With a thrust indicator Fluid type pressure gauge (Pressure gauge with thrust indicator)

摘要

It is aimed to make it possible to easily see the thrust of the pushing part that presses the part with fluid pressure in the thrust pin, which is proportional to the fluid pressure, so that it is unnecessary to use the expensive torque gauge with torque gauge. a pressure piece 1c which is mounted on the shaft a for fastening the shaft b and which pressurizes the part b mounted on the shaft a by fluid pressure is provided, A cylinder chamber 3 communicating with an enclosed fluid passage 1d in which a fluid for pressing the pressure piece 1c is sealed is provided in the fluid pressure bearing device 1 and a piston 3a is provided in the cylinder chamber 3 A spring 5 is installed to urge the piston 3a, which has a built-in perturbation material, and which has one end of the thrust pin 4 attached to the piston 3a, against the fluid pressure, with a constant spring constant And simultaneously with the piston 3a that fluctuates in proportion to the fluid pressure, the other end of the thrust pinion 4 Kane was installed protruding material.
