Abstract
A kind of engine nylon cylinder head cover, disposable injection molding nylon cylinder head cover (6), mounting hole (1) is set in the center of nylon cylinder head cover, in the pre-buried steel screw bushing in nylon cylinder head cover (6) side (2) in injection moulding process, another sidewall arranges reduction valve (3), another sidewall arranges positioning pin hole (4), many stiffening ribs (5) are set in nylon cylinder head cover (6), form engine nylon cylinder head cover overall structure.The utility model overcomes defects such as getting rusty, burn into is overweight, the life-span is short.The phenomenons such as the cylinder head cover that strenuous vibration causes ruptures, snaps, damage are produced when avoiding engine running.Reduce fabricating cost.Alleviate unit weight.The noise that when overcoming engine operation, air inlet and exhaust valve produce directly outwards is transmitted by cylinder head cover, continually sends ultrasound, the environmental pollution caused.
Description
Technical field
A kind of engine nylon cylinder head cover, relates to B portion---operation; Engine fittings nylon cylinder head cover technical field in transport class.
Background technique
Over a hundred or so year, traditional cylinder cover of engine major part adopts the casting such as cast iron, cast aluminium.This technology or material is apparent there is defects such as getting rusty, burn into is overweight, the life-span is short.Particularly produce violent vibrations during engine running, cause cylinder head cover to rupture, snap, the phenomenon such as damage happens occasionally.The noise that during engine operation, air inlet and exhaust valve produce directly outwards is transmitted by cylinder head cover, continually sends ultrasound, causes environmental pollution.And, process time-consuming traditionally, increase fabricating cost.Increase unit weight, this is the problem that many factories are difficult to overcome.
Summary of the invention
The object of the present invention is to provide a kind of to have the nylon composite materials absorbing and block noise function, the corrosion protection that alternative metals material makes, crack resistence, reduces costs, and alleviates unit weight, the engine nylon cylinder head cover of energy-conserving and environment-protective.
Main technical schemes:
Disposable injection molding nylon cylinder head cover (6), mounting hole (1) is set in the center of nylon cylinder head cover, in the pre-buried steel screw bushing in nylon cylinder head cover (6) side (2) in injection moulding process, another sidewall arranges reduction valve (3), another sidewall arranges positioning pin hole (4), many stiffening ribs (5) are set in nylon cylinder head cover (6), form engine nylon cylinder head cover overall structure.
Due to above technological scheme, the utility model overcomes defects such as getting rusty, burn into is overweight, the life-span is short.The phenomenons such as the cylinder head cover that strenuous vibration causes ruptures, snaps, damage are produced when avoiding engine running.Reduce fabricating cost.Alleviate unit weight.The noise that when overcoming engine operation, air inlet and exhaust valve produce directly outwards is transmitted by cylinder head cover, continually sends ultrasound, the environmental pollution caused.

Fig. 2 is the side view cutaway drawing of engine nylon cylinder head cover
1 mounting hole, 2 steel bushings, 3 reduction valve, 4 positioning pin holes, 5 stiffening ribs, 6 nylon cylinder head covers.
Embodiment
Select the rigidity nylon material of excellent performance, utilize Shooting Technique, disposable injection molding nylon cylinder head cover 6, arranges mounting hole 1 in the central position of nylon cylinder head cover, is convenient to be connected with motor.In the ganoid steel screw bushing 2 that the pre-buried process in nylon cylinder head cover 6 side grinds in injection moulding process, be convenient to the lubrication state checking motor in time.Another sidewall arranges reduction valve 3, the automatic pressure regulation when engine pressure increases.Another sidewall arranges positioning pin hole 4, accurately locates when being convenient to be connected with engine cylinder-body.Many stiffening ribs 5 are set in nylon cylinder head cover 6, to strengthen rigidity and the intensity of cylinder head cover entirety.Form engine nylon cylinder head cover overall structure thus.
Claims (1)
