Embodiment 1

[0052] Measured gear parameters

[0053] Z 大 =37, Z 小 =9, interaxial angle δ=90°

[0054] ω 模数 =1.387β 螺旋角 =35° α 齿形角 =20° tooth width B

[0055] Calculate the measuring ball diameter d=φ1.75 (rounded)

[0056] Calculate the installation size: A=22.25, B=14.40

[0057] Gear production adopts this tooth thickness measurement method to control the tooth thickness quality of the processed gear, together with Figure 7 , 8 The three-dimensional digital measurement method of gear teeth is shown to control the quality of gear teeth and combined with traditional contact zone control. The small modulus bevel gear produced by this method can replace the traditional large and small wheel matching production mode. The large and small wheels produced in large quantities can be installed interchangeably and maintain the same meshing quality.

Abstract

The invention provides a device for measuring tooth thickness of a medium and small modulus bevel gear. The device comprises a guide rail, a block gauge A and a block gauge B, wherein a guide rail sliding block I and a guide rail sliding block II, which can move forwards and backwards, are arranged on the guide rail, and are respectively connected with a dial indictor and a measuring worktable; the block gauge A and the block gauge B are matched with a measured gear in dimension; and the tooth thickness of the gear can be measured by lifting the dial indicator and replacing a measuring ball which is connected with the dial indicator; and the dimension of the measuring ball is in match with the tooth thickness of the measured gear. The device is convenient for measurement and high in measurement precision and is efficient and reliable. According to the device, the actual value of the tooth thickness can be obtained by calculating according to diameter data of the block gauge A, the block gauge B and the measuring ball and under the condition that the measuring ball can be replaced. The invention also provides an efficient and reliable measuring method adopting the measuring device. According to the method, a mounting base surface of the measured gear serves as a measuring reference surface, and the measuring method controls the tooth thickness to ensure the consistency between the tooth thickness on the mounting base surface and the mounting distance of the measured gear.

Description

technical field [0001] The invention relates to the technical field of small and medium modulus bevel gear manufacturing. [0002] Background technique [0003] At present, the production of small and medium modulus bevel gears at home and abroad is supplied in pairs. During the production process, the tooth thickness of the large wheel is controlled, the small wheel is matched with the large wheel, and the contact area and meshing gap are adjusted by the rolling inspection machine, and the market is supplied in pairs. In particular, the mass production of small and medium modulus spiral bevel gears is processed by double-sided cutter heads and double-sided methods. In order to effectively improve the processing quality of bevel gears, it is very effective to control the tooth thickness of the bull gear. [0004] The measurement of tooth thickness in the manufacturing process of bevel gears at home and abroad generally adopts the following methods: [0005] 1. Using tooth...
