Abstract
The utility model discloses a kind of improved structure taking turns limit assembly planetary wheeling assembly, including planetary wheel carrier, planet wheel spindle, planetary gear, end cap；Described planetary gear is actively socketed on planet wheel spindle, and planet wheel spindle is plugged on planetary wheel carrier, and end cap is fixedly mounted on the end face of planetary wheel carrier；The outer end of described planet wheel spindle is provided with an annular flange flange extended radially outward, and the outer of this annular flange flange exceeds planet wheel spindle cross section holding on the end face face of planetary wheel carrier.Owing to this utility model is provided with an annular flange flange extended radially outward on the outer end of planet wheel spindle, this annular flange flange holding is on the end cap end face of harder material, thus limits planet wheel spindle and rotate, and is effectively increased the service life of wheel limit assembly.
Description
Technical field
This utility model relates to a kind of engineering machinery, particularly relates to a kind of improved structure taking turns limit assembly planetary wheeling assembly.
Background technology
As shown in Figure 1, the wheel limit assembly planetary wheeling assembly commonly used mainly is made up of parts such as planetary wheel carrier 1 ', steel ball 2 ', planet wheel spindle 3 ', planetary gear 4 ', end caps 5 ', this wheel limit assembly planetary wheeling assembly commonly used uses traditional steel ball 2 ' of using and is pre-installed on planet wheel spindle 3 ' and packs on planetary wheel carrier 1 ' again, limits the relative rotation between planet wheel spindle 3 ' with planetary wheel carrier 1 ' with this.Planetary wheel carrier 1 ' is generally softer by QT450-10 material because of the particularity of structure, and steel ball 2 ' is then bearing steel, loader forward-reverse frequently when operation, and steel ball 2 ' constantly impact planetary wheel carrier 1 ' causes the earlier period damage of planetary wheel carrier 1 '.
Summary of the invention
The purpose of this utility model is to provide the improved structure of wheel limit assembly planetary wheeling assembly of length in a kind of service life.
For achieving the above object, technical solution of the present utility model is:
A kind of improved structure taking turns limit assembly planetary wheeling assembly, including planetary wheel carrier, planet wheel spindle, planetary gear, end cap；Described planetary gear is actively socketed on planet wheel spindle, and planet wheel spindle is plugged on planetary wheel carrier, and end cap is fixedly mounted on the end face of planetary wheel carrier；Described planet wheel spindle is provided with an annular flange flange extended radially outward towards the side of end cap, the outer of this annular flange flange exceeds planet wheel spindle cross section holding on the end face of planetary wheel carrier, the inner top surface of described end cap is provided with one and limits the most spacing recess of planet wheel spindle, planet wheel spindle annular flange flange and the mutual holding of spacing recess in end cap.
Further, the annular flange flange lateral profile of described planet wheel spindle is non-circular.
Further, the lateral profile of the annular flange flange of described planet wheel spindle is circular, and its outer circumference is provided with a breach, and the spacing recess in described end cap is annular groove, and this annular groove is just and the mutual holding of breach outside the annular flange flange of planet wheel spindle.
After using such scheme, owing to this utility model is mainly made up of parts such as planetary wheel carrier, planet wheel spindle, end caps, the outer end of planet wheel spindle is provided with an annular flange flange extended radially outward, this annular flange flange and the mutual holding of spacing recess of rubbing surface of end cover, thus limit planet wheel spindle and rotate, it is effectively increased the service life of wheel limit assembly.
With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings.

Detailed description of the invention
As shown in Fig. 2-1 Fig. 4, this utility model is a kind of improved structure taking turns limit assembly planetary wheeling assembly, including planetary wheel carrier 1, planet wheel spindle 2, planetary gear 3, end cap 4.
In described planet wheel spindle 2 is set in planetary wheel carrier 1 and to being externally provided with an extension, planetary gear 3 is actively socketed on planet wheel spindle 2, and end cap 4 is fixedly mounted on the end face of planetary wheel carrier 1.
The extension of described planet wheel spindle 2 is provided with an annular flange flange extended radially outward 21, and the outer of this annular flange flange 21 exceeds planet wheel spindle 2 cross section, and therefore planet wheel spindle 2 can be expert on the end face of star wheel frame 1 in holding.
In order to avoid planet wheel spindle 2 relatively rotates with planetary wheel carrier 1, the annular flange flange of planet wheel spindle 2 can be set to non-circular component, such as triangle, rectangle, (not shown), the medial surface of described end cap 4 is provided with just and the spacing recess of the mutual holding of annular flange flange, owing to annular flange flange is non-circular, and end cap 4 is fixed on planetary wheel carrier 1, it can be ensured that planet wheel spindle 2 will not relatively rotate with planetary wheel carrier 1；The present invention also provides for another embodiment simultaneously, the lateral profile of the annular flange flange 21 of described planet wheel spindle 2 is circular, and its outer circumference is provided with a breach 22, the described spacing recess in end cap 4 is annular groove 41, this annular groove 41 just and the mutual holding of breach 22 outside the annular flange flange 21 of planet wheel spindle 2, so that it is guaranteed that planet wheel spindle 2 will not relatively rotate with planetary wheel carrier 1.
Emphasis of the present utility model is that the planet wheel spindle using one end to have special-shaped outline.
The above, it is only this utility model preferred embodiment, therefore can not limit, with this, the scope that this utility model is implemented, the equivalence change i.e. made according to this utility model claim and description with modify, all should still belong in the range of this utility model patent contains.
