Fishing reel bearings vibration velocity standard

Vibration velocity standard for fishing reel bearings:
Due to the original vibration acceleration standard has not been abolished, so the standard is issued by the ministry of machinery industry standards, is a reference to the European standards combined with the actual situation and the need to develop, to detect the fishing bearings vibration speed to determine the quality of the fishing bearings grade (equivalent to the national standard).Divided into V, V1, V2, V3, V4 five quality levels.

Fishing reel bearings in operation, although ISO2372 standard is excessive vibration velocity to determine, but in the actual to pay special attention to the change of fishing reel bearings acceleration value, bearing damage process is mostly the early performance for fatigue damage, it can generally show the obvious acceleration increases, with the development of fatigue, vibration velocity and displacement increases gradually, heralds bearing in the fatigue damage.

Especially for bearings detection, it is necessary to carefully pay attention to whether the vibration value swings unsteadily (it is recommended to use analog pointer instrument, which can be observed very clearly). If the vibration appears, it indicates the occurrence of unstable vibration signal, and the acceleration is also large.
For new equipment, acceptance testing, while the vibration is very small, in line with the national standard, but in the vibration of fishing reel bearings parts appear small oscillation phenomenon, eliminate fishing reel bearings after (play) with problem, probably fishing reel bearings geometry problems, such as bearing rims ellipse, rolling body after a long axis of the ellipse, may be caused by gap decrease instant card roller die, subsequent continued squeezing roller, make the rolling body produces sliding friction, each will appear in the sliding friction roller, cause the unstable signal.
