Abstract
The invention discloses a piston rod mechanism, which comprises a piston and a connecting rod. The piston rod is provided with a cylinder. The axis of the cylinder is vertical to the axis of the piston. The cylinder is connected with the piston or the central angle alpha corresponding to a contact surface is smaller than 180 degrees. The small end of the connecting rod is provided with an open tube which is matched with the cylinder. The piston rod mechanism is simple in structure and high in connecting strength, effectively enhances the anti-impact capacity of the piston rod mechanism, and has a wide application prospect.
Description
Technical field
The present invention relates to motor and gas compression field, especially a kind of piston crank mechanism.
Background technique
Piston was realized by wrist pin with being connected all of connecting rod, yet, this Placement must cause the area of the area of the supporting plane between wrist pin and the connecting rod and the supporting plane between wrist pin and the piston limited, under the larger state of pistons work pressure, can't carry due pressure.Therefore, need a kind of novel piston crank mechanism of invention.
Summary of the invention
The invention discloses a kind of piston crank mechanism, increased considerably the area of the supporting plane between connecting rod and the piston, and then improved the transmission capacity of power between piston and the connecting rod, thereby increased considerably the reliability that is connected between piston and the connecting rod, and then made the piston crank mechanism can carry larger active force.
In order to address the above problem, the technological scheme that the present invention proposes is as follows:
A kind of piston crank mechanism, comprise piston and connecting rod, at described piston cylindrical body is set, described cylindrical axis is vertical with the axis of described piston, described cylindrical body be connected with described piston or the corresponding central angle alpha of surface of contact less than 180 °, the microcephaly of described connecting rod is made as open tube, and described open tube matches with described cylindrical body.
Described cylindrical body and described piston one process.
Described cylindrical body is connected through bolt and described piston.
The length of described cylindrical body and described piston surface of contact is not less than 60% of described cylindrical length.
Described cylindrical body and described piston surface of contact are made as cambered surface or plane.
Establish Cooling Holes at described piston.
Establish cooling space at described piston.
Principle of the present invention is: by described cylindrical body being set at described piston and described connecting rod small end being made as open tube, increased the length of the supporting plane between described connecting rod and the described cylindrical body, and then increased the area of supporting plane, and described cylindrical body and described piston one process or are formed by connecting by described bolt, the length of the supporting plane between described cylindrical body and the described piston is all greater than the length of the supporting plane between conventional piston pin and the described piston, therefore, supporting plane between described cylindrical body and the described piston has larger bearing capacity, has finally improved the bearing capacity of piston crank mechanism.
Among the present invention, according to the known technology of related domain, necessary parts, unit or system are set in the place of necessity.
Beneficial effect of the present invention is as follows:
The present invention is simple in structure, join strength is high, has effectively strengthened the impact resistance of piston crank mechanism, has broad application prospects.
