Abstract

The invention discloses a bearing gland nut tightening process device and method, and belongs to the technical field of aero-engine assembly. The bearing gland nut tightening process device comprises a base, a process stand column, a process baffle and a process wrench, wherein the process stand column is fixedly arranged above the base, the process baffle is detachably arranged at the top of the process stand column, and the process wrench penetrates through the process baffle to be connected with a gland nut in a clamped mode. The bearing gland nut tightening process method comprises the steps that a high-pressure turbine unit body is placed on the base, the process baffle is connected with the process stand column, the process wrench is connected with the gland nut in a clamped mode, the process wrench is connected with a torque amplifier, then the torque amplifier is connected with the torque wrench, and the gland nut is tightened through the torque wrench, the torque amplifier and the process wrench. According to the bearing gland nut tightening process device and method, the assembly efficiency of an engine is improved, and the assembly period is shortened.

Description

Technical field [0001] The present invention relates to a technical field of aviation engine assembly, particularly to a process of tightening the gland nut bearing apparatus and method. Background technique [0002] Currently, the fulcrum of the engine 4 when a certain type of bearing inner ring assembly, the assembly process using the core machine state tighten the compression nut that can be conducted within the pivot bearing 4 in the high-pressure turbine and the high-voltage unit body member connected to the rotor unit pivot ring assembly and the inner bearing ring 4, compression nut assembly. When the compression nut assembly, in order to positively lock tab slot nuts, nut needs grinding, and the nut assembly is a serial process, other engine parts can not be assembled during grinding, affect the assembly efficiency. Thus, an urgent need to change the assembly process such that the fulcrum bearing inner ring 4 pressing tighten the nut with the other parts of the engine asse...
