Description

Automatic oiling device for running belt

The invention relates to a running belt, in particular to an automatic oiling device for the running belt.

In order to reduce the friction between the running belt and the running board, general treadmills usually apply lubricating oil on the running belt or the running board before assembling.

An existing running belt oiling method requires a running belt to be wrapped around several rollers, part of the running belt and one of the rollers are immersed in an oil tank filled with lubricating oil, and then by rotating the belts. The rollers drive the running belt to rotate around the rollers, so that each part of the running belt can be sequentially immersed in the lubricating oil.

However, the conventional running belt oiling method is not easy to control the amount of lubricating oil, and it is easy to cause the running belt to be contaminated with too much lubricating oil and contaminate other rollers or drip onto other components. In addition, the two opposite sides of the running belt will be stained with lubricating oil, so it needs to be processed to remove the lubricating oil on one side before it can be installed.

Therefore, the object of the present invention is to provide an automatic lubricating device for running belts that can uniformly apply lubricating oil to the inner peripheral surface of the running belt.

The tensioning wheel is axially arranged on the movable seat and can be driven to move by the movable seat. The tensioning wheel, the driving shaft and the first driven shaft jointly define a working space with a variable cross-sectional area and suitable for winding the running belt. The tension wheel can move between an installation position and a working position. In this installation position, the working space has the smallest cross-sectional area.

In this embodiment, the angle θ is between 45 degrees and 90 degrees.

Referring to Figures 2, 4, and 6, when using, the user needs to operate the mobile module 24 to make the tensioning wheel 5 in the installation position (see Figure 6). Since the working space 800 has the smallest cross-sectional area, it can The running belt 1 is easily wound around the driving shaft 3, the first driven shaft 41, the tension wheel 5, the second driven shaft 42 and the third driven shaft 43.

Continue to operate the moving module 24 to make the tensioning wheel 5 in the working position (see FIG. 4), so that the driving shaft 3, the first driven shaft 41, the tensioning wheel 5, and the second driven shaft 42 and the third driven shaft 43 force the inner circumferential surface 11 of the running belt 1, and then operating the driving unit 6 to drive the driving shaft 3 to rotate can drive the running belt 1 to rotate relative to the base 22, Finally, the control module 73 is operated to spray lubricating oil on the inner circumferential surface 11 of the running belt 1 through the nozzles 72 to complete the oiling operation of the running belt 1.

Referring to Figures 2, 5, and 7, during the aforementioned oiling process, sometimes the running belt 1 may have different inner circumferences on the opposite sides along the third axis Y due to manufacturing tolerances or other factors. Before operating the driving unit 6 to drive the running belt 1 to run, one of the gripping portions 281 can be rotated to drive the threaded portion 282 to rotate, because the limiting portions 283 are fixed to the threaded portion 282 and are located at their respective first positions. A plate portion 263 is on opposite sides of the second axial direction X, so that the threaded portion 282 can only rotate relative to the respective first plate portion 263 and cannot move along the second axial direction X, and the threaded portion During the rotation of 282, the side of the pivot 27 adjacent to the threaded portion 282 will be relative to the seat 26 along the second axial direction X due to the engagement between the respective locking holes 272 and the threaded portion 282. Move, so that the first driven shaft 41 sheathed outside the pivot shaft 27 is inclined to conform to the inner circumference of the running belt 1. For example, by operating the adjusting members 28 to move the first driven shaft 41 to the imaginary line position as shown in FIG. 7, it can provide a running belt 1 with a relatively short inner circumference on the right side (not shown in FIG. 7) use. Similarly, when the inner circumference of the left side of the running belt 1 is relatively short, the adjustment members 28 can also be operated to make the end of the first driven shaft 41 on the left side of FIG. 7 relatively adjacent to the driving shaft 3. Through the above-mentioned adjustment steps, the two opposite sides of the running belt 1 will receive a uniform compression force, so that the subsequent process of the driving unit 6 driving the running belt 1 to run is more stable.

In addition, since the guiding member 713 of the oiling unit 7 can drive the nozzles 72 to move relative to the guiding plates 711 along the second axis X, after adjusting the adjusting members 28 according to the above steps, The guide 713 can also be adjusted to move the nozzle 72 to a suitable position before spraying lubricating oil (for example: move the nozzle 72 to the position shown by the imaginary line in FIG. 7), so that the lubricating oil can be more uniform The ground is distributed on the inner circumferential surface 11 of the running belt 1.

It is worth mentioning that in this embodiment, the running belt 1 is driven by the driving shaft 3, the first driven shaft 41, the tension wheel 5, the second driven shaft 42 and the third driven shaft. The shaft 43 is forcibly supported. However, in other embodiments, the second driven shaft 42 and the third driven shaft 43 may not be provided, as long as the driving shaft 3, the first driven shaft 41 and the The tightening wheel 5 can force the running belt 1 and define the working space 800 for the oiling unit 7, and the same effect can be achieved.

In summary, by providing the driving shaft 3, the first driven shaft 41, the tensioning wheel 5, the second driven shaft 42 and the third driven shaft 43, the running belt 1 can be wound around Set and define the working space 800 for the oiling unit 7, and when the tensioning wheel 5 is in the working position, the tensioning wheel 5, the driving shaft 3, the first driven shaft 41, and the second The two driven shafts 42 and the third driven shaft 43 force the inner circumferential surface 11 of the running belt 1, and then the driving unit 6 drives the running belt 1 to run, so that the inner circumference of the running belt 1 The surface 11 is completely coated with lubricating oil, so the purpose of the invention is indeed achieved.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited by this, all simple equivalent changes and modifications made in accordance with the scope of the patent application of the present invention and the content of the patent specification still belong to Within the scope covered by the patent of the present invention.
