Description
Technical field
The utility model is related to a kind of starting motor, and motor gear bearing press mounting frock is started more particularly, to one kind.
Background technology
It is well known that the starting of engine needs the support of external force, automobile starter is exactly to play this role.Greatly
Said on body, starter realizes whole starting process with three parts.Dc motor introduce the electric current from battery and
The drive gear of starter is set to produce mechanical movement；Drive gear is engaged into flywheel ring gear by transmission mechanism, while can be in hair
Disengaged automatically after engine start；The break-make of starter circuit is then controlled by an electromagnetic switch.
Planetary gear is the common components for starting motor.At present, the installation of the existing planetary gear bearing for starting motor
It is many using manually being press-fited, there is inefficiency and press-fit concentricity and can not ensure.
Utility model content
The purpose of this utility model is to provide a kind of starting motor gear bearing press mounting frock, to solve in the prior art
Start the problem of motor planetary gear-bearing press-fits inefficiency and the concentricity difference of presence.
For up to this purpose, the utility model uses following technical scheme：
One kind starts motor gear bearing press mounting frock, and it includes base and support tube, and the base is fixed on the branch
The bottom of cylinder is supportted, wherein, formed and be provided with accommodating cavity, the accommodating cavity described in stretching between the support tube and the base
Support tube and motion bar moving up and down, the planetary endoporus of major diameter fit of the motion bar are set, the motion bar
Top be provided with the top of the bearing suit portion of fitted bearing internal diameter, the support tube offer it is concentric with the accommodating cavity
Step cutting pattern portion, planetary external diameter described in the major diameter fit of the stage portion is set, in the activity in the accommodating cavity
The elastomeric element resetted for motion bar is provided between bar and base.
Especially, correspondence offers screwed hole on the base and support tube, and company is fixed by fixing bolt in both
Connect.
Especially, the bottom of the motion bar is provided with round boss, is housed described in the major diameter fit of the round boss
The internal diameter of chamber is set, and the correspondence round boss in the support tube in being provided with positive stop lug boss.
Especially, the elastomeric element uses metal coil spring, and one end of the helical spring is resisted against the circle
The bottom of boss, the other end is resisted against on the base.
The beneficial effects of the utility model are, described compared with prior art to start motor gear bearing press mounting frock not only
Simple in construction, manufacturing cost is low；And be easy to operation, press-fit efficiency high, ensure that by last item hold with it is planetary concentric
Degree.

Embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by embodiment.
Refer to shown in Fig. 1, Fig. 1 is the starting motor gear bearing press mounting that the utility model embodiment 1 is provided
The structural representation of frock.
In the present embodiment, one kind, which starts motor gear bearing press mounting frock, includes base 1 and support tube 2, the He of base 1
Correspondence offers screwed hole on support tube 2, and both are fixedly connected by fixing bolt.The support tube 2 and the base 1
Between form accommodating cavity 3, the stretching support tube and motion bar moving up and down 4, the work are provided with the accommodating cavity 3
The endoporus of the major diameter fit planetary gear 5 of lever 4 is set, and the bottom of the motion bar 4 is provided with round boss 6, the circle
The internal diameter of accommodating cavity 3 described in the major diameter fit of boss 6 is set, and the correspondence round boss 6 is limited in setting in the support tube 2
Position boss 7.
The top of the motion bar 4 is provided with the bearing suit portion 9 of the internal diameter of fitted bearing 8, and the top of the support tube 2 is opened
Provided with the step cutting pattern portion 10 concentric with the accommodating cavity 3, the external diameter of planetary gear 5 described in the major diameter fit of the stage portion 10
Set, be provided with the helical spring resetted for motion bar 4 in the accommodating cavity 3 between the round boss 6 and base 1
11, one end of the helical spring 11 is resisted against the bottom of the round boss 6, and the other end is resisted against on the base 1.
When press-fiting, in the stage portion 10 that planetary gear 5 is positioned over to the end of support tube 2, bearing 8 is then placed on institute
State in bearing suit portion 9, applying pressure from top to bottom moves down bearing 8 and motion bar 4, and bearing 8 is placed on into the planet
In the endoporus of gear 5, revocation pressure coil spring 11 resets motion bar 4.
Above example is to elaborate general principle of the present utility model and characteristic, and the utility model is not by above-mentioned example
Limitation, on the premise of the utility model spirit and scope are not departed from, the utility model also has various change and change, these changes
Change and change and both fall within the range of claimed the utility model.Scope is claimed in the utility model will by appended right
Ask book and its equivalent thereof.
