Problems solved by technology
[0005] Face gears have different tooth profiles in the tooth length direction and different tooth widths at different tooth heights on the shaft section. As a result, the three measurement methods used in spur gear processing are not practical here. Bevel gears Although the measurement method of the large-end normal chord tooth thickness can be applied to face gears, the measurement method itself has the disadvantage of different structures when different operators measure the same gear at different times. In addition, the vernier thickness caliper measurement The thick method is often used for the measurement of gears with large modulus. Using this method for gears with small modulus will cause large deviations and require high operator skills.

Embodiment Construction
[0026] The present invention will be further described below in conjunction with the drawings and specific embodiments.
[0027] The present invention is illustrated by taking the following gears as an example:
[0028] The number of teeth of the face gear is 160, the inner and outer radii of the face gear are 80mm and 85mm respectively; the number of teeth of the pinion meshing with the face gear is 24, the modulus is 1.0583, the pressure angle is 20°, and the thickness of the dividing arc is The installation distance between the pinion gear and the face gear is 17.11mm, and the shaft angle is 90°.
[0029] The overall structure of the face gear measuring tool of the present invention is as figure 1 As shown, the measuring tool includes a gear shaft 1, a dial indicator 2, a bushing 3, an alignment part 4, and a screw 6 (5 of which is a face gear sample). Physical image figure 2 Shown.
[0030] The use process of this measuring tool is as follows: first press the bushing 3 into the ...

The invention relates to a face-gear processing measure. Aiming at the problem that no face-gear processing measure exists inland, a measure facilitating operators to ensure process allowance of the face-gear is designed. The measure has characteristics of easy operation, convenient use, rapid and accurate determination of the desired process allowance, simple manufacture, and low manufacture cost. The face-gear processing measure of the invention includes: a gear shaft 1, a dial indicator 2, a bush 3, a benchmarking member 4 and a bolt 5 ( wherein 5 is a face-gear sample).
Description
Technical field [0001] The invention relates to a novel gear-face gear processing measuring tool. Background technique [0002] At present, foreign technical data show that face gears can be processed by gear shaping, gear hobbing and gear grinding, but the design of measuring tools in the processing process has never been mentioned; domestically, since the opposite gear is still in the theoretical research stage, The machining of face gears is still in the stage of rough machining of face gears on ordinary gear shapers. However, when the accuracy of face gears is high, the degree to which the face gears are qualified is a difficult problem for the processors. . [0003] For the processing of spur gears, because the characteristics of the involute tooth profile of the spur gear are the same as the tooth profile in the tooth length direction, three measuring methods are usually used: (1) The thickness of the ruler is measured by a vernier thickness caliper. The advantage of this me...
