RLK 110 K series

Product catalog summary

Overview: The document provides technical specifications and details for the Cone Clamping Elements RLK 110 K, which are used to center the hub to the shaft and are corrosion protected.

Features:

Centers the shaft to the hub.
All parts are 35 µm chemically nickel-coated for high corrosion resistance according to DIN 50021 (neutral salt spray test).
Capable of transmitting high torques.
Radial flat height is suitable for small hub outer diameters.
No axial displacement between hub and shaft during clamping due to a fixed backstop point.
Transmissible torque ranges from 190 Nm to 2,800 Nm.
Suitable for shaft diameters between 19 mm and 60 mm.

Application Example: The RLK 110 K is used for backlash-free connection of an eccentric wheel to the drive shaft of a packaging machine, with motion transmitted via a driving rod protected by a RINGSPANN force limiter.

Simultaneous Transmission: The document notes that the transmissible torques and axial forces are reduced when both are transmitted simultaneously. Technical details are provided on pages 72 and 73.

Ordering Example: For a shaft diameter of 50 mm, the order would be RLK 110 K, size 50 x 65, with article number 4206-050001-A08101.

Surface and Material Requirements:

Average surface roughness at contact surfaces: Rz = 10 … 25 µm.
Materials for shaft and hub should have an E-module ≥ 170 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.

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 110 K, specifying yield strength, transmissible torque or axial force, contact pressure, clamping screws, and weight.
