Vibration measurement component with precise positioning device for motion sensing parts in height direction

Abstract

The invention discloses a vibration measurement assembly with a precise positioning device for a motion sensing element in the height direction, comprising: a body having a reference plane and an orthogonal setting plane perpendicular to the reference plane, the orthogonal setting plane has a plurality of distances away from each other The insertion port, and the distance between the insertion ports corresponds to the outer dimension of the above-mentioned motion sensing element in the height direction; the circuit board of the motion sensing element in the height direction is electrically welded; the positioning device includes: the plural shapes are respectively complementary to the insertion ports and a fixing unit whose size is not smaller than the above-mentioned corresponding insertion port, for being tightly coupled to the corresponding insertion port; and a pressing base extending from the fixing unit, having a butt surface close to the body and a back surface opposite to the abutment surface, the butt surface There is an abutting part on the top, which is used for abutting and holding the circuit board together with the above-mentioned height direction motion sensing element between the pressing base and the main body.

Description

technical field [0001] The invention relates to a vibration measuring assembly, in particular to a vibration measuring assembly with a precise positioning device for a height-direction motion sensing element. Background technique [0002] Any equipment that rotates around a center can be called rotating equipment, ranging from fans, motors, pumps, and compressors commonly found in factories to wind turbine shafts and high-speed MRT train axles. Because any rotating equipment cannot be in a perfect true circle, there will be eccentric rotation of different degrees during operation, which will generate some reciprocating force and cause the rotating equipment to vibrate. Therefore, the vibration generated by the above-mentioned actions can be monitored. behavior to determine the condition of the above-mentioned rotating equipment. For rail vehicle applications, the minimum vibration of 1mG needs to be monitored regularly. In the past, the transmission shaft of rail vehicles h...
