Product catalog summary

Introduction
The document introduces the Sandex (Alpha) series, a new environmentally friendly and efficient addition to the Sandex series of indexing drives by Sankyo, aligning with ISO14000 standards. It aims to enhance productivity while maintaining conservation efforts.

Description
The Sandex series features a low-profile indexing drive with a cost-effective geared motor and a standard frequency inverter, eliminating the need for clutch/brake components, thus reducing maintenance and costs. It is designed for easy integration with a rigid output surface for direct mounting of dials.

Features

Eight standard sizes with center distances from 70mm to 450mm.
Wide selection of stops from 2 to 32.
Rigid large flange surface and low-profile housing.
Standard hollow fixed shaft inside the output flange.
Mountable with up to 3 pairs of timing cams and sensors.
Optional torque limiters for the output shaft.
Standard hollow-center shaft-type geared motor with inverter controller.

Specifications
Detailed specifications for models (7AD, 9AD, 11AD, etc.) include dimensions, torque capacity, and motor power options. Tables for torque capacity and sizing, as well as model selection data, are provided.

Model Code and Options
Model codes are specified by a combination of numbers and alphabetic characters, indicating size, motion curve, hand of cam, and other specifications. Optional features include torque limiters and inverters.

Precautions and Handling
Precautions for mounting positions, oil capacities, and the importance of specifying correct product codes to ensure compatibility and functionality are outlined.

Conclusion
The Sandex Alpha series offers a robust solution for industrial automation, combining ecological and economical benefits with advanced motion characteristics and ease of maintenance.

Model Specifications
Model 9AD: Available with 0.2kW and 0.4kW motors, compatible with torque limiter 9TAD, supports up to 3 sets of timing cams and photo switches.
Model 11AD: Available with 0.4kW and 0.75kW motors, compatible with torque limiter 11TAD, supports up to 3 sets of timing cams and photo switches.
Model 15AD: Available with 0.75kW and 1.5kW motors, with a special option for a 2.2kW motor, compatible with torque limiter 15TAD.
Model 19AD: Available with 1.5kW and 2.2kW motors, compatible with torque limiter 19TAD.

General Precautions

Specific mounting positions and oil capacities vary based on the cam profile and number of cam followers.
Dimensions and mounting positions are provided for each model, with notes on motor protrusion and compatibility.

Torque Capacity and Procedures
Torque transmission capacity is consistent regardless of the cam's rotating direction. Tables are divided based on cam curve codes and dwell types, providing detailed torque values for different input shaft speeds and indexing periods.

Recommendations
Proper mounting and lubrication are critical for achieving expected service life and performance of the cams.

Specifications and Procedures
Includes torque calculations, model selection, cam shaft torque calculations, motor selection, backlash factor calculations, lifetime check, and geared motor selection.

Handling and Installation
Ensure clean mounting surfaces, maintain ambient temperature, test run machines manually, and ensure proper lubrication.

Variable Frequency Drive (VFD) Sizing
Determine efficiency and calculate VFD capacity for continuous and start/stop operations, including inertia calculations and braking time.

Torque Limiter Specifications
Details on tripping torque, thread pitch, and allowable loads for various models, with graphs showing the relationship between spring deflection and trip torque.

Oil Viscosities
Recommendations for oil types and viscosities based on input shaft speed and operating conditions.

Specifications and Maintenance

Use high-quality mineral oil with pressure additives, ensuring not to mix oils from different manufacturers.
Regular maintenance is crucial as backlash increases over time.
Ensure the indexer is not overfilled with oil to prevent temperature rises and leaks.

Lubrication of Geared Motors

Motors ranging from 0.1 kW to 1.5 kW and 2.2 kW are lubricated by grease, which typically does not require replacement.
For larger motors, replace the oil every 10,000 hours or once every two years.

Technical Specifications

Mounting bolts and tightening torque specifications are provided for various models.
Details on index dial application, geared motor, and conveyor application are outlined.

Contact Information

Contact details for Sankyo Seisakusho Co. and its global branches are provided for further inquiries and support.

Model Selection information Sandex model codes are specified by a combination of numbers and alphabetic characters. An erroneously specified product code will usually result in a product unusable in other applications. Use the same caution when specifying the product code for the geared motor and optional torque limiters. When specifying other requirements such as special gear ratios, motor voltages, copper plated terminal boxes, etc., include the symbol X at the end of the product code and attach a separate user requirements sheet. Queries concerning price, volume, and delivery should be directed...
