Abstract
The utility model relates to an oscillating rotor refrigeration compressor which is provided with a cylinder body (1), a rotor (2), a driving shaft (3), a guide core (4) and an end cover (5), wherein one end of the driving shaft is provided with an oil absorption channel (8) which is communicated with an oil sump, and a branch channel (9) is communicated to the surface of the driving shaft. An oil inlet channel (10) is arranged between the inner wall of the rotor and a hinged hole of the guide core on the rotor, a cavity (11) is communicated with the oil sump outside the cylinder body through an oil inlet channel (12), and the contact plane between the side wall of the guide core and the side wall of a guide groove of the cylinder body is provided with an oil groove (13) which is communicated with the cavity. The structure can ensure good lubrication between the side wall of the guide core and the cylinder body and between the guide core head and the rotor.
Description
The utility model relates to the swing-rotor machine that a kind of mechanical energy with prime mover converts the gas pressure energy to, belongs to compressor field.
We know, the slide plate of rolling rotor type compressor and the friction between the rotor are its intrinsic shortcomings, in recent years the number of patent application of Gong Buing be 89202761.4 ＂ Hinged piston formula compressor ＂ and number of patent application to be 93109921.8 ＂ be transformed into the swing-rotor machine ＂ of fluid pressure energy with mechanical energy, change the relation between slide plate and the rotor into hinging structure and successfully solved sliding friction between slide plate and the rotor.But above-mentioned two kinds of schemes, all fail to solve slide plate or lead core and the lubrication problem of cylinder body, rotor, especially lubricated and between the air inlet side cylinder body guide groove sidewall, during because of compressor operation, the pressurized gas of compression chamber act on slide plate or lead core it is close to air inlet side cylinder body guide groove sidewall, cause friction to increase, influence the efficient and the life-span of compressor.
The purpose of this utility model is to provide a kind of lubricated good swing-rotor type refrigeration compressor of core of leading.
The utility model by cylinder body, rotor, live axle, lead core, end cap is formed, lead core and rotor is hinged, live axle one end has suction passage to be communicated with oil sump, suction passage is led to the eccentric shaft surface by branch road, by centrifugal action lubricant oil is taken to drive shaft surface, its characteristics are: lead core and be communicated with by oil inlet passage with the cavity of cylinder body guide groove formation and the oil sump outside the cylinder body.
The utility model provides following accompanying drawing.
Fig. 1, sectional elevation of the present utility model
Fig. 2, longitudinal section of the present utility model
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
The utility model embodiment, as depicted in figs. 1 and 2, cylinder body (1) two ends, respectively establish an end cap (5), rotor (2) and live axle (3) are positioned at wherein, it is hinged with rotor (2) to lead core (4), lead on the cylinder body (1) of core (4) both sides and establish suction port (6) and relief opening (7), establish suction passage (8) and oil sump connection at live axle (3) one ends, lead to live axle (3) surface from branch road (9) again, by centrifugal action lubricant oil is taken to live axle (3) surface, at the surface of contact lubricate of live axle (3) with rotor (2) inwall and end cap (5) endoporus, leading on rotor (2) inwall and rotor (2) established oil inlet passage (10) between the core hinging hole, establish oil inlet passage (12) from cavity (11) and be communicated with, draw lubricant oil, open oil duct (13) along the contact plane of leading core (4) sidewall and cylinder body (1) guide groove sidewall from cavity (11) side to cavity (11) with oil sump outside the cylinder body (1), oil duct (13) is not communicated with the cylinder chamber, the lubricated better core (4) of leading.
The utility model passes through the foregoing description, core sidewall and cylinder body guide groove sidewall are led in solution, especially lubricating of air inlet side, solved simultaneously and led the lubricated of core print and rotor, reduced the friction of leading core and cylinder body, rotor, can improve the efficient and the life-span of compressor, the possibility that enters industry improves greatly.
Claims (3)
1, a kind of swing-rotor type refrigeration compressor, have cylinder body (1), rotor (2), live axle (3), lead core (4), end cap (5), suction port (6), relief opening (7), lead core (4) and rotor (2) is hinged, and be arranged in cylinder body (1), live axle (3) one ends are established suction passage (8) and are communicated with oil sump, and there is branch road (9) to lead to live axle (3) surface, of the present utility model being characterised in that: to lead core and be communicated with by oil inlet passage (12) with the cavity (11) of cylinder body guide groove formation and the oil sump outside the cylinder body (1).
2, swing-rotor type refrigeration compressor according to claim 1 is characterized in that: open the oil duct (13) that is communicated with cavity (11) at the surface of contact of leading core (4) sidewall and cylinder body (1) guide groove sidewall, oil duct (13) is not communicated with the cylinder chamber.
3, swing-rotor type refrigeration compressor according to claim 1 is characterized in that: oil inlet passage (10) is established in leading between core (4) hinging hole on rotor (2) inwall and the rotor (2).
