The amalgamation power of mechanical sulphide machines is derived from elastic deformations of the various receptors. When it is combined and combined, the upper beams are scratched down, the bottoms are scratched up, the poles are stretched and both of them are scratched outward, and the rotting gears and the lower end of the poles are moved outward. Thus, even new sulphide machines are of good quality and are not worn, and these scratches must have occurred during the modulation. The axis of the sulphide site will be twisted away from the vertical position of the theory, and the axis will be repeated once each time from the theoretical vertical position to the twisted position. That is to say, the axis is transient in an open model. As a result of the curvature of the repulsive components, the emulation of the mould is not evenly distributed in the direction of the circle, and ultimately the external stress is greater than the middle. Some sulfurization plants have taken remedial measures to address this problem, such as pre-positioning of the lower end of the carving gear (with a small angle down the side of the carpentry axis) in the absence of a simulator, as well as the use of wedge fillings on the upper beam, which have a certain effect on the tyres of a given specification and when the sulfurizer is not worn out, but which is significantly reduced when the tyre specifications are changed or the parts of the sulfurized machine are worn. The structure of the two modulus is left-right symmetry, but due to manufacturing errors, absolute symmetry is not possible. Sulphurization plants take various measures to ensure the symmetry of parts, such as co-processing of poles, twinning of walls and use of numerically controlled machine beds, to the extent possible, but it is difficult to achieve absolute symmetry in upper beams, substrates, warp gears, transmission axes and gears. As a result of this symmetrical error, and in order to ensure the flexibility of the machine, the spare parts for the various sports are generally accompanied by a lighter symmetry. If the collage is combined with the upper beam axis and the ware handle (e8/e8), the ware gear axis with the bottom hole (e8/e8), the upper beam axis with the roller (f8/e8), the wheel with the wallboard steering slot (h9/f8), the cumulative gap between the upper beam end, the bottom end and the collage level is 1. 15 to 1. 5 mm, etc. This asymmetry and the presence of these commons further adversely affect the modulation accuracy of the sulfide machines, in particular the repetitive accuracy. The structure of the mechanical sulphide machine also determines the power of the upper beam-cutting axis to be applied to the upper copper cord of the pole, the power of the warp gear axis to be applied to the lower copper rod of the pole and the power of the warp to be applied to the lower copper rod of the pole, as shown in figure 1. Moreover, these links are being rotated under heavy loads, which inevitably results in uneven and more severe wear and tear of the copper casings. The wear and tear of the copper caps will further reduce the modulation accuracy of the sulphide machines. In order to maintain a certain degree of condensation of the sulphide machines, the degree of wear and tear of these copper casings must be regularly checked and replaced in a timely manner。
