| Belt Technologies,
Inc. designs and manufactures pulleys specially engineered to run in
conjunction with stainless steel belts and tapes. Pulleys can be
constructed to insure accurate positioning, repeatability and drive
performance. Features such as timing elements, relief channels and
the selection of materials are considered to maximize the
performance of the application. All pulleys are designed with
keyways or shaft locking assemblies for integration with drive or
idler shafts. |

Friction Pulleys
Friction pulleys are a simple, low cost solution for driving metal
belts and maximizing belt life. Pulleys are typically made of
aluminum and hard coated for a wear resistant surface. Stainless
steel for chemical resistance and plastic composites for weight
considerations can also be used. I-Beam and Capped Tubed
pulleys are used on friction belts when the weight of the pulley
would adversely affect the rotational inertia of an aggressive
precision position indexing motion. |

Timing Pulleys
Timing pulleys are used when a motion system needs to deliver
precise positioning accuracy and repeatability. Pulleys are
typically aluminum and hard coated for wear resistance but other materials are available. Belt Technologies features two types of
timing pulleys. |

 |
|

|
|
|
Type 1 Timing
Pulley features a patented (#5,129,865) spherical timing tooth
which protrudes from the surface of the pulley and engages in a
belt perforation. An involute tooth may also be used for
engagement. |
|
Type 2 Timing
Pulley incorporates a timing pocket into the pulley which
engages with a physical component on the inner circumference of
the metal belt. |

Independently
Steerable Pulleys
For ease of tracking Belt Technologies has developed a pulley
that independently steers flat belts (Patent Numbers 5,427,581
and 5,676,613). Belts are steered by the changing tension
relationships across the width of the belt by adjusting the
angle of the pulley relative to the belt. Rather than moving the
pulley shaft left/right of up/down by pillow block adjustments,
the ISP designs fit a variable steering collar and sealed
bearing assembly to |
| the body of the
pulley. The steering collar is designed with either a skewed
or an offset bore. When rotated, the collar changes the angle
of the pulley body, resulting in the controlled bi-directional
movement of the belt across the pulley face. Please contact a
Sales Engineer for more information. |

Low Inertia
Pulley
Belt Technologies manufactures a Low Inertia Pulley. With up
to a 60% weight reduction of a normal pulley design the
inertia required to start, stop or index a system is
dramatically reduced. The pulley design incorporates the use
of a thin stainless steel surface for reduced weight. Pulley
ends are finished with stainless or aluminum caps depending
upon the application. The ends may be machined to further
reduce weight. |
