Detailed Description
(Inner Ring) Track Pitch & Outer Diameter Concentricity Gauge is a comparative measurement jig configured to check the pitch quality of the track and the concentricity of the outer diameter of an inner ring component in a single device.
Track pitch is used to manage the uniformity of repeated position intervals or segments in the track geometry based on specific criteria. Track pitch deviations can lead to uneven contact locations, resulting in uneven load distribution, increased noise/vibration during rotation, uneven wear, and reduced durability.
Outer diameter concentricity measures how closely the inner ring's outer diameter center axis aligns with the reference axis. Defects can lead to eccentric rotation, increased runout, and reduced assembly quality. Especially for components where the track is a functional surface, simultaneous tracking of track quality and outer diameter alignment is essential for isolating the cause and rapidly stabilizing the process.
The measurement principle is to establish a zero point based on a sample master, then read only the deviation. First, an approved sample master is selected, mounted and secured in the jig, and the gauges are set to zero on both the track pitch measurement unit and the outer diameter concentricity measurement unit. After the measurement target is seated and fixed under the same conditions,
1) Track Pitch Measurement: A dedicated track contact (ball/probe) is placed in contact with the track section under specified conditions. The gauge change is read through rotation or movement to determine the pitch deviation trend.
2) Outer Diameter Concentricity Measurement: After positioning the contact on the outer diameter measurement section, the part is rotated and the difference between the maximum and minimum values is read to determine the outer diameter eccentricity trend.
This complex inspection jig allows for continuous inspection of two parameters under a single seating condition, reducing inspection time and facilitating the isolation of track-related or outer diameter eccentricity issues.
This product applies the latest technology to provide high precision and reliability. It delivers stable performance even under demanding measurement conditions required in industrial environments, and features a user-friendly interface that anyone can easily use.
Key Features
- Continuously measuring track pitch and outer diameter concentricity on a single device reduces inspection time and work flow.
- Zero-point setting based on the sample master ensures high inspection consistency and facilitates deviation trend management.
- The track-specific contact structure ensures stable contact with the track measuring section and ensures repeatability.
- The rotational displacement method after outer diameter contact allows intuitive confirmation of outer diameter eccentricity, making operator judgment easier.
- Basic tolerance standard (negotiable): ±0.003 mm
