Boston Gear 30:1 Right-Angle Reducer

This Boston Gear speed reducer provides a nominal 30:1 ratio with a 1.54-inch worm centre distance. It delivers 58 RPM nominal output speed from a 1725-1750 RPM input. The single output shaft exits left-hand facing the input. It is built for industrial machinery that needs compact right-angle power transmission at low output speeds.

Suits drives needing left-hand shaft exit

The unit suits applications requiring a left-hand output shaft and a 30:1 reduction in a right-angle configuration. It handles an overhung load of 300 pounds and produces 208 inch-pounds of torque at quarter horsepower or 277 inch-pounds at one-third horsepower. Builders who need a right-hand shaft exit or a different reduction ratio should look at other models.

30:1 nominal ratio decides fit

The single specification that decides whether this is the right part is the 30:1 nominal ratio combined with the 1.54-inch centre distance. These two figures fix the output speed at 58 RPM and the torque at 208 or 277 inch-pounds depending on input power. Verify both numbers against your design requirements before ordering.

Questions about this item

How much heat or noise does the 30:1 reducer generate when running continuously at 1750 RPM input?

The unit is shipped without oil; you must fill it with the recommended 4ZF30 gear oil (page 3835) before continuous operation to control temperature and noise.

What separate items must I already have to mount and run this 1.54-inch centre-distance reducer?

You need mounting bases (sold separately), the correct 4ZF30 gear oil, a motor that delivers 1725-1750 RPM input, and a driven load compatible with the left-hand output shaft.

Will the left-hand output shaft on this 300 lb overhung-load unit align with my existing right-angle drive flange?

The output shaft exits on the left when facing the input; verify your flange matches that orientation and the 1.54-inch worm centre distance before installation.
