RLK 606 series

Product catalog summary

Shrink Discs RLK 606 Overview

Design and Features:
The RLK 606 is a two-part shrink disc designed for high torque capacity. It offers a transmissible torque range from 165 Nm to 36,200 Nm. The assembly is straightforward and quick, requiring only the tightening of clamping screws without a torque wrench. The design ensures a dirt-resistant enclosure and maintains true running even at high speeds. It is suitable for hollow shafts or hubs with outer diameters ranging from 24 mm to 155 mm.

Application Example:
The RLK 606 can be used for backlash-free connections, such as connecting a bevel spur gear to a gearbox drive shaft, allowing for extended reversing operations.

Simultaneous Transmission:
The transmissible torques and axial forces are specified for cases where either torque or axial force is zero. When both are transmitted simultaneously, their values are reduced. Further technical details are available on page 31.

Ordering Information:
An example order for a hollow shaft with an outer diameter of 100 mm would be RLK 606-100, with article number 4200-100601-000000.

Surface and Material Requirements:
The average surface roughness at contact surfaces should be Rz = 10 to 25 µm. The shaft and hollow shaft should have a yield strength of at least 360 N/mm² and an E-module of approximately 206 kN/mm².

Installation:
Installation and operating instructions are available upon request. The transmissible torques or axial forces are subject to specific tolerances, surface characteristics, and material requirements.

Technical Data and Dimensions:
The document provides detailed tables with dimensions, technical data, and article numbers for various sizes of shrink discs. These include specifications for transmissible torque or axial force, clamping screws, and weight.

Note:
The shaft diameters listed are examples, and other diameters can be found in the technical specifications on page 31.
