Description
Technical field
The utility model relates to a kind of starting arrangement of diesel engine, is particularly suitable for the diesel engine starting below 25 horsepowers.
Technical background
At present, being used for the diesel engine on various tractor with small four wheels, hand tractor, agricultural vehicle and the equipment of small motor ship, is that armrest shakes starting all, operation inconvenience, and winter, starting was more difficult, but also the incident of hurting sb.'s feelings easily.For solving the starting problem of diesel engine, many people did the research of diesel engine starting device, and also had Evaluation product to occur, but they all exist a fatal defective, are exactly complex structure, and heaviness is installed and used inconvenience, and the life-span is low, poor reliability.My another patent " a kind of hydraulic-pressure type diesel engine starter motor " adopts the principle of hydraulic accumulation energy, the energy that produces when diesel engine is worked is by the rotation of hydraulic pump drive gear, store the energy in the spring, can the energy in the spring be discharged control mechanism as long as operation is released when starting machine once more.Simple in structure, esy to use, safe and reliable.But find in production practices: this hydraulic-pressure type diesel engine starter motor is to utilize oil hydraulic pump to promote push rod to roll spring, relies on the rotation of cam that push rod is resetted again; When spring is rolled onto last the time, need oil hydraulic pump to produce very large thrust and just may promote push rod, like this to the requirement of oil hydraulic pump just than higher, be cost to raise the cost and to reduce reliability.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, the hydraulic efficient starter of diesel engine that cost of production is low, reliability is high.
The technical solution of the utility model is: a kind of hydraulic efficient starter of diesel engine, comprise housing, and main shaft and hollow shaft are installed on the housing, main free wheel device is installed on the main shaft, gearwheel and accumulator are installed on main free wheel device; Main free wheel device comprises the clutch cover that is installed on the main shaft, is connected with needle roller between clutch cover and the main shaft; One end of main shaft is connected with diesel engine by coupling; On main shaft, be connected with the energy storage control mechanism that can make the accumulator stored energy; Releasing of can making that accumulator releases energy is installed on hollow shaft can control mechanism; Said energy storage control mechanism comprises the eccentric cam that is installed on the main shaft, be installed in hydraulic cylinder piston group on the housing, an end is pressed in driving lever on the cam by the hydraulic piston group, and the other end of this driving lever and hollow shaft and the needle roller between the two constitute secondary free wheel device; Small gear is installed on the hollow shaft and with gearwheel and meshes; The oil pump and the limiting valve of control oil pressure are installed on housing; Said releasing can comprise the switch starter that is installed in hollow shaft inner chamber one end by control mechanism; Be installed in the clutch positioning ball that is used for controlling pinion rotation on the hollow shaft; Be connected with Returnning spring between the other end of the inner of switch starter and hollow shaft inner chamber; On housing, be equipped with and the corresponding operating crank of switch starter; Be connected with one-way element between hollow shaft the inner and the housing; Be connected with return spring between the housing of driving lever and hydraulic cylinder piston group one side, the one-way element that is connected between hollow shaft the inner and the housing and the direction of the secondary free wheel device between driving lever and the hollow shaft are to promote the small gear rotation when making eccentric cam jack-up driving lever.
For the diameter that reduces clutch cover and improve frictional force, the band of position of the corresponding needle roller of the inwall of above-mentioned clutch cover is fluted.
For convenience at the time standby crank rotating spindle of maintenance diesel engine, an end of main shaft is connected with diesel engine by coupling, and the other end stretches out outside the housing, and has the connection set that can connect crank.
After adopting technique scheme, thereby promote the small gear rotation in the time of eccentric cam jack-up driving lever and drive the gearwheel stored energy, what the driving lever return relied on is the pulling force of return spring, the effect of hydraulic cylinder piston group only is to overcome the pulling force of return spring driving lever is pressed on the eccentric cam, active force is little, to oil hydraulic pump require lowly, can reduce production costs significantly and improve reliability of products.The groove of the inwall of clutch cover can increase frictional force, dwindles the diameter of free wheel device.
