Description
Technical Field
The invention relates to a measuring shaft type structure bearing, in particular to a measuring instrument and a measuring method for vibration of a water pump bearing.
Background
Because the water pump bearing is special in structure, and in addition, a customer has no vibration detection requirement on the water pump bearing in the past, a manufacturer for producing the water pump bearing rarely carries out vibration detection on the water pump bearing. However, with the rapid development of bearing production technology, the requirements of customers on the quality and noise of water pump bearings are more and more strict, and in particular, in the last three or four years, almost all customers using water pump bearings have the requirements on vibration detection in water pump bearing production plants. At present, the detection of the water pump bearing adopts a traditional mandrel structure (see attached figure 4), the small end of a water pump bearing shaft is inserted into a mandrel, and meanwhile, a certain load force is applied to the small end (left channel) of the water pump bearing shaft and the radial direction to measure the comprehensive vibration result of the water pump bearing. The measurement method has many defects, when the water pump bearing is detected to have a fault, the fault of the left channel of the water pump bearing or the fault of the column end of the water pump bearing cannot be determined (the radial loading is used for measuring whether the column end of the water pump bearing has the fault), and the missing detection phenomenon exists at the same time, namely if the right channel of the water pump bearing has the fault, the missing detection cannot be carried out. The most important defect is that because the end face of the water pump bearing shaft is a blank surface, the positioning measurement is carried out by the blank surface, the stability of the measurement result and the measurement data is not ideal, the slippage between the mandrel and the water pump bearing shaft during the rotation can not be ensured, if the slippage occurs, the rotation speed of the water pump bearing shaft is reduced, and the measurement result is unreliable.
