Method for measuring alignment degree of internal keyway and tooth part of gear wheel

Abstract

The invention discloses a method for measuring an alignment degree of an internal keyway and a tooth part of a gear wheel. A central spindle of a gear wheel is installed at a gear wheel measuring center instrument; relevant parameter values are inputted at a display window of the measuring center instrument; detection is carried out by a measuring head arranged at the top of the measuring center instrument; and a detection result is transmitted to the surface of the display window directly. A telescopic guide post is installed in the middle of the measuring head. An internal keyway and a tooth part of a gear wheel are detected automatically and a precise and reliable detection report is obtained by a computer directly. Therefore, a blank of precise detection of an alignment degree of a gear wheel can be filled. The method can be used conveniently. And the method based on a novel design is a novel method and thus has the broad market promotion prospects.

Description

technical field [0001] The invention relates to the field of mechanical production, in particular to a method for measuring the alignment degree of a keyway in a gear and a tooth portion. Background technique [0002] Bevel gears are widely used in machine tools, automobiles, mines, construction and other mechanical equipment. Straight-toothed bevel gear is an important part of the grinding machine. The accuracy of its pitch cone angle directly affects the noise, strength, contact area of ​​the tooth surface and the stability of the gear transmission when the gear is meshing. It is an important parameter that affects the quality of the gear. . Therefore, the accuracy of pitch angle measurement of spur bevel gear directly affects the processing quality of the gear. However, the pitch cone angle of straight bevel gears is the contact cone angle produced when a bevel gear meshes with another bevel gear with only pure rolling but no sliding. It is a spatial angle, and the dire...

Problems solved by technology

However, the pitch cone angle of straight bevel gears is the contact cone angle produced when a bevel gear meshes with another bevel gear with only pure rolling but no sliding. It is a spatial angle, and the direct measurement and detection of its angle has always troubled engineering technology personnel

[0003] At present, since the tooth surface is a curved surface, it is impossible to simply and accurately measure the curved surface on a three-coordinate instrument to establish a plane, and the obtained data is not accurate, resulting in relatively large errors in processed products, which cannot meet the needs of rapid social development.
