The reliability of gear drive system
depends upon quality of the component, accuracy of the assembly and the
solid design.
Gear
drives may be classified into various categories on the basis of
work, principles and application of the gears. Based on these
parameters, gear drives are broadly classified as mechanical gear
drives, electric drives, speed changers gear drives, hydrostatic drives
and hydraulic drives.
Mechanical drives are used to provide variable output speed from
a constant speed power source. These mechanical gear drives are
extensively used in automobile industry. Mechanical drives provide
simple control and are cheaper as compared to electrical drives.
A speed changer provides total control over the speed of the
operating system. The actuated speed changers gear drives provide
controlled rate for speed or load change. It is possible to adjust the
speed of the generator simply by adjusting the speed of the operating
system under conditions of single unit, isolated load operation or the
parallel operation with an independent power source.
Hydraulic drives are the gear boxes that connect the power
source and hydraulic pump in hydrostatic drives. The typical application
of fluid drive is to provide speed control for existing pumps or
compressors. These drives have wide applications in heavy material
handling machines like cranes, earth movers, ramp winches, thrusters,
drilling, anchor winches, auxiliary winches, trawl winches, dredging and
more.
