Description
Technical field
The present invention relates to a kind of gearing, particularly relate to a kind of gear improving stability.
Background technique
Existing gear is same structure all over, such as forging gear is the structure of forging gear all over, and cast gear is the structure of cast gear all over.
Although cast gear cost is lower, and vibrations when structural property is Absorbable rod pinion rotation, because the precision of casting is lower, therefore quality is not very stable.Although and forge gear intensity and durability higher, the precision of size is higher, anti seismic efficiency poor and produce required for cost quite high.
Therefore those skilled in the art endeavour and the higher and compound gear that anti seismic efficiency is good of a kind of precision of exploitation.
Summary of the invention
Because the above-mentioned defect of prior art, technical problem to be solved by this invention is to provide the higher and compound gear that anti seismic efficiency is good of precision.
For achieving the above object, the invention provides a kind of gearing improving stability, comprise wheel and forging ring gear in casting, in casting, wheel offers axis hole, the inwall of axis hole arranges and offers the first keyway; The module of forging ring gear is 5;
In casting, the outer wall of wheel offers two the second keyways, two the second keyways are symmetrical, the top of two the second keyways is provided with two threaded perforations, and two the second keyways lay respectively between two threaded perforations, and threaded perforations is arranged on the edge of wheel in casting;
The internal diameter of forging ring gear with take turns identical in casting, forged teeth ring set is located at that casting is interior to be taken turns, and the excircle forging ring gear is provided with several double wedges; The inwall of forging ring gear is provided with two symmetrical key-grooves, the through top to forging ring gear, upper end of key-groove, key-groove and the second keyway one_to_one corresponding; Be provided with connecting key between each second keyway and each key-groove, the height of taking turns in the height of connecting key and casting is suitable; The top of each two the second keyways is provided with card, and card is provided with bolt, and bolt is by being connected and fixed with threaded perforations through after the card punching on card.
In order to improve compactness of the present invention and anti seismic efficiency, forging ring gear is suitable with the height of card higher than the height of wheel in casting.
The invention has the beneficial effects as follows: also have good anti seismic efficiency while the present invention effectively improves precision to have structure simple, reforming cost is low waits beneficial effect.

Embodiment
Below in conjunction with drawings and Examples
The invention will be further described:
As Figure 1-Figure 4, a kind of gearing improving stability, comprise wheel 10 and forging ring gear 20 in casting, in casting, wheel 10 offers axis hole 11, the inwall of axis hole 11 arranges and offers the first keyway 12; The module of forging ring gear 20 is 5;
In casting, the outer wall of wheel 10 offers two the second keyways 13, two the second keyways 13 are symmetrical, the top of two the second keyways 13 is provided with two threaded perforations, 14, two the second keyways 13 and lays respectively between two threaded perforations 14, and threaded perforations 14 is arranged on the edge of wheel 10 in casting;
The internal diameter of forging ring gear 20 is identical with taking turns 10 in casting, and forging ring gear 20 is set in casting on wheel 10, and the excircle of forging ring gear 20 is provided with several double wedges 27; The inwall of forging ring gear 20 is provided with the through top to forging ring gear 20, upper end of two symmetrical key-groove 21, the key-grooves 21, key-groove 21 and the second keyway 13 one_to_one corresponding; Be provided with connecting key 24 between each second keyway 13 and each key-groove 21, take turns in the height of connecting key 24 and casting 10 height suitable; The top of each two the second keyways 13 is provided with card 25, card 25 is provided with bolt 26, and bolt 26 is connected and fixed by and threaded perforations 14 rear through the card punching 251 on card 25;
Lower edge along the inner peripheral surface of forging ring gear 20 is provided with one week edge clipping 22; The upper limb of the inner peripheral surface of forging ring gear 20 is provided with one week embedding ditch 23 of card; The outer rim of each card 25 embeds the embedding ditch 23 of card.Forging ring gear 20 is suitable with the height of card 25 higher than the height of wheel 10 in casting.
Forge in ring gear 20 and casting between taking turns 10 detachable in the present invention, after the double wedge 27 of forging ring gear 20 weares and teares, forging ring gear 20 can be taken off replacing, reduce maintenance cost, in addition, will the dimensioned of interior wheel 10 be cast, when needing the gear using various outer diameter, dismantle original forging ring gear 20 and change the interior wheel 10 of casting that the forging ring gear 20 with various outer diameter can continue to use inner side, thus improve the utilization rate of product, reduce expense.When the present invention uses, the anti seismic efficiency of wheel 10 in casting can be utilized, absorb from vibrations during gear transmission, there is provided accurate and durable double wedge 27 carries out the engagement of gear to forge ring gear 20 again, there is preferably effect, reduce owing to casting interior fraction of taking turns 10 simultaneously, thus effectively saved manufacture cost.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design according to the present invention can make many modifications and variations without the need to creative work.Therefore, all technician in the art, all should by the determined protection domain of claims under this invention's idea on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment.
