Machining method for worm gear pair

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...

Problems solved by technology

So it is quite difficult to find a suitable worm gear hob

In reality, when the self-made equipment encounters a worm gear pair that needs to be processed, or when the worm gear pair in the original equipment is damaged and needs to be updated urgently, it becomes a big problem to manufacture the worm and worm gear with good meshing conditions.
