for the course project on Machine Parts

design a plate conveyor drive station (see Atlas

structures "Transporting machines" Spivakovsky A.O.S. and others.

publishing house "Engineering," 1992).

In the design of the drive use two-stage

cylindrical reduction gear with bifurcated slow-moving stage by type,

shown in Fig. 1, p. 146 Atlas of structures "Machine parts" under

editors D.N. Reshetov, publishing house "Mechanical Engineering," 1979.

Design Input:

the load on the conveyor is constant; starting moment value is assigned

by technical characteristic of the selected electric engine; t = 10 years; Kg = 0.4;

Ks = 0.33; tmax=1.05c; dimensions of traction chain - GOST 58881, dimensions of sprockets -

GOST 59281; traction force F =6kH; circuit speed v = 0.9m/s; circuit pitch P = 80mm; number of sprocket teeth z = 10.

In the graphic part of the project, develop:

general view of the drive; 2) reduction gear box; 3) coupling; Detail working drawings.
