Shock Guard TGE Series

A type that allows for a wide range of torque settings with the same size
- Bearings are used and the center member is attached to the bearing, so runout is smaller than that of the TGB series.
- You can choose between Type 1, which can be fitted with small diameter sprockets and wide pulleys, and Type 3, which can be fitted directly with A-type sprockets and pulleys.
- After removing the cause of the overload, simply rotate the drive side and the gears will automatically re-engage.
- The arrangement of the balls and pockets that serve as torque transmission elements is a unique combination that only meshes in one place.

Operating principle

Please watch the animation to see the operating principle of the TGE series.

During normal operation (engaged)

With the TGE series, power enters through the hub and is transmitted to the output drive plate via the drive balls (or vice versa).

Sprockets and Belt Sprockets are attached directly to this drive plate with bolts.

There are holes in the flange of the hub that fit several drive balls, and the drive balls are arranged in these holes.
The drive plate on the output side has pockets for the drive balls, which are compressed by a coil spring through a thrust race to transmit power.

When overloaded (tripped)

When an overload occurs, the drive ball pushes the thrust race up towards the coil spring, and the drive
It pops out of the pocket in the plate and cuts off power.

At this time, the cover moves toward the coil spring, and by detecting this movement with a TG sensor, etc.,
After an overload occurs, the drive source can be automatically stopped easily.

Reset method

After an overload, if you restart it, it will automatically return to its original position within one rotation.

The TGE series will continuously reset if rotation continues after operation, so after an overload occurs, detect the overload with a TG sensor or similar device and immediately stop the drive source.

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.

Torque adjustment

1. Read the nut height value corresponding to the required torque from the torque correlation diagram, and tighten the adjustment nut to this value (see diagram below).
To tighten the adjustment nut, loosen the set screws in two places, then place a hook wrench (see table below, sold separately) in the notch on the outside of the adjustment nut and turn it.
The torque of the product does not necessarily match the correlation diagram below, so please use it as a guide.

Hook wrench
size	TGE25	TGE35	TGE50
Spanner No.	FK-0070	FK-0092	FK-0105

2. Once the torque has been determined, you can add that value to the nameplate, so that even if you disassemble the product for maintenance, you can easily return to the previous set torque.
In addition, you can make the reproduction more accurate by stamping a match mark on the end face of the hub on the nut.
