Super-large bearing vibration noise quality detector

Abstract

The invention discloses a super-large bearing vibration noise quality detector and belongs to the field of mechanical detecting equipment. A driving mechanism is connected with a main shaft through a main shaft transmission mechanism. The main shaft is provided with a spring mould in a sleeved mode. A bearing is arranged in the spring mould. A locking nut is used for locking the bearing. An auxiliary loading and unloading mechanism is placed below the bearing and supports the bearing. A radial loading mechanism is placed above the bearing and adds radial load on the bearing. An axial loading mechanism is placed on the extending line of the axis of the main shaft and adds radial load on the bearing. A sensor adjusting mechanism fixed on a machine body is connected with a vibration sensor which is in contact with the outer circle of the bearing. An electric control system is connected with the driving mechanism and controls bearing rotating speed. Data measured by the vibration sensor are transmitted to the electric control system. Detectable large bearings are multiple in type and large in size, a main transmission part is supported by the precision bearing so that high detecting speed can be achieved, and meanwhile when a large bearing with a high weight is detected through the auxiliary loading and unloading mechanism, simple loading and unloading can be achieved, and detecting difficulty is lowered.

Description

technical field [0001] The invention relates to a super-large bearing vibration and noise quality inspection machine, which belongs to the field of mechanical inspection equipment. Background technique [0002] At present, because there are no dynamic quality inspection specifications and acceptance standards for super-large bearings d>120mm in my country, the existing bearing vibration measuring instruments are mainly for small and medium-sized bearings, and large-size bearing products are not tested for vibration quality before they are delivered to customers. Testing, which brings hidden dangers to the product quality of bearing enterprises, seriously affects the market share of bearing enterprises, and at the same time, because of the inability to simulate the situation in the application field, the lack of basis restricts the design innovation and transformation of large-scale bearing products, and the improvement of production control process Wait.
