On Hydraulic motor In the whole process of long-term application, you are likely to encounter the condition of loose nuts. So, how should we prevent it Hydraulic motor manufacturer Let's get to know.

1. Self locking nut

In the whole process of application, ordinary nuts will loosen automatically due to vibration and other reasons, such as vibration. In order to avoid such conditions, self-locking nuts are invented. The self-locking nut is mainly used to prevent looseness and shock.

It is used as a unique place. Generally, it is locked by sliding friction. The self-locking nuts are classified according to their functions, including those with polyester rings, necked edges, and metal material locking devices. They all belong to reasonable torque type locknuts. The self-locking nut is difficult to tighten due to its characteristics.

2. Flat washer

The seal ring refers to the part between the connected part and the nut. The metal ring is generally flat, which is used to maintain the surface of the connected part from being scratched by the nut, and to disperse the working pressure of the nut on the connected part.

3. Flat washer and spring washer

Spring washers are widely used in load-bearing and non load-bearing structures of common mechanical equipment products. The utility model has the advantages of low cost, convenient installation, and is suitable for the positions where loading and unloading are frequent. However, the locking capacity of spring washer is very low!

4. Nut locking fluid

Wipe the loosening prevention liquid of the nut to the tightening position of the foundation bolt, and tighten the nut to achieve the actual effect of loosening prevention. Double nut (up and down) locking is also a very good way to tighten and prevent loosening according to the mutual cooperation between a left-hand nut and a left-hand nut.

5. The screw and nut are punched and pinned and fixed

In mechanical equipment, the key of the nut can be used for precise installation and positioning, and can also be used to break the connection of the load in the connection and release pressure level safety device. The types of pins include: cylindrical pins, taper pins, grooved pins, pins and safety pins.
