The axial interference shaft comprises a mandrel, a carbon fiber sleeve, an upper opening clamping hoop, a lower opening clamping hoop, a right-angle connector and a stretching mechanism. One end of the core shaft is arranged in the stretching mechanism, the end, located in the stretching mechanism, of the core shaft is connected with the first connector, one end of the core shaft penetrates through the stretching mechanism and then is arranged in the carbon fiber sleeve, one end of the carbon fiber sleeve is attached to the stretching mechanism, and the other end of the carbon fiber sleeve is matched with the opening upper and lower clamp in a clamped mode; a first threaded hole is formed in the end, close to the stretching mechanism, of the mandrel, an inner hole is formed in the mandrel, the inner hole and the first threaded hole are communicated and located on the same transverse axis, a third threaded hole is formed in the end, away from the stretching mechanism, of the mandrel, and a right-angle connector is arranged in the third threaded hole in a threaded fit mode. The mandrel is not prone to generating relative displacement with the carbon fiber sleeve when the temperature changes.

    一种轴向过盈轴,所述轴向过盈轴包括芯轴、碳纤维套筒、口部上下卡箍、直角接头与拉伸机构;所述芯轴的一端设置在拉伸机构内,芯轴位于拉伸机构内的一端与第一接头连接,芯轴的一端贯穿拉伸机构后设置在碳纤维套筒内,碳纤维套筒的一端与拉伸机构贴合设置,碳纤维套筒的另一端与口部上下卡箍卡接配合;所述芯轴靠近拉伸机构的一端开设有第一螺纹孔,芯轴内开设有内部孔,内部孔与所述第一螺纹孔连通且位于同一横向轴线上,芯轴远离拉伸机构的一端开设有第三螺纹孔,第三螺纹孔内螺纹配合有直角接头。本发明温度变化下芯轴不容易与碳纤维套筒产生相对位移。
