Shock Relay Manages Electrical Line Surges to Prevent Damage

 

Shock Relay Overload Protection Device

An unexpected electrical surge or an obstruction on your production line can put unnecessary strain on motors and other drive components, resulting in equipment failure and unscheduled downtime. While shocks and jams are common, and sometimes unavoidable, having the proper overload protection device can help you save on expensive maintenance and repairs.

With the Tsubaki® Electronic Shock Relay, you can detect problems on your production line before they result in costly equipment damage. The system monitors for an increase or decrease in line amperage, and, in the event of a surge, automatically shuts down the line to prevent damage to critical equipment.

 

How Electronic Shock Relay Works

The Shock Relay device is easy to set up, allowing you to get equipment up and running again in no time. The system requires three set-points, or overload parameters, to be established at installation. The first set-point, the amperage limit, determines the maximum amperage that is desired for the motor. The second point, the shock time, determines how long the system can continue operation if amperage exceeds the first set-point before it trips. The last point, the start time, determines how long to allow the motor to pull amperage above the amperage limit during startup.

If an overload is detected, the Shock Relay will shut down the line by sending a shutdown signal to the motor contactor and display an alarm on the Shock Relay. This allows you to safely remove the obstruction from the production line or investigate the cause of the electrical surge. Once the issue has been corrected, you can reset the system automatically or manually at the touch of a button.

Getting Started with Tsubaki Shock Relay

Shock Relays generally work with any voltage AC motor – single or three-phase – and are commonly used in applications involving conveyors or bucket elevators, like those used in the material handling or food processing industries. Shock Relays can also be used with pumps, filters, and other equipment found in water treatment or chemical plants, as well as tapping machines and drill presses relied on by the machine tool industry.

Each Shock Relay device can protect equipment that is up to 1,000 feet away, but it is best practice to have one Shock Relay monitor per motor. Shock Relays are solid state electronics with no wear components and are designed to retain set point accuracy to ensure safe, reliable and efficient operations day after day.

In addition to its Electronic Shock Relay devices, Tsubaki also offers a line of mechanical shock guards for harsh environments where dust, humidity and high temperatures create additional challenges for electronic devices.

Whatever your application needs may be, Tsubaki has the solution you need to safeguard your power equipment and eliminate unscheduled downtime.

Tsubaki KabelSchlepp PROTUM® Office Series Enables Smart Cable Management

 

KabelSchlepp Protum

Cable management is an important consideration for any space that will house technology equipment or systems—including servers, computers, monitors, and more. Control rooms and data centers for powerplants, utility companies, emergency dispatch centers, and other industries providing essential services all need effective cable management solutions to ensure efficient and uninterrupted operation.If cables are not properly organized, they can get tangled and become difficult for a technician to conduct maintenance, troubleshoot and repair. They can also take up valuable desk space and are not visually appealing.  The Tsubaki® Kabelschlepp® PROTUM® Office Series offers a space-saving cable management solution for these environments. The small, light cable carriers can be easily installed at workstations and in control rooms to keep cables organized and protected.

 

Layout allows for proper spacing between cables

With an inner width of 50 mm and the ability to install cables along both sides of the center element, PROTUM Office allows for complete separation of data and power cables. Ensuring the proper separation is important because power cables can create an electromagnetic interference that will slow the speed of data transmission if the two cables are positioned too closely together.

Easy installation saves time

Installing PROTUM Office is quick and easy – simply press the cables into the tracks. PROTUM Office also offers a high degree of customization in terms of how it is positioned to the workstation. End connectors can be fixed underneath table tops or cable ducts, to rectangular or round table legs, or to the floor.

 

Sleek design blends in with office environments

Torque Limiter Sprockets Offer Maximum Protection from Torque Overload

Torque Limiter Sprockets parts

When your equipment and machinery approach torque overload, you’ll be thankful you have a Torque Limiter to protect critical drive components.
Torque Limiters are often used in conjunction with sprockets, which guide the rotational movement of equipment and machinery, and serve as an automatic safeguard against torque overload. They are usually sold separately, but U.S. Tsubaki now offers user-friendly, cost-effective Torque Limiter Sprockets, which come pre-assembled and can be made in various sizes and tooth counts for any application.

How does the Torque Limiter Sprocket work?

The Torque Limiter Sprocket works by transmitting torque via two composite friction disks, which are compressed by disk springs against the ground face of the hardened tooth sprocket. The end-user sets the torque limit by tightening the adjusting nut on the device.

During normal operation, when no torque overload is occurring, the Torque Limiter will transmit torque from the driven shaft to the sprocket via the friction disks. As the drive shaft runs, the spring will compress the friction disks against the sprocket. This creates a frictional force that transmits the power from the drive shaft to the sprocket.
When a torque overload occurs, such as during a mechanical jam, the transmitted power will exceed the set torque point, causing slipping between the friction disks and sprocket. If slipping occurs, the frictional force will no longer be strong enough to transmit the torque from the drive shaft to the sprocket. The drive shaft will continue to run, but no torque will be applied to the sprocket. Once the torque overload is removed, the Torque Limiter will automatically reset and resume transmitting torque.

Applications and Uses for Torque Limiter Sprockets

Torque Limiter Sprockets can be used for a variety of applications where continual movement of the machine is important, including conveyors, gearboxes and motors. The slipping of the friction disks allows the machine to power through temporary jams and load increases without incurring damage. Without a torque limiting device, critical drive components are at risk of failure or breakage from torque overload.

By combining the Torque Limiter and sprocket into one product, customers now have access to a complete torque limiting solution that can be customized for specific applications and machinery.

U.S. Tsubaki offers a wide selection of mechanical protection devices and Torque Limiters for any application. To learn more about Torque Limiter Sprockets and select the right configurations for your facility, contact us today.

Protect Your Cables from Dirt, Grime and Particulates

 

 

When selecting the proper cable carrier for your application, consider the environment in your plant.  Are your dynamic cables coming into contact with foreign bodies, such as hot chips, chemicals, or other contaminants that might cause damage to the cables? If so, they might need extra protection.  For example, a machine tool that cuts material such as metal or glass will create shavings, chips, and other particulates that can fall on the cable track. Once inside the cable carrier, these particles will cause wear and tear on the cables and hoses as they move. This could lead to severe cutting and damaging of the cables over time, which may result in cable failure, contribute to downtime, and ultimately, lost revenue.

Selecting the right enclosed cable carrier

 

Enclosed plastic and hybrid cable carriers offer an additional layer of protection, ensuring that debris cannot enter the carrier. These are ideal for applications where coarse contamination, such as chips, metal parts, glass splinters or hot metal spatter, is likely. In many cases, enclosed cable carriers are also used to hide the cables for aesthetic reasons.

The IP Enclosure Rating indicates the level of protection a cable carrier provides against outside contaminants and can help you select the right cable carrier solution for your needs.

 

Ensuring maximum protection with the KabelSchlepp® TKA Series

The industry’s highest-rated enclosed cable track is the KabelSchlepp TKA series, which is ideal for environments where machine cutting equipment is manufactured or used. It has an IP54 rating, which means the enclosed cable track will not allow anything down to a dust particle or liquid splash to enter the carrier. This level of protection will help ensure maximum life for your cables and hoses.

The TKA enclosed cable track can be made with a variety of material types for custom applications, including custom molded materials to protect against hot chips up to 850 °C. In addition to the high level of protection it offers, the TKA series cable track uses easy-open lids for installation and inspection – offering access to the cables at any link of the cable track – and operates quietly.
