Method for measuring inverted conical tooth lateral cone angle of gear wheel

Abstract

The invention discloses a method for measuring an inverted conical tooth lateral cone angle of a gear wheel. The method is characterized in that an employed cylinder coordinate measuring machine consists of a measuring head, a rotary shaft and three linear axes including an X axis, a Y axis, and a Z axis. The measuring head has a conical structure with a shape-corrected top and is capable of detecting a straight conical tooth and an oblique conical tooth precisely; a computer obtains precise detection data of a tooth lateral cone angle directly to provide an accurate and reliable detection report. Therefore, a blank of precise detection of a lateral cone angle of the 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 taper angle of a reverse bevel tooth side of a gear. 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 direct meas...

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, according to the scale processing on the equipment, it is impossible to provide accurate inspection data. Since the top of the tooth is formed by the intersection of circular arc surfaces, it is impossible to accurately measure the width of the upper and lower tooth tops. It causes a lot of errors. Since the tooth surface is a curved surface, it is impossible to establish a plane by simply and accurately measuring the arc surface on the three-coordinate instrument, and the obtained data is not accurate. It is difficult to accurately measure the actual pitch angle of the spur bevel gear. The angle will directly affect the interchangeability of gears, and there are deficiencies, which cannot meet the needs of rapid social development.
