Abstract
The utility model relates to a screw lift. The lift comprises a box, a worm, a worm wheel driven by the worm, and a screw driven by the worm wheel, wherein the worm and the worm wheel are installed in the box; an end cover is fixedly arranged at the upper end of the box; the screw is fixedly connected to the middle part of the worm wheel and penetrates through the box and the end cover; and an oil seal is arranged between the worm and the box. The screw lift disclosed by the utility model is simple and compact in structure and capable of saving installation space and has the advantages of good transmission stability, high accuracy and the like simultaneously.
Description
Technical field
The utility model belongs to field of mechanical technique, specifically relates to a kind of screw lift.
Background technique
Screw lift is that heavy parts is played on a kind of basis, can control exactly by certain procedures and adjust the height that promotes or advance, and can directly drive with motor or other power, also can be manual; Be widely used in the industry-by-industries such as machinery, metallurgy, building, chemical industry, medical treatment, cultural health.Lift is divided into by structural type: 1 type, and leading screw rotates simultaneously and moves axially; 2 types, leading screw rotates, and the nut on leading screw moves axially.Every kind of structural type of lift is divided into again two kinds of assembling patterns: the A type, and leading screw (or nut) moves up; Type B, leading screw (or nut) moves down.
Existing screw lift generally adopts worm and gear to slow down, and rotates by the worm drive worm gear, and the worm gear drives screw mandrel rotates to drive object and does elevating movement, realizes the lifting of object.But the structure of existing screw lift is compact not, and occupation area is larger, and transmission accuracy is not high during work, and the screw mandrel lifting position can not accurately be controlled.
The model utility content
The defective that exists in order to solve existing design, the utility model provide a kind of compact structure, screw lift that occupation area is little.
A kind of screw lift, described lift comprises casing, worm screw, by the worm gear of described worm drive with by the screw mandrel of described worm-gear driven, described worm and wheel is arranged in casing, described casing upper end is fixed with an end cap, described screw mandrel is fixed in the middle of worm gear and through casing and end cap, is provided with oil sealing between described worm screw and casing.
Preferably, described worm gear is connected with casing by clutch shaft bearing, and described worm screw is connected with casing by the second bearing.
Preferably, described end cap is fixedly connected with by screw with casing.
Preferably, the length of described screw mandrel is 200～300mm.
Preferably, described casing one side is provided with oil filler.
The utility model is simple in structure, compact, can save installing space, has simultaneously that transmission stability is good, the precision advantages of higher.
