Overview of XB Series Cardan Shafts

The document provides detailed technical specifications and flange characteristics for the XB series of cardan shafts, covering models from XB160 to XB620. It includes transmissible torque values, main dimensions, weights, and flange connection types.

1. Transmissible Torque Values

Four torque parameters are specified for each XB model (in KNm):

• Tn: Nominal torque, ranging from 22 KNm (XB160) to 1335 KNm (XB620).
• Tf: Fatigue torque, ranging from 11 KNm to 667 KNm.
• Tp: Peak torque, ranging from 16 KNm to 967 KNm.
• Tcs: Service torque capacity, ranging from 28 KNm to 1735 KNm.

Additionally, a bearing capacity factor kL is provided, increasing with shaft size, indicating bearing load capacity.

2. Main Dimensions and Weights

Dimensions and weights are given for five types (A, B, C, D, E) of shafts across the XB series:

• Length (L): Varies by type and model, e.g., Type A ranges from 740 mm (XB160) to 2280 mm (XB620).
• Weight (m): Increases with size, e.g., Type A from 65 kg to 2830 kg.
• Other parameters include ALv and Lv for some types, likely related to length variants.

Maximum operating angle (ßmax) is consistently 15° for all sizes.

3. Dimensional Parameters

Key dimensional data for each model include:

• D: Diameter (160 mm to 620 mm).
• D3x∆: Dimension with tolerance, e.g., 114x10 mm for XB160.
• Df, D1, D2: Various flange and shaft diameters with tolerances.
• Lm, t, K, g, b, n: Additional geometric and mechanical parameters such as thickness, key dimensions, and number of holes.

Custom sizes are available on request.

4. Flange Series XB - Types and Descriptions

The document details five flange connection types used in the XB series:

• BHC: Bolt Hole Connection (flange without key).
• IKC - PKC: Partial and Integral Face Key Connections.
• IPC: Partial Face Key Connection.
• HSC: Hirth Serration Connection.

Each flange type is associated with specific standards (e.g., BHC/SP - DIN15452) and dimensional characteristics.

5. Flange Specifications

Detailed flange dimensions are provided for each XB size and flange type, including:

• Diameters (Df, D1, d), thickness (t), keyway dimensions (b, g), number of holes (n), and other geometric parameters.
• Number of teeth (z) and holes (n) for serrated connections.

Angular measurements for teeth and hole spacing are specified (e.g., 22.5°, 45°, 30°, 20°) depending on flange type.

6. Notes and Recommendations

• The manufacturer continuously develops intermediate sizes beyond standard ones to provide a wider range of torque values for precise cardan shaft sizing.
• Different measures and customizations are available upon request.

Critical Information Summary

• Torque capacities must be selected according to application requirements, considering nominal, fatigue, peak, and service torques.
• Dimensions and weights vary significantly across types and sizes; proper selection ensures mechanical compatibility and performance.
• Flange types and specifications are crucial for connection integrity; selection depends on application and standard compliance.
• Maximum operating angle is limited to 15° for all XB series shafts.
• Custom sizes and intermediate dimensions enhance flexibility in design and application.
