The invention relates to a measuring machine for dynamic friction torque characteristics of a tapered roller bearing, which comprises a machine frame, an axial loading device and a rotating spindle device. The loading shaft loading end of the axial loading device and the rotating spindle driving end of the rotating spindle device forms coaxial and relatively rotatable connection via a tapered roller bearing to be tested. The rotating spindle is provided with a non-contact flange type torque sensor. One end in the rotor shaft direction of the non-contact flange type torque sensor is coaxially fixedly connected with the rotating spindle and synchronously rotates with the rotating spindle, and the other end in the rotor shaft direction of the non-contact flange type torque sensor is coaxially fixedly connected with a bearing mounting base to be tested. The stator of the non-contact flange type torque sensor is correspondingly matched with the lateral part of the rotor. In the above scheme, there is only one rotating component in the shaft system consisting of the tapered roller bearing to be tested and the torque sensor, so as to avoid generating the corresponding additional torque and improve the accuracy of the test result; and in addition, the friction torque detection is achieved under a condition that the axial load is continuously changed.
Description
Technical field [0001] The present invention relates to a bearing detection device, specifically a measuring device for detecting the friction torque of a tapered roller bearing. Background technique [0002] Tapered roller bearings are separable bearings. Both the inner and outer rings of the bearing have tapered raceways. The friction torque of tapered roller bearings includes the friction torque (dynamic friction torque) that needs to be overcome when the inner and outer rings of the bearing rotate relative to each other, and the maximum friction torque (starting friction torque) that the inner and outer rings of the bearing need to overcome when they are stationary to start relative rotation. With the development of technology, the requirements for tapered roller bearings are getting higher and higher. The friction torque of tapered roller bearings affects the noise, energy loss, working life and so on of the equipment. [0003] At present, the structural design of the frictio...
