Metric Spur Gears


Metric spur gears are categorized into modules ranging from module size 1 through module size 8. The common metric spur gears that we stock are manufactured out of a high quality C45 (C1045) steel for strength and durability. When selecting a metric spur gear it is imperative to properly size the gear based upon load capacity (this rule applies to new applications/ application design). The allowable strength/ bend strength of a metric spur gear is also known as the allowable tangential force at the pitch circle, this relates to the allowable load on the tooth and bending stress within the root of the gear tooth resulting from the load. For figuring this data use the rolling stress load on the tooth σ = 589 N/mm2 and allowable bending stress σ = 200 N/mm2. Note we also have additional formulas within our "Selection Formulas" tab below. For any metric spur gear application it is also imperative to utilize proper lubrication, application speeds that are less than 0.5 m/s can get by with grease but any speed equal or greater than 0.5 m/s should use our Open Gear Oil for proper operation and gear life. For additional information or quotations please contact our customer service team at (407) 347-3519 or email sales@usarollerchain.com and we will be happy to assist you!

Service factors are important to consider when making a gear selection and for general application use. The below chart shows the most common and basic service factors to consider with metric and standard gear applications.

The below charts are for gear formulas, note that metric gear ratings are in metric units. Standard gear formulas and HP-Torque formulas are to the left and formula conversion factors are on the "Conversion Factors" tab. Precautions should be taken and close attention should be diligent to ensure unit conversions are accurate.
