EMER- FLEX COUPLING

In order to make the EMER-FLEX COUPLING the ultimate disk coupling, Tsubaki optimized its design using finite element analysis. This coupling will meet all of your needs with no lubrication, no backlash, and with improved torsional stiffness for greater precision. This adds up to excellent flexible coupling performance for reliable torque transmission and absorption of shaft misalignment. Tsubaki offers a full line-up of EMER-FLEX couplings, from the smallsize precision NES Series offering a minimum of 0.7N·m torque transmission to the large size NEH Series delivering up to 176000N·m torque transmission. Our easy-to-select and convenient wide range of models include the Long Spacer Type, which functions as a floating shaft; the U-Type that enables spacer mounting and dismounting without disassembling the disk connecting section; the GType, which can replace gear couplings and other types that use various shaft coupling methods (Power-Lock, keyway, clamp, etc.) These EMER-FLEX couplings are ready to meet all of your next-generation coupling needs.

DIMENSI

Extended-Diameter Hubs If the target shaft diameter exceeds the maximum shaft bore diameter of the standard hub regardless of there being sufficient leeway in the Transmission capacity, you may select the extended-diameter hub that provides a larger boss diameter (dimension “H”). This way you can avoid increasing the model size. Long Hubs If the key surface pressure is too high with the standard hub, you may select the long hub that provides a longer dimension “B”, which lowers the key surface pressure. Square Hubs The square hub is used as a combination with the EL Series Power-Lock Type coupling and the pressure flange set. The pressure bolt tap has been machined into the hub.

TRANSMISION CAPACITY

High torsional stiffness_ The high torsional stiffness enables the couplings to provide excellent trackability for servo motors, making the NES Series perfect for precision control applications.

Compact & low moment of inertia_ NES Series couplings employ extra super duralumin in the hub and the spacer, resulting in a compact body. With the reduced outer diameter, this type also lowers the moment of inertia.

RoHS compliant_ The NES Series offers environmentally conscious designs that comply with the RoHS Directive.

Shipment of fully assembled parts _ NES Series couplings are shipped as a complete assembly (with finished bores), so the coupling can be directly mounted to your equipment.

PEMILIHAN PRODUK

1. Correct torque calculation

•

. When connecting to a servo motor or stepping motor 

To determine the correct torque, multiply the maximum torque of the servo motor or stepping motor by the service factor (SF). •

When connecting to a general­purpose motor

To determine the correct torque, multiply the load torque calculated with the following formula by the service factor (SF) . •

Shaft Diameter

- Make sure that the target shaft diameter does not exceed the allowable mounting shaft diameter for the coupling. - With the Power-Lock, check the power lock size, quantity and transmission torque.

12

ABDUL EZREEN BIN ABDULLAH SANI

- With the clamp type, make sure that the correct torque determined in Item (1) does not exceed the allowable transmission torque for the clamp.

•

Maximum Rotation Speed for Long Spacer Types

When using the Long Spacer Type coupling at a high speed rotation, the rotation speed must be checked in order to avoid the resonance point. When selecting the Long Spacer Type coupling, make sure that the maximum dimension “J” and the rotation speed for each model are not exceeded. If the operating rotation speed exceeds the specified value, a larger model number must be selected. If the operating rotation speed is not within the following range, or if the selection of a larger model number is not an option, a “High-Speed Type Long Spacer” coupling can be manufactured as one solution.
