Abstract

The invention relates to a worm wheel spiral elevator. The worm wheel spiral elevator comprises a worm rod, a convex worm wheel, a guide pin, disc springs, a screw rod, a bearing, a box body, a concave worm wheel, a screw, a guide key, a locking nut and a second bearing, wherein the disc springs are arranged in middle grooves of the convex worm wheel and the concave worm wheel; the guide pin and the locking nut are arranged at the periphery of the outer side; one side of the convex worm wheel is connected with the box body by a first bearing; one side of the concave worm wheel is connected with the box body by the second bearing; the screw rod is arranged in the box body, the convex worm wheel and the concave worm wheel; the convex worm wheel and the concave worm wheel are engaged with the screw rod. The invention provides a micro-backlash transmission mechanism capable of eliminating transmission errors in a transmission system.

Description

technical field [0001] The invention relates to a worm gear screw lifter, in particular to a roll gap adjustment device of a straightening roller of a straightening machine. It is used for the adjustment of the roll gap size of the plate straightening machine and the roller angle adjustment mechanism of the skewed roll straightening machine. Background technique [0002] The existing inclined roller straightening machine adopts the angle adjustment mechanism of the link mechanism and the roller gap adjustment mechanism of the plate leveling machine: the roller gap can be raised and lowered by changing the screw stroke of the worm screw elevator installed on the frame; or In the angle adjustment device of the skewed roller straightening machine, the angle of the straightening roller can be changed by changing the length of the extended screw of the worm gear screw lifter. The modern straightening machine is a highly mechatronic equipment, and the actual variation of the adju...
