Variable Speed Brush Device for Wheel Front Face Burr Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for burring the front face of a wheel, particularly at the central riser part, suffer from low linear speed which inadequately addresses burr removal, affecting subsequent coating processes.
Innovation Solution
A device comprising a rack, support plate, gear racks, brushes, and motors allows for different rotation speeds of the central and spoke brushes to effectively burr the wheel's front face, with a central brush rotating at high speed and outer ring brush at slower speed, enabling efficient burr removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a big disc brush is used to directly burr the front face at constant angular speed, then the device structure is simple, but the linear speed at the central part is relatively low which fails to effectively remove burrs
Solution Approach 1:
The single disc brush is segmented into multiple brush components: a central brush for the hub center and spoke roots, and outer ring brushes for the rim area. Each brush can be independently controlled to provide optimal linear speed for its specific region, resolving the speed uniformity issue while maintaining manageable device complexity through modular design
Solution Approach 2:
The patent implements independent speed control for different brush components through a variable speed motor system. The central brush and outer ring brushes can rotate at different angular speeds, allowing dynamic adjustment of linear speed at each position to effectively remove burrs throughout the entire front face
2Manufacturing precision
If a big disc brush rotates at constant angular speed, then the control system is simple, but the burring effect at the central part is poor due to low linear speed
Solution Approach 1:
The control system is enhanced with variable speed motors that allow independent adjustment of rotation speeds for different brush components. This dynamic control enables optimal linear speed at each position (high speed at center, lower speed at outer regions), significantly improving burring precision while the modular control architecture keeps system complexity manageable
Solution Approach 2:
Different regions of the front face receive customized burring treatment through locally optimized brush speeds. The central brush operates at higher speed for effective burr removal at the hub center and spoke roots, while outer ring brushes operate at lower speeds appropriate for the rim area, achieving uniform high-quality burring across all regions

AI summary
The present invention relates to a device for burring a front face of a wheel. The device is composed of a rack, a motor, a guide rail, air cylinders, brushes and the like. A sensor enables the wheel to be positioned on a roller way, a clamping air cylinder drives left rolls and right rolls via synchronous gears and gear racks to clamp the wheel, a servo motor drives the wheel to rotate at relatively low speed under the clamped condition, and the rotation direction of the wheel is opposite to that of the brushes; the air cylinders I enable a dust cover to go down, and the motor drives a gear I and a central brush via a shaft II to rotate at relatively high speed; the gear I drives a gear II and a gear III to rotate simultaneously at slightly slow speed, so as to drive an outer ring brush to also rotate at relatively slow speed; and the air cylinders II drive the central brush and outer ring brush to go down, and burring can be performed once the central brush and outer ring brush contact the front face of the wheel. When in use, the device provided by the present invention can burr the central part and the spoke of the wheel at different rotation speeds, and the problem that the traditional big disc brush has low linear speed at the central position when rotating at fixed angular speed is avoided.
