Output bearing oil delivery mechanism, intermediate reducer and helicopter

Abstract

The invention discloses an oil delivery mechanism for an output bearing. The lubricating oil is stored in the casing oil pool of the casing. The input shaft of the intermediate reducer of the helicopter meshes and drives the gear to rotate to drive the lubricating oil in the casing oil pool to splash, and the oil collecting device collects the lubricating oil. The lubricating oil splashed with the gears is introduced into the oil guide structure, and the lubricating oil in the oil guide structure guides the lubricating oil to the oil groove of the end cover under the action of the centrifugal force formed by the high-speed rotation of the gear shaft, and then the lubricating oil enters the bearing to clean the bearing Lubricates and returns to the case sump. The components of this application have simple structure, very reliable assembly and good casting process. While rationally utilizing the space, they also play a role in reducing weight; making full use of the centrifugal force brought by the rotation of the output bearing, so that the lubricating oil flows along a specific direction, Good lubricating effect: the oil delivery structure is located inside the output shaft, correspondingly shortening the length of the output gear shaft and reducing the weight of the intermediate reducer. The invention also discloses an intermediate reducer and a helicopter.

Description

technical field [0001] The present invention relates to the technical field of bearing lubrication, in particular, to an output bearing oil feeding mechanism. In addition, the present invention also relates to an intermediate speed reducer and a helicopter comprising the above-mentioned output bearing oil feeding mechanism. Background technique [0002] The angle between the input axis and the output axis of the intermediate reducer of a helicopter is usually an obtuse angle, the output end is upturned, the output bearing position is high, and lubrication is difficult, but the output bearing is the key component of the helicopter intermediate reducer, and its performance is very high. Quality directly affects the service life and reliability of the intermediate reducer, and excellent lubrication design is an important guarantee for improving the service life and reliability of the bearing, and also affects the number of intermediate reducer parts, the weight of the whole mac...
