Abstract
The invention relates to the technical field of a reducer of an aerial cableway and discloses an involute small-tooth-difference reducer for an aerial cableway. The involute small-tooth-difference reducer comprises a vertical base (1), a motor (15), a connecting cylinder (17), an input shaft, an eccentric bearing, a planet gear, an inner gear ring and an output mechanism, wherein the output mechanism comprises an output shaft, a pin and a pin sleeve. The involute small-tooth-difference reducer is characterized in that the motor, the connecting cylinder, the inner gear ring and the vertical base are sequentially and integrally connected, a flange at the center of the base is connected with a round cover, 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 inner gear ring is 50-60mm higher than the top of the inner gear ring, and a main exhaust channel of the ventilation cap is phi25-phi35mm. The involute reducer with the small tooth difference has the advantages that the involute small-tooth-difference structure is simple, a plurality of teeth are meshed, the bearing capacity is larger, and the service life is long; the involute reducer with the small tooth difference is 40-50% lighter than STJ type and HZL type cableway cycloidal reducers in the background technology ((see a comparison sheet in a specification).
Description
[technical field] the present invention relates to aerial cableway speed reducer technical field, a kind of aerial cableway Reducer With Involute Gear of Less-tooth Difference.
[background technique] aerial cableway is widely used in mine transportation and perilous peak tourist attraction, and speed reducer is very important parts 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 inconvenience, bevel gear pair and planetary reduction gear parts valency high (be the 2-2.5 of cycloid doubly) and reliability are unstable, because the involute tooth root is stress raiser, 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 involute less tooth difference convenient, that price is low, efficient is identical and reliable replaces background technique, a kind of aerial cableway Reducer With Involute Gear of Less-tooth Difference.
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) replace three grades of decelerations with the deceleration of single-stage involute less tooth difference: " the calculated example of 7-126 page or leaf on the gear handbook: efficiency eta=0.944 (two teeth difference Z
d=2), the inventor is according to 100 examples, tooth difference Z
d=2,3,4, result of calculation draws: efficiency eta=0.934,0.96,0.97., thereby can replace background technique.
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) capacity eccentric bearing outer collar rib can be located planet wheel in the vertical direction, avoids rubbing between planet wheel and the spacer ring, causes oil temperature to raise; (3) on the vertical support dipstick is housed, is convenient to check fast oil product, oil mass; (4) abat-vent of ring gear 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) involute less tooth difference is simple in structure, cost is low, multiple tooth engagement driving is steady, the large long service life of bearing capacity;
(2) single-stage involute less tooth difference cableway retarder of the present invention and background technique: STJ type, HZL type relatively see the following form:
