Description
Technical field
The utility model relates to a kind of speed reducer, especially relates to a kind of full seal type worm-gear speed reducer.
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 lacks seal arrangement at the binding site of each component, and speed reducer dust and other impurities in use can enter speed reducer inside, thereby causes whole device interior to damage, and influences the life-span of speed reducer.
The model utility content
The utility model provides a kind of full seal type worm-gear speed reducer, it mainly is to solve the existing in prior technology speed reducer to lack seal arrangement at the binding site of each component, speed reducer dust and other impurities in use can enter speed reducer inside, thereby cause whole device interior to damage, influence the technical problem in life-span etc. of speed reducer.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Full seal type worm-gear speed reducer 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 sealed with oil seal cover on the casing of worm screw one end, be 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, and the two ends of worm gear are provided with the worm gear oil sealing respectively and between the casing, worm gear end cap.The worm gear oil sealing can prevent that the fluid on the worm gear from leaking outside, and can prevent that also the dust and other impurities of speed reducer outside from invading speed reducer inside simultaneously.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, the casing of the described worm screw the other end is provided with input flange, is provided with the worm screw oil sealing between worm screw and the input flange.Input flange can be connected with miscellaneous equipment by bolt, outside the coupling that prevents worm screw is exposed to.Worm screw oil sealing on the input flange can prevent that the fluid in the casing from leaking outside.
As preferably, between described input flange and the casing, all be provided with " O " RunddichtringO between casing and the worm gear end cap, 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, 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 adds seal arrangement at speed reducer at the binding site bucket of each component, prevent speed reducer in use dust and other impurities can enter speed reducer inside, therefore can not cause whole device interior to damage, thereby prolong the life-span of speed reducer, simple and reasonable for structure.
