padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">　　织机的启制动机构包括主传动和辅助传动两个主要组成部分,前者驱动织机以正常的转速运转,后者由一慢速电动机驱动,在织机执行找断纬、对织口等一些其他织造辅助功能时起作用。</span></p><p style="max-inline-size: 100%;

margin: 0px; padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">　　一般在电动机与织机之间的功率传递是通过一套电磁离合器和制动器来工作的,它既可保证织机迅速启动和制动,又可便于操作。每当纬纱发生断头或因为发生故障失灵时,要求把织机迅速制动在综平位置附近,以方便操作和处理断纬;每当经纱发生断头时要求迅速制动织机,使其停在上心或综平位置,以便于处理断经;启动时要求织机在转到前心打纬时已获得正常车速,保证第一纬得到确实打纬,防止发生稀路织疵。</span></p><p style="max-inline-size: 100%;

margin: 0px; padding: 0px; cursor: text; 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、重型织机为了迅速启动,应考虑采用离合器启动的结构;宽幅织机的主轴转速较低,可以加装高速轴(中间轴);一些高速织机为了启动、制动有力,或为了缩小离合器以及电动机的外形尺寸,使结构紧凑,亦采用高速轴;多臂、提花织机可加装慢速倒车装置,便于校正启动时的织物组织;这类装置的进一步发展是开发了寻纬装置:在断纬停车后,开口机构及选纬机构能适当倒转,按照织物组织校正梭口,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><p style="max-inline-size: 100%;
