角接触球轴承 7302 BECBP
角接触球轴承能够承受径向载荷和轴向载荷。 单列角接触球轴承只能承受单方向的轴向载荷,因此通常采用成对安装。 作为配对轴承,它们的预紧更加方便。 保持架由黄铜、合成树脂或其他受制于个别轴承特性和应用条件的轴承制成。
根据安装控件要求不同,MONTON角接触球轴承拥有70、72和719等不同系列轴承。在速度较高或径向间隙极小时,可以选择719或70系列轴承。对于重负荷、速度中等的应用,72系列轴承较为合适。而在刚度要求极为重要的工况,719系列轴承由于包含多个滚动体并且适用于直径较大的主轴,这些因素都有助于使主轴系统具有高刚度。针对目前机床主轴的高速化趋势,本公司还特别研发了适合于高速主轴工况的H系列高速角接触球轴承和HC陶瓷球系列接触角球轴承。
角接触球轴承的内、外圈上都有滚道,而且内、外圈能沿轴承轴向作相 对位移。这类轴承特别适用于承受复合负荷,即径向和轴向同时作用的负 荷。角接触球轴承轴向负荷承受能力随接触角α的增大而增大。接触角为径 向平面内球和滚道的接触点连线与轴承轴线的垂直线间的角度。
角接触球轴承的型号共分为:α=15°的角接触球轴承(70000C型); α=25°的角接触球轴承(70000AC型);α=40°的角接触球轴承(70000B型); 背靠背成对双联角接触球轴承[70000C(AC、B)/DB型];面对面成对双联角 接触球轴承[70000C(AC、B)/DF型];串联成对双联角接触球轴承[70000C (AC、B)/DT型];有装球缺口的双列角接触球轴承(00000型);无装球缺口的 双列角接触球轴承(00000A型);无装球缺口,一面带防尘盖的双列角接触球 轴承(00000A-Z型);无装球缺口,两面带防尘盖的双列角接触球轴承 (00000A-2Z型);无装球缺口,一面带密封圈的双列角接触球轴承(00000ARS型);无装球缺口,两面带密封圈的双列角接触球轴承(00000A-2RS型)等。
