Problems solved by technology

[0003] The crankshaft is subjected to a large gas explosion pressure, the impact of inertial force and centrifugal force during use, which will cause the connecting rod journal to be worn when the connecting rod rotates on the connecting rod journal included in the crankshaft. Severe may lead to the fracture of the crankshaft including the connecting rod journal

Abstract

The invention relates to the field of crankshafts, in particular to a crankshaft. The crankshaft comprises a main shaft, cavities, sliding grooves, oil filling holes, oil filling channels, crankshaftarms, main journals, connecting rod journals, supporting mechanisms, balls, sliding rods, baffle blocks, first springs, pistons, a bearing, oil filling mechanisms, clamping blocks, rotary columns, connecting blocks and second springs. According to the crankshaft, through the use of the supporting mechanisms arranged on the connecting rod journals, when connecting rods rotate on the connecting rodjournals included in the crankshaft, the connecting rods are supported by the supporting mechanisms, and the friction between the connecting rods and the connecting rod journals is reduced; and when the connecting rods rotate to extrude the supporting mechanisms, the supporting mechanisms extrude lubricating oil, so that the lubricating oil can better abut against the oil filling mechanisms, the oil filling mechanisms can better block off the oil filling holes, and in the back-and-forth movement process of the supporting mechanisms in the sliding grooves, the connection parts of the supportingmechanisms and the connecting rods are moistened by the lubricating oil, so that the friction between the connecting rods and the connecting rod journals is reduced advantageously.

Description

technical field [0001] The invention relates to the field of crankshafts, in particular to a crankshaft. Background technique [0002] The crankshaft is the most important component in the engine. It bears the force transmitted by the connecting rod and converts it into torque through the crankshaft output and drives other accessories on the engine to work. The crankshaft is subjected to the joint action of the centrifugal force of the rotating mass, the periodically changing gas inertial force and the reciprocating inertial force, so that the crankshaft is subjected to the bending torsional load. Therefore, the crankshaft is required to have sufficient strength and rigidity, and the surface of the journal needs to be wear-resistant, work evenly, and have good balance. [0003] The crankshaft is subjected to a large gas explosion pressure, the impact of inertial force and centrifugal force during use, which will cause the connecting rod journal to be worn when the connecti...
