Example Embodiment

[0018] The present invention will be described in detail below with reference to the drawings and embodiments.

[0019] Refer to figure 1 And FIG. 2, an embodiment of the gear manufacturing method of the present invention includes a feature design step 11, a forming step 12, and a post-processing step 13. The manufacturing method is matched with a molding device 2.

[0020] Refer to figure 2 , image 3 and Figure 4 The molding device 2 includes a base 3 and a plurality of rollers 4 pivoted on the base 3. The base 3 includes a body portion 31 surrounding a space 310 and a number of spacer portions 32 arranged at equal angles and spaced in the space 310. The spacer 32 divides the space 310 into a plurality of accommodating grooves 33 arranged at equal angular intervals and a through groove 34 connected to the accommodating groove 33. The rollers 4 are pivoted in the accommodating groove 33 of the base 3 respectively, and partially extend into the through groove 34. Each roller 4...

Abstract

Provided are a gear forming device and a gear manufacturing method. The gear forming device comprises a base and a plurality of idler wheels. The base comprises a body part defining a space, and a plurality of spacing parts which are arranged in the space at intervals and at equal angles. The space is divided into a plurality of containing grooves and a through groove communicating with the containing grooves through the spacing parts. The idler wheels are arranged in the containing grooves of the base in a pivoted mode correspondingly, and part of the idler wheels extend into the through groove, and thus a mold hole corresponding to the tooth form feature of a gear is defined. A bar can be processed to form the tooth form feature after passing through the mold hole, and a plurality of spur gears are obtained after post-processing is conducted.

Description

technical field [0001] The invention relates to a forming device and a manufacturing method of a gear, in particular to a forming device and a manufacturing method of a net shape of a spur gear. Background technique [0002] Spur gears are the most basic form of gears, and are generally used in various fields for power transmission, deceleration, and steering changes. Traditionally spur gears are manufactured by cutting the material with a milling tool such that the outer surface of the bar is cut with toothed features. However, cutting processing is a subtractive processing method, that is, a whole piece of material will be continuously subtracted during the processing process, resulting in low material yield and waste. In addition, each spur gear has a plurality of teeth, but the above-mentioned processing method must cut each tooth separately, resulting in low production efficiency. [0003] Although there is also a method of directly net-shaping spur gears by forging t...
