梯形絲桿，因其牙型截面為梯形而得名。傳動效率：梯形絲杠的傳動效率大約是26~46%。傳動速度：梯形絲杠為滑動摩擦，工作時溫升較大，故不可用于高速傳輸。使用壽命：滑動摩擦表面損傷較大，故壽命較低，通常使用時需注意清潔潤滑。自鎖性：自鎖性一般與傳動效率成反比，因此，而梯形絲杠具有一定的自鎖性。經(jīng)濟性：一次完成工藝效率很高，故成本較低。但因滾珠絲桿的發(fā)展，工藝配套設(shè)備的升級轉(zhuǎn)型，將來也許會有所增加。滾珠絲杠由螺桿、螺母、鋼球、預(yù)壓片、反向器、防塵器組成。特點：摩擦損失小、傳動效率高。由于滾珠絲杠副的絲杠軸與絲杠螺母之間有很多滾珠在做滾動運動,所以能得到較高的運動效率，一般可達90~96%。精度高：滾珠絲桿生產(chǎn)設(shè)備都是貴重的高精度設(shè)備，批量化的生產(chǎn)工藝使生產(chǎn)精度盡量避免人為因素對精度的干擾。高速進給和微進給可能：滾珠絲杠副由于是利用滾珠運動，靜摩擦力小，所以啟動力矩極小，不會出現(xiàn)爬行現(xiàn)象，能保證實現(xiàn)精確的微進給。
