The structure is composed of polyurethane timing belts with back,
tensile layers, with teeth of three parts.
(1) PU belt back
Belt in the back for the tensile bond-coated components, should
have good flexibility and flex fatigue resistance music, not easy
to aging, oil resistance, good wear resistance, in the band back to
open the inner surface of the appropriate size of the cusp grooves,
in addition to due process requirements, but also to improve the
tooth with a curved flex fatigue performance, while running the
process, to bring closure with the air escaping between the teeth
in order to eliminate some of the noise.
(2) steel wire rope (or polyester cord) tensile layer
Tensile tensile layer is synchronous components to deliver power,
and to ensure that spring from the same belt at work. It uses
multi-strand steel wire rope (or polyester cord) along the tape
width of the spiral-shaped manner around the cloth, its position as
the belt line of the festival. Tensile layer must have a high
tensile strength and resistance to bending fatigue strength.
Elastic modulus and working hours are not allowed elongation, in
order to ensure the pitch timing belt change.
(3) PU belt teeth
Polyurethane synchronous belt tooth should have a higher shear
strength, good wear resistance and oil resistance. The distribution
of the pitch with a very high gear, with teeth should mesh with the
pulley alveolar correct, and therefore the correctness of geometric
parameters with teeth, there are strict requirements needed. PU
belt with excellent oil resistance, wear resistance, claiming it
applies to small and medium-power high-speed operation with the
occasion, the environment should be relatively dry, the working
temperature is generally -20 ~ +80 C.
Polyurethane ring belt is the driving force produced through a
special molding process.
High-quality polyurethane material so that belt resistant to wear
and tear resistant properties.
One of the core wire to increase belt strength, tensile strength,
so that belt has good dimensional stability.
Polyurethane ring power band, tolerance is small, can guarantee the
accuracy of the thickness and length.
All of the above characteristics make polyurethane ring with a high
dynamic physical and chemical stability.
PU Seamless Timing Belt for high strength, high accuracy as well as
Polyurethane belt has the following properties:
- Dimensional Stability - Pre-Rally Low - low noise
- Highly resistant to wear - no need to maintain - good elasticity
- Linear speeds up to 80 m / s
- Anti-aging, water solution, UV-UVA, anti-ozone
- Operating Temperature: -30~ +80short period of time can withstand
the highest +110
- A high degree of anti-oil, anti-oil ester
- The majority of anti-acid and alkali corrosion
PU Seamless Timing Belt grade most suitable for low-load
synchronous transmission, such as office automation systems and
