Abstract
A cam shaft for a diesel engine comprises a cam shaft body which comprises a first gas distribution cam, a second gas distribution cam, an oil pump cam and a cam shaft timing gear. The oil pump cam is located between the cam shaft timing gear and the second gas distribution cam. The second gas distribution cam is located between the oil pump cam and the first gas distribution cam. Due to the fact that the oil pump cam is located between the cam shaft timing gear and the second gas distribution cam, the oil pump cam, the first gas distribution cam and the second gas distribution cam on the diesel engine are located on one side of the cam shaft timing gear, machining is convenient, the overall machining precision of the cam shaft is improved, weight of the cam shaft is reduced, machining difficulty of the cam shaft is reduced, the overall structure of the diesel engine is more compact, failure points of the diesel engine are reduced, and the cam shaft for the diesel engine has the advantages of being small in size, low in weight and cost, and higher in use efficiency.
Description
Technical field
The utility model relates to diesel technology, particularly a kind of use for diesel engine camshaft.
Background technique
On the camshaft of existing common single cylinder diesel, cam of injection pump is installed, cam of injection pump is arranged on Valve Gear of Diesel intake and exhaust cam neutral position.Camshaft timing gear and camshaft are generally split type, split type must connection by a flat key, need Heat artificially camshaft timing gear to strike dress camshaft when installation again.This makes use for diesel engine camshaft exist complex structure, and volume is large, and difficulty of processing is large, makes troubles also to assembling, adjustment, maintenance Injection Pump.
Summary of the invention
According to above-mentioned technical problem, the utility model provide a kind of simple in structure, volume is little, processing technology is simple, unfailing performance is better, precision is higher, is convenient to a kind of use for diesel engine camshaft of I& M.
The technical solution of the utility model is as follows:
A kind of use for diesel engine camshaft, comprise camshaft, the first valve cam, the second valve cam, cam of injection pump and camshaft timing gear are installed on this camshaft, it is characterized in that: described cam of injection pump is between described camshaft timing gear and the second valve cam, and described the second valve cam is between described cam of injection pump and described the first valve cam.
Further feature, described the first valve cam, the second valve cam, cam of injection pump, camshaft timing gear and camshaft are one-body molded.
The beneficial effects of the utility model are:
Because cam of injection pump of the present utility model is between camshaft timing gear and the second valve cam, make cam of injection pump, the first valve cam and the second valve cam on diesel engine all be in camshaft timing gear one side, easy to process, and improve camshaft entirety machining accuracy, alleviate camshaft weight, reduced machining cam axle difficulty simultaneously, also make Diesel Engine Complete Machine structure compacter, reduce the fault point of diesel engine, reached the effect that volume is little, lightweight, cost is low, utilization efficiency is higher.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, a kind of use for diesel engine camshaft, comprise camshaft 5, the first valve cam 1, the second valve cam 2, cam of injection pump 3 and camshaft timing gear 4, the first valve cams 1, the second valve cam 2, cam of injection pump 3, camshaft timing gear 4 and camshaft 5 five are installed one-body molded on this camshaft 5.Wherein cam of injection pump 3 is between camshaft timing gear 4 and the second valve cam 2, and the second valve cam 2 is between cam of injection pump 3 and the first valve cam 1.
Because the cam of injection pump of use for diesel engine camshaft is between camshaft timing gear and the second valve cam, make cam of injection pump, the first valve cam and the second valve cam on diesel engine all be in camshaft timing gear one side, easy to process, reduce the complexity of machining cam axle technique, improve camshaft entirety machining accuracy, alleviate camshaft weight, reduced machining cam axle difficulty simultaneously, also make Diesel Engine Complete Machine structure compacter, reduce the fault point of diesel engine, reached the effect that volume is little, lightweight, cost is low, utilization efficiency is higher.
Above-described embodiment of the present utility model is to be only explanation the utility model example, and is not the restriction to mode of execution of the present utility model.For those of ordinary skill in the field, can also make on the basis of the above description other multi-form variation and variations.Here cannot give exhaustive to all mode of executions.Everyly belong to apparent variation or the still row in protection domain of the present utility model of variation that the technical solution of the utility model amplifies out.
