Maintenance

Grinding Heads Drive System

The Husqvarna PG 530 comes equipped with Dual Drive Technology™. As the grinding discs are driven by the large motor via an internal belt, and because the belt is sealed inside the machine, there is no mainte- nance regarding this drive system until a major service (belt and bearing replacement) is due. This is typically following 12-36 months of operation.

Planetary Drive System

The second component to the Dual Drive Technol- ogy™ system is the planetary head drive system which is powered by the secondary or small motor and gearbox arrangement. This system is on the outside of the machine and will require routine maintenance.

The planetary drive system can be seen as illustrated diagram 1.

Diagram 1. Planetary Drive System

Beneath the gearbox and concealed by the mounting brackets and machine cover, there is a planetary drive sprocket situated on the output shaft of the gearbox.

This planetary sprocket engages with the chain ring (also located beneath the machine cover) and together form the main drive mechanism for the plan- etary drive system. This system is a dry system (i.e. it is not required for there to be lubrication between the planetary drive sprocket and chain ring), to allow any dust that may come into contact with the chain ring to fall back out again.

IMPORTANT!

Lubrication of this system will cause dust to build up in chain ring and drastically shorten the life of both the chain ring and planetary drive sprocket.

1. Planetary seal

The chain ring and planetary drive sprocket are located beneath the cover of the machine, however on the outside of the machine, there lies the potential that they can be exposed to dust and other debris created during the grinding process. In order to prevent this as much as possible, a planetary seal has been installed to stop dust and other particles from coming into contact with the planetary drive mechanism.
