Surveying and mapping method for hypoid bevel gear of drive axle

Abstract

The invention relates to the technical field of drive axle hypoid bevel gears, and discloses a drive axle hypoid bevel gear surveying and mapping method, which comprises the steps of measuring macroscopic parameters, establishing a macroscopic parameter analysis model, establishing a metering detection model and establishing a microcosmic modification parameter analysis model. According to the surveying and mapping method for the hypoid bevel gear of the drive axle, surveying and mapping of the hypoid bevel gear can be achieved, specifically, firstly, the radius of a cutter head and the radius of a first fillet of a milling cutter are preliminarily selected and then analyzed through Gleason bevel gear design software, and if the analysis result is within the error range, the radius of the cutter head and the radius of the first fillet of the milling cutter are determined; if the difference value of the distance between the detection point and the measurement point in the normal direction is within a fifth range, it is considered that selection of a macroscopic parameter estimation cutter radius and a first fillet radius is reasonable, and then a microscopic modification parameter is estimated according to the actual meshing position of the two hypoid gears and the shape of the contact area; if yes, it is considered that selection of the microscopic modification parameters is reasonable.

Description

technical field [0001] The invention relates to the technical field of hypoid bevel gears of drive axles, in particular to a method for surveying and mapping hypoid bevel gears of drive axles. Background technique [0002] In the parameter mapping of cylindrical gears, the spatial tooth surface shape is relatively simple, and the real design parameters can be obtained relatively easily. However, in the surveying and mapping of drive axle hypoid gears, due to the complex structure of the tooth surface, the pressure angle and machining need to be considered in the mapping. However, the selection of these parameters is relatively difficult. Due to the complexity of the tooth surface of the driving bridge conical hypoid gear, the microscopic parameters cannot be directly measured, which makes the surveying and mapping of the driving bridge hypoid gear more difficult. When there are only hypoid gears but no engineering drawings, it is very complicated to obtain the three-dimensio...

[0002] In the parameter mapping of cylindrical gears, the spatial tooth surface shape is relatively simple, and the real design parameters can be obtained relatively easily. However, in the surveying and mapping of drive axle hypoid gears, due to the complex structure of the tooth surface, the pressure angle and machining need to be considered in the mapping. However, the selection of these parameters is relatively difficult. Due to the complexity of the tooth surface of the driving bridge conical hypoid gear, the microscopic parameters cannot be directly measured, which makes the surveying and mapping of the driving bridge hypoid gear more difficult. When there are only hypoid gears but no engineering drawings, it is very complicated to obtain the three-dimensional data of the hypoid gears through measuring equipment, and establish a parameter benchmarking analysis design model. The existing technology does not disclose how to measure and map the hypoid bevel gears. Methods
