Description

Running belt automatic oiling device

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

In order to reduce the friction between the running belt and the running board, the general treadmill usually smears lubricating oil on the running belt or the running board before assembly, and then assembles.

An existing way of lubricating a running belt requires that a running belt be wound around several rollers, and part of the running belt and one of the rollers be soaked in an oil tank filled with lubricating oil. The rollers drive the running belt to rotate around the rollers, so that each part of the running belt can be sequentially soaked in the lubricating oil.

However, it is not easy to control the amount of lubricating oil in the existing way of lubricating the running belt, and it is easy to cause the running belt to attach too much lubricating oil to contaminate other rollers or drip on other elements. In addition, lubricating oil will adhere to both opposite sides of the running belt, so it needs to be reprocessed to remove the lubricating oil on one side before installation.

Therefore, the object of the present invention is to provide a running belt automatic oiling device that can evenly apply lubricating oil to the inner peripheral surface of the running belt.

Therefore, the present invention provides an automatic oiling device for a running belt, which is suitable for applying lubricating oil to a running belt.

A tangent line defining the side of the first driven shaft 41 and the third driven shaft 43 opposite to the nozzles 72 is a first axis L1, and each nozzle 72 extends along the extension direction of a second axis L2, And an angle θ is formed between the first axis L1 and the second axis L2. In this embodiment, the angle θ is between 45 degrees and 90 degrees.

Referring to Figures 2, 4, and 6, the user needs to operate the mobile module 24 to make the tension wheel 5 at the installation position (see Figure 6) when using it. 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 mobile module 24 to make the tension wheel 5 in the working position (see Figure 4), so that the drive shaft 3, the first driven shaft 41, the tension wheel 5, and the second driven shaft 42 and the third driven shaft 43 force the inner peripheral surface 11 of the running belt 1, and then operate the driving unit 6 to drive the driving shaft 3 to rotate to 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 peripheral surface 11 of the running belt 1 through the nozzles 72, and the oiling operation of the running belt 1 can be completed. After the oiling operation is completed, the running belt 1 can be easily removed by operating the tension wheel 5 at the installation position (see FIG. 6 ).

Referring to Figures 2, 5, and 7, during the aforementioned oiling process, sometimes the running belt 1 may have different inner circumferences on the two opposite sides along the third axis Y due to manufacturing tolerances or other factors. Before operating the drive unit 6 to drive the running belt 1 to run, one of the holding parts 281 can be rotated to drive the threaded part 282 to rotate. Since the limiting parts 283 are fixed on the threaded part 282 and are respectively located A plate portion 263 is along two opposite sides of the second axis X, so that the threaded portion 282 can only rotate relative to the respective first plate portion 263 and cannot move along the second axis X, while the threaded portion 282 rotates, the side of the pivot 27 adjacent to the threaded portion 282 will move relative to the seat 26 along the second axis X due to the engagement between the respective lock holes 272 and the threaded portion 282 Move, and then make the first driven shaft 41 sleeved outside the pivot 27 tilt to conform to the inner circumference of the running belt 1 . For example, by operating the adjustment members 28 to move the first driven shaft 41 to the position of the imaginary line in FIG. use. Similarly, when the left inner circumference of the running belt 1 is relatively short, the adjustment members 28 can also be operated so that the left end of the first driven shaft 41 in FIG. 7 is 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 forcing force, so that the driving unit 6 drives the running belt 1 to run more smoothly.

In addition, since the guide piece 713 of the oiling unit 7 can drive the nozzles 72 to move relative to the guide plates 711 along the second axis X, after adjusting the adjustment pieces 28 according to the above steps, It is also possible to adjust the guide 713 to move the nozzles 72 to a suitable position before spraying the lubricating oil (for example: move the nozzles 72 to the position shown by the imaginary line in Figure 7), so that the lubricating oil can be more uniform distributed on the inner peripheral 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 pulley 5, the second driven shaft 42 and the third driven shaft. shaft 43, but in other implementations, 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 tension wheel 5 can force the running belt 1 and define the working space 800 for the oiling unit 7 to achieve the same effect.

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