Three service factors to consider when selecting a Joe type!

When it comes to KTR's representative lineup, the flexible jaw type coupling ROTEX stands out. The selection process is not particularly difficult, but there are safety factors to consider. It is necessary to select a coupling that meets the requirement of motor rated torque * safety factor ≦ coupling allowable torque. This time, I will introduce three points! 1. Ambient temperature ⇒ It is a fact that the heat resistance is lower compared to couplings made of metal, such as gear couplings and disc spring couplings (up to 120°C). The polyurethane spider responsible for power transmission loses its transmission capability as the temperature rises, so a larger safety factor is required. 2. Start-stop and forward-reverse rotation frequency coefficient ⇒ During starting, stopping, and forward-reverse rotation, a large torque is applied to the spider, causing significant deformation of the resin internally. If overload exceeds the allowable value without considering this, it may lead to deformation of the spider, which means damage to the coupling. 3. Load coefficient and application factor ⇒ KTR products are used in various industries, and based on that experience, we establish safety factors for each application.
