Embodiment 1

[0021] Grind m using the gear grinding processing method provided by the present invention n 5.5z54, the steps are as follows: divide the teeth of the gear to be ground into three consecutive groups in the circumferential direction, each group has 18 teeth, and then the teeth in each group are sequentially divided into 9 subgroups, each Each subgroup has 2 teeth; when grinding, first grind the first subgroup in each group in sequence, then grind the second subgroup in each group in sequence, and then grind the group in sequence The third subgroup of, and so on, in this way, each subgroup is ground in sequence, and the cycle is repeated until the grinding of each tooth reaches the design standard.

[0022] Table 5 shows the m ground using the gear grinding method of the present invention n Tooth pitch deviation of 5.5z54 gear; Table 6 is the m grounded by the gear grinding method of the present invention n Radial runout of 5.5z54 gear. By comparing with the prior art grinding resu...

Embodiment 2

[0028] Grind m using the gear grinding processing method provided by the present invention n 5.5z63, the steps are as follows: Divide the teeth of the gear to be ground into seven consecutive groups in the circumferential direction, each group has 9 teeth, and each group of teeth is sequentially divided into 3 subgroups, each subgroup has 3 teeth; when grinding, first grind the first subgroup in each group in sequence, then grind the second subgroup in each group in sequence, and then grind the third subgroup in each group in sequence In this way, each sub-group is ground in sequence, and the cycle is performed until the grinding of each tooth reaches the design standard.

[0029] Table 7 shows the m grounded by the gear grinding method of the present invention n Tooth pitch deviation of 5.5z63 gear; Table 8 is the m measured by the gear grinding method of the present invention n Radial runout of 5.5z63 gear. It can be seen that compared to the prior art grinding results tables 3...

Embodiment 3

[0035] Grind m using the gear grinding processing method provided by the invention n 5.5z43, the steps are as follows: Divide the teeth of the gear to be ground into three consecutive groups in the circumferential direction. The first and second groups have 15 teeth each, and the third group has 13 teeth. Then divide the teeth in the first group and the second group into 3 subgroups in sequence, each subgroup has 5 teeth, and the teeth in the third group are divided into 3 subgroups in sequence, the first subgroup and the first subgroup. The second subgroup has 5 teeth in each subgroup, and the third subgroup has 3 teeth. When grinding, the first subgroup in each group is ground in sequence, and then the first subgroup in each group is ground in sequence. Two sub-groups, and then sequentially grind the third sub-group in each group, and so on, in this way, each sub-group is sequentially ground, and the tool is ground after each sub-group of each group is ground Carry out the sh...

Abstract

The invention discloses a gear grinding processing method, which comprises the following step of dividing teeth of the gear to be subjected to grinding processing into at least two continuous groups sequentially along the circumferential direction; then dividing the teeth in each group into at least two continuous subgroups sequentially; and in the grinding process, firstly grinding first subgroups in all the groups sequentially, then grinding second subgroups in all the groups sequentially, grinding all the subgroups sequentially in the manner, and repeating the operations until all teeth are ground to achieve the design standard. The gear grinding processing, which is provided by the invention, is scientific and reasonable, is beneficial to overcoming of various defects in the prior artand achieves the effect of reducing the circular runout of the gear and the circular pitch deviation.

Description

Technical field [0001] The embodiment of the present invention relates to gear processing technology, in particular to a gear grinding processing method. Background technique [0002] At present, the commonly used gear grinding methods mainly adopt the operation process of rough grinding, semi-finish grinding and fine grinding. The main parameters of gear grinding performance testing are gear radial runout and pitch deviation. The feed per stroke for rough grinding is slightly larger, basically 0.03mm, the feed per stroke for semi-finish grinding is 0.02mm, and the feed per stroke for fine grinding is 0.01mm. The speed of the grinding wheel for rough grinding is also different from that for fine grinding. This kind of grinding method can still achieve the 6-level accuracy of the gear tooth profile and tooth direction, but when strictly supervising the value of the pitch deviation (Fp) and radial runout (Fr), it often exceeds the 6-level accuracy tolerance value. phenomenon. So...
