Static balance, couple balance and dynamic balance measuring device with high separation ratio

Abstract

The invention discloses a static balance, couple balance and dynamic balance measuring device with a high separation ratio, belonging to the dynamic balance detection equipment. The external periphery of a vibration disk (2) is correspondingly provided with a permanent seat (3); the vibration disk (2) is respectively provided with a lateral torsional mechanism (4), a crookedly-swinging mechanism (5), a horizontal tension and compression sensing mechanism (6) and a vertical tension and compression sensing mechanism (7), wherein a horizontal tension and compression bar (61) in the horizontal tension and compression sensing mechanism (6) is provided with a horizontal sensor (63); a vertical tension and compression bar (71) in the vertical tension and compression sensing mechanism (7) is provided with a vertical sensor (73); and the horizontal sensor (63) and the vertical sensor (73) are respectively connected with a computer measuring and controlling system. The purposes of correcting static unbalanced force and coupled unbalanced force can be achieved. The measuring device has the advantages of high measuring precision, small detection error, simple complete machine structure, few parts and small volume, is convenient to operate and stable to operate, and the labour productivity and the economic benefit of static balance, couple balance and dynamic balance measurement and correction can be greatly improved.

Description

technical field [0001] The invention relates to a balance measuring device, in particular to a high separation ratio static and dynamic balance measuring device. It belongs to dynamic balance detection equipment. Background technique [0002] In the past, due to the low speed of industrial fans and the backwardness of the overall technical level, people did not pay much attention to the centrifugal inertial force caused by the uneven mass distribution of the fan during operation. Correction, without couple unbalanced force Fa correction. In the past, the operating speed of industrial fans was generally 1500 rpm, and only the static unbalance correction was done, which could barely handle it. [0003] Nowadays, with the rapid development of industrialization, people have higher and higher requirements for product performance indicators and quality of use. As far as industrial fans are concerned, not only the manufacturing quality requirements of industrial fans have been g...

Problems solved by technology

[0007] The object of the present invention is to provide a high-separation device that can complete the separation of the static unbalanced force Fr and the couple unbalanced force Fa for the existing dynamic unbalance detection method and device. Compared with the static couple dynamic balance measuring device, it has a higher separation ratio of static couple unbalanced force, simple structure, small size and convenient operation, which can greatly improve the efficiency of measurement, detection and correction, and is especially suitable for the static couple of ultra-thin rotors. balance measurement
