Problems solved by technology

[0002] The existing screw driving method, because it uses a pulley and a nut on the screw, takes up a lot of space, has low efficiency, and has high transmission noise. However, this transmission method can only drive one nut to drive, and the positioning accuracy is poor, and the nut is easily worn by eccentric force.
Therefore, the application of screw ladders in the field of villa ladders is very limited and can only be used in some special fields

Abstract

The invention provides a novel screw driving device, comprising: a motor assembly, a screw, an upper nut and a lower nut; a motor assembly includes a motor housing, a motor stator, a magnet, a motor rotor, and a screw motor shaft. The screw motor shaft is sleeved outside the screw by a hollow structure. The motor rotor is sleeved outside the screw motor shaft and fixed on the screw motor shaft. The screw motor shaft and the motor rotor rotate synchronously; a magnet steel is sleeve on that rotor of the motor. The stator of the motor is sleeved outside the magnet steel. The motor housing is sleeved outside the motor stator, and the motor housing is fixedly connected with the motor stator; Both ends of the screw motor shaft extend out of the motor housing. The upper nut and the lower nut arerespectively fixed on both ends of the screw motor shaft; and the upper nut and the lower nut are respectively engaged with the screw. The invention has the advantages that the double nuts are directly positioned and the hollow shaft of the motor directly drives the nuts at both ends to run, thereby saving the space occupied by the traction machine, improving the transmission efficiency, reducingthe vibration of the whole machine, reducing the wear caused by the eccentricity of the nuts, and prolonging the service life of the whole machine.

Description

technical field [0001] The invention relates to a driving device, in particular to a novel screw driving device and a preparation method. Background technique [0002] The existing screw driving method, because it uses a pulley and a nut on the screw, takes up a lot of space, has low efficiency, and has high transmission noise. However, this transmission method can only drive one nut to drive, and the positioning accuracy is poor, and the nut is easily worn by eccentric force. . Therefore, the application of screw ladders in the field of villa ladders is very limited and can only be used in some special fields. Contents of the invention [0003] A new type of screw driving device provided by the present invention breaks through the structural form of the traditional screw driving method, adopts double nuts for direct positioning, and the hollow shaft of the motor directly drives the nuts at both ends to run, thereby saving the space occupied by the traction machine and im...
