  • Self-lubricating structure for use in an exerciser
    Publication number: 20040266590
    Abstract: The present invention relates to a self-lubricating structure, particularly for use in a treadmill. The structure is provided with reservoirs formed in the front and rear rollers which actuate a running endless belt, in which the reservoirs are filled with lubricant, such as silicon oil. A porous nozzle is formed in an opening on a top of each of the reservoirs, such that the silicon oil in the reservoirs is dripped from the nozzle, by means of the eccentric force generated by rotation of the rollers, to lubricate the running endless belt in order to facilitate the operation of the treadmill.
