Detailed Description

Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings and the description to refer to the same or like parts.

Fig. 1 is a schematic view of an oil feeding device according to an embodiment of the present invention. Referring to fig. 1, an oil feeding device 1 of the present embodiment is used for applying lubricating oil to a gear 2, and the oil feeding device 1 includes a box 11 and a switch 12.

The case 11 has an oil inlet opening 111, an oil outlet opening 112, and an oil passage 113 connected between the oil inlet opening 111 and the oil outlet opening 112. The oil inlet opening 111 of the present embodiment is located at the bottom of the tank 11, and the oil outlet opening 112 is located at the top of the tank 11. The oil inlet opening 111 is connected to an oil pipe (not shown) that supplies lubricating oil, wherein the lubricating oil enters from the oil pipe through the oil inlet opening 111 and is stored in the oil passage 113. In one embodiment, the oil inlet opening 111 may be sealed via a sealing cover (not shown), and in case that the lubricating oil stored in the oil passage 113 is insufficient, the sealing cover is removed to fill the lubricating oil from the oil inlet opening 111 into the oil passage 113. In the present embodiment, the oil inlet opening 111 is located at the bottom of the box 11 for illustration, but the invention is not limited thereto, and the oil inlet opening 111 may also be located at the side of the box 11 or at the top of the box 11 as the oil outlet opening 112, and is determined according to the actual requirement.

The switch 12 is movably disposed through the oil outlet 112, and the switch 12 normally closes the oil outlet 112. That is, in the initial state of the oil feeding device 1, the lubricating oil stored in the oil passage 113 cannot overflow the oil outlet opening 112.

In view of the above, the switch 12 has a first portion 121 and a second portion 122 connected to the first portion 121, wherein the first portion 121 has a first outer diameter D1, and the second portion 122 has a second outer diameter D2, the first outer diameter D1 being equal to the inner diameter D3 of the oil outlet opening 112. When the switch 12 is in the first position, the first portion 121 closes the oil outlet opening 112. The second outer diameter D2 is greater than the first outer diameter D1.

Furthermore, the oil feeding device 1 further includes a spring 13 disposed between the case 11 and the switch 12, wherein one end of the spring 13 is connected to the case 11, and the other end of the spring 13 is connected to the switch 12. The spring 13 provides a spring force to the switch 12 to normally position the switch 12 in the first position to close the oil outlet opening 112.

As shown in fig. 1, in a normal state, i.e., an initial state of the oil feeding device 1, the spring 13 provides an elastic force to the switch 12 to maintain the switch 12 at the first position where the first portion 121 of the switch 12 is received in the oil outlet opening 112 and closes the oil outlet opening 112.

Fig. 2 is a schematic view of placing a gear on the switch 12 and applying a force to the gear to move the switch 12 to a second position, fig. 3A is a perspective view of fig. 2, and fig. 3B is a top view of fig. 3A. Referring to fig. 2, fig. 3A and fig. 3B, when the oil feeding device 1 is used to oil the gear 2, the gear 2 is placed on the switch 12, wherein the diameter (not labeled) of the addendum circle of the gear 2 is equal to the first outer diameter D1. Then, when the gear 2 is pressed by force to drive the switch 12 to move to the second position relative to the box body 11, the first part 121 of the switch 12 is withdrawn out of the oil outlet opening 112 to open the oil outlet opening 112, and the lubricating oil stored in the oil path 113 flows into the tooth gaps of the gear 2 through the oil outlet opening 112 and contacts and is attached to the gear 2, so that the gear 2 is evenly coated with the lubricating oil.

Incidentally, the lubricating oil may be one that flows into the tooth gaps of the gear 2 by capillary action and is attached to the gear 2; alternatively, it is also possible to additionally provide a cylinder (not shown) with which the lubricating oil is pushed from the oil passage 113 to the oil outlet opening 112 to flow into the tooth gaps of the gear 2 to be attached to the gear 2, and also to adjust the height at which the lubricating oil wets the gear 2 by the cylinder (not shown).

It should be noted that, since the diameter (not labeled) of the addendum circle of the gear 2 is equal to the first outer diameter D1 and equal to the inner diameter D3 of the oil outlet opening 112, the amount of the lubricant overflowing can be controlled by the depth of the gear 2 penetrating into the oil outlet opening 112 via the magnitude of the force applied, so as to prevent the lubricant from overflowing from the oil path 113 to the oil outlet opening 112 excessively.

Further, since the switch 12 is normally located at the first position to close the oil outlet opening 112, the lubricating oil can be prevented from being contaminated. Fig. 4 is a schematic view of an oil feeding device according to another embodiment of the present invention. Referring to fig. 4, in another embodiment, the oil feeding device 1' further includes a sleeve 4 detachably disposed on the switch 12. The inner diameter D4 of the sleeve 4 is smaller than the first outer diameter D1, i.e. the inner diameter D4 of the sleeve 4 is smaller than the inner diameter D3 of the oil outlet opening 112.

The other arrangements of the case 11, the oil inlet 111, the oil outlet 112, and the oil passage 113 of the case 11, the switch 12, the first and

second portions

121 and 122 of the switch 12, and the spring 13 are the same as those of the embodiment shown in fig. 1, and therefore, the description thereof will not be repeated.

Fig. 5 is a schematic illustration of oiling a gear using the oil feed apparatus of fig. 4. Referring to fig. 4 and 5, substantially the same as the previous embodiment, the gear 2 'is placed in the sleeve 4, the gear 2' abuts against the inner side of the sleeve 4, and the switch 12 is driven by pressing the gear 2 'to move to the second position, so that the lubricating oil can flow from the oil path 113 through the upper surface of the switch 12 and into the tooth gaps of the gear 2' to wet the local part of the gear 2 ', so as to oil the gear 2'.

The difference from the previous embodiment is: the diameter of the addendum circle of the gear 2' of the present embodiment is equal to the inner diameter of the sleeve 4; that is, the diameter of the addendum circle of the gear 2' of the present embodiment is smaller than that of the gear 2 of the embodiment of fig. 2.

As can be seen from the above, by applying the sleeves having different inner diameters, the oil feeding device can be applied to gears having different diameters of addendum circles.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
