Rolling wheel with 60 degrees and 75 degrees two kinds. Ordinary and semicolons two, ordinary is rolling wire machine rolling wheel and gasket, the semicolon is rolling wire machine rolling wheel in the eccentric sleeve.
Note:
1滚丝机床精度差,振动大,连转不正常不服役。
1 rolling machine tool precision, vibration, even not normal service.
2滚丝模具对位不正,被滚压件发生轴向位移,牙纹受到剪切和挤压两种应力作用。
2 rolling wire mold alignment is not positive, the rolling element is the axial displacement, tooth pattern by shear and extrusion force of two kinds of stress.
Three roll not added to lubricants, caused by dry friction, the tooth tip temperature rapidly increased to over rolling cycle of fire temperature, tooth pattern over tempering is softening occurred chamfer, heap tooth failure.
