Abstract
The utility model discloses two jack shaft two-speed gearbox, its housing rear end is provided with motor, and motor front end is provided with internal spline motor shaft coupling and stretches in housing, and internal spline motor shaft coupling front end is connected with main shaft, main shaft second gear is connected with main shaft by sliding sleeve, and main shaft is provided with output flange foremost; Main shaft both sides are provided with jack shaft, and jack shaft first gear is connected with main shaft first gear, and jack shaft second gear is connected with main shaft second gear, and jack shaft the 3rd gear is connected with main shaft the 3rd gear.The utility model gear shift is convenient, noise is little, cost is low.
Description
Technical field
The utility model relates to power transmission and output mechanism, is specifically related to two jack shaft two-speed gearbox.
Background technique
Existing two-speed gearbox, its high pulling torque speed reducer gear used and the equal diameter of axle are large, and gearshift is heavy, and manufacture cost remains high; Former speed reducer adopts single jack shaft, two-stage transmission, shifting slide gear speed change, is a kind of conventional speed reducer structure, and volume is heavy, and cost is high, and noise is comparatively large, easy clamping stagnation of shifting gears.
Model utility content
The purpose of this utility model is the shortcoming and defect in order to overcome prior art, provides two jack shaft two-speed gearboxs that gear shift is convenient, noise is little, cost is low.
Two jack shaft two-speed gearbox, comprises housing, motor, internal spline motor shaft coupling, bearing, main shaft, main shaft first gear, main shaft second gear, main shaft the 3rd gear, output flange, sliding sleeve, jack shaft, jack shaft first gear, jack shaft second gear, jack shaft the 3rd gear;
Described housing rear end is provided with motor, motor front end is provided with internal spline motor shaft coupling and stretches in housing, described internal spline motor shaft coupling front end is connected with main shaft, the two ends of main shaft are provided with bearing, main shaft first gear, main shaft second gear, main shaft the 3rd gear is provided with successively before and after on described main shaft, described main shaft second gear is connected with main shaft by sliding sleeve, and described main shaft is provided with output flange foremost;
Described main shaft both sides are provided with jack shaft, described jack shaft two ends are provided with bearing, jack shaft first gear, jack shaft second gear, jack shaft the 3rd gear is provided with successively before and after jack shaft two ends, described jack shaft first gear is connected with main shaft first gear, jack shaft second gear is connected with main shaft second gear, and jack shaft the 3rd gear is connected with main shaft the 3rd gear.
The beneficial effects of the utility model are, adopt two jack shaft scheme, the moment of torsion of main shaft transmission is jointly shared with two jack shafts, because the gears meshing stress balance of main shaft, so main shaft only bears moment of torsion, do not produce moment of flexure, moreover the moment of torsion of single gear tooth transmission on jack shaft is reduced to original half, mainshaft gear two teeth are simultaneously stressed, and gears all like this and axle all can reduce diameter greatly;
Another advantage is that gearshift is convenient, and the gear that main shaft is installed rotates at the effect low suspension of two jack shafts, is convenient to adopt internal messing tooth cover engage a gear, and engaging sleeve gearshift is much lighter than gear slippage gearshift.
