Abstract
The utility model discloses an engine cam shaft, which comprises a shaft body, a gear, an air inlet cam and an air outlet cam, wherein the gear is arranged at one end of the shaft body, both the air inlet cam and the air outlet cam are sleeved on the shaft body, the air inlet cam is close to the gear, the shaft body is internally provided with a primary oil channel along the axial direction, a separator is arranged at one end in the primary oil channel and close to the gear and an oil plug is arranged at the other end of the primary oil channel. The shaft neck of the shaft body is provided with a secondary oil channel communicated with the primary oil channel. The cam shaft is provided with a lubricating oil channel, thus the number of the oil channels on a cylinder cover is reduced, the difficulty of machining is reduced, the cost is saved and the working efficiency is increased.
Description
Technical field
The utility model relates to a kind of motor, particularly a kind of engine cam.
Background technique
Camshaft is as internal combustion engine critical components such as gasoline, diesel oil; All adopt metal casting for a long time; The mode of machining is made, because complex process, manufacture cost height and manufacturing efficiency are lower; Along with the application popularization of float amount internal combustion engine, reduce the research topic that the camshaft parts cost becomes numerous project planners.Existing motor need be provided with a large amount of oil ducts on cylinder cap, and on cylinder cap, arranges with the processing and lubrication oil duct quite difficultly, and the machining difficulty is big, and cost is higher.
Summary of the invention
The purpose of the utility model just is to provide a kind of engine cam easy to process, lower-cost, can effectively address the above problem.
To achieve these goals; The technological scheme that the utility model adopts is such: the engine cam of the utility model, comprise axis body, gear, intake cam and exhaust cam, and gear is arranged on an end of axis body; Intake cam and exhaust cam all are socketed on the axis body; Intake cam is provided with main oil gallery vertically near gear in the said axis body, the end near gear in the main oil gallery is provided with divider; The other end end is provided with stifled oily part, and the axle journal place of axis body is provided with the secondary oil duct that communicates with main oil gallery.
Further, said intake cam and exhaust cam constitute by pre-shaping layer and the final shaping unit layer that is coated on this pre-shaping layer.
Further again, said divider is steel ball with stifled oily part, and steel ball and main oil gallery adopt interference to be sealed and matched.
Further, said gear is made up of metal panel beating embedded part and engineering plastics coating, and coating covers the surface of embedded part, and embedded part is fixed on the axis body.
Compared with prior art, the advantage of the utility model is: camshaft self be provided with oil leab, reduced the quantity that oil duct is set on cylinder cap, reduced mach difficulty, practice thrift cost, improved working efficiency; Intake cam and exhaust cam constitute by pre-shaping layer and the final shaping unit layer that is coated on this pre-shaping layer; Gear is made up of metal panel beating embedded part and engineering plastics coating; After intake cam and exhaust cam and gear forming are decomposed; Can use different engineering plastics, the working life of having improved camshaft according to cam and the different effect of gear.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
To combine accompanying drawing that the utility model is described further below.
Referring to Fig. 1, the engine cam of the utility model comprises axis body 1, gear 9, intake cam 2 and exhaust cam 3; Gear 9 is arranged on an end of axis body 1, and intake cam 2 all is socketed on the axis body 1 with exhaust cam 3, and intake cam 2 is near gear 9; Be provided with main oil gallery 4 vertically in the said axis body 1, the end near gear 9 in the main oil gallery 4 is provided with divider 6, and the other end end is provided with stifled oily part 7; The axle journal place of axis body 1 is provided with the secondary oil duct 8 that communicates with main oil gallery 4, and said intake cam 2 constitutes by pre-shaping layer and the final shaping unit layer that is coated on this pre-shaping layer with exhaust cam 3, and said divider 6 is steel ball with stifled oily part 7; Steel ball and main oil gallery 4 adopt interference to be sealed and matched; Said gear 9 is made up of metal panel beating embedded part and engineering plastics coating, and coating covers the surface of embedded part, and embedded part is fixed on the axis body 1.
Lubricant oil enters in the main oil gallery 4 from oil inlet hole 5, and lubricant oil flows on the corresponding axle journal through each secondary oil duct 8, and unnecessary lubricant oil flows back in the cylinder cap behind the camshaft lubrication; Camshaft self be provided with oil leab, reduced the quantity that oil duct is set on cylinder cap, reduced mach difficulty, practice thrift cost, improved working efficiency; Intake cam 2 constitutes by pre-shaping layer and the final shaping unit layer that is coated on this pre-shaping layer with exhaust cam 3; Gear 9 is made up of metal panel beating embedded part and engineering plastics coating; After intake cam 2 and exhaust cam 3 and gear 9 moulding are decomposed; Can use different engineering plastics, the working life of having improved camshaft according to cam and gear 9 different effects.
Claims (4)
1. an engine cam comprises axis body, gear, intake cam and exhaust cam, and gear is arranged on an end of axis body; Intake cam and exhaust cam all are socketed on the axis body; Intake cam is characterized in that near gear: be provided with main oil gallery in the said axis body vertically, the end near gear in the main oil gallery is provided with divider; The other end end is provided with stifled oily part, and the axle journal place of axis body is provided with the secondary oil duct that communicates with main oil gallery.
