8圖樣標注
8.1在齒輪工作圖上，應標注齒輪的精度等級和側隙種類。
8.2標注示例
8.2.1齒輪的三個公差組精度指標，采用相同的精度等級時，標注為：
例：齒輪的Ⅰ、Ⅱ、Ⅲ公差組精度等級同為7級，側隙種類為g，標注為：
7 g GB 2363—90
8.2.2齒輪的三個公差組精度指標，采用不同的精度等級時，標注為：
例：齒輪的Ⅰ公差組精度等級為7級，Ⅱ公差組精度等級為7級，Ⅲ公差組精度等級為6級，側隙種類為f標注為：
7—7—6 f GB2363—90
8.2.3當自行規(guī)定齒輪傳動側隙時，側隙種類不標注。此時可在相應側隙指標的公稱尺寸上標注其上下下偏差。
例：齒輪的Ⅰ、Ⅱ、Ⅲ公差組精度等級同為7級，側隙上偏差為-0.008、下偏差-0.050，標注為：
表2齒輪各檢驗項目的公差或極限偏差
