Description
Technical field
The utility model relates to a kind of compressor, is specifically related to a kind of oil spout scroll air compressor optimizing rack construction.
Background technique
Scroll air compressor is high with its efficiency, noise is low, volume is little, be conducive to the advantages such as energy-conservation and protection of the environment and be widely used in the industries such as industry, agricultural, communications and transportation needing compressed-air actuated occasion.Scroll air compressor mainly runs part whirlpool dish and only has engagement, and do not produce wearing and tearing, thus the life-span is longer than piston type, screw compressor, is pneumatic machinery ideal power source.In scroll air compressor, main operation part scroll is divided into orbiter and fixed scroll, vortex sheet is established in orbiter and fixed scroll, usually, be bonded to each other by orbiter and fixed scroll and form compression chamber, when orbiter does translation by bent axle drive along certain circular path, orbiter vortex sheet moves relative to fixed scroll vortex sheet, namely the compression chamber formed by both moves and changes its volume, thus carries out sucking, compresses, discharges, and completes compressed-air actuated process.
Current oil spout scroll air compressor supplementary bearing is positioned in rear bay, and shaft seal is positioned in bonnet, when shaft seal occurs to leak, changes shaft seal by changing rear case component.Because rear bay and bonnet need separate machined, cause the coaxality of assembling rear shaft seal and bearing to decline, easily cause shaft seal leakage of oil.Further, need between rear bay and bonnet use seal ring and screw sealing and fastening, cause complex structure, fabricating cost is high, and easily leaks.
Model utility content
The purpose of this utility model is, has above-mentioned technical problem to solve existing compressor, provides a kind of oil spout scroll air compressor adopting lid rear bay structure.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of oil spout scroll air compressor adopting lid rear bay structure, comprise fixed scroll, orbiter, cross slip-ring, bent axle, frame, main equilibrium block, belt pulley, capacity eccentric bearing, main bearing, supplementary bearing, described orbiter engages with fixed scroll and forms compression chamber, the eccentric part of bent axle is arranged on the wheel hub of orbiter, by capacity eccentric bearing by bent axle and orbiter fixed installation, described frame includes forebay and rear bay, described rear bay is the lid on forebay, rear bay and forebay are sealed and matched, the diameter bore of fixed installation bent axle is provided with in rear bay, main shaft envelope is installed in described diameter bore from the inside to the outside, countershaft envelope and supplementary bearing, gap is left between this main shaft envelope and countershaft envelope, the axis body of described bent axle is arranged on forebay with main bearing, is arranged on rear bay with supplementary bearing, and one end of bent axle passes diameter bore and is fixed in frame by bent axle.
The purpose of this utility model can also be achieved through the following technical solutions:
Further, described fixed scroll is provided with an Aspirating valves, Aspirating valves is provided with an inlet port, and the interstitial site on described diameter bore between main shaft envelope and countershaft envelope is provided with an oil suction joint, and this oil suction joint is connected with the inlet port of Aspirating valves by a connecting tube.
Further, seam face is adopted to be sealed and matched between described forebay and rear bay.
The beneficial effects of the utility model:
1, frame of the present utility model includes forebay and rear bay, described rear bay is the lid on forebay, rear bay and forebay are sealed and matched, the diameter bore of fixed installation bent axle is provided with in rear bay, described main shaft envelope, countershaft envelope and supplementary bearing are arranged in diameter bore from the inside to the outside, leave gap between this main shaft envelope and countershaft envelope; The axis body of described bent axle is arranged on forebay with main bearing, is arranged on rear bay with supplementary bearing, and one end of bent axle passes diameter bore and is fixed in frame by bent axle.Thus, rear bay is installed the bearing chamber of supplementary bearing, the shaft seal chamber installing shaft seal and seam face and all can a fine finishing be completed, namely the diameter bore of rear bay can machine by clamped one time, therefore can effectively improve shaft seal and bearing install after coaxality, reduce the probability of shaft sealing leakage, improve the reliability of compressor.Meanwhile, the use of seal ring and fastening piece can be reduced, reduce the cost of compressor, improve product competitive ability.
2, fixed scroll of the present utility model is provided with an Aspirating valves, Aspirating valves is provided with an inlet port, interstitial site on described diameter bore between main shaft envelope and countershaft envelope is provided with an oil suction joint, and this oil suction joint is connected with the inlet port of Aspirating valves by a connecting tube.When leaking appears in main shaft envelope, lubricant oil flows in the gap between main shaft envelope and countershaft envelope, be inhaled in Aspirating valves through oil suction joint and connecting tube, reenter compressor inside, the lubricant oil of leakage and external isolation come by countershaft envelope, make the lubricant oil of leakage in compressor inner loop, therefore, when scroll air compressor is operated, effectively prevent oil leakage phenomenon, run more reliable and more stable.
