防松装置防松装置 LOCKING AGENTS

防松的目的是防止零件在震动和冲击载荷作用下而产生不必要的移动。
The purpose of locking 防松的目的是防止零件在震动和冲击载荷作用下而产生不必要的移动。 The purpose of locking is to prevent structural parts from unwanted displacement as a result of knocking and/or vibration, for example.

Some practical tips with assembling and disassembling retaining rings 弹性挡圈的装配和拆卸工具
Spring washers and toothed spring washers 弹性垫圈和有齿弹性垫圈 Do not use spring washers with upward bent ends unless they are necessary. The damage resulting from the milling action will only increase with repeated use. 尽可能不要弯曲弹簧垫圈的开口端，否则会导致连接件表面被子划伤。

Select the correct type of spring washer for the construction. Cylindrical counterbored bolts require a different spring washer than countersunk bolt joints. 根据结构选择合适的弹性垫圈，圆柱沉头螺栓和圆锥沉头孔所需要的弹性垫圈是不同的。

Pay attention that the toothing of toothed spring washers actually make contact with the contact surfaces of the parts to be joined. For example, with too large bolt holes, use a flat toothed spring washer with internal or external toothing. 必须注意把有齿弹性垫圈的齿与连接件的表面接触。如，对于大螺栓孔，利用一个有内齿或外齿的平齿形弹性垫圈。

DUBO locking spring washers DUBO弹性垫圈
Some practical tips with assembling and disassembling retaining rings 弹性挡圈的装配和拆卸工具 DUBO locking spring washers DUBO弹性垫圈 The nut must be tightened until the outer thickening of the ring is deformed and has risen around the hexagon of the nut. The bolt then has the normal prestress and the nut is completely locked. Excessive tightening of the nut is wrong!

Liquid locking agents 液体防松剂 The following applies to locking by means of liquid synthetic resin（合成树脂）: the better the contact faces touch each other, the thinner the adhesive layer becomes, and the better the joint is. Contact faces must be properly clean and free of grease. Cleaning can be done with specially products. A slightly rough surface increases the strength.

The thickness of spring retainers (s) has a tolerance of h11, while the inner diameter d3 of an external clamping ring has a tolerance of h12 and the outside diameter d3 of an internal clamping ring with H12

When the groove for the retaining ring is close to the end of the shaft or bore, the ring ends are first placed into the groove, and the remaining portion of the ring is then pressed along the circumference of the groove. In this way, the ring distorts(扭曲) least in the radial direction. Placing spring retainers

How to tight bolts or screws 如何拧紧螺栓和螺钉
1、螺钉或螺母与工件贴合的表面要光洁、平整。 2、要保持螺钉或螺母与接触表面的清洁。 3、螺孔内的脏物应清理干净。 4、成组的螺母在拧紧时要按一定的顺序进行。

How to tight bolts or screws 如何拧紧螺栓和螺钉
5、拧紧成组螺母时要做到分次逐步拧紧。（一般不少于三次）。 6、必须按一定的拧紧力矩拧紧。 7、凡有振动或受冲击力的螺纹联接，都有必须采用防松装置。

How to tight stuf bolts 如何拧紧双头螺柱 1、应保证双头螺柱与机体螺纹的配合紧密性。
2、保证双头螺柱轴心线与机体表面垂直。 3、装入双头螺柱时，必须先用润滑油将螺栓、螺孔进行润滑，以免拧入时产生咬住现象。
