Background

An Engine (Engine) is a machine capable of converting other forms of energy into mechanical energy, including, for example, internal combustion engines (reciprocating piston engines), external combustion engines (stirling engines, steam engines, etc.), jet engines, electric motors, etc. Such as internal combustion engines, typically convert chemical energy into mechanical energy. The engine is suitable for a power generation device, and can also refer to the whole machine (such as a gasoline engine and an aircraft engine) comprising the power device. Engines were first introduced in the uk, so the engine concept is also derived from english, which is meant to mean "power generating machinery", while external combustion engines, i.e. combustion of its fuel outside the engine, are also known as stirling engines. The engine converts the heat energy generated by the combustion into kinetic energy, the watt-improved steam engine is a typical external combustion engine, when a large amount of coal is combusted to generate heat energy to heat water into a large amount of water vapor, high pressure is generated, and then the high pressure pushes the machine to do work, so that the conversion of the heat energy into the kinetic energy is completed.

SUMMERY OF THE UTILITY MODEL

The utility model provides a not enough to prior art, the utility model provides an engine crankshaft machine case possesses the heat dissipation of being convenient for and improves advantages such as box intensity, has solved the current poor and relatively poor problem of box intensity of engine radiating effect.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an engine crankshaft machine case, includes the base, the top fixed mounting of base has the box, the thermovent has been seted up to the bottom of box, the turbine shaft hole has been seted up at the middle part of box, one side fixedly connected with piston hole of box, one side fixed mounting of box has the deep bead that is located piston hole both sides.

Furthermore, the bottom of the box body and the inner wall of the top of the heat dissipation opening are provided with heat dissipation holes.

Furthermore, the deep bead has two, and all is provided with the heat dissipation grid between the inside of thermovent and two deep beads, and the heat dissipation grid that is located between two deep beads contacts with one side outer wall of deep bead each other.

Further, the piston hole is located between the two wind shields.

Furthermore, limiting holes positioned around the turbine shaft hole are fixedly arranged on the outer walls of the front side and the back side of the box body.

The utility model has the advantages that:

this engine crankshaft machine case, through the base, the box, the thermovent, the turbine shaft hole, the joint setting of piston hole and deep bead, increase the deep bead about the heat dissipation grid around the piston hole, make it form the wind channel with original grid, the wind channel is compared with original grid, the heat that the engine turbine rotated the production can be better with pressure distribute away, louvre and heat dissipation grid have also been increased to the bottom, and simultaneously, the deep bead of upper and lower face and the support part of extension, can effectively strengthen the intensity of box, the stability of box is kept in cylinder piston motion.
