Double-planet double-output gear drive mechanism

Abstract

The invention discloses a double-planet double-output gear drive mechanism which comprises a bevel pinion, wherein the bevel pinion is connected with external motion and force; the bevel pinion is connected with a bevel gear wheel so as to form a first level right-angle cone gear drive mechanism, and the bevel gear wheel is connected with a first level sun wheel; the first level sun wheel, a first level planetary wheel, a first level annular gear and a first planet carrier are connected so as to form a first level planet gear mechanism, and the first level annular gear are fixedly connected with a second level sun wheel; the second level sun wheel, a second level planetary wheel, a second level annular gear and a second level planet carrier are connected so as to form a second level planet gear mechanism, and the second level planet carrier is fixed; the first level planet carrier is fixedly connected with the second level annular gear; and the motion and the force passes through the first level planetary wheel mechanism and then are shunted, one part is outputted through the first planet carrier, and the rest is outputted through the first level annular gear, the second level sun wheel, the second level planetary wheel and the second level annular gear. The gear drive mechanism provided by the invention has the advantages of improving the carrying capacity of a reducer, and decreasing the volume and the weight.

Description

technical field [0001] The invention relates to the technical field of main drive reducers for vertical mills, in particular to a double planetary double output gear transmission mechanism. Background technique [0002] The traditional structure of the vertical mill reducer is generally divided into three structural forms: two-stage transmission structure, three-stage transmission structure or double planetary structure. The two-stage transmission structure, that is, through the first-stage right-angle bevel gear transmission and the first-stage planetary gear mechanism with the input shaft vertically upward, realizes deceleration, direction change and power transmission; the three-stage transmission structure adds a stage to the original two-stage transmission structure. Parallel shaft gear transmission distributes the torque transmitted by one-stage large speed ratio and large-sized bevel gear pairs to two-stage gear transmission; the double planetary structure is one-stag...

Problems solved by technology

[0003] Due to the above three forms of transmission results, the internal gear pairs are all in series structure, and there is only one output end. Therefore, when transmitting high power, the size of the gear pair and the body is very large, which brings a lot of inconvenience to processing, assembly, installation, use, etc.
