Gear fault detection equipment

The utility model provides gear fault detection equipment, which comprises a data acquisition instrument, a photoelectric rotating speed sensor, an eddy current displacement sensor, a driving motor, a transmission belt, four connecting shaft wheels, a laser transmitter and a laser receiver, and is used for detecting whether a gear has a fault or not. Dynamic balance detection and analysis are carried out on the gear through a photoelectric rotating speed sensor, an eddy current displacement sensor and a data acquisition instrument, and the fault part of the gear and the specific characteristics causing the unbalance amount are accurately judged through the dynamic balance error amount. Through cooperative work of two adjusting cross beams, a driving motor, a transmission belt, four connecting shaft wheels, a connecting shaft and two check rings, the equipment can be flexibly adjusted so as to cooperate with gears of different sizes for detection. 本实用新型提供一种齿轮故障检测设备，包括：数据采集仪、光电转速传感器、电涡流位移传感器、驱动电机、传动带、四个连轴轮、激光发射
