    首頁:新聞技術 >> 托輥軸承的安裝配合與調整
    托輥軸承的配合和游隙:由于托輥軸承既要按高精度軸承要求,又要按高溫軸承要求,所以在考慮其配合和游隙時,要顧及下面兩點: The matching and clearance of the roller bearing: because the roller bearing is required for high precision bearing and high temperature bearing, the following two points should be taken into consideration when considering its cooperation and clearance. 1、由常溫升至高溫時的尺寸變化和硬度變化; 1. Change of dimension and hardness of temperature rising to high temperature; 2、高速下離心力所引起的力系變化和形狀變化。 2. Changes in force and shape caused by centrifugal force at high speed. 總之,在高速、高溫的條件下,從配合和游隙的選擇上要力求保持軸承的精度和工作性能,這是有難度的。 In conclusion, it is difficult to maintain the accuracy and performance of the bearing in the high speed and high temperature conditions. 為了保證軸承安裝后的滾道變形小,過盈配合的過盈量不能取得太大,而高速下的離心力和高溫下的熱膨脹,或是抵銷配合表面的法向壓力。或是使配合面松弛,因此過盈量必須在考慮上述兩種因素的前提下審慎地加以計算,在常溫常速下有效的過盈量對于托輥軸承可能是無效的。 To ensure the bearing raceway deformation after the installation is small, the amount of interference interference fit can't get too big, and under the high speed centrifugal force and high temperature thermal expansion, or on the surface of the offset with the normal pressure. Or make the matching surface relaxation, thus interference quantity must under the premise of considering these two factors determine prudently, effectively under the constant velocity of the amount of interference for roller bearings may be invalid.
