Abstract

The utility model relates to a reciprocating piston compressor with a bent axle and an active wheel, which comprises a machine body, a bent axle, a flywheel, a main bearing, cylinders and a balance block. The utility model is characterized in that both sides of the machine body are provided with two cylinders respectively. The four-stage compression is in H-shaped arrangement. The inner pistons of the machine body are arranged in parallel. Both ends of the piston are provided with a piston head, and the middle part of the piston is connected with a flat leading block. The centre of the leading block is provided with a circular hole in which a sliding bearing is arranged, and the sliding bearing is connected with a sliding friction pair of the active wheel. The active wheel is provided with an eccentric hole in which a sliding bearing is arranged. The bent axle is connected with the sliding friction pair in the sliding bearing, and the bent axle and the piston are in H-shaped arrangement. The piston is connected with the sliding friction pair along the slideway of the machine body. The bent axle is connected with the sliding friction pair in the main bearing.

Description

Bent axle active wheel Reciprocting piston compressor

Technical field

The utility model relates to a kind of Reciprocting piston compressor, particularly place's bent axle active wheel Reciprocting piston compressor.

Background technique

Be acquisition pressurized air, thereby compressor occurred, traditional compressor moves piston by linkage mechanism in cylinder, pressurized air, and its volume is big, is difficult to balance when complex structure, work, and vibration is big.In disclosed in ZL85200336 " crankshaft circalar slide block reciprocating piston compressor ", adopt rolling friction pair and gear pair to make crank round slider rotatablely moving of bent axle be become the to-and-fro motion of piston, pressurized air, its structure more complicated, vibration is big during work, noise is high, the many volumes of part are big, and power consumption is big, inefficiency.

Summary of the invention

The purpose of this utility model is to design that a kind of structure is comparatively simple, part is few, volume is little, it is low to vibrate little noise during work, and stable working reduces power consumption, the bent axle active wheel Reciprocting piston compressor of increasing work efficiency.

The purpose of this utility model is to realize like this, a kind of bent axle active wheel Reciprocting piston compressor, include fuselage, bent axle, flywheel, main bearing, cylinder, equilibrium block, it is characterized in that each row has two cylinders one in the both sides of fuselage, three-stage cylinder and two, the level Four cylinder, the level Four compression is the setting of H type, fuselage interior one, second piston and three, the level Four piston is arranged in parallel, the piston two ends are equipped with piston head, the middle part is connected by the flat guide slide block, there is circular hole in guide runner central authorities, sliding bearing is housed in the circular hole, there is the active wheel sliding friction pair to connect in the sliding bearing, active wheel is provided with the eccentric opening that throw of eccentric equates with the crankshaft eccentric distance, sliding bearing is arranged in the eccentric opening, and bent axle sliding friction pair in sliding bearing connects, and bent axle and piston are the setting of H type, piston is that sliding friction pair connects along the slideway of fuselage, and bent axle sliding friction pair in main bearing connects.

The utility model is owing to respectively arrange two cylinders in the fuselage both sides, be the H type and arrange that cylinders at different levels are absolute construction, therefore be easy to manufacturing, easy for assembly, disassembly and maintenance, piston is along the to-and-fro motion of fuselage slideway, between piston and active wheel, between active wheel and bent axle and the friction pair that rotatablely moves between bent axle and main bearing all to have adopted sliding bearing be sliding friction pair, reduced volume, noise and vibration have been reduced, it is few that friction pair quantity is lost power consumption less, the efficient height, and lubricating oil consumption is few.Driving active wheel by the crankshaft rotating motion rotates, piston is done reciprocating linear motion by the simple harmonic quantity rule along the fuselage slideway, the gas that the to-and-fro motion of piston will suck cylinder compresses step by step, finally reach desired gas pressure, and piston is easy to balance by the simple harmonic quantity rule inertial force that produces that does reciprocating linear motion, thus the compressor motion steadily, vibration is little, noise is low, simple in structure.
