How to judge whether the cycloidal wheel of XWDY8095-29-0.37KW reducer needs straightening

To determine whether the cycloidal wheel of the XWDY8095-29-0.37KW reducer needs to be straightened, it mainly depends on whether the deformation exceeds the allowable range, and is comprehensively evaluated based on the operating status and detection data. The following are the specific judgment methods and steps:

1. Deformation detection and standards

‌1. Straightness measurement‌

Use a dial indicator or laser interferometer to measure the straightness of the cycloidal gear tooth surface. The allowable deviation is usually ≤0.01mm/m.

If the deformation is out of tolerance (such as >0.02mm/m), straightening is required.

2. Coaxiality measurement‌

Use a table method or a three-dimensional coordinate measuring machine to measure the coaxiality of the meshing surface between the cycloidal wheel and the pin teeth. The allowable deviation is generally ≤0.01mm.

If the coaxiality is out of tolerance (such as >0.015mm), straightening is required.

2. Observation of operating status

‌1. Vibration and noise‌

If the equipment vibrates significantly or the noise increases during operation, it may be caused by deformation of the cycloidal wheel and poor meshing.

2‌. Transmission efficiency‌

The transmission efficiency decreases (such as the output speed fluctuation >5%), and the meshing accuracy may be affected by deformation.

3. Detection Tools and Methods

‌1. Contact measurement‌

Use a dial indicator to measure the tooth surface runout, and the allowable deviation is ≤0.01mm.

2‌, non-contact measurement‌

Use a laser interferometer to measure straightness, with an accuracy of up to 0.001mm.

4. Comprehensive assessment

Straightening is required when the deformation is out of tolerance or the operating status is abnormal.

If the deformation is slight (such as straightness 0.01–0.02mm/m), cold straightening can be attempted; if the deformation is severe (such as >0.02mm/m), hot straightening or replacement is recommended.

5. Things to note

After straightening, the straightness, coaxiality and hardness need to be re-measured to ensure that the performance meets the standards.

If the deformation is accompanied by cracks or insufficient hardness, the cycloidal wheel needs to be replaced.
