Abstract
The invention relates to the technical field of a reducer of an aerial cableway and discloses a cycloidal reducer of the aerial cableway. The cycloidal reducer comprises a vertical base, a motor, a connecting cylinder, an input shaft, an eccentric bearing, a cycloidal gear, a needle tooth case, a needle pin and an output mechanism, wherein the output mechanism comprises an output shaft, a pin and a pin sleeve. The cycloidal reducer is characterized in that the motor, the connecting cylinder, the needle tooth case and the vertical base are sequentially and integrally connected, a flange at the center of the base is connected with a round cover, half of the needle pin is embedded in the needle tooth case, an outer ferrule with a rib is arranged on the external circle of the eccentric bearing, a dipstick is arranged on the base, a ventilation cap installed at the top of the needle tooth case is 50-60mm higher than the top of the needle tooth case, and a main exhaust channel of the ventilation cap is phi25-phi35mm. The cycloidal reducer has the advantages that cycloid transmission is stable, tooth breakage never occurs, the reliability is high, the pin and the cycloidal gear are meshed in a rolling mode, and the service life is long; the cycloidal reducer is 40-50% lighter than STJ type and HZL type cableway cycloidal reducers in the background technology.
Description
[technical field] the present invention relates to aerial cableway speed reducer technical field, a kind of aerial cableway cycloidal reducer.
[background technique] aerial cableway is widely used in mine transportation and perilous peak tourist attraction, and speed reducer is vitals very in the aerial cableway, and the high reliability speed reducer can be protected the safety of thousands of people's life and property.Background technique has three kinds:
(1) STJ type aerial cableway speed reducer (seeing into the volume 4.16-235 of large elder generation " mechanical design handbook " page or leaf): the STJ type speed reducer is combined by arc bevel gear drive and cylindrical planetary gear speed reducer, be three grades of vertical type transmissions, the STJ type mainly is applicable to aerial cableway, the vertical type transmission that also can be used for other machinery, particularly relatively high power.Shortcoming is: complex structure, maintenance are inconvenient, and bevel gear pair and planetary reduction gear parts valency high (be the 2-2.5 of cycloid doubly) owing to the involute tooth root is stress raiser, thereby when carburizing and quenching and grinding, microcrack very easily occurs and cause break of gear tooth;
(2) twoly enter formula aerial cableway planetary reduction gear (ZL200520111177.5): dual-motor input, arc bevel gear-three grades of vertical type transmissions of cylinder planet, shortcoming is: the inventor thinks that retarder can not quit work when wherein a motor breaks down, this can only be in load less than specified 50% the time, retarder ability normal rotation, otherwise the separate unit motor can't drive retarder at all.Therefore can conclude that the 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 that is existing involute less tooth difference: ring gear output; The pin of pin axle type output mechanism changes double-eccentric shaft into, four selfaligning roller bearings are housed on the axle, the inventor is called the rolling star-wheel with this, be supported on respectively in four bearings in two-side supporting dish and the two planet wheel pin-and-holes, because planet wheel is very wide, therefore having added one in each pin-and-hole is called auxiliary bearing.Shortcoming is: complex structure, the maintenance extremely inconvenient, star reduction part device cost ratio planetary reducer will exceed 20-30%.Can find the aerial cableway HZL planetary-gear speed reducer of certain company on the net: rated power 80kW, input speed 1500rpm, allowable torque: 80000N.m, work as present value: 200000 yuan/platform.
That [summary of the invention] the object of the invention provides is simple in structure, check, repair the vertical single-stage cycloid convenient, that price is low, efficient is identical and reliable replaces background technique, a kind of aerial cableway cycloidal reducer.
Think according to Chinese cableway association's paper " analyzing failure cause is sought governance way ": the main problem of vertical cableway retarder is leakage of oil; Inner Mongol Xing Hua enginerring works, Mutianyu, Beijing ... " exploration of import passenger aerial ropeway speed reducer Home-produced Reconstruction " point out: the subject matter of cable reducer be the heating, leakage of oil; China's cableway 2002.9 " lubricating of the cable way driving machine tool speed reducer of having a talk " proposes: can the cable reducer safe operation depend on the variation that in time find the interior oil product of speed reducer and oil mass.
(A) theoretical foundation with three grades of decelerations of single-stage cycloidal deceleration replacement is that the two mechanical efficiency is identical: " the gear handbook (on) the 8-3 page or leaf: cycloid η=0.93-0.95; Zhu Xiaolu " 6 pages of Gear Transmission Design handbook, " 1-12 page or leaf on the gear handbook: cycloid efficiency eta=0.9～0.98 ≈ 0.94; Its practicability (value) is: simple in structure, cost is at half approximately.
Technological scheme: toroidal surface upper joint one dome of (1) vertical support central flange is used for covering bearing, prevents that lubricant oil from entering bearing and spilling from oil sealing; (2) partly burying toothing makes needle pin have very high bending force; (3) rely on the rib of capacity eccentric bearing outer collar that cycloid wheel can be located in the vertical direction, avoid rubbing between cycloid wheel and the spacer ring, cause oil temperature to raise; (4) on the vertical support dipstick is housed, is convenient to check fast oil product, oil mass; (5) abat-vent of pin wheel housing top dress exceeds 50～60mm, and main exhaust φ 25～φ 35mm avoids leakage of oil to guarantee speed reducer inner chamber oil pressure to equate with environment.
According to background technique, its creativeness is embodied in [beneficial effect]:
(1) the cycloid stable drive, never broken teeth high-reliability, pin-cycloid wheel be for the engagement of rolling, the life-span is long, price is low;
(2) single-stage cycloidal cableway retarder of the present invention and background technique STJ type, HZL type relatively see the following form:
