Shock Guard TGX Series

High precision type with no backlash and excellent rigidity under normal conditions
- The original ball-and-wedge mechanism eliminates backlash.
- Even with the same size springs, different color-coded springs allow you to set different torques.
-Lost motion during tripping is extremely small.
-The ball and wedge arrangement is a unique combination that only fits together in one place.
- The non-contact TG sensor detects overload and can stop the motor or issue an alarm.
-TGX coupling type is also available.

Structure

Operating principle: Ball and wedge mechanism (PAT.)

During normal operation (engaged)

Torque is transmitted from the hub to the drive ball (steel ball) and then to the driven flange (or vice versa).

The drive balls (steel balls) are held in place by the pressure of the coil spring on the hub and driven flange.
The contact area with the drive ball (steel ball) is tapered, and the drive ball (steel ball) is always held in place by the V-shaped retaining part of the hub.
The gap is set to 0.

This mechanism is the ball and wedge mechanism (PAT.).

When overloaded (tripped)

When overloaded, the drive balls (steel balls) rise from their pockets and begin to roll.

There are no sliding parts and it is all rolling, so the idling friction torque is very small and it has excellent durability.

The drive ball (steel ball) Auto reset to its original pocket when operation resumes.
As with the TGB series, the five drive balls (steel balls) and pockets are unevenly arranged, so they always come in at one place.
There is no meshing or phase shift.

TG sensor

This is a proximity switch type overload detection sensor designed specifically for Shock Guard. It can detect an overload on Shock Guard (movement of the plate in the axial direction) and stop the motor or issue an alarm.
