Mechanical overload protection device "Shock Guard TGB Series"
Easy installation and a wide variety of general-purpose mechanical protection devices.
<Shock Guard TGB Series> The Shock Guard TGB Series is a device that relieves overload by allowing the drive ball to ride up from the pocket section and spin freely when torque exceeds the set limit. This effectively protects the safety of machinery. The TGB Series offers easy operability and an affordable price, making it suitable for various applications as a general-purpose type. By clicking on the <Tsubaki Power Transmission Comprehensive Technical Site - Shock Guard TGB Detail Page> below, you can view detailed product descriptions. You can also check for new model numbers, software for replacing old model numbers with new ones, automatic drawing services, user manuals, 2D CAD & 3D CAD, selection and troubleshooting, etc. <Model Number Change> Model number changes were implemented from April 2018. The shaft hole diameter is compatible in millimeter units, with a total of nine types of shaft hole tolerances, four types of keyway tolerances based on new JIS and old JIS standards, and the position of set screws can be selected from up to nine types, achieving over one million combinations.
basic information
**Features** - Wide Variation A broad lineup of 58 sizes available from 0.3N·m to 7,150N·m. - Automatic Return By removing the cause of overload and simply rotating the drive side, the drive side automatically re-engages and returns. - 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 You can easily adjust the trip torque by simply turning the adjustment nut. - Compact & Precise (TGB08–16) Ideal for small motors, robots, and compact precision machinery. - Non-Backlash (TGB08–16) Equipped with a non-backlash feature, making it suitable for environments where play is not acceptable. *However, the coupling type has backlash in the coupling section.*

Applications/Examples of results
【Packaging Machine】 It is also used for overload protection of the cutter drive unit in packaging machines. It plays a role in preventing machine failure by idling when foreign objects get caught. It is also used for other applications, so please feel free to contact us regarding the intended use.
Detailed information
-
Application Example 1: Industrial Machinery TGB is installed in the drive section of industrial machinery. It is used to protect the equipment from overload caused by chain jamming and weight from loads.
-
Application Example 2: Packaging Machinery A TGB is installed in the drive unit of the packaging machine. It is used to protect the device from overload caused by foreign objects caught in the cutter section.
-
Application Example 3: Conveyor It is used in the drive unit of the conveyor. It is used to protect the motor, machinery, and transported items from chain entrapment and overload due to weight.
-
Application Example 4: Water Gate When the gate reaches the bottom during descent, a mechanism stops the motor using a limit switch. This is a mechanism to prevent the rack from compressing and buckling in the event of a limit switch failure.
