Description
Technical field
The utility model relates to a kind of internal combustion engine part, especially relates to a kind of internal-combustion engine push rod.
Background technique
Internal-combustion engine belongs to a kind of dynamic power machine of burning fossil fuel, from prior art, internal-combustion engine can be divided into petrol engine and diesel engine, petrol engine and the common feature of diesel engine need fuel oil injected gas in-cylinder combustion, gas expansion thus produce thrust and promote the motion of cylinder piston, this straight reciprocating motion is converted to rotary motion and exports by piston again, in fuel oil in the cylinder combustion process, need the fuel oil straying quatity in control cylinder, the injection amount of air and the discharge capacity of waste gas, the control of above-mentioned amount needs to be achieved effective control of cylinder gate.And internal-combustion engine rocking arm belongs to the major way controlling valve, and internal-combustion engine rocking arm is mainly divided into intake rocker and exhaust rocker arm, rocker arm displaces push rod controls valve, because push rod is in the middle of ceaselessly motion, the loss of push rod is very large, and long-time use needs regularly to change.
Model utility content
The purpose of this utility model is to provide a kind of internal-combustion engine push rod, and efficiently solve the problem that internal-combustion engine push rod is easy to loss, the technological scheme of employing is as follows:
A kind of internal-combustion engine push rod, comprise push rod main body, push rod main body lower end is bacterium shape umbrella, is thread section above push rod main body, thread section is connected with adjusting nut, described thread section top is hollow structure, has internal thread in hollow structure, and the thread section of described hollow structure and connecting head bottom spins, described connecting head top is provided with half-spherical cavity, be provided with ball in described half-spherical cavity, the diameter of described ball is less than the diameter of half-spherical cavity, and described ball is connected with rocking arm.
Further, described rocking arm and ball joint are provided with hemisphere bearing shell.
Further, lubricant oil is filled with in described half-spherical cavity.
Further, described half-spherical cavity and hemisphere bearing shell all adopt high carbon steel to make.
After adopting this structure, effectively can solve the problem that internal-combustion engine push rod is easy to loss, maintain easily, and the inner charging-up lubricant oil of cavity, be conducive to the working life extending part.
Accompanying drawing explanation
Fig. 1 is a kind of schematic diagram of internal-combustion engine push rod.
Embodiment
A kind of internal-combustion engine push rod as shown in Figure 1, comprise push rod main body 1, push rod main body 1 lower end is bacterium shape umbrella 2, it is thread section 5 above push rod main body 1, thread section 5 is connected with adjusting nut 6, described thread section 5 top is hollow structure, internal thread is had in hollow structure, the thread section 7 of described hollow structure and connecting head 7 bottom spins, described connecting head 7 top is provided with half-spherical cavity 3, ball 4 is provided with in described half-spherical cavity 3, lubricant oil is filled with in half-spherical cavity 3, the diameter of described ball 4 is less than the diameter of half-spherical cavity 3, described ball 4 is connected with rocking arm 9, rocking arm 9 and ball 4 joint are provided with hemisphere bearing shell 10, described half-spherical cavity 3 and hemisphere bearing shell 10 all adopt high carbon steel to make, wear-resisting durable.
The above, be only embodiment of the present utility model, and those of ordinary skill in the art are in the scope that the utility model discloses, and the change that can expect easily, within the protection domain that all should be encompassed in model utility.
