Global Helical Gear Reducers Industry 2016 Market Research ReportChapters11 Industry Overview of Helical Gear Reducers1.1 Definition and Specifications of Helical Gear Reducers1.1.1 Definition of Helical Gear ReducersHelical gear reducer is a kind of gear reducer which is produced with the use of helical gears. Helical gears are cylindrical gears whose teeth are not parallel to the axis of rotation. Helical gear reducers run smoother and quieter than other types of gear reducers and are able to carry heavy loads efficiently.Figure Picture of Helical Gear ReducersSource: QYR Machinery Equipment Research Center, Oct 2016Figure Internal Structure of Helical Gear ReducersSource: QYR Machinery Equipment Research Center, Oct 20161.1.2 Specifications of Helical Gear ReducersThere are various models of helical gear reducers produced by different manufactures available in the market. Here we take the in-line helical 800 Series from Boston Gear as an example to have a brief sight of the specifications of a helical gear reducer.Table Product Specifications of Helical Gear Reducers from Boston GearProduct PictureSpecificationsSource: Boston Gear, QYR Machinery Equipment Research Center, Oct 20161.2 Classification of Helical Gear ReducersTable Classification of Helical Gear ReducersClassificationDescription1Parallel-axis helical gear reducerIn parallel-axis helical gear reducers, the two opposite-hand gears provide quiet operation and high load capacity. These helical gears must be of opposite hands.2Perpendicular-axis helical gear reducerIn perpendicular-axis helical gear reducers, two same-hand gears transmit energy through a 90° angle. The limited tooth contact of this configuration constricts work load. This type of helical alignment is comprised of two same-hand gears.Source: QYR Machinery Equipment Research Center, Oct 20161.2.1 Parallel-axis Helical Gear ReducerFigure Parallel-axis Helical Gear ReducerSource: QYR Machinery Equipment Research Center, Oct 20161.2.2 Per
