Abstract
The utility model discloses a universal drive shaft of a continuous coating machine, which comprises a drive rod and a shaft sleeve. The drive rod is in snap fit with the shaft sleeve by matching clamping grooves with clamping blocks. An inner end of the drive rod extends into the shaft sleeve, an outer end of the drive rod can extend outside the shaft sleeve in an axial reciprocation manner, and the shaft sleeve rotates synchronously along with the drive rod. Load balls are arranged inside the shaft sleeve, an outer surface of the drive rod butts against the load balls. By the aid of the universal drive shaft of the continuous coating machine, drive in a rolling manner is realized by the arrangement of the load balls inside the shaft and the application of point-to-point contact between the load balls and the drive rod and replaces the common drive in a sliding manner; by contrast, when the drive rod reciprocates axially, a contact area of bearing friction is small, abrasion is small, service life is long, accuracy is high and the drive is rapid, and stable, so that failure rate of the drive is lowered, equipment activation is improved, product scrapping and capacity loss are reduced.
