Abstract
The utility model relates to a speed reducer, in particular to a worm gear speed reducer with an output flange, which mainly solves the technical problems that a speed reducer existing in the prior art is directly connected with other equipment by the aid of worms and worm gears at a power output end or a power input end, connecting shafts of the worms and the worm gears can be exposed outside so that impurities such as dust and the like are easy to intrude, the equipment are then damaged, the service life of the whole speed reducer is shortened accordingly, and the like. The worm gear speed reducer comprises a box (1), and is characterized in that a worm gear (2) is arranged in the box (1), an output shaft (4) is connected into the worm gear in a penetrating manner, the worm gear meshes with a worm (3), a torque arm (5) is fixed onto the box, the output flange (6) is fixed onto the box at the other end of the worm gear, and the end of the worm gear (2) extends into the output 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 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 with output 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 band output 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, worm gear is engaged with worm screw, be fixed with toggle on the casing, be fixed with output flange on the casing of the worm gear the other end, the worm gear end is stretched in the output flange.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 then.Output flange can be connected with miscellaneous equipment by bolt, outside the output shaft that prevents worm gear is exposed to.
As preferably, the outer surface of described worm gear is provided with step, is provided with Worm Bearing between step and the casing.Worm Bearing both can play the effect of supporting worm gear, can also make the worm gear rotation more smooth and easy.
As preferably, the two ends of described worm gear respectively and be provided with oil sealing between the casing prevent that the fluid in the casing from leaking outside.
As preferably, be fixed with input flange on the casing of described worm screw one end, be provided with worm bearing between worm screw and the casing.Input flange can be connected with miscellaneous equipment by bolt, outside the coupling that prevents worm screw is exposed to.
Therefore, the utility model all is provided with flange at the power intake of worm screw and the clutch end of worm gear, prevent that worm screw, worm gear are 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.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is left TV structure schematic representation of Fig. 1.
Component, position and numbering among the figure: casing 1, worm gear 2, worm screw 3, output shaft 4, toggle 5, output flange 6, Worm Bearing 7, oil sealing 8, input flange 9, worm bearing 10.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the worm-gear speed reducer of the band output flange of this example, as Fig. 1, Fig. 2, a casing 1 is arranged, box house is provided with worm gear 2, and cross-under has output shaft 4 in the worm gear, is fixed with toggle 5 on the casing.The outer surface of worm gear is provided with step, is provided with bearing 7 between step and the casing.Be provided with oil sealing 8 between the two ends of worm gear and the casing.Be fixed with output flange 6 on the casing 1 of the worm gear the other end, the worm gear end is stretched in the output flange.The worm gear middle part is engaged with worm screw 3, is fixed with input flange 9 on the casing of worm screw one end, is provided with worm bearing 10 between worm screw and the casing.
During use, worm screw 3 places input power, worm screw drives worm gear 2 rotations, and the coupling of output shaft 4 ends is connected with miscellaneous equipment by flat key, can give miscellaneous equipment with transmission of power after the worm gear rotation.
The above only is a specific embodiment of the utility model, but structure characteristic of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and variation of being done or modification all are encompassed among the claim of the present utility model.
