[0030] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] The utility model provides a transmission gear seat. When the gear drives the gear shaft to transmit, the gear shaft rotates in a circle. Under the action of centrifugal force, the oil control mechanism is opened to discharge the lubricating oil inside the oil chamber, lubricating the outer walls of both ends of the gear shaft to avoid wear when the gear shaft rotates. Please refer to Figure 1-Figure 6 , including: a supporting component 100, a gear component 200 and an oil control mechanism 300.

[0032] The supporting component 100 includes a gear shaft 110, an oil chamber 120 and a connecting key 130. The oil chamber 120 is arranged inside the gear shaft 110, and the connecting key 130 is arranged on the gear shaft 110.

[0033] The gear shaft 110 is a transmission shaft with thin ends and a thick middle, and the oil chamber 120 is a cavity with a thick inner part and thin ends. Both ends of the oil chamber 120 pass through the gear shaft 110 for lubricating oil to flow.

[0034] The gear member 200 is disposed on the gear shaft 110 ; gear transmission is performed through the gear member 200 .

[0035] The oil control mechanism 300 is disposed at both ends of the oil chamber 120 , and the flow of lubricating oil in the oil chamber 120 is controlled by the oil control mechanism 300 .

[0036] Specifically, a retaining ring 140 is provided on the gear shaft 110, and a first pin hole 150 is formed on the retaining ring 140. The gear component 200 includes a gear 210, a key slot 220 and a second pin hole 230. The key slot 220 connected to the connecting key 130 is provided inside the gear 210. The gear 210 is provided with a second pin hole 230 corresponding to the first pin hole 150. A pin shaft 400 is provided between the first pin hole 150 and the second pin hole 230.

[0037] Among them, the pin shaft 400 adopts a C-shaped pin, the first pin hole 150 and the second pin hole 230 are evenly distributed in a herringbone shape, the gear 210 rotates synchronously with the gear shaft 110 through the connecting key 130, and the pin shaft 400 improves the connection stability between the gears 210 and 210.

[0038] The oil control mechanism 300 includes an end cover 310 and a spring 320. The end cover 310 is connected to both ends of the oil chamber 120. The spring 320 is arranged between the end cover 310 and the oil chamber 120.

[0039] Among them, the lower end of the spring 320 is fixed in the oil chamber 120, and the two ends of the oil chamber 120 are T-shaped channels. The diameter of the end cover 310 is smaller than the inner diameter of the large hole at the upper end of the T-shaped channel, and larger than the inner diameter of the small hole at the lower end of the T-shaped channel. When the spring 320 is in a natural state, the end cover 310 is closed on the small hole at the lower end of the T-shaped channel. When the gear shaft 110 rotates at a high speed, the end cover 310 is driven to swing outward under the action of centrifugal force, so that the end cover 310 is separated from the oil chamber 120. After the speed is reduced, the spring 320 drives the end cover 310 to reset and close the oil chamber 120.

[0040] During specific use, gear transmission is performed through the gear component 200, and the gear 210 rotates synchronously with the gear shaft 110 through the connecting key 130. When the gear shaft 110 rotates at a high speed, the end cover 310 is driven to swing outward under the action of centrifugal force, so that the end cover 310 is separated from the oil chamber 120. At this time, the lubricating oil can flow out from the gap between the end cover 310 and the oil chamber 120 to lubricate the gear shaft 110. After the speed is reduced, the spring 320 drives the end cover 310 to return to its original position to close the oil chamber 120.

[0041] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
