Shaft pivoted hub bearing unit monitoring system for axial pivoting force and displacement and method

Abstract

The invention discloses a shaft pivoted hub bearing unit monitoring system for axial pivoting force and displacement and a method. The system comprises a pressure sensor, a transducer I, a displacement sensor, a transducer II, an A / D (Analog to Digital) conversion module, an industrial computer and a data processing module, wherein the pressure sensor and the transducer I are connected in sequence; the displacement sensor and the transducer II are connected in sequence; the transducer I and the transducer II are connected with the A / D conversion module respectively; and the A / D conversion module, the industrial computer and the data processing module are connected in sequence. By adopting the system, pivoting force-displacement data measured in each pivoting process can be recorded, the qualification of a shaft pivoting process can be judged automatically according to a measured pivoting force-displacement curve, possible causes leading to defective goods can be given automatically, and data can be counted and analyzed or called automatically. The system has an easy, convenient and practical technical means and positive and beneficial technical effects.

Description

technical field [0001] The invention belongs to the field of industrial product quality monitoring, in particular to a system and method for monitoring axial riveting force and displacement of a shaft riveting hub bearing unit. Background technique [0002] In recent years, the requirements for environmental protection have become higher and higher, especially the requirements for technologies such as energy saving, reliability improvement and cost saving have become increasingly prominent. In response to these requirements, shaft riveting instead of nuts has appeared in the assembly method of hub bearings. Snap-on trend. The inner and outer rings of the traditionally designed hub bearing unit are firmly connected together with lock nuts during assembly. The disadvantage of this method is that the axial direction of the hub unit needs to be controlled by controlling the pre-tightening of the nut during assembly. Clamping force, due to the manufacturing error of the parts in...
