Description
[technical field]
The present invention relates to cycloid reduction technical field, is the improvement of application for a patent for invention " casing interlayer water-cooled large thermal power few teeth difference speed reducer " (201510078890.2), the air-cooled few teeth difference speed reducer of a kind of dual zone type interlayer casing.
[background technique]
Background technique " the air-cooled large thermal power few teeth difference speed reducer of casing interlayer " (201510078890.2) is solve the low defect of prior art thermal power, the technological scheme taked is: " outer wall of the inwall of casing and inner cylinder and nose circle lid attachments encloses to connect and forms airtight interlayer; casing top is provided with the suction port of UNICOM's closed interlayer; the side of casing is provided with the air outlet door with closed interlayer UNICOM; with the temperature rise of driving component in Air flow built-in cylinder, technique effect be that structure is simple, cost is low and temperature control reliable "
Theoretical research shows, in gear transmission, occurs that flank of tooth loss is inevitable:
Upper 103 pages of (a) Shanghai Machinery College " Fundamentals of Machine Design ": " gear transmission equipment is pulled down after using a period of time can find that wear trace appears in tooth surface; lubricating under poor or the impure condition of lubricant oil especially; wear phenomenon is more obvious; gear teeth root weares and teares, and seriously, comparatively gearwheel is serious again in small gear wearing and tearing at comparatively top.Wearing and tearing cause owing to having active force and relative sliding between surface of contact.There is relative sliding length Δ S between flank profil, shown that flank profil will be worn and torn.”
(b) Zhu Xiaolu " Gear Transmission Design handbook " 94 pages: in power gear transmission, tooth surface due to skimming wear, burn into overheated etc., thus occur that flank of tooth loss is inevitable.
Research finds, background technique exists following problems:
(1) background technique lacks the technological scheme that cleaning is mixed into the iron powder impurity in lubricant oil:
Obviously, background technique sump volume than former technology without little during interlayer, therefore lubricants capacity also lacks, and when being mixed into the iron powder impurity in lubricant oil and slowly becoming many, background technique is again without the technological scheme reducing iron powder impurity, its result oil product declines, oil temperature raises, and oil viscosity is thinning, and oil film is damaged, cause speed reducer thermal power to decline, working life shortens;
(2) during running, cannot pick up and look into oil temperature in transmission case: the change of water or wind (air-flow) temperature truly can't reflect the change of Lubricating Oil Temperature in gear-box, be directly acquainted with and control oil temperature and be only most important, but background technique comprises prior art, in running, the measuring staff of electromic digit display thermometric instrument is inserted not to enter at all, thus existingly variously universally never establishes oil thermometer;
(3) in transmission case, the quality comparison of lubricant oil and oil reserve are not easily picked up and are looked into, and refuel also inconvenient.
