Description
Technical field
The utility model is related to cylinder cover for diesel engine systems technology field, and in particular to a kind of Novel air cylinder housing lid handwheel
Device.
Background technology
Cylinder head assembly is diesel engine important component, top surface of cylinder cover equipped with valve assembly, rocker shaft bed, rocker arm shaft, shake
Arm, transverse arm spring and lateral arm guide pole etc..Valve mechanism cover lid is located at the top of cylinder head assembly, to the reliable of the part of valve actuating mechanism
Property, cleannes, security etc. have protective effect, to ensure the safety in diesel engine running.Due to the operation in diesel engine
During, it is necessary to repeatedly adjusted to valve clearance etc., so valve mechanism cover lid herein needs to carry out dismounting repeatedly,
Diesel engine was run after a period of time, and the phenomenon of oil leak is occurred in that at valve mechanism cover lid handwheel.
Therefore a kind of Novel air cylinder housing lid handwheel devices are provided, can be fully sealed with valve mechanism cover, and through being dismounted for multiple times
Sealing property does not also change, and becomes those skilled in the art's urgent problem to be solved.
Utility model content
The utility model provide a kind of Novel air cylinder housing lid handwheel devices, possess valve mechanism cover can be fully sealed and
The characteristics of not changed through being dismounted for multiple times sealing property.
The technical solution adopted in the utility model is as follows：
A kind of Novel air cylinder housing lid handwheel devices, including cover lid, studs, sealing gasket, packing ring and cover lid hand
Wheel, cover lid handwheel is provided with the internal thread matched with studs, and cover lid is arranged in cylinder head and passes through one end and cover lid hand
The studs of wheel threaded connection is detachably connected, and cover, which is covered, is provided with boss on the lateral surface at the position that is connected with cylinder head,
Be provided with the boss conical surface at the top of the endoporus of boss, packing ring be through at sealing gasket on studs and positioned at cover lid handwheel and boss it
Between, cover lid handwheel, packing ring, sealing gasket and boss are sequentially connected, and the side endoporus that packing ring is connected with sealing gasket is bored provided with packing ring
Face, sealing gasket both sides are respectively equipped with the sealing gasket being engaged with the packing ring conical surface and the boss conical surface conical surface under the conical surface and sealing gasket.
Further, the angle of the boss conical surface and vertical plane is 60 °.
Further, studs, sealing gasket, packing ring, cover lid handwheel and boss are two, and are covered in cover and be in
It is symmetrical.
Compared with prior art, the utility model has the advantages that：
The utility model is simple in construction, easy for installation, can reach the requirement that valve mechanism cover is fully sealed, and through being dismounted for multiple times
Sealing property does not change, and solves quality problems of the diesel engine cylinder head cover lid using easy oil leakage after a period of time.
Packing ring endoporus of the present utility model is set to the conical surface, the upper cone match with sealing gasket；The lower conical surface of sealing gasket with it is convex
The platform conical surface is engaged, it is ensured that oil leak situation is occurred without at axial gap.Valve mechanism cover lid inner bore chamfering is set to 60 °, preferably
With cone match under sealing gasket, sealing effectiveness is reached.
During valve mechanism cover lid arrangement, cover lid handwheel is pressed on packing ring, sealing gasket by studs by screw-down torque
On the boss of valve mechanism cover lid.Due to the packing ring with the conical surface, sealing ring, rational screwing force is added, by conical surface seal and end
The extruding in face produces dual-seal axially with end face, and drawing requirement is fully achieved in sealing property, and may insure for a long time
The interior replacing without part.
Using the utility model, processing charges can be saved, cost of labor is reduced.It is first/small with cost of labor B=80 per hour
When, processing cover lid handwheel saves time k=180S；M=2, handwheel is installed on 16V diesel engines on each case；Diesel engine：Cylinder
Number presses Ne=16, produces diesel engine quantity N=80 platform meters, the cost of labor saved for 1 year per year：B*Ne*N*k*m=80*16*80*
180*2/3600=1.024 ten thousand (member).
