RLK 404 series

Product catalog summary

Overview: The document provides technical specifications and details for Cone Clamping Elements RLK 404, which are used to center hubs to shafts and transmit high torques without axial displacement during the clamping process.

Features:

Centers the hub to the shaft.
High transmissible torques ranging from 7,000 Nm to 1,206,000 Nm.
No axial displacement between hub and shaft during clamping.
Suitable for shaft diameters between 70 mm and 600 mm.

Application Example: The RLK 404 is used for backlash-free attachment of a belt drum to a conveyor belt drive shaft, maintaining the axial position during clamping.

Simultaneous Transmission: The document notes that when torque and axial force are transmitted simultaneously, both are reduced. Technical details are provided on pages 72 and 73.

Ordering Example: For a shaft diameter of 100 mm, the order would be RLK 404, size 100 x 145, with article number 4205-100401-000000.

Surface and Material Requirements:

Average surface roughness Rz = 10 to 25 µm.
Materials should have an E-module ≥ 170 kN/mm².

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

Tolerances:

h8 for shaft diameter d.
H8 for hub bore D.

Technical Data: The document includes a detailed table of dimensions, technical data, and article numbers for various sizes of the RLK 404, specifying parameters such as yield strength, transmissible torque or axial force, contact pressure, clamping screws, and weight.
