Description
[technical field]
The present invention relates to technical field of planet deceleration, the differential planetary reducer of a kind of digital display non-meshing zone oil temperature.
[background technique]
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 universal planetary (comprising differential planetary) speed reducer exists following problems:
(1) background technique lacks the technological scheme that cleaning is mixed into the iron powder impurity in lubricant oil:
Background technique general cycloid speed reducer sump volume is smaller, lubricants capacity is few, and most of type does not arrange pressure lubrication, thus cannot clear up iron powder impurity in oil, 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, and its result oil product declines, and oil viscosity is thinning, oil film is damaged, oil temperature raises, and causes speed reducer thermal power to decline, and working life shortens.
(2) shortcoming of the structure of background technique universal planetary (comprising differential planetary) speed reducer is:
On-stream; the measuring staff of electromic digit display thermometric instrument is inserted in not oil-feed pond at all; thus existing various type never establishes oil thermometer; if also useless; when wanting to survey oil temperature, also the measuring staff of electromic digit display thermometric instrument can only be placed on the measuring staff appearance of electromic digit display thermometric instrument, way actual in factory is; when hand cannot ride on box body of speed reducer, operator just can shut down.Many times, because operator accurately cannot judge the change of lubricant oil in casing, lead to miss maintenance opportunity and cause and scrap.
(3) background technique General differential planetary speed reducer output shaft sealing surface leakage of oil, main cause is that ventilation cage apertures is too small:
China gear expert and enterprise also think little of the effect of vent hood, and (JB1130-70) that Qin great Tong " Modern mechanical design handbook " (first edition in 2011) rolls up the vent hood structure of 3.15-15 page and exhaust port size and " mechanical design handbook " before 30 years (1980 editions, in, 817 pages) is just the same.The shortcoming of vent hood (JB1130-70) is: exhaust port too small (in case, maximum straight hole aperture is only Φ 20mm, and case aperture that is outer and environmental exposure is then less).When case internal air pressure is greater than air pressure outside case, lubricant oil just leaks from sealing.
[summary of the invention]
The invention provides the differential planetary reducer of a kind of digital display non-meshing zone oil temperature, object is to solve the above-mentioned defect of background technique.

[Advantageous Effects] the present invention can produce following Advantageous Effects known to those skilled in the art:
(1) mazy type vent hood can effectively dust-proof, waterproof, effectively can ensure the balance of body inside and outside air pressure in case leak-stopping is oily;
(2) beneficial effect of meshing zone and jointing place, non-meshing zone drop is: be mixed into the iron filings in lubricant oil in meshing zone, fine impurities can " slip into " in the oil sump of non-meshing zone continually, thus ensure that the turbidity test of meshing zone lubricant oil to the full extent, clean lubricant oil is the key factor that speed reducer runs well;
(3) support top is provided with electromic digit display thermometric instrument, measuring staff injects non-meshing zone oil sump, showing oil temperature fast at any time, when electromic digit display thermometric instrument temperature is when slowly raising, illustrating that oil product declines, oil viscosity is thinning, oil film is damaged, and oil temperature raises, and now operator just can open exhaust port at once, cleaning magnet or cleaning, more oil change, prevent speed reducer from scrapping in time.
