Abstract
The utility model relates to a crankcase device for a single-cylinder diesel engine. The traditional crankcase of a general single-cylinder diesel engine is integrated with a gear chamber, a baffle between the crankcases and the gear chamber can be canceled, and the crankcase device comprises a crankcase body and a crankcase cover. A crank shaft and a cam shaft are supprorted respectively on the crankcase body and the crankcase cover, and both ends of the crank shaft can extend and can output respectively the power. A rabbet is arranged on the crankcase cover, and the high-degree direct connection of the crankcase cover and a matched implement can be convenient and the starting method can be the rope pulling or electric starting. The casting and the assembly technique of the whole case body device can be improved greatly, the utility model has the advantages of simple structure, compact structure and convenient repair and use, and is a practical crankcase device for the general single-cylinder diesel engine.
Description
The utility model relates to a kind of crankcase device of single cylinder diesel, there is a dividing plate that they are separated between crankcase in the domestic general single cylinder diesel body and the gear chamber, one end bearing of bent axle, camshaft is in the outside of body, the other end is bearing on the dividing plate, power output is at the crankshaft-flywheel end, by belt pulley or coupling output power; Cam of injection pump is located at the cantilever end outside camshaft two supporting points; The speed regulator element is contained on the bent axle; Start mode is hand speedup starting.The major advantage of this structure is the body good rigidly; The machine coordination that is suitable for various rotating speeds.Deficiency is that body volume is big, in order to assemble, needs to open side window on body, and casting manufacturability is poor, and assembling is inconvenient; Can not realize the height direct connection, Belt Transmission Efficiency is lower, and the coupling transmission requires high to power and facility coaxality; The camshaft cantilever end is long, poor rigidity; The speed regulator element is responsive to the reaction of bent axle axial float, and is unfavorable for the crankshaft two end output power; Hand starting has increased a pair of driving gear, and the cost height also is unfavorable for the crankshaft two end output power.
The purpose of this utility model be provide at the deficiency of above-mentioned technology a kind of simple in structure, compact, easy to use, assembly process process is good, crankshaft two end is the single cylinder diesel crankcase device of exportable power all.
The utility model is achieved in that it has a crankcase body that traditional crankcase and gear chamber are combined together, has crankcase cover on the crankcase body.Bent axle, camshaft, trunnion shaft are bearing in respectively on crankcase body and the crankcase cover.
For the ease of with outfitting tool height direct connection, seam is arranged on the crankcase cover.
Crankshaft two end stretches out crankcase body and crankcase cover respectively, has rope pull-up Moving plate or electric starting device both can save a pair of gear at the end that flywheel is housed, and starts more convenient.
Cam of injection pump between the inlet and outlet cam, good rigidly.
Description of drawings:
Fig. 1 is the crankcase of general single cylinder diesel and the structure diagram of gear chamber.
Fig. 2 is the utility model housing structure sketch.
Now illustrate in detail with regard to structure of the present utility model and working principle in conjunction with the accompanying drawings:
Crankcase 12 in Fig. 1 body is what to be separated with gear chamber 13, has between them every pulling 14, and bent axle, camshaft supporting are on body and dividing plate.The crankshaft-flywheel end is by belt pulley or coupling output power; Cam of injection pump is located at the cantilever end outside camshaft two supporting points; Start mode is that hand speedup starting has increased a pair of overdrive gear, the cost height, and because the restriction of structure is unfavorable for the crankshaft two end output power; For the ease of assembling, must open side window on the body, the body casting technique is comparatively complicated.Fig. 2 is the utility model housing structure sketch: the dividing plate 14 in the body is cancelled, and crankcase body 4 adds crankcase cover 5 and constitutes a complete crankcase, and cabinets cavity is the bathtub construction of open type, is suitable for high pressure die casting.Bent axle 1 camshaft 2, trunnion shaft 3 two ends are bearing in respectively on crankcase body 4 and the crankcase cover 5.During assembling, earlier parts in addition all in the case is loaded onto one by one, and then loaded onto crankcase cover 5, very convenient.Crankcase body 4 and case lid 5 are all stretched out in the two ends of bent axle 1.On one end of bent axle flywheel 11 is arranged, the flywheel end is equipped with rope pull-up Moving plate 7, or electric starting device and can thong dish or coupling output power.The other end of bent axle 1 is a power master output terminal, and crankcase cover 5 is provided with the seam 6(SAE standard of being convenient to outfitting tool height direct connections such as pump class, generators).Cam of injection pump 8 is located in the middle of the intake and exhaust cam 9,10, has saved the cantilever end of camshaft, and rigidity is greatly improved.
Because the utility model improves body structure, not only the casting manufacturability of casing is improved, and other assembly process process of parts also is improved in the case. Particularly crankshaft two end all stretches out outside the body, and two ends can power output, and matching performance greatly improves. It is that the rope starter disc type is easy to use that start mode changes hand speed-increasing type, and cost is low. Package unit is simple in structure, compact. It will be widely used in using on the single cylinder diesel.
