Problems solved by technology
There are two main types of existing testing equipment for dynamic balance of small rotors: one is automatic and precise testing equipment. Although this kind of equipment has high detection accuracy, it does not require such precise testing results for small rotors. And the equipment cost is too high; the other is a relatively simple semi-automatic equipment, but the clamping of the rotor of this equipment is not firm, and it is easy to generate vibration, which affects the test results

Disclosed in the invention is a dynamic balance detector for a rotor. The dynamic balance detector comprises a rack. A base plate and a fixed seat are arranged on the rack. A rotor positioning unit is installed on the fixed seat. Besides, a sensor is installed on the rack. A fixed rack arranged above the base plate is hinged to the base plate. A plurality of transmission wheels are arranged on the base plate and the fixed rack in a rotatable manner. In addition, a driving wheel and a motor for driving the driving wheel to rotate are arranged on the base plate. The driving wheel, the transmission wheels, and the rotor are in transmission connection by a belt. The rotor positioning unit includes an axial positioning mechanism and a radial positioning mechanism. The vibration of the rotor can be reduced effectively and an accurate detection result can be obtained. Moreover, the detector provided by the invention having advantages of simple structure and low manufacturing cost is suitable for dynamic balance detection of a small rotor. Furthermore, a supporting bearing is used as one part of the radial positioning mechanism, so that the rotation friction force of the rotor can be reduced effectively and thus vibration is reduced.
Description
technical field [0001] The invention relates to a rotor dynamic balance detector. Background technique [0002] The unbalanced rotation of the rotor is one of the main causes of excessive vibration and noise of the rotor, which will directly affect the working performance and service life of the engine. There are two main types of existing testing equipment for dynamic balance of small rotors: one is automatic and precise testing equipment. Although this kind of equipment has high detection accuracy, it does not require such precise testing results for small rotors. And the equipment cost is too high; the other is relatively simple semi-automatic equipment, but the clamping of the rotor of this equipment is not firm, and it is easy to generate vibration, which affects the detection results. Contents of the invention [0003] The present invention aims to solve the technical problems mentioned above, and provides a rotor dynamic balance detector, which has a simple structu...
