Bushing Installation Steps
(1) Clean the surface of the parts to be installed;
(2) Place the bushing in a cooling tank filled with liquid nitrogen for freezing. The freezing time varies according to the ambient temperature, generally 10 to 15 minutes. Specifically, the surface of the bushing is no longer obviously bubbling, and the heat exchange process is stopped.
(3) Immediately insert the bushing into the hole of the part to be installed after taking it out of the liquid nitrogen tank. Note that after the bushing is in place, the opening should be fixed with tools such as skids or calipers, so that the outer wall of the bushing at the opening can be tightly attached. Bore.
(4) After the expansion and deformation of the bushing are completed, check the installation quality of the bushing:
a) Detect whether there is a wrong edge at the opening of the bushing: If there is a wrong edge at the opening of the bushing, you can use a grinding wheel to partially grind it.
