Abstract
The utility model relates to a valve push rod assembly. A push rod tube is a hollow cylindrical tube; both ends of the push rod tube are respectively welded with a convex ball and a concave head; one end of the convex ball is an external spherical surface, and the other end of the convex ball is a cavity which has the same diameter with the inner cavity of the push rod tube; one end of the concave head is an internal spherical surface, and the other end of the concave head is a hollow cavity which has the same diameter with the inner cavity of the push rod tube. Proved by an assembly test, the structure of the valve push rod assembly is reasonable, and the comprehensive performance indexes meet the operation requirements.
Description
Technical field
The utility model relates to the valve actuating push rod assembly on the motor.
Background technique
The valve actuating push rod assembly belongs to an important assembly in the valve mechanism, and its performance directly influences the performance of whole distribution device, directly influences the quality of whole motor.Steyr Europe III engine valve push rod assembly, adopted external import in the past, but external import has a lot of inconvenience: the one, and the supply of material is inconvenient, the 2nd, the bad coordination of quality problems, the 3rd, cost an arm and a leg, unreasonable structure etc., for this reason we developed this valve actuating push rod assembly and improved before deficiency.
Summary of the invention
For avoiding above drawback, the utility model has improved the structure of valve actuating push rod assembly, is more suitable for using in motor.
The utility model is made up of protruding ball, recessed head, pusher tube three parts, pusher tube is a columniform hollow tubular, be welded with protruding ball and recessed head at the two ends of pusher tube, one end of plush copper is an outer spherical surface, the other end is the cavity consistent with the pusher tube intracavity diameter, one end of recessed head is an inner ball surface, and the other end is the cavity consistent with the pusher tube intracavity diameter.
The characteristics of valve actuating push rod assembly:
1, each part material difference will be connected into integral body through Resistance Welding
2, special, each position tolerance strictness of surface configuration
3, core is organized strictly, and surface quality requires high, and inside and outside spherical surface all is in high-speed motion state, should guarantee that self is wear-resisting, guarantees again the component that match not to be caused wearing and tearing.
Each part of the utility model adopts different materials to make, its profile characteristics, the size at each position, geometrical shape and mechanical property, surface quality are all used with it and are adapted, each part of valve actuating push rod assembly adopts special processing technology moulding, improves tissue through Overheating Treatment then, high-accuracy machine tool mechanical processing, the centre is heat treatment repeatedly, according to using the branch position to carry out surface treatment, tolerance of size, surface quality are strict, and inside and outside spherical surface should wear-resisting flexible again.
Description of drawings
Now the utility model is described in further detail in conjunction with the accompanying drawings
Fig. 1 is the utility model overall structure schematic representation
Among the figure 1, recessed 2, weld seam 3, cavity 4, pusher tube 5, weld seam 6, protruding ball
Embodiment
As shown in Figure 1, the utility model is made up of protruding ball 6, recessed 1, pusher tube 4 three parts, pusher tube 4 is a columniform hollow tubular, the center of pusher tube 4 is a cavity 3, be welded with protruding ball 6 and recessed 1 at the two ends of pusher tube 4, an end of protruding ball 6 is an outer spherical surface, and the other end is and the consistent cavity of pusher tube 4 intracavity diameters, an end of recessed 1 is an inner ball surface, and the other end is the cavity consistent with the pusher tube intracavity diameter.
Steyr Europe III motor makes valve actuating push rod functional with the unique texture and the inherent technical order of valve actuating push rod assembly, makes whole distribution device energy good operation, can rotation when the special shape of internal and external spherical surfaces has guaranteed motion.The special technical requirement of internal and external spherical surfaces makes valve actuating push rod assembly self wear-resisting and grinding is even, tappet, adjustment screw are not caused wearing and tearing, the specific (special) requirements of profile makes it wear-resisting convenient lubricated again, reduce friction, thereby inner specific (special) requirements alleviated the inertia that deadweight has reduced self main movement.Reasonable by this valve actuating push rod assembly structure of installation evidence, integrated performance index satisfies usage requirement.
