Embodiment Construction
[0034] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in various ways defined and covered below.
[0035] Such as Figure 1 to Figure 3 As shown, the preferred embodiment of the present invention provides a kind of installation method of driven bevel gear of engine, comprises the following steps:
[0036] Step S1: heat the bearing 11 and install it on the driven bevel gear 12 to form the driven bevel gear assembly 10;
[0037] Step S2: Install the driven bevel gear assembly 10 from the large end of the intake casing 7 into its side hole, and then put the pressure sleeve 6 into the side hole of the intake casing 7 and set it on the driven cone The gear shaft of the gear assembly 10 is horizontally supported on the gear shaft;
[0038] Step S3: insert one end of the pressing block 5 horizontally into the positioning rod 3 and horizontally slide and cooperate wi...

The invention discloses a method for installing an engine driven bevel gear. The installation method of the engine driven bevel gear of the present invention drives the steel ball to move to the left through the push rod, thereby pushing the pressing block to move to the left, and then pushing the driven bevel gear assembly to move to the left to the right position, and using the pressure sleeve to press the driven cone The gear assembly is horizontally supported to ensure that the driven bevel gear assembly remains horizontal during movement, and then the driven bevel gear assembly is accurately assembled into the intake case using static pressure, and the stop washer is used to resist the bearing The inner ring prevents the bearing from shifting during the process of bolt locking the bearing, ensuring the accuracy of the assembly, thereby realizing the precise assembly of the driven bevel gear in place, and there will be no position deviation, which can be well adapted to the space Assembly scenes with small, untappable parts, and the entire assembly process is visible.
Description
technical field [0001] The invention relates to the technical field of engine assembly, in particular to an installation method of an engine driven bevel gear. Background technique [0002] The driven bevel gear of an aeroengine is an important transmission structure of the engine. Only when the driving bevel gear meshes well with the driven bevel gear can the engine speed change normally without causing vibration and wear. Among them, the driven bevel gear is fixed on the casing through bearings, and the driven bevel gear and the bearing have an interference fit, and the spring support of the bearing and the casing has an interference fit. How to ensure that the driven bevel gear and the bearing, the bearing and the machine When the bullets of the magazine are assembled in place, it has a great influence on the normal meshing of the driving bevel gear and the driven bevel gear. [0003] However, the current installation method of the driven bevel gear of the engine cannot ...
