings 14, the working life of improving bearing 14.
The height of the diapire of grease regulator 12 can be a shade below the height of the inner ring of bearing 14, to reduce the waste of lubricating grease.The tapped hole of the diapire that lock washer 15 can be connected with the grease regulator by screw is connected with grease regulator 12, and is time saving and energy saving.
Certainly, grease regulator 12 also can comprise connecting plate and dividing plate, and lock washer 15 is connected with connecting plate by screw; The end face of the diapire of dividing plate and grease regulator 12 and bearing 14 forms grease receiving cavity 13.Perhaps grease regulator 12 is made as other shapes, this paper repeats no more.
The inner ring of lock washer 15 is provided with stop ear 21, after grease regulator 12 installs, stop ear 21 is arranged in the groove of rotating shaft 11, is used for axial restraint grease regulator 12, prevents from that grease regulator 12 from use producing to move axially; And lock washer 15 removes and installs conveniently, and is time saving and energy saving.
A stop ear 21 can be provided with at the inner ring of lock washer 15, also two stop ears 21 can be arranged with at the inner ring of lock washer 15.It is simple in structure, easy for installation that a stop ear 21 is set, convenient fixedly grease regulator 12; Arrange two stop ears 21 can be better fixing grease regulator 12, prevent from that grease regulator 12 from producing to move axially.
Certainly, the stop ear 21 more than three or three can be set also, perhaps the asymmetric stop ear 21 that arranges does not repeat them here.
The shape of stop ear 21 can be irregularly shaped for rectangular or other.Preferentially select the rectangular that is shaped as of stop ear 21 herein, and preferentially select the symmetrical center line of stop ear 21 to overlap with the diameter of lock washer 15.
So arrange, 21 processing of stop ear are easy for installation, and can conveniently process the groove in the rotating shaft 11, and the axial restraint bearing 14 better.
Can waist-shaped hole 22 be set at lock washer 15, at grease regulator 12 tapped hole be set, be connected screw with tapped hole and be connected with grease regulator 12 by being arranged on waist-shaped hole 22 to make things convenient for lock washer 15.Waist-shaped hole 22 is easy to process, and screw conveniently is set.The length of waist-shaped hole and width can be set according to the size of lock washer and the size of screw.
Certainly, also hole of circle or other shapes etc. can be set at lock washer 15.
In a kind of embodiment, at lock washer 15 six waist-shaped holes 22 are set, along the circumferential direction evenly be provided with six tapped holes at connecting plate.The angle that the line in the center of six waist-shaped holes 22 and the center of circle of lock washer 15 and the center of a stop ear 21 become with the line in the center of circle of lock washer 15 is followed successively by 50 °, 70 °, 90 °, 200 °, 220 ° and 240 ° along clockwise direction, can certainly be followed successively by in the counterclockwise direction 50 °, 70 °, 90 °, 200 °, 220 ° and 240 °.
So arrange, no matter how how grease regulator 12 arranges, and it is relative with tapped hole to ensure all the time a waist-shaped hole 22, connects lock washer 15 and grease regulator 12 with convenient with screw; And convenient processing and manufacture, time saving and energy saving.
In another kind of embodiment, the center that 22, ten two waist-shaped holes 22 of 12 waist-shaped holes are set at lock washer 15 is followed successively by 50 °, 70 °, 90 °, 120 °, 140 °, 160 °, 200 °, 220 °, 240 °, 270 °, 290 ° and 310 ° with the angle that the center of the line in the center of circle of lock washer 15 and one of them stop ear 21 becomes with the line in the center of circle of lock washer 15.
Certainly, because the error of manufacturing, angle may definitely not be above-mentioned angle.
So arrange, no matter how how grease regulator 12 arranges, and it is relative with tapped hole to ensure all the time two waist-shaped holes 22, so that screw conveniently to be set.Two screws are set better connect lock washer 15 and grease regulator 12.
Certainly, the tapped hole of other quantity also can be set at grease regulator 12, or tapped hole is arranged on the grease regulator 12 with other arrangement modes.The hole of other quantity etc. also can be set on the lock washer 15, and this paper repeats no more.
More than bearing axial securing means for impeller provided by the present invention is described in detail.Used specific case herein principle of the present invention and mode of execution are set forth, above embodiment's explanation just is used for helping to understand method of the present invention and core concept thereof.Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also carry out some improvement and modification to the present invention, these improvement and modification also fall in the protection domain of claim of the present invention.
