Abstract
The utility model relates to a reducer, in particular to a direct connection type twin-stage worm and gear reducer of a motor. The direct connection type twin-stage worm and a gear reducer of the motor mainly solves the technical problems that a power output end or a power input end of the reducer in the prior art is directly connected with other equipment through a worm and an output shaft, the worm and the output shaft are exposed outdoors, sundries such as dust are easy to invade and cause equipment damage, and then service life of a whole reducer is reduced, and the like. The direct connection type twin-stage worm and a gear reducer of the motor comprises a primary box body (1) and is characterized in that a primary worm (2) is arranged in the primary box body (1), the primary worm (2) is connected with a primary gear, the primary gear is connected with a secondary worm (3), the secondary worm is arranged in a secondary box body (4), the primary box body (1) is connected with the secondary box body (4) through a connecting sleeve (5), and an input flange (6) is fixed on the secondary box body (4).
Description
Technical field
The utility model relates to a kind of speed reducer, especially relates to a kind of motor direct-connection type two-stage worm gear-worm reducer.
Background technique
At present, miniature gear speed reducer, the worm-gear speed reducer of being used widely, be subject 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 again the vertical-transmission direction to require that slows down and install and use.Chinese patent discloses a kind of double worm gear reducing mechanism (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 adjustable coupling of axial rotation 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 respectively a small gear; Small gear simultaneously and the gearwheel engagement driving, and with the transmission shaft at the 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 separately housing of retarder itself, two worm type of reduction gearings and connected small gear respectively, has respectively identical specification, the coupling that employed axial rotation angle is adjustable 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, output shaft in power output or input end, outside worm screw, output shaft namely can be exposed to, easily so that dust and other impurities invade, cause damage of equipment, thus cause the life-span of whole speed reducer to reduce.
The model utility content
The utility model provides a kind of motor direct-connection type two-stage worm gear-worm reducer, it mainly is that the existing speed reducer of solution prior art all is directly to be connected with miscellaneous equipment by worm screw, output shaft in power output or input end, outside worm screw, output shaft namely can be exposed to, easily so that the dust and other impurities intrusion, cause damage of equipment, thus 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:
Motor direct-connection type two-stage worm gear-worm reducer of the present utility model, comprise main box body, be provided with main worm gear in the described main box body, main worm gear is connected with main worm screw, main worm screw auxiliary connection worm gear, secondary worm gear is located in the auxiliary housing, and main box body links together by connecting sleeve and auxiliary housing, is fixed with input flange on the auxiliary housing.Input flange can be connected with miscellaneous equipment by bolt, prevent that input shaft is exposed to outside.Behind the input shaft input power, namely begin to rotate with the secondary worm gear of its engagement, at last by main worm screw, main worm gear outputting power.Be provided with " O " RunddichtringO between input flange and the auxiliary housing, prevent that dust from entering in the speed reducer from the slit between flange and the auxiliary housing.
As preferably, the end face of described main box body is provided with oil sealing, prevents that the fluid in the main box body from leaking outside.
As preferably, the end face of described auxiliary housing is provided with oil seal cover, prevents that the fluid in the auxiliary housing from leaking outside.
Therefore, the utility model is provided with input flange at input shaft end, prevent that input shaft is exposed to outside, avoided the dust and other impurities intrusion so that 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.
Component, position and numbering among the figure: main box body 1, main worm gear 2, secondary worm gear 3, auxiliary housing 4, connecting sleeve 5, input flange 6, oil sealing 7, oil seal cover 8.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the motor direct-connection type two-stage worm gear-worm reducer that this is routine, such as Fig. 1, comprise main box body 1, be provided with main worm gear 2 in the main box body, main worm gear is connected with main worm screw, main worm screw auxiliary connection worm gear 3, and secondary worm gear is located in the auxiliary housing 4, main box body links together by connecting sleeve 5 and auxiliary housing, is fixed with input flange 6 on the auxiliary housing.The end face of main box body is provided with oil sealing 7.The end face of auxiliary housing is provided with oil seal cover 8.
During use, the input shaft place input power of auxiliary housing 4, input shaft drive secondary worm gear rotation, and secondary worm gear rotates by main worm screw, main worm gear 2 can be with transmission of power to miscellaneous equipment.
The above only is specific embodiment of the utility model, but structure characteristic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification all are encompassed among the claim of the present utility model.
