Abstract

The invention discloses a cold-start high-pressure driving tool for an aircraft engine. The tool comprises a rotating shaft, an input shaft, a connecting rod, a connecting bushing and a working bend,wherein the right end of the rotating shaft is sleeved with a handle, the left end of the rotating shaft is mounted on a planetary reducer, the input shaft is mounted at the left end of the planetaryreducer, the left end of the input shaft is fixedly connected with the connecting rod, the left end of the connecting rod is mounted on the connecting bushing, and the working bend is arranged at theleft end of the connecting bushing; the outer side of the middle of the connecting rod is matched with the upper end of a fixing seat through a bearing, and the lower end of the fixing seat is fixed on a rack through a clamping mechanism; a driving rod is mounted in the connecting bushing through a bearing and fixedly connected with the left end of the connecting rod, and the left end of the driving rod extends into the working bend; the working bend is L-shaped, a bevel gear set is arranged in the working bend, and a switching sleeve is also arranged in the working bend. The cold-start high-pressure driving tool has the benefits as follows: the tool is simple to operate, rapid to start and convenient to maintain and the workload is reduced.

Description

technical field [0001] The invention relates to the technical field of aero-engine drive and maintenance, in particular to an aero-engine cold-start high-voltage drive tool. Background technique [0002] At present, when the engine is installed and needs to be cold started, it is usually completed by ignition of the turbine starter on the aircraft, and there is no tool specially used for the cold start of the aircraft engine. During the ground maintenance test run, the aircraft skin is usually opened, and a ratchet wrench is used to drive the high-pressure rotor to complete the cold start of the engine. Since the number of ignitions of the turbine starter is strictly regulated, there is a requirement for ignition life. Turbine starters are expensive, and frequent use of turbine starters reduces the working life of turbine starters and greatly reduces the number of times an aircraft can fly. the cost is too high. The method of using the ratchet wrench to realize the cold s...
