Polimak Ltd. has over 25 years of experience
in custom gear and gearbox manufacturing. The production
capabilities range from a gear of 10 mm. in diameter up to a
gear over 4000 mm. in diameter. We have been manufacturing
drive systems for all major industries, including steel,
metal working, chemical, paper, cement, rubber, mining,
agricultural, waste water treatment and material handling.
We also provide a breakdown service to keep your application
working. No matter how special the application is, Polimak
Ltd. assures quality product solutions. As a full-service
gear supplier, Polimak Ltd. prides itself on superior
customer service, on-time delivery, competitive pricing and
superior quality. We have the ability to produce the
following types of precision gears to meet your
specifications:
|
Spur Gears
Spur gears are one of the most used gears in the
industry. In spur gears, tooth profile is parallel to the rotation
axis. Some application examples are tower rotation of vinches and
industrial machinery |
 |
Helical Gears
The tooth profile have an angle with rotation axis
in a helical gear. Helical gears are more silent and can carry more
load than spur gears. They are used in gearboxes of vehicles, gear
reducers and machinery. |
 |
Herringbone Gears
Herringbone gears (also known as double helical
gears) have two helical gears with opposite angles placed in the
same body. They are generally used in rolling mills. |
 |
Straight Bevel
Gears
Bevel gears enable a change in the axes of
rotation of the respective shafts, commonly 90° |
 |
Spiral Bevel Gears
Spiral bevel gears have the same functionality
with straight bevel gears. More than that, these gears are more
silent and offer more load carrying capacity with higher rpm |
 |
Internal Gears
In internal gears, the gear profile is at the
inner side of ring. They are generally used in planetary gear
systems.
|
 |
Rack and Pinion
Gears
Rack and pinion gears are used to convert
rotational motion to linear motion. They are generally used in
vinches, routers and sliding gates. |
 |
Involute Splines
Involute spline gears are used to transfer
rotational motion in the sam concentric axis. The spline gear is
inserted in to an internal spline gear to transfer rotation. |
 |
Spline Shafts
Spline shafts are used to transfer rotational
motion for long distances lik 3 - 4 meters. They are generally used
in vehicles between shifting georbox and differential gearbox. |
 |
Worm Gears
In worm gears a screw with parallel helical teeth
mates with a modified tooth profiled helical gear. The worm is
always the driving gear. This gear style will self-lock if power is
lost to the drive (worm). It doesn't work if the pinion is powered.
This is why worm gears are used in elevators. |
 |
Planetary Gears
They are also known as epicyclic gears. An
internal gear, a small gear at the center of internal gear and
generally 3 gears between them are found in planetary gears. They
are generally used in construction machinery and wind turbines. |
 |
Chain Sprockets
A sprocket is a gear or wheel with metal teeth
that meshes with a chain or track. They are used in some machinery
and bicycles. |
 |
Timing Belt Pulleys
Timing belt pulleys are used when timing and silence required. They
also work oil-free. Timing belts are used in vehicles, medical and
food machinery. |
 |
Pump Gears
Pump gears are used to pump liquids
like hydraulic oil and fuel.
|
 |
|
Trapezoidal threads, gear threads,
injection screws, monopump rotors, drilling pipes, drill casing
pipes are some of the applications of threads and screws |
