Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings. The embodiment of the present invention uses a four-axis machining center to process a gear with a small number of teeth. Take the gear with a small number of teeth in the parameters in Table 1 as an example:

[0043] Table 1 embodiment gear parameter table with few teeth

[0044]

[0045] The first step, refer to image 3 As shown, for the convenience of clamping and the need for tool retraction during processing, the blank needs to be made into a stepped shaft structure. According to the parameters in Table 1, the blank is first processed into a stepped shaft with a diameter of 40.01mm. In this step, in order to save the man-hours of the machining center, ordinary machine tools can be used to process the blank into a stepped shaft ...

Abstract

The invention relates to the technical field of machining of gears with fewer teeth, in particular to a numerical control machining method of gears with fewer teeth. Through a four-axis numerical control machine tool for machining the gears with fewer teeth, the numerical control machining method of the gears with fewer teeth includes the steps of work blank pretreatment, modeling, tool path planning, rough machining, semi-fine machining and fine machining, and high-precision milling of a tooth face of the gears with fewer teeth can be achieved. The numerical control machining method of the gears with fewer teeth is applicable to milling of the gears with fewer teeth with different parameters, and has the advantages of high machining efficiency, high precision and high finished product quality.

Description

technical field [0001] The invention relates to the technical field of gear machining with a small number of teeth, in particular to a numerical control machining method for a gear with a small number of teeth. Background technique [0002] In the 1980s, the former Shaanxi Institute of Technology (now Shaanxi University of Technology) proposed a new type of gear—a gear with a small number of teeth. Gear transmission is an important component and extension of involute gear transmission. It has been maturely applied in motorcycle engines and other products in foreign countries, and there are also attempts to apply it in fields such as mopeds and electric bicycles in China. It has the advantages of large transmission ratio and small size. , especially suitable for occasions with small and medium power, limited structural size and large transmission ratio. Gears with a small number of teeth are very suitable for the needs of modern development and have high application value. ...
