Abstract
A tape idler for textile machinery includes a pulley, and a rolling bearing pressfit into the pulley. A pair of plastic rods are close fitted into the inner race of the bearing, from opposite sides thereof, and the assembly is held together by a bolt extending through the rods. A pair of resilient sleeves are close fit on the ends of the rods, and adapted to be pressed into the mounting slots of a conventional idler pulley assembly.
Claims8
A tape idler pulley assembly adapted to be supported in open mounting slots, comprising a pulley, a rolling bearing having a radially outer race press fit in said pulley and an inner race, a pair of plastic rods having first ends close fitted in the inner race of said bearing from opposite sides thereof, and a pair of resilient sleeves close fit around the other ends of said rods, said sleeves having a diameter requiring deformation thereof for insertion in said mounting slots.
A kit for reducing the noise produced by a tape idler pulley assembly adapted to be mounted in open rectangular slots, said assembly having a pulley, first and second cover plates on opposite sides of the pulley, each cover plate having a rectangular projection adapted to fit one of said slots, and a rolling bearing held between said plates for rotatably supporting said pulley, said kit comprising a pair of plastic rods, and a pair of resilient sleeves having inner dimensions to closely fit said rods and outer dimensions to closely fit into said slots, whereby said sleeves and rods serve as replacements for said plates.
