How to choose frame models for the four major series of reducers

The selection of the gearbox frame model is mainly based on the size of the gearbox output shaft diameter, installation method, and the force situation of the mixing shaft, while matching the interface form and installation size. The following is a specific guide for selecting the frame for the four series of reducers (F, K, R, S):

1. Determine the frame model based on the output shaft diameter

In principle, the rack model should be selected based on the output shaft diameter of the gearbox. As long as the interface form and installation size match, the rack model can be adjusted up and down within a certain range.

2. Select the type of frame based on the support conditions of the mixing shaft

The frame is divided into four categories: no support point, single support point, and double support point (some materials mention special frames for glass lined reaction tanks). The actual selection needs to be based on the structure and stress characteristics of the mixing container:

3. Installation and adaptation requirements

All racks are generally suitable for vertical reducers.

If the user needs to match other specifications of vertical reducers, the reducer model, specifications, base connection size, and output shaft size must be specified when ordering, so that the manufacturer can adjust the docking plate.

Common rack models include WJ, DJ, SJ and their raised LWJ, LDJ, LSJ, which can be used to install double end mechanical seals.

4. Selection suggestion process

(1) Confirm the reducer series (F/K/R/S) and output shaft diameter;

(2) Analyze the force structure of the mixing device (whether there are additional bearing supports);

(3) Select the corresponding rack type based on the supporting conditions;

(4) Match the installation interface size and communicate with the supplier to adjust the flange if necessary;

(5) Choose the appropriate type of coupling to ensure smooth transmission and easy maintenance.
