Abstract

The invention relates to the technical field of transmission devices, in particular to a three-position switch transmission device which comprises a main shaft, a left driven shaft and a right driven shaft, wherein, the left driven shaft and the right driven shaft are respectively arranged on the two sides of the main shaft; the left driven shaft, the right driven shaft and the main shaft are connected one another through four connecting rod devices; and the main shaft is connected with a bevel gear group which is connected with a crank arm. The three-position switch transmission device has the advantages of simple, compact and reasonable structure, convenience and fastness in assembly, convenience in maintenance, lower maintenance cost, prolonged service life of a three-position switch, greatly improved working reliability of the three-position switch, and easiness in use and popularization.

Description

technical field [0001] The invention relates to the technical field of a transmission device, in particular to a three-position switch transmission device. Background technique [0002] The opening and closing conductive part of the three-position switch of the existing inflatable ring main unit is installed inside the air box. If a fault occurs, the air box must be replaced as a whole. The maintenance is troublesome and the maintenance cost is high, which shortens the use of the three-position switch. Life, greatly reducing the reliability of the three-position switch work. Contents of the invention [0003] In order to overcome the disadvantages of high maintenance cost, short service life and low working reliability of the existing three-position switch, the present invention provides a three-position switch transmission device. [0004] The technical solution adopted by the present invention to solve its technical problems is: a three-position switch transmission devi...
