ERM 工作原理

ERM锁紧螺母在ESL锁紧螺母的基础上增加了一个不可拆卸的锥形弹性垫圈。ERM锁紧螺母附带的锥形弹性垫圈不仅省去了安装螺母时另行配备垫圈的工序,同时可以给连接副提供360°的弹性补偿,增加锁紧效果。可以说是锥形弹性垫圈和双开槽锁紧螺母的双效组合。

 

ERM 基本信息

Definition:reusable slotted self-locking hexagon nut with free washer to SNCF ST 001-02 FPn15.
Threading:standard to ISO 965-2.
Characteristic and performance test: for steel ISO 898-2/ISO 2320 for stainless steel ISO 3506-2/NF E 25-035-2.
Manufacturing range:metric/inch, all diameters, coarse & fine pitch, special heights & A/F upon request.
Quality class:Class8/10(st);A2-70/A4-80(SST).

ERM – HFR FLANGE NUT WITH FREE WASHER

 

The principle of self-locking nut ERM is to compress the flank of the thread of the male element on two sectors located in different planes and offset by 180 °.This principle is obtained by making two calibrated slots in the upper turret of the nut which are then crushed under a specific load to obtain a permanent deformation of the two slots (elastoplastic deformation).

 

During the assembly, the deformed slots in the upper turret of the ERM nut are pushed by the thread of the male element. This thrust generates pressure on the side of the flank of the thread of the male element on two sectors creating a constant locking torque (called self-locking). This self-locking torque is independent of the prevailling torque applied when tightening the ERM nut.

 

The ERM nut has also a mobile conical washer. It flattens during assembly when the male element is tensioned under the effect of tightening torque. In the life cycle of an assembly using an ERM nut, phenomena can lead to a release of the initial tension of the male element. The conical washer will restore the energy stored during compression and maintain part of the tension in the assembly.

ERM nuts are recommended for all common or safe assemblies with risks of loss of initial tension. These voltage losses are generated by settlements, creeps or vibratory phenomena.
Examples:
● several stacked pieces
● assemblies incorporating racks or teeth
● assemblies of parts consisting of low-hardness metals or flexible materials
● assemblies of painted parts
● electrical connection assemblies, etc
