Embodiment Construction

[0032] The present invention comprises the following steps:

[0033] (I) Manufacture of worm gear

[0034] A. According to the parameters of the worm wheel in the worm gear pair to be processed, select the gear hob with the same modulus and tooth profile angle as the modulus m and tooth profile angle α of the worm wheel;

[0035] B. Adjust the angle of the gear hob according to the lift angle λ of the worm in the worm gear pair to be processed, so that the worm gear with the same helix angle as the worm lift angle λ can be processed.

[0036] (Ⅱ) Manufacture of worm

[0037] a. Calculate the turning tool tooth profile angle α for processing the worm according to the parameters of the worm in the worm gear pair to be processed t ;

[0038] b. According to the calculated turning tool tooth profile angle α t Create corresponding tool setting samples;

[0039] c. Sharpen the turning tool according to the tool setting template;

[0040] d. Install the tool and turn the workpi...

Abstract

The invention relates to a machining method for a worm gear pair. The machining method for the worm gear pair comprises the following steps that a gear hob of which the modulus and the tooth profile angle are the same as the modulus m and the tooth profile angle alpha of a worm gear is selected according to the parameters of the worm gear in the worm gear pair needing to be machined to enable the gear hob to machine the worm gear of which the helical angle is the same as the lift angle lambda of a worm; the tooth profile angle alphat of a lathe tool used for machining the worm is calculated according to the parameters of the worm in the worm gear pair needing to be machined; a corresponding tool setting sample plate is manufactured according to the calculated tooth profile angle alphat of the lathe tool; blade grinding of the lathe tool is performed according to the tool setting sample plate; tool packing is performed and lathing is performed on a workpiece. According to the machining method for the worm gear pair, the blade grinding angle of the lathe tool can be quickly calculated, machining of the worm is convenient and fast, and the meshed effect of the manufactured worm and worm gear is good.

Description

technical field [0001] The invention relates to the field of worm manufacturing, in particular to a processing method for a worm gear pair. Background technique [0002] The worm gear pair is one of the commonly used transmission structures, and the stability of its transmission is one of the factors that people choose it. The worm gear pair mainly includes worm gear and worm. The correct meshing conditions of the worm and the worm wheel are as follows: 1. The normal base joints are equal; 2. The lead angle of the worm is equal to the helix lead angle of the worm wheel, and the direction of rotation is the same. The above condition 2 is not difficult to achieve, but it is difficult to achieve the normal base joints to be equal. [0003] When machining cylindrical gears, as long as the modulus (m) and tooth profile angle (α) of the gear hob are the same as those of the gear, various cylindrical gears can be processed. However, when processing worm gears, in addition to the...
