Example of Use
Example drawing of a workpiece reversal transfer mechanism designed using MISUMI timing pulley
■Mechanism name
Workpiece reversal transfer mechanism

■ Mechanism function
Rotates the workpiece on the conveyor belt by 90 degrees and transfers it to the next process.
At this time, the clamping mechanism rotates 180 degrees and does not change the direction of the workpiece relative to the conveying direction at the same time during transfer.

■Role of the Timing Pulley
The transmission of the timing pulley and the timing belt changes the placement direction of the workpiece while transferring the workpiece. (Applicable to S specification and GT specification timing pulleys)

Frequently asked question (FAQ)

Question: Why does the flange drop during use of a timing pulley?
Answer: The function of the flange is to prevent production accidents caused by deviation and drop of the timing belt. Therefore, the flange drops mainly because it is squeezed off by the timing belt that has deviated for a long time. We recommend that the customer regularly check the condition of the timing belt of the equipment to avoid its deviation.
Question: Why does the timing pulley has no threaded hole?
Answer: If you have requirements for fixing screws, we recommend that you choose a timing pulley with the shaft hole specification P (round hole + threaded hole) or N·C (keyway hole + threaded hole).
Question: What should be done if there is jitter during use of a timing belt?
Answer: Readjust the tension of the timing pulley. Generally, the belt runs unstably due to excessive shaft spacing and insufficient tension.
Question: Why cannot be the threaded hole of a MISUMI aluminum timing pulley locked tightly?
Answer: As the aluminum material is relatively soft, slippage may occur if the tightening force is too large during locking. We recommend that the customer stops tightening once an obstruction is felt.
Question: How to fix a timing pulley when the shaft hole specification is H (round hole)?
