To achieve these goals, the invention provides a kind of gear-box, including gear housing and gear-box bonnet, also wrap
Include positioning sleeve and location-plate at least one, described positioning sleeve is by the whole circle that is arranged on described gear housing or part platform
Terrace and fixing described gear-box bonnet, described location-plate is by the groove all or in part that is arranged on described gear housing
Fixing described gear-box bonnet.
Optionally, described positioning sleeve includes positioning sleeve Part I and the perpendicular positioning of described positioning sleeve Part I
Set Part II and and the perpendicular positioning sleeve Part III of described positioning sleeve Part II.
Optionally, described positioning sleeve Part I is close to described gear housing, and described positioning sleeve Part III is close to described
Gear-box bonnet.
Optionally, described positioning sleeve Part I is close to described step surface.
Optionally, the length of described positioning sleeve Part III is longer than the height of described step surface.
Optionally, described positioning sleeve Part II is axially extending along described gear housing.
Optionally, described location-plate radially extending along described gear housing.
Optionally, described location-plate one end covers after being fixed on described gear-box, and the other end is located in described groove.
Optionally, described positioning sleeve and described location-plate are all using being stamped and formed out.
The beneficial effect of gear-box of the present invention：Gear-box of the present invention adopts positioning sleeve and/or location-plate by gear-box bonnet
It is fixed on gear-box, increased the bulk strength of gear-box, impact will not be conducted to housing part, and compared to existing side
Case, cost has obtained obvious reduction.
Brief description
Fig. 1 is the structural representation of the first embodiment of gear-box.
Fig. 2 is the structural representation of the second embodiment of gear-box.
Specific embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with each reality to the present invention for the accompanying drawing
The mode of applying is explained in detail.However, it will be understood by those skilled in the art that in each embodiment of the present invention,
In order that reader more fully understands that the application proposes many ins and outs.But, even if there is no these ins and outs and base
In following embodiment many variations and modification it is also possible to realize each claim of the application technical side required for protection
Case.
The present invention is to solve above-mentioned technical problem, the invention provides a kind of gear-box, in conjunction with Fig. 1 to Fig. 3, to this enforcement
Example is described in detail.Fig. 1 is the structural representation of the first embodiment of gear-box.Fig. 2 is the second embodiment of gear-box
Structural representation.
As described in Figure 1, a kind of gear-box, including gear housing 10 and gear-box bonnet 11, also includes positioning sleeve 12 and determines
Position plate 20 at least one, and described positioning sleeve 12 is consolidated by the step surface 13,15,17 being arranged on described gear housing 10
Fixed described gear-box bonnet 11, described location-plate 20 fixing described tooth by the groove 19 being arranged on described gear housing 10
Roller box bonnet 11, described positioning sleeve 12 includes positioning sleeve Part I 14 and described perpendicular the determining of positioning sleeve Part I 14
Position set Part II 16 and and the perpendicular positioning sleeve Part III 18 of described positioning sleeve Part II 16, described positioning sleeve the
A part 14 is close to described gear housing 10, and described positioning sleeve Part III 18 is close to described gear-box bonnet 11, described positioning
Set Part I 14 is close to described step surface 13,15,17, the length of described positioning sleeve Part III 18 than described step surface 13,
15th, 17 height is long, and described positioning sleeve Part II 16 is axially extending along described gear housing 10, and described location-plate 20 is along institute
State radially extending of gear housing 10, described location-plate 20 one end is fixed on described gear-box bonnet 11, the other end is located at institute
State in groove 19, described positioning sleeve 12 and described location-plate 20 are using being stamped and formed out.
Increase by a positioning sleeve 12 in gear housing 10 outer surface, positioning sleeve 12 adopts stamping parts, and two edges flange, after assembling
It is stuck on the step surface 13,15,17 of gear housing 10, the axial location of axial restraint gear-box bonnet 11 and gear housing 10,
Adopt casing radial compaction positioning sleeve after final assembly, prevent positioning sleeve 12 from coming off.Due to positioning sleeve 12 employ stamping parts and
For thin-wall part, so cost is less with overall dimensions, do not affect package size, and because axial impact will not conduct to casing again,
So it is relatively low to the intensity requirement of casing.
Gear housing 10 increases location-plate 20, location-plate 20 adopts stamping parts, in radially installed internal gear casing 10,
Prevent gear housing 10 bonnet from moving axially, because location-plate 20 radial dimension is less, do not affect gear housing 10 overall dimensions,
Rely on casing compression location-plate after final assembly, prevent location-plate 20 from deviating from, axial impact will not conduct to casing, strong to casing
Degree requires relatively low.
Another kind of embodiment can adopt positioning sleeve and location-plate simultaneously, that is, on the basis of second embodiment, in tooth
The wheel box outer surface setting step similar with first embodiment, is further added by positioning sleeve, thus improving the stability of installation.
Another kind of embodiment, positioning sleeve can be using half-turn or 2/3rds circles；Detent can also be partly recessed
Groove.
