What quality tests are performed before shipment?

All drums undergo static balance tests, and welds undergo non-destructive testing. Hub casting quality is checked via magnetic particle or ultrasonic testing.

What is the guaranteed fatigue strength of the pulley?

The pulley, including welding parts, is guaranteed to have a rotational fatigue strength of over 10^8 cycles.

Product Q&A

Q:What is the maximum belt width and tension the pulley can handle?

The pulley can handle belt widths up to 2.4 meters and maximum tension up to 300 tons.

Q:What materials are used for the pulley pipe and shaft?

The pulley pipe is made of Q235B carbon steel with high roundness. The shaft uses 45# round steel or custom requirements, treated with quenching and tempering.

Q:What surface treatment options are available?

Options include smooth, rubber lagging, or ceramic rubber lagging. Adhesive treatments include coal bonding or hot vulcanization.

Q:What is the static balance accuracy of the pulley?

The pulley achieves a static balance accuracy of G40, with total radial runout of the outer circle less than 1mm after roller casting.

Q:How is the connection between the drum hub and shaft achieved?

For medium and heavy-duty pulleys, expansion sleeves are used to connect the shafts and wheels, solving stress concentration issues.
