Description

Measuring device for centering and aligning flange pin type coupling

Technical Field

The utility model belongs to the technical field of alignment of couplings, and particularly relates to a measuring device for alignment of a flange pin type coupling.

Background

The flange coupling is connected with the shaft by a common flat key, and then the two half couplings are connected into a whole by an elastic pin so as to achieve the effects of transmitting motion torque and buffering and absorbing vibration.

The uneven thermal expansion of the parts at the two ends of the connecting shaft, the deflection of the shaft, the uneven wear of the bearing, the displacement generated by the machine, the uneven sinking of the foundation and the like are all causes that the shaft centering is not easy to keep. The flange pin type coupling has the functions of compensating offset, relieving impact and absorbing vibration between two shafts, which are caused by inaccurate manufacturing and installation, deformation or thermal expansion during working, and the like. The offset includes an axial offset, a radial offset, an angular offset, or a combined offset. Thus, an allowable deviation value of the centers of the two shafts is specified during installation, which is also required for installing the coupling.

The alignment of the flange coupler is one of important works for machine installation, and the purpose of the alignment is to enable the central lines of the two shafts of the driving shaft and the driven shaft to be on the same straight line as much as possible in the allowable deviation value, so that the smaller the central line deviation of the two shafts is, the more accurate the alignment is, the better the running condition of the machine is, and the longer the service life is.

The coupler centering device disclosed by the utility model can solve the problem of displacement of the magnetic meter base in a vibration environment, can be used for centering a coupler with a large span, and is inconvenient to use in a narrow and inconvenient observation space.

In the prior art, common coupler alignment tools such as dial indicators and the like are difficult to apply to coupler alignment work in narrow and inconvenient observation space, such as vertical long-axis pump coupler alignment work. To this end, the present application provides a measuring device for centering and aligning a flanged pin coupling.
