Abstract
The invention discloses a helical gear speed reducing mechanism which aims to solve the problems that a reduction box for coaxial speed reduction is complex in structure and large in occupied space in the prior art. The helical gear speed reducing mechanism comprises a rack and further comprises a driving shaft, a driven shaft and a connecting rod, wherein the axial line of the driven shaft is identical with that of the driving shaft, and the connecting rod is arranged between the driving shaft and the driven shaft and is perpendicularly fixed to the driven shaft. A first gear is arranged at one end of the driving shaft, second gears are arranged at the two ends of the connecting rod, the middle of the connecting rod is fixed to the driven shaft, a third gear is fixedly arranged on the rack, the third gear and the driven shaft are connected through a bearing, and the second gear is respectively meshed with the first gear and the third gear. The helical gear speed reducing mechanism is simple in structure and small in size.
Description
Technical field
The present invention relates to transmission technology field, be specifically related to a kind of helical speed reduction gear structure.
Background technique
In lathe, commonly use speed reducer, but existing speed reducer cannot realize the effect of coaxial deceleration mostly, the speed reducer that can realize coaxially deceleration arranges jack shaft outward at driving shaft and driven shaft conventionally, jack shaft respectively with driving shaft.Driven shaft is by gear transmission, and whole gearbox structure is complicated, takes up room large.
Summary of the invention
The invention is intended to provide a kind of helical speed reduction gear structure, to solve coaxial deceleration gearbox structure complexity in prior art, large problem takes up room.
Helical speed reduction gear structure in this programme, comprise frame, also comprise driving shaft, with the driven shaft of driving shaft coaxial line be located at the fixing connecting rod vertical with driven shaft between driving shaft, driven shaft, driving shaft one end is provided with the first gear, connecting rod two ends are equipped with the second gear, and connecting rod middle part is fixed with driven shaft, is fixed with the 3rd gear in frame, between the 3rd gear and driven shaft, by bearing, be connected, the second gear respectively with the first gear, the 3rd gear engagement.
Compared with prior art, advantage of the present invention is: under working state, the first gear rotates and drives the second gear to rotate, because the 3rd gear and frame are fixed, the second gear driven connecting rod rotates, and then realizes driven shaft and rotate, the present invention does not arrange jack shaft, simple in structure, volume is little, takes up room little.
Further, the first gear middle part is provided with bearing, and driven shaft one end is fixedly connected with described bearing, strengthens mechanism's stability, prevents driven shaft generation radial displacement.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is helical speed reduction gear structure embodiment's of the present invention structural representation.
Embodiment
Shown in Fig. 1, helical speed reduction gear structure in the embodiment of the present invention, comprise frame, also comprise driving shaft 1, with the driven shaft 3 of driving shaft 1 coaxial line be located at driving shaft 1, fixing connecting rod 2 vertical with driven shaft 3 between driven shaft 3, driving shaft 1 one end is provided with the first gear 11, connecting rod 2 two ends are equipped with the second gear 21, connecting rod 2 middle parts and driven shaft 3 are fixing, in frame, be fixed with the 3rd gear 31, between the 3rd gear 31 and driven shaft 3, by bearing, be connected, the second gear 21 respectively with the first gear 11, the 3rd gear 31 engagements, the first gear 11 middle parts are provided with bearing, driven shaft 3 one end are fixedly connected with described bearing.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic is not done too much description at this.Should be understood that; for a person skilled in the art, not departing under the prerequisite of structure of the present invention, can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
