Abstract
The utility model provides a high -power diesel engine's valve push rod, including bulb, ball seat, be equipped with the connecting rod between bulb and the ball seat, bulb, connecting rod, ball seat become one through the butt welding, and bulb and ball seat are the steel ball material respectively, and the connecting rod is seamless steel pipe. Use high -power diesel engine's valve push rod, adopt the butt welding structure, welding strength is high, toughness is good, steel ball and ball seat are difficult to drop, steel pipe intensity height adapts to high -power diesel engine valve push rod structure simultaneously.
Description
Technical field
The utility model relates to a kind of valve actuating push rod, especially a kind of valve actuating push rod of high output diesel engine.
Background technique
The function of engine valve actuating mechanism is job order according to motor and working procedure, time opening and close intake valve and exhaust valve, makes inflammable mixture or air enter cylinder, and waste gas is discharged in cylinder, realize gas exchange process.Distribution device is made up of timing gear, camshaft, push rod (above having adjusting nut), rocking arm bridge, rocking arm, valve, valve return and valve seat.When camshaft rotates, because the eccentric wheel on camshaft distributes in out of phase, camshaft promotes push rod, push rod promotes one end, makes the rocking arm the other end depress valve and valve return, valve is opened, oil cylinder air inlet or give vent to anger, when push rod leaves rocking arm, valve resets under return spring effect, valve-closing.
The valve actuating push rod of current domestic production, sale generally adopts the conventional machining process of side welding and integrated type cold-heading molding.Its feature: (1) adopts side welding, and bulb, ball bowl and steel-pipe welding intensity are not high, and steel ball and bowl easily come off, and are not suitable with high output diesel engine valve actuating push rod structure.(2) adopt the processing mode of overall cold-heading molding, although reliable product quality, its processing cost is high, and simultaneously because product steel pipe adopts entity, product weight weight, is not suitable for available engine lightweight requirements.
Summary of the invention
The purpose of this utility model is to provide a kind of valve actuating push rod of high output diesel engine, can improve intensity and the abrasion resistance of push rod, improve its working life, meets the light-weighted requirement of vehicle.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: a kind of valve actuating push rod of high output diesel engine, comprise bulb, ball seat, connecting rod is provided with between bulb and ball seat, it is characterized in that: described bulb, connecting rod, ball seat become to be integrated by butt welding, bulb and ball seat are respectively steel ball material, and connecting rod is seamless steel pipe.
Improvement to technique scheme: described steel ball material is formed with carburized case by Carburization Treatment on surface.
Beneficial effect:
Use the valve actuating push rod of high output diesel engine described in the utility model, adopt butt welding structure, weld strength is high, good toughness, and steel ball and ball seat are not easy to come off, and steel strength is high simultaneously, adapts to high output diesel engine valve actuating push rod structure; The connecting rod of product adopts seamless steel pipe, because seamless steel pipe is hollow, makes the lightweight of product, is particularly suitable for Modern Engine lightweight requirements; Bulb and ball seat are respectively steel ball material, and steel ball material is formed with carburized case by Carburization Treatment on surface, improve the abrasion resistance of product, effectively improve the working life of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
The valve actuating push rod of a kind of high output diesel engine of the utility model as shown in Figure 1, comprise bulb 1, ball seat 2, connecting rod 3 is provided with between bulb 1 and ball seat 2, described bulb 1, connecting rod 3, ball seat 2 become to be integrated by butt welding, bulb 1 and ball seat 2 are respectively steel ball material, steel ball material is formed with carburized case by Carburization Treatment on surface, and connecting rod 3 is seamless steel pipe.
Claims (2)
