Abstract
The utility model relates to a gearbox of forward-reverse output composite shafts, which belongs to a gear transmission device. A composite output shaft comprises a core shaft (6) and a hollow sleeve shaft (7) with an identical shaft line. An input shaft is assembled with a gear (9) and a gear (1). The gear (9) is meshed with a gear (10) on the core shaft. The gear (1) realizes transmission through changing the direction of a gear (3) which is assembled on a transmission shaft and a gear (5) on the sleeve shaft. The rotary directions of the core shaft and the sleeve shaft are opposite. Therefore, the utility model has the effects of enriching the power output mode of the gearbox of forward-reverse output composite shafts, satisfying the specific purpose of a relevant device, and widening functions and applicable range.
Description
" technical field " the utility model relates to a kind of gear drive, particularly belongs to a kind of forward and reverse output composite shaft gear-box.
Gear-box that " background technique " is traditional or gearbox pattern are varied, and the main distinction is parallel shaft arrangement or vertical shaft layout, but the input shaft of this dual mode and output shaft are single shaft.As mechanically operated foundation, this input of conventional gearbox, outputting power monotony have limited effect, function and the purposes of associated machines greatly.
" summary of the invention " the purpose of this utility model promptly is to provide a kind of novel forward and reverse output composite shaft gear-box, enriches the gear-box power way of output to overcome the narrow limitation of conventional gearbox, to reach, and widens the purpose of relevant device function and Applicable scope.
Forward and reverse output composite shaft gear-box disclosed in the utility model, adopt parallel shaft arrangement, it is characterized in that, arrange input shaft (2), changed course transmission shaft (4) and compound output shaft in the said casing (8) successively, so-called compound output shaft comprises the mandrel (6) of coaxial line and the sleeve (7) of hollow; Be equipped with gear (9) and gear (1) on the input shaft, gear (10) engagement on gear (9) and the mandrel; Gear (1) is realized transmission by the gear (3) that assembles on the changed course transmission shaft with the gear (5) on the sleeve.
Because gear-box disclosed in the utility model has been taked compound output shaft, therefore and its mandrel is opposite with turning to of sleeve, has to enrich the gear-box power way of output, can satisfy the relevant device specific use, widen the effect of its function and Applicable scope.
" description of drawings " accompanying drawing is a sectional drawing of the present utility model.
" embodiment " is further described at specific embodiment of the utility model below in conjunction with accompanying drawing:
As shown in drawings, forward and reverse output composite shaft gear-box disclosed in the utility model adopts parallel shaft arrangement, is furnished with input shaft (2), changed course transmission shaft (4) and compound output shaft in the casing (8) successively.Compound output shaft comprises mandrel (6) and sleeve (7).Mandrel is a solid body, and sleeve is the tubulose of hollow, is sleeved on the mandrel outside, both same axis.Be equipped with gear (9) and gear (1) on the input shaft.Gear (10) engagement on gear (9) and the mandrel constitutes first auxiliary driving relation; Gear (5) engagement on gear (3) engagement, gear (3) and the sleeve that assembles on gear (1) and the changed course transmission shaft constitutes second auxiliary driving and concerns.
In the embodiment shown in the figures, the velocity ratio of the gear (10) on gear (9) and the mandrel is 1: 1, i.e. the input of first auxiliary driving relation, output are than being 1: 1.Velocity ratio between gear (1) and the gear (3), between gear (3) and the gear (5) was all 1: 1, and therefore the input of second auxiliary driving relation, output are 1: 1 than also.But, this drive connection is not unique, input and output are than fixing, according to the mandrel of compound output shaft and the different needs of sleeve rotating speed, can change the velocity ratio of above-mentioned driving gear, the input, output that make first auxiliary driving relation and second auxiliary driving relation are than different, and promptly mandrel is different with the rotating speed of sleeve, realize differential effect, its principle is the same.
Claims (2)
1, a kind of forward and reverse output composite shaft gear-box, adopt parallel shaft arrangement, it is characterized in that arrange input shaft (2), changed course transmission shaft (4) and compound output shaft in the said casing (8) successively, so-called compound output shaft comprises the mandrel (6) of coaxial line and the sleeve (7) of hollow; Be equipped with gear (9) and gear (1) on the input shaft, gear (10) engagement on gear (9) and the mandrel; Gear (1) is realized transmission by the gear (3) that assembles on the changed course transmission shaft with the gear (5) on the sleeve.
2, a kind of forward and reverse output composite shaft gear-box according to claim 1, it is characterized in that, the ratio of the input output of first auxiliary driving relation that said gear (9) and gear (10) constitute, different with the ratio of the input output of second auxiliary driving relation that is made of gear (1), gear (3), gear (5), the mandrel of promptly compound output shaft is different with the rotating speed of sleeve.
