Abstract

A lubricating apparatus for an endless moving belt of an electric treadmill includes a base frame with a U-shaped groove laterally extended across the base frame. The U-shaped groove is filled with felted wool in which lubricant is contained. After assembly of the above-mentioned components, the felted wool within the U-shaped groove is in constant contact with the bottom surface of the endless moving belt, thereby ensuring a reliable and long-term lubrication.

Claims

1. A lubricating apparatus for an endless moving belt of an electric treadmill, the treadmill having a base frame with a U-shaped groove laterally extending across the base frame, the U-shaped groove being filled with felted wool in which lubricant is contained

whereby, after assembly of the above-mentioned components, the felted wool within the U-shaped groove is in constant contact with the bottom surface of the endless moving belt, thereby ensuring a reliable and long-term lubrication.

2. The lubricating apparatus for an endless moving belt of an electric treadmill of claim 1, wherein a refill tube is enclosed by the felted wool while the refill tube is formed with a plurality of oil outlets, and wherein the refill tube includes an oil filling hole disposed at the external side of the U-shaped groove.

3. A lubricating apparatus for an endless moving belt of an electric treadmill, the treadmill having a base frame with a U-shaped groove laterally extending across the base frame, the U-shaped groove being pivotally attached by pivoting shafts to the base frame, the U-shaped groove being filled with felted wool in which lubricant is contained, the elastic elements are fitted to the bottom of the U-shaped groove in order to push up the U-shaped groove for a constant contact with the corresponding surface of the endless moving belt,

whereby, after assembly of the above-mentioned components, the felted wool within the U-shaped groove is in constant contact with the bottom surface of the endless moving belt, thereby ensuring a reliable and long-term lubrication.

4. The lubricating apparatus for an endless moving belt of an electric treadmill of claim 3, wherein a refill tube is enclosed by the felted wool while the refill tube is formed with a plurality of oil outlets, and wherein the refill tube includes an oil filling hole disposed at the external side of the U-shaped groove.
