Abstract
The utility model relates to a reducer, in particular to a worm-and-gear reducer with an output flange. The worm-and-gear reducer mainly solves the technical problem that the reducer in the prior art is directly connected with the other devices at the power output or input end through a worm and an output shaft, and the worm and the output shaft are exposed outside, so the impurities such as dust are easy to invade to cause damage to the device and further shorten the service life of the whole reducer. The worm-and-gear reducer comprises a box body (1), wherein a worm gear (2) is arranged inside the box body; an output shaft (3) is connected with the worm gear in a penetrating manner; an output flange (4) is fixed on the box body at one end of the output shaft; the output shaft is inserted into the output flange; the worm gear is meshed with a worm (5); a worm gear end cap (6) is fixed on the box body at one end of the worm gear; the worm gear is connected to the worm gear end cap in a penetrating manner; a torque arm (7) is fixed on the worm gear end cap; an input flange (8) is fixed on the box body at the other end of the worm; and the end part of the worm is inserted into the input flange.
Description
Technical field
The utility model relates to a kind of speed reducer, especially relates to a kind of worm-gear speed reducer with output flange.
Background technique
At present, miniature gear speed reducer, the worm-gear speed reducer of being used widely, be subject to volume restrictions, its speed ratio is less than normal, and its transmission direction is generally parallel input output and can not satisfies some existing large speed ratios mini-plant that has again the vertical-transmission direction to require that slows down and install and use.Chinese patent discloses a kind of double worm gear reducing mechanism (notice of authorization number: CN 201250880Y), it comprises worm type of reduction gearing, be provided with two worm type of reduction gearings, worm screw on two worm type of reduction gearings links together by the adjustable coupling of axial rotation angle, realizes synchronization; Have at least one worm screw two ends all to stretch out in himself reducer shell in two worm type of reduction gearings, with a end that coupling is not installed on this worm screw input shaft as this reducing gear; Output shaft on each worm type of reduction gearing is connected with respectively a small gear; Small gear simultaneously and the gearwheel engagement driving, and with the transmission shaft at the gearwheel place output shaft as this reducing gear; The two ends of the worm screw of two worm type of reduction gearings all stretch out in the separately housing of retarder itself, two worm type of reduction gearings and connected small gear respectively, has respectively identical specification, the coupling that employed axial rotation angle is adjustable is made of two half-couplings, some screws evenly distribute on one of them half-coupling, corresponding described screw is provided with the slotted hole of some arcs on another half-coupling, is fastenedly connected by screw between two half-couplings.But this speed reducer all is directly to be connected with miscellaneous equipment by worm screw, output shaft in power output or input end, outside worm screw, output shaft namely can be exposed to, easily so that dust and other impurities invade, cause damage of equipment, thus cause the life-span of whole speed reducer to reduce.
The model utility content
The utility model provides a kind of worm-gear speed reducer with output flange, it mainly is that the existing speed reducer of solution prior art all is directly to be connected with miscellaneous equipment by worm screw, output shaft in power output or input end, outside worm screw, output shaft namely can be exposed to, easily so that the dust and other impurities intrusion, cause damage of equipment, thus cause life-span of whole speed reducer to reduce the technical problem that waits.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Worm-gear speed reducer with output flange of the present utility model, comprise casing, described box house is provided with worm gear, and cross-under has output shaft in the worm gear, be fixed with output flange on the casing of output shaft one end, output shaft extend in the output flange, and worm gear is engaged with worm screw, is fixed with the worm gear end cap on the casing of worm gear one end, the worm gear cross-under is on the worm gear end cap, the worm gear end cap is fixed with toggle, is fixed with input flange on the casing of worm screw one end, and the worm screw end is stretched in the input flange.Input, output flange can be connected with miscellaneous equipment by bolt, prevent that output shaft is exposed to outside.Behind the worm screw input power, namely begin to rotate with the worm gear of its engagement, by the coupling outputting power of output shaft end, coupling can be connected with miscellaneous equipment by flat key at last.Be provided with " O " RunddichtringO between input flange and the casing, prevent that dust from entering in the speed reducer from the slit between flange and the casing.
As preferably, be provided with worm bearing between the two ends of described worm screw and the casing.Worm bearing can be so that worm gear rotation more smooth and easy.
As preferably, the casing of described worm screw outer end is provided with oil seal cover, prevents that the fluid in the casing from leaking outside.
As preferably, be provided with oil sealing between described input flange and the worm screw, prevent that the fluid in the casing from leaking outside.
Therefore, the utility model is provided with input flange at output shaft end, prevent that output shaft is exposed to outside, avoided the dust and other impurities intrusion so that the life-span of whole speed reducer subtract length, simple and reasonable for structure.
