The model utility content
The utility model provides a kind of lift, and it mainly is that to solve the structure of existing in prior technology lift comparatively complicated, and manufacture cost is higher, and the up-down direction sets up with direction of operating is vertical each other, operates the technical problem than inconvenience etc.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of lift of the utility model comprises casing, and described casing is connected with input flange; Be provided with worm screw in the casing at input flange place; Worm meshing has first worm gear, and first worm gear is connected with and connects worm screw, connects the worm screw cross-under in whole box body; The middle part that connects worm screw is engaged with second worm gear, and second worm gear is connected with screw mandrel through flat key.Can give worm screw with power transmission at the input flange place, power is transferred to first worm gear successively, connect worm screw, second worm gear, drive the screw mandrel rotation at last, thereby accomplish up-down work by worm screw.Connect on the worm screw because first worm gear, second worm gear are connected same, so worm screw is parallel setting up with screw mandrel that transmission direction is consistent, operates comparatively simple like this.
As preferably; Described casing includes left box body and right case, is fixed together through connecting cover between the left and right casing, and first worm gear places in the left box body; Second worm gear places in the right case; The outer end of left box body is fixed with big stifle, and the outer end of right case is fixed with oil seal cover, is provided with oil sealing in the oil seal cover.Left box body, right case can be fixed together through screw and connecting cover, and assembling is comparatively simple like this, like the need maintenance, only need the corresponding part of dismounting to get final product.
As preferably, be provided with clutch shaft bearing between described worm screw and the left box body, make things convenient for the rotation of worm screw.
As preferably, be provided with second bearing between described connection worm screw and the right case, the convenient rotation that connects worm screw.
As preferably, described right case is connected with loam cake, and screw mandrel stretches out outside the loam cake, and is connected with the 3rd bearing between screw mandrel and the right case, is provided with the 4th bearing between screw mandrel and the loam cake, and the screw mandrel rotation is comparatively smooth and easy like this.
Therefore, structure of the utility model and assembling are all comparatively simple, and manufacture cost is lower; And be connected same through first worm gear and second worm gear and be connected on the worm screw, make that worm screw and screw mandrel are parallel setting up, transmission direction is consistent; It is comparatively convenient to operate, and Applicable scope is wider.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the utility model;
Accompanying drawing 3 is H-H cross-sectional view of Fig. 1.
Component, position and numbering among the figure: input flange 1, worm screw 2, first worm gear 3, connect worm screw 4, second worm gear 5, flat key 6, screw mandrel 7, left box body 8, right case 9, connecting cover 10, big stifle 11, oil seal cover 12, oil sealing 13, clutch shaft bearing 14, second bearing 15, loam cake 16, the 3rd bearing 17, the 4th bearing 18.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technological scheme of the utility model.
Embodiment: a kind of lift of this example like Fig. 1, has a casing; Casing includes left box body 8 and right case 9; Be fixed together through connecting cover 10 between the left and right casing, be provided with connection worm screw 4 in the casing, be provided with second bearing 15 between connection worm screw and the right case.Be provided with first worm gear 3 in the left box body, be provided with second worm gear, 5, the first worm gears in the right case, second worm gear is engaged on end and the middle part that connects worm screw respectively.The outer end of left box body is fixed with big stifle 11, and the outer end of right case is fixed with oil seal cover 12, is provided with oil sealing 13 in the oil seal cover.Like Fig. 2, left box body is connected with input flange 1, is provided with worm screw 2 in the casing at input flange place, and worm meshing has first worm gear 3, is provided with clutch shaft bearing 14 between worm screw and the left box body.Like Fig. 3, right case 9 is connected with loam cake 16, and second worm gear in the right case is connected with screw mandrel 7 through flat key 6.Screw mandrel stretches out outside the loam cake, and is connected with the 3rd bearing 17 between screw mandrel and the right case, is provided with the 4th bearing 18 between screw mandrel and the loam cake.
