Abstract
The utility model relates to a speed reducer, in particular to a worm-gear worm speed reducer with an input flange. The worm-gear worm speed reducer with the input flange mainly solves the problems of the prior art that: the speed reducer is directly connected with other devices through a worm-gear or a worm at a power output end or a power input end, in the way, the connecting shafts of the worm and the worm-gear are exposed outside, so as to enable dust and other things to easily invade and damage the device, thereby shortening the service life of the whole speed reducer. The worm-gear worm speed reducer comprises a box body (1), and is characterized in that: the worm-gear (2) is arranged inside the box body (1); an output shaft (11) passes through the worm-gear, and the worm-gear is meshed with the worm (3); the box body at the end of the worm-gear (2) is fixed with a worm-gear end cover (4); the worm-gear passes through the worm-gear end cover which is fixed with a torsional arm (5); the box body at the end of the worm (3) is fixed with the input flange (6); and the end part of the worm is extended 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 of tape input flange.
Background technique
At present, miniature gear speed reducer, the worm-gear speed reducer of being used widely, be subjected 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 vertical transmission direction to require again that slows down and install and use.Chinese patent discloses a kind of double worm and gear speed reducer structure (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 coupling of axial rotation adjustable 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 a small gear respectively; Small gear simultaneously and the gearwheel engagement driving, and with the transmission shaft at 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 housing of retarder itself separately, two worm type of reduction gearings and connected small gear respectively, has identical specification respectively, the coupling of employed axial rotation adjustable angle 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, worm gear in power output or input end, outside the coupling shaft of worm screw, worm gear promptly can be exposed to, make dust and other impurities invade easily, cause device damage, thereby 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 of tape input flange, it mainly is that solution existing in prior technology speed reducer all is directly to be connected with miscellaneous equipment by worm screw, worm gear in power output or input end, outside the coupling shaft of worm screw, worm gear promptly can be exposed to, make dust and other impurities invade easily, cause device damage, thereby 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:
The worm-gear speed reducer of tape input flange of the present utility model, comprise casing, described box house is provided with worm gear, cross-under has output shaft in the worm gear, 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 flange can be connected with miscellaneous equipment by bolt, outside the coupling that prevents worm screw is exposed to.Behind the worm screw input power, promptly 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.
As preferably, be provided with " O " RunddichtringO between described 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 two ends of described worm screw and the casing.Worm bearing can be so that worm gear rotation more smooth and easy.
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.
As preferably, the outer surface of described worm gear is provided with step, and step is provided with Worm Bearing respectively and between the casing, worm gear end cap, and Worm Bearing both can play the effect of supporting worm gear, can also make the worm gear rotation more smooth and easy.
Therefore, the utility model is provided with input flange at the power intake of worm screw, prevent that worm screw is exposed to outside, avoided the dust and other impurities intrusion, make the life-span of whole speed reducer subtract length, simple and reasonable for structure.
