Description
Technical field
The utility model relates to a kind of supporting used for diesel engine both-end power output structure on agricultural combine, and specifically the direct-connected power output structure of a kind of reinforced motor both-end belongs to the mechanical structure technical field.
Background technique
When corn harvester is or approaching maturation ripe at corn, according to agriculture requirement, be used for finishing the mechanical work agricultural machinery and implement to corn straw harvesting, be for new exploitation of energy resources and alleviate friend's peasant labor intensity and a kind of novel agricultural machinery researched and developed, be a kind of cheap, be fit to the farm machinery that the little four-wheel in supporting rural area comes the harvesting corn stalk.Corn harvester can shorten friend's peasant the work cycle, allows people free from heavy manual labor.And along with the preferential policy of country to farm machinery, some areas have reached 30% ~ 40% especially to the subsidy of corn harvester, the consumptive power that this has further stimulated market, and making in recent years, the corn harvester market anomalies prevails.But when national reaper market is very good, some technical problems have appearred also.
The most original corn harvester diesel engine is reequiped by engine for automobile on the Domestic market now, it adopts the kind of drive of traditional bent axle-flywheel-clutch-transmission shaft-universal joint-gearbox, its power output structure is clutch power output structure shown in Figure 1, among Fig. 1, the 1st, gear, the 2nd, flywheel, the 3rd, main axle bush, the 4th, thrust plate, the 5th, oil sealing base, the 6th, oil sealing, the 7th, bent axle, the 8th, bearing, the 9th, bolt of flywheel, the 10th, cover ﹠ plate assy., the 11st, clutch driven disc assembly, the 12nd, spline shaft, the 13rd, the declutch shaft bearing, the 14th, release bearing, the 15th, oil nozzle, the 16th, circlip, the 17th, back-up ring, the 18th, bearing, the 19th, clutch housing, the 20th, the spherical pillar of withdrawal fork, the 21st, disengaging yoke, the 22nd, the wheel cylinder support, the 23rd, the clutch slave cylinder support.The advantage of this clutch power output structure is that load carrying capacity is strong, the transfer of torque free of losses.But its shortcoming is obvious too, be specially: (1) is in use mainly born by clutch friction plate owing to the motor operation produces load, so the clutch friction plate spoilage is high, the clutch friction plate that motor just need more renew in average three to five days of operating at full capacity under the state, and owing to car load layout reason, the clutch dismounting is also extremely difficult, can't operate without special apparatus; (2) its supporting supporting facility is more, needs wheel cylinder, wheel cylinder support, disengaging yoke etc. are installed, and user cost is higher.(3) use is loaded down with trivial details, and oil nozzle 15 places need the frequent lubricant oil that adds.
On the basis of above-mentioned clutch power output structure, developed again a kind of monolateral belt pulley power output structure on the market, it is the most widely used a kind of power transmission structure on the present corn harvester market.This power output structure as shown in Figure 2, among Fig. 2, the 1st, gear, the 2nd, flywheel, the 3rd, main axle bush, the 4th, thrust plate, the 5th, oil sealing base, the 6th, oil sealing, the 7th, bent axle, the 8th, bearing, the 9th, bolt of flywheel, the 24th, belt pulley.In this power output structure, by belt transport power, belt pulley is directly installed on the flywheel reaper by belt pulley, and flywheel is connected with bent axle, and bent axle is supported by main axle bush.That the advantage of this power output structure is is simple in structure, cost is low, the new product development advanced development does not need producer to make the casting and molding mould, only need the car load manufacturer production that belt pulley is installed, just can make sample in several days joins for experiment or examination, manufacturing speed is fast, can simultaneous adaptation multi-varieties and small-batch and single variety production in enormous quantities.But its shortcoming is obvious too, be specially: (1) motor in the rear end by the v belt outputting power, the lateral force of belt is excessive when work like this, make that gap between bent axle and the main axle bush is too small can't to be formed oil film and cause main axle bush uneven wear, crankshaft wear, Rear oil seal wearing and tearing leakage of oil, even cause crankshaft breakdown.If belt tension is reduced, then belt slippage, be short of power; (2) because what damage all is engine interior spare, the general user is without maintainability, and send return-to-factory consuming time too much, and greatly affect user's utilization efficiency often only one month reaping corn season in the corn place of production.
For solving the shortcoming of above-mentioned belt pulley power output structure, producer has researched and developed again a kind of reinforced power output structure on this basis now, specifically as shown in Figure 3, among Fig. 3, the 1st, gear, the 2nd, flywheel, the 3rd, main axle bush, the 4th, thrust plate, the 5th, oil sealing base, the 6th, oil sealing, the 7th, bent axle, the 8th, bearing, the 9th, bolt of flywheel, the 24th, belt pulley, the 25th, lining, the 26th, soft key, the 27th, transmission shaft, the 28th, clutch housing, the 29th, bearing.Be flexible coupling by elastic key between transmission shaft in this reinforced power output structure and the flywheel, a leeway of buffering is arranged when making flywheel bear radial load, and transmission shaft is fixed by two bearings, further with radial load transfer to clutch housing, effectively avoided the faults such as power output structure causes before and after the conventional belt wheel bearing shell uneven wear, crankshaft wear, Rear oil seal wearing and tearing leakage of oil.But the shortcoming of this structure is obvious equally, is specially: (1) product uses part many, and cost of goods manufactured is large; (2) exist trial-production to revise the risk that size causes frock and mould retirement or scraps; (3) factory need have the casting ability just can manufacture production (or external coordination casting), but manufacturer's scope is little; (4) join the different dimensional structure of different main engine factory's different automobile types needs, need to make various moulding mould, so be not suitable for many variety production, especially be not suitable for less volume and more variety production.(5) structure is compact not, because country is now to all to some extent restrictions of reaping corn locomotive frame size, so cooperate this structure without enough spaces on most corn harvester.
