A, the preparation of regular oil extraction: by sliding rail (13), waste oil collecting box (14) sliding is engaged on bottom plate (12), directly To waste oil collecting box (14) along sliding rail (13) completely into the inside for arriving bearing frame (11)；

B, oil extraction operates: hand extend into the inside of bearing frame (11), after being in contact with drawstring (1714), pulls downward on drawstring (1714), under the action of bracket (1712) and pin shaft (1711), promote interlocking bar (179) to rotate clockwise, utilize lever Principle, the other end of interlocking bar (179) can jack up convergence piece (177) and the drive rod (171) with convergence piece (177) linkage, Since the top of reset spring (175) is located at the lower section of carrying lantern ring (212), when jacking up, carries lantern ring (212) and limit Lantern ring (176) applies active force to reset spring (175) simultaneously, and reset spring (175) is promoted to shorten, during shortening, Convergence piece (177), drive rod (171), closure disk (172) three are formed by linkage structure, integrally move up, and allow and block disk (172) position be not located at the inside of outage (211), and is above the position of outage (211), in this way, outage (211) it is opened, waste oil can be flowed out along the gap between carrying lantern ring (212) and drive rod (171), until waste oil collecting box (14) oil extraction processing is realized in inside；

C, it automatic plugging: after waste oil excludes completely, unclamps drawstring (1714), principle identical with step B, interlocking bar (179) It rotates counterclockwise, restores horizontal position, seal washer (174) and limit lantern ring (176) stop applying reset spring (175) Squeezing action power, reset spring (175) restores initial length, but is still in confined state, convergence piece (177), drive rod (171) and closure disk (172) integrally moves down, and allows and blocks the inside that disk (172) are located at outage (211) again, seal washer (174) it is located at and blocks between disk (172) and carrying lantern ring (212), cooperate the extruding force of spring, reaches automatic plugging and sealing Purpose；

S3, oil extraction post-processing: with the principle of step A, by sliding rail (13) by waste oil collecting box (14) from bearing frame (11) Inside pull out and it is disassembled from sliding rail (13), be filtered processing by filtration zone；

S4, the new grease of injection: injecting new lubricant grease to the inside of deceleration mechanism (2), and synchronize the principle of rapid S2, into And secondary debugging；

S5, come into operation: the secondary debugging in step S4 in the process of running, when no bad phenomenon, can come into operation.
