Description

One-shaft oil collecting ring and one-shaft lubricating system

Technical Field

The utility model belongs to the technical field of speed changers, and particularly relates to a shaft oil collecting ring and a shaft lubricating system.

Background

To reduce driver effort, most mechanical transmissions employ synchronizers to shift gears to reduce shifting forces. In the past, a sliding sleeve type gear-shifting double-intermediate-shaft transmission which is in gear shifting and achieves uniform load through two-shaft hinged floating is adopted, and in recent years, the sliding sleeve gear shifting is replaced by the synchronizer gear shifting basically. The front end of the two shafts of the old structure can not meet the working requirement of the synchronizer gear shifting in the transmission by providing support in the shaft hole of the first shaft through the oil-containing shaft sleeve with radial clearance with the two shafts. In order to improve gear shifting smoothness, the floating of the two shafts is reduced, the main box synchronizer is protected, and the front ends of the two shafts are supported by the shaft sleeve in the inner cavity of the rear end of the first shaft instead of being supported by the bearing. At present, a bearing support is adopted between a first shaft and a second shaft head of a single-intermediate shaft transmission or a double-intermediate shaft transmission, and burn damage of the second shaft front support bearing caused by poor lubrication at the position is one of the biggest faults in after-sale service of a mechanical transmission.

Patent publication No. CN113738827a, entitled oil collecting ring and planetary gear mechanism, in which a boss portion of the oil collecting ring is fixed to a main body portion and protrudes radially outward at least partially from an outer peripheral wall of the main body portion, the boss portion is formed with an opening located radially outward of the outer peripheral wall and opening toward both sides in a circumferential direction of an oil discharge plate, and the boss portion is further formed with an oil inlet passage extending from the opening to the oil discharge plate. The oil drain plate of the oil collecting ring is fixed to the main body portion, extends from the main body portion toward one side in the axial direction, and is formed with an oil drain passage communicating with the oil intake passage. The application can utilize the effect of centrifugal force, collects the lubricating oil on the surface of the peripheral wall of the main body part through the opening of the protruding part, but the protruding part of the application can not be closely attached to a shaft, and the protruding part can collect the lubricating oil through the oil inlet channel, the opening size is limited, the collection amount is smaller, and a shaft is required to have higher centrifugal force.
