Definitions

  • the present invention relates to spinning and twisting rings used in textile ring, spirining and twisting machines. More particularly, this invention relates to an improved hard chrome plating technique used on the rings of textile ring spinning and twisting machines.
  • spinning or twisting rings are used to support a traveler that moves rapidly around the circumference of the spinning ring.
  • the ring comprises a flange portion making a track for running of a ring traveler in a sliding contact condition and a mount portion mounted on a ring rail through fitting connection means.
  • the traveler engages and guides the yarn delivering from the drafting zone as it is being twisted and wound onto the tubs mounted downstream on the spindle and the yarn cop built-up takes place.
  • the traveler engages and guides a loose yarn as it is being twisted and wound onto the tube mounted on the revolving spindle.
  • An increase in spinning speed increases the rate at which the traveler rotates around the surface of the spinning ring thereby also increases the centrifugal force applied between the traveler and the ring.
  • the greater centrifugal force increases irictional heating of the ring and the traveler and also increases the abrasive force applied to the ring and the traveler. Due to frequent running at higher speeds, fine vibrations are possibly generated on the ring flange portion at the time of running of a ring traveler and causes the ring traveler and the ring flange portions to undergo abnormal wear and reduces the service life of the ring and traveler.
  • the -hard chrome plating technique revealed in this invention overcomes the above said drawbacks since the hard chrome . plated ring has a low friction coefficient and heat generation at the contact point of ring and traveler is much lesser compared to that of the existing hard chrome plated rings. ' OBJECTS OF THE INVENTION
  • textile spinning and twisting rings are provided with hard chrome plating before usage in ring spinning and twisting machines.
  • the present invention suggests suspension of nanodiamond particles in the electrolyte bath before hard chrome plating. The process is explained in the following description. The trials conducted on the rings with the disclosed method exhibited eminent improvement in the characteristics of the ring.
  • the rings are manufactured using Carbon and alloy steel in any one of the known techniques and are hardened and smooth finished to a surface finish value of less than 0.2 Ra.
  • the rings so manufactured may contain contaminants such as dust, dirt, oil, pigments, grease, fingerprints and so on.
  • the ultrasonic cleaning method uses ultrasound (usually from 20 to 400 kHz) and an appropriate cleaning solution to clean the rings.
  • the ultrasound is not effective without the cleaning solution.
  • the rings are first placed in a chamber containing cleaning solution. Then ultrasonic waves are passed into the chamber through any ultrasound generating means. As a result, the rings are cleaned thoroughly. The surface dirt and contarninants are completely removed. Then the cleaned rings are to be hard chrome plated.
  • the plating process is explained for a sample of 100 lilies of galvanic electrolyte bath.
  • the proportions can be varied based on the suitable ratio for the total volume of electrolytic bath.
  • 100 litres of galvanic electrolyte should be prepared for chrome plating.
  • the electrolyte used is Chromic acid solution.
  • the amount of known chemicals used in hard chrome plating corresponding to 100 litres of chrome plating bath should be dispersed in 70 litres as a concentrated suspension.
  • Nanodiamond (ND) suspension with concentration 50 to 100 grams/litre and total volume of 8 to 10 litres should be dispersed in 20 litres of De-Ionised, water (DI water) by mechanical stirring until an uniform suspension is obtained.
  • DI water De-Ionised, water
  • the well stirred Nanodiamond (ND) suspension is slowly added into 70 litres of the hard chrome plating concentrate and mixed thoroughly in any known method (i.e. mechanically or with air agitation etc.). The above procedure is done before plating.
  • the hard chrome plating is done in usual method after the above said process using Nanodiamond suspension.
  • Nanodiamond suspension For plating, Nanodiamond with purity level 90 to 99 % is. used.
  • the size of single ND particle is in the range of 4 tol 0 nm.
  • the rings exhibit a higher hardness in the range of 1100 to 1400 HV.
  • the thickness of the rings at the inside functional area is found to be 10 to 25 microns.
  • the friction coefficient is below 0.1 which is remarkable and leads to zero running-in.
  • the increased hardness and low friction coefficient will provide a longer life to both the rings and travelers compared to that produced by existing hard chrome plating.
  • the process disclosed overcomes all the disadvantages cited in the background of the invention.
