Abstract
The invention provides a ball screw lifter which comprises a body. A worm gear and a worm are disposed in the body. The worm gear is meshed with the worm. The worm gear is rotatably connected with the body through a bearing. A bearing cover is disposed outside the bearing. A coupler is disposed at one end of the worm. The other end of the worm is provided with the inner toothed ring of a crowned-tooth coupler. An outer gear is disposed on the inner toothed ring of the crowned-tooth coupler. A ball screw is disposed in a worm gear hole. A copper sleeve is disposed between the worm hole and the ball screw. A slide sleeve is disposed on the ball screw and located below the copper sleeve. A shaft end retaining plate is disposed on the lower portion of the slide sleeve. A dustproof cover is disposed on the bearing cap. A screw end cover is disposed on the dustproof cover. A lifting block is disposed between the screw end cover and the ball screw. The screw end cover and the ball screw are connected through a connecting sleeve. The ball screw lifter has the advantages that the worm drives the worm gear to rotate, the worm gear drives the ball screw to move up and down, an heavy object is lifted by the screw end cover on the ball screw, and the ball screw lifter is simple in structure, convenient to use, high in transmission efficiency, and the like.
Description
Technical field
The invention belongs to elevator field, especially relate to a kind of ball screw elevator.
Background technology
Screw lift is that one electrical motor or other power directly drive, and makes the machine that screw lift is placed promote or decline.Screw lift is widely used in the industry-by-industries such as machinery, metallurgy, building.In existing technology, screw lift generally adopts worm gear and cliding friction type leading screw to carry out transmission, there is the technical matters that in transmission process, between silk worm and wheel, friction force is large, driving efficiency is low.
Summary of the invention
The problem to be solved in the present invention is to provide the ball screw elevator that a kind of structure is simple, driving efficiency is high.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of ball screw elevator, comprise body, worm gear and worm screw, described body is provided with cover, described worm gear and worm screw is provided with in described body, described worm gear and worm mesh, described worm gear is connected by bearing rotary with body, bearing cap shim is provided with outside described bearing, one end of described worm screw is provided with coupler, the other end of described worm screw is provided with the internally toothed annulus of crown gear coupling, the internally toothed annulus of described crown gear coupling is provided with external gear, ball screw is provided with in described worm wheel aperture, copper sheathing is provided with between described worm wheel aperture and ball screw, the below that described ball screw is positioned at copper sheathing is provided with sliding sleeve, the bottom of described sliding sleeve is provided with axle end baffle plate, described bearing cap shim is provided with dust boot, described dust boot is provided with screw mandrel end cap, jacking block is provided with between described screw mandrel end cap and ball screw, described screw mandrel end cap is connected by adapter sleeve with described ball screw.
Further, hood is installed, for protecting body and lubrication at described underpart.
The advantage that the present invention has and good effect are: owing to adopting technique scheme, and worm screw drives worm gear to rotate, and worm gear drives ball screw to move up and down, and lift heavy thing by the screw mandrel end cap top on ball screw; Have that structure is simple, easy to use, driving efficiency advantages of higher.
