Mechanical overload protection device "Shock Guard TGX Series"
High precision, high rigidity, and non-backlash mechanical protective device excellent for high-precision positioning.
"Shock Guard TGX Series" The Shock Guard TGX Series is a device that relieves overload by allowing the drive ball to rotate and slip when torque exceeds the set limit. TGX offers higher precision and superior rigidity, making it suitable for applications such as high-precision positioning. By clicking on the <Tsubaki Power Transmission Comprehensive Technology Site - Shock Guard TGX Detail Page> below, you can view detailed product descriptions. You can also check for new part numbers, software for replacing old part numbers with new ones, automatic drawing services, user manuals, 2D CAD & 3D CAD, selection and troubleshooting, etc. <Part Number Change> A part number change was implemented from April 2018. The shaft hole diameter is available in millimeter increments, with a total of nine types of shaft hole tolerances, four types of keyway tolerances (new JIS and old JIS), and the position of set screws can be selected from up to nine types, achieving over one million combinations.
basic information
**Features** - High Precision Trip The lost motion during the trip is extremely small, allowing for high-precision trips. - Automatic Reset If the cause of overload is resolved, the driving side will automatically re-engage and return to its original state. - One Position Type The arrangement of the balls and pockets, which serve as the torque transmission elements, is unevenly distributed, resulting in a one-position engagement. - Easy Torque Adjustment By simply turning the adjustment nut (bolt), you can freely adjust the trip torque. - Coupling Function In a coupling type, misalignments such as angular errors, parallel errors, and axial displacements are absorbed by the ball & wedge mechanism. - No Backlash Thanks to the innovative ball & wedge mechanism, there is absolutely no backlash.

Applications/Examples of results
[Precision Machinery and Medical Equipment] - For X-ray drive, TGX detects overload when the X-ray rotates and protects the machine. - In the event of a paper jam in a small precision printing machine, it also detects overload and protects the machine by slipping into idle.
Detailed information
-
Application Example 1: Compact Precision Printer Even when a paper jam occurs in the compact precision printer, it detects the overload and protects the machine by slipping into idle mode.
-
Application Example 2: Machining Center Drive Unit This is a mechanism that prevents damage to the cam and deformation of the gripper when there are obstacles during the rotation of the gripper or when the retrieval set does not operate properly, causing the TGX to trip.

Our company, as a member of the Tsubakimoto Chain Group, is dedicated to providing solutions that meet our customers' needs, focusing our business on three main pillars: chains, precision machinery products, and conveyor systems. In April 2012, we reorganized within the group, and our chain business restarted with a focus on the Tsubaki brand's top chain operations. In recent years, driven by energy conservation and cost reduction, engineering plastic chains have become widespread in various applications that replace traditional conveyor systems, with increasing demand not only domestically but also internationally. The need for products that can withstand harsh operating conditions is also growing, making it increasingly important to provide solutions through optimal products and appropriate engineering services. In this context, we have significantly revamped our structure to consolidate the group's strengths and enhance functionality and efficiency. Our production base, the Kuki Factory, underwent extensive renovations, greatly increasing production capacity, and we completed a new factory building in March 2013. We sincerely thank you for your long-standing support and ask for your continued guidance and encouragement in the future.
