定义
A flexible body/spider is a critical elastomeric or polyurethane element within flexible couplings that connects two shafts, allowing for angular, parallel, and axial misalignment while damping vibrations and absorbing shock loads. It provides torsional flexibility to protect connected equipment from torque spikes and reduces wear on bearings and seals.
工作原理
Works through elastic deformation of its flexible material (typically polyurethane or rubber) when torque is applied, allowing it to twist slightly to accommodate shaft misalignment while maintaining torque transmission. The spider-shaped design with multiple legs distributes stress evenly and provides damping characteristics.
材料
Polyurethane (most common)Nitrile rubber (NBR)HytrelNeopreneor other engineered elastomers with specific hardness ratings (typically Shore A 92-98 for polyurethane).
Max RPM
5000-10000
Hardness
Shore A 92-98
Bore Sizes
3-100 mm
Torque Capacity
0.5-5000 Nm
Temperature Range
-40°C to +100°C
Misalignment Compensation
Angular: 1-4°, Parallel: 0.2-3 mm, Axial: ±0.5-2 mm
标准

常见问题

What is the main purpose of a flexible body/spider in couplings?

To transmit torque between shafts while accommodating misalignment (angular, parallel, axial), damping vibrations, and protecting equipment from shock loads through elastic deformation.

How often should flexible spiders be replaced?

Typically every 12-24 months depending on operating conditions, but inspect quarterly for cracks, hardening, or permanent deformation. High-torque or misaligned applications require more frequent replacement.

Can different material spiders be used interchangeably?

No, material properties affect torque capacity, temperature resistance, and chemical compatibility. Always use the manufacturer-specified material for your application requirements.
