Abstract

The invention discloses a macro-micro combination continuously variable transmission of an electromagnet-ultrasonic transducer and a method of the macro-micro combination continuously variable transmission, belonging to the field of transmissions. The macro-micro combination continuously variable transmission comprises a box body (8) which is provided with a front end cover (10) and a rear end cover (3); and the macro-micro combination continuously variable transmission further comprises an input shaft component arranged on the front part of the box body and an output shaft component arranged on the rear part of the box body. According to the device, continuously variable transmission is realized by combining macro control and micro control; the reduction gear is small in size, simple in structure and easy for machining, assembling and using; speed change is continuous and adjustable; response time is short; and control is easy.

Description

technical field [0001] The invention relates to a continuously variable transmission device, in particular to an electromagnet-ultrasonic transducer macro-micro continuously variable transmission device and a method thereof, which belong to the continuously variable transmission in the field of transmissions. Background technique [0002] With the continuous advancement of science and technology and productivity, the design of new transmissions is required to be miniaturized, and the requirements for the accuracy of the output speed are also getting higher and higher. This development trend makes the defects of the existing reducers more and more obvious, such as complex structure, bulky size, low transmission accuracy, and poor impact resistance. The structure of the electromagnet is simple, and its magnetism can be controlled by on and off current; the magnitude of the magnetism can be controlled by the strength of the current or the number of turns of the coil; the ma...
