Product Brief Introduction
we can provide a wide range of smooth shaft(rolling rings) traverse
drives with different types,which can meet various requirements of
our customers.among our products,the types PX15-PX30,with housings
of aluminium alloy,have 3-frame and 4-frame models respectively,the
thrust force of the 4-frame model doubling that of the 3-frame one.
PX40 and PX50 have 2 models,one with the aluminium alloy housing
and the other with the cast iron one. And PX60 is of the cast iron
housing. The housings made of cast iron have good rigidity and
reliablepositioning,being applicable to the applications which are
under the severe environmental conditions and require large thrust
The rolling ring linear drives provided by us are characterized
wuth a lot of features such as the stepless speed adjustment,the
instantaneous reversal, the Drive position adjustment just by means
of the release lever,the special treatment of the Smooth Shaft,the
Traverse Drive being mounted with selected high performance
bearings,and long service life.
Installation and Debugging
Release Lever. There are two positions,i.e, the working position "1" and the
releasing position "0". When the lever sits at the working
position,the bearing above it are at the lifting position and apply
pressure to the Smooth Shaft and so make the Traverse Drive
generate the thrust force.when the lever sits at the Releasing
Position,the earings above it are at the falling position and by
pushing with hands you can make the Traverse Drive slide freely on
the Smooth Shaft.Before install the Smooth Shaft,pull the Release
Lever and check if the bearings can be moved up and down.
Mounting the Smooth Shaft By putting the Release Lever at the released position"0" and
adjusting the sheathes at the both sides of drive you can install
the shaft into the Traverse Drive,and then pull the Release Lever
to the working position"1"
Adjusting the Guide Roller The Guide Rollers can be used to ensure the working stability of
the Traverse Drive.The Guide Frame is eccentric.when the space
between the Guide Roller and the Guide Bar is not
correct,adjustment can be made by loosing the screws and turning
the Guide Frame.
Determining Direction of Rotation The downward turning of the shaft when facing the scale dial is
defined as the positive rotation,in which case the trigger roller
of the reverseal 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 housing so that the reversal of the traverse drive can be
realized. The roduct 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 shaft speed of
the traverse drive.The speed ratio available ranges from5:1 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.
Pitch Adjustment The scale values 1-10 on the dial are the adjustment range of
pitches,and not the numeric value of pitch.The pitch is matched to
the thickness of the wire/cable.when the Indicator is at the left
of the Scale Dial,the Traverse Drive dwells on the Shaft without
any movement.in addtion,the adjustment should not be made to the
maximum pitch position.when adjustment is made the Indicator shall
be disengaged completely from the Serrated Scale Dial.
Mounting the wire Guide Pulley/Roller When mounting the wire part special care should be taken not to
turn the screw too deeply into the box,in order to avoid influence
the normal working conditions of the internal mechanism.
Traverse Travel Adjust the positions of two reversal end stops on the lead screw
to make the travel match the position and length of the take-up
Maintenance 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 slow 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 lubricated 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 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's 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.
