Rubber pad for steel track

A rubber pad for a steel track, coupled to the steel track including a plurality of links and provided with a bushing engaging with a sprocket to allow driving of equipment, the rubber pad comprising

• a rubber pad body configured to be coupled to an outside of one of the plurality of the links;
• a fastening hole disposed in the rubber pad body to receive a bolt for coupling the rubber pad to the one of the plurality of the links;
• and
• a foreign substance discharging groove disposed on a first outer surface of the rubber pad body and indented toward a center of the rubber pad body,
• wherein the fastening hole includes a fastening portion to which the bolt is fastened, a step portion disposed on an inner surface of the fastening hole, or an inclining surface connecting an upper end of the fastening portion to an upper end of the fastening hole,
• wherein the step portion comprises one or more steps configured to facilitate removal of foreign substances stuck in the fastening hole,
• wherein the inclining surface radially extends from the upper end of the fastening portion to the upper end of the fastening hole,
• wherein a bottom surface of the foreign substance discharging groove inclines downward from an inner side to an outer side of the rubber pad body, and either side surface of the foreign substance discharging groove widens from inside to outside, and
• wherein a bushing cover is disposed on the rubber pad body and is positioned to face a foreign substance discharging groove of an adjacent rubber pad such that at least a portion of the bushing cover is configured to be accommodated inside the foreign substance discharging groove of the adjacent rubber pad.

A rubber pad for a steel track, coupled to the steel track including a plurality of links and provided with a bushing engaging with a sprocket to allow driving of equipment, the rubber pad comprising:

• a rubber pad body configured to be coupled to an outside of one of the plurality of the links;
• an iron core provided inside the rubber pad body in a right/left width direction of the rubber pad body;
• and
• a foreign substance discharging groove disposed on a first outer surface of the rubber pad body and indented toward a center of the rubber pad body,
• wherein either end of the rubber pad body is provided with a rubber pad end surface formed in a driving direction of the steel track and a rubber pad inclining surface inclined from front and rear ends of the rubber pad end surface toward a middle of the rubber pad body,
• wherein either end of the iron core includes an iron core end surface extending in parallel with the rubber pad end surface at a first interval and an iron core inclining surface extending in parallel with the rubber pad inclining surface at a second interval, and
• wherein the first and second intervals are 0.5 to 1.5 times a distance between the rubber pad end surface and the iron core end surface disposed in a driving direction of the rubber pad body,
• wherein a bottom surface of the foreign substance discharging groove inclines downward from an inner side to an outer side of the rubber pad body, and either side surface of the foreign substance discharging groove widens from inside to outside, and
• wherein a bushing cover is disposed on the rubber pad body and is positioned to face a foreign substance discharging groove of an adjacent rubber pad such that at least a portion of the bushing cover is configured to be accommodated inside the foreign substance discharging groove of the adjacent rubber pad.
