A stepless speed reducer

Abstract

The invention relates to a stepless-speed-change speed reducer, belonging to the technical field of mechanical engineering. The stepless-speed-change speed reducer comprises a wheel train, an energy storage device, a transmission gear, a main control panel, a speed sensor, a case body, a main shaft and a case cover, wherein the case cover is installed on the case body; the main shaft is installed in the case body; the wheel train is installed on one end of the main shaft and positioned in the case body; the transmission gear is installed in the case body and positioned on the side part of the wheel train; the energy storage device is installed on the other end of the main shaft and positioned on one side of the transmission gear; and one end of the main control panel is connected with the transmission gear, and the other end is connected with the wheel train through the speed sensor. An electromagnetic clutch is utilized to control energy flowing into the output panel so as to control the rotation speed of the output panel. The stepless-speed-change speed reducer has the advantages of compact structure and small size, can effectively save the space, and is easy for popularization and application. The device can implement constant rotation speed output under the condition of unstable input rotation speed, and can lower the requirements for input power in the environment with requirements for output rotation speed. A singlechip, PLC (programmable logic controller) or the like is utilized to control the rotation speed of the output panel, so that the rotation speed of the output panel can be set freely.

Description

technical field [0001] The invention relates to a continuously variable speed reducer, which belongs to the technical field of mechanical engineering. Background technique [0002] The differential gear reducer is a widely used industrial product, which is widely used in engineering machinery, lifting transportation, medical machinery, light work textiles, construction machinery and other mechanical products. There is a 2K-H differential gear train in the differential gear train, which is composed of two sun gears (2K) and a planetary carrier (H). This mechanism has two degrees of freedom, and generally requires two powers to pass through the above The two center wheels are input and the output is through the planet carrier. This mechanism is widely used in industrial production due to its simple structure. [0003] With the transformation of China's manufacturing industry, electromechanical control will further affect China's industrial manufacturing. There are few reducer...
