Background technique:
In the machine power driving mechanism, the shifting of transmission transmission is the common kind of drive.Existing transmission shift fork adopts the mechanical mode of stirring mostly.Mechanical type multidigit gearshift, the structure more complicated, and when having operating cost in the using process, big, the gear shift of effort, noise whether put in place bad judgement, problem such as trip stop easily.Especially in the high-power speed changer of the on-the-spot machinery of petroleum drilling and mining, the ubiquity hand shift is not easy to hang and closes, thereby and the vibration of equipment cause problem out of supply too greatly easily.
Along with the development of hydraulic pressure and pneumatics, the performance of various Pneumatic valves, cylinder, air compressor and reliability have reached very high level, and low price, have all obtained using widely in every field.Pressurized air is as a kind of desirable working medium, during the necessary gear shift that applies it to the on-the-spot mechanical high-power speed changer of petroleum drilling and mining is controlled, to satisfy the demand of oil development technical development.
Summary of the invention:
In order to overcome the deficiency of existing technology, the object of the present invention is to provide a kind of slide unit cylinder type multidigit shift fork gearshift, have simple in structure, be quick on the draw, pneumatic control, characteristics that functional reliability is high.
The present invention realizes above-mentioned purpose through following technological scheme.
In the structure of slide unit cylinder type multidigit shift fork gearshift, be provided with housing, last slide unit cylinder, cylinder connecting plate, following slide unit cylinder, semicircle shift fork, gear shift gear ring, left gear, middle gear, right gear, central shaft; Last slide unit cylinder is fixedly mounted on the housing; Last slide unit cylinder is installed together through cylinder connecting plate and screw, straight pin with following slide unit cylinder; Semicircle shift fork is installed in down the bottom of slide unit cylinder; The outer of gear shift gear ring is designed with groove, and the shift fork on the semicircle shift fork is stuck in the groove of gear shift gear ring; Middle gear is through the outer ring of key connecting sleeve at central shaft; The gear shift gear ring is enclosed within the outer ring of middle gear, and the internal gear of gear shift gear ring and the external gear of middle gear are connected through gear; Left gear and right gear are positioned at the both sides of middle gear, and when the gear shift gear ring slided on left gear or the right gear, the external gear of the internal gear of gear shift gear ring and left gear or right gear was connected through gear.
The present invention has following beneficial effect compared with prior art:
1, slide unit cylinder type multidigit shift fork gearshift simple in structure, be quick on the draw, easy to operate simple and direct, the quality and time of having improved gear shift; Through adopting compressed-air shifting, help realizing complicated gearshift logic control.
2, device is independent of the machine driven system of speed changer, makes to install and the maintenance modularization that becomes, and when raising the efficiency, has also improved the reliability of equipment.
