Description

Technical Field

[0001] The utility model relates to the technical field of springs, in particular to a wave spring with a low-frequency vibration isolation function. Background Art

[0002] Wave springs, also known as wave springs, are elastic elements with several peaks and valleys on a thin metal ring. They are usually used in situations where the load and deformation are not large, and where a small spring stiffness is required and an axial preload needs to be applied. Wave springs are particularly suitable for applications that require weight reduction and applications that are restricted by a small installation space.

[0003] At present, most wave springs cannot effectively reduce vibration when in use, resulting in frequent deformation of the wave springs during use, making the wave springs prone to fatigue and unable to return to their original state, with the elastic force disappearing and the service life being short. Therefore, a wave spring with low-frequency vibration isolation function is proposed to solve the above problem. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1In this embodiment, a wave spring with low-frequency vibration isolation function includes a spring body 1. The spring body 1 is a carbon steel sheet. The cost of the carbon steel sheet is low, which makes the cost of manufacturing the wave spring lower. The carbon steel sheet contains a high carbon content. After heat treatment or quenching treatment, its hardness and wear resistance can be effectively improved, so that it can withstand greater pressure and impact. The outer surface of the spring body 1 is coated with a corrosion-resistant layer, and the corrosion-resistant layer is coated with an epoxy coating. After the epoxy coating is cured, an interpenetrating network polymer anti-corrosion coating between the epoxy resin chain and the rubber chain is formed, thereby It effectively prevents the change of the coating and improves the weather resistance of the coating, thereby improving the corrosion resistance of the spring body 1 and increasing the service life of the spring body 1. A plurality of protective pads 2 are fixed to the outer surface of the spring body 1. The protective pads 2 include a vibration-damping layer and a wear-resistant layer. When the spring body 1 is squeezed, the protective pads 2 will be rubbed. The spring body 1 inside the protective pads 2 can be protected by the wear-resistant layer, and the vibration-damping layer can improve the vibration-damping effect of the spring body 1, thereby improving the vibration-damping effect of the wave spring when in use. A vibration-damping mechanism 3 is fixed inside the spring body 1.

[0021] It should be noted that when the spring body 1 is subjected to pressure, the spring body 1 will be compressed, so that the spring body 1 squeezes the vibration reduction mechanism 3, causing the vibration reduction mechanism 3 to operate. Through the operation of the vibration reduction mechanism 3, the pressure on the spring body 1 can be dissipated, so that the spring body 1 can reduce vibration.

[0022] See also Figure 2-3 In order to make the wave spring effectively reduce vibration, the vibration reduction mechanism 3 in this embodiment includes an upper connecting bin 301, a lower connecting bin 302, four rollers 303 and a vibration reduction assembly. The upper connecting bin 301 and the lower connecting bin 302 are respectively provided with movable holes on the opposite sides. The movable holes are adapted to the connecting rod 304. Through the setting of the movable holes, the opening and closing range of the connecting rod 304 can be limited, thereby improving the stability of the vibration reduction mechanism 3 during operation, so that the vibration reduction effect of the wave spring is better. The upper connecting bin 301 and the lower connecting bin 302 are both fixed to the outer surface of the spring body 1, and the four rollers 303 are respectively connected to the inner parts of the upper connecting bin 301 and the lower connecting bin 302 in a rolling manner, and the vibration reduction assembly is fixed between the four rollers 303.

[0023] In this embodiment, the vibration reduction assembly includes two connecting rods 304 and hinge shafts 305. The connecting rods 304 are cross-connected. Through the cross-connection of the two connecting rods 304, the connecting rods 304 will open and close their angles when subjected to pressure, so that the connecting rods 304 can drive the rollers 303 to roll, thereby achieving the purpose of the vibration reduction assembly to operate. Flexible telescopic plates are fixed on the left and right sides of the connecting rods 304, and the flexible telescopic plates are fixed to the upper connecting bin 301 and the lower connecting bin 302. Through the setting of the flexible telescopic plates, dust and oil can be prevented from entering the interior of the upper connecting bin 301 and the lower connecting bin 302, so that the rolling of the rollers 303 in the upper connecting bin 301 and the lower connecting bin 302 can be more stable, thereby improving the operation stability of the vibration reduction mechanism 3 and making the vibration reduction effect of the wave spring better. The two connecting rods 304 are respectively fixed to the four rollers 303, and the hinge shaft 305 is fixed at the intersection of the two connecting rods 304.

[0024] In addition, the vibration reduction assembly also includes four vibration reduction springs 306 , which are respectively fixed to the left and right side walls of the inner cavity of the upper connecting bin 301 and the lower connecting bin 302 , and the opposite sides of the left and right vibration reduction springs 306 are in active contact with the roller 303 .

[0025] It should be noted that when the shock absorbing mechanism 3 is compressed, the distance between the upper connecting chamber 301 and the lower connecting chamber 302 will be reduced, so that the two connecting rods 304 can be opened and closed at an angle. The angle opening and closing of the two connecting rods 304 will drive the roller 303 to roll inside the upper connecting chamber 301 and the lower connecting chamber 302. The rolling of the roller 303 will drive the shock absorbing spring 306 to be compressed, so that the shock absorbing spring 306 can release the pressure on the shock absorbing mechanism 3, thereby achieving the purpose of shock absorbing the spring body 1.

[0026] The working principle of the above embodiment is:

[0027] When the wave spring is subjected to pressure, the spring body 1 will be compressed, so that the spring body 1 squeezes the vibration reduction mechanism 3. At this time, the distance between the upper connecting chamber 301 and the lower connecting chamber 302 will be reduced, so that the two connecting rods 304 can adjust the opening and closing angles through the action of four rollers 303. When the rollers 303 move, the vibration reduction spring 306 will be squeezed, so that the vibration reduction spring 306 is compressed, and the vibration reduction spring 306 will be subjected to force. When the pressure on the spring body 1 disappears, the vibration reduction spring 306 will push the roller 303 to move back, so that the spring body 1 can return to its original shape, thereby achieving the purpose of effectively reducing vibration when the wave spring is in use, thereby improving the service life of the wave spring.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
