Abstract

The invention provides a gear and belongs to the field of intelligent equipment. The gear comprises a gear body and a rotation speed detection device, wherein a groove is formed in the end face of thegear body, and the rotation speed detection device is embedded in the groove. The rotation speed detection device comprises a cubic shell, a first physical signal acquisition module, a second physical signal acquisition module, a third physical signal acquisition module, a steel needle, a Bluetooth module and a steel ball; the first physical signal acquisition module is fixed to the inner side ofthe upper surface of the cubic shell through the steel needle, and the second physical signal acquisition module and the third physical signal acquisition module are fixed to the inner side face of the cubic shell parallel to the normal vector of the gear body through the steel needle; the steel ball is embedded in the cubic shell, the outer surface of the cubic shell is provided with a small hole, the Bluetooth module is fixed into the small hole, and the steel ball is embedded in the cubic shell. The gear has the advantages of simple structure, high stability requirement and great transientresponse capability and is applicable to rotation speed monitoring of gears under a working condition which cannot be directly detected.

Description

technical field [0001] The invention belongs to the field of intelligent equipment, and in particular relates to a gear. Background technique [0002] A gear is a mechanical element with teeth on the rim that can continuously mesh to transmit motion and power. The application of gears in transmission has appeared very early. It is widely used in mechanical transmission and the entire mechanical field. With the development of production, the stability of gear operation has been paid more attention. The existing rotational speed detection device usually needs to rotate for a long time to detect the corresponding rotational speed, the detection efficiency is low, and the accuracy of rotational speed detection is low. [0003] For example, the pulse light source speed measuring device to detect the photoelectric tachometer can make the frequency signal source accurate to 10 -6 Even higher, however, the pulse light source is too strong, which may cause the inspectors to fail t...
