Description
Technical field
The utility model relates to a kind of speed reducer, especially relates to a kind of speed reducer that is used for woodworking machinery.
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.Process but the casing of this speed reducer separates with base, so join strength is relatively poor, in use because vibrations can produce fracture, and the power input source of speed reducer is positioned at the speed reducer below, and operation is inconvenience comparatively.
The model utility content
The utility model provides a kind of speed reducer that is used for woodworking machinery; It mainly is that the casing that solves the existing in prior technology speed reducer separates with base and processes; Therefore join strength is relatively poor; In use because vibrations can produce fracture, and the power input source of speed reducer is positioned at the speed reducer below, operates the technical problem of comparatively inconvenience etc.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
The speed reducer that is used for woodworking machinery of the utility model comprises base, and base top is provided with casing; Described base and casing integral body are processed, and the top of casing is connected with input flange, and box house, input flange cross-under have worm screw; The worm screw middle part is engaged with worm gear; Be fixed with output shaft through flat key in the middle of the worm gear, a side of casing is fixed with end cap, and output shaft one end stretches out outside the end cap.Behind the worm screw input power, promptly begin to rotate with the worm gear of its engagement, output shaft is given in last transmission, and output shaft can be connected with miscellaneous equipment through flat key.Base and casing integral body are processed, and can disposablely machine like this, and whole speed reducer casing can not produce fracture in use, and are positioned at the top of speed reducer as the input flange of power input source, operate comparatively easy.
As preferably, be provided with first tapered roller bearing between described worm screw two ends and the casing.Can make that like this worm screw is more smooth and easy rotatably.
As preferably, all be provided with second tapered roller bearing between described output shaft and casing, the end cap.Can make that like this output shaft is more smooth and easy rotatably.
As preferably, described input flange the inner is provided with first oil sealing.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 outer end of described end cap is provided with second oil sealing.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.
Therefore, the utility model is processed casing and base integral body, and the intensity of the speed reducer whole box body that is is stronger, can not meet accident during use, and input flange is placed the top of speed reducer, makes that operation is comparatively convenient, simple and reasonable for structure.
