Technical Field

[0001] The invention relates to the technical field of gear oiling, and in particular to a gear oiling device. Background Art

[0002] In the prior art, gear oiling is mostly achieved by spraying or manual application. Manual application is inefficient, and the spraying method easily causes waste of oil. Moreover, after spraying, there is too much oil on the surface of the gear, which is easy to drip everywhere, resulting in serious waste of oil. For this reason, Chinese Patent Publication No. CN117943225A discloses an automatic oiling system for gear teeth, which solves the problem of oil waste by recycling the oil. However, this type of suspension conveying method is only suitable for small-sized gears, and is not applicable to large-sized gears, especially those with heavier weight. And considering that the stress environment of large-sized gears is more complex, the requirements for the uniformity of the application are also higher, so it is necessary to design an oiling device for large-sized gears.

[0032] The support assembly 1 has two and is symmetrically arranged on both sides of the end surface of the gear 200 to be oiled. The tooth surface oiling assembly 2 is installed at the end of the floating rod 12 in the two support assemblies 1 and is used to spray oil to the tooth surface of the gear 200 to be oiled; the support assembly 1 includes a support plate 10, an arm body 11, a floating rod 12 and a reset mechanism 13. The four arm bodies 11 are fixed to the outer periphery of the support plate 10 and are arranged at equal intervals. A guide groove 120 is arranged in the arm body 11, and one end of the floating rod 12 is slidably connected to the guide groove 120;

[0033] The reset mechanism 13 is installed on the arm 11 and the floating rod 12 at a side away from the gear 200 to be oiled and is used for resetting the floating rod 12 .

[0034] The support plate 10 on the side close to the power output mechanism 5 is provided with a through hole for the expansion shaft 4 to pass through, and the expansion shaft 4 is connected to the power output mechanism 5 by means of a coupling. In addition, in order to facilitate the floating rod 12 on the side away from the power output mechanism 5 to accurately align with the oiling pipe 20, a guide column 101 that matches the assembly hole of the gear 200 to be oiled is provided on the inner side of the support plate 10 on the side away from the power output mechanism 5.

[0035] The end face oiling assembly 3 is installed on the side of the floating rod 12 and is used to apply oil to the end face of the gear 200 .

[0036] The expansion shaft 4 is installed at the output end of the power output mechanism 5 and can clamp and fix the gear 200 to be oiled. The power output mechanism 5 can output power to drive the gear 200 to be oiled to rotate. The power output mechanism 5 is also connected and fixed to one of the support components 1 through the support member 7. The power output mechanism 5 adopts a servo motor.

[0037] The translation assembly 6 is connected to another support assembly 1 and is used to drive the support assembly 1 to move in the horizontal direction.

[0038] In this embodiment, the gear surface oiling assembly 2 includes an oiling pipe 20 and an oil inlet pipe 21. One end of the oiling pipe 20 is closed and the other end is open. The open end is connected to the oil inlet pipe 21 through a bearing arranged in the oiling pipe 20. A seal is also installed at the bearing in the oiling pipe 20 (for preventing the oil in the oiling pipe 20 from leaking from the bearing). The side wall (i.e., the pipe wall) of the oiling pipe 20 is provided with a plurality of oil injection holes. The oil inlet pipe 21 can be externally connected to a soft oil pipe. The oil entering through the oil inlet pipe 21 will be filled into the oiling pipe 20, and then sprayed out through the oil injection holes to be evenly applied to the tooth surface.

[0039] The floating rod 12 is provided with a mounting hole 121 for mounting the oiling tube 20. One end of the oiling tube 20 is rotatably connected to the mounting hole 121 of the floating rod 12 located on one side of the power output mechanism 5 by means of a bearing.

[0040] A sleeve 14 is installed in the mounting hole 121 of the floating rod 12 on the side away from the power output mechanism 5. The other end of the oiling tube 20 can slide and rotate in the sleeve 14. A chamfer is provided on the side of the sleeve 14 facing the power output mechanism 5 so that the oiling tube 20 can be quickly aligned and entered.

[0041] In this embodiment, the reset mechanism 13 includes a support 130, a support 131, a pull rod 132 and a reset spring 133. The support 130 and the support 131 are respectively installed on the sides of the floating rod 12 and the arm body 11. The upper end of the pull rod 132 is fixed on the support 130, and the other end of the pull rod 132 passes through the support 131 and is connected to the thrust plate 134. The reset spring 133 is sleeved on the pull rod 132 between the thrust plate 134 and the support 131.

[0042] In this embodiment, the end face oiling assembly 3 includes an oiling box 30, an oiling pad 31 and a side support 32. The oiling box 30 is a hollow shell structure. The oiling pad 31 is installed on the inner side of the oiling box 30 and is provided with a plurality of oil drain holes on the inner side of the oiling box 30. The oiling pad 31 is made of a soft material that can be soaked, such as a sponge. An oil supply pipe 33 for supplying oil to the oiling box 30 is provided on the side of the oiling box 30. The outer side of the oiling box 30 is connected to the floating rod 12 by means of the side support 32. In order to ensure that the side support 32 has enough up and down movement distance, a notch groove 122 corresponding to the guide groove 120 is provided on the inner side of the arm body 11, and the side support 32 can slide in the notch groove 122. Example 2

[0043] Based on Example 1, the translation assembly 6 includes a column 60, a base 61 and a slide rail 62. The column 60 is slidably connected to the slide rail 62 by means of a slider at its bottom. The slide rail 62 is installed on the base 61. A vertical plate 63 is installed on each of the bases 61 on both sides of the support seat 60. A rotatable screw 64 is installed between the two vertical plates 63, and one end of the screw 64 is connected to the motor 65.

[0044] The working process and principle of the present invention are as follows:

[0045] In the initial state, the support assembly 1 connected to the translation assembly 6 is away from the other support assembly 1. Then, the gear 200 to be oiled is mounted on the expansion shaft 4 by a manipulator, and the expansion shaft 4 is started to clamp the fixed gear 200. At this time, the oiling tube 20 is located at the tooth root of the gear 200 to be oiled. At this time, the motor 65 is started to drive the lead screw 64 to rotate, and the support assembly 1 connected to the translation assembly 6 is slowly moved toward the gear 200 until the sleeve 14 on the floating rod 12 is connected to the oiling tube 20 (if there is a deviation, it can be adjusted manually). The position of the floating rod 12 is adjusted); after all are aligned, the power output mechanism 5 is started and the gear 200 is driven to rotate. The oiling pipe 20 moves up and down at the tooth surface under the action of the reset mechanism 13, and oil is supplied to the oil inlet pipe 21 and the oil supply pipe 33 simultaneously. The oil sprayed from the oiling pipe 20 is applied to the tooth surface, and the oil sprayed from the oiling box 30 is applied to the end surface of the gear 200. In this way, the tooth surface can be oiled and the end surface of the gear 200 can be evenly oiled by means of the up and down movement of the floating rod 12.

[0046] In the above process, after the gear 200 rotates one circle, it is reversed one circle to achieve a more uniform oiling effect.

[0047] Based on the above, the present invention adopts a floating support component 1 in conjunction with an oiling tube 20 to achieve oiling treatment of the tooth surface of a large-size gear 200, thereby improving the uniformity of the coating and the efficiency of the oiling; the present invention also provides an end face oiling component 3 connected to the floating rod 12, which can achieve oiling treatment of the end face of the gear 200 by means of the up and down movement of the floating rod 12, without the need for subsequent separate oiling of the end face of the gear 200, thereby further improving the oiling efficiency.

[0048] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
