High-strength connection rod

Abstract

A disclosed high-strength connection rod comprises a rod body, and a large connection sleeve and a small connection sleeve fixedly arranged at two ends of the rod body; the shaft axes of the large connection sleeve and the small connection sleeve are perpendicular to the length direction of the rod body, the diameter of the large connection sleeve is larger than the diameter of the small connection sleeve, the rod body is connected with the large connection sleeve and the small connection sleeve respectively via an arc large reinforcing rib and an arc small reinforcing rib, the arc part of the large reinforcing rib is matched with the outer circumference of the large connection sleeve, the arc part of the small reinforcing rib is matched with the outer circumference of the small connection sleeve, and the thickness of the large reinforcing rib and the thickness of the small reinforcing rib are both thicker than the thickness of the rod body. By increasing the large reinforcing rib and the small reinforcing rib for increasing the connection strength at two ends of the rod body, the connection area of the rod body with the large connection sleeve and the small connection sleeve is increased, and further the connection strength is increased, so that the connection rod is not easily fractured and the service life is prolonged.

Description

technical field [0001] The invention relates to a high-strength connecting rod. Background technique [0002] The connecting rod is a rod whose two ends are respectively hinged with the driving and driven components to transmit motion and force. For example, in reciprocating piston power machinery and compressors, the connecting rod is used to connect the piston and the crank. The connecting rod is mostly steel, and the cross-section of the main part is mostly round or I-shaped. There are holes at both ends, and bronze bushings or needle bearings are installed in the holes, which are used for loading shaft pins to form a hinge. An important part in an engine such as a ship, it connects the piston and the crankshaft, and its function is to convert the reciprocating motion of the piston into the rotational motion of the crankshaft, and transmit the force acting on the piston to the crankshaft to output power. When the connecting rod is working, in addition to bearing the pres...

Problems solved by technology

It is not only subject to alternating tensile and compressive stress, but also subjected to bending stress. In the connecting rod mechanism, the two ends are respectively hinged with the active and driven components to transmit motion and force. In the prior art, the connection between the large and small connecting sleeve and the rod Insufficient strength, easy to break
