The beneficial effect that the present invention adopts single-stage cycloidal to replace three stage planetary reduction is shortening axial dimension, structure is simple, cost reduces.Theoretical foundation is: " gear handbook " (on) 8-3 page: cycloid η=0.93 ~ 0.95; Zhu Xiaolu " Gear Transmission Design handbook " 6 pages, " gear handbook " upper 1-12 page: cycloid efficiency eta=0.9 ~ 0.98 ≈ 0.94.
For realizing the object of patent of the present invention, adopt following technological scheme:
(technological scheme one)
The bottom of large end cap is provided with butterfly valve, butterfly valve comprises valve rod and circular channel, valve rod connects circular butterfly plate, circular butterfly plate can rotate in circular channel, the end of circular channel connects detachable lubricating cup, be magnetic in lubricating cup thing, butterfly valve makes open-shut device with circular butterfly plate and rotate with valve rod to open, close and regulate a kind of valve of fluid passage, the butterfly plate of butterfly valve is installed on the diametric(al) of pipeline, in butterfly valve body cylindrical channel, disc butterfly plate rotates around valve rod axis, angle of swing is 0 ° ~ 90 °, when rotating to 90 °, valve is standard-sized sheet then, thus can regularly the irony powder be mixed in Run lubricating oil be taken out: rotation valve rod-circular butterfly plate closes non-meshing zone oil sump circular channel, pull down lubricating cup, pour out the irony powder of Magnetic Materials absorption in lubricating cup,
(technological scheme two)
Output shaft the second bearing is bearing in support endoporus, output shaft end connection for transmission gear, first and second identical with its both sides of driving gear shunts gears meshing, first and second shunting gear engages with the large-scale ring gear of shield machine circular cutting disk, make speed reducer bearing power increase one times, thus can reduce by half assembling, save the foreign exchange expenditure of a considerable third-level planetary reduction gear, first shunting gear the 3rd bearing is bearing in the first axle, first shunting gear the 4th bearing supports on the second mandrel, and two axles are fastened on the end face of support output terminal.
The theoretical foundation of the technical solution adopted in the present invention is as follows:
(A) 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.
(B) butterfly valve makes open-shut device with circular butterfly plate and rotates a kind of valve opening, cut out and regulate fluid passage with valve rod.The butterfly plate of butterfly valve is installed on the diametric(al) of pipeline.In butterfly valve body cylindrical channel, disc butterfly plate rotates around valve rod axis, and angle of swing is 0 ° ~ 90 °, and when rotating to 90 °, valve is standard-sized sheet then.
Advantageous Effects
