Description
Technical field
The present invention relates to a kind of farm machinery decelerator, more particularly to a kind of novel agricultural ploughing machine decelerator.
Background technology
Existing agricultural ploughing machine decelerator many employings epicyclic transmission mechanism, cost is high. And in order to ensure the sun gear life-span of planetary mechanism, the gear ratio of epicyclic transmission mechanism is unsuitable excessive, and the undersized of sun gear otherwise will be made to reduce the life-span of whole decelerator, and little gear ratio makes output moment of torsion diminish, and namely arable land power is little. Agricultural ploughing machine inevitably has the situation that reversing retreats in the process used, and agricultural ploughing machine decelerator reverses gear all without setting, can only dragging artificially realize retreating. Because output shaft is constantly in the state being connected with power shaft, the process of dragging must be to drag whole reducing gear so that it is all pinion rotation, is substantially the process of a speedup, and this allows for dragging agricultural ploughing machine and retreats gruelling.
Summary of the invention
A kind of novel agricultural ploughing machine decelerator that the present invention proposes adopts the structure of parallel axes, reduces the cost of decelerator, and increases gear ratio, makes output moment of torsion become big, ploughs more laborsaving; Output shaft adds the disengagement structure with output gear, is no longer drag whole deceleration system when needs artificially drag and retreat or advance, makes dragging more laborsaving; Adopt symmetrical structure to achieve power dividing, under equal volume, improve bearing capacity.
For this, the present invention is achieved through the following technical solutions.
A kind of novel agricultural ploughing machine decelerator, it is characterised in that: include input connecting plate 1, driven gear shaft I 2, input gear wheel I 3, input gear axle 4, output gear 5, a block 6, outfan connecting plate 7, general flat key 8, spline housing 9, shift fork 10, eccentric 11 and output shaft 12.

Further, described shift fork (10) is fixed on the periphery of spline housing (9), and spline housing (9) can be driven to horizontally slip on output shaft (12).
The invention have the advantages that and good effect:
(1) adopting parallel-axis type drive mechanism, it is to avoid the processing of ring gear, more existing epicyclic transmission mechanism cost reduces.
(2) parallel-axis type drive mechanism gear ratio is not by the restriction of sun gear, can be increased by gear ratio, make output moment of torsion increase, plough more laborsaving, and adopt symmetrical structure, it is achieved power dividing, under equal volume, bearing capacity is increased.
(3) eccentric wheel structure is adopted to drive spline housing to horizontally slip on output shaft, it is achieved the power interruption of output shaft and reducing gear, it is achieved artificial dragging agricultural ploughing machine is more laborsaving when retreating or advance; And eccentric rotary motion is changed into the rectilinear motion of shift fork, control simple effectively.
