Shrink Discs RLK 603 K

Product catalog summary

Specifications:
The document details the specifications for Shrink Discs RLK 603 K, which are corrosion-resistant and made of stainless steel. They are designed for high torque capacity, with transmissible torque ranging from 170 Nm to 23,000 Nm. The discs are suitable for hollow shafts or hubs with outer diameters from 24 mm to 175 mm. All components are rust-free, and the screws conform to DIN 931/933 grade A2-70 standards, lubricated with H1-registered grease.

Features:
The Shrink Discs offer easy disassembly without jacking screws and ensure a backlash-free connection. They are adjustable in the direction of rotation and allow for simultaneous transmission of torque and axial force, although the transmissible values are reduced when both are applied simultaneously.

Application Example:
An example provided is the use of the Shrink Disc in a screening system for bakery products, where it connects a stirring hook to a gear drive, allowing for regular cleaning with fluids due to its stainless steel construction.

Technical Data:
The document includes tables with dimensions, transmissible torque or axial force, clamping screw specifications, and weights for various sizes of Shrink Discs. It also provides formula symbols and calculations for reduced torque and axial force when both are transmitted simultaneously.

Installation and Material Requirements:
Installation instructions are available upon request. The document specifies material requirements, including a yield strength of Re ≥ 300 N/mm² and an E-module of approximately 200 kN/mm². Surface roughness at contact points should be Rz = 10…25 µm.

Tolerances and Joint Clearance:
The transmissible torques and axial forces are subject to tolerances, surface characteristics, and material requirements. Joint clearance between the shaft and hollow shaft must remain within specified ranges to avoid damage and ensure proper torque transmission.

Technical Points:
The axial width of the contact surface should be limited to LF ≤ 1.1 · L1 to prevent harmful fretting corrosion. The friction value assumed is µ=0.15 for dry and degreased steel/steel pairings. Deviations in joint clearance can affect transmissible torque and axial force, and users are advised to contact the manufacturer for specific calculations.
