Problems solved by technology
[0005] The object of the present invention is to provide an installation assembly for an aero-engine oil pump, to solve the problem that the existing oil pump proposed in the above background technology needs to be connected with the engine before installation and use, and then connect the oil pipeline with the engine. The oil pump is connected, and the installation process is cumbersome. At the same time, it is necessary to use different tools for installation when connecting the oil pump to the engine and when connecting the oil pipeline to the oil pump. Frequent replacement of tools is required during installation, which is troublesome to operate and low in production efficiency.

The invention discloses an oil pump for an aero-engine, and relates to the technical field of aero-engines. The problems that when an existing oil pump is mounted and used, tools need to be replaced frequently, operation is troublesome, and the production efficiency is low are solved. The oil pump comprises an engine body. Two sets of front and rear clamping blocks are slidably connected to the upper end face of the engine body; two sets of locking intermediate shafts are axially connected into the engine body; two sets of locking screws are axially connected into the engine body; the left side and the right side of the top of the engine body are each axially connected with a set of connecting pipe driving shafts; and the interiors of the left side and the right side of the top of the engine body are each axially connected with a set of connecting pipe intermediate shafts. The oil pump is easy to use, convenient to operate, good in positioning effect and stable in connection, fixing ofthe oil pump body and connection of an oil way can be completed only through one tool, mounting is greatly facilitated, the mounting speed is greatly increased, frequent tool replacement is avoided,and the mounting efficiency is greatly improved.
Description
technical field [0001] The invention relates to the technical field of aero-engine matching, in particular to an installation assembly of an aero-engine oil pump. Background technique [0002] All aircraft engines need to be equipped with an oil pump to provide lubricating oil for the engine to ensure the normal operation of the engine. [0003] For example, application number: CN201010552414.7 An eccentrically regulated variable rotor oil pump, which consists of a pump body, a pump cover, an outer rotor, an inner rotor, an eccentric ring with outer teeth, a retaining pin, a rack valve part and a safety valve part. The pump body is provided with a rack valve hole for installing the rack valve part, a safety valve hole for installing the safety valve part and a limit stop pin, the rack valve part is installed in the rack valve hole, and the safety valve part is installed in the safety valve bore. The outer tooth eccentric ring is installed in the outer tooth eccentric ring ...
