Description

Technical Field

[0001] The utility model relates to the technical field of dynamic balance correction devices for customized bearings, and specifically provides a dynamic balance correction device for customized bearings. Background Art

[0002] Dynamic balance correction is a process used to ensure minimal vibration during the operation of rotating mechanical components. For customized bearings, the dynamic balance correction device needs to be able to adapt to bearings of different sizes, shapes, and weights to ensure their stability during high-speed rotation. Many modern balancing machines use automation technology to automatically perform single-sided or double-sided dynamic balance measurements, reducing human error and improving efficiency.

[0003] Before the dynamic balance correction device corrects the dynamic balance of the bearing, the staff first immerses the bearing in a cleaning agent or injects the cleaning agent into the bearing interior using a pressure spray method to remove the residual lubricant. Since the cleaning medium used is water or a solution containing water, water stains may remain on the bearing after cleaning. If the bearing with water stains is subjected to dynamic balance correction, it will affect the positioning of the bearing in the dynamic balance correction device, resulting in inaccurate measurement results.

[0004] Therefore, a dynamic balance correction device for customized bearings is proposed to address the above problems. Content of the Utility Model
