Measurement of tapered roller bearings

Tapered roller bearing

Conical roller bearings can withstand large radial and thrust mixed loads, or only thrust loads. Due to the difference in contact angle between the internal and external channels, there exists a force that pushes the tapered roller towards the direction of the guide pipe flange. If special coolant/lubricant is not considered, significant sliding friction will be generated on this flange, making this type of bearing unsuitable for high-speed applications. Typical applications include construction machinery, gear structures, vehicle manufacturing, and rolling mills.

The surface roughness of the raceway and rolling components is crucial for the operational performance and noise characteristics of such bearings. Taylor Hobson has many Form Talysurf inductance series instruments suitable for measuring the surface roughness characteristics of tapered roller bearings.

In addition, the roundness and waviness of the raceway and rolling components are also very important. Usually, we use roundness measuring instruments to measure these characteristics.

In addition to analyzing general geometric features, it is also necessary to analyze the cross-sectional shape of the bearing raceway and rolling components. These sections are usually raised (cylindrical) to avoid peak stress at the edges of the bearing. This shape can be defined in various ways, including simple large radii or mathematical equations. You can use TAYLOR HOBSON's specialized geometry software to analyze these shapes.
