Description
Technical field
The utility model relates to a kind of internal combustion engine part, especially relates to a kind of wear-proof valve rocker.
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, and due to the miniaturization of internal-combustion engine, on internal-combustion engine, the space of mounting parts is more and more less, more and more higher to the requirement of strength of rocking arm.
Model utility content
The purpose of this utility model is to provide a kind of wear-proof valve rocker, efficiently solves the wear problem of intake rocker and exhaust rocker arm, and the technological scheme of employing is as follows:
A kind of wear-proof valve rocker, comprise middle bearing shell, middle bearing shell one end connects the axis of rolling by curved boom, the middle bearing shell the other end connects adjusting key by straight-arm, described middle bearing shell, straight-arm, curved boom, adjusting key and the axis of rolling are that spheroidal graphite cast iron is one-body molded, a roller is connected by locking screw stud shaft, UNICOM's oil leab between roller and the axis of rolling in the middle of the described axis of rolling.
Further, the inwall of described middle bearing shell is provided with multiple oil groove.
Further, the hardness of described roller is less than the hardness of the axis of rolling.
Further, described lock bolt with between roller for ball bearing is connected.
After adopting this structure, effectively can solve the wear problem of rocking arm, reduce the size of rocking arm, solve Engine Downsizing problem.
Accompanying drawing explanation
Fig. 1 is a kind of schematic diagram of wear-proof valve rocker.
Embodiment
A kind of wear-proof valve rocker as shown in Figure 1, comprise middle bearing shell 1, middle bearing shell 1 one end connects the axis of rolling 3 by curved boom 5, middle bearing shell 1 the other end connects adjusting key 2 by straight-arm 4, described middle bearing shell 1, straight-arm 4, curved boom 5, adjusting key 2 and the axis of rolling 3 are that spheroidal graphite cast iron is one-body molded, the inwall 6 of middle bearing shell 1 is provided with multiple oil groove 9, a roller 7 is connected by lock bolt 8 axle in the middle of the described axis of rolling 3, for ball bearing is connected between lock bolt 8 with roller 7, the hardness of roller 7 is less than the hardness of the axis of rolling 3, between roller 7 and the axis of rolling 3, UNICOM's oil leab 10 is for lubricating roller 7 of lowering the temperature.
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.
