Abstract

The invention discloses a face gear-type planetary reduction gearbox. A planetary reduction mechanism which is connected between two transmission shafts of the reduction gearbox in a transmission mode comprises two face gear groups, wherein the two face gear groups are rotationally arranged on a gearbox body respectively and formed by coaxially and fixedly connecting internal gear rings which are close to an axis and external gear rings which are far away from the axis; the gear faces of the two face gear groups are opposite to each other; a planetary frame is connected between two corresponding internal gear rings in the transmission mode; a fixed shaft gear is meshed between two corresponding external gear rings in the transmission mode; one face gear group is coaxially connected with a first transmission shaft; and the other face gear group is coaxially connected with a second transmission shaft by the planetary frame. Compared with the conventional cylindrical gear-type planetary reduction gearbox, the face gear-type planetary transmission mechanism has the advantages of high transmission ratio, compact structure, good load balancing effect and the like, and is stably operated, and the carrying capability of the unit gearbox of the face gear-type planetary transmission mechanism is 20 percent higher than that of the cylindrical gear-type planetary reduction gearbox.

Description

technical field [0001] The invention belongs to the technical field of planetary gear transmission, and mainly relates to a planetary gear reduction box. Background technique [0002] The planetary gear reducer has the advantages of compact structure, large transmission power, high load capacity, large transmission ratio, input and output coaxial lines, etc. It is widely used in metallurgy, mining, cement, automobile, lifting, machine tool, chemical industry, electric power, textile, Instrumentation, food, power generation and other machinery. However, the existing planetary gear reducer basically uses an involute cylindrical gear planetary transmission mechanism, which mainly includes an internal gear and a sun gear arranged coaxially. Assembled on the planet carrier, the planet carrier and the sun gear are respectively connected with transmission shafts. This kind of involute cylindrical gear planetary transmission mechanism has a relatively complex structure and a large...
