Description
[technical field]
The present invention relates to aerial cableway deceleration device technical field, a kind of aerial cableway self-retention cycloidal reducer.
[background technology]
Aerial cableway is widely used in Mine haul and perilous peak tourist attraction, and deceleration device is particularly important parts in aerial cableway, and high reliability deceleration device can protect the safety of thousands of people's life and property. Background technology has three kinds:
(1) STJ type frame sky cable reducer (rolling up 4.16-235 page see becoming big first " mechanical design handbook "): STJ type speed reducer is combined by arc Bevel Gear Transmission and cylindrical planetary gear reductor, it is three grades of vertical type transmissions, STJ type is primarily adapted for use in aerial cableway, can also be used for the vertical type transmission of other plant equipment, particularly relatively high power. Shortcoming is: structure is complicated, maintenance inconvenience, bevel gear pair is unstable with planetary reduction gear parts valency high (being 2-2.5 times of cycloid) and reliability, because involute tooth root is stress raiser, when carburizing and quenching is with grinding, very easily occur that microcrack causes break of gear tooth;
(2) double; two enter formula aerial cableway planetary reducer (ZL200520111177.5): bi-motor input, arc bevel gear-three grades of cylinder planet vertical type transmission, shortcoming is: inventor thinks that decelerator will not quit work when wherein a motor breaks down, this can only when load be less than specified 50%, decelerator ability normal rotation, otherwise, single motor cannot drive decelerator at all.It can be concluded that bi-motor input is not creative, do not have practical value. Other shortcoming is identical with STJ;
(3) HZL planetary-gear speed reducer (JB/T8712-1998, JB/T7344-1994): be the improvement of existing involute less tooth difference: ring gear exports; The pin of pin type output mechanism changes double-eccentric shaft into, equipped with four self-aligning roller bearings on axle, this is called rolling star-wheel by inventor, four bearings are supported on respectively in two-side supporting dish and two panels planetary gear pin-and-hole, owing to planetary gear is very wide, therefore in each pin-and-hole, add one and be called auxiliary bearing. Shortcoming is: structure is complicated, it is extremely inconvenient to keep in repair, and star reduction part device price to exceed 20-30% than planetary reduction gear. 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 vertical single-stage cycloid that the object of the invention offer simple in construction, inspection, repairing are conveniently, price is low, efficiency is identical and reliable replaces background technology, a kind of aerial cableway self-retention cycloidal reducer.
Think according to cableway association paper of China " analyzing failure cause seeks governance way ": the main problem of vertical cableway decelerator is leakage of oil; Inner Mongol Xinghua enginerring works, Mutianyu, Beijing ... " exploration of import passenger aerial ropeway reductor Home-produced Reconstruction " point out: the subject matter of cable reducer be heating, leakage of oil; China's cableway 2002.9 " lubrication of cable way driving machine tool reductor of having a talk " proposes: can cable reducer safe operation be depended on finding the change of oil product and oil mass in reductor in time.
(A) replacing three grades of theoretical foundations slowed down with single-stage cycloidal deceleration is that the two mechanical efficiency is identical: " 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. Due to inside and outside tooth be pure rolling mesh and lubricating status good, the cycloidal-pin wheel of ratio, bearing capacity about improves 50% (Shen Peiji " cycloidal equidistance curve gear driving pair and device thereof " 15 pages), but considers the machining accuracy of ring gear, and it is more reasonable to calculate by raising 1/3rd.
Technical scheme: couple a dome for covering bearing on the anchor ring of (1) vertical support central flange, it is prevented that lubricating oil enters bearing and spills from oil sealing; (2) capacity eccentric bearing outer collar rib makes Cycloidal Wheel can position in the vertical direction, it is to avoid rub between Cycloidal Wheel and spacer ring, causes that oil temperature raises; (3) equipped with dipstick on vertical support, it is simple to quickly check oil product, oil mass; (4) abat-vent of hypocycloid gear ring top dress exceeds 50～60mm, abat-vent main exhaustLeakage of oil is avoided to ensure reductor inner chamber oil pressure equal with environment;
(B) single-stage cycloidal retarding braking technical scheme: two groups of steel ball V-groove devices in brake component are that steel ball V-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-groove dish, the driven V-groove dish in telophragma side and two V-groove faces, and telophragma couples with cone dish; Second group is made up of the steel ball in the middle of telophragma opposite side actively V-groove dish, the second driven V-groove dish and two V-groove faces. Operation principle: during energising, first group actively V-groove is in the face of steel ball generation normal pressure, and its axial thrust load promotes the driven V-groove dish of telophragma to make friction pair separate, and braking moment disappears, and its circumference component drives the output shaft work done coupled with second group of driven V-groove dish;During power-off, power shaft stop, the moment of resistance makes the second driven V-groove produce normal pressure in the face of steel ball, and its axial thrust load makes friction pair compress, and braking moment much to have much.
[beneficial effect], according to background technology, its creativeness is embodied in:
(1) braking moment increases with the moment of resistance and automatically increases;
(2) cyclo drive is steadily, never broken teeth high-reliability, inside and outside cycloid tooth are rolling engagement, long service life;
(3) rotating mass on power shaft is in static balance, dynamic equilibrium state, makes transmission more steady;
(4) single-stage cycloidal cableway decelerator of the present invention and background technology: STJ type, HZL type compare sees following table:
