Abstract

The invention discloses a clamping and positioning device used for disassembling and assembling an airplane pneumatic starter rotor and a rotor disassembling and assembling method. The clamping and positioning device comprises a fixed supporting ring and at least two sets of pawl installing and fixing assemblies, wherein each pawl installing and fixing assembly is composed of a pawl installing and supporting screw, a gear fixing pawl and a rotating installation handle, the pawl installing and supporting screws are inserted into the fixed supporting ring and connected with the fixed supporting ring in a spiral threaded mode, each gear fixing pawl is arranged at the inner rod end, located in the fixed supporting ring, of the corresponding pawl installing and supporting screw, a gap is reserved between each gear fixing pawl and the inner rod end of the corresponding pawl installing and supporting screw after the gear fixing pawl is installed, a tooth socket which is matched with a gear of the rotor is arranged on the inner end face of each gear fixing pawl, when the rotor is installed or detached, and the tooth sockets of the gear fixing pawls are used for being meshed with the gear of the rotor so that the circumferential rotation of the gear of the rotor and the circumferential rotation of the rotor can be limited. Meanwhile, the invention discloses the rotor disassembling and assembling method of the clamping and positioning device.

Description

technical field [0001] The invention relates to a positioning tool and a method for disassembling an aircraft component, in particular to a clamping and positioning device for disassembling and disassembling a rotor of an aircraft pneumatic starter and a method for disassembling the rotor. Background technique [0002] The aircraft pneumatic starter is the core component of the aircraft engine starting device. Most of the pneumatic starters use the pneumatic cascade rotor to drive the gear set to adjust the speed and transmit the torque of the output shaft to realize its starting function. [0003] The rotor assembly of the pneumatic starter is the core component of the starter. The installation quality of the rotor assembly directly determines the quality of the starter. The matching structure of the rotor assembly is often complex, requiring high assembly accuracy and narrow assembly space, which is difficult to achieve with ordinary tools. The fixing, supporting and disas...
