Additive Manufacturing Counterweight for Scroll Compressor

The patent applies parameter changes by varying the infill density (material distribution) within a standardized counterweight geometry. By adjusting the infill percentage and pattern in different regions of the counterweight, the mass and center-of-gravity can be precisely controlled to match different compressor model requirements, while the external dimensions and mounting features remain constant, allowing universal tooling and handling equipment to be used across all models.

The patent implements universality by designing a standardized counterweight outer geometry that can serve multiple compressor models. The universal mounting portion with consistent dimensions and attachment features allows the same counterweight design to be used across different models, while the internal infill structure is customized through additive manufacturing parameters to achieve model-specific mass and balance characteristics, eliminating the need for model-specific tools and handling equipment.

The patent replaces traditional mechanical machining processes with additive manufacturing technology. Instead of machining counterweights from solid material to achieve precise mass and center-of-gravity, the invention uses 3D printing to directly create the counterweight with optimized infill structures. This substitution of manufacturing methodology enables precise mass adaptation while significantly reducing production costs by eliminating expensive machining operations and material waste.

The patent uses parameter changes in the additive manufacturing process, specifically varying the infill density and pattern parameters, to achieve precise mass adaptation. By controlling the infill percentage (e.g., 10-100%) and pattern type in different regions of the counterweight during the printing process, the exact mass and center-of-gravity position can be achieved without any post-manufacturing machining, thereby reducing production costs while maintaining high precision.

The patent applies parameter changes by maintaining a standardized counterweight outer geometry and instead optimizing the internal infill parameters (density, pattern, distribution) to achieve the required mass and balance characteristics. This approach allows mass optimization for different compressor models without changing the external dimensions or shape of the counterweight, thereby eliminating the need for design changes in the compressor housing.

The patent implements universality by designing a standardized counterweight geometry that fits all compressor models in the product line. The universal external dimensions and mounting features allow the same counterweight shape to be used across different models, while the internal infill structure is customized through additive manufacturing to achieve model-specific mass optimization, thereby eliminating the need for housing design changes.
