Abstract
The invention provides a rudder support bearing cover. The rudder support bearing cover comprises a cover plate (10), spring washers (20) and an oil injection nozzle (30), wherein four bosses are arranged on the surface, away from a bearing, of the cover plate (10), a step-shaped annular through hole is formed in the cover plate (10) and used for clamping a rudder rotating pipe shaft, an L-shaped channel is formed in each boss, the axial direction of an inlet of each L-shaped channel is parallel to or forms an acute angle with the surface of the cover plate (10), an outlet of each L-shaped channel is formed in the step of the step-shaped annular through hole and used for injecting lubricating grease into a bearing ball of the rudder support bearing, an inlet of the L-shaped channel is in threaded connection with the oil injection nozzle (30), and the spring washers (20) are arranged between the inlet of the L-shaped channels and the oil injection nozzle (30).
Description
technical field [0001] The invention belongs to the technical field of aviation, and in particular relates to a rudder support bearing bearing cap. Background technique [0002] The connecting structure of the empennage rudder bearing block of the large rudder surface rudder of existing aircraft is as follows: figure 1 As shown, see the Chinese patent application number 201610217272.6. [0003] When the bearing is filled with grease in situ on a daily basis, due to the limitation of structural space, the rudder must be hoisted, the bearing support must be removed, and the bearing cover 1 can be opened to implement the grease injection, which is time-consuming and labor-intensive. Contents of the invention [0004] The invention provides a bearing cap of a rudder support bearing, which realizes in-situ injection of grease and facilitates daily lubrication of the rudder support bearing. [0005] The present invention provides a rudder support bearing bearing cover, includi...
