Problems solved by technology

However, the cost increase of this method is significant due to the difficulty of disassembly and assembly of the actual parts
[0007] To sum up, due to the lack of accurate calculation methods, the existing technology has a high cost when solving the assembly problem of high-precision coaxial parts that are difficult to be completely interchanged

Embodiment Construction

[0068] The following are specific embodiments of the present invention, and the solutions of the present invention will be further described with reference to the accompanying drawings, but the present invention is not limited to these embodiments.

[0069] The fast calculation method for the installation clearance of two shafts consists of the following four steps (unit: mm, radian):

[0070] Step 1, get the measurement point.

[0071] The stepped shaft is composed of a thin shaft and a thick shaft, and a transition shaft is connected between the thin shaft and the thick shaft.

[0072] The nominal diameter of the thin shaft is 20 and the nominal length is 30; the nominal diameter of the transition shaft is 16 and the nominal length is 10; the nominal diameter of the thick shaft is 30 and the nominal length is 50.

[0073] The nominal diameter 30 of the thick shaft is greater than or equal to the nominal diameter 20 of the thin shaft; the nominal diameter 16 of the transitio...

Abstract

The invention relates to the field of computer aided measurement, and specifically relates to a method for quickly calculating a mounting clearance of two segments of shafts. The method consists of the following four steps: step 1, obtaining geometric design parameters and measurement points; step 2, figuring out fitting diameters and fitting orientations of various segments of holes and shafts; step 3, removing parts with assembly difficulty in advance according to the diameter differences of the holes and shafts; and step 4, solving a minimum comprehensive clearance between the holes and shafts according to step 4.1 and step 4.2.

Description

technical field [0001] The invention relates to the field of computer-aided measurement, in particular to a method for quickly calculating the installation gap of two-section shafts based on mathematical calculation. Background technique [0002] The stepped shaft and its mounting holes are widely used in the mechanical field. At present, the hole-shaft matching parts mainly control the minimum clearance (reflecting the assemblability) and the maximum clearance (reflecting the assembly ability) of the hole-shaft fitting by controlling the dimensional tolerance of each section of hole and shaft, and the coaxiality tolerance between the hole and shaft on the same part. accuracy). [0003] If the dimensional tolerance and geometric tolerance of the design are appropriate, and the dimensional and geometric errors of the parts are in line with the design tolerances, then the assemblability and assembly accuracy of the parts can be guaranteed. At this point, parts are fully inte...
