Worm gear and worm reducer transmission device

Abstract

The invention relates to a worm gear and worm reducer transmission device which is particularly suitable for knitters. The worm gear and worm reducer transmission device comprises a box body (1), a box body cover (2), a worm gear (3), a worm (4), a worm gear shaft (5) and a worm shaft (6). The two ends of the worm gear shaft and the two ends of the worm shaft are provided with end covers (7) for fixing the worm gear shaft and the worm shaft to the box body, and the end covers are internally provided with bearings (7-1) and sealing rings (7-2). The box body cover is connected to the upper side of the box body, and an oil injection hole (2-1) and an oil injection stopper (2-2) are arranged on the box body cover. One end of the box body is provided with a boss (1-1), the boss is provided with a through hole enabling a knitter stand column (8) to penetrate through, the side face of the through hole is further provided with a connecting piece (1-1-1) to connect the whole box body to the stand column, the worm and the worm shaft are in clearance connection, and the side face of the worm is provided with a connecting piece (4-1) to connect the worm and the worm shaft together. The worm gear and worm reducer transmission device is small in size and capable of moving up and down along the stand column, the service life of the reducer is prolonged and the density of knit products can be conveniently adjusted.

Description

technical field [0001] The invention relates to a transmission device of a worm gear reducer, which is particularly suitable for the transmission device of a worm gear reducer of a knitting machine, and belongs to the technical field of knitting machinery. Background technique [0002] The knitting machine is a kind of mechanical equipment used for knitting machine ropes, fishing lines, wires, fishing net lines and other products. Most of the transmission and reduction devices on the existing knitting machines adopt the dry meshing type of worm gears, such as figure 1 As shown, there is a worm gear bracket 10 on the knitting machine, the worm gear bracket 10 is connected with the worm gear shaft, the worm gear shaft is connected with a worm gear 30, the worm gear 30 is engaged with the worm screw 40, and the worm screw 40 is connected with the transmission shaft 50, and the whole device is installed on On the column 20. During work, the transmission shaft 50 of the knitting...

AI Technical Summary

Problems solved by technology

[0003] The dry-meshing worm gear reducer cannot be filled with oil, so it cannot run at high speed, and the work efficiency is low; at the same time, the worm gear transmission resistance is large, the wear is serious, and the service life is short; this transmission method is not easy to adjust the product density, which in turn affects the weaving efficiency and quality
