Background technique
At present; Miniature gear speed reducer, the worm-gear speed reducer of being used widely; Receive 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 through 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; Have identical specification respectively, the coupling of employed axial rotation adjustable angle is made up of two half-couplings, and 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 through screw between two half-couplings.But the input flange of this speed reducer all is horizontally disposed with, and the worm screw of importing as power also is horizontally disposed with, and therefore shared horizontal area is bigger, and not being suitable for high-voltage switch gear need be than the requirement of small size.
The model utility content
The utility model provides a kind of speed reducer that is used for high-voltage switch gear; It mainly is that the input flange that solves the existing in prior technology speed reducer all is horizontally disposed with; Worm screw as the power input also is horizontally disposed with; Therefore shared horizontal area is bigger, and not being suitable for high-voltage switch gear need be than the technical problem of the requirement of small size etc.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of speed reducer that is used for high-voltage switch gear of the utility model comprises casing, and described casing top is connected with the input casing through connecting sleeve; Input casing lower end is fixed with input flange; The input flange large end face is provided with down, and input flange inside is provided with first worm screw of vertically setting up, and first worm meshing has small gear; Small gear is fixed with coupling shaft through flat key; Coupling shaft the inner is connected with second worm screw through flat key, and second worm meshing has big worm gear, and second worm screw, big worm gear place in the casing.Behind first worm screw input power, promptly begin to rotate with the small gear of its engagement, the coupling shaft that is connected with small gear can drive second worm screw and rotate, and drives big worm gear rotation through second worm screw then, thereby high-voltage switch gear is imported power.Input flange is provided with down, and first worm screw is vertically to be provided with, and can reduce the horizontal area of speed reducer really like this, thereby it is little to reach floor space, can be suitable for the purpose of high-voltage switch gear.
As preferably, all be provided with clutch shaft bearing between two ends and the input casing about described first worm screw.Can make the worm screw of winning more smooth and easy rotatably like this.
As preferably, be provided with first oil sealing between the small end face of described input flange and first worm screw.First oil sealing can prevent that the fluid in the casing from leaking outside, and also can prevent that the outside dust and other impurities of speed reducer from invading speed reducer inside simultaneously.
As preferably, the two ends of described small gear are provided with second bearing respectively and between the connecting sleeve input casing.Can make that like this small gear is more smooth and easy rotatably.
As preferably, all be provided with second oil sealing on the exterior edge face of described connecting sleeve, input casing.Second oil sealing can prevent that the fluid in the casing from leaking outside, and also can prevent that the outside dust and other impurities of speed reducer from invading speed reducer inside simultaneously.
As preferably, be provided with the 3rd bearing between two ends of described second worm screw and the casing.Can make that like this second worm screw is more smooth and easy rotatably.
As preferably, be provided with the 4th bearing between the two ends of described big worm gear and the casing, the 4th bearing outside is provided with the 3rd oil sealing.Can make that so big worm gear is more smooth and easy rotatably.
Therefore, the utility model is provided with input flange down, and makes the worm screw of input power vertically set up, and so just can reduce the floor space of whole speed reducer, makes its installation requirement that can adapt to high-voltage switch gear, and is simple and reasonable for structure.
