Driven Pulley: Bore Size 10-100 mm, Diameter 50-500 mm

Component Specifications

Definition

A driven pulley is a mechanical component in belt drive systems that rotates when engaged by a moving belt, transferring torque and rotational motion from the driving pulley to connected shafts or mechanisms. It functions as the output element in the transmission system, converting belt motion into useful mechanical work.

Working Principle

The driven pulley operates on friction-based power transmission principles. When the driving pulley rotates, it moves the belt, which engages the driven pulley through frictional contact. The belt's tension creates sufficient grip to rotate the driven pulley, transmitting torque without slippage. Speed ratios are determined by the diameter difference between driving and driven pulleys.

Materials

Typically manufactured from cast iron, steel alloys, aluminum alloys, or engineered plastics. Common specifications include: ASTM A48 Class 30 cast iron, AISI 1045 steel, 6061-T6 aluminum, or polyamide (PA) with fiber reinforcement for specific applications.

Frequently Asked Questions

What is the difference between a driving pulley and a driven pulley?

A driving pulley is connected to the power source (motor/engine) and initiates motion, while a driven pulley receives motion from the belt and transmits it to other components.

How do I select the correct driven pulley for my application?

Consider belt type, required speed ratio, torque transmission needs, shaft diameter, operating environment, and material compatibility with your specific industrial application.
