SBS81 Series Manual 12
4.5 Servo Motor Drive Belt Replacement
The SBS81 uses a 2:1 reduction timing belt drive to transfer power from the Servo Motor
to the Contact Wheels. This drive incorporates a high-strength Gates Poly Chain GT2
belt, PushCorp Part No. PAR01889-1. Should this Drive Belt ever require replacement,
contact PushCorp for the proper procedure.
4.6 Contact Wheel Replacement
Contact Wheels are not provided with the SBS81, as the user must determine the proper
style and hardness for their specific application. The 14” diameter Contact Wheels are
easily installed or replaced on the SBS81. They are available in different widths (2”, 3”,
or 4”), durometers (hardness), and surface types (plain or serrated). Using different
width Contact Wheels on the SBS81 does not require any modifications to the unit.
Contact Wheels should be ordered directly from the manufacturer, Contact Rubber
Corp., 8635 198th Avenue, Bristol, WI, 53104, Tel: 262-857-2361, Fax: 262-857-9483.
The SBS81 uses C-134 type Contact Wheels. There are four (4) M10x1.5 Flat Head
Socket Screws on the Contact Wheel hub that must be removed to change the Contact
Wheel. After removing the screws the hub will split allowing the Contact Wheel to be
easily removed. Install a Contact Wheel on the hub and replace the removed hub and
the four (4) screws. Tighten the screws to 30 ft.-lbs. (40 N·m).
4.7 Contact Wheel Position Feedback
The SBS81 comes equipped with an internal potentiometer that provides a 0-10 volt
signal based on the linear position of the Contact Wheels. The voltage signal is at a
minimum value when the Contact Wheels are pushed back against the rubber stops,
and a maximum value when the Contact Wheels are pulled forward against the rubber
stops. The total linear compliant stroke is 1.6 in. (40 mm).
The linear position signal must be calibrated for each installation. User calibration is
easily accomplished using the following steps.
1. Turn off the supply air to the SBS81
2. Move the Contact Wheels to the full rearward (negative) position.
3. Read the voltage signal on Pin 13 of the User Interface Connector. Record
this voltage for future reference. This will be referred to as V
neg
.
4. Move the Contact Wheels to the full forward (positive) position.
5. Read the voltage signal on Pin 13 of the User Interface Connector. Record
this voltage for future reference. This will be referred to as V
pos
.
