Planetary multilevel speed reducer for powder coal pair roller briquetting machine

Abstract

The invention relates to a planetary multistage speed reducer for a pair roller molding machine for pulverized coal. A shell connected by a front machine cover 9 and a machine body 4 is provided with an input gear pair; the inside of an inner gear ring I 12 is provided with a floating planetary gear pair; a shell connected by a connecting disc 13, an inner gear ring II 11 and a rear machine cover 3 is provided with an output planetary gear pair; the gear pairs are engaged to form three-stage speed change; the input gear pair is used as high-speed stage input; an output rotary rack II 1 of the output planetary gear pair is used as low-speed stage output; the central axis of the floating planetary gear pair and the central axis of the output planetary gear pair are superposed; and an input shaft 8 of the input gear pair and a sun wheel axle I 10 of the floating planetary gear pair are in parallel arrangement. The input shaft drives a gear 2 and then drives the sun wheel axle I to be engaged with three planetary wheels I 6 and the fixed inner gear ring I, thereby realizing rotation and revolution of the planetary wheel I; further, a rotary rack I 14 and a sun wheel II 7 are driven to rotate; and a planetary wheel II 5 and an output rotary rack 1 are driven to move, thereby realizing the aims of reducing speed and increasing torsional moment.

Description

technical field [0001] The invention belongs to the technical field of reducers, in particular to a planetary multistage reducer for a pulverized coal double-roll forming machine. Background technique [0002] In order to facilitate the transportation of pulverized coal and reduce the pollution of pulverized coal to the environment and the loss of pulverized coal during transportation, the coal mining industry extrudes the pulverized coal into a certain shape of block before transportation, advocating the dual realization of environmental protection and economy. [0003] The pulverized coal double-roll forming machine is a new type of coal chemical industry environmental protection energy technology in my country. It belongs to the national eleventh five-year major scientific research and development project. The transmission device for this type has not been implemented before. Contents of the invention [0004] In order to solve the above problems, the present invention ...
