Overview

This document provides comprehensive technical specifications, dimensional data, mounting instructions, and operational parameters for a range of indexing drives (models 25Do, 30Do, 35Do, 45Do, 55Do, 65Do, and 80Do) equipped optionally with spur gear reducers (R48, R65, R80, R100, R125, R160). It serves as a detailed reference for selecting, mounting, and operating these precision indexing drives.

1. General Specifications and Precautions

• Each indexing drive model supports specific reducer types: 25Do and 30Do with R48 and R65; 35Do with R65 and R80; 45Do with R80; 55Do with R80 and R100; 65Do with R100 and R125; 80Do with R125 and R160.
• Reducers can be mounted in up to 16 different positions, requiring careful selection of spacer thickness based on dimension diagrams to ensure proper assembly.
• Standard models ordered with spur gear reducers are considered special specifications and should be confirmed before ordering.
• Oil plug, oil level, and drain locations vary by mounting position and model, with oil capacities specified accordingly.
• Oil levels indicated are general guidelines and must be verified according to actual cam profiles and number of cam followers to maintain proper lubrication.

2. Dimensional Data and Mounting Details

• Detailed dimension figures are provided for each model, including mounting hole locations, bolt sizes, thread pitches, pitch circle diameters (P.C.D.), and surface thicknesses.
• Mounting hole specifications cover index, stationary, and V surfaces with precise measurements to ensure correct installation.
• Mounting positions are illustrated with clear indications of oil plug, oil level, and drain points for proper oil management.

3. Spur Gear Specifications

Note: Pinion shaft speed should be maintained below 30 rpm to ensure allowable torque and bending force limits are not exceeded.

4. Performance Parameters

• Output allowable axial and radial loads, static torque, torsional rigidity, and bending moments are specified per model.
• Input allowable axial load, maximum repetitious bending force, maximum repetitious allowable torque, and input torsional rigidity are provided.
• Indexing accuracy is detailed for 1 to 4 dwell positions, with typical angular deviations ranging from ±20 to ±120 seconds depending on model and dwell count.
• Product weights increase with model size, ranging from approximately 20-30 kg (smaller models) up to 780 kg (largest models).
• Housing color is consistently gray across all models.

5. Mounting and Oil Management

• Mounting positions correspond to specific codes for indexing, oscillating, and roller drives.
• Oil plug and drain ports use PT1/2 or PT3/4 threads depending on model size.
• Oil capacity varies by model and mounting position, with specific volumes indicated in mounting diagrams.
• Oil level indicators (VA or VA-01) are positioned according to mounting orientation and cam profile to ensure proper lubrication.

6. Model Coding Examples

• Model codes include indexing drive designation, reducer type, and spur gear reducer model (e.g., 1SRG3VW16242R25DO for 25Do with spur gear reducer SG25).
• Reducer codes such as R48, R65, R80, R100, R125, and R160 specify the reducer type used.

7. Critical Notes and Recommendations

• Careful selection of spacer thickness based on dimension diagrams is essential for correct reducer mounting.
• Standard models with spur gear reducers are special order; confirm specifications before procurement.
• Oil levels must be verified according to actual cam profile and follower count to maintain proper lubrication and performance.
• Input inertia (J) is calculated during dwell periods and is critical for dynamic performance assessment.
• Pinion shaft speed should be kept below 30 rpm to avoid exceeding allowable torque and bending force limits.

8. Summary of Critical Parameters for 65Do and 80Do Models

Note: Values are approximate and should be confirmed with detailed tables and drawings for design and application.

Conclusion

This document is an essential technical guide for engineers and technicians involved in the selection, installation, and maintenance of indexing drives with spur gear reducers. It ensures optimal performance, reliability, and longevity by providing precise mechanical dimensions, load capacities, inertia values, lubrication guidelines, and critical operational limits.
