Abstract
The present invention relates to a special-purpose cranking bar for starting diesel engine. It is characterized by that its front neck end is equipped with an one-way roller-type clutch, it uses the action of said one-way clutch which can be seized up clockwise and not slipped to drive crankshaft to make synchronous rotation. When the rotating speed of the crankshaft exceeds the one-way clutch with inertia of flywheel, the on-way clutch can produce "slipping" action, so that it can prevent the cranking bar from slipping or declutching to injure human. When cranking by hand, it can save labour, and can shorten continuous compression time of air heated in cylinder of diesel engine so as to easily ignite diesel oil.
Description
The present invention relates to diesel engine and with the diesel engine be power as middle-size and small-size means of transportation such as car, ships, especially for the handle device of diesel engine starting.
More present medium and small-scale diesel engines are used for hand driving crank mostly makes the diesel engine compression ignition.Because the air that compression stroke ends is to depend on that ambient temperature, gas lack the temperature of wall and the length of compression time mostly, so also relevant with speed of crankshaft.If rotating speed is low, will increase because of compression time length, heat radiation, gas leakage, the air temperature of compression end of a period is reduced, and fuel is difficult for catching fire.Owing to be approximate helical teeth structure engages between crank and the bent axle, when so speed of crankshaft surpasses crank, crank is from initiatively becoming passive, be forced to outwards move along the helical teeth screw thread, if this moment the crank rotating speed with bent axle equidirectional the same or near the time, then be to be forced to along with bent axle idle running is shaken, the muscle power that consumes the people is slowed down hand speed, yet this moment is in order to make compression time short, have only and firmly quicken hand speed, as long slightly with the bent axle idle running or the time of skidding, it is excessive that people's muscle power is consumed, so hand speed does not catch up with the speed of bent axle, the equidirectional speed distance of crank and bent axle zooms out, be forced to and bent axle is thrown off, or the people that under the rotatory inertia effect, injures when throwing off: or the people causes the accident along with crank inertia dumps forward, and these accident phenomenons are very widely.
The objective of the invention is to provide a kind of improved handle, it can prevent from long slightly the people to be short of physical strength because of hand starting causes hand speed along with the equidirectional sky of bent axle shakes the time effectively, can not quicken hand continuously and along with injure people and dumping forward of the crank rotatory inertia of throwing off causes the accident; Simultaneously laborsavingly can accelerate hand speed again and be more than bent axle the short diesel engine of compression time is easily caught fire.
The object of the present invention is achieved like this: increase between crank and bent axle engagement and adorn a main body overrunning clutch, it is to be connected with crankshaft end with bent axle helical teeth structure engages or body front end that body front end connects the helical teeth structure, body rear helical teeth structure and rocking handle front neck end helical teeth structure engages.The effect driving crank that utilizes the overrunning clutch clockwise direction to be stuck non-slip together rotates, when speed of crankshaft along with the inertia of flywheel and when surpassing overrunning clutch, overrunning clutch plays " skidding " effect.
The present invention adorns an overrunning clutch because of only increasing between crank and bent axle engagement, so structure is simple and easy to realize especially; Because it is long slightly and throw off that the starting point is to have prevented that hand speed from shaking the time with the bent axle sky, the short diesel engine of compression time is easily caught fire and but also fool proof so make the people labour-saving can accelerate not only hand speed simultaneously especially.
Describe the device details and the working condition that propose according to the present invention and combine with crank with unidirectional roller clutch below in detail.
Overrunning clutch through the transformation of the way make the cross piece in former shell sense of rotation with original opposite, remove the overrunning clutch front end starting (driving) small gear need not, reconfiguration handle front neck end helical teeth structure on the original position that removes; Remove again the overrunning clutch rear end screw sheel need not, at the rocking handle that removes reconfiguration handle on the original position.Picking up special-purpose cranking bar during use makes front neck end helical teeth structure and thick bent axle helical teeth structure engages and firmly shakes diesel engine starting is caught fire.
Special-purpose cranking bar action principle: because of the shell and the gap between the cross piece of overrunning clutch is that width does not wait (being wedge slot), when special-purpose cranking bar and the equidirectional rotation of bent axle, pass to the cross piece by rocking handle, because the cross piece together rotates in company with rocking handle, then roller just rolls into narrow space and is stuck, so driving crank; When bent axle under the flywheel effect of inertia and the equidirectional rotation of cross piece, and speed is greater than the cross piece, so roller just rolls into wide space, since front neck end helical teeth structure still with bent axle helical teeth structure engages, make crankshaft torque can not pass to the rear end rocking handle so overrunning clutch " skids ", people muscle power is consumed or throw off and easily cause casualty accident so avoided shaking with the bent axle sky; The effect that utilizes overrunning clutch " to skid " is simultaneously grasped in the optimum position hand action arbitrarily, and the quick hand of exerting oneself again when bent axle just will be lower than hand rotating speed makes the air that temperature raises in the cylinder of diesel engine continue the shorter fuel fire that easily makes of compression time.
Also can connect a suitable length rocking bar in the overrunning clutch rear end, the rocking bar the other end is cubic build.The corresponding handle in front and back has Nei Yuan hole supporting frame, return spring, defining flange, there is Nei Yuan hole back support frame to be inserted on the rocking bar, the back and front supporting frame is fixed on the fore poppet and bumper of middle-size and small-size car, makes overrunning clutch front neck end helical teeth structure aligning crankshaft end helical teeth structure and leave throw-off distances.Adjust defining flange with holding tight rocking bar, return spring is slightly withstood on the front support stand, and flange is fixed on the rocking bar.During larry, the rocking handle that cubic hole is arranged is inserted in stretches out on the outer rocking bar tetragonal body of bumper, break forward into make whole device move axially with the bent axle engagement after firmly hand, diesel engine is caught fire.Take off rocking handle after diesel engine catches fire, under the effect of return spring, the whole device return that outwards rebounds is unlikely with crankshaft end and collides.
Another kind is: overrunning clutch front end and crankshaft end are with being threaded, and former crankshaft end helical teeth structure and former rocking handle front neck end helical teeth structure engages are made in the overrunning clutch rear end; Or be rocking handle four directions borehole jack one main rod end on the cubic build and can conveniently take off and put, the rear end helical teeth structure engages of the overrunning clutch the other end that the helical teeth structure of the rocking bar the other end is connected with crankshaft end, also use defining flange, spring can separate engagement as return and has front and back, Nei Yuan hole supporting frame to be fixed on the vehicle frame with two.
