Description
Technical field
The utility model relates to a kind of major and minor transmission integrated device, for the drive mechanism of gear-box.Belong to mechanical equipment technical field.
Background technique
The transmission device of the existing drive mechanism for gear-box overlaps independently device by two and forms, as shown in Figure 6, it is a set of is main transmission, another set of is auxiliary driving, when gear-box normally runs, and main transmission work, when overhauling or main transmission goes wrong, auxiliary driving works, and transmission device adopts two covers that it independently can be caused to take up room greatly, and can be unstable in the lower operation that is in an emergency.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides transmission device, and it adopts major and minor transmission integrated device, transmission device is taken up room little, and can stablize in the lower operation that is in an emergency.
The purpose of this utility model is achieved in that
A kind of major and minor transmission integrated device, comprise auxiliary-motor, output shaft and casing, it is characterized in that: described major and minor transmission integrated device also comprises splined shaft, worm gear pair and sliding sleeve, described worm gear pair is arranged on splined shaft, described sliding sleeve is set on splined shaft, sliding sleeve respectively with the flange of worm gear pair and the spline fitted of splined shaft, one end of splined shaft is connected with mair motor, the other end is connected with output shaft, and described auxiliary-motor is connected with worm gear pair.
A kind of major and minor transmission integrated device of the utility model, its spline and flange are coordinated by gears meshing with the inwall of sliding sleeve respectively.
A kind of major and minor transmission integrated device of the utility model, its casing is provided with plectrum, and plectrum is connected with sliding sleeve.
Compared with prior art, the beneficial effects of the utility model are:
1. a kind of major and minor transmission integrated device of the utility model, auxiliary driving of the present utility model and main transmission share a transmission main shaft, therefore can reduce the space that transmission device takies.
2. a kind of major and minor transmission integrated device of the utility model, switches two kinds of working staties by slip sliding sleeve, under being in an emergency, easy to operate, and stable.

Embodiment
See Fig. 1-5, the utility model relates to a kind of main, auxiliary driving integrated device, it comprises auxiliary-motor 1, splined shaft 2, worm gear pair 3, sliding sleeve 4, output shaft 5 and casing 6, auxiliary-motor 1, splined shaft 2, worm gear pair 3, sliding sleeve 4 and output shaft 5 are all arranged on casing 6, described worm gear pair 3 is arranged on the right part of splined shaft 2 by bearing, described sliding sleeve 4 is set in the middle part of splined shaft 2, sliding sleeve 4 coordinates with the flange 3.1 of worm gear pair 3 and the spline 2.1 of splined shaft 2 respectively, one end of described splined shaft 2 is connected with mair motor, the other end of splined shaft 2 is connected with output shaft 5, described auxiliary-motor 1 is connected with worm gear pair 3.
Working principle:
Normal working: mair motor drives splined shaft 2 to rotate, now sliding sleeve 4 be positioned at worm gear pair 3 flange 3.1 on and be in disengaged condition with the spline 2.1 of splined shaft 2, splined shaft 2 drives output shaft 5 to rotate by gear transmission and exports.
Mair motor goes wrong or inspecting state: mair motor quits work, by the plectrum stirred on casing 6, sliding sleeve 4 is slided to spline 2.1, now sliding sleeve 4 engages with the flange 3.1 of spline 2.1 and worm gear pair 3 simultaneously, auxiliary-motor 1 is started working, worm gear pair 3 is driven to rotate, because sliding sleeve 4 engages with the flange 3.1 of spline 2.1 and worm gear pair 3 simultaneously, under the effect of sliding sleeve 4, splined shaft 2 drives output shaft 5 rotation to export by gear transmission.
Structure diagram is see Fig. 7, auxiliary driving 9 of the present utility model and main transmission 8 share a transmission main shaft, the spline slide formula clutch 11 that transmission main shaft is arranged switches two kinds of working staties, and therefore transmission device takes up room little, and can stablize in the lower operation that is in an emergency.
