DT, DTR series
Overview
This document provides comprehensive technical specifications, mounting instructions, and accessory details for a range of indexing and rotary drive models, including smaller series (8DT to 35RT) and larger models (45DT to 80DTR). It covers reducers, torque limiters, mounting positions, oil management, mechanical and performance parameters, and installation guidelines.
1. Models and Accessories
- Models Covered: 8DT/8RT, 11DT/11RT, 14DT/14RT, 18DT/18RT, 25DT/25RT, 35DT/35RT, 45DT/45DTR, 55DTR, 65DTR, 80DTR.
- Reducers: Various reducers such as R48, R65, R80, R100, R125, and R160 are compatible depending on model size.
- Torque Limiters: Available for each series (e.g., 8To, 11To, 14To, 20To, 25To).
2. Mounting and Installation Precautions
- Reducers can be mounted in multiple positions (up to 16 for smaller models), each with specific codes for indexing, oscillating, and rotary drives.
- Mounting positions define locations for oil plugs, oil levels, and drain ports, with plug sizes ranging from PT3/8 to PT3/4 or PT1/PT2 for larger models.
- Oil levels depend on cam profile and number of cam followers; general guidelines are provided.
- Some models require collars for mounting (e.g., 14DT/14RT).
- Correct mounting orientation is critical to ensure proper lubrication and oil level maintenance.
3. Dimensions and Mechanical Specifications
- Detailed dimensional drawings specify mounting hole patterns, pitch circle diameters (P.C.D), grease nipple locations, and indexing reference points.
- Input/output shaft dimensions, tolerances, and keyway details are included for precise installation.
4. Performance Specifications
- Key parameters include output allowable axial and radial loads, static torque, torsional rigidity, bending moments, input allowable axial loads, and maximum repetitive bending forces.
- Indexing accuracy varies by model and dwell count, ranging from ±20 to ±120 seconds.
- Repetitive accuracy and product weights are specified for each model.
- Input and output shaft inertia values are provided for dynamic performance calculations.
5. Oil Capacity and Lubrication
- Oil capacities vary by model and mounting position, from approximately 0.8 liters (small models) up to 40-50 liters (largest models).
- Oil plugs, oil level indicators, and drain points are clearly marked for maintenance.
- Grease nipples are positioned for regular lubrication.
6. Color and Material
- All housings are painted gray.
7. Example Model Codes
- Model codes for indexing drives, reducers, and torque limiters are provided to assist with ordering and identification.
8. Large Model Series (45DT to 80DTR) Specifics
- Mounting positions correspond to specific oil plug and level locations (PT1/PT2 plugs, VB/VC oil levels).
- Oil levels depend on cam profile and follower count; detailed tables and figures illustrate capacities and positions.
- Mechanical specs include output static torque, torsional rigidity, bending moments, input/output allowable loads, and indexing accuracy.
- Product weights range from ~1500 kg (45DT) to 12,000 kg (80DTR).
- Indexing accuracy ranges from ±20 to ±80 seconds depending on model and dwell count.
9. Critical Parameters Summary Table
| Model | Output Static Torque (N·m) | Product Weight (kg) | Indexing Accuracy (sec) | Output Allowable Axial Load (N) | Output Allowable Radial Load (N) |
|---|---|---|---|---|---|
| 45DT / 45DTR | ~3.14×107 | 1500 - 1800 | ±20 to ±80 | ~45080 | ~12740 |
| 55DTR | ~4.41×107 | 4000 | ±20 to ±80 | ~48020 | ~13720 |
| 65DTR | ~9.02×107 | 6500 | ±20 to ±80 | ~57820 | ~14700 |
| 80DTR | ~4.12×108 | 12000 | ±20 to ±80 | ~62720 | ~38220 |
10. Precautions and Recommendations
- Verify correct mounting position to ensure proper alignment of oil plugs, levels, and drains.
- Adjust oil levels based on cam profile and follower count for optimal lubrication.
- Confirm reducer compatibility and mounting codes before installation.
- Perform regular maintenance including lubrication via grease nipples.
- Consult torque capacity tables to ensure application loads are within limits.
11. Conclusion
This document is a detailed technical reference for selecting, installing, and maintaining indexing and rotary drives across multiple model ranges. It highlights the importance of precise mounting, lubrication management, and adherence to mechanical and performance specifications to guarantee reliable, accurate, and long-lasting operation.
