Description
[technical field]
The present invention relates to aerial cableway speed reducer technical field, a kind of aerial cableway self-retention cycloidal reducer.
[background technique]
Aerial cableway is widely used in Mine haul and perilous peak tourist attraction, and speed reducer is very important parts in aerial cableway, and high reliability speed reducer can protect the safety of thousands of people's life and property.Background technique has three kinds:
(1) the empty cable reducer (rolling up 4.16-235 page see becoming large elder generation " mechanical design handbook ") of STJ type frame: STJ type speed reducer is combined by arc bevel gear drive and cylindrical planetary gear speed reducer, be three grades of vertical type transmissions, STJ type is mainly applicable to aerial cableway, also can be used for the vertical type transmission of other machinery, particularly relatively high power.Shortcoming is: complex structure, maintenance inconvenience, bevel gear pair and planetary reduction gear parts the valency high 2-2.5 of cycloid (be doubly) and reliability unstable, because involute tooth root is stress raiser, when carburizing and quenching and grinding, very easily occur that microcrack causes break of gear tooth;
(2) two enter formula aerial cableway planetary reduction gear (ZL200520111177.5): dual-motor input, arc bevel gear-three grades, cylinder planet vertical type transmission, shortcoming is: inventor thinks that retarder can not quit work when wherein a motor breaks down, this can only when load be less than specified 50%, retarder ability normal rotation, otherwise single motor cannot drive retarder at all.Therefore can conclude that dual-motor input is not creative, not have use value.Other shortcoming is identical with STJ;
(3) HZL planetary-gear speed reducer (JB/T8712-1998, JB/T7344-1994): the improvement being existing involute less tooth difference: ring gear exports; The pin of pin axle type output mechanism changes double-eccentric shaft into, four selfaligning roller bearings axle are equipped with, this is called rolling star-wheel by inventor, be supported in two-side supporting dish and two panels planet wheel pin-and-hole in four bearings respectively, because planet wheel is very wide, therefore in each pin-and-hole, add one and be called auxiliary bearing.Shortcoming is: complex structure, keep in repair extremely inconvenient, and star reduction part device cost ratio planetary reducer will exceed 20-30%.The aerial cableway HZL planetary-gear speed reducer of certain company can be found on the net: rated power 80kW, input speed 1500rpm, allowable torque: 80000N.m, work as present value: 200000 yuan/platform.
[summary of the invention]
The object of the invention provide structure simple, check, repair the vertical single-stage cycloid convenient, price is low, efficiency is identical and reliable and replace background technique, a kind of aerial cableway self-retention cycloidal reducer.
Think according to Chinese cableway association paper " analyzing failure cause seeks governance way ": the main problem of vertical cableway retarder is leakage of oil; Inner Mongol Xinghua enginerring works, Mutianyu, Beijing ... " exploration of import passenger aerial ropeway speed reducer Home-produced Reconstruction " point out: the subject matter of cable reducer is heating, leakage of oil; China's cableway 2002.9 " lubrication of cable way driving machine tool speed reducer of having a talk " proposes: can cable reducer safe operation is depended on the change of oil product and oil mass in Timeliness coverage speed reducer.
(A) be that the two mechanical efficiency is identical by the theoretical foundation that single-stage cycloidal deceleration replacement three grades is slowed down: " 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; Its practicability (value) is: structure is simple, cost is about at half.
Technological scheme: the toroidal surface of (1) vertical support central flange connects a dome and is used for covering bearing, prevent lubricant oil from entering bearing and spill from oil sealing; (2) partly burying toothing makes needle pin have very high bending force; (3) capacity eccentric bearing outer collar rib makes cycloid wheel can locate in the vertical direction, avoids rubbing between cycloid wheel and spacer ring, causes oil temperature to raise; (4) vertical support is equipped with dipstick, is convenient to check oil product, oil mass fast; (5) abat-vent of pin wheel housing (29) top dress exceeds 50 ~ 60mm, and abat-vent main exhaust φ 25 ~ φ 35mm, avoids leakage of oil to ensure speed reducer inner chamber oil pressure equal with environment;
(B) single-stage cycloidal retarding braking technological scheme: two groups of steel ball V-type slot devices in brake component are that steel ball V-type groove automatic pressurizing device improves (seeing Ruan Zhongtang " mechanical stepless transmission " 90 pages): first group is made up of the steel ball between active V-type slotted disk, the driven V-type slotted disk in telophragma side and two V-type groove faces, and telophragma connects with cone dish; Second group is made up of the steel ball in the middle of telophragma opposite side initiatively V-type slotted disk, the second driven V-type slotted disk and two V-type groove faces.Working principle: during energising, first group of active V-type groove face produces positive pressure to steel ball, and its axial thrust load promotes the driven V-type slotted disk of telophragma makes friction pair be separated, and braking moment disappears, and its circumferential component drives the output shaft work done connected with second group of driven V-type slotted disk; During power-off, input shaft stop, resisting moment makes the second driven V-type groove face produce positive pressure to steel ball, and its axial thrust load makes friction pair compress, and braking moment will muchly have much.
[beneficial effect], according to background technique, its creativeness is embodied in:
(1) braking moment increases with resisting moment and automatically increases;
(2) cyclo drive steadily, never broken teeth high-reliability, pin-cycloid wheel for roll engagement, long service life;
(3) rotating mass on input shaft is in static balancing, dynamic equilibrium state, makes transmission more steady;
(4) single-stage cycloidal cableway retarder of the present invention and background technique: STJ type, HZL type compare and see the following form:
