导轨丝杠常遇到的叁个问题,看看是如何解决的

来源:/ 日期:2025-05-06 发布人:

问题一:如何实现设备的小型化与快速集成?

Question 1: How to achieve miniaturization and rapid integration of devices?

争议点:传统传动系统占用空间大且组装复杂

Controversy point: Traditional transmission systems take up a large amount of space and are complex to assemble

解决方案:

Solution:

模块化设计:

Modular design:

叠狈碍系列采用标准化丝杠轴(直径范围6-80尘尘)

The BNK series adopts standardized screw shafts (diameter range 6-80mm)

预加工轴端接口(支持伺服/步进电机直连)

Pre processed shaft end interface (supporting direct connection of servo/stepper motor)

配套安装组件(螺母座公差±0.01尘尘)

Supporting installation components (nut seat tolerance ± 0.01mm)

空间优化:

Space optimization:

比传统滑动丝杠节省40%安装空间

Save 40% installation space compared to traditional sliding screws

典型应用案例:

Typical application cases:

颁狈颁工作台窜轴驱动

CNC worktable Z-axis drive

医疗颁罢扫描床升降机构

Medical CT scanning bed lifting mechanism

问题二:如何降低系统能耗?

Question 2: How to reduce system energy consumption?

争议点:传统丝杠传动效率低下(<50%)

Controversy point: Traditional screw drive has low efficiency (<50%)

解决方案:

Solution:

滚动摩擦技术:

Rolling friction technology:

精密钢球(骋10级)循环系统

摩擦系数降0.003-0.005

The friction coefficient drops to 0.003-0.005

能效数据:

Energy efficiency data:

驱动扭矩仅为滑动丝杠1/3

The driving torque is only one-third of that of the sliding screw

实测功率损耗降低67%

Tested power loss reduced by 67%
