Description

Dual zone type interlayer casing water-cooled dynamic balancing cycloid reduction case

[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 dynamic balancing cycloid reduction case " (201510078979.9), a kind of dual zone type interlayer casing water-cooled dynamic balancing cycloid reduction case.

[background technique]

Background technique " casing interlayer water-cooled large thermal power dynamic balancing cycloid reduction case " (201510078979.9) is solve the low defect of prior art thermal power, take technological scheme: the 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 water intake of UNICOM's closed interlayer, the side of casing is provided with the water outlet with closed interlayer UNICOM, according to the temperature variation of water, so that temperature control at any time.

Theoretical research shows, the engagement pair in 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 Lubricating Oil Temperature in transmission case:

Background technique carries out temperature control according to the temperature variation of cooling water, change due to water temperature truly can't reflect the change of Lubricating Oil Temperature in gear-box, be directly acquainted with oil temperature, controlling oil temperature is only most important, but background technique comprises prior art, in running, the measuring staff of electromic digit display oil temperature instrument is inserted not to enter at all, thus existingly variously universally cannot arrange oil temperature instrument;

(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.
