Problems solved by technology

It is a common method to indirectly deduce the friction force of the hinge by measuring the torque that makes the hinge rotate at a uniform speed, but this measurement method is relatively indirect and will inevitably affect the measurement accuracy. This method cannot be used for swing hinges.
The accurate measurement method is to measure the tangential force of the two contact surfaces when the hinge moves through the sensor, but the sensor is complicated and the measurement is difficult

Embodiment Construction

[0014] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0015] Combining Figures 1 and 2, the composition of the swing hinge friction measurement device includes a bracket 1, a coaxiality indicator arm 2, a bearing seat 3, pressure sensors 4 and 5, the swing side 6 of the hinge, the measurement side 7 of the hinge, the swing arm 8. Crank 9 and motor 10; wherein, the coaxiality indicator arm 2 is used to identify whether the rotation axis of the swing arm 8 coincides with the hinge; the bearing seat 3 supports the rotating shaft of the swing arm 8; the swing side of the swing arm 8 and the hinge 6 is fixed; when the hinge is installed, it is necessary to ensure that the rotation axis of the swing arm 8 coincides with the rotation axis of the hinge, but the two rotation axes are separated; the pressure sensors 4 and 5 are fixed on the bracket 1, and the measuring heads are respectively squeezed on the Both sides of the h...

Abstract

The invention provides a friction measuring device for a swinging gemel and includes a supporter. The upward side of the supporter is provided with a bearing seat and two force sensors. A motor is arranged below the supporter. An output shaft of the motor is fixedly connected with a curved shaft and the other end of the curved shaft extends to a pin roll in a sliding slot on an oscillating arm. The other end of the oscillating arm is arranged on the bearing seat through an oscillating arm rotary shaft. The swinging side of the gemel is fixedly connected with the oscillating arm and is fixedly connected with a gemel rotary shaft. The measuring side of the gemel is arranged on the gemel rotary shaft. The measuring heads of the two force sensors are respectively extruded at two sides of the measuring side of the gemel. When the invention is used for measuring the friction, as the measuring side of the gemel does not move, the inertia force is not affected. The moment measured by the sensor is the friction moment of the gemel and the measuring result is accurate. The structure of the device is simple and the measuring is convenient.

Description

(1) Technical field [0001] The invention relates to a force measuring device, in particular to a swing hinge friction measuring device. (2) Background technology [0002] Generally speaking, the influence of friction on the movement of mechanisms cannot be ignored. Therefore, it is necessary to measure the friction of various mechanisms. But for various reasons, friction has always been a difficult point to measure. [0003] There are many methods for measuring friction force at present, but for different institutions, the measurement methods and devices are also different. For example, the patent application number is 200520102383.X, and the technical solution disclosed in the utility model patent application document named Bearing Micro-Load Friction Measuring Device can accurately measure the friction force and friction coefficient of sliding bearings and rolling bearings. But there is no special device for measuring the frictional force of the swing hinge. It is a com...
