Abstract

The invention provides a nylon roller sheath with self-lubricant function, high strength, and long service life, used in cam swing device of loom, wherein, the invention is formed by 85-93% aminocaprolactam, 2-5% sodium-hydroxide additive, and 5-10% mineral oil. The invention also discloses a method for producing roller sheath, for resolving the abrasion problem, with low cost and simple production.

Description

technical field [0001] The invention relates to a textile machine part and a manufacturing method thereof, in particular to an oil-containing nylon roller cover for a cam swing arm transmission mechanism of a warp knitting machine and a manufacturing method thereof. Background technique [0002] The cam swing arm link transmission mechanism is an important transmission part in the warp knitting machine, and its performance and life directly affect the performance of the warp knitting machine. At present, the traditional cam swing arm linkage transmission mechanism is composed of main shaft, cam, swing arm, connecting rod, roller and other components. The main shaft drives the cam to rotate. The end of the arm where the roller is installed moves up and down regularly under the drive of the protrusion, so that the connecting rod installed on the swing arm moves up and down, and then the connecting rod drives the corresponding knitting mechanism to realize the predetermined kni...
