Description

滚齿机工作台分度蜗杆安装结构
技术领域
本实用新型涉及一种滚齿机工作台分度蜗杆安装结构，属于齿轮加工机床的技术领域。
技术背景
原有技术中滚齿机工作台分度蜗杆多采用普通球轴承旋转支承安装在分度蜗杆托架上，由于分度蜗杆与分度蜗轮啮合传动过程中受到的轴向力较大，普通球轴承往往难以阻止分度蜗杆的轴向移动，影响了分度蜗杆和分度蜗轮间传动的精度，影响了齿轮产品的质量。
发明内容
本实用新型目的在于提供一种能有效阻止工作台分度蜗杆的轴向移动和径向跳动，保证分度蜗杆和分度蜗轮传动的精度，优化了滚齿机工作台分度蜗杆安装结构，解决了原有技术存在的普通球轴承往往难以阻止分度蜗杆的轴向移动和径向跳动，影响了分度蜗杆和分度蜗轮的传动精度，影响了生产齿轮的产品质量。
本实用新型的上述技术目的主要是通过以下技术方案解决的：分度蜗杆旋转支承安装于托架上并与分度蜗轮啮合传动，所述分度蜗杆左端与托架间设有左轴承，分度蜗杆右端与托架间设有右轴承，所述分度蜗杆左轴承作精密径向定位。分度蜗杆靠近右轴承内端面设有右轴台外端面设有锁紧螺母，所述右轴承由左右两端的单向推力球轴承及中间的轴承套构成，除精密径向定位外，同时起可靠的轴向定位作用。轴承套与托架用骑缝销固定。在分度蜗杆和分度蜗轮啮合传动的过程中，阻止分度蜗杆的轴向移动，从而保证分度蜗杆和分度蜗轮传动的精度，提高了齿轮的产品质量。
因此，本实用新型具有能有效阻止工作分度蜗杆的轴向移动和径向跳动，保证分度蜗杆和分度蜗轮传动的精度，提高了齿轮生产的产品质量。
附图说明
附图1是本实用新型的一种结构示意图。
具体实施例
下面通过实施例，并结合附图，对本实用新型的技术方案作进一步具体的说明。
实施例1：如图1所示，分度蜗杆61301旋转支承安装于托架61027上并与分度蜗轮61207啮合传动，分度蜗杆61301左端与托架61027间设有左轴承61205，分度蜗杆61301右端与托架61027间设有右轴承61206，分度蜗杆61301靠近右轴承61206内端面位置设有右轴台613012，外端面设有精密垫圈61302和锁紧螺母，右轴承61206由左右两端的单向推力球轴承51110及中间的轴承套构成，右轴承套用骑缝销与托架固定。左右两端用右轴台和锁紧螺母轴向定位，用左轴承61205和右轴承61206径向定位。
在分度蜗杆和分度蜗轮啮合传动的过程中，分度蜗杆的右轴台与锁紧螺母及两端的单向推力球轴承相抵，阻止分度蜗杆的轴向移动，左轴承及右轴承均为精密轴套，阻止分度蜗杆的径向跳动，从而保证分度蜗杆和分度蜗轮传动的精度，提高了生产齿轮的产品质量。
