You selected the right AGMA Class gearbox . You calculated the belt tension perfectly. But the moment you hit "Start," the belt snaps or the gearbox makes a terrifying clunk. The culprit is likely your Starting Method . In conveyor systems, the starting torque profile matters more than steady-state power. Note: We previously discussed VFDs as Energy Savers for pumps and fans. For conveyors, however, the goal is not lowering your electric bill—it is preventing your gearbox from exploding.

The Physics of Shock Loads When an AC induction motor starts Direct-On-Line (DOL), it draws 600% to 800% of its rated current (Inrush Current). More importantly, it produces a sudden spike known as Locked-Rotor Torqu...
Timing belts solve the slippage problems inherent in flat, O-ring, and V-belts by utilizing a flexible tooth molded to a belt with internal tension members. These teeth are flexible, allowing the load to be distributed across all teeth in contact with the pulley, ensuring precise power transmission. Advertisement Timing belts belong to a larger category of power transmission devices known as synchronous drives . Unlike friction-based drives, these belt or cable-based systems have the distinct advantage of zero slip . This "positive drive" capability means these belts perform reliably even in wet or oily conditions, provided the pulleys are made of corrosion-resistant materials like stainless steel or plastic. Figure 1: Timing belts maintain an exact speed ratio, crucial for engines and automation. Tooth Profiles: The Evolution of Design Timing belts are categorized by their tooth profile and manufacturing method....
