Abstract:
1. A journal box rubber pad, comprising an upper wear liner, a lower wear liner, a rubber layer positioned between the upper wear liner and the lower wear liner and a thin layer rubber formed on the outer surfaces of the upper and lower wear liners respectively, characterized in that the rubber pad also comprises: a glue-injection hole comprising a cavity formed in the rubber layer, a first hole formed on the upper wear liner and a second hole formed on the lower wear liner; the cavity, the first hole and the second hole being communicated with each other; and a conductive mechanism placed in the glue-injection hole; the two ends of the conductive mechanism passing through the first hole and the second hole respectively and being in contact with two conducted apparatuses; wherein the conductive mechanism comprises: a first conductive pin with its head part passing through the first hole and the end surface of the head part extending out of the thin-layer rubber surface on the upper wear liner; a second conductive pin with its head part passing through the second hole and the end surface of the head part extending out of the thin-layer rubber surface on the lower wear liner; wires connected to the first conductive pin and the second conductive pin to realize the electric conduction between the first conductive pin and the second conductive pin; and a spring sleeved onto the wires, wherein the two ends of the spring contact with a base of the first conductive pin and a base of the second conductive pin to support elastically the first conductive pin and the second conductive pin.
