Abstract
The utility model relates to reduction box parts, in particular to a compact type reduction box casing with strengthening radiating ribs, which mainly solves the technical problem that the inside of a reduction box in the prior art has no strengthening rib, so that strength of the whole casing is poor during operation, the casing is easy to break in use, and the service life is shorter and the like. The compact type reduction box casing comprises a box body (1) and is characterized in that a worm cavity (2) is arranged on the upper portion of the box body (1), a worm gear cavity (3) is arranged on the lower portion of the box body (1), the worm cavity and the worm gear cavity are vertical, an input flange (4) is arranged at one end of the worm cavity, worm gear holes (5) are arranged at two ends of the worm gear cavity (3), a plurality of strengthening radiating ribs (6) are arranged on the inner surface of each worm gear hole, and the strengthening radiating ribs are distributed along the radial direction.
Description
Technical field
The utility model relates to a kind of speed reducer component, especially relates to a kind of with the compact type reducer shell of strengthening radiating fin.
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.But stiffening rib is not set up in this speed reducer inside, and the intensity of whole housing is relatively poor when therefore turning round, and breaks in use easily, and working life is shorter.
The model utility content
The utility model provides a kind of with the compact type reducer shell of strengthening radiating fin; It mainly is to solve existing in prior technology speed reducer inside not set up stiffening rib; Therefore the intensity of whole housing is relatively poor when turning round, and breaks in use easily, the technical problem that working life is short etc.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
The a kind of of the utility model comprises casing with the compact type reducer shell of strengthening radiating fin, and described casing top is provided with the worm screw cavity; Lower box is provided with the worm gear cavity; Worm screw cavity and the worm gear cavity is orthogonal sets up, an end of worm screw cavity is provided with input flange, and the two ends of worm gear cavity are worm wheel aperture; The internal surface of worm wheel aperture is provided with some reinforcement radiating fin, strengthens radiating fin and is radially direct.Many stiffening ribs are set in reducer shell, can not only increase the intensity of whole housing, still absorb the heat that send whole speed reducer inside, play the effect of heat radiation, make speed reducer normally to move.Worm screw cavity and the worm gear cavity is orthogonal sets up makes that transmission direction can be vertical, and the input flange place can import power, then from worm gear cavity outputting power.
As preferably, the two ends of described worm screw cavity are worm hole, and wherein the worm hole outer rim of end integral body is circular, and the upper surface of worm hole is the plane.At the worm hole upper surface plane is set, can economical with materials, reduce manufacture cost.
As preferably, the two ends outer rim of described worm wheel aperture is a straight flange, and the bottom outer rim of worm wheel aperture is a trapezoidal side.The rectangular edges that is about to worm wheel aperture is cut away two corners, makes material therefor less, and manufacture cost is lower.
As preferably, the length L 1 of described worm screw cavity is 67.2-77.2mm.The volume of speed reducer is comparatively compact like this.
As preferably, the length L 2 of described worm gear cavity is 36.5-46.5mm.The volume of speed reducer is comparatively compact like this.
Therefore, the utility model is provided with many stiffening ribs in the housing of speed reducer, can play the effect of strengthening whole speed reducer intensity, and stiffening rib can also absorb the inner heat of speed reducer, has played the effect of heat radiation, and is simple and reasonable for structure.
