HTB® High-Torque Belts - 3M, 5M, 8M, 14M
Curvilinear Tooth Profile
(Oil, Heat & Abrasion Resistant)
The standard trapezoidal tooth timing belt design performs poorly in in high-torque
applications and high-power drives at lower speeds. To overcome this disadvantage, the
High-Torque Belt (HTB®) was developed using a more efficient tooth profile.
Among the advantages are:
l
Higher torque transmission at low speeds
l
High power transmission over a wide speed range
l
Improved meshing to reduce tooth jump
l
Higher resistance to tooth shear
l
Less tooth wear due to friction
A.
A high-modulus fiberglass cord is wound across
the entire width of the belt pitch line ensuring
minimal stretch and resistance to repeated flexing.
B.
The body is a synthetic chloroprene compounded to
resist flex fatigue, heat, ozone, mineral lubricating
oils and aging.
C.
A tough nylon fabric is bonded to the tooth surface
for wear resistance.
Stock 5mm, 8mm and 14mm pitch HTB® Synchronous Belts
are listed below. Non-standard lengths in these pitches are
also available, as are belts with 3mm pitch.
3M - 3mm HTB® Synchronous Belts
Many lengths are in stock and can be cut to the desired
width. Additional 3mm pitch HTB® Belt sizes are available on
a made-to-order basis. Please check with Jason/Megadyne
for availability. HTB® Synchronous Belts are specified by belt
pitch length, tooth pitch and belt width in millimeters.
Example: 720-8M-30
720-8M-30
720 =
Belt pitch length in millimeters = 720mm
8M =
Tooth pitch in millimeters = 8mm
30 =
Belt width in millimeters = 30mm
