Method for testing error of centralization of herringbone tooth and testing ball

Abstract

The invention relates to a method for testing error of centralization of herringbone tooth and a testing ball. The method is characterized in that a machining line of a right-handed rotation tooth is drawn out on a milling machine and the right-handed rotation tooth is milled out after the finish-milling of the left-handed rotation tooth is completed; the operation steps are as follows: 1), arranging a cylindrical handle of the testing ball on the right-handed rotation end face of the gear, measuring the outer cylindrical surface of the cylindrical handle by using a dial indicator, recording the jump value; 2), taking the testing ball off and arranging on the corresponding right-handed rotation tooth end, measuring the maximum bus position of the cylindrical handle by the dial indicator, and recording the jump value; and 3), obtaining the error of centralization of the left-handed rotation tooth and the right-handed rotation tooth according to the jump values of the dial indicator in the step 1) and the step 2), so as to determine the adjustment direction of the knife-feeding in the next time, and carrying out the finish-milling to the right-handed rotation tooth. Compared with the prior art, the invention has the following beneficial effects: the testing ball is simple in structure, convenient to manufacture, and flexible in service; when the testing ball is used for testing error of centralization of herringbone tooth, the testing ball is convenient to operate and the precision is easy to control; practices prove that the high-precision centralization requirement of the herringbone tooth machining can be met entirely.

Description

technical field [0001] The invention relates to the field of gear machining, in particular to a method for inspecting a centering error of a herringbone tooth and an inspection measuring ball. Background technique [0002] The herringbone gear has a strong bearing capacity, can self-balance the axial force generated during the transmission process, and has the remarkable characteristics of good interaction stability. It is divided into ordinary herringbone gears, helical assembled herringbone gears, and combined herringbone gears in structure. Teeth, etc., are widely used in heavy mining equipment. In order to ensure the accuracy of the human gear in gear machining, the centering of the herringbone intersection of the herringbone gear must first be guaranteed. The traditional processing method is that after milling the left-handed teeth, the scriber draws the processing line of the right-handed teeth on the milling machine and mills out the right-handed teeth. The thicknes...

Problems solved by technology

The traditional processing method is that after milling the left-handed teeth, the scriber draws the processing line of the right-handed teeth on the milling machine and mills out the right-handed teeth. The thickness is 0.2 ~ 0.3mm, which means that the centering accuracy is 0.2 ~ 0.3mm, and the herringbone teeth with high precision requirements will not be able to meet the requirements
