Description

Service life of the drive unit

 

The drive to the scraper conveyor is installed in the factory shop and is designed to transport bulk cargo, work in two shifts of 8 hours, the load is not changing, the mode is reverse.

 

The service life of the drive is determined by the formula

 

Lh = 365LGKGtcLcKc

 

where LГ = 4 years is the service life of the drive;

 

KG - coefficient of annual use;

 

CG = 300/365 = 0.82

 

where 300 is the number of working days in a year;

 

 tc = 8 hours - shift duration

 

 Lc = 2 - number of shifts

 

 Кс = 1 – coefficient of changeable use.

 

Lh = 365 4 0.82 8 2 1 = 19200 hours

 

 We accept the idle time of the machine unit as 15% of the resource, then

 

Lh = 19200 0.85 = 16320 hours

 

We accept a working resource of 17000 hours
