Abstract
Casting tubular chilled cast iron tappet end face, comprise the tappet body of integrally casting, tappet body comprises tappet end face and tappet inner chamber, described tappet body outer surface is provided with a plurality of Oil Guide groove, tappet end face is along the several Oil Guide groove of axle center radiation profiles, described Oil Guide groove and Oil Guide groove are connected, and described Oil Guide groove also passes through oil guiding hole UNICOM with tappet inner chamber, and described tappet inner cavity top is arc.
Description
Technical field
The utility model relates to a kind of internal combustion engine part, especially relates to a kind of casting tubular chilled cast iron tappet end face.
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, ceaselessly promotes tappet motion because push rod is in, the loss of tappet 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 casting tubular chilled cast iron tappet end face, and efficiently solve tappet for internal combustion engine processing difficulties, be easy to the problem of loss, the technological scheme of employing is as follows:
Casting tubular chilled cast iron tappet end face, comprise the tappet body of integrally casting, tappet body comprises tappet end face and tappet inner chamber, described tappet body outer surface is provided with a plurality of Oil Guide groove, tappet end face is along the several Oil Guide groove of axle center radiation profiles, described Oil Guide groove and Oil Guide groove are connected, and described Oil Guide groove also passes through oil guiding hole UNICOM with tappet inner chamber, and described tappet inner cavity top is arc.
Further, have the transition of semicircular ring groove between described tappet end face and tappet inner chamber, described semicircular ring groove has been nested with profit malthoid ring.
Further, described Oil Guide groove shapes is sigmoid curve.
After adopting this structure, effectively can solve tappet for internal combustion engine processing difficulties, be easy to the problem of loss, maintain easily, and malthoid circle can trapped grease, oil guiding hole and Oil Guide groove form the closed-loop path of lubricant oil, keep lubrication when engine cold-start, be conducive to the working life extending part.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of casting tubular chilled cast iron tappet end face.
Embodiment
Cast tubular chilled cast iron tappet end face as shown in Figure 1, comprise the tappet body 1 of integrally casting, tappet body 1 comprises tappet end face 3 and tappet inner chamber 2, there is between tappet end face 3 and tappet inner chamber 2 semicircular ring groove 4 transition, described semicircular ring groove 4 has been nested with profit malthoid ring 6, described tappet body 1 outer surface is provided with a plurality of Oil Guide groove 5, tappet end face 3 is the Oil Guide groove 7 of sigmoid curve along the several shape of axle center radiation profiles, described Oil Guide groove 5 is connected with Oil Guide groove 7, described Oil Guide groove 7 also passes through oil guiding hole 8 UNICOM with tappet inner chamber 2, described tappet inner chamber 2 top is arc, due to the integrated casting of whole tappet body 1, processing is simple, durable, malthoid circle 6 can trapped grease, oil guiding hole 8 and Oil Guide groove 5 form the closed-loop path of lubricant oil, lubrication is kept when engine cold-start, be conducive to the working life extending part.
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.
