Help with Balancing Machines and Systems specifications:
Configuration
Back to Top
|
| ||
| Configuration | |||
| Your choices are... | |||
| Horizontal | Horizontal balancing machines have clamps or rotor supports along a horizontal plane. The object under test is rotated about this axis. | ||
| Vertical | Vertical balancing machines have clamps or rotor supports along a vertical plane. The object under test is rotated about this axis. | ||
| Cradle / Wrap-Around | Cradle or wrap-around balancers are conventional machines that can be used to test large and/or heavy parts when support is needed on both ends of the part under test. | ||
| Overhung / Side Loading | Overhung or side-loading balancing machine and systems are cantilevered and allow for quick part-changes. | ||
| Modular System | Modular systems have a central interface and several sensors or components which must be mounted to the part under test. | ||
| Other | Other unlisted, specialized, or proprietary balancing machines or systems. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| |||
| Rotating | Rotating balancing machines and systems use the dynamic behavior of the spinning part or object to achieve balance. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
| |||
| Non-Rotating | Non-rotational balancing machines and systems run diagnostics by suspending the part, observing the center of gravity, and identifying any tilt or misalignment. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||

Measurements / Test Modes

|
| ||
| Measurements / Test Modes | |||
| Your choices are... | |||
| Dynamic (Two-Plane) | Dynamic balancing machines run diagnostics and offer the ability to perform two-plane balancing, for both couple and force unbalance. | ||
| Static (Single-Plane) | Static balancing machines run diagnostics on the balance of an object about a single axis. Force unbalance can be detected and corrected for. | ||
| Couple Measurement | Couple unbalance is a condition where the inertia axis is not parallel with the axis of rotation. Couple unbalance can only be detected by rotational analysis. | ||
| Force Measurement | Force unbalance is a condition where the center of balance is not located on the axis of rotation and can be detected by non-rotational balancing machines and systems. | ||
| Moment Weighing | Moment weighing is performed on blades or rotor components, and helps locate the optimal location during component fabrication. | ||
| Spin / Burst Tests | Spin tests help analyze the effects of centrifugal force on the part under test. Accelerating a product to its burst point is a destructive testing method used for research and development. | ||
| Vibration Analysis | The instrument or system can be used for vibration analysis. | ||
| Other | Other unlisted, specialized, or proprietary measurements or test modes. | ||

| Features | |||
| Your choices are... | |||
| Belt Drive | The test fixture or spindle is driven by a motor coupled by a belt and pulley. | ||

| Hard Bearing | Balancing machines use a hard-bearing suspension system. Transducers directly measure unbalance or centrifugal force. Because the bearing fixtures are stationary, the measurement system is not dependent upon rotor mass. This can eliminate or reduce the need to recalibrate balancers for different parts, as is sometimes the case with soft-bearing systems. | ||
| Integral Software | Balancing machine or system has integral software that is used to run tests or help balance the part. | ||
| On Machine Correction | Balancing machine or system contains an integral drill or correction unit used to machine the test piece and correct the unbalance. | ||
