Abstract
The utility model discloses a kind of machine shaft support construction, belong to technical field of motors, including shell, shaft, bearing and circlip, the bearing is set in shaft, described shell one end is provided with the lug boss for loading bearing, and one end that the shaft passes through bearing is provided with the position limiting structure for limiting shaft axial float.The utility model is designed reasonably, structure is simple, limits fixation by the way that circlip is arranged in shaft, eliminates the axial float of shaft, play the effect of double ball bearing, reduce motor production cost, and make motor operation quieter, steady.
Description
Technical field
The utility model discloses a kind of machine shaft support construction, belongs to technical field of motors.
Background technique
Now, micro-machine uses in different application fields, such as housed device, hand-operated tools, kitchen
Automate the power source of electric appliance, the actuator in motor vehicle or similar devices.Requirement to such motor is higher and higher,
It will also have preferable running stability and muting function other than needing to have high power.
In order to promote the running stability of motor, often at machine shaft both ends, installation bearing is supported, so that electric
It is more stable, reliable in the machine course of work, reduce motor internal drag；However, not only increasing electricity using the structure of duplex bearing
Machine manufactures material, and production technology is more complicated, increases the cost of motor production, and can produce in two bearing rotation processes
Raw biggish noise, influences the muting function of motor.And in motor operation course, axial play easily occurs for shaft, influences electricity
The stability and ride comfort of machine operation, influence equipment overall operation precision.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide for a kind of machine shaft support knot
Structure, to solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides following technical solution to realize:
A kind of machine shaft support construction, it is characterized in that: including shell, shaft and bearing, the bearing is set in shaft
On, described shell one end is provided with the lug boss for loading bearing, and one end that the shaft passes through bearing is provided with for limiting
The position limiting structure of shaft axial float processed.
As preferred: the bearing is ball bearing.
As preferred: mutually contradicting setting between the position limiting structure and bearing.
As preferred: the position limiting structure is circlip, and the circlip is arranged in shaft.
As preferred: the circlip, which is removably secured, to be mounted in shaft.
The utility model has the beneficial effects that
By the way that position limiting structure is arranged, position limiting structure can be defined shaft, prevent shaft play excessive, so that shaft turns
It is dynamic more stable；When shaft is to enclosure interior play, position limiting structure and bearing are bonded to each other compression, and position limiting structure is carried on axis
On the inner ring held, continues the even running for keeping shaft, play the effect of double ball bearing；To need to only use at one end
Bearing is set in shaft, and the other end need to only be carried by common axis hole, thereby reduce the cost of motor；Only one
Bearing generates noise, reduces the noise of motor operation course middle (center) bearing generation, so that motor has good muting function.
Detailed description of the invention
Fig. 1 is a kind of machine shaft support construction structural schematic diagram of the utility model.
Appended drawing reference: 1, shell；2, shaft；3, bearing；4, lug boss；5, position limiting structure；6, fixing sleeve；7, stator；8,
Rotor；9, axis hole.
Specific embodiment
A kind of machine shaft support construction of the utility model is described further referring to Fig.1.
A kind of machine shaft support construction, including shell 1, shaft 2 and bearing 3, bearing 3 are set in shaft 2, shell 1
One end is provided with the lug boss 4 for loading bearing 3, and one end that shaft 2 passes through bearing 3 is provided with axial for limiting shaft 2
The position limiting structure 5 of play.Bearing 3 is ball bearing.Setting is mutually contradicted between position limiting structure 5 and bearing 3.In position limiting structure 5
Buffer structure is provided between bearing 3, buffer structure is the smooth friction plate being set in shaft 2, and friction plate passes through bullet
Spring is flexibly connected with position limiting structure 5, friction plate can relative limit structure 5 carry out axial displacement, for absorbing position limiting structure 5 and axis
The collision impact between 3 is held, friction plate is provided with equally distributed rubber microparticle, further progress close to the side of bearing 3
Buffering, increases equipment operation stability and muting function.Position limiting structure 5 can be circlip, and circlip is removably secured installation
In shaft 2, facilitates and carry out dismounting maintenance.
In motor operation course, electrical power, stator 7 and the interaction of rotor 8 are run, by the way that axis is arranged on shell 1
3 are held, bearing 3 can carry the rotating operation of shaft 2, reduce shaft 2 and 1 direct friction of shell, it is whole to improve motor
The running stability of body；And shaft 2 can be bonded on 3 inner ring of bearing, avoid fixing sleeve 6 in shaft 2 directly with 1 side wall of shell
CONTACT WITH FRICTION reduces the frictional resistance of motor operation.
By the way that position limiting structure 5 is arranged, position limiting structure 5 can be defined shaft 2, so that the rotation of shaft 2 is more stable；When
When shaft 2 is to 1 inside play of shell, position limiting structure 5 and bearing 3 are bonded to each other compression, and position limiting structure 5 is carried on the interior of bearing 3
On circle, continue the even running for keeping shaft 2.Bearing 3 is set in shaft 2 at one end to need to only use, the other end only needs
It is carried by common axis hole 9, without installing bearing 3, thereby reduces the cost of motor；Only a bearing 3 generates
Noise reduces the noise of the generation of motor operation course middle (center) bearing 3, reduces the noise in motor operation course.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
