Product catalog summary

Technical Specifications:
The document provides detailed specifications for brake discs optimized for use with RINGSPANN brakes. The brake discs are made from EN 1563 EN-GJS500-7 material, suitable for high heat absorption. Available diameters range from 125 mm to 1000 mm, with thickness options of 12.5 mm and 25 mm. The discs can be ordered with different bore configurations, including pre-drilled, finished bore with or without keyway, and shrink disc options.

Performance Parameters:
The document includes a table listing various parameters such as maximum speed, inertia moments, and maximum braking torque for different disc sizes. The maximum speed ranges from 1,800 min-1 to 14,500 min-1, and the maximum braking torque reaches up to 3,480,000 Nm for the largest disc size.

Design and Installation:
Brake discs are available in different forms (B, F, S) and are designed for easy installation. The document provides guidelines for dimensioning and surface roughness, emphasizing the importance of maintaining an average surface roughness of Ra ≤ 3.2 µm at contact surfaces.

Heat Absorption and Dissipation:
The document outlines the permissible braking actions and heat absorption capabilities of the brake discs. It specifies that the maximum disc temperature should not exceed 300°C, with ambient temperatures at 20°C. For high-frequency braking (z > 40 per hour), detailed information on speed and braking torque is required for design verification.

Braking Calculations:
Formulas are provided for calculating reduced inertia moment, required braking torque, brake power, and braking energy. The document emphasizes ensuring that the braking energy capacity of the disc (WBSzul) is greater than the absorbed energy (WB) to prevent overheating.

Recommendations:
For extreme braking processes, it is recommended to verify that the brake disc does not exceed 300°C and that braking time does not exceed 10 seconds. Additional calculations are advised for indexing operations to ensure safe operation.

RINGSRANN Verification of Heat Absorption Permissible Braking Action with Single Braking Operation Extreme braking processes should be checked to ensure that the brake disc will not reach 300° C when absorbing the braking energy. The braking time in this case should not exceed 10 seconds. As an example, you can see in the table the braking energy a brake disc can absorb together with a brake size 020/025/030 without exceeding 300° C. We recommend that this additional calculation be carried out in the case of indexing operations. The absorbed energy Ensure that: for the deceleration of rotating...
