Speed reducer special for efficient granulator

Abstract

The invention aims at providing a speed reducer special for an efficient granulator. The speed reducer comprises a speed reducer box body. A connecting shaft, a second-level intermediate shaft, a third-level intermediate shaft, a third-level gear shaft and a hollow shaft are sequentially arranged in the speed reducer box body in parallel. An input small gear is installed on the connecting shaft. An intermediate small gear and an input large gear engaged with the input small gear are installed on the second-level intermediate shaft. An intermediate large gear engaged with the intermediate small gear is installed on the third-level intermediate shaft. A third-level large gear engaged with the intermediate large gear is installed on the third-level gear shaft. An output large gear engaged with the third-level gear shaft is installed on the hollow shaft. The speed reducer box body comprises a bottom cover and a top cover covering the bottom cover. The two ends of the connecting shaft, the two ends of the second-level intermediate shaft and the two ends of the third-level intermediate shaft are supported on the bottom cover of the speed reducer through deep groove ball bearings. The two ends of the third-level gear shaft and the two ends of the hollow shaft are supported on the bottom cover through tapered roller bearings.

Description

technical field [0001] The invention relates to a reducer, in particular to a special reducer for a high-efficiency granulator. Background technique [0002] With the rapid consumption of fossil resources and the continuous deterioration of the ecological environment, countries around the world, especially major powers, have made the development of new energy and renewable energy the focus of a new round of industrial development. Biomass, as the only renewable resource that can convert gas, liquid and solid fuels and has a two-way cleaning effect, has attracted widespread attention from most countries in the world. During this process, pellet machines for the production of biomass pellets also began to play an important role in the market. The reducer is a main power and transmission mechanism of the granulator, but in the actual production process, due to the limitation of the maintenance, installation and use environment of the granulator, most of the reducers used in th...

Problems solved by technology

The reducer is a main power and transmission mechanism of the granulator, but in the actual production process, due to the limitation of the maintenance, installation and use environment of the granulator, most of the reducers used in the granulator have high energy consumption and low energy consumption during the transmission process. efficiency

In addition, because the existing granulator is mainly set up with a welded base, which wraps the right-angled shaft gearbox in the inner cavity, due to the small heat dissipation area of ​​the spiral bevel gear input seat and the surface of the whole box, an
