Description
Technical field
The utility model belongs to tractor field, relates to a kind of tractor and advances and to fall back reciprocating reversing driving mechanism.
Background technique
At present, the rearmounted reversing transmission mechanism of domestic existing wheeled tractor is mostly arranged between gearbox and back axle, and the front support of its driving component is on gearbox, and rear end is supported on back axle, adopts axle to take axle arrangement.Because two tanks is processed respectively, after two casees mould assembling, the coaxiality deviation of two tanks transmission axis hole is comparatively large, and add the machining deviation of two casees axial workpieces, between transmission shaft, coaxality Accumulated deviation is comparatively large, needs driving component to be out of shape and makes up Accumulated deviation.Driving component bears very large additional load, and rate of fault is higher, causes whole aircraft reliability poor.Although improve machining accuracy can reduce rate of fault, be both limited to existing equipment, technology and quality level of control, turn increased cost, in production in enormous quantities, be difficult to thorough solution.For this reason, develop a kind of tractor and advance and to fall back reciprocating reversing driving mechanism, the welcome of user will be subject to.
Model utility content
The purpose of this utility model is to provide a kind of simple for structure, easy processing, the tractor that easy to assembly, reliability is high advances the reciprocating reversing driving mechanism that falls back.
The utility model can be achieved through the following technical solutions above-mentioned purpose: a kind of tractor advances the reciprocating reversing driving mechanism that falls back, and comprising: rear axle housing body, detachable dividing plate, bearing support, adjustment pad, input gear, output shaft of gear-box, duplicate gear, idler shaft, screw, idle pulley, stop collar, small coning gear shaft, setting sleeve, reverse output gear, engagement toothholder, engaging sleeve, detachable dividing plate is passed through locating stud, be bolted in rear axle housing body, bearing support and adjustment pad fastening piece are fixed on detachable dividing plate, input gear passes through bearing positioning supports on bearing support, output shaft of gear-box and input gear spline joint, duplicate gear front end and back end respectively by bearings on detachable dividing plate and rear axle housing body, idler shaft insert rear axle housing body hole in and be screwed, idle pulley to be located with stop collar on idler shaft by bearings, small coning gear shaft by bearings on rear axle housing body and input gear, setting sleeve is sleeved on small coning gear shaft, reverse output gear by bearing assemble on small coning gear shaft, engagement toothholder and small coning gear shaft spline joint, engaging sleeve with engage toothholder spline joint.
The utility model can reach following good effect after adopting technique scheme: detachable dividing plate is fixed in rear axle housing body, a separate space is formed in rear axle housing body front portion, driving component is assemblied in the anterior separate space of rear axle housing body, the advance reciprocating reversing driving mechanism that falls back of tractor establishes one's own system, and shares rear axle housing body with other component in back axle.Therefore, this tractor advance fall back that reciprocating reversing driving mechanism is simple for structure, easy processing, easy to assembly, reliability is high, has higher use value.
Accompanying drawing explanation
Fig. 1 is that a kind of tractor of the utility model advances the structural representation of reciprocating reversing driving mechanism of falling back.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.The present embodiment as shown in Figure 1, a kind of tractor advances the reciprocating reversing driving mechanism that falls back, and comprising: rear axle housing body 1, detachable dividing plate 2, bearing support 3, adjustment pad 4, input gear 5, output shaft of gear-box 6, duplicate gear 7, idler shaft 8, screw 9, idle pulley 10, stop collar 11, small coning gear shaft 12, setting sleeve 13, reverse output gear 14, engagement toothholder 15, engaging sleeve 16.Detachable dividing plate 2 is passed through locating stud, bolts etc. are fixed in rear axle housing body 1, bearing support 3 and adjustment pad 4 fastening piece are fixed on detachable dividing plate 2, input gear 5 by positioning supports such as bearings on bearing support 3, output shaft of gear-box 6 and input gear 5 spline joint, duplicate gear 7 front end and back end to be supported on idler shaft 8 by bearing etc. at idle pulley 10 respectively by bearings and to locate with stop collar 11, small coning gear shaft 12 is supported on rear axle housing body 1 and input gear 5 by bearing etc., setting sleeve 13 is sleeved on small coning gear shaft 12, reverse output gear 14 is assemblied on small coning gear shaft 12 by bearing etc., engagement toothholder 15 and small coning gear shaft 12 spline joint, engaging sleeve 16 with engage toothholder 15 spline joint.
During forward gears work, engaging sleeve 16 moves forward, and mount with input gear 5 spline, power is delivered to input gear 5 by output shaft of gear-box 6, then is delivered to small coning gear shaft 12 through engaging sleeve 16, engagement toothholder 15 successively, thus makes tractor obtain onward impulse.
During backward gear work, engaging sleeve 16 moves backward, mount with reverse output gear 14 spline, power is delivered to input gear 5 by output shaft of gear-box 6, reverse output gear 14 is passed to successively via intermeshing duplicate gear 7, idle pulley 10, be delivered to small coning gear shaft 12 through engaging sleeve 16, engagement toothholder 15 successively again, thus make tractor obtain the power that falls back.
In the utility model, the advance reciprocating reversing driving mechanism that falls back of tractor establishes one's own system, and shares rear axle housing body with other component in back axle.Therefore, the advance of this tractor falls back, and reciprocating reversing driving mechanism is simple for structure, easy to assembly, reliability is high, has higher use value.
