Miniature farm machinery gearbox function is generally following 3 points: one, change gearratio; Two,, in the constant situation of hand engine rotation, machine can be fallen back and travel; Three, utilize neutral, interrupt power transmission, so that engine can start, idling, and be convenient to shifting of transmission or carry out power output. The reverse gear of prior art miniature farm machinery gearbox is to have increased in addition by place's reverse gear mechanism in casing outside, forms the transmission system of reversing gear. Prior art miniature farm machinery gearbox is mainly made up of gear and axle, comprise casing, main shaft, active duplex-gear (little tooth), active duplex-gear (canine tooth), countershaft duplex-gear (canine tooth), countershaft duplex-gear (little tooth), countershaft driving tooth, the duplex-gear that reverses gear (canine tooth), the duplex-gear that reverses gear (little tooth), gearshift shifting block, gear shift arm and selector fork axle, produce variable-speed torque-converting by different gear combination, realize reverse gear. Due to this reverse gear transmission system and the transmission system of advancing, parallel also referred to as work transmission system, therefore, in the time advancing the running of (work) transmission system, also can hang up reverse gear simultaneously, therefore, easily cause gear or casing to damage. On the other hand, in the time of operation, prior art miniature farm machinery gearbox, in the time of reverse gear, is to be strained and realized reverse gear by zip, and personnel operate effort. And, prior art operating mechanism complexity, very easily maloperation.
Generally speaking, the miniature farm machinery gearbox of prior art exists gear or casing to damage, reverse gear is to strain by zip reverse gear operation effort, the existing very easily problem of maloperation of operating mechanism complexity of realizing now.
Summary of the invention
Damage for solving gear or the casing that prior art all-gear drive gearbox exists, reverse gear is strain and realized reverse gear operation effort, the existing very easily problem such as maloperation of operating mechanism complexity by zip now, the utility model proposes a kind of all-gear drive gearbox.
The utility model all-gear drive gearbox, comprise casing, main shaft, initiatively duplex-gear (little tooth), initiatively duplex-gear (canine tooth), countershaft duplex-gear (canine tooth), countershaft duplex-gear (little tooth), lining reverses gear, countershaft driving tooth, duplex-gear (canine tooth) reverses gear, duplex-gear (little tooth) reverses gear, gearshift shifting block, gear shift arm and selector fork axle, described active duplex-gear (little tooth), initiatively duplex-gear (canine tooth), countershaft duplex-gear (canine tooth), countershaft duplex-gear (little tooth), lining reverses gear, countershaft driving tooth, duplex-gear (canine tooth) reverses gear, duplex-gear (little tooth) reverses gear, gearshift shifting block, gear shift arm and selector fork axle are arranged in casing, and be positioned on main shaft, described active duplex-gear (little tooth) is meshing with countershaft duplex-gear (canine tooth) is forward gear, described gear shift arm, selector fork axle, shifting block can stir active duplex-gear (canine tooth) and active duplex-gear (little tooth) slides and realizes transforming gear on main shaft.
The beneficial effect of the utility model all-gear drive gearbox is: can make more easily study of work, reduce labour intensity obvious, increase equipment operating security, reduce reverse gear zip, a whole set of mechanism of reverse gear handgrip, thereby reduced production costs.
