Spiral bevel gears are bevel gears with helical teeth positioned in a 90-degree angle. The teeth are designed with a slight curve to provide better flexibility and traction. Although they can be considered a hypoid gear, they have no offsets, which indicates they will not slip during operation. This ensures smooth, reliable transmission ideal for high-speed, high-torque applications.
The modified helical teeth of spiral bevel gears create dependable, tooth-to-tooth traction that minimizes backlash and prevents the gears from slipping. The gears are carefully spaced to allow lubricants to be spread evenly. The spiral bevel gears in a MITRPAK® gearbox are precisely adjusted via a unique, adjustable locknut design.
Spiral bevel gears are designed for applications that require high speed and high torque power. They can help cut consumer costs by providing long-lasting performance with minimal need for repairs or replacements. With spiral bevel gears, there is no need for offsets and a significantly reduced risk of overheating. Curved teeth and deeper traction between those teeth ensures greater asset availability to improve flexible performance and extend equipment life.
Standard MITRPAK® spiral bevel gear drives have double-shielded, permanently greased, standard-metric-series ball bearings. The gears are made of hardened alloy steel and are contained in an aluminum alloy housing for maximum strength and heat dissipation. They are lubricated for life with Mobilux™EP O. Bonded seals keep lubricant contained to avoid product contamination and reduce unnecessary maintenance or cleaning. MITRPAK® gear drives can also be customized to suit applications that require certain materials. They have multiple flange and body-mounting surfaces. Special materials can be incorporated in shaft extensions and other modifications, which can be designed to suit any unit.
MITRPAK® precision machining reduces backlash in combination with an adjustable locknut, which can precisely adjust the spacing between the gear teeth to minimize noise and provide smooth operation. The reduced backlash from the adjustable locknut also means less maintenance and maximized drive lifespan.
Finding a vendor with qualifications for a high-quality spiral bevel gear can be one of the biggest obstacles for customers. This is why MITRPAK® is able to design changes—even late in the production process. This flexibility and responsiveness reduce risk for OEMs and allow for greater efficiency and productivity.
