Abstract
Disclosed in this utility model, a kind of novel combination type electric motor end cap, relates to technical field of motors.Including end cover body 1；Also including bearing fit ring 3, described bearing fit ring 3 is embedded in the interior stepped hole of the bearing chamber 2 in the middle of end cover body 1.Have and can improve the stability of motor, the vibration improving motor rotation and noise, increase electrical machinery life and the feature such as easily manufactured, be suitable for supporting the use with various motors.
Description
Technical field
This utility model relates to technical field of motors, particularly a kind of novel combination type electric motor end cap.
Background technology
In prior art, large-sized motor is such as the series such as 57,90,110, high with moment, determine rotation speed operation, essence
The excellent properties such as degree is high, noise is low, are widely used in the fields such as Industry Control.At present, conventional motor end cap is mostly
It is by ADC12 material one-step die casting, it may be assumed that being all ADC12 including electric motor end cap bearing chamber, this material is at long-term height
Load running is easily worn and torn, after its abrasion with bearing coordinate misalignment, cause the stability of motor to reduce, the noise of motor,
Vibration and life-span deteriorate the most in various degree, and it is unfavorable to bring to subsequent use.Although, also have the end cap of some motors, at its axle
Hold indoor and install lining additional to improve its wearability, but axially not positioning of institute's then lined, play phenomenon easily occurs.
Chinese patent (number of patent application is 200820085637.5) disclosed " a kind of combination type electric motor end cap ", including band
The end cover body of bearing mounting hole, it is characterised in that in the bearing mounting hole of end cover body, socket arranges bearing sheath.
Another Chinese patent (number of patent application is 201320259443.3) is disclosed " combination type electric motor end cap ", and it includes
Lid, beam barrel and installing hole, beam barrel is positioned at the central authorities of lid, and mounting hole site, in the surrounding of lid, is provided with lining in beam barrel.At lid
The beam barrel female thread of body connects a lining, and the internal diameter of lining can be adjusted as required, or according to different machine shafts
Change corresponding lining, to meet the assembling needs of all size motor.
Also have Chinese patent (number of patent application is 201520696954.0) disclosed " a kind of combination type electric motor end cap ", bag
Including end cap body, end cap body is equipped with bearing mounting hole, in bearing mounting hole, interlocking arranges bearing holder (housing, cover), bearing holder (housing, cover) and end
Lid body is integrated die cast structure.
Summary of the invention
For the deficiency existing for existing product, technical problem to be solved in the utility model is to provide one and can improve
The stability of motor, the vibration improving motor rotation and noise, increase electrical machinery life and easily manufactured electric motor end cap.
For achieving the above object, technical solution adopted in the utility model is a kind of novel combination type motor side of design
Lid: include end cover body 1；Also including bearing fit ring 3, described bearing fit ring 3 is embedded in the bearing chamber 2 in the middle of end cover body 1
Interior stepped hole in.
Described bearing fit ring 3 is circular sleeve, within it with bulge loop 4 at the cylindrical of end.
Described bearing fit ring 3 is to use rustless steel to be made.
Novel combination type electric motor end cap of the present utility model, is to install a bearing fit ring in bearing chamber additional, and at this
Also it is equipped with bulge loop at the cylindrical of the medial end of bearing fit ring, during making, is bearing fit ring that rustless steel is made
Be embedded in behind die casting relevant position with matrix ADC12 material molding in the lump, the electric motor end cap blank after molding and conventional work
Without other difference in skill, its manufacture is more convenient, and cost is without increasing.Simultaneously as at the cylindrical of bearing fit ring medial end
With bulge loop, during molding, this bulge loop is embedded in matrix ADC12 material in the lump, therefore bearing fit ring does not haves axle at bearing chamber
To play phenomenon.Additionally, due to bearing fit ring is to use stainless steel to make, its relatively ADC12 material is harder, more resistant to
Mill, thus, motor works long hours after running and is unlikely to deform, and size is more stable, thus improves the stability of motor, improves
Vibration that motor causes because of abrasion after operating for a long time, the situation such as noise, too increase the life-span of motor.

Fig. 2 is left cross-sectional schematic of the present utility model；
Fig. 3 is schematic top plan view of the present utility model；
Fig. 4 is schematic perspective view of the present utility model.
In figure:
1 is end cover body, and 2 is bearing chamber, and 3 is bearing fit ring, and 4 is bulge loop.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further described.Description below is to use to enumerate
Mode, but protection domain of the present utility model should not be limited to this.
The present embodiment is to be made up of end cover body 1 and bearing fit ring 3.
End cover body 1 is quadrilateral shape body, is provided with bearing chamber 2 in the middle of it, and the centre of this bearing chamber 2 has interior step and leads to
Hole.
Bearing fit ring 3 is to use rustless steel to be made, for circular sleeve, in its one end (that is: by bearing chamber 2
The medial extremity of step through-hole bottom surface) portion cylindrical at bulge loop 4.
During making, it is the relevant position that first bearing fit ring 3 is embedded in die casting, then with matrix ADC12 material
Molding in the lump (end cover body 1), becomes novel combination type electric motor end cap of the present utility model, and the electric motor end cap blank after molding is with often
Without other difference in rule technique.
During use, due at the cylindrical of bearing fit ring 3 medial end with bulge loop 4, and this bulge loop 4 is embedded in the lump
In matrix ADC12 material (that is: end cover body 1), therefore bearing fit ring 3 does not haves axially in the interior step through-hole of bearing chamber 2
Play phenomenon.Simultaneously as bearing fit ring 3 is to use stainless steel to make, its relatively ADC12 material is harder, more resistant to mill,
Thus, motor works long hours after running and is unlikely to deform, and size is more stable.
Novel combination type electric motor end cap of the present utility model, is suitable for supporting the use with various motors.
