Description

The object of design is a bucket elevator.

This project includes the development and design of a bucket elevator. The explanatory note of the project consists of several chapters, which include the calculation of the drive, the calculation of the elevator, the calculation of the drive shaft, the choice of couplings, the calculations of the tensioning and drive stations, as well as other related calculations. The project also includes five drawings of A1 format: the general view of the elevator, the drive station, the tension station, the chain with buckets and the hopper, as well as the specifications for them.

The task of the project is to develop the design of the bucket elevator. The projected elevator consists of a V-belt transmission electric motor, a two-stage cylindrical gearbox, a tensioning station and chains with buckets attached to them.

The electric motor is selected according to the required power and the number of revolutions. The gearbox is selected by multivariate selection. Bearings are selected as standard according to the calculated reactions in the shaft supports and the specified drive life. The shafts are tested for strength and rigidity. The keyhole and slotted connections shall be checked by calculating the length of the hubs according to the torque transmitted to it.

Transported material – medium-lump crushed stone;

r = 1,8 t/m3 – bulk density of cargo;

Q = 45 t/h – elevator capacity;

H = 20 m – lifting height;

Working conditions – average;

The location of the buckets is closed;

The traction element is a plate chain.
