4 Integrated power translation packages 4 As a leader in manufacturing racks, pinions and gearheads, MIJNO has extensive experience to share with you. Among our ranges of standard or custom racks and gearheads we very likely have products that will go well with your application. If we don t, then we can still design it and make it for you! called ROTAXE, developed for high speed applications. This improves smoothness and reduces wear (more information on com). You ll hear the difference. «Zero backlash» racks and pinion systems. Our products can be assembled via a large variety of combinations ; however, some choices optimize the application. Just call us or send us an and we will suggest the best packages of gearhead, rack and pinion to optimize your machine. We only need to know your choice of motor, the acceleration, linear speed and strength you need, as well as your requirement for angular or linear precision - we ll do the rest! We can securely fasten the rack pinion on a gearhead shaft upon request and deliver the whole set (gearbox, gear, racks that are guaranteed to work together). The particularly quiet and precise running of gearbox-pinion-rack sets is ensured by: The use of precision ground teeth in our gearboxes according to DIN class 6 to 5 accuracy. Rack and pinions with ground teeth including a proprietary modification of the tooth profile

5 Precision gearboxes standard features 5 Our expertise is gearing - All our satellite gears are case hardened to HRC and ground to class DIN 6 to 5 - AGMA 12 to All our satellite gears feature MIJNO s exclusive Rotaxe tooth profile modification. This reduces friction, increases lifetime and offers quiet operation. - All key components are manufactured in house, under MIJNO s strict quality management. - All bearings are oversized and purchased from the world s most reliable suppliers. - All gears rotate on full-complement needle bearings instead of caged needle bearings for longer life and greater load capability. - All our backlashes are guaranteed for rated gearhead life. - All our torque ratings are conservative, calculated to provide the longest lifetime possible. Lubrication Gearhead Types lubricated with grease : MRP / MNT 065 / MSK / MRA 065 The above gearheads are delivered ready to mount onto your motor, lubricated with grease specifically chosen to ensure maximum performance. MIJNO installs a KLÜBER (brand) grease, which provides a nominal lifetime of 15,000 hours without grease change. Gearhead Types lubricated with oil : MNT / MRA (right angle section has grease) / BDB The above gearheads are delivered ready to mount onto your motor, lubricated with a KLÜBER oil. This synthetic oil has been selected to optimally lubricate the gears, bearings and shaft seals. The oil contemplates a lifetime of to 30,000 hours. Gearheads are oil lubricated for horizontal mounting position unless otherwise specified. Also on request, we can lubricate your gearhead for multi-position mounting. Assembly to your motor is quickly accomplished by the integrated, self locating input pinion. A two-screw clamping coupling secures it to the motor. Can be mounted to any motor appropriate for the gearhead torque ratings. The price includes most motor adapter flanges when needed. Unique flanges can be manufactured. General lubrication vs. life information : The nominal lifetime of our gearheads generally depends on the duty cycles of the application. For an operating temperature above 90 C or under -20 C, special lubrication is recommended. For unusual environmental conditions (extreme temperatures, vacuum conditions, nuclear environment, food processing etc), please contact us. VITON seals are employed in all gearboxes to resist heat and provide long life while preventing leakage.

11 Standard & custom racks and pinions 11 MIJNO has designed and manufactured precision racks since 1972 and has acquired an extensive knowledge to share with you. Based on this 35 years experience we have designed five ranges (categories) that offer proven, coherent, efficient solutions. We have found the following 5 ranges to be popular with our customers. RANGE & TYPICAL APPLICATION FIRST: Precise translation of light loads. CLASSIC: Fast and precise translations of light loads over several metres. GOLD: Fast and precise translation of heavy loads over long distances. PLATINIUM: High precision, silent and fast positioning of heavy loads over long distances, frequent reversals. CARAT: Highest precision, silent and fast positioning of heavy loads over long distances. However, if your preferred choice cannot be found in those ranges, do not hesitate to ask for your customized solution. Our R&D department will be happy to analyze your application and suggest the best option for it (steel, module, surface treatments, precision class, geometry...). Our capabilities: Quantities from 1 to 1000 units.

18 18 One of our many areas of expertise is the production of middle-size annual quantities of precision gears for the defense, aerospace or machine-tool industries according to customer drawings or specifications. Our knowledgeable methods department continually searches for innovations in tools, machines, treatments and processes. It is supported by a large variety of 120 company owned machine-tools. The different machines enable us to perform, in house, all manufacture of complex profiles requiring a high level of precision. Our production is organized in strategic task groups, each of them masters a specific core-competency (turning, CNC, gear tooth cutting, grinding, etc.). Many of our machines are connected to our CAM system, ensuring the repeatability of our quality by direct integration of your drawing into our system. We are located in the heart of a high-tech manufacturing region. We regularly invest in local subcontractors to benefit from their expertise (heat treatment, surface treatments, CNC ). We consider that their technology is an asset in our quest for unique know-how and problem solving for our customers. We employ most nondestructive inspection technologies (nital tests, eliquation, magnetoscopy ). Dimensional inspection of gear tooth profiles is performed in a Höfler/ Zeiss gear inspection center running on the latest inspection software available. These techniques enable us to provide you with detailed reports on every aspect of the parts we manufacture.

19 19 Gears For over 90 years we have refined an extensive knowledge of defining manufacturing processes most appropriate to your gear s complexity. As a result, upon delivery, your part will conform the first time to specifications.
