Abstract
A lead screw elevator comprises an outer shell body, a worm, a worm wheel driven by the worm, and a screw driven by the worm wheel, wherein the screw is fixedly connected with the worm wheel, and the screw is sleeved with a loading nut cooperated with screw thread of the screw. The beneficial effects of the utility model are that firstly, the lathy screw only does the rotating motion and doesn't lift, and the relatively smaller loading nut does the lifting motion, which saves the stroke space, thereby the utility model can use the smaller space to realize the larger stroke; and secondly, the loading nut is regarded as the loading component, the loading component is uneasy to deform, thereby the utility model is safer and more reliable.
Description
(1) technical field
The utility model relates to a kind of screw lift.
(2) background technology
Screw lift is the weight in the elevator, as a rule, the load-carrying part of screw lift is a screw mandrel, promptly drives the lifting of weight by the up-and-down movement of screw mandrel, the shortcoming that the screw lift of this structure also exists is: the stroke of screw mandrel is longer, and occupation space is very big during operation; And with the screw mandrel of strip as the load-carrying part, the weight of load easily causes bending, the distortion of load-carrying part, has certain hidden danger in safety.
(3) summary of the invention
To take up room greatly when screw lift moves in the prior art in order overcoming, to exist certain safety, the screw lift little with the space, safety and reliability of standing when the utility model provides a kind of the operation with deficiency also.
The technical scheme in the invention for solving the technical problem is: a kind of screw lift, comprise body skin, worm screw, by the worm gear of described worm drive, by the screw rod of described worm-gear driven, described screw rod and described worm gear are affixed, are arranged with the load-carrying nut of screw thread fit with it on the described screw rod.
Further, described screw rod is connected by flat key with described worm gear.
The utility model by the worm screw imput power, drives worm gear and rotates when work, worm gear drives affixed with it screw rod again and rotates, the rotation of screw rod can drive the load-carrying nut and do dipping and heaving along screw rod, and weight is stated from this load-carrying nut, thereby realizes the lifting of weight.
The beneficial effects of the utility model are: 1. elongated screw rod only rotates and not lifting, and allows relative shorter and smaller load-carrying nut do dipping and heaving, saved the stroke space, thereby bigger stroke is realized in available less space.2. be the load-carrying part with the load-carrying nut, the load-carrying part is difficult for producing distortion, safety and reliability.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, a kind of screw lift, the worm gear 3 that comprises body skin 1, worm screw 2, driven by described snail 2 bars, the screw rod 4 that is driven by described worm gear 3, described screw rod 4 and described worm gear 3 are connected by flat key, are arranged with the load-carrying nut 5 of screw thread fit with it on the described screw rod 4.
The utility model by worm screw 2 imput powers, drives worm gear 3 and rotates when work, worm gear 3 drives screw rod 4 by flat key again and rotates, the rotation of screw rod 4 can drive load-carrying nut 5 and do dipping and heaving along screw rod 4, and weight is stated from this load-carrying nut 5, thereby realizes the lifting of weight.
Claims (2)
1. screw lift, comprise body skin, worm screw, by the worm gear of described worm drive, by the screw rod of described worm-gear driven, it is characterized in that: described screw rod and described worm gear are affixed, are arranged with the load-carrying nut of screw thread fit with it on the described screw rod.
2. screw lift as claimed in claim 1 is characterized in that: described screw rod is connected by flat key with described worm gear.
