Abstract
The invention discloses a rotation speed difference measuring device. Two independent photoelectric sensors and a light reflecting tape are adopted; the photoelectric sensors have the functions of light source and reflection light detection; and the light reflecting times while the shaft rotates for each circle can be adjusted through the light reflecting tape. The installing method comprises the following steps: the sensors are respectively installed on box bodies through brackets, wherein two shafts are arranged on the box bodies; and the light reflecting tape is adhered to the shaft bodies at the positions corresponding to the sensors. During working, the sensors emit continuous light to irradiate the light reflecting tape so as to generate reflecting light; the reflecting light is picked up by the sensors to be used as pulse signal counting; the pulse counting can be output as rotation speed values of the shafts after being subjected to certain calculation; and precise value of the rotation speed difference of the two shafts can be obtained by comparing the pulse counting of the two shafts corresponding to the sensors. The rotation speed difference measuring device is in a mode of non-contact type measurement and is hardly influenced by the environment condition; the measurement precision can reach an extremely high level; the continuous online monitoring can be realized; the rotation speed difference measuring device is particularly suitable for places of unattended operation; and the components adopted by the rotation speed difference measuring device are easy to realize and have good economy.
