The fixing device is designed by technicians according to problems generated in actual use of the bearing, is simple in structure and convenient for use, can be widely applied to bearings with different types, and solves the problem of axial movement of traditional bearings during working.
Description
Technical field
The invention belongs to mechanical manufacturing field, particularly to a kind of bearing axial securing means for impeller.
Background technology
Bearing is a kind of important spare part in contemporary plant equipment.Its major function is supporting machinery rotary body, reduces
Coefficient of friction in its motor process, and ensure its rotating accuracy.The use of bearing is very universal, in order in the inner side installing thing
Face fixedly mounts bearing, prevents bearing from deviating from from both sides, often designs some complicated location structures in the both sides installing thing,
So that the structure of product becomes complicated, it is not easy to install, the ball in bearing weares and teares sternly because of the effect of frictional force simultaneously
Weight.
Content of the invention
It is an object of the invention to provide a kind of structure is simple, axial float can be reduced in use and will not take off outward
Bearing fixing device.
A kind of bearing axial securing means for impeller, this fixing device include bearing, fixing body, upper installing hole, handling hole, sleeve,
Spring, lower installing hole；Described bearing outside surface is provided with lower installing hole；The inner surface of fixing body is provided with upper installing hole；Fixing body set
It is contained in the outer surface of bearing；The cylindrical structure of described sleeve, is sleeved on one end of spring；Spring is helical spring, with set
Cylinder endoporus matches；It is provided with handling hole in the outer surface relevant position of described fixing body, handling hole is connected with upper installing hole；Described
Axial height 1～the 2mm less than the length of lower installing hole of sleeve；The length bigger than the length of lower installing hole 3 of spring naturalness
～5mm；
When needing bearing is installed to inside fixing body, first sleeve and spring are snapped in lower mounting groove, and to sleeve from axle
To force, spring is made to be compressed, when bearing is in fixing body medial movement, and when upper installing hole is overlapped with lower installing hole, sleeve
Reset under the effect of spring power, and snap in upper installing hole, thus sleeve is stuck in upper installing hole and lower installing hole shape simultaneously
In the mounting groove becoming, prevent bearing from moving axially.
When needing to disassemble bearing from fixing body, insert inserted link in handling hole, compacting sleeve makes spring pressure
Contracting, until sleeve departs from from upper installing hole, completely into lower installing hole, more axially promotes bearing by external force, bearing is with regard to energy
Enough separate from fixing body.
Further, 1～4 fixing device can be arranged on same bearing.
Further, 3 fixing devices can be arranged on same bearing.
The present invention be technical staff according to the bearing problem producing when actually used and a kind of fixing device designing, no
Only structure is simple, and easy to use, can widely use different types of bearing, solve traditional bearing and operationally produce
The problem of axial float.
Brief description
Fig. 1 is the structural representation of bearing axial securing means for impeller of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings the present invention is described in detail.
As shown in figure 1, a kind of bearing axial securing means for impeller, this fixing device include bearing 1, fixing body 2, upper installing hole 3,
Handling hole 4, sleeve 5, spring 6, lower installing hole 7.Bearing 1 outer surface is provided with lower installing hole 7；The inner surface of fixing body 2 is provided with
Installing hole 3；Fixing body 2 is sleeved on the outer surface of bearing 1.The cylindrical structure of sleeve 5, is sleeved on one end of spring 6.Spring 6
For helical spring, match with sleeve 5 endoporus.Axial height 1～the 2mm less than the length of lower installing hole 7 of sleeve 5.Spring 6
Length 3～the 5mm bigger than the length of lower installing hole 7 of naturalness.
During use, when bearing 1 is installed to before fixing body 2 inner side, first sleeve 5 and spring 6 are snapped in lower mounting groove 7,
And to sleeve 5 from axial force distribution, so that spring 6 is compressed, when bearing 1 is in fixing body 2 medial movement, and upper installing hole 3 with
When installing hole 7 overlaps, sleeve 5 resets under spring 6 resilient force, and snaps in upper installing hole 3, thus sleeve 5 blocks simultaneously
In the mounting groove that upper installing hole 3 is formed with lower installing hole 7, prevent bearing 1 from moving axially.
In order to bearing 1 is disassembled from fixing body 2, it is provided with handling in the outer surface relevant position of fixing body 2
Hole 4.Handling hole 4 is connected with upper installing hole 3, when needing to disassemble bearing 1 from fixing body 2, inserts in handling hole 4
Enter inserted link, compacting sleeve 5 makes spring 6 compress, until sleeve 5 departs from from upper installing hole 3, completely into lower installing hole 3, then leads to
Cross external force and axially promote bearing 1, bearing 1 just can be separated from fixing body 2.
Fixing device of the present invention can arrange 1～4 as needed on same bearing, is to correspond to two-by-two to set under normal circumstances
Put.Using effect when uniformly arranging 3 fixing devices on bearing is best.
The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto,
Any those familiar with the art the invention discloses technical scope in, technology according to the present invention scheme and its
Inventive concept equivalent or change in addition, all should be included within the scope of the present invention.
