Five, embodiment:
Following with reference to accompanying drawing, provide embodiment of the present utility model, be used for formation of the present utility model is further specified.
The diesel shaking-free starter of present embodiment is with reference to figure 1-6: by changing belt pulley or sprocket wheel into gear 18, increase splined shaft 24, gear 19, realize the speedup transmission, improve starting performance.By increasing clutch push rod 26, clutch opening fork 21, Returnning spring 25, postioning abutment 22, realizing quitting work fully automatically after the Starter starting, improve working life, improve Security, reduce noise.Avoid empty release by on the basis of original insurance institution, increasing safety interlock mechanism.
Transmission structures in the housing is constant, identical with existing transmission structures, comprise wind spring gear 1, unidirectional ratchet wheel 4, just around axle 6, unidirectional ratchet wheel 8, clutch gear 9, gear 10, axle 27, by gear transmission kinetic energy is delivered to the gear graduation driving mechanism;
The time movement structure is constant, comprises timing shifting block 15, timing gear 16, and timing gear 16 revolves and turns around, and the wind spring accumulation of energy is finished;
Insurance institution's structure is constant, comprise pull bar 2, release lever insurance locking plate 3, hook fork 13, reduction torsion spring 14, timing shifting block 15 on the timing gear is stirred hook fork 13, hook fork 13 and pull bar 2 interlocks, under the effect of pull bar 2 release lever being insured locking plate 3 resets, clutch gear 9 resets under the effect of extension spring and separates with gear 10, thereby realizes that Starter and diesel engine one-level break away from, and the Starter part-structure quits work;
The wind spring accumulating mechanism is the energy storage system that is made of the wind spring 17 on the spring axle, and when exempting to shake starting, wind spring 17 connects the drive diesel engine starting by the transmission device in the housing, gear graduation driving mechanism;
Adopt complete gear transmission, realize the speedup transmission by gear 18 and gear 19, make splined shaft 24 improve 2.67 times than axle 27 rotating speeds, and gear ring engagement by installing on Starter output shaft spline gear 20 and diesel engine flywheel ring gear or the hand tractor clutch, the power of 3 compressions is provided to diesel engine in the time of can guaranteeing diesel engine starting, starting and automatic energy accumulating cumulative time＜3 second, thus stopped in the using process because of belt or chain loosening, the Starter energy internal friction that factor such as skid causes is big, starting time is long or need repeatedly manually to go up spring and adjust belt or the chain belt tensioner is reset.
The gear graduation driving mechanism that increases, comprise gear 18, gear 19, spline gear 20, splined shaft 24, be used to realize the speedup transmission, improve starting performance, gear 18 and gear 19 engagements, gear 18 is installed on the axle 27, gear 19 and spline gear 20 coaxial being installed on the splined shaft 24, axle 27, rolling bearing 30 is installed at two ends respectively on the splined shaft 24, be installed on bearing support 29 and the bearing support 31 by roller bearings, bearing support 29, bearing support 31 is installed in respectively on the front and back wall of housing, the gear ring engagement of installing on spline gear 20 and diesel engine flywheel ring gear or the hand tractor clutch.
The clutch that increases comprises clutch push rod 26, clutch opening fork 21, Returnning spring 25.Clutch opening fork 21 openings one end and spline gear 20 flutings are connected, and the other end is connected with clutch push rod 26 and uses nut check.Returnning spring 25 is enclosed within the clutch push rod 26, and an end withstands on the upright arm of frame, and the other end withstands on the backing pin of clutch push rod 26.The gear ring clutch of spline gear 20 by installing on clutch push rod 26,21 realizations of clutch opening fork and diesel engine flywheel ring gear or the hand tractor clutch.
Solve the empty technical problem that causes wind spring to fracture that discharges of Starter: adopt safety interlock mechanism with release lever insure locking plate with and the spline gear fork axle of flywheel ring gear engagement on postioning abutment machinery scurry and connect together, realize safety interlock.
The safety interlock mechanism that increases comprises postioning abutment 22, safe locking plate 7, safe locking plate 23, safety interlock axle 28.Safe locking plate 7, safe locking plate 23 are installed on the safety interlock axle 28 and by several angle and are fixed together.Postioning abutment 22 is enclosed within on the clutch push rod 26.When the user is not pushed into spline gear 20 with the flywheel ring gear correct engagement by clutch push rod 26, the safe locking plate 7 of safety interlock mechanism is pressed on the release lever insurance locking plate 3 all the time, and the safe locking plate 23 of safety interlock mechanism is pressed on the postioning abutment 22 of clutch push rod 26 all the time.Safety interlock mechanism can not be the center rotation with safety interlock axle 28, and safety interlock mechanism is in locking state.At this moment release lever insurance locking plate 3 can't be opened under the effect of pull bar 2, and release lever 5 can't be depressed and discharge starting, discharges thereby avoid empty.
When the user is pushed into spline gear 20 and the flywheel ring gear correct engagement by clutch push rod 26, and when escapement clutch handle 11 is in the escapement engagement, release lever insurance locking plate 3 is opened under the effect of pull bar 2, release lever insurance locking plate 3 upwards lifts the safe locking plate 7 of safety interlock mechanism, at this moment the safe locking plate 23 of safety interlock mechanism is depressed release lever 5 and is discharged starting to falling on the clutch push rod 26.
This shows that only in spline gear 20 and flywheel ring gear correct engagement, when promptly Starter was in the on-load state, safety interlock mechanism, release lever insurance locking plate could be opened smoothly successively, Starter could normal starting.Thereby solve empty release of Starter and easily cause the technical problem that wind spring fractures or gear is beaten tooth.
Solve after the starting can not be fully and the diesel engine disengaging cause belt, sprocket wheel, chain weares and teares fast, the diesel engine noise increases, technical problem of poor safety: pass through thorn wheel change wheel drive path behind the diesel engine starting automatically to spring on the wind spring, when timing gear 16 revolves when turning around, timing shifting block 15 on the timing gear is stirred hook fork 13, hook fork 13 and pull bar 2 interlocks, under the effect of pull bar 2 release lever being insured locking plate 3 resets, clutch gear 9 resets under the effect of extension spring and separates with gear 10, thereby realize that Starter and diesel engine one-level break away from, the Starter part-structure quits work.
The safe locking plate 7 of safety interlock mechanism falls under the effect of extension spring and resets, the safe locking plate 23 of safety interlock mechanism lifts and resets, clutch push rod 26 drags the spline gear 20 disengaging flywheel ring gear that resets under the effect of reseting pressuring spring 25, thereby realizes Starter and the disengaging of diesel engine secondary.At this moment Starter separates fully with diesel engine, and Starter quits work fully.
