3 Gearheads: Application Solutions Stealth Gearmotors for Factory Automation APPLICATION CHALLENGE The customer manufactures machines for gluing, fill, sealing and diverting of food containers for the food-processing industry. The motor and gearhead needed to be mounted above the food plane. Certain modifications had to be made to the gearhead to make it safe in this environment, as well as making the gearhead able to withstand frequent washdowns. Design Considerations Gearhead Lubrication must be USDA food grade approved in case of incidental contact to food. Gearhead Sealing to prevent any leaking as well as prevent any ingress of the fluid during washdown. Gearhead Finish special FDA-approved finish must be used, making it very durable and resistant to chipping, oxidizing or rusting. Gearhead Output Shaft stainless steel to prevent any rust from developing and contaminating the processing food. Stealth Gearheads on a Bottling Application APPLICATION CHALLENGE The manufacturer of high-speed milling machines used in the aerospace industry. These milling machines are becoming more commonplace in the aerospace and automotive industries because it allows large structural components to be machined from one piece, where before they were assembled from many smaller subcomponents. In high-speed milling, spindle heads are operating at speeds ranging from 18, to 4, RPM, so that the cutting is above the resonant frequency of the machine. Because of this, many characteristics become more critical than in standard machines. The extremely large size of the spindle head also posed problems for the customer in trying to keep it accurately positioned during the milling stage. Low Stiffness The spindle head was moved rotationally by 2 bull gears, driving a large ring gear. Because of the system characteristics, it was difficult to keep the spindle head absolutely stiff during the milling process. The problems associated with low stiffness are: 1. Poor surface finish 2. Accuracy errors 3. Excessive tool chatter 4. Reduced tool life Stealth Gearheads on High-Speed Milling Machines APPLICATION CHALLENGE The manufacturer of high-performance plastic extrusion equipment. They needed a drop-in replacement gearhead for an existing worm gearbox used with their motor without having to alter the design of their machine. The gearhead/motor combination is being used to drive the machine's rollers. It controls the speed at which the plastic is extruded into high-quality plastic sheets. The smoothness of the rollers is critical to the quality of the plastic sheets being produced. High Transmission Error and Velocity Ripple The customer used worm gearheads to control the rollers. Worm gears exhibit a sliding action of involute gears instead of a rolling action, contributing to the lack of smoothness of the machine rollers. Due to the high transmission error and velocity ripple from the worm drive, the rollers operated at differing speeds. This produced small lines and imperfections on the plastic sheets, rendering it unusable. 186 High Wear and Low Efficiency The high level of rubbing (sliding action) between the worm and wheel teeth in the worm gearhead caused a high gear-tooth-wear rate and a lower efficiency (7%) than other major gear types.

4 Parker Bayside SOLUTION PS115-1-F1 Stealth PS planetary gearhread with standard food grade option. The F1 designation provides the gearhead with standard modifications: special lubrication, viton seals, special finish and a stainless steel output shaft. Since this food grade modification is a standard option, delivery is only one week over the standard (typically one week) gearhead lead time. Note: Similar standard modifications exist for vacuum, clean room, high temperature and radiation. Parker Bayside SOLUTION (1) Stealth PS Gearhead and (1) Stealth RT MultiDrive (throughbore) Gearhead The above Stealth gearhead products were used in combination to provide the required 12:1 ratio. The result was high-quality plastics sheets that exceeded the customer's specifications. The Stealth's all-helical planetary design (HeliCrown Gear Tooth) features extremely high gear tooth accuracy, minimizing transmission error and velocity ripple. The Helicrown design features extremely high efficiency (98%) while minimizing tooth wear by providing a pure rolling action. Parker Bayside's Plasma Nitriding heat-treating process further heightens the gear tooth's wear resistance. The Stealth MultiDrive gearhead features a space-saving thru-bore (hollow shaft) option, eliminating compliance that occurs when coupling a gearhead shaft to the rollers being driven. This solution can be used for a variety of applications, including: 1. Packaging 2. Food 3. Semiconductor 4. Automotive 5. Medical Parker Bayside SOLUTION (2) Stealth PS142 Helical Planetary Gearheads The above Stealth gearheads were used in tandem to create a stiff platform for the spindle machine head. One gearhead, acting as the master, and the other as the slave, were attached to the bull gears to simultaneously turn the ring gear that positioned the machine head. While the master gearhead moved the ring, the slave was taking up the backlash. In this way, the precision gears allowed for the spindle to be moved accurately, while the two gearhead combination maintained maximum system stiffness. Parker Bayside's Stealth PS gearhead features an all-helical planetary gear design. Helical gears have a much higher tooth-contact ratio and greater face width than straight-spur gears, providing higher loads, smoother tooth engagement and quieter operation. The Stealth's HeliCrown Gear Tooth design provides extremely high gear tooth accuracy, while minimizing tooth wear. Parker Bayside's Plasma Nitriding heat-treating process further heightens the gear tooth's wear resistance. This solution can be used in the aerospace and automotive industries Toll Free Fax (877) SERV99

7 Stealth PS Advanced Series Get the Helical Advantage! Stealth Advanced in the PS / RS Models incorporates the latest enhancement in gearhead technology: Latest technology in seals reduce heat and wear Oil lubrication reduces, friction and operating temperature Front output seal cover captures and protects output seal Helical Planetary Design - Helical gears have more tooth contact and greater face width than spur gears. This results in higher loads, smoother tooth engagement, quieter operation and lower backlash. HeliCrown - Parker Bayside developed the HeliCrown gear tooth to further optimize Stealth s performance. Since most vibration occurs at the entry and exit points of a gear tooth, HeliCrown eliminates metal only in these areas, without sacrificing gear strength, producing a quieter and stronger gear. Plasma Nitriding - Parker Bayside s in-house Plasma Nitriding process results in an ideal gear tooth. The surface is very hard (65 Rc) and the core is strong, but flexible (36 Rc). The result is a wear-resistant gear tooth that can withstand heavy shock, ensuring high accuracy for the life of the gearhead. ServoMount - Parker Bayside s patented ServoMount design features a balanced input gear supported by a floating bearing. This unique design compensates for motor shaft runout and misalignment, ensuring TRUE alignment of the input sun gear with the planetary section and allowing input speeds up to 6, RPM. ServoMount ensures error-free installation to any motor, in a matter of minutes Front Output Seal Cover Completely captures and protects output seal and allows in-field seal replacement. Output Wave Seal Technology Creates a hydrodynamic film between seal and shaft and reducing heat and wear.
