Description
Technical field
The utility model relates to a kind of transmission device, especially is contained in the built-in speed changer of the final output speed of change diesel engine on the diesel engine power output terminal.
Background technique
Along with the sustainable development of national economy high speed, some areas power supply remains in certain gap, quite a few enterprise, and especially private small enterprise is owing to the not enough production and operation of power supply are under some influence.The small diesel engine generator set is inexpensive, light and handy with it, the characteristics of conveniently moving, can replenish a part of electric power and is subjected to user favor, and certain market demand is arranged.
China's grid power frequency is 50 hertz, so generator speed is generally 1500 rev/mins, and the diesel engine development that drives generator generally all is speed up so far, and its output speed all is higher than 1500 rev/mins.The miniature diesel generator set of Domestic market supply at present, diesel engine is connected with the elasticity union joint with generator, directly drives generator work by diesel engine.Diesel engine makes the diesel engine output speed reduce to 1500 rev/mins by the change of speed regulator own.The deficiency diesel engine output speed of this technology reduces output power and also reduces thereupon.The B490 diesel engine output speed of producing as Xinjiang Internal-Combustion Engine Factory, Shanghai is 2700 rev/mins, and its output power is 36 kilowatts, and its output power only is 22 kilowatts when being 1500 rev/mins as change speed regulator diesel engine output speed; The diesel engine fuel consumption rate in the time of 2700 rev/mins be 240 the gram/kilowatt-hour, in the time of 1500 rev/mins fuel consumption rate be 260 the gram/kilowatt-hour.This shows that diesel engine passes through the change of self speed regulator, drive generator for electricity generation by the output speed of reducing to 1500 rev/mins at a high speed, this technology is to descending the diesel engine output power, and fuel consumption rate increases,. the diesel engine output power is not fully exerted, and diesel engine work is uneconomical.
Summary of the invention
In order to solve above-mentioned deficiency of the prior art, the utility model provides a kind of diesel engine built-in speed changer, become 1500 rev/mins with the high output speed that solves diesel engine in the diesel power generation unit by this device output speed that diesel engine is final under the prerequisite that keeps this diesel engine output power not descend, to guarantee that diesel generating set sends power frequency is 50 hertz, diesel engine is given full play to output power, and works in the economic zone.The technical solution of the utility model is that the built-in speed changer of a kind of diesel engine comprises gear box casing, the gearbox fishplate bar, driving gear, internal gear, main shaft, left side shaft-cup and right shaft-cup, it is characterized in that this built-in speed changer is contained on the flywheel casing of diesel engine power output terminal forms an integral body with diesel engine, on the flywheel of diesel engine, load onto a power output shaft, power output shaft passes the gearbox fishplate bar and puts in the cavity of gear box casing, driving gear is housed on the power output shaft, be fixed on internal gear and its engagement on the main shaft, gear box casing and gearbox fishplate bar form a sealed cavity and are fixed on the flywheel casing of diesel engine power output terminal, main shaft is fixed on the gear box casing by two roller bearings and by left shaft-cup and right shaft-cup, and main shaft is loaded onto union joint at the external end of transmission housing and is connected with generator.When diesel engine is worked, export by the diesel engine flywheel rate of doing work, the flywheel running drives the driving gear running on the power output shaft, driving gear drives passive internal gear running, because passive internal gear is fixed on the transmission main shaft, drive generator for electricity generation by transmission main shaft through union joint, whole diesel generating set working speed is 1500 rev/mins, and the generating frequency is 50 hertz.

Embodiment
As shown in Figure 1, a power output shaft is fixed on the diesel engine flywheel 24, and power output shaft passes gearbox fishplate bar 4 and puts in the cavity of gear box casing 5, seals with outside framework oil seal 3 between power output shaft and the gearbox fishplate bar 4; Driving gear 6 is housed on the power output shaft, and driving gear 6 is fixed on the power output shaft by flat key 1, driving gear pressing plate 2, bolt 8, and meshes with the internal gear 7 that is fixed on by bolt 9 on the main shaft 16; Main shaft 16 is supported by two rolling bearings 12 and 20 respectively, between the rolling bearing 12 and 20. be mounted with back-up ring 13, and be fixed on the gear box casing 5 by left shaft-cup 11 and right shaft-cup 18 usefulness bolts 10, packing ring 21 respectively, be mounted with round nut 14 and round nut thrust washer 19 and outside framework oil seal 17 between rolling bearing 20 and the right shaft-cup 18; Gear box casing 5 and gearbox fishplate bar 4 form a sealed cavity and are fixed on the flywheel casing 25 of diesel engine power output terminal, cover plate 22 and resuscitation apparatus 23 are housed in the upper end of gear box casing 5, a certain amount of lubricant oil of storage keeps certain lubricant oil liquid level in this cavity; The end use key 15 of main shaft 16 outside gear box casing 5 loaded onto union joint 28 and is connected with generator 29.
As shown in Figure 2, when diesel engine 26 work, being contained on the flywheel casing of diesel engine power output terminal the built-in speed changer 27 of diesel engine of forming an integral body with diesel engine also starts working, export by the diesel engine flywheel rate of doing work, the flywheel running drives the driving gear running on the power output shaft, driving gear drives passive internal gear running, a pair of gear turns round in the lubricant oil high speed, by splashing of lubricant oil gear and rolling bearing are lubricated, on the right shaft-cup of main shaft with the gearbox fishplate bar on the outside framework oil seal settled prevented the seepage of lubricant oil, the resuscitation apparatus in the gear box casing upper end can go out by Vent when making the gear box casing inner air pressure be higher than atmospheric pressure.Because passive internal gear is fixed on the transmission main shaft, drive generator for electricity generation by transmission main shaft through union joint, whole diesel generating set working speed is 1500 rev/mins, the generating frequency is 50 hertz.
On the B490 diesel engine, be applied as the effect that routine fork-like farm tool used in ancient China illustrates the built-in speed changer of this diesel engine with the utility model below.The B490 diesel engine directly is connected with generator by union joint, the speed regulator of change diesel engine self makes the diesel engine output speed drop to 1500 rev/mins by intrinsic 2700 rev/mins, this moment whole diesel generating set output power only be 20 kilowatts, fuel consumption rate be 260 the gram/kilowatt-hour; After the B490 diesel engine is loaded onto the speed changer of the inside and outside gear engagement of 5 moduluses, 2700 rev/mins of the output speeds of diesel engine, 36 kilowatts of output powers, through the built-in speed changer of the utility model diesel engine, making the final output speed of diesel engine is 1500 rev/mins (output power still is 36 kilowatts), this moment whole diesel generating set be 30 kilowatts, the diesel engine fuel consumption rate be 240 the gram/kilowatt-hour.Effect is significant, has solved the deficiencies in the prior art, has satisfied social demand.
