Description
Technical field
The invention belongs to gearbox field, and in particular to a kind of anti-off-gear structure of gearbox.
Background technology
At present, agricultural harvesting mechanical machine widely uses the gearbox of mechanical changeover, in agricultural harvesting mechanical machine operation and
Easily occur to adjust the gear finished situation out of supply during during traveling, after gearbox is out of supply, use hydraulic braking
Agricultural harvesting mechanical machine can not lean on hydraulic braking again, can only be braked by brake, and farm machinery cropper quality is larger,
So that farm machinery harvester row is difficult to brake during sailing, great potential safety hazard be present.
The content of the invention
The technical problems to be solved by the invention be just to provide it is a kind of convert gear after will not prevent gearbox out of supply automatically
Off-gear structure.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：A kind of anti-off-gear structure of gearbox, including become
Fast case and the gear level being connected on gearbox, gear level include the connecting rod being connected with gearbox and the shelves being connected on connecting rod
Bit line, finite place piece is connected on gear level, stopper slot is offered on locating part, is provided with gearbox and is passed through and prevent for gear level
The fixed seat that only gear level diametrically moves, be provided with several positioning holes in fixed seat, be provided with positioning hole with it is spacing
Groove coordinates the keeper to prevent gear level from moving in the axial direction.
Further, one end that gear line is connected with connecting rod is provided with external screw thread, and internal thread, gear line are provided with connecting rod
It is threaded connection between gearbox, locating part is stop nut, and stop nut is fixed on shelves by the external screw thread on gear line
On bit line.
Further, stopper slot is the blind hole being opened in stop nut side wall.
Further, stopper slot is the annular groove being opened in the side wall of stop nut.
Further, fixed seat includes the fixed mount being detachably connected with gearbox and has been vertically arranged several positioning holes
Anti- limited block out of supply.
Further, prevent between limited block and fixed mount out of supply being to be detachably connected.
Further, fixed mount includes the bottom plate connected with gearbox, the top plate passed through for gear line and is connected top plate
With the connecting plate of bottom plate, through hole is provided with bottom plate and top plate, gear level passes through two through holes.
Further, anti- connected between limited block and fixed mount out of supply between gearbox and fixed mount and by screw
Connect.
Further, keeper is set screw, and set screw, which is connected through a screw thread, to be fixed in positioning hole.
Further, it is provided with fastening screw nut between the head of set screw and the lateral wall of fixed seat.
Compared with prior art, the beneficial effects of the invention are as follows：
1st, after the gear of gearbox has been adjusted by gear level, observe which positioning the stopper slot on locating part is directed at
Hole, keeper is passed through into corresponding positioning hole until stopping when penetrating in stopper slot, now gear level is limited by fixed seat, is prevented
Movement radially occurs for gear level, and the inwall of locating part and stopper slot offsets, and prevents gear level from the movement on axle occurs, when
When running vibrations, the movement on axially or radially will not occur gearbox because of vibrations for gear level, firmly keep current gear,
Prevent gear situation out of supply, enhance the security of gearbox.
2nd, the internal thread connection on the external screw thread and connecting rod of existing gear line one end, by the way that stop nut is screwed into gear
On the external screw thread of the non-connecting rod of line, on the basis of existing gear level structure is not changed so that gear level has limit function, production
The machine of gear level need not re-mold, and reduce production cost, having produced the gearbox of finished product can also install on the basis of existing
The anti-off-gear structure, the scope of application are wider.
3rd, when in the blind hole that keeper penetrates in stop nut side wall, gear line can not be axially moveable, and playing prevents
The effect that gear level is axially moveable, while the cooperation of keeper and blind hole prevents stop nut from freely rotating, and ensures shelves
The stability of position.
4th, when keeper penetrates the annular groove in stop nut side wall, the side wall of keeper and the side wall of annular groove offset, and prevent
Axial movement of the locating part along gear line being only fixed on gear line, that is, prevent gear level to be axially moveable, the setting of annular groove
So that stop nut when being installed on gear line, can coordinate without inciting somebody to action because stop nut side wall one is enclosed with positioning key
Stopper slot is directed at keeper, easier for installation quick.
5th, fixed mount and gearbox are detachably connected, if parts are damaged, can individually be disassembled and be repaired more
Change, reduce maintenance cost.
6th, being detachably connected between anti-off-gear limited block and fixed mount so that anti-position of the limited block out of supply on fixed mount
Putting to be adjusted so that the cooperation of keeper and stopper slot in positioning hole is more preferable, while prevents that limited block out of supply can be independent
Disassemble and carry out maintenance replacing, reduce maintenance cost.
7th, gear level offsets through the through hole on top plate and bottom plate, i.e. through-hole side wall in the side wall and top plate of gear line,
The side wall of through hole in the side wall and bottom plate of connecting rod offsets, and two through holes prevent gear level from movement radially occurs, in gear
When fixed, moving radially so that keeper departs from from stopper slot because of gear level is prevented so that gear can be fixedly secured,
During installation, the top plate and bottom plate of gear level through fixed mount need to be only fixed to fixed mount again, pass through simple two
Individual through-hole structure realizes the fixation of gear level, reduces production cost.
8th, mode connects for screw cause connection between gearbox and fixed mount and it is anti-between limited block and fixed mount out of supply
While being connected firmly, simple and fast is mounted and dismounted, reduces the installation and removal time, improves production and maintenance efficiency.
9th, it is threaded into positioning hole and passes through for threaded connection, set screw between set screw and positioning hole and determines
Position hole is finally inserted into stopper slot, swift and convenient to operate, reduces the gear set time.
10th, by setting fastening screw nut between limited screw and positioning hole, prevent set screw from occurring in positioning hole
Loosen and exit positioning hole.
Compared with prior art, the present invention is prevented by the cooperation of locating part and the keeper of fixed seat on gear level
Movement on axle occurs for gear level, and when gearbox is running vibrations, the movement of axial direction, jail will not occur because of vibrations for gear level
Admittedly keeping current gear, that is, prevent gear situation out of supply, enhance the security of gearbox.
