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
The present invention relates to a kind of plug-in type scroll air compressor, belong to technical field of air compression.
Background technique
In scroll type air compressor, particularly in direct-coupled air compressor, due to compressor in the course of the work Moving plate high speed rotating formed uneven inertia, in order to make compressor operating more steady, the larger balancing weight of quality is loaded at the other end of the main spring bearing of compressor crank shaft, eliminate the imbalance that Moving plate brings, the radial torque of equilibrium block elimination bent axle adding a quality less at the afterbody of bent axle makes machine work under plateau, this just needs compressor crank shaft to increase, flange plate 23 size of shell and connection motor is axially increasing growth, and use the shaft joint 24 of large-size that compressor is connected with motor, also be equipped with end cap 22 and bonnet 21(as shown in Figure 2) simultaneously, overall structure is compact not, cause power loss situation serious, vibration in equipment running process, noise is larger, can not meet modern industry Production requirement.
Summary of the invention
For above-mentioned deficiency of the prior art, the invention provides a kind of compact structure, plug-in type scroll air compressor that noise is less.
To achieve these goals, the invention provides following technological scheme: a kind of plug-in type scroll air compressor, comprise housing and be arranged on quiet dish in housing, Moving plate, cross slip-ring, the bent axle of driving Moving plate, Moving plate balancing weight, equilibrium block, flange plate, the motor be connected with flange plate and motor main shaft, the connecting end hollow of described motor main shaft and bent axle forms cavity, the internal diameter of described cavity mates with bent axle size, described bent axle stretches into motor main shaft, and the coaxiality error of described bent axle and motor main shaft is less than 0.015mm.
As preferably, described bent axle is fixed by housing bearing and housing.
As preferably, described bent axle is fixed by flange plate bearing and flange plate.
As preferably, described motor main shaft is fixed by motor output end bearing and motor.
Can be found out by above technological scheme, the present invention without bonnet, end cap, without shaft joint, flange plate size diminishes, bent axle shortens, compact structure, adopts insert structure seamless link, connect precision high, vibrate little, noise is low, unpowered loss, operating life obtains lifting by a relatively large margin, stable work in work.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of direct-coupled air compressor.
Embodiment
The present invention is further described below in conjunction with specific embodiment and accompanying drawing.
A kind of plug-in type scroll air compressor as shown in Figure 1, comprise housing 1 and be arranged on the quiet dish 2 in housing 1, Moving plate 3, cross slip-ring 4, drive the bent axle 5 of Moving plate 2, Moving plate balancing weight 6, equilibrium block 7, flange plate 8, the motor 9 be connected with flange plate 8 and motor main shaft 10, described motor main shaft 10 forms cavity 11 with the connecting end hollow of bent axle 5, the internal diameter of described cavity 11 mates with bent axle 5 size, described bent axle 5 stretches into motor main shaft 10, described bent axle 5 is less than 0.015mm with the coaxiality error of motor main shaft 10, flange plate 8 size diminishes, bent axle 5 shortens, take down bonnet 21, end cap 22, coupling 24, compact structure, because bent axle 5 shortens, the weight of balancing weight 6 and equilibrium block 7 need be increased, reach axial force anomaly weighing apparatus, adopt insert structure seamless link, connect precision high, bent axle 5 supports by two housings bearing 12 simultaneously, flange plate bearing 13, three bearing support structures of motor output end bearing 14, make the higher vibration of stability little, noise is low, unpowered loss, operating life obtains lifting by a relatively large margin, stable work in work, be suitable for applying.
Above the technological scheme that the embodiment of the present invention provides is described in detail, apply specific case herein to set forth the principle of the embodiment of the present invention and mode of execution, the explanation of above embodiment is only applicable to the principle helping to understand the embodiment of the present invention; Meanwhile, for one of ordinary skill in the art, according to the embodiment of the present invention, embodiment and application area all will change, and in sum, this description should not be construed as limitation of the present invention.
