定义
Specialized sealing components installed in ball screw nut housings and other drive mechanism enclosures to create barriers against external contaminants (dust, chips, moisture) while retaining internal lubricants. These components typically include lip seals, wiper seals, and combination seals designed for linear motion applications with precise clearance requirements.
工作原理
Seals function through elastic deformation and contact pressure against moving surfaces to create physical barriers. Wiper seals use scraping or wiping action to remove contaminants from shafts or screws before they enter the housing. Combination seals integrate both sealing and wiping functions in a single component through multi-lip designs that maintain consistent contact despite wear.
材料
Nitrile rubber (NBR)polyurethane (PU)fluorocarbon (FKM/Viton)polytetrafluoroethylene (PTFE)fabric-reinforced elastomers. Material selection based on temperature range (-40°C to 200°C)chemical resistanceand wear characteristics.
Hardness
70-90 Shore A
Clearance
0.1-0.3 mm
Shaft Speed
Up to 2 m/s
Pressure Rating
0-0.5 MPa
Operating Temperature
-40°C to 150°C

常见问题

What is the difference between seals and wipers in drive mechanisms?

Seals primarily prevent lubricant leakage and contamination ingress through static sealing, while wipers actively remove contaminants from moving surfaces before they enter the housing. Many modern components combine both functions.

How often should drive mechanism seals be replaced?

Replacement intervals depend on operating conditions: typically 6-24 months in normal industrial environments, or based on visual inspection for wear, hardening, or damage during routine maintenance.
