Shock Guard TGH Series
- This type can be attached to a high-speed rotating shaft such as a direct motor connection, and is also compatible with high torque.
- - Repeated operating torque accuracy is within ±5%.
- In addition to the basic type, we also stock coupling and pulley types.
- - This function does not Auto reset, so after tripping due to overload, the rotation of the drive side is not transmitted to the driven side.
- -You can choose between one-position return (returning in only one position) or random return.
・One-position return: Always returns to a fixed position. Suitable for phase alignment.
・Random return: You can return regardless of your position.

Operating principle
Normal (engaged)
In the TGH series, several drive balls (steel balls A) are sandwiched between a drive plate and a slide plate, and power is transmitted while being pressurized by a spring.
Power enters through the hub, is transmitted to the slide plate which meshes with the involute spline, and is then transmitted to the drive plate via the drive balls (steel balls A).
The driven pulley and coupling are fixed to the adapter attached to the drive plate with spring pins and bolts.
When overloaded (tripped)
When an overload occurs, the drive balls (steel balls A) push the slide plate toward the spring, and while rotating, they jump out of each pocket on the drive plate, cutting off power.
After this, if the drive ball (steel ball A) continues to spin freely, it will enter a deep pocket in the slide plate, and steel ball B on the intermediate plate will support the spring load applied to the slide plate.
As a result, the drive ball (steel ball A) remains stuck in a deep pocket in the slide plate, and even if it continues to spin freely, it does not transmit power to the drive plate and continues to spin freely.
