Embodiment
Fig. 1 represents the overall structure figure of refrigeration compressor of the present invention, and Fig. 2 represents the structural representation of the bent axle of refrigeration compressor of the present invention.
As shown in Figure 1, refrigeration compressor of the present invention comprises: the valve block assembly of upper cylinder cover 2, cylinder 3, slide plate, rolling piston, bent axle 8, lower cylinder head 7, lower cylinder head, Sealing, exhaust catch, wherein upper cylinder cover 2 is provided with bearing hole, cylinder 3 there is the vane slot that can hold slide plate, lower cylinder head 7 is also provided with bearing hole, and bent axle 8 and upper cylinder cover 2, cylinder 3, rolling piston, slide plate and miscellaneous part fit together.
As illustrated in fig. 1 and 2, bent axle 8 has center hole, this center hole runs through the main journal of bent axle 8, the first oilhole 11 is had in first annular groove 15 of one end that bent axle 8 up and down cylinder head 7 connects, the cam 10 of bent axle 8 has the second oilhole 12 in rolling piston and cam 10 place of being nested together, in the second annular groove 16 be connected with upper cylinder cover bearing, has the 3rd oilhole 13.
In the prior art; the bent axle of compressor only has oilhole; because the oil sump of upper bearing (metal) distance bottom of shell is longer; therefore the helical blade of center hole is only relied on cannot to lubricate completely upper bearing (metal); thus the situation often causing the pump housing stuck occurs, and the shutdown of whole compressor may be caused time serious to scrap.
As shown in Figure 2, according to an embodiment of the invention, in order to overcome above-mentioned defect of the prior art, the outer surface of the present invention on the main journal be connected with upper bearing (metal) offers helical oil groove 14.
Above-mentioned mode of execution of the present invention makes lubricant oil enter helical oil groove 14, by the rotation of bent axle and then lubricate upper bearing (metal), thus upper bearing (metal) can be arrived by lubrication fully.
According to an embodiment of the invention, described helical oil groove 14 arranges around the main journal of bent axle 8, by the rotation of bent axle 8 and then progressively can be risen by arranging after lubricant oil enters helical oil groove 14 of said structure, and lubricant oil 9 got rid of each position to upper bearing (metal) by the rotation of bent axle 8 in the process, thus upper bearing (metal) is lubricated fully
According to an embodiment of the invention, one end (one end bottom compressor) of helical oil groove 14 connects with the second annular groove 16 of the 3rd oilhole 13, thus make lubricant oil can enter the second annular groove by the 3rd oilhole 13, and then enter in helical oil groove 14
According to an embodiment of the invention, the other end (one end near air compressor motor portion) of helical oil groove 14 connects with the 3rd annular groove 17 on main journal, described 3rd annular groove 17 is positioned at the connecting end near bent axle and motor, thus make lubricant oil can throw away bent axle by the 3rd annular groove 17, and then be recycled in the lubricating oil bath bottom compressor.
Why lubricant oil can enter the oilhole in bent axle by oil sump and then further rise, be filled with pressurized gas because of in compressor in the course of the work casing, lubricant oil 9 produces hydraulic pressure by the pressure of gas exerts, and then by the center hole of bent axle 8, lubricant oil 9 is risen to the second annular groove 16 place of the 3rd oilhole 13, pass through embodiments of the present invention, connect with the second annular groove 16 of the 3rd oilhole 13 and around the helical oil groove 14 on main journal, lubricant oil is accelerated thus brings up to higher height for 9 two time, whole upper bearing (metal) running element is made to obtain more sufficient lubrication.
Above-described embodiment not limits the invention, and those skilled in the art can design alternative embodiment when not departing from claims scope.In the claims, any reference symbol between bracket should be configured to limitations on claims.Word " comprises " not to be got rid of existence and does not arrange element in the claims or step.
