Abstract
The utility model discloses a valve push rod assembly for an engine. The technical scheme includes that the valve push rod assembly for the engine comprises a push rod pipe. One end of the push rod pipe is welded with a convex ball, and the other end of the push rod pipe is welded with a concave head. The valve push rod assembly for the engine is characterized in that the structure of the valve push rod assembly is improved, two ends of the push rod pipe are welded with the convex ball and the concave head respectively, the valve push rod assembly can rotate while moving by the aid of the special shapes of the convex ball and the concave head, so that grinding uniformity is ensured, and dead weight is effectively reduced by the aid of a hollow structure inside the valve push rod assembly so that inertia of movement is decreased. After installing tests, the valve push rod assembly for the engine has the advantages that the structure is reasonable, and comprehensive indexes meet performance requirements.
Description
Technical field
The utility model relates to technical field of engines, especially relates to a kind of valve actuating push rod assembly that is used on the motor.
Background technique
Valve actuating push rod that engine breathing mechanism generally adopts cam driven opens and closes the inlet and outlet valve through rocking arm, and the valve actuating push rod assembly is important composition in the valve mechanism, and its performance directly influences the working life of whole motor.In the existing technology, the valve actuating push rod assembly has following dual mode to process: first kind, push rod assembly has columned shaft and the steel ball that is arranged on the shaft two ends; Steel ball and shaft adopt commaterial; During use, valve actuating push rod body normal and motor is inconsistent with material with other related components, and the degrees of expansion difference was not closed completely motor inlet and outlet door when hot machine after metal parts was heated; The second way is to adopt former bar cutting to form, serious waste raw material.
Summary of the invention
The purpose of the utility model is to overcome the shortcoming that exists in the existing technology; A kind of valve actuating push rod assembly that welds protruding ball and recessed head at the pusher tube two ends respectively is provided; The technological scheme that adopts is: a kind of motor is used the valve actuating push rod assembly; Comprise pusher tube, it is characterized in that: an end of said pusher tube is welded with protruding ball, and the other end of said pusher tube is welded with recessed head.
The technical characteristics of the utility model also has: in the said pusher tube cavity is arranged.
The technical characteristics of the utility model also has: said pusher tube is steel or aluminum alloy material.
The friendship effect of the utility model is: the utility model has improved the structure of the push rod assembly that pushes; Protruding ball and recessed head have been welded respectively at the two ends of pusher tube; The special shape of protruding ball and recessed head can also carry out rotation when having guaranteed motion, thereby has guaranteed the uniformity of grinding; Thereby the push rod assembly hollow structure inside has effectively alleviated deadweight and has reduced the inertia that moves; Through the installation test, the utlity model has advantage rational in infrastructure, that overall target satisfies performance requirement.
Description of drawings
Accompanying drawing 1 is the utility model structural representation, wherein, the 1st, protruding ball, the 2nd, weld seam I, the 3rd, cavity, the 4th, pusher tube, the 5th, weld seam II, the 6th, recessed head.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the utility model is described.Motor comprises pusher tube 4 with the valve actuating push rod assembly, recessed 6 and protruding ball 1 three parts, and pusher tube 4 is columniform hollow tubulars; The inside of pusher tube 4 is cavitys 3; End in pusher tube 4 is welded with recessed 6, and the other end is welded with protruding ball 1, and weld seam comprises weld seam I 2 and weld seam II 5.Pusher tube 4 can be adopted as steel or aluminum alloy material.
Certainly; Above-mentioned explanation is not the restriction to the utility model; The utility model also be not limited only to above-mentioned for example, variation, remodeling, interpolation or replacement that those skilled in the art are made in the essential scope of the utility model also belong to the protection domain of the utility model.
