Abstract
The utility model discloses a kind of planet axis for planetary reducer, including output shaft, the planet wheel spindle that is shaped in the flange of the output shaft end and is uniformly distributed in the flange around axis；The output shaft sliding outer cover has pressure ring；The planet wheel spindle is threadingly attached to the flange, and may pass through flange and the pressure ring is pushed to slide axially；Removably the restricted planet wheel spindle of wild card is pierced by the snap ring of flange on the planet wheel spindle；This planet axis can easily and efficiently dismantle the bearing inner race being interference fitted on axis, and not damage components and transmission shaft, lower assembly and maintenance cost significantly.
Description
Technical field
The utility model relates to the components of planetary reducer, specifically a kind of row for planetary reducer
Star axis.
Background technique
Planetary reducer is a kind of common deceleration device, and planet axis is important zero of planetary reducer
Part, functions as that planet carrier supports the rotation of each planetary gear and output block outputs power；In the prior art, planet
Axis generally includes an output shaft and outputs power, and bearing is usually provided on the axle journal of output shaft, carrying output shaft rotation
Frictional resistance is avoided, guarantees transmission efficiency；And since bearing inner race and output shaft are interference fit, the end face of bearing inner race and defeated
The end face gap very little of axial flange out easily damages bearing inner race and part in detachable, so that bearing be caused to scrap and tear open
It is time-consuming and laborious to unload process.
Therefore, in order to solve the above problem, a kind of planet axis for planetary reducer is needed, it can be convenient, fast
Disassembly be interference fitted in the bearing inner race on axis, and do not damage components and transmission shaft, lower significantly assembly and repair at
This.
Utility model content
In view of this, being provided a kind of for planetary gear the purpose of the utility model is to overcome defect in the prior art
The planet axis of retarder can easily and efficiently dismantle the bearing inner race being interference fitted on axis, and do not damage components and
Transmission shaft lowers assembly and maintenance cost significantly.
The planet axis for planetary reducer of the utility model, including output shaft, it is shaped in the output
The flange in shaft end portion and the planet wheel spindle that the flange is uniformly distributed in around axis；The output shaft sliding outer cover has pressure ring；Institute
It states planet wheel spindle and is threadingly attached to the flange, and may pass through flange and the pressure ring is pushed to slide axially；The planet
Removably the restricted planet wheel spindle of wild card is pierced by the snap ring of flange on wheel shaft；
Further, hexagonal cross-section hole is formed on the end face of the planet wheel spindle；
Further, the flange end face is formed with the annular groove for accommodating the pressure ring；
Further, the planet wheel spindle includes coaxial integrally formed major diameter shaft part and path shaft part；The major diameter shaft part
Equipped with the external screw thread for being threadedly coupled with the flange.
The beneficial effects of the utility model are: the planet axis for planetary reducer of the utility model, planetary gear
Axis is threadedly secured on the flange of output shaft, and then snap ring is stuck on output shaft, and snap ring is against on the end face of flange, is used
The length of threaded hole is protruded into limitation planet wheel spindle；When needing to dismantle the bearing inner race being set on the output shaft outside interference fit,
Snap ring can be removed, revolving planet wheel shaft makes planet wheel spindle pass through flange and pushes pressure ring, and pressure ring pushes bearing to slide axially
Certain distance increases the spacing between bearing and flange, convenient for removing bearing using existing extracting tool.
Detailed description of the invention
The utility model is further described with reference to the accompanying drawings and examples:
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Fig. 1 is the structural schematic diagram of the utility model；The planet axis for planetary reducer of the present embodiment includes
Output shaft 6, the flange 3 for being shaped in 6 end of output shaft and the planet wheel spindle that the flange 3 is uniformly distributed in around axis
2；6 sliding outer cover of output shaft has pressure ring 8；The planet wheel spindle 2 is threadingly attached to the flange 3, and may pass through convex
Edge 3 pushes the pressure ring 8 to slide axially；Removably the restricted planet wheel spindle 2 of wild card is worn on the planet wheel spindle 2
The snap ring 7 of flange 3 out；Planet wheel spindle 2 is threadedly secured on the flange 3 of output shaft 6, and snap ring 7 is then stuck in output shaft 6
On, snap ring 7 is against on the end face of flange 3, and the length of threaded hole is protruded into for limiting planet wheel spindle 2；Match when needing to dismantle interference
Housing is closed in 5 inner ring of bearing on output shaft 6, snap ring 7 can be removed, revolving planet wheel shaft 2 passes through planet wheel spindle 2 convex
Edge 3 simultaneously pushes pressure ring 8, and pressure ring 8 pushes bearing 5 to slide axially certain distance, increases the spacing between bearing 5 and flange 3, just
In bearing 5 is removed using existing extracting tool.
In the present embodiment, regular hexagonal section hole 1 is formed on the end face of the planet wheel spindle 2, it, can when dismantling bearing 5
To protrude into a hexagonal cross-section bar in hole, so that planet wheel spindle 2 be driven to rotate.
In the present embodiment, 3 end face of flange is formed with the annular groove for accommodating the pressure ring 8, and when installation, pressure ring 8 can
To be fully accommodated in annular groove, the end face of bearing 5 can be directly against on pressure ring 8, realize axial limiting to bearing 5.
In the present embodiment, the planet wheel spindle 2 includes coaxial integrally formed major diameter shaft part 4 and path shaft part；It is described big
Diameter shaft part 4 is equipped with the external screw thread for being threadedly coupled with the flange 3, and path shaft part is equipped with the ring for installing snap ring 7
Slot.
Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be to this
The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model
It encloses, should all cover in the scope of the claims of the utility model.
