First determine what vertical gear reducer, such as cast iron worm gear reducer, aluminum worm gear reducer, gear reducer and so on.
Reducer structure and type of accessories to determine, in understanding the structure of the reducer on the basis of working conditions, the initial requirements to determine the following:
1, reducer transmission series selected, reducer transmission series is based on the working advantages of variable speed drives, by the transmission type, transmission ratio, space position and size requirements.
2, to determine the form of transmission parts, there is no special requirements, the axis as far as possible the use of horizontal layout (such as horizontal reducer). For the two-stage cylindrical gear reducer, the size of the transmission power and the layout requirements to determine the use of expansion or coaxial.
3, the primary type of bearing, the general reducer are used both rolling bearings and sliding bearings, rolling bearing type by the load and speed requirements. Select the bearing should also consider the bearing adjustment, fixed, lubrication and sealing and other issues, and determine the end cover structure.
4, the body structure of the reducer decision, usually in the absence of special requirements, the gear reducer body is used along the gear axis level of the structure, in order to assemble.
5, select the coupling type, high-speed shaft commonly used elastic coupling, low speed shaft commonly used portable rigid coupling
