A frictional over-torsion protection structure relates to the technical field of frictional over-torsion protection structure, which includes active flange, friction disc, copper sleeve, compaction disc, compaction plate, driven flange and disc spring. One end of active flange is covered with compaction disc, and between compaction disc and active flange is provided with driven flange. Both upper and lower sides of driven flange are provided with friction disc. Friction disc contacts with active flange. A copper sleeve is arranged at the contact point between the inner side of the moving flange and the active flange. The opposite end of the compacting disc and the active flange is connected with one end of the disc spring and the other end of the disc spring is connected with the pressing plate. When the frictional over-torsion protection structure is disconnected, it can still transmit the torque, which can ensure the normal operation of the unit and ensure that the main engine does not produce the phenomenon of flying car; can withstand multiple disconnection actions; can automatically reset, without operation, after eliminating the overload torque, it can reset synchronously with the start of the main engine; the slipping torque has high accuracy and can be adjusted, and the slipping torque is mainly realized by adjusting the compression of the disc spring, because the disc spring is the main factor. It has stable performance, high adjustment precision and repetitive precision.

一种摩擦超扭保护结构
:本专利技术涉及摩擦超扭保护结构
,具体涉及一种摩擦超扭保护结构。
技术介绍
:随着传动系统的发展,各传动机组的运行工况越来越恶劣,目前大多数机组都存在不定时的瞬时超扭现象。为了避免超扭造成机组破坏,传统解决方法为设计机组时所有部套都留有足够的安全余度,这样造成整个机组的装机成本大大增加。因此需要设计一种超扭保护结构,在机组出现超扭时进行过载保护,又不需其他部套在设计时留有多大的余度。
技术实现思路
:本专利技术的目的是为了克服上述现有技术存在的不足之处,而提供一种摩擦超扭保护结构,它实现了在机组出现超扭时进行过载保护,又不需其他部套在设计时留有多大的余度的工作。本专利技术采用的技术方案为:一种摩擦超扭保护结构,包括主动端法兰、摩擦片、铜套、压紧盘、压板、从动端法兰和碟簧,主动法兰一端套有压紧盘,压紧盘与主动法兰之间设有从动法兰,从动法兰上下侧端面均设有摩擦片,摩擦片与主动法兰相接触,从动法兰内侧与主动法兰接触处设有铜套,所述的压紧盘与主动法兰相反的一端与碟簧一端连接,碟簧另一端与压板连接。本专利技术的有益效果是:本摩擦超扭保护结构脱开时,仍可传递扭矩,可保证机组正常运行,保证了主机不产生飞车现象;可承受多次脱开动作;可自动复位,无需操作,消除过载扭矩后,可随主机的启动同步复位;打滑扭矩精度高且可调,打滑扭矩主要靠调节碟簧的压缩量实现,因碟簧性能稳定,调节精度和重复精度高。附图说明:图1是本专利技术结构示意图。具体实施方式:参照图1,一种摩擦超扭保护结构,包括主动端法兰1、摩擦片2、铜套3、压紧盘4、压板4、从动端法兰6和碟簧7,主 ...
