Differential multi-drive device

Abstract

A differential multi-drive device comprises a gearbox, a plurality of connectors connected with an installing and machining tool are arranged in the gearbox, the connectors are in drive connection through a motor installed below the gearbox, and the connectors comprise the high-speed connector, the intermediate-speed connector and the low-speed connector; the high-speed connector is in drive connection with the tail end of an output shaft of the motor and generates a first-level rotation speed; the intermediate-speed connector is located on the periphery of the high-speed connector, is in drive connection with the output shaft through a gear train and generates a second-level rotation speed; the low-speed connector is located on the periphery of the intermediate-speed connector, is directly driven by a planetary gear of a planetary gear train, is in drive connection with the output shaft through the planetary gear train and generates a third-level rotation speed. The differential multi-drive device has the advantages that the structure is simple and reasonable, the number of parts is small, the manufacturing cost is low, performance is reliable, transmission is stable and accurate, and the work efficiency of a complete machine is high, and is high in practicability.

Description

technical field [0001] The invention relates to a differential multi-drive device, in particular to a coaxial multi-drive device realized by using the differential principle of a planetary gear train, which belongs to the field of mechanical transmission. Background technique [0002] Chinese Patent Document No. CN202060636U announced on December 7, 2011 an electric food processor with a casing. It is provided with a motor with a motor shaft in the processor, and the motor shaft is connected to Output device for multiple drives with different rotational speeds. However, the structure of this driver is relatively complex, it is two planetary gear trains and a motor spindle to achieve three different speed output, and the third-stage output is limited by the transmission ratio of the second-stage planetary gear train volume, and due to There are many gear trains, so it is relatively complicated, and the third-stage output cannot reach a lower speed under a certain volume, whi...

However, the structure of this driver is relatively complex, it is two planetary gear trains and a motor spindle to achieve three different speed output, and the third-stage output is limited by the transmission ratio of the second-stage planetary gear train volume, and due to There are many gear trains, so it is relatively complicated. Under a certain volume, the third-stage output cannot reach a lower speed, and it cannot meet the needs of users.
