Described clutch is the slip clutch of hydraulic control, and it comprises one built with the clutch outer member of piston, intermeshing outside friction disc and inner attrition piece, and the internal tooth of inner attrition piece is meshed with driving gear first line of a couplet all-in-one-piece clutch base; Piston and return spring are close together on power shaft simultaneously; One end of described Pulley shaft is connected with an oil pump, and described oil pump to be connected with clutch application valve by oil circuit and when operation of oil pump, hydraulic oil to be sent into clutch application valve; The other end of Pulley shaft is equipped with belt pulley, and is exported by belt.
The utility model is according to the market demand, improvement on the basis of existing technology, and it is by having filled a set of hydraulic clutch on existing reduction gear box, the control valve action on hydraulic clutch, after clutch, determines whether output shaft rotates.And a driving bevel gear often turned is housed on power shaft, Pulley shaft is equipped with a driven bevel pinion be meshed, and the other end being carried out power by the belt pulley on Pulley shaft and Pulley shaft is exported; Reach dual output and right angle output simultaneously, utilize hydraulic clutch, the efficient combination of Cylindrical gears and bevel gear, reach required operating mode, increase economic efficiency.
The utility model completes and by a diesel engine, power is inputted (prime mover), makes one to input drive two output; Namely belt pulley is exported and is exported by clutch.Belt pulley exports and turns for normal, by clutch export by control valve maneuvering and control; When needing power stage, rotate control valve control crank, clutch is combined, output shaft rotation.
The utility model efficiently solves the requirement that a machine two exports, and utilizes the engagement of clutch and gear, controllable parallel output simultaneously; Use the engagement of bevel gear, carry out 90 degree of right angles and export; There is structure simple, easy to install and use, the features such as good reliability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, this utility model is described in detail: shown in Fig. 1,2, the reduction gear box of a kind of grain header described in the utility model, it mainly comprises a casing 10, be arranged on the power shaft 1 in casing, this power shaft 1 is provided with a clutch and is connected the driving gear 6 of a kink on power shaft 1 by this clutch, this driving gear 6 and one is fixedly mounted on driven gear 13 on output shaft and is meshed; Described power shaft 1 is also installed with a driving bevel gear 9, this driving bevel gear 9 engages with the driven bevel pinion 22 be fixedly mounted on Pulley shaft 23; Described power shaft 1 and Pulley shaft 23 are bearing in casing respectively by respective bearing, and power shaft 1 and Pulley shaft 23 are in being mutually arranged vertically, and namely Pulley shaft 23 has two bearings to be bearing on casing 10, exports with power shaft 1 one-tenth horizontal 90-degree.
Shown in figure, described clutch is the slip clutch of hydraulic control, it comprises one built with the clutch outer member 4 of piston 5, intermeshing outside friction disc 16 and inner attrition piece 15, and the internal tooth of inner attrition piece 15 is meshed with driving gear 6 first line of a couplet all-in-one-piece clutch base; Piston 5 and return spring 17 are close together simultaneously on power shaft 1; One end of described Pulley shaft 23 is connected with an oil pump 20, and described oil pump 20 to be connected with clutch application valve 7 by oil circuit and when operation of oil pump, hydraulic oil to be sent into clutch application valve 7; The other end of Pulley shaft 23 is equipped with belt pulley, and is exported by belt.
When control valve handle rotates, the working oil of control valve is made to enter working piston through working oil path.Piston moves at the forced under pressure piston of working oil, outside friction disc in compressing, makes to be packed in clutch outer member on power shaft by outside friction disc, inner attrition piece, clutch base on driving gear drives driving gear to rotate, and makes driven gear and output shaft rotate together simultaneously.Power is exported by output shaft.
Because being fixed with driving bevel gear on power shaft simultaneously, when power shaft rotates, driving bevel gear drives the driven bevel pinion be packed on belt shaft to rotate together.Belt shaft is equipped with belt pulley, belt pulley by belt power stage.
Embodiment: as shown in Figure 1, 2, power shaft 1 is bearing on casing 10 by bearing 2 and bearing 8.Power shaft 1 is fixed with clutch outer member 4.Clutch outer member 4, built with piston 5, is equipped with the outside friction disc 16 be meshed simultaneously in clutch outer member 4, and inner attrition piece 15, and the internal tooth of inner attrition piece 15 is meshed with the clutch base on driving gear 6.Piston 5 is close together with return spring 17 simultaneously on power shaft 1.Driving gear 6 is arranged on and in relative rotation on power shaft 1, and can be meshed with the driven gear 13 on output shaft 12.Output shaft 12 is fixed with driven gear 13, output shaft 12 has bearing 14 and bearing 11 to be bearing on casing 10.
Power shaft 1 is fixed with driving bevel gear 9, and engages with the driven bevel pinion 22 that Pulley shaft 23 is fixedly mounted with, Pulley shaft 23 is bearing on casing 10 by bearing 21 and bearing 24.
When power shaft 1 rotates, the drive bevel gear 9 be packed on power shaft 1 drives the driven wheel of differential 22 that Pulley shaft 23 is fixedly mounted with to rotate, and belt shaft 23 is rotated, and power spreads out of from belt shaft 23.The other end of Pulley shaft 23 is connected with oil pump 20, and oil pump 20 makes operation of oil pump after rotating, and hydraulic oil enters in control valve 7.
When the handle on control valve 7 forwards binding site to, the working oil in control valve 7 enters in the working chamber of clutch outer member 4 by working oil path 18, promotes piston 5 and moves, outside friction disc in compressing.Diesel engine power passes through clutch outer member 4, outside friction disc 16, inner attrition piece 15, the clutch base on driving gear 6 from power shaft 1, and by driving gear 6, driven gear 13, output shaft 12 is by power stage.
When the control crank on control valve 7 forwards disengaged position to, working oil returns back out from working oil path 18, and piston is returned to original position by piston 5 under the effect of return spring 17.
The utility model achieves an input, exports using function by two of different requirement.
