首页:新闻技术 >> 托辊轴承的安装配合与调整
托辊轴承的配合和游隙:由于托辊轴承既要按高精度轴承要求,又要按高温轴承要求,所以在考虑其配合和游隙时,要顾及下面两点: 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、由常温升至高温时的尺寸变化和硬度变化; 1. Change of dimension and hardness of temperature rising to high temperature; 2、高速下离心力所引起的力系变化和形状变化。 2. Changes in force and shape caused by centrifugal force at high speed. 总之,在高速、高温的条件下,从配合和游隙的选择上要力求保持轴承的精度和工作性能,这是有难度的。 In conclusion, it is difficult to maintain the accuracy and performance of the bearing in the high speed and high temperature conditions. 为了保证轴承安装后的滚道变形小,过盈配合的过盈量不能取得太大,而高速下的离心力和高温下的热膨胀,或是抵销配合表面的法向压力。或是使配合面松弛,因此过盈量必须在考虑上述两种因素的前提下审慎地加以计算,在常温常速下有效的过盈量对于托辊轴承可能是无效的。 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.
