[0021] The specific embodiment of the present invention will be further described in conjunction with the accompanying drawings.

[0022] The processed chamfering tool is shown in Figure 1: its working parameters are as follows:

[0023] Modulus m n = 3,

[0024] Number of teeth Z=36,

[0025] pressure angle α n = 20°,

[0026] Circle-splitting helix angle β=17°right-handed.

[0027] The parameters of the processed chamfering tool are as follows:

[0028] modulus m=3,

[0029] Number of teeth Z q = 46,

[0030] pressure angle α n = 20°,

[0031] Left helix angle β L = 37° left-handed,

[0032] Right helix angle β R = 3° dextrorotation,

Abstract

The invention relates to a production processing technology of dual-surface tooth profile chamfering cutter used for a cylindrical gear, belonging to the technical field of tool processing for chamfering gears, the process technology solves the problem that the processing technology of the dual-surface chamfering cutter in the prior art is complex. The production processing technology of dual-surface tooth profile chamfering cutter used for a cylindrical gear comprises the following steps of the hobbling processes: 1. the helical tooth is hobbed on a hobbing machine by a gear hob; 2. a back taper angle Alphai is hobbed, the starting position of hobbing of the gear hob is that H is equal to Rgsin Alphai and T is equal to Htg Alphai; 3. the tooth thickness of the large end is kept unchanged, the left tooth surface of the reverse tapered teeth is hobbed by a first tooth at the right end of the hob; 4. the right tooth surface of the reverse tapered teeth is hobbed by a first tooth of the left end of the hob. The process has the beneficial effects that operations completed originally by a plurality of processes and a plurality of cutters of the chamfering cutter can be completed by a single hob and special cutters are not required, the method is simple, the precision is reliable, secondary cutter is less used and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of tool processing for gear chamfering, and in particular relates to a production and processing technology for a cylindrical gear double-sided tooth profile chamfering tool. Background technique [0002] Gear chamfering plays an important role in reducing gear noise. At present, the best gear chamfering process is edge extrusion process. The equipment used in this process can already be manufactured in China. However, there is no good domestic processing method for the double-sided chamfering tools used. In the past, most of these tools were imported, with high cost and long order cycle. Domestic manufacturing and processing of edge-extruding knives with large cone angles and different helix angles on the left and right tooth surfaces requires the use of several cutters with different moduli and pressure angles to process the left and right tooth surfaces separately, requiring several processes to complete...
