Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0021] Such as Figure 1 to Figure 7 As shown, a ball screw elevator with a small volume and a large load includes a ball screw nut pair 1, a positioning boss 2, a box body 3, and a worm gear assembly 4 (comprising a worm gear sleeve 401, a worm gear 402, a first spring washer 403, Reaming hole bolt 404), rear cover 5, lock nut 6, first radial ball bearing 7, first plane ball bearing 8, first bolt 7, second spring washer 10, second plane ball bearing 11, Second radial ball bearing 12, gray ring 13, third spring washer 14, screw 15, worm 16, oil nipple 17, fourth spring washer 18, second bolt 19, oil seal 20, tapered ball bearing 21, side end cover twenty two.
[0022] The worm gear assembly 4 and the worm 16 are installed in the box body 3, and the worm gear assembly 4 and the worm screw 16 are meshed and connected. The worm gear assembly 4 is axiall...

The invention relates to a small-size large-load ball screw lift. A worm gear assembly and a worm are mounted in a box body and connected in an engaged mode. A step shaft of a ball screw of a ball screw and nut pair is connected to the interior of the worm gear assembly through a flat key, and the ball screw and nut pair and the worm gear assembly are fixed in the axial direction through a locking nut. The front end and the rear end of the step shaft of the ball screw are connected with a rear cover inner hole fixed in the rear end of the box body and an inner hole in the front end of the box body in a matched mode through radial ball bearings correspondingly, so that radial positioning of the ball screw and nut pair is achieved, and bearing stability of the ball screw lift is improved. According to the worm gear assembly, a worm gear and a worm gear shaft sleeve are connected together in an interference fit mode, the worm gear is made from tin bronze, and the worm gear shaft sleeve is made of steel. The rated static load of the small-size large-load ball screw lift is three or more times that of a traditional ball screw lift identical with the small-size large-load ball screw lift in size, band bearing stability is effectively improved, so that the requirement of the modern science and technology industry for light weight and small size of the ball screw lift is met, and development of the science and technology industry is promoted.
Description
technical field [0001] The invention relates to a screw lifter, in particular to a ball screw lifter with small volume and large static load. The ball screw lifter can be applied to lifting and positioning of equipment such as automobile production, astronomical telescopes, and smelting. Background technique [0002] At present, the ratio of static load to volume of ball screw lifts on the domestic and foreign markets is small. With the increasing development of China's national defense, smelting, aerospace, aviation and other science and technology industries, product design is becoming more and more miniaturized and lightweight, so the requirements for ball screw elevators are becoming more and more miniaturized and large static load. However, the products on the market cannot meet its increasingly sophisticated requirements. At present, the research on the improvement of the static load under the same volume of the lead screw lift is basically an innovation of the applic...
