Abstract
The utility model relates to a kind of straightener overlength double helical tooth distributor boxes, including cabinet, input shaft, multistage cylindrical gear drive and multiple output shafts, input shaft is driven an output shaft through the above cylindrical gear drive of level-one, one output shaft is driven next output shaft through the above cylindrical gear drive of level-one, and every level-one output shaft is driven next output shaft of this grade of output shaft through the above cylindrical gear drive of level-one；Input shaft is equipped with upper and lower two gear, it is upper and lower two gears engagement, speed ratio 1:1 drive mechanism that input shaft, which is engaged with cylindrical gear drive, cylindrical gear drive with the gear of output between centers, and gear engagement is herringbone tooth engagement, the double helical tooth of upper and lower two gear is symmetrical above and below on input shaft.Its structure is simple, and carrying is big, is hardly damaged, long service life.
Description
Technical field
The utility model relates to a kind of speed reducer, specifically a kind of straightener overlength double helical tooth distributor box.
Background technique
Common one into the speed ratio 1:1 having more spur gear cylinder transmission distributor box is driven on straightener, is being applied to
When the big straightening work of bearing requirements, due to needing 1:1 to distribute Multi-stage transmission, carrying easily causes drive mechanism to damage greatly, shadow
It rings and uses.
Summary of the invention
It is simple that the utility model provides a kind of structure, and carrying is big, is hardly damaged, straightener overlength with long service life
Double helical tooth distributor box.The technical solution adopted in the utility model is: a kind of straightener overlength double helical tooth distributor box, including case
Body, input shaft, multistage cylindrical gear drive and multiple output shafts, it is characterised in that: the input shaft is through more than level-one circle
One output shaft of Column gear transmission mechanism driving, an output shaft are driven next output shaft through the above cylindrical gear drive of level-one,
Every level-one output shaft is driven next output shaft of this grade of output shaft through the above cylindrical gear drive of level-one；It is set on input shaft
There is upper and lower two gear, input shaft engages with cylindrical gear drive, cylindrical gear drive with the gear of output between centers
It is engaged for upper and lower two gear, speed ratio 1:1 drive mechanism, and gear engagement is herringbone tooth engagement, upper and lower two gear on input shaft
Double helical tooth it is symmetrical above and below.
Further, output shaft stretches out cabinet and exports as level-one.
The utility model is using input shaft and cylindrical gear drive, cylindrical gear drive and the tooth for exporting between centers
Wheel engagement is upper and lower two gears herringbone tooth engagement, speed ratio 1:1 drive mechanism, and the carrying of herringbone tooth engagement is big, upper and lower two gear
Double helical tooth it is symmetrical above and below, can be further improved engaging structure bearing capacity, stable drive, long service life is suitble to 1:1 transmission
Straightener with overlength distributor box use.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
In figure: cabinet 1, input shaft 2, upper input gear 3, lower input gear 4, jackshaft 5, upper intermediate gear 6, lower centre
Gear 7, output shaft 8, upper output gear 9, lower output gear 10.
Specific embodiment
It is described further below in conjunction with drawings and examples.
Shown in Fig. 1: a kind of straightener overlength double helical tooth distributor box include cabinet 1, input shaft 2, upper input gear 3, under
Input gear 4, multistage jackshaft 5, upper intermediate gear 6, lower intermediate gear 7, multi-level output axis 8, upper output gear 9, lower output
Gear 10.Input shaft 2 is equipped with upper input gear 3, lower input gear 4, is symmetrically arranged on upper input gear 3, lower input gear 4
Double helical tooth, upper input gear 3, lower input gear 4 respectively on jackshaft 5 upper input gear 3, lower input gear 4 is with speed ratio
1:1 double helical tooth engaged transmission, upper input gear 3, lower input gear 4 respectively with the upper output gear 9 on output shaft 8, lower output
Gear 10 is with speed ratio 1:1 double helical tooth engaged transmission, after output shaft 8 by above-mentioned engaging structure after jackshaft transmission more than level-one
Level-one output shaft, every level-one output shaft, which is passed through level-one jackshaft, engages the next output shaft for moving this grade of output shaft, input shaft 2,
Multi-level output axis 8,5 same level face of multistage jackshaft are supported in cabinet 1.
Output shaft stretches out cabinet and exports as increased level-one in the present embodiment.
Claims (2)
