Abstract
It the utility model is related to a kind of parallel axes two-stage worm screw supplementary reduction, it is characterized in that, two-stage transmission mechanism is set in decelerating chassis body, the first order and second level worm gear pair are distributed on the diagonal of box body of speed reducer, ensure first order worm axis and second level worm gear diameter parallel；First order worm axis and second level worm gear diameter parallel；Motor or motor driving first order worm screw work, first order worm screw are transmitted motion on first order worm gear, and first order worm gear is output on the worm screw of the second level, is finally exported by second level worm drive second level worm gear.Parallel axes worm screw supplementary reduction of the present utility model, on the basis of single-stage worm screw supplementary reduction, further optimize structure, overcome worm type of reduction gearing input shaft and the not parallel problem of output shaft, reduce the volume and weight of decelerator using new monoblock type body structure, ensure to occur without swing after worm screw stress under poor working conditions from new bearing installation form.
Description
[technical field]
Technical field of mechanical transmission is the utility model is related to, specifically a kind of parallel axes two-stage worm screw supplementary reduction.
[background technology]
The general gearratio of single-stage worm reducer is in 5-80, because worm tooth is continuously helical tooth, it and worm gear
Tooth progresses into engagement and is gradually backed out engagement, while the tooth logarithm engaged is again more, therefore shock loading is small, and transmission is flat
Surely, noise is low.The angle of worm axis and worm gear axis is generally 90 °, and worm axis can not be met with worm gear diameter parallel
It is required that and be driven it is bigger when, powerdriven requirement can not be met.
A kind of parallel axes two-stage worm screw supplementary reduction is on the basis of original single-stage worm screw supplementary reduction, further optimization
Structure, the problem of overcoming reducer input shaft and not parallel output shaft, the small volume of decelerator, in light weight, gearratio is big.
[content of the invention]
The defects of the purpose of this utility model is to overcome prior art to exist, there is provided a kind of structure novelty, degree of integration
High parallel axes two-stage worm screw supplementary reduction.
To achieve the above object, it is related to a kind of parallel axes two-stage worm screw supplementary reduction, including reduction case, its feature exist
In setting two-stage transmission mechanism in reduction-gear housing body, the two-stage transmission mechanism includes：First order worm gear pair, second level worm gear pair.
Second level worm screw is the output shaft of first order worm gear, reaches the purpose of series connection by this way.
The first order and second level worm gear pair are distributed on the diagonal of box body of speed reducer, ensure first order worm axis and the
Second-stage worm gear diameter parallel.
Motor or motor driving first order worm screw subtask, first order worm gear pair are transmitted motion on first order worm gear,
First order worm gear is output on the worm gear pair of the second level, finally by the driving second level worm gear output of second level worm gear pair.
The small flat worm gear pair of centre-to-centre spacing does the first order；The big worm gear pair of centre-to-centre spacing does the second level.
The worm bearing of second level worm gear pair, it for a pair of face-to-face taper roll bearings, the other end is one to use one end
Single-row tapered roller bearing, the middle structure type for a cylinder roller bearing.
The resultant gear ratio of two-stage transmission reaches 25-6400 speed ratio.
The first order worm gear pair and second level worm gear pair use forge piece.
Parallel axes worm screw supplementary reduction of the present utility model, on the basis of monopole worm screw supplementary reduction, further optimization
Structure, overcome worm type of reduction gearing input shaft and the not parallel problem of output shaft, subtracted using new monoblock type body structure
The volume and weight of fast device, ensure to occur without swing after worm screw stress under poor working conditions from new bearing installation form.
[brief description of the drawings]
Fig. 1 is structural representation of the present utility model
Description of reference numerals
1 second level worm gear, 2 first order worm gear pairs, 3 first order worm gears, 4 second level worm gear pairs, 5 single-row tapered roller axles
Hold, 6 cylinder roller bearings, 7 reduction cases, 8 a pair of the taper roll bearings arranged face-to-face.
[embodiment]
The technical solution of the utility model is further elaborated in conjunction with drawings and Examples, it is believed that to art technology
It is clear for personnel.
As shown in figure 1, this parallel axes two-stage worm screw supplementary reduction is made up of two-stage worm gear pair.
Including reduction case, it is characterised in that set secondary drive mechanism, the secondary drive mechanism in decelerating chassis body
Including：First order worm gear pair, second level worm gear pair, both, which are sequentially connected in series, forms,
The first order and second level worm gear pair are distributed on the diagonal of box body of speed reducer, ensure first order worm axis and the
Second-stage worm gear diameter parallel；Motor or motor driving first order worm screw work, first order worm screw transmit motion to first order snail
On wheel, first order worm gear is output on the worm screw of the second level, is finally exported by second level worm drive second level worm gear.Decelerator moistens
Sliding mode is lubricated using oil sump.
The small worm gear pair of centre-to-centre spacing does the first order；The big worm gear pair of centre-to-centre spacing does the second level.
The worm bearing of second level worm gear pair, it for a pair of face-to-face taper roll bearings, the other end is one to use one end
Single-row tapered roller bearing, the middle structure type for a cylinder roller bearing.
The gearratio of two-stage transmission reaches 25-6400 speed ratio.
The worm gear pair uses forge piece.
Its specific transmission process is：Motor or motor driving first order worm screw subtask, first order worm gear pair will move
It is delivered on first order worm gear, first order worm gear is output on the worm gear pair of the second level, finally drives second by second level worm gear pair
Level worm gear output.This transmission process ensure that first order worm axis and second level worm gear diameter parallel.
