Cone Clamping Elements RLK 402 RINGSPANN

Product catalog summary

Overview: The document provides technical specifications and application details for Cone Clamping Elements RLK 402, which are used to center the hub to the shaft and transmit high torques without axial displacement.

Features:

Centers the hub to the shaft.
Capable of transmitting the highest torques, suitable for heavy-duty applications.
No axial displacement between hub and shaft during clamping.
Transmissible torque ranges from 840 Nm to 414,500 Nm.
Compatible with shaft diameters between 25 mm and 300 mm.

Application Example: The RLK 402 is used for backlash-free attachment of a belt drum to the drive shaft of a conveyor belt, ensuring no axial shift 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 74 and 75.

Ordering Example: For a shaft diameter of 100 mm, the order would be RLK 402, size 100 x 145, with article number 4205-100201-000000.

Surface and Material Requirements:

Average surface roughness Rz = 10 to 25 µm.
Material 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 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 402, specifying yield strength, transmissible torque or axial force, contact pressure, clamping screws, and weight.
