The twisting direction design of the stainless steel wire is very important

In some mechanical equipment, stainless steel wire needs to play a role together with pulleys or drums. Yasheng stainless steel wire reminds everyone that equipment designers should pay attention to choosing the correct twisting direction of the stainless steel wire. If the twists are handled incorrectly, the stainless steel will be directly shortened. The service life of the cord. When designing mechanical equipment, the designer should try to keep the twisting direction of the stainless steel wire consistent with the position of the roller or pulley, so that the stainless steel wire forms a twist in the same direction, also called L twist. If the stainless steel wire is designed to be twisted in the reverse direction, the service life of the stainless steel wire will be reduced by 50%~70% compared with the condition of the same direction twists. This is because when the stainless steel wire twists in the reverse direction, it will be subjected to tortuous pressure and lateral pressure at the same time. .

Therefore, when designing this type of equipment, the designer should try to prevent the stainless steel wire from being twisted in the opposite direction. If it is necessary to design the reverse tortuous direction, the spacing distance between the pulleys or the rollers should be designed to be larger. It is worth mentioning that because the stainless steel wire is used in direct contact with the pulley or drum in the equipment, the performance of the pulley and drum will have a great impact on the service condition and operating life of the stainless steel wire. In order to prevent the stainless steel wire from being scrapped prematurely, the designer should fully consider the material and diameter of the pulley and drum, and carry out a reasonable design.

What should be paid attention to when the stainless steel wire is threaded around

The correct threading and winding operations should be carried out in accordance with the following: because the stainless steel wire will rotate in the loose twist direction when it is subjected to external tension. Once the loose twist occurs, it will further evolve into deformation and damage, so when it is wound on the reel It is necessary to pay attention to prevent the loose twist of the stainless steel wire, and its winding direction should be determined according to the twisting direction of the rope body. In addition to ensuring the correct winding direction, it is also necessary to arrange the stainless steel wire neatly, especially the section of the winding drum that needs to be tightened so that the rope body is evenly wound. If the first layer is placed disorderly and unevenly, then the subsequent rope placement will inevitably be skewed and pinched.
