Detailed description of the invention
For making those skilled in the art be better understood from technical scheme, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1-Fig. 3 is the front view of embodiment middle gear running in machine, left view and top view respectively.It is seen that the predominantly organic body 1 of running-in of gear device, power part 2, driving shaft 3, driven shaft 4, fuel tank 5, supporting plate 6 and handwheel 7 form.Wherein power part 2, driving shaft 3, driven shaft 4, supporting plate 6 are installed on the fuselage 1, and bearing spider is provided with bearings driving shaft 3, driven shaft 4, and meets certain lubricating requirement, reduce the frictional force with fuselage 1 bearing spider when rotating.In the present embodiment, power part 2 is motor, and its outfan is equipped with belt pulley, and driving shaft 3 is also provided with belt pulley, and the belt that rotates through of motor is delivered to driving shaft 3；Electromotor velocity is adjustable, meets different rotating speeds demand.
In the present embodiment, driving shaft 3 has the first axle head, and driven shaft 4 has the second axle head.Owing to illustrating the first axle head, the second axle head all in fuel tank 5, it is impossible to find out.Needing the gear mesh that running-in is tested to be arranged on the first axle head, the second axial end by axle head screw, driving shaft 3 is rotated and is transferred to driven shaft 4 by the gear teeth meshing of gear mesh.
In the present embodiment, fuel tank 5 is made up of casing 51, case lid 52, and casing 51 and case lid 52 are removably tightly connected.Casing 51 has the sealing that can be inserted into the first axle head and the second axle head and inserts hole and oil filler point 53.Seal to insert in hole and there is bearing, the first axle head, the second axle head can be reduced and seal the friction inserting hole；Additionally, seal insertion hole there is sealing ring, it is prevented that fuel tank seals after injecting lubricating oil and inserts the leakage of oil of hole place.Casing 51 is additionally provided with fuel feed hole 53, conveniently adds lubricating oil.
During work, first casing 51 it is socketed on the first axle head and the second axle head and gear mesh is installed, subsequently case lid 52 being arranged on casing 51, reach certain sealing property, then inject lubricating oil to fuel tank 5 and start power part 1 and just can start to test running-in.In casing 51, two sealing insertion pitchs of holes set according to the reference center distance of testing gears pair, therefore ensure that the installation of gear mesh is correct without measuring.The speed of power part 2 is adjustable, therefore can from low speed to progressively adjusting at a high speed, the testing gears noise situations to nibbling generation, it is judged that whether gear mesh is qualified；Or regulate running-in speed, successive elimination mismatch error from low speed to high speed.Adopting lubrication and the heat transfer cooling effect of lubricating oil, gear mesh high speed running-in for a long time can eliminate the error of generation in processing and the mismatch error of gear.
It is pointed out that driving shaft 3 in the present embodiment, driven shaft 4 are and are horizontally disposed with, for grafting the first axle head and the second axle head the installation facilitating gear mesh, fuel tank is divided into casing 51 and case lid 52 two parts, and offers sealing at casing 51 and insert hole；Driving shaft 3, driven shaft 4 also by being set to other angles, such as vertical angles, now then can not adopt case lid 52 and seal and insert hole.
In the present embodiment, driven shaft 4 installs the slave unit providing load, and slave unit provides load to make run with load in gear mesh simulation actual motion, and the gear of test run with load coordinates noise situations；As needed running-in to eliminate error, run with load can reduce gear mesh and reach the seating time of reasonable noise.Slave unit in the present embodiment includes screw rod, spring and friction pulley and friction plate, spring housing is connected on screw rod, spring one end is provided with friction pulley, under the compression of screw rod, spring can be taken turns and the friction plate friction being arranged on driven shaft by pressing friction, is simulated the run with load of driven shaft by rubbing action.Screw rod rotates the compression situation of adjustable springs, changes the frictional force size of friction pulley and friction plate, regulating load size.In other embodiments, it is possible to adopt other load to provide parts, such as the form offered load of other driven members external；Or be not provided with providing parts, simply unloaded running-in.
In the present embodiment, driven shaft 4 being provided with slide plate, supporting plate 6 has screw mandrel, the rotary motion of screw mandrel can be converted into the displacement movement of slide plate.Being provided with handwheel 7 on screw mandrel, handwheel 7 drives screw mandrel to rotate and makes supporting plate drive driven shaft 4 to move, can change the axle base of driven shaft 4 and driving shaft 3, test various sizes of gear mesh.In other embodiments, it is possible to mobile driving shaft 3 adjusts axle base.Certainly, it is possible to adopt commonly used in the art other to move parts and realize distance between axles adjustment.
The present embodiment has manufactured and designed multiple fuel tank 5, all have two to seal insertion hole in each fuel tank 5, the insertion hole that seals of each fuel tank 5 sets different centre-to-centre spacing according to national standard, adjustable in conjunction with the distance between axles between driving shaft 3 and driven shaft 4, test the various sizes of gear mesh of running-in.Because sealing the distance inserting hole all according to standard setting, various gear mesh all just can correctly coordinate installation without measuring.Certainly, it is possible in same fuel tank, arrange multiple sealing insert hole, multiple sealings are inserted hole combination of two and are formed various criterion centre-to-centre spacing, and adopt the sealing that seal member sealing does not use to insert hole.
In the present embodiment, gear mesh noise in test process is relatively big, can add abrasive media in lubricating oil, eliminates error by the effect of abrasive media in running-in, because tank lubrication oil and running-in machine spindle lubricating system are independent, axis system will not be damaged by abrasive media.After running-in completes, after taking off gear mesh, the superficial appearance of hand inspection gear mesh refills case delivery, it is ensured that product quality.
Drain the oil for convenience, change the lubricating oil comprising different model abrasive media, it is possible to oil outlet is set bottom casing 5, connect external pipeline release lubricating oil by oil outlet, it is prevented that the pollution of work place.
Running-in of gear device in the above embodiment of the present invention is described in detail.Apply specific case herein principles of the invention and embodiment are set forth; the explanation of above example is only intended to help to understand the core concept of the present invention; without departing from the principles of the present invention; the present invention also can carry out some improvement and modification, and these improve and modification also falls in protection scope of the present invention.
