Stober Offers PS Two Speed Gearbox
Stober offers two different output types: shafted and flanged, with three different versions of each utilizing a short, medium, or long output.
The Maysville, Kentucky gearbox manufacturer has introduced a new gearbox for the machine tool industry.
The PS Two Speed gearbox features two different options, from a direct drive to customer ratio choice. The 1:1 ratio direct drive can be used for high-speed cutting up to 10,000 rpm. The customer can choose from two ratios, 4:1 or 5.5:1, that are capable of turning at 7,000 rpm. This allows the customer to use a 1:1 ratio for low torque high speed cuts and the 4 or 5.5:1 ratio for high torque lower speed cuts.
"This gearbox was designed for easy motor mounting," said Tyler Mattingly, applications engineer at Stober. "Simply slide the motor shaft into the input coupling, bolt the motor to the gearbox, and torque the coupling accordingly."
Stober offers two different output types: shafted and flanged, with three different versions of each utilizing a short, medium, or long output. This allows Stober to customize the product for customer applications, he added.
Three different bearing options for the output means even more customization options for an application. There is an option for a standard deep groove ball bearing; an angular contact bearing; or cylindrical roller bearings, depending on the loads produced by a customer application. There are two different sizes to fit a variety of motors: the PS 25 and the PS 30. Utilizing these design features, this family of gearboxes is capable of up to 2,200 Nm worth of torque.
