Description
Technical field
The present invention relates to a kind of farm machinery, particularly a kind of transmission mechanism that is used for Miniature cultivator used on higher.
Background technology
The gear shift mode of existing minitype tiller gearbox is: input shaft rotational speed is slowed down successively step by step by the plurality of teeth wheel set earlier, driving shaft of transmission running gear then and power take-off.The defective of this gear shift mode is: 1, deceleration path length, cause the gear-box volume bigger; 2, deceleration path length, slowing-down structure complexity step by step, power attenuation is big; 3, since rotating speed before finally passing to running gear driving shaft and power take-off, through slowing down step by step, so the tooth factor that the power output of power output gear can be subjected to formerly slowing down makes the power of supporting farm machinery be restricted than restriction.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of compact conformation, power consumption is little, speed changing structure is reasonable in design minitype tiller gearbox are provided.
Technical solution of the present invention is: minitype tiller gearbox, and it comprises casing, be erected at the axle on the casing and be arranged on gear on the axle; It is characterized in that: the axle that is erected on the casing comprises a power shaft, a power take-off, a stub and two propel driving shafts; Wherein power shaft stretches into the interior partial fixing of casing main driven wheel, and is provided with slippage speed change duplicate gear, and slippage speed change duplicate gear is provided with shift fork; Be fixed with main driven gear and power output gear on the power take-off, on the axle between main driven gear and the power output gear, be set with reverse dual-linked gear; The stub middle part is fixed with duplex connector gear, is socketed with a connector gear on the stub of the duplex connector gear left and right sides respectively, and the stub in the connector gear outside is provided with holddown spring, and the connector gear is provided with shift fork; Propel driving shaft stretches on the box house branch and is fixed with the walking driven wheel; Main driven wheel and main driven gear often mesh; Slippage speed change duplicate gear has four slippage gears, advance one grade is that the pinion of slippage speed change duplicate gear and the gear wheel of duplex connector gear mesh, the second gear that advances is the pinion of the gear wheel and the duplex connector gear of slippage speed change duplicate gear, neutral gear is the big of slippage speed change duplicate gear, pinion all not with any gears engaged, reverse gear is the gear wheel engagement of the gear wheel and the reverse dual-linked gear of slippage speed change duplicate gear, the gear wheel of the pinion of reverse dual-linked gear and duplex connector gear often meshes, and the connector gear often meshes with the walking driven wheel; The connector gear under the holddown spring effect with duplex connector gear engagement, under the shift fork effect, separate with duplex connector gear.Described normal engagement is meant a kind of connected mode that under any circumstance all is in engagement.
Advantage of the present invention is: 1, driving force directly is distributed into power output and is driven two branch roads that are independent of each other of walking by power shaft input back, has shortened the deceleration path, has reduced the gear-box volume; 2, because the deceleration path contraction, speed changing structure is oversimplified, so power attenuation has reduced; 3, because driving force directly is distributed into power output and two branch roads that are independent of each other of driving walking by power shaft input back, therefore the power output of propel driving shaft and the power output of power take-off are independent of each other mutually, can satisfy the power demand of running gear fully, can satisfy the farm machinery requirement fully again, make speed changing structure more become reasonable.
