Abstract
The utility model relates to a speed reducer, in particular to a compact worm speed reducer. The compact worm speed reducer mainly solves the technical problems in the prior art that a speed reducer has a large volume, needs to occupy larger space when in use, has a shorter service life, is higher in production cost and the like. The compact worm speed reducer comprises a box body (1) and is characterized in that a worm (2) is arranged inside the box body (1); one end of the worm extends out of the box body; the worm is meshed with a worm gear; the worm gear is connected with an output shaft (3); the output shaft extends out of the box body; the box body in which the worm gear is positioned is of a circular arc shape; and one side of the box body is provided with an end cover (4).
Description
Technical field
The utility model relates to a kind of speed reducer, especially relates to a kind of compact type worm decelerating machine.
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 the volume of this speed reducer is larger, need to take larger space during use, and working life is shorter, becomes to produce cost higher.
The model utility content
The utility model provides a kind of compact type worm decelerating machine, and it mainly is that to solve the volume of the existing speed reducer of prior art larger, need to take larger space during use, and working life is shorter, becomes to produce the more high technical problem of cost.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of compact type worm decelerating machine of the present utility model comprises casing, is provided with worm screw in the described casing, the end of worm screw stretches out casing, and worm meshing has worm gear, and worm gear is connected with output shaft, output shaft stretches out outside the casing, and the casing at worm gear place is circular arc, and casing one side is provided with end cap.The chest portion minute profile at installing worm gear place is designed to circular arc, can reduces the shared space of whole speed reducer, comparatively compact.After worm screw is rotated, can drive the worm gear rotation, thus by output shaft with transmission of power to miscellaneous equipment.
As preferably, described worm gear includes the worm gear seat of cross-under on output shaft, and the cylindrical of worm gear seat is provided with the worm gear circle, and the worm gear circle is that wear-resisting non-ferrous metal is made.Worm gear adopts composite structure, and the worm gear circle adopts wear-resisting non-ferrous metal usually, both improves working life, reduces again manufacture cost.
As preferably, be provided with worm bearing between described worm screw and the casing, be provided with output shaft bearing between output shaft and the casing, can be so that worm screw, output shaft rotation more smooth and easy.
As preferably, the casing place that described worm screw stretches out is provided with the first shaft seal, and the casing that output shaft stretches out, end caps are respectively equipped with the second shaft seal, the 3rd shaft seal, can prevent that the fluid in the speed reducer from leaking.
Therefore, the utility model is circular arc by the cabinet design with the worm gear place, so that the small volume of speed reducer need not take very large space during use, and working life is longer, becomes to produce cost lower, simple and reasonable for structure.

Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of compact type worm decelerating machine of this example comprises casing 1, such as Fig. 1, Fig. 2, be provided with worm screw 2 in the casing, the end of worm screw stretches out casing, and worm meshing has worm gear, worm gear includes the worm gear seat 5 of cross-under on output shaft 3, and the cylindrical of worm gear seat is provided with worm gear circle 6.Worm gear is connected with output shaft, and output shaft stretches out outside the casing, and the casing at worm gear place is circular arc, and casing one side is provided with end cap 4.Be provided with worm bearing 7 between worm screw and the casing, be provided with output shaft bearing 8 between output shaft and the casing.The casing place that worm screw stretches out is provided with the first shaft seal 9, and the casing 1 that output shaft 3 stretches out, end cap 4 places are provided with respectively the second shaft seal 10, the 3rd shaft seal 11.
During use, worm screw 2 place's input powers, worm screw drives the worm gear rotation, and the coupling of output shaft 3 ends is connected with miscellaneous equipment by flat key, can be with transmission of power to miscellaneous equipment after the worm gear rotation.
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.
