Abstract
The utility model relates to a reducer, in particular to a double worm-and-gear reducer with shaft input. The double worm-and-gear reducer mainly solves the technical problem that the reducer in the prior art is connected with the other devices at the power input or output end through the shaft thereof, so the connection is complicated, and the transmission efficiency is low. The double worm-and-gear reducer with shaft input comprises a main box body (1), and is characterized in that a main worm gear (2) is arranged in the main box body (1); the main worm gear is connected with a main worm; the main worm is connected with a secondary worm gear (3); the secondary worm gear is arranged inside a secondary box body (4); the secondary worm gear is connected with a shaft input worm gear (5); and the main box body is connected with the secondary box body through a connecting sleeve (6).
Description
Technical field
The utility model relates to a kind of speed reducer, especially relates to a kind of two-stage worm gear-worm reducer of tape spool input.
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 to be connected with miscellaneous equipment by axle in power output or input end, connects comparatively loaded down with trivial detailsly, and transmission efficiency is lower.
The model utility content
The utility model provides a kind of two-stage worm gear-worm reducer of tape spool input, it mainly is that the existing speed reducer of solution prior art all is to be connected with miscellaneous equipment by axle in power output or input end, connect comparatively loaded down with trivial details, the low technical problem that waits of transmission efficiency.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The two-stage worm gear-worm reducer of tape spool input 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 secondary worm gear is connected with axle input worm screw, and main box body links together by connecting sleeve and auxiliary housing.Behind the axle input worm screw 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.
As preferably, the end face of described main box body is provided with the main box body 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 the auxiliary housing oil sealing, prevents that the fluid in the main box body from leaking outside.
Therefore, the utility model is connected with miscellaneous equipment by axle input worm screw, connects comparatively simply, and transmission efficiency is higher, and is 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, axle input worm screw 5, connecting sleeve 6, main box body oil sealing 7, auxiliary housing oil sealing 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 two-stage worm gear-worm reducer of the tape spool input 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, secondary worm gear is connected with axle input worm screw 5, and main box body links together by connecting sleeve 6 and auxiliary housing.The end face of main box body is provided with main box body oil sealing 7.The end face of auxiliary housing is provided with auxiliary housing oil sealing 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.
