Stepless speed regulation device of marine generator and marine generator

Abstract

The invention discloses a stepless speed regulation device of a marine generator and the marine generator. The stepless speed regulation device comprises a driving pulley assembly, a metal band, a driven pulley assembly, an ordinary gear train speed reducer and a planetary mechanism. The driving pulley assembly is connected with the driven pulley assembly through the metal band. The ordinary gear train speed reducer comprises a first gear pair and a second gear pair, wherein the first gear pair is connected with the second gear pair. The first gear pair is connected with the driven pulley assembly, and the second gear pair is connected with the planetary mechanism. The planetary mechanism comprises a sun gear connected with the driving pulley assembly, an inner planet gear meshed with the sun gear, an outer planet gear meshed with the inner planet gear, a gear ring meshed with the planet gear and used for outputting power, and a planet carrier used for supporting the inner planet gear and the outer planet gear, wherein the planet carrier is connected with the second gear pair. Variable-rotating-speed input of a driving unit is converted into constant-rotating-speed output, the driving unit can directly drive the generator to generate electric power, and energy consumption and cost are reduced.

Description

technical field [0001] The invention relates to a stepless speed regulating device, in particular to a stepless speed regulating device of a marine generator and a marine generator. Background technique [0002] Marine generators are widely used on fishing boats. The drive unit (for example, diesel engine) needs to complete other tasks while generating electricity. Therefore, the speed of the drive unit needs to be variable and adjustable, and the input speed of the generator is relatively low when generating electricity. Constant, so it is necessary to have a dedicated power generation auxiliary machine as the drive unit of the generator, which leads to the complexity of the structure of the entire power system, and increases the energy consumption and purchase cost of the power system. Contents of the invention [0003] The purpose of the present invention is to provide a stepless speed regulation device and a marine generator for a marine generator, so as to solve the t...
