Abstract

The invention discloses a comprehensive measurement device for bearing rigidity and starting friction torque, including a driving shaft, an inner axial pressure conduction block, an outer axial pressure conduction block, a pressure sensor and locking nuts. The driving shaft comprises a first step, a second step which is used for clamping a bearing, a testing end and a fastening end, and the testing end and the fastening end are provided with outer threads. The inner axial pressure conduction block is sleeved on the first step and is provided with a groove. The outer axial pressure conduction block is provided with a projection cooperated with the groove. The pressure sensor is sleeved on the driving shaft, and the end surface of the pressure sensor is adhered to the end surface of the inner axial pressure conduction block. The locking nuts are fixedly connected at two ends of the driving shaft respectively. The comprehensive measurement device for bearing rigidity and starting friction torque obtains the pretightening force, rigidity and starting friction torque of a single bearing or bearings in pair with one measurement device.

Description

technical field [0001] The invention relates to the technical field of bearing measurement, in particular to a comprehensive measurement device and measurement method for bearing stiffness and starting friction torque. Background technique [0002] The application of bearings in the drive train of gearboxes or reduction boxes is very common, and the bearings are generally arranged in pairs. The axial preload of the bearing involves three crucial parameters: stiffness, preload and starting friction torque; however, how to obtain the relationship between the above three parameters at the same time through actual testing means is not mature in the current industry. application precedent. Therefore, it is necessary to develop a device that can simultaneously measure bearing stiffness, preload and starting friction torque. Contents of the invention [0003] The purpose of the present invention is to provide a comprehensive measuring device and method for bearing stiffness and...
