Insertion-type vortex air compressor

Abstract

The invention provides an insertion-type vortex air compressor. The insertion-type vortex air compressor comprises a shell and further comprises a static disc, a movable disc, a cross-shaped sliding ring, a crankshaft for driving the movable disc, a movable disc balancing weight, a balance block, a flange plate, a motor connected with the flange plate and a motor main shaft, which are all mounted in the shell. The connection end of the motor main shaft and the crankshaft is hollow so that a cavity is formed; the inner diameter of the cavity is matched with the size of the crankshaft; the crankshaft extends into the motor main shaft; and the coaxiality error of the crankshaft and the motor main shaft is less than 0.015 mm. The insertion-type vortex air compressor has no back cover, end cover and coupling, the size of the flange plate is decreased, and the crankshaft is shortened so that the structure is compact; and the seamless connection is realized by adopting an insertion-type structure, so that the connecting precision is high, the vibration is low, the noise is low, no power is lost, the service life is greatly prolonged, and the working performance is stable.

Description

technical field [0001] The invention relates to a plug-in scroll air compressor, which belongs to the technical field of air compression. Background technique [0002] In the scroll air compressor, especially the direct-connected air compressor, due to the unbalanced inertia formed by the high-speed rotation of the moving plate during the operation of the compressor, in order to make the compressor work more smoothly, the main support of the compressor crankshaft The other end of the bearing is loaded with a counterweight with a larger mass to eliminate the imbalance caused by the moving disc, and a balance mass with a smaller mass is added to the tail of the crankshaft to eliminate the radial torque of the crankshaft and make the machine work in a stable state. It is necessary to increase the crankshaft of the compressor, increase the size of the shell and the flange 23 connected to the motor in the axial direction, and use a larger-sized coupling 24 to connect the compres...

[0002] In the scroll air compressor, especially the direct-connected air compressor, due to the unbalanced inertia formed by the high-speed rotation of the moving plate during the operation of the compressor, in order to make the compressor work more smoothly, the main support of the compressor crankshaft The other end of the bearing is loaded with a counterweight with a larger mass to eliminate the imbalance caused by the moving disc, and a balance mass with a smaller mass is added to the tail of the crankshaft to eliminate the radial torque of the crankshaft and make the machine work in a stable state. It is necessary to increase the crankshaft of the compressor, increase the size of the shell and the flange 23 connected to the motor in the axial direction, and use a larger-sized coupling 24 to connect the compressor with the motor, and at the same time be equipped with an end cover 22 and Back cover 21 (such as figure 2 As shown), the overall structure is not compact enough, resulting in serious power loss, and the vibration and noise during the operation of the equipment are relatively large, which cannot meet the needs of modern industrial production.
