组件规格

定义
A mechanical assembly consisting of a nut that engages with a lead screw and a carriage that provides mounting and guidance, designed to convert the rotary motion of a motor-driven screw into precise linear movement in industrial machinery
工作原理
The nut contains internal threads that mesh with the external threads of a lead screw. When the screw rotates, the nut travels linearly along the screw axis. The carriage provides structural support, maintains alignment, and often includes guidance features to ensure straight-line motion with minimal deflection
材料
Nut: Bronze (C93200)Steel (AISI 4140)or Polymer compositesCarriage: Aluminum alloy (6061-T6) or Steel (AISI 1045)Fasteners: Grade 8.8 or higher steel
Backlash
<0.05 mm
Thread Pitch
2-10 mm
Travel Speed
0.1-2 m/s
Load Capacity
500-5000 N
Repeatability
±0.01 mm
Operating Temperature
-20°C to 120°C
标准
ISO 3408DIN 69051JIS B1192

常见问题

What is the difference between a nut/carriage and a ball screw assembly?

Nut/carriage assemblies typically use acme or trapezoidal threads for cost-effective applications with moderate precision, while ball screw assemblies use recirculating balls for higher efficiency and precision in demanding applications

How do I select the right nut/carriage for my application?

Consider load requirements, speed, precision needs, environmental conditions, and maintenance requirements. Consult manufacturer specifications for dynamic load ratings, backlash tolerance, and lubrication requirements
