3results about How to "Play a damping effect" patented technology

The utility model discloses a three -phase asynchronous motor with mute function relates to three -phase asynchronous motor technical field, the utility model discloses a three -phase asynchronous motor still includes: noise reduction mechanism, noise reduction mechanism sets up in the tail of three -phase asynchronous motor, and noise reduction mechanism is used for the noise of tail portion to carry out noise reduction, and sound absorption mechanism, sound absorption mechanism sets up in the output site of three -phase asynchronous motor, the utility model discloses the dust cover is positioned and is inserted with the positioning boss through the U -shaped block of inside, then the dust cover is fixed through screw, and the dust cover is limited with the cooperation of U -shaped block and positioning boss, reduces the shaking of dust cover, and the rubber pad can play the effect of shock attenuation when shaking, improves the mute effect, and the sound absorption cotton is in the rotation of radiating fan, absorbs the noise generated, improves the mute effect again, reduces the noise pollution in working environment greatly, thereby guarantees the comfort degree of staff.

A vibration-controlled elastic bearing with steel spring laminated rubber sheet is provided, comprising an upper connecting plate, a lower connecting plate, and a damping body. Multiple vertically arranged damping springs for absorbing vibration energy are evenly distributed inside the damping body. The upper and lower ends of the damping springs, which penetrate the damping body, are respectively connected to the upper and lower connecting plates via an upper sealing plate located above the damping body and a lower sealing plate located on the lower end face of the damping body. This invention optimizes the internal structure of the elastic bearing to achieve dual vibration control, ensuring reliable damping while improving the load-bearing capacity for large shear forces. It solves the pollution problem associated with traditional core rubber seismic isolation bearings. While the damping springs bear the main dynamic load, it reduces fatigue damage to the damping body, lowers its aging rate, and extends its service life.

The application provides an automatic meal distributing mechanical arm device, belonging to the technical field of automatic meal distribution, comprising a meal taking mechanical arm and a soup storage bin arranged on the side wall of the meal taking mechanical arm, and further comprising a driving mechanism comprising a linear motor with a sliding rail design, a first driving cylinder and a second driving cylinder which are designed below the linear motor and are linked, for driving the meal taking mechanical arm to descend, open and close, take meals, and ascend, translate, descend, open and close, and distribute meals. When taking meals, the second driving cylinder is used to ascend and the internal pressure of the sealing sleeve is reduced, and the elastic connection between the piston rod and the elastic piston ring can play a damping effect, so that the sealing sleeve can automatically inhale air from the soup storage bin during the meal transportation process, the soup is effectively prevented from falling and spilling to pollute the environment during the meal transportation process through the suction of the soup suction hole, and automatic clean meal delivery is realized.
