Problems solved by technology

The disadvantage is that after the plunger cylinder is worn, the leakage will affect the reliability of the engine piston return stroke
Due to the large difference in the working pressure of different strokes, it is easy to cause premature wear of the curved grooves corresponding to the power stroke and the compression stroke

Abstract

The invention discloses a double-cylinder internal combustion engine based on a three-cycle curved groove ball bearing, and belongs to the field of internal combustion engines. In order to overcome the defect that a double-cylinder internal combustion engine curved groove of a two-cycle curved groove ball bearing is uneven in abrasion, the invention provides a double-cylinder internal combustion engine based on a three-cycle non-retainer curved groove ball bearing mechanism instead of a crank connecting rod mechanism. According to the double-cylinder internal combustion engine, two inner rings of the three-period non-retainer curved groove ball bearing are fixedly connected, and a gear pair is used for driving a gas distribution mechanism and an ignition (oil injection) mechanism to allow two sets of pistons to conduct opposite reciprocating motion, so that the reciprocating inertia of the two sets of pistons is automatically balanced, and meanwhile, curved grooves of different working pressures of the curved groove ball bearing can be interchanged alternately, thus improving abrasion uniformity. Compared with the prior art, the double-cylinder internal combustion engine based on the three-cycle curved groove ball bearing has the advantages of being 1, simple in motion form and uniform in the abrasion of the curved grooves; 2, small vibration due to the fact that the inertia of the reciprocating motion is automatically counteracted; and 3, low in requirements of part machining and easy to manufacture.

Description

Technical field [0001] The invention relates to a dual-cylinder internal combustion engine device, which belongs to the field of power machinery. Specifically, it relates to a double-cylinder internal combustion engine based on a three-cycle cageless curved groove ball bearing movement form conversion mechanism. Background technique [0002] Since the reciprocating piston internal combustion engine based on the crank connecting rod mechanism was invented, it has been a power machine that burns liquid or gaseous fuel in the cylinder and directly converts the heat energy it releases into mechanical power. Promoting the industrial revolution and the development of transportation technology, it also brought people comfortable and fast travel convenience, and had an important impact on the improvement of people's quality of life. However, the crank structure is complex, the material requirements are high, and the processing difficulty is high. The drawbacks are inevitable. At the sam...
