Permissible surface compression values are given for different material combinations.
Specifications and Parameters
Technical specifications related to torque, power, and speed for mechanical components are outlined, with measurements in Newton-meters and kilowatts.
Ambient Temperature and Duty Cycle
For ambient temperatures above 20°C, the duty cycle must be reduced according to a specified table.
Tooth Profile and Axial Play
Tooth profile play and axial play are discussed, affecting positioning accuracy.
Lateral Play
Lateral play occurs in the basic design due to play between the spindle and guide ring.
Efficiency of Jack Elements
Formulas and tables for calculating the efficiency of gearboxes and spindles with grease lubrication are provided.
Buckling Force
Permissible buckling force is detailed with diagrams for preselection of spindles.
Power Tables
Power tables for jack elements with TR spindles are provided, detailing power requirements for various loads and speeds.
Permissible Lateral Forces on the Spindle
Permissible lateral forces depend on spindle length, diameter, and axial force, allowed only with a second guide ring.
Critical Spindle Speed
Relevant for the travelling nut version, considering spindle diameter, length, and bearing arrangement.
Ballscrew (Basic and Travelling Nut Versions)
Details on cylindrical and flange designs, lubrication, and materials used, with emphasis on reduced backlash and selective ball assembly.
Technical Specifications
Detailed technical specifications for ball screw nut models, including load ratings and axial play.
