转盘轴承的代号表示法</SPAN>
一、代号的构成</SPAN>
轴承代号由基本代号和后置代号组成。</SPAN>
二、基本代号的构成</SPAN>
基本代号分为三部分，前部为结构型式和传动型式代号，中部为滚动体直径（对两排以上滚动体的轴承为最大滚动体直径），后部为滚动体中心圆直径（对两排以上滚动体的轴承为最大滚动体中心圆直径）</SPAN>
1</SPAN>、结构型式代号按表</SPAN>1</SPAN>的规定。</SPAN>
01</SPAN>四点接触球轴承</SPAN>02</SPAN>双排异径球轴承</SPAN>11</SPAN>交叉圆柱滚子轴承</SPAN>13</SPAN>三排圆柱滚子组合轴承</SPAN>
2</SPAN>、传动型式代号按表</SPAN>2</SPAN>的规定。</SPAN>
0</SPAN>无齿式</SPAN>1</SPAN>渐开线圆柱齿轮外齿较小模数</SPAN>2</SPAN>渐开线圆柱齿轮外齿较大模数</SPAN>3</SPAN>渐开线圆柱齿轮内齿较小模数</SPAN>4</SPAN>渐开线圆柱齿轮内齿较大模数</SPAN>3</SPAN>基本代号编制规则基本代号编排时，结构型式代号和传动型式代号连写，前部、中部和后部之间用“</SPAN>.</SPAN>”隔开。</SPAN>
