Customised nuts and attachments for lead screws
Abssac has long supplied cold rolled formed stainless steel lead screws and anti-backlash nut designs, and now offers the facility to have non-standard attachment designs incorporated
As the machine operated within a food grade environment meant there could be no lubrication with the system, which contributed to the premature failure of the nuts after only 50,000 cycles.
It was also a concern that the existing lead accuracy matching between leadscrews could also be a factor in the excessive wear of the nuts.
By using a PTFE impregnated plastic as the antibacklash nut base material and ensuring matched pitch accuracy of the screws in both the right handed and the left handed screws enabled initial tests cycles up to 56,000 cycles to be completed without any sign of wear to the nuts.
Chris Cattle of Abssac says: "By being able to match the screws pitch accuracy reduces the stresses within the system considerably, ensuring a more reliable linear movement". Request a free brochure from Abssac ...
