Description
Technical field
The utility model relates to gas starter technical field, is a kind of gas starter power take-off mechanism specifically, and this power take-off mechanism can combine with multi-form gas starting motor, is specially adapted to diesel engine gas start-up system.
Background technique:
The diesel engine of power in 80HP ~ 4000HP scope extensively adopts the gas starter to start, and elasticity of demand is made a concession when the output gear of gas starter and the engagement of diesel engine flywheel ring gear, otherwise when two teeth offset, can't accurately mesh.For realizing accurate engagement, usually output gear and output shaft are designed to split-type structural, and because the installing space restriction, split-type structural must cause intensity, rigidity and the output gear wheel hub safety coefficient of output shaft to reduce.Because it is gas starter output gear and diesel engine flywheel ring gear velocity ratio are big, and moment of torsion is big, very high simultaneously to the structural rigidity requirement of gas starter power output.The common problem that this traditional gas starter power take-off mechanism exists is: it is high that bent output shaft damages rate of fault, and output gear broken teeth rate of fault is high.
Summary of the invention:
The purpose of the utility model is the deficiency that overcomes above-mentioned prior art, and provides a kind of gas to start power take-off mechanism, mainly solves existing gas starter power take-off mechanism bent output shaft and damages problems such as rate of fault height and output gear broken teeth rate of fault height.
The technological scheme of the utility model is: a kind of gas starts power take-off mechanism, and its special way is that it comprises jack shaft and output gear shaft, and through the shaft block ring connection bearing, bearing connects piston through the hole with back-up ring to jack shaft outward; On output gear shaft, establish external splines, establish internal spline on the passive gear wheel, external splines connects in the two; On the cylindrical of passive gear wheel, establish clutch spring, on output gear shaft, establish spring shield, spring shield is positioned at outside the clutch spring; Screw and packing ring are fixed on output gear shaft on the jack shaft; Passive gear wheel is corresponding with jack shaft, and jack shaft drives passive gear wheel rotation, and passive gear wheel drives the output gear shaft rotation; Piston peripheral hardware cylinder block is established Returnning spring between piston and the cylinder block, and remaining part move left and right in cylinder block moves right the compression piece Returnning spring except that Returnning spring, and the movement parts Returnning spring discharges compression left.
Compared with present technology a kind of gas startup power take-off mechanism of the utility model has following good effect and is: the output gear and the output shaft split-type structural that change traditional gas starter; Be designed to integral gear axle construction; Power input end at output gear shaft is designed with non-self-locking helical spline; When the gear of output gear shaft and diesel engine flywheel have two teeth to offset; Output gear shaft rotates to an angle under the effect of non-self-locking helical spline automatically, accurately meshes up to two teeth, guarantees accurate engagement; Adopt this monolithic construction, intensity, the rigidity of axle and output gear all are improved, and have solved traditional gas starter bending shaft and the high problem of output gear broken teeth rate of fault.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
In order to understand better and to implement, provide specific embodiment below in conjunction with accompanying drawing and specify the utility model.
Embodiment 1; Referring to Fig. 1, be processed into jack shaft 7 and output gear shaft 1, jack shaft 7 is outer through shaft block ring 10 connection bearings 11; Bearing 11 connects piston 5 through the hole with back-up ring 4, and promptly piston 5, jack shaft 7, bearing 11 connect with back-up ring 4, shaft block ring 10 through the hole; On output gear shaft 1, process external splines, process internal spline on the passive gear wheel 12, external splines connects in the two; Clutch spring 3 is installed on the cylindrical of passive gear wheel 12, and fixing spring cover 2 on output gear shaft 1, spring shield 2 are positioned at outside the clutch spring 3; With screw 8 and packing ring 9 output gear shaft 1 is fixed on the jack shaft 7; Passive gear wheel 12 is corresponding with jack shaft 7, and jack shaft 7 drives passive gear wheel 12 rotations, and passive gear wheel 12 drives output gear shaft 1 rotation; Cylinder block 6 is installed outside piston 5, Returnning spring 13 is installed between piston 5 and the cylinder block 6,, move right compression reseting spring 13, discharge compression to left movement Returnning spring 13 except that Returnning spring 13 all components move left and right in cylinder block 6.
The described a kind of gas of the utility model starts power take-off mechanism; Its working principle is: under pressurized air promotes; Except that cylinder block, all component integral body of gas starter power take-off mechanism move right, and the gear on the output gear shaft of power take-off mechanism is meshed with the diesel engine flywheel ring gear; As have that two teeth offset when meshing, when output gear shaft can't continue to move right; Continue to move right under pressurized air promotes with back-up ring, piston, jack shaft, shaft block ring, bearing, passive gear wheel etc. in the hole, the relative output gear axial screw of the internal helix spline of passive gear wheel external splines moves right, and drives output gear shaft and along the circumferential direction rotate to an angle; Can eliminate two teeth and offset, make two tooth correct engagement.After gear engagement puts in place, begin to drive diesel engine starting.After diesel engine starting was accomplished, the short time flywheel ring gear drove the output gear shaft high speed rotating, and free wheel device skids between passive gear wheel and the jack shaft at this moment, avoids output gear shaft high speed rotary motion to be imported into component such as starting motor.Meanwhile whole power take-off mechanism resets under action of reset spring, and the gear of output gear shaft and flywheel ring gear break away from engagement, the complete end of diesel engine starting process.
