Abstract

The invention discloses a one-input multi-output coaxial planet gear type gearbox. The one-input multi-output coaxial planet gear type gearbox comprises at least two planet gear mechanisms, wherein each of the two planet gear mechanisms comprises planet gears, planet gear connecting flanges, a planet carrier, planet shafts, an inner gear ring and an output shaft; a first transmission gear is arranged on the output shaft; a second transmission gear is arranged on the output shaft of a first-level planet gear mechanism; the output shafts of each of a second-level mechanism and other planet gear mechanisms adopt a hollow cylinder-shaped or pipe-shaped structure; the output end of the output shaft of the planet gear mechanism of the former level penetrates through the output shaft of the planet gear mechanism of the latter level; when power of level-III or above is needed to be output, a third transmission gear is arranged on the output shaft of the planet gear mechanism of the former level. The double power output or multiple power output adopted by the gearboxes is coaxial output, and the gearboxes have the characteristics of compact structure, small size, low noise, large torque, larger reduction ratio, and the like.

Description

technical field [0001] The invention relates to a gearbox, in particular to a one-input multi-output coaxial planetary gear gearbox and an aerator gearbox. Background technique [0002] The gear box is an important transmission part of the aerator. The working parts of the aerator are driven by the gear box to achieve the purpose of increasing oxygen and improving water quality. With the development of the aquaculture industry, various multifunctional compound aerators are constantly appearing. The development and production of multifunctional aerator gearboxes is one of the problems that aquaculture machinery needs to solve urgently. However, limited by the structural design of the existing gearbox, there are often problems such as troublesome space installation, single power output, too small radial force, and non-concentric transmission parts, which lead to unstable operation of the aerator and generated Larger noise, poor safety performance and other issues.
