Pfitzner Performance Gearbox pride themselves on their design, research and development of custom built, high performance, close ratio gear sets, to the highest standard.

The process of gear design is detailed, technical and precise, starting with CAD drawings developed in our state of the art “control room” using the latest software available. These blueprints ensure specifications including tooth count, desired gear ratio and basics like “internal gearbox dimensions”, for your project are incorporated, to produce the strongest, lowest wearing and efficient, tooth profile.

The Pfitzner Tooth ProfileThe custom tooth profile drawings are only the first stage of the process. The next step in the production of a Pfitzner Performance Gearbox is creating unique tools to cut the gear set to exact design. These tools are high-tech, modern and of the highest quality to ensure each gear set is produced with ultimate precision.

A steel billet (a solid piece of pure steel) is then carved, sliced and shaped with absolute precision by our
automated, robotic machinery to accurately mirror the design blueprints. Whether helically or straight cut our gear sets are meticulously created with strength and performance always our goal.

To compliment the unique tooth profile and further enhance strength and reliability Pfitzner Performance Gearbox manufacture a “five dog” design, dog engagement gear set using a distinctive radiused, lightweight dog ring. The Pfitzner dog gear design promotes smooth and rapid gear selection through larger dog engagement pattern, reducing wear with radiused teeth.

Competitor Tooth Profiles

Even some of our most recognised competitor’s, with long term, highly regarded reputations within the high performance field, are still utilising agricultural, technically-basic and inferior design and cutting methods.

Our competitors are manufacturing the same product they have for decades, primarily to avoid re-developing existing machinery, tooling and product designs. These “old school” models are susceptible to wear, pitting and entire tooth breakage.

The Advanced Pfitzner Heat Treating Process

The last phase of the gear set production is heat treatment (case hardening). This is not a new approach to strengthening metal componentry and most clientele of the automotive industry would be familiar with the process of parts being dipped into a heat treating salt bath containing various elements but most importantly carbon.

The “Controlled Atmosphere” heat treatment process Pfitzner Performance Gearbox apply is a more precise and refined method from the original salt bath heat treating. Using a computer controlled atmosphere (furnace) where carbon and other elements are monitored and maintained at optimum levels via highly advanced software and sensors, ensures accurate and efficient heat treating, consistently producing a well hardened and strengthened product for Pfitzner customers.

High temperature levels are produced to attract and infuse carbon onto the surface of the product, penetrating to calculated design depths to harden it. “Rockwell” tests (an international standard of hardness testing) are performed at regular intervals with sacrificial components as a form of ongoing quality control.

Competitor Heat Treating Process

The basic heat treating technique is at times “hit and miss” given element levels fluctuate and more specifically carbon content is “guestimated” producing inconsistencies with this practice. Salt Bath techniques were developed pre the 1950’s and have not evolved since then.

The Pfitzner “Product in Stock” Philosophy

When you are involved in motor sport, you want to know that replacement parts for your race car or team are only as far away as the nearest phone and that includes gear sets. Pfitzner Performance Gearbox produce reliable, high performance, tough gearbox for the motor sport arena, consistently coping with big horsepower, hard driving and extreme loads.

So, when your competitor brand gearbox fails,we have a large range of product in stock to support race and rally clients. There is zero lead time on a considerable collection of our product list because………. it’s on the shelf.
