Embodiment

[0024] A flange taper sleeve for a helicopter reducer includes an inner taper sleeve and an outer taper sleeve. The thickness of the inner taper sleeve and the outer taper sleeve are both 4.35±0.05mm, the taper is 81°, and the outer taper sleeve is located outside the inner taper sleeve. When in use, the distance between the inner and outer shaft sleeves perpendicular to the tapered surface is 4.35mm. On this basis, the maximum distance that the outer tapered sleeve can move axially to the left is 5.36mm. The processing process includes the following steps:

[0025] 1. According to the maximum displacement distance of the outer taper sleeve 1, calculate the maximum width value of the annular chute 3: 5.36×Sin(81° / 2)+4.35=7.832mm

[0026] 2. Rough machining: the forging is processed, and the other positions except the annular chute are processed to the required size, and the position of the annular chute is processed. The thickness after processing is the thickness of the outer ...

Abstract

The invention relates to a machining method of a flange plate taper sleeve. A blank is machined into two parts through the machining method, and the problem that an inner ring taper sleeve body and an outer ring taper sleeve body of a taper sleeve cannot be assembled is solved. By the adoption of the feature that the parts can be moved after being cut off and separated, the machining interference problem caused by narrow ring chutes is solved. By the adoption of the machining method, the machining purpose of the flange plate taper sleeve is achieved, qualified products are machined, and meanwhile a new process method is provided for machining the same kind of parts.

Description

technical field [0001] The invention relates to a processing method, in particular to a processing method of a flange taper sleeve, which solves the processing problem of processing two assembled inner and outer taper sleeves on the same forging. Background technique [0002] The flange taper sleeve of the helicopter reducer is an assembly assembly consisting of two inseparable outer ring taper sleeves 1 and inner ring taper sleeve 2, such as figure 1 shown. The two taper sleeves of this component cannot be assembled after processing. Consider casting or welding to form two inseparable components of the inner and outer ring taper sleeves. However, the material of the part is forged aluminum 2A12. According to the performance requirements, this part is not suitable for casting or welding, etc. processing methods. Therefore, only the method of mechanical processing can be used to process two inner and outer ring taper sleeves on the same forging to ensure the assembly requir...
