hjulprofilering

Hjulprofilering is a term originating from Swedish that describes the process of shaping or machining the tread of a wheel, particularly a railway wheel or a tire. The primary goal of wheel profiling is to maintain the optimal shape of the wheel's circumference to ensure safe and efficient operation.

In the context of railway wheels, profiling involves removing material from the wheel tread to correct wear patterns that develop over time due to friction with the rails. This wear can cause the wheel to become flat-spotted, develop a conical shape, or exhibit other irregularities. A properly profiled wheel has a specific profile, often a combination of a cylindrical section and a conical taper, which helps it to guide itself along the track and maintain a stable position. This profile is crucial for reducing rolling resistance, minimizing wear on both the wheel and the rail, and preventing derailments.

For vehicle tires, wheel profiling, often referred to as tire truing or resurfacing, is less common in everyday use but can be applied in specialized racing or performance applications. It might involve shaving or grinding the tire surface to achieve a specific, uniform contact patch with the road or track, or to correct any imperfections from manufacturing or initial use. The aim is to ensure consistent grip and handling.

The process of wheel profiling typically involves specialized machinery that precisely grinds or machines the wheel to the desired profile specifications. Regular inspection and profiling are essential maintenance procedures in many industries where wheels are used under heavy loads or high speeds.
