Intermediate shaft spiral gear meshing position degree gauge

Abstract

The invention relates to an intermediate shaft spiral gear meshing position degree gauge. The intermediate shaft spiral gear meshing position degree gauge includes an auxiliary measurement device anda base; two support blocks for supporting an intermediate shaft are fixed to the base and are located at the two shaft ends of the intermediate shaft respectively to locate the shaft end excircles andend faces of the intermediate shaft, a support is fixed to the portion, located at the side of the intermediate shaft, of the base, and a first bolt for locating a first gear on the intermediate shaft and a second bolt for locating a second gear on the intermediate shaft are mounted on the support; the auxiliary measurement device is fixed to the intermediate shaft, rotates along with rotation ofthe intermediate shaft and is provided with a scale line marking face extending in the radial direction of the intermediate shaft. The intermediate shaft spiral gear meshing position degree gauge candirectly detect the position degree at a production site during machining, the procedure and quality are convenient to control, and unnecessary carrying links can also be omitted.

Description

technical field [0001] The invention relates to a checking tool, in particular to a checking tool for the position degree of the helical teeth of an intermediate shaft. Background technique [0002] A new product transmission developed by the applicant company, the assembly adopts such as figure 1 and figure 2 In the double helical intermediate shaft structure shown, the parameters of the first tooth are the modulus m1, the number of teeth z1, the pressure angle α1, and the helix angle β1, and the parameters of the second tooth are the modulus m2, the number of teeth z2, the pressure angle α2, The helix angle β2 is left-handed, the distance of the first pitch from the reference end face C is the distance L1 from the section P-P to the reference end face C, the distance from the second pitch from the reference end face C is the distance L2 from the section S-S to the reference end face C, the two teeth of the section P-P and the section S-S The center position of the groov...

Problems solved by technology

[0003] In the process of double-tooth intermediate shaft processing, the gear hobbing and gear grinding processes need to carry out position detection. The company's original processing method needs to unload the product from the processing equipment and then move it when the position detection of the gear hobbing and gear grinding processes Using a proprietary program to measure on the comprehensive gear measuring instrument, the position detection cannot be carried out directly on the processing site. The measurement process is time-consuming and laborious. If the measured product is oversized and overweight, it is easy to damage the comprehensive gear measuring instrument.
