margin: 0px; padding: 0px; cursor: text; text-wrap: nowrap; overflow-wrap: break-word !important; outline: none 0px !important;">　　(4)结构紧凑、性能稳定。</span></p><p style="max-inline-size: 100%; margin-bottom: 0px;

padding: 0px; cursor: text; text-wrap: nowrap; overflow-wrap: break-word !important; outline: none 0px !important;">　　织机的启、制动机构主要由主传动系统组成,驱动织机以正常的转速运转。在电动机与织机之间的功率传递是通过主轴皮带轮和一套电磁制动器来工作的,它既可保证织机迅速启动和制动,又可便于操作。每当纬纱发生断头停车时,要求把织机迅速制动在后死心位置,以方便操作和处理断纬;每当发生经向故障时,要求迅速制动织机,使其停在与纬停相同的位置,以便于处理故障点;启动时要求织机当转到前死心打纬时已获得正常车速,保证第一纬得到正常的打纬,防止发生稀路织疵。</span></p><p style="max-inline-size: 100%;

margin: 0px; padding: 0px; cursor: text; text-wrap: nowrap; overflow-wrap: break-word !important; outline: none 0px !important;">　　良好的传动系统应选择合适的电动机,使其机械性能适应织机运转特性的要求。对织机所用的电动机,除应选定合适的额定功率外,还必须考虑电动机的允许最大转矩和最大转差率等特性参数,在直接式传动系统中还要考虑电动机的启动转矩。另外织机的传动系统还应满足织机的负载条件(轻型或重型织机)、启动和制动及有关操纵和控制的特殊要求。例如:高速、重型织机和宽幅织机,为了迅速启动,应采用超力矩启动电动机(纺织机械电动机中的织机专用电动机);有的喷水织机加装变频装置进行自动寻纬,在断纬停车后,开口机构能适当倒转校正梭口,若与卷取、送经机构自动调整共同配合,还能精确对准织口,方便挡车操作,显著减少或消除开车稀密路.</span></p><section class="_135editor" data-role="paragraph" id="autoparagraph" style="max-inline-size: 100%;
