Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical transmission, in particular to a transmission gear seat. Background Art

[0002] During the use of the transmission gear seat, it was found that when the transmission gear works between multiple gears that cooperate with each other, it is easy to generate a large friction force, which easily causes the transmission gear to wear. After searching, the patent with application number 202321136718.4 discloses a transmission gear seat, including a truncated cone with a through hole and a pin hole, a gear fixedly connected to the truncated cone, and a tapered pin. The gear includes a spoke and a gear body. The gear body is arranged on the outside of the spoke to mesh with other gears. The spoke is provided with an oil cavity for storing lubricating oil and a plurality of oil outlet holes. The oil cavity is arranged inside the spoke, and the plurality of oil outlet holes are evenly distributed on the outside of the spoke to penetrate the oil. The structure of the gear seat is improved, and an oil cavity with lubricating oil stored inside is added. In combination with the oil outlet hole, the lubricating oil can seep out during the rotation of the gear body, thereby reducing the wear of the transmission gear during use.

[0003] However, during actual use, the applicant found that it was impossible to control the amount of lubricating oil leakage during use. When the gear rotates at high speed, the oil in the oil chamber will accelerate the leakage from the oil chamber under the action of centrifugal force, causing excessive oil to adhere to the gear, thereby causing a waste of oil. In view of this, we propose a transmission gear seat. Utility Model Content
