Dimensions and Mounting Information
- Refer to the dimensional drawing for the overall dimensions, mounting holes, and interface details of the 90YH. Check the available installation space and mounting arrangement before integrating the rotary table into the machine.
- The mounting interface, load conditions, and drive requirements should be reviewed together when selecting the unit for a specific application.
Typical Applications
The 90YH can be used in automated machinery that requires rotary indexing and repeatable positioning under load.
- Heavy-duty indexing stations that require controlled rotary movement while supporting workpiece loads.
- Multi-station assembly systems that position workpieces at successive assembly or processing stations.
- Automated inspection equipment that rotates workpieces for inspection or measurement.
- Industrial automation machinery that requires a hollow rotary structure and defined indexing accuracy.
Suitability depends on the workpiece load, center of gravity, rotational inertia, operating speed, and duty cycle. These conditions should be checked during model selection.
Drive Configuration and Customization
The 90YH uses a planetary gearbox and servo motor. The drive configuration should be selected according to the motion requirements and installation conditions of the equipment.
The following information helps determine whether the standard configuration is suitable:
- The required indexing angle, positioning accuracy, and machine cycle time.
- Workpiece weight, center of gravity, radial load, axial load, and rotational inertia.
- Required input speed, operating frequency, and duty cycle.
- Available mounting space, interface dimensions, and motor arrangement.
- Servo motor specifications and compatibility with the machine's motion control system.
For applications with specific installation or operating requirements, provide the machine layout, mounting drawings, and relevant operating parameters for technical evaluation. The configuration and customization options can then be assessed against the actual application.
FAQ
Q: What is the allowable thrust load of the 90YH rotary table?
A: The specified allowable thrust load is 350 kgf. This is a force rating and should not be treated as the maximum permissible workpiece mass for every operating condition. Load direction, center of gravity, rotational inertia, and operating conditions must also be considered.
Q: What drive system does the 90YH use?
A: The 90YH uses a planetary gearbox and servo motor, with a reduction ratio of 20:1. The maximum input speed is specified as less than 1,000 r/min. The operating speed and motion settings should be determined according to the machine's requirements and the applicable operating limits.
Q: What are the positioning accuracy specifications of the 90YH?
A: The repeat positioning accuracy is ±5 arcsec, and the indexing accuracy is ±20 arcsec. These are separate specifications and should be considered according to the positioning requirements of the application. Actual performance in the installed machine also depends on the mounting arrangement, load conditions, and operating setup.
Q: Can the 90YH be customized for a specific machine?
A: Application-specific requirements can be submitted for technical evaluation. Relevant information includes the required indexing angle, workpiece load, center of gravity, operating speed, installation dimensions, and machine drawings. The proposed configuration can then be assessed for compatibility with the intended application.
