【摘要】：針對某方位轉(zhuǎn)臺面對面排列的角接觸球軸承組件和下軸承內(nèi)外圈需同時定位的結(jié)構(gòu)特點(diǎn),結(jié)合主要承擔(dān)軸向載荷的塑料導(dǎo)軌預(yù)留0.4mm裝配間隙的要求,分析轉(zhuǎn)臺的結(jié)構(gòu)工藝性,討論軸承組件的預(yù)緊和預(yù)緊對基座中心載荷的卸荷作用,探討轉(zhuǎn)臺的軸向載荷主要由基座和托架形成的塑料導(dǎo)軌承載的措施,通過實(shí)踐驗(yàn)證了預(yù)緊量選取和預(yù)緊卸荷值計算的正確性,給出了轉(zhuǎn)臺軸承組件裝配尺寸的控制要求,通過預(yù)緊提高了轉(zhuǎn)臺運(yùn)轉(zhuǎn)的均勻性。
[Abstract]:In view of the structural characteristics of the angular contact ball bearing assembly arranged face to face and the inner and outer ring of the lower bearing, which are arranged face to face of a certain azimuth turntable, combined with the requirement of reserved 0.4mm assembly clearance of plastic guideway bearing axial load, the structural and technological properties of the turntable are analyzed. This paper discusses the unloading effect of bearing assembly preload and preload on the center load of the base, and discusses the measures of bearing the plastic guide rail formed mainly by the base and the bracket in the axial load of the turntable. The correctness of the selection of preload and the calculation of unloading value are verified through practice. The control requirements of assembly size of turntable bearing components are given, and the uniformity of turntable operation is improved by pre-tightening.
