Installation & Maintenance for Rolling Ring Linear Drives

Installation of traverse unit (rolling ring drive):

Mounting the Shaft:
To prevent the shaft from being blocked by the dustproof sheath at the both ends of the traverse unit housing when mounting the shaft, you shall adjust the sheath hole first, and then put the release lever in released position before the shaft is, in series, put through the deadeyes of several bearings inside the traverse housing, and finally put the release lever back in the working position.

Determining Direction of Rotation:
The downward turning of the shaft of rolling ring drive when facing the scale dial is defined as the positive rotation, in which case the trigger roller of the reversal arm shall point to the side where the scale dial is. While the upward turning of the shaft when you looking in front of scale dial is reverse rotation and in such case the trigger roller of the reversal arm shall point to the backward side of the traverse unit housing so that the reversal of the traverse drive can be realized. The product is normally assembled with the shaft turning positively when leaving the factory.

Rotation Speed of Shaft:
The take-up bobbin speed shall be higher than the traverse unit shaft speed. The speed ratio available ranges from 5:1 to 1:1. If the wire size is small the ratio will be large and If the wire size is large the ratio will be small. 

Traverse Travel:
Adjust the positions of two reversal end stops on the lead screw to make the reciprocating travel match the position and length of the take-up bobbin.


Installation of rolling ring linear drives

Maintenance of traverse unit:
Pay attention to the dustproof work in the working environment. The #20 machinery oil should be applied to the shaft to keep a certain film of oil on the working surface. The running part of the reversal springs should be lubricated for protection.

Reversal Failure:
In case the reversal is too show or not available, push and check the reversal arm for swivelling blockage so as to eliminate the fault. If the elasticity is insufficient, change the reversal spring and lubricate the bearing point of spring.

Inadequate Thrust:
Adequately screw clockwise the screw plugs in the center of the top and/or in the side edge of the bottom of the drive housing until the traverse thrust required is available. Too tight adjustment of screw plugs often causes improper reversal and may lower the operating life of the drive unit.

Uneven Traversing:
The eccentric sleeve on the back side wall of the housing is required. It is usually fastened by set screws. Loosen the screws first to make a slight adjustment, and screw them tight again after the left-handed and right-handed travel pitches are identical.
