Abstract

The invention provides a pressure measuring device which comprises a bearing, a bearing housing and a force sensor, wherein the bearing is arranged inside the bearing housing; and the force sensor is arranged at the outer side of the outer ring of the bearing or is arranged on the bearing housing. According to the pressure measuring device, the force sensor is clung to the outer ring of the bearing or is arranged on the bearing housing, the tensile force is measured in an indirect measurement mode, and the pressure measuring device is simple in structure and low in cost; as the pressure measuring device is arranged on a fixing component, normal operation of equipment is not affected, and meanwhile a relatively accurate metering value is ensured; due to a force sensor mounting position, the situation that the bearing is interfered when the force sensor is mounted and is fixed through a key is avoided, and good fixation of the bearing is achieved; since a bearing wrapping angle and a partition plate thickness are reasonably set up, mounting reliability and stability of the bearing are ensured, deformation of the fixing component is well controlled, the measurement range of force is controlled, and relatively high sensitivity is maintained.

Description

technical field [0001] The invention belongs to the field of sensors, in particular to a pressure measuring device. Background technique [0002] The pressure sensor is one of the most commonly used sensors. According to the principle, it can be divided into strain gauge type and spring type. However, the existing pressure sensors usually require the measured object to be relatively fixed with the sensor. For example, the contact of the strain gauge needs to be connected by wires. When the shaft rotates, it is usually impossible to use or use a slip ring for connection. But at this time, the life of the sensor will be affected by the construction of the slip ring, and the reliability is not However, there is a lack of a pressure measuring device suitable for operation or movement. Contents of the invention [0003] In view of this, in order to overcome the deficiencies of the prior art, the present invention provides a pressure measuring device, by placing the sensor exte...
