Lubrication of ring frame motors in textile spinning

The optimal operation of bearings in a ring frame motor is very critical for the successful operation of any textile spinning mill. Poor lubrication of these bearings would not only result in the stoppages of the ring frames but could also reduce the efficiency of the ring frames during continuous operation. As the ring frame motors contributes to around 45% power consumption in spinning mills, an incremental efficiency of the motor performance would imply huge savings for the users. Optimal lubrication of 4th generation machines with spindlage more than 1632 (1632-1824 spindles ) has also been a challenge for the industry in the past. Improper lubrication of the ring frame motor can add various other challenges for the users like:

• Re-lubrication without removal of machine would leads to grease entering the motor armature, resulting in high probability for motor failure. Resulting rewinding of coils could also cause reduction in motor efficiency by 4.5-5%
• Due to the location of main motor, removal of ring frame main motor would result in a machine stoppage for more than 5 hours resulting in huge production loss
• Poor lubrication would result in additional noise from the motor
• Frequent re-lubrication also adds to higher manpower costs and operating costs

With more than 90 years of experience in developing and manufacturing specialty lubricants, the experts at Klüber Lubrication set out to find a permanent solution for this growing challenge from the Indian market. The solution was attained with the product Klüberquiet BQH 72-102. This low noise high performance grease was also developed to solve all the challenges relating to the lubrication of ring frame motors. A key advantage with the Klüberquiet BQH 72-102 is that it does  not degenerate with electrical discharge which is a common occurrence in the motor bearing. The high speed and temperature resistance property of the grease also ensures that phenomenon like oxidation and blackening of the grease is completely eliminated.  

Extensive tests which lasted for more than 2 years were initially carried out at 3 different spinning mills in India. At these user locations, the product Klüberquiet BQH 72-102 showed reduction in temperature more than 10⁰ C which  directly co-relates to increased efficiency of the ring frame motor operation. Another huge benefit for the user was the increased relubrication interval attained by  Klüberquiet BQH 72-102. The lubricant was able to increase the re-lubrication interval from the 3-4 months interval to an astounding 1.5 years re-lubrication interval. The users were very happy with the results achieved as problems like production stoppage for relubrication, probability for grease to seep into the armature coil and reduced efficiency was completely eliminated.  The high speed “quiet” operation property of the lubricant is also an additional feature which was well appreciated by the users during the extensive trials.

Mr Pramod Almore- Head of Textiles Klüber Lubrication India Pvt Ltd says “It really gives a great satisfaction to see a delighted customer who has come out from the perineal problem of motor bearing lubrication. Continuous increase number of fan following for Kluberquite BQH 72-102 is irrefutable evidence of success of this unprecedented revolutionary solution, the customer not only gets higher performance but also saves more than Rs. 1 million in their operating costs”.

• Longer relubrication interval of about 1.5 years.
• Higher efficiency of operation due to reduction in operating temperatures of the Ring frames motor bearings.
• Lesser initial torque and lower noise
• Cleaner motor armature due to lesser re-lubricantion
• No electrical erosion in the bearings
• Lesser operating and manpower costs.
• Improved electrical conductivity for motor equipped with inverters.
