Calculator for disc compression springs / Disk Yay Hesaplama ve formül
Disk yay ya da tabak yay (İngilizce Belleville washer, Almanca Tellerfeder), konik disk şeklinde olan, darbeli çalışan sistemlerde ard arda birbirini takip eden çok sayıda, cıvata bağlantılarında rondela olarak tek kullanılan, üzerine etki eden kuvvet sebebiyle eğilmeye zorlanan bası yayları ailesinden bir yay çeşididir. Disk yaylar, çok büyük kuvvetlerin ve buna karşılık çok küçük şekil değiştirmenin gerekli olduğu makine konstrüksiyonlarında tercih edilir. Çanak yayı ya da tabak yay olarak da anılır.
