Lubrication system for treadmill

Abstract

A treadmill having continuous solid lubrication system between the inner surface of the endless belt and the support deck. The treadmill has an endless belt entrained around a drive roller and an idler roller. The belt has a first or upper reach and a second or lower reach extending between the rollers. The belt has an outer surface and an inner surface. The endless belt encircles a support deck so that a user positioned on the outer surface of the upper reach is supported by the top side of the deck. The inner surface of the upper reach is in a sliding relationship with the deck. The continuous solid lubrication system is positioned below the deck in a downwardly orientated position. The solid lubrication system includes a solid wax in an elongated solid lubricant channel. The channel is attached at an angle to the under side of the deck so that the channel and the solid wax engage the inner surface of the lower reach of the belt. The belt abrades the solid wax and the channel as it moves along its continuous path imparting lubrication to the belt. As increased tension is applied to the upper reach, more lubricant is applied to the inner surface of the belt.
