Abstract
The utility model relates to a speed reducer, in particular to a worm-gear worm speed reducer with an arc-surface box. The utility model mainly aims at solving the problems of the prior art that the box of the speed reducer is designed as a rectangular shape, the distance between the upper surface of the box and the worm is long to cause large volume, so large space is occupied in actual use, and the manufacturing cost is high and the like. The worm-gear worm speed reducer with the arc-surface box comprises a box (1). The worm-gear worm speed reducer is characterized in that: the upper surface of the box (1) is in a concave arc shape; a worm gear (2) is arranged inside the box; an output shaft (9) passes through the worm gear; the worm gear is meshed with a worm (3); the box at one end of the worm gear (2) is fixed with a worm-gear end cover (4); the worm gear passes through a worm-gear end cover; and the worm-gear end cover is fixed with a torsion arm (5).
Description
Technical field
The utility model relates to a kind of speed reducer, especially relates to a kind of worm-gear speed reducer with the cabochon casing.
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 the cabinet design of this speed reducer is a rectangle, and the upper surface of casing and the spacing of worm screw are bigger, thereby make volume bigger, need in actual use to take than large space, and manufacture cost are bigger.
The model utility content
The utility model provides a kind of worm-gear speed reducer with the cabochon casing, it mainly is that the cabinet design of solution existing in prior technology speed reducer is a rectangle, the upper surface of casing and the spacing of worm screw are bigger, thereby make volume bigger, need in actual use to take than large space, and bigger etc. the technical problem of manufacture cost.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The worm-gear speed reducer of band cabochon casing of the present utility model, comprise casing, described casing upper surface is recessed circular arc, 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, and the worm gear end cap is fixed with toggle.After the casing upper surface of worm screw top is recessed, only form a running clearance, neither hinder the worm screw rotation, can dwindle the volume of whole box body again with worm screw.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.
As preferably, be fixed with output flange on the casing of the described worm gear the other end, the worm gear end is stretched in the output flange.Output flange can be connected with miscellaneous equipment by bolt, outside the coupling that prevents worm gear is exposed to.
As preferably, the outer surface of described worm gear is provided with step, and step is provided with bearing respectively and between the casing, worm gear end cap.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 are provided with oil sealing respectively and between the casing, worm gear end cap, prevent that the fluid in the casing from leaking outside.
Therefore, the utility model is designed arc shaped surface at the upper surface of casing, makes that the spacing of the upper surface of casing and worm screw is less, thereby makes that shared volume is less, and need not to take very big space in actual use, manufacture cost is less, and is 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, worm gear end cap 4, toggle 5, output flange 6, bearing 7, oil sealing 8, output shaft 9.
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 cabochon casing of this example, as Fig. 1, Fig. 2, comprise casing 1, the upper surface of casing is recessed circular arc, box house is provided with worm gear 2, and cross-under has output shaft 9 in the worm gear, is fixed with worm gear end cap 4 on the casing of worm gear one end, the worm gear cross-under is on the worm gear end cap, and the worm gear end cap is fixed with toggle 5.The outer surface of worm gear is provided with step, and step is provided with bearing 7 respectively and between the casing, worm gear end cap.The two ends of worm gear are provided with oil sealing 8 respectively and between the casing, worm gear end cap.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.
During use, worm screw 3 places input power, worm screw drives worm gear 2 rotations, and output shaft 9 ends are connected with miscellaneous equipment by the coupling 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.
