Description
Technical field
The utility model belongs to Engineering Machinery Components manufacturing technology field, particularly a kind of flexible shaft controller gear-box.
Background technique
The shifted operating mechanism of current construction machinery industry adopts flexible shaft controller mostly, its core component is flexible shaft controller gear-box, " the engineering machinery gear change structure " of notification number CN201963855U is a kind of typical structure wherein, the annexation of straight-tooth wheel shaft and housing is described in the document [0013] section, be specially: on straight-tooth wheel shaft, silk braid is set, silk braid is fixed on housing by screw thread, and by nut by silk braid and the fastening one of gear shaft, by regulating adjustable silk braid, upper-lower position on straight-tooth wheel shaft regulates the meshing problem of driving bevel gear and spur gear shaft assembly, this annexation have employed threaded adjusting structure to adjust umbrella gear back lash, and its Shortcomings part is:
1, adopt threaded adjusting structure, due to the existence of thread pitch, because of the gap fluctuations that the uncertainty of adjustment causes gear pair to engage when causing assembling, affect the stationarity of transmission.
2, silk braid, screw thread and the annexation relative complex with straight-tooth wheel shaft, add machining man-hour, equipment adjustment workload, therefore cost is higher.
Summary of the invention
The utility model is the deficiency for avoiding existing for above-mentioned prior art, a kind of flexible shaft controller gear-box is provided, object is the improvement by structural design, namely adopts axle reliably to locate with hole the gap fluctuations regulating with pad to avoid gear pair to engage, reduces manufacture cost simultaneously.
The technical problem that the utility model solves realizes by the following technical solutions:
The structural feature of the utility model flexible shaft controller gear-box is: described flexible shaft controller gear-box is provided with back shaft in gear box casing, half spur gear and driven half bevel gear are arranged on the two ends of connecting sleeve respectively, oil-impregnated bearing is respectively arranged with at the two ends of the endoporus of described connecting sleeve, an assembly parts is assembled into by half spur gear, driven half bevel gear, connecting sleeve and oil-impregnated bearing, described assembly parts is arranged on back shaft, and the endoporus of oil-impregnated bearing coordinates for dynamic with the periphery of back shaft; By socket head screw and pressure pad initiatively half bevel gear and initiatively half bevel gear shaft be fixed together and form active half cone gear assemblies; Described active half bevel gear shaft is contained in the bore of gear box casing, and described active half bevel gear is meshed with driven half bevel gear; Between described active half bevel gear and the contact end face of gear box casing, adjustment pad is installed, lining is provided with between described active half bevel gear shaft and gear box casing bore, the periphery of described lining and the bore of gear box casing are interference fit, and described active half bevel gear shaft coordinates for dynamic with the endoporus of lining; Described active half bevel gear shaft is equipped with pad and circlip for shaft to limit the axial position of described active half bevel gear shaft on gear box casing.
The utility model flexible shaft controller gear-box, its feature is also: in the termination groove of described back shaft, arrange circlip, makes back shaft obtain axial limiting.
Compared with existing technology, the utility model beneficial effect is embodied in:
1, the utility model adopts axle and hole is reliably located and pad regulates and carrys out alternative threaded adjusting structure, effectively prevent the gap fluctuations of gear pair engagement, adds the secondary stationarity engaged of gearbox drive.
2, the utility model structure is simple, reduces the machining man-hour of component, removes equipment adjustment man-hour from, reduce manufacturing cost 10%-15%.
