钢领是细纱机上完成加捻和卷绕工序的重要零件之一。钢领工作时的受力条件以42~s棉纱为例来说明,当钢领直径为38毫米,锭速为17千转/分,钢丝圈重量为0.02595克时,则钢丝圈的离心力为108克。如果钢领与钢丝圈的实际接触面积为0.15毫米~2时,钢领内跑道表面压力为72公斤/厘米~2。当钢丝圈的线速度接近32米/秒时,钢领与钢丝圈的表面最大压力可超过300公斤/厘米~2。在这样大的压力作用下,必然导致钢领表面磨损,而当钢 The ring is one of the most important parts for completing the twisting and winding processes on the spinning frame. The working conditions of the collar work to 42 ~ s cotton yarn as an example to illustrate that when the collar diameter of 38 mm, spindle speed of 17 thousand rev / min, traveler weight 0.02595 grams, then the traveler of the centrifugal force of 108 G If the actual contact area between the ring and the traveler is 0.15 mm ~ 2, the surface pressure on the runway in the ring is 72 kg / cm ~ 2. When the traveler’s wire speed approaches 32 m / s, the maximum pressure on the surface of the ring and traveler can exceed 300 kg / cm2. Under such a large pressure, it will inevitably lead to the wear and tear of the ring surface, and when the steel
