RS型共振筛的激振器是弹性连杆式激振器，它是由偏心轴、连杆以及传动橡胶弹簧组成，传动橡胶弹簧是一种串联式弹簧，它的弹性力接近基于线性变化，其刚度通常为主振弹簧等效刚度的1/2-1/5.

RS type resonant vibrating device is an elastic connecting rod type exciter, which is composed of an eccentric shaft, a connecting rod and a rubber spring, and the transmission spring is a series spring, which is close to the linear change, and its stiffness is usually based on the equivalent stiffness of the spring 1/2-1/ 5

我国自形设计制造的质量比为1：1的双筛箱共振器。这种筛机的上筛箱和下筛箱分别用金属螺旋弹簧安装在基础上，该弹簧起着隔振作用，为了保持筛箱之间的相对位置，在两筛箱之间，为了使筛箱之间，为了使筛箱受力均匀，组合弹簧沿筛长方向均匀分布，下筛箱上装有偏心轴。当偏心轴旋转时，通过弹性传动连杆，将激振力传递到筛箱上，使筛箱的受力均匀，组合弹簧沿筛长方向均匀布置，下筛箱装有偏心轴。当偏心轴转动时，通过弹性传动连杆，将激振力传递到筛箱上，使筛箱作方向角为45度的直线振动。

The quality of the design of China's manufacturing euhedral ratio of 1:1 double sieve box resonator. On the basis of the metal coil spring, the spring is installed on the base of the screen box and the lower sieve box. In order to keep the relative position between the sieve box, in order to make the screen box, to make the screen box is uniform, the spring is arranged on the screen. When the eccentric shaft rotates, through the elastic transmission connecting rod, the vibration force is transmitted to the screen box, so that the screen box is uniform and the spring is arranged evenly along the direction of the screen. When the eccentric shaft rotates, the vibration force is transmitted through the connecting rod, and the vibration force is transmitted to the screen box, and the direction angle of the screen box is 45 degrees.

该筛与RS型共振筛比较，优点是：

The comparison between the sieve and the RS type resonance sieve has the advantages of:

1由于取消了重量很大的平衡架，筛机重量减轻，金属消耗量小，同质量比为1:3的共振筛相比，筛机的尺寸相等，其重量也可以减少一半。

1 due to the abolition of the weight of a large balance frame, weight loss, metal consumption is small, compared with the same mass ratio of 1:3, the size of the sieve is equal, the weight can be reduced by half.

2两层筛面同时工作，筛面工作面积大。

Two 2 story screen, the working area of the screen is large.

3由于上筛和筛箱的合成重量小，因此，可以采用刚度较小的隔振弹簧，这样也能达到减小作用在基础上的动载荷的目的。

3 because of the low weight of the upper sieve and sieve box, so that the stiffness of the smaller vibration spring, which can also achieve the purpose of reducing the role of the dynamic load on the basis of.

4在筛机工作时，两筛箱的运动方向相差180度，所以筛箱传给地基的载荷也相差180度，动载荷可以互相平衡，因此，基础所受的动复合很小、

4 when the screen machine works, the movement direction of the two screen box is 180 degrees, so the load on the ground of the screen box is different from 180 degrees, and the dynamic load can be balanced,

这种筛机也是质量比为1:1的双筛箱共振筛，它与15平方米共振筛相比，主要区别是取消了线性共振筛机弹簧（串联弹簧）只保留非线性主振动筛，根据动力学分析，只采用非线性主振弹簧的共振筛，筛机具有较大的加速度，从而有利于物料的分级和脱水，不过，由于没有串联线性主振弹簧，控制非线性主振筛弹簧与打击板之间的间隙不变。

The main difference is that the linear resonance screen (series spring) is the main vibration screen, and the screen machine has a large acceleration, which is beneficial to the material classification and dehydration, but because there is no gap between the 1:1 and the striking plate, the main difference is that the linear resonance screen is removed.
