Abstract
The utility model discloses a stable form motor cover includes the lid, shaft hole on the lid, bearing frame and spacing seat three set up and all are located the center of lid with one heart, the shaft hole pierces through the lid, the periphery that the bearing frame was located in the inner chamber and the spacing seat of apron in bearing frame and spacing seat, be provided with the height that the bearing and the bearing height are greater than the bearing frame in the bearing frame, be provided with the elasticity locating part in the spacing seat, the inside and outside both sides of elasticity locating part are hugged closely and are exposed in the bearing wall of bearing frame and spacing seat in order to carry out radical location to the bearing at the bearing. The new skew in order to avoid the bearing of this practicality by this adopts the bearing frame to carry out fixed mounting to the bearing, when considering wearing and tearing that the bearing frame probably appears or tolerance problem again, go on the bearing through the elasticity locating part further spacing, and the elasticity locating part since can elastic deformation consequently can the compensating shaft bearing wearing and tearing or the bearing radical location failure that the tolerance led to the fact, and then result in motor shaft diameter runout problem.
Description
Technical field
The utility model is related to machine field, more particularly to a kind of stable type motor cover.
Background technology
Conventional motors end cap, is mostly flat-disc formula end cover structure, its solid consuming material, and mechanical strength is not high and presses
During casting, internal structure is loose, and area is less and causes heat-transfer effect poor, also there is certain potential safety hazard.Needs are important to note that
, traditional forward and backward motor cover is to be made using steel material and need to be heat-treated, and operation is also more;Should
The forward and backward motor cover shape of class usually outside is larger and the inside is less, when outside is screwed in above motor casing, inner
Space is produced between the less part meeting in side and motor, the concentricity issues and bearing for eventually resulting in motor shaft are easily ground with cover
Damage.And the axiality between motor shaft and axis hole, accuracy are poor, therefore can there are problems that.
So, how to design that a kind of axiality is high, accuracy is good and will not circular runout stable type motor cover just into
For the problem that the field is explored for a long time.
Utility model content
The technical problem that the utility model is solved is to overcome Shortcomings in above-mentioned prior art and provide a kind of stable
Type motor cover, it is characterised in that including lid, the lid are provided with axis hole, bearing block and limit base, the axis hole, axle
Bearing and limit base three are arranged concentrically and are respectively positioned on the center of lid, and the axis hole penetrates lid, bearing block and spacing seat
The periphery of bearing block is located in the inner chamber and limit base of cover plate, bearing is provided with the bearing block and bearing height is more than bearing
The height of seat, is provided with elastic spacing one, is close to bearing and exposes inside and outside the elastic spacing one in the limit base
In the bearing wall and limit base of bearing block carrying out radial positioning to bearing.
The utility model can also be further perfect by following technical measures:
Used as further improving, the elastic spacing one is rubber ring.
Used as further improving, the lid is circle, and the inner surface of the outer peripheral edge of lid is the conical surface.
As further improving, the multiple fixed seats for penetrating lid surfaces externally and internally on the lid, are provided with.
As further improving, multiple louvres for penetrating lid surfaces externally and internally between fixed seat, are provided with.
Used as further improving, the bearing block and limit base are formed in one.
Used as further improving, the lid is made up of stainless steel.
Used as further improving, the elastic spacing one detachable connection is on limit base.
As a result of above technical measures, the utility model at least has following Advantageous Effects:
1st, the utility model is felt relieved to motor shaft by bearing, so as to solve in prior art motor shaft with
Axiality, accuracy between axis hole is poor, therefore can there are problems that.In order to avoid the skew of bearing, adopt
Bearing block is fixed installation to bearing, it is also contemplated that when the abrasion that is likely to occur of bearing block or tolerance issues, by elasticity limit
Position part carries out further spacing to bearing, and elastic spacing one is due to abrasion that is resiliently flexible therefore can compensating bearing block
Or the bearing radial positioning failure that tolerance is caused, and then cause motor shaft circular runout problem.And elastic spacing one is detachable
Connection, can be changed when damaging in time.
2nd, the inner surface of the outer peripheral edge by lid of the present utility model is the conical surface and can be with the conical surface of casing operationally
Closely connection is conducive to improving stability when motor is installed.And the simple structure of whole stable type motor cover, it is easy to processing, into
This is relatively low, and operation is less, long service life, steady quality.
3rd, the utility model disperses the big calorimetric produced when motor internal works by arranging louvre
Amount, the cooling for being more beneficial for motor and the life-span for extending motor.And setting heat sink strip then can be significantly on the outer surface of lid
Increase the contact area of lid and the external world, so as to the rapid radiating of motor.
Description of the drawings
Fig. 1 is the stereogram of stable type motor cover of the present utility model.
Specific embodiment
Further details of elaboration is done to the utility model below in conjunction with accompanying drawing.
Of the present utility model a kind of stable type motor cover as shown in accompanying drawing 1 includes lid 1, and the lid 1 is provided with
Axis hole 11, bearing block 12 and limit base 13, the axis hole 11, bearing block 12 and 13 three of limit base are arranged concentrically and are respectively positioned on lid
The center of body 1.The bearing block 12 and limit base 13 are formed in one.The axis hole 11 penetrates lid 1, bearing block 12 and limit
Position seat 13 be located at cover plate 1 inner chamber and limit base 13 located at bearing block 12 periphery, be provided with the bearing block 12 bearing 2 and
2 height of bearing is provided with elastic spacing one 3 more than the height of bearing block 12 in the limit base 13, the elastic spacing one is
Rubber ring.Be close to inside and outside the elastic spacing one 3 bearing 2 expose to the bearing wall and limit base 13 of bearing block 12 with
Radial positioning is carried out to bearing 2.Thereby the utility model is felt relieved to motor shaft by bearing 2, existing so as to solve
Axiality, accuracy in technology between motor shaft and axis hole 11 is poor, therefore can there are problems that.In order to avoid
The skew of bearing 2, is fixed installation using bearing block 12 to bearing 2, it is also contemplated that the abrasion that is likely to occur of bearing block 12 or
During tolerance issues, bearing 2 is carried out by elastic spacing one 3 further spacing, and elastic spacing 3 is due to resiliently flexible
Therefore the bearing radial positioning failure that the abrasion of bearing block 12 or tolerance are caused can be compensated, and then causes motor shaft circular runout
Problem.And 3 detachable connection of elastic spacing one, can change in time when damaging.
