The invention discloses a paired bearing differential motion holder dynamic characteristic test device. Inner rings and outer rings of paired bearings are connected respectively and rotate synchronously, and an electric spindle drives the inner rings to rotate and controls the rotation speed of a holder of the bearings, so that the inner rings drive the outer rings through friction between a ball and a roller path to rotate, and differential motion of the inner rings and the outer rings of the tested bearings and controlling over the holder rotation speed are achieved; a corresponding tooth-embed type high-precision holder rotation speed control driving mechanism is arranged, a holder connecting sleeve is connected with the holder of the bearings in an embedded mode and connected with a toothed synchronous belt wheel, and a stepping motor controls the rotation speed of the holder through toothed synchronous belt transmission. A loading part is located between the outer rings of the paired bearings and achieves axial constant pressure loading through a compression spring, and in a measuring part, a laser vibrometer is placed in the axial direction of the tested bearings to measure the swing vibration and vortex motion conditions of the holder. The device is ingenious in structure, no special processing needs to be conducted on the tested bearing, and when the differential motion of the inner rings and the outer rings of the tested bearings exists, the holder dynamic characteristic measurement is achieved.

The invention provides a fluid atomizing nozzle, a density measuring device with the nozzle and a drying device with the nozzle. According to the fluid atomizing nozzle, fluid enters the atomizing nozzle in the tangential direction of the side wall of the atomizing nozzle, the ratio of the upper diameter to the lower diameter of an inner cavity of the nozzle is increased, the methods that the rotating direction of the fluid is controlled, and the outlet diameters and number of single-hole sprayers on different atomizing nozzles, fluid pressure, measurement and the like are adjusted are adopted, and rotation of the fluid is improved. When angular momentums of multiple kinds of fluid are the same in size and opposite in direction, mixing among the fluid can be enhanced, the side effect that single fluid enters the inner cavity of the nozzle in the tangential direction can be avoided, and positive effects are generated for improving fuel combustion performance and driving force of rockets and jet aircrafts and on other occasions needing uniform atomizing density; when umbrella-shaped fog columns are needed, rotation of the multiple kinds of fluid can be controlled to be identical to achieve the effect of increasing the diameter of large particles. The effects that the needed minimum pressure is small and the fluid rotates at an ultra-high speed can be achieved without adding a rotating part.

Embodiments of the present invention provide a method and device for controlling the operation of a rotating motor. The rotating motor drives a rotating tray to rotate, and materials are placed on the tray. The method includes: calculating the compensation pulse when the rotating motor rotates; Calculate the number of forward intervals and the number of reverse intervals for the material to move from the current position in the rotating tray to the target position; based on the compensation pulse, the number of reverse intervals, the number of forward intervals and the rotation motor The direction of the last rotation determines the pulse required to drive the material from the current position to the target position; the pulse is used to drive the rotating motor to rotate to move the material from the current position to the target position.
