Stober releases new PS two-speed gearbox
November 30, 2016 by Manufacturing AUTOMATION
Nov. 30, 2016 – Stober Drives has introduced its PS two-speed gearbox, which it says has the ability to generate both high speed and high torque, and is ideal for lathes or machining centres.
The 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. Customers can also choose between two different output types — shafted and flanged — with three different versions of each utilizing a short, medium, or long output. Three different bearing options for the output means even more customization options for an application, notes the company. 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.
