Gears, Gear Boxes

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 1500 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.

 

 

Spur Gear

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.

 

Helical Gear

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.

 

Herringbone Gear

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.

 

Spiral Bevel Gear

Internal Gears

In internal gears, the gear profile is at the inner side of ring. They are generally used in planetary gear systems.

 

Inner Ring Gear

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.

 

Involute Spline Gear

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.

 

Spline Shaft

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.

 

Worm Gear

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.

 

Planet Gear

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.

 

Chain Sprocket Gear

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.

 

Timing Belt Pulley

Pump Gears

Pump gears are used to pump liquids like hydraulic oil and fuel.
