Bearing ball bearing fault sound judgments

1: bearing steel ball production process:
1, grinding: the ball into the rough match with the rough size, upper and lower multi-channel measurements with the same concentric ring section slot grinding mill for the triangle, add oil, crude abrasives; on the disc rotation, the next disc Fixed. Ball machine, said more than rough mill. Necessary, coarse grinding can have Road.
2, system of embryos: use of a variety of processes to produce a variety of spherical rough way.
3, fine grinding: the completion of rough grinding fine grinding machine into the blank; adding low viscosity oils and fine abrasive, grinding to size;
4, Cleaning: Each completed a rough grinding, were to stick the ball abrasive surface of the residual crude oil and clean.
5, polishing: Process and coarse grinding, fine grinding similar.
After further heat treatment, shot peening treatment that some have and some do not. The last one is the polishing process is, and generally use the yes yes Yan grinding plus a combination of slurry, so that the manufacture of ball bearings out.
2: Sound Judgement bearing fault:

1, concave bearing outer orbit orbit dent will cause vibration, resulting in smooth crisp sound.
2, the bearings are well connected to the switch if the state will issue a muffled whining sound. If issued a sharp hissing sound, creak sound audio, and other irregular, often bearing is bad that even the transfer situation. Sharp squeaking noise may be due to inadequate lubrication caused. Bearing clearance will also result in improper metal sound.

3, if there are intermittent noise, then scroll parts may be damaged. This sound is occurs when damage to the surface to be rolling out of date, often bearing if pollutants cause hissing sound. Serious irregularities with the contractor and the damage will have a huge noise.
4, if the installment of wounds caused by the knocking noise will be generated, the noise will be as high or low speed bearings and different.
