Embodiment Construction

[0022] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0023] A device for simultaneously measuring the axial and radial displacement of a rigid coupling, such as figure 1 As shown, it includes a support rod 2, an axial measuring device 6 arranged on a bracket 7 for measuring axial deviation, and a radial measuring device 5 for measuring radial deviation.

[0024] The support rod 2 is threaded through the corresponding bolt holes of the two half-couplings during measurement, and the outer circumference of the support rod 2 is threaded. A pair of nuts I3 are arranged on the support rod 2, and the nuts I3 are located on both sides of the rigid coupling 1, and are fixedly connected to the support rod 2 and the rigid coupling 1. In order to prevent the side end surface of the rigid coupling 1 from being damaged when the nut I3 is tightened, a flat washer I4 is arranged between the side end surface of the rigid ...

Abstract

The invention discloses a device for synchronously measuring axial displacement and radial displacement of a rigid coupler. The device comprises a supporting rod which is connected in opposite connecting holes of two half couplers in a penetrating mode, a support is fixedly installed on the supporting rod, an axial measuring device measuring the axial displacement of the coupler and a radial measuring device measuring the radial displacement of the coupler are arranged on the support, threads are arranged on the supporting rod, the supporting rod and the coupler are connected through a pair of nuts I which are arranged on the supporting rod and positioned on the two sides of the coupler, and the support is installed on the supporting rod in a sleeved mode and fixed through a pair of nuts II. The device is simple in structure and convenient to operate, by the adoption of the axial measuring device and the radial measuring device which are installed on the support, axial displacement deviations and radial displacement deviations of the rigid coupler can be measured simultaneously, accumulative errors caused by separated measuring are reduced to the maximum, and measurement accuracy is improved substantially.

Description

technical field [0001] The invention relates to a measuring tool used for equipment installation and alignment, in particular to a device for measuring the axial and radial displacement of a coupling. Background technique [0002] A coupling is a mechanical part used to connect two shafts in different mechanisms so that they rotate together to transmit torque. The coupling consists of two halves, which are respectively connected to the driving shaft and the driven shaft. There are many types of couplings, among which rigid couplings are widely used. They have the characteristics of maintenance-free, super oil resistance and corrosion resistance. Rigid couplings are composed of rigid force transmission parts. There is no backlash at all times, even if there is a load due to deviation, the rigid coupling still transmits torque rigidly. [0003] The adjustment of the coupling is one of the important tasks of machine installation. Adjust the position of the two halves of the c...
