Other names SL Cross Slider coupling and SL coupling SL Oldham Coupling SL Type Coupling.
SL Coupling Model feature:
SL coupling and oldham coupling is a kind of oldham coupling model. SL oldham coupling has two face with radial grooves of the half coupling with a tenon is at each end and middle of the slider. Middle perpendicular to tenon on both ends of the slider. Respectively embedded into the groove of the two and a half coupling again.
The material of SL cross slider coupling is 45 steel. and the working surface needs heat treatment to improve its hardness. Q275 steel is also available at lower requirements. Without heat treatment. In order to reduce the friction and wear. the oil should be injected into the oil hole of the middle disk for lubrication. The middle plate will produce a large centrifugal force. thus increasing the dynamic load and wear.
Coupling SL Model advantage:
SL Coupling is generally used for speed n<250r/min. the shaft stiffness is large. And no violent impact. Allowable compensation amount of SL cross slider coupling. axial delta x=1~2mm, radial y 0.04d(d is axial diameter). Angular 40 ‘speed generally not exceeding 300r/min.
