Description
Technical field
The utility model is related to micromotor technical field, more particularly to a kind of planetary gear reducing mechanism of miniature motor
Output precision.
Background technology
The output precision of planetary gear reducing mechanism of miniature motor, including output shaft and planet stent, the spindle nose of output shaft
Using interference fit, usual way is to be press-fitted to form output shaft with planet stent after annular knurl on axis for internal control with planet stent
Component.It is herein to transmit torque using interference fit, the purpose of annular knurl.But the dimensional tolerance of annular knurl is difficult to accurately control
System, product qualified rate are low.Planet stent is set to crack and fail if being interference fitted conference, if interference fit is too small, output shaft
The internal control of spindle nose and planet stent skids and loses the function of transmitting torque.If the spindle nose of output shaft is set as D types, with output shaft
The external component of connection is fragile, to lose the function of motor.
Utility model content
The main purpose of the utility model is to propose a kind of output precision of planetary gear reducing mechanism of miniature motor, it is intended to
The structure for changing traditional output precision, improves the qualification rate of torque and product that output precision is born.
To achieve the above object, the utility model proposes a kind of planetary gear reducing mechanism of miniature motor output group
Part, including output shaft, planet stent and the planetary gear on planet stent.The planet stent is equipped with for pacifying
The planetary mounting groove is filled, described planetary one end is axially mounted to along it in the mounting groove, the planet
The other end of gear is equipped with a pressing plate, and the planet stent is equipped with the boss for installing the pressing plate, the pressing plate and institute
Planet stent is stated to be fixedly connected.The output shaft is connect with outside manufacture, and is offered on the output shaft for installing outside
The structure of the inner spline groove of product, the inner spline groove is adapted with outside manufacture.The output shaft is set with the planet stent
Set as one structure.
Preferably, the output shaft is set as integral structure made of powder metallurgy with the planet stent.
Preferably, the output shaft is set as the integral structure of injection molding with the planet stent.
Preferably, the material of the output shaft and the planet stent is set as No. 45 steel.
Compared with prior art, the utility model has the beneficial effects that:Output shaft and planet stent in output precision are adopted
With the structure of one, can effectively power transmission torque, avoid the interference problem generated due to traditional approach, influence the transmission of torque
With the yield of product.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, the structure that can also be shown according to these attached drawings obtains other attached drawings.
Fig. 1 is the overall structure diagram of the utility model output precision;
Fig. 2 is the overall structure of the explosion figure of the utility model output precision;
Fig. 3 is the structural schematic diagram of planet stent one end of the utility model output precision;
The embodiments will be further described with reference to the accompanying drawings for the realization, functional characteristics and advantage of the utility model aim.
Specific implementation mode
A kind of output precision for planetary gear reducing mechanism of miniature motor that the present embodiment proposes, including output shaft 1, planet
Holder 2 and the planetary gear 4 on planet stent 2.The planet stent 2 is equipped with for installing the planetary gear 4
Mounting groove 201, one end of the planetary gear 4 is axially mounted to along it in the mounting groove 201, the planetary gear 4
The other end is equipped with a pressing plate 3, and the planet stent 2 is equipped with the boss 202 for installing the pressing plate 3, the pressing plate 3 and institute
Planet stent 2 is stated to be fixedly connected.The output shaft 1 is connect with outside manufacture, and is offered on the output shaft 1 outer for installing
The inner spline groove 101 of portion's product, the structure of the inner spline groove 101 are adapted with outside manufacture.The output shaft 1 and the row
The setting of prong frame 2 is structure as a whole.
Pressing plate 3, which is mounted on planet stent 2, can form the space for installing planetary gear 4, and planetary gear 4 is fixed
Between pressing plate 3 and planet stent 2.The planetary gear 4 is set as three, is distributed on the planet stent 2, realizes motor
Internal power transmits, and improves the stability that power transmits.Meanwhile the structure being integrated is arranged in output shaft 1 and planet stent 2,
Traditional interference fit connection is changed, the ability that output precision bears torque is improved, meanwhile, it effectively prevents due to interference
Coordinate a series of problems generated, influences the transmission of torque.The yield for improving product reduces the scrappage of product.Into one
Step ground, output shaft 1 are set as inner spline groove 101 with the connecting pin of outside manufacture and connect, and change traditional outer flat key connection knot
Structure makes uniform force between output shaft 1 and product, avoids damage product and output shaft 1, and improve output precision uses the longevity
Life.
Further, output shaft 1 is set as one of integral structure or injection molding made of powder metallurgy with planet stent 2
Body structure.By the way of powder metallurgy or injection molding, production efficiency is substantially increased, output precision can be carried out large quantities of
Amount production greatly reduces into production cost.
Further, output shaft 1 and the material of planet stent 2 are set as No. 45 steel, substantially increase output shaft 1 and planet
The rigidity of holder 2 improves the service life of output precision.
It these are only the preferred embodiment of the utility model, it does not limit the scope of the patent of the present invention, every
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in
Other related technical areas are equally included in the patent within the scope of the utility model.
