SHUTON·IPIRANGA Applied Engineering Department offers its customers comprehensive advice for the selection of the most appropriate ball screw and optimal use for each application, studying the different solutions. There are two possibilities to carry out the studies: - Calculate the performance of a specific ball screw with a given set of bearings, motor and transmission system, getting result for: · Ball screw fatigue life · Table or head feed speed · Ball screw critical rotation speed and speed limit · Deflections or radial deformations, and advice on rests · Estimated noise level [ dB ] · Expected temperature increase · Necessary pretensioning force in the event of a pretensioned shaft · Grease amount or oil and recommended lubrication · Maximum supported force and recommended limit · Approximate drive natural frequency and estimated gains of position kv and speed kp links · Required table acceleration and motor torque · Relationship between inertias and servo control response · Ball screw force and preload torque · Rigidity of nut and entire ball screw - Calculate which drive (ball screw, motor, transmission system, etc.) is best suited to achieve desired speed, acceleration, rigidity and fatigue life. One of the most innovative and important aspects of the ball screw study is its provision of approximate motor control values, that is, closed control loop position kv and speed kp gains. These values are extremely important for getting an idea of a machines dynamics. Two or more potential drives can be compared during the design phase of the machine, revealing the drive component that limits the machine’s dynamic behaviour* (ball screw, bearings, pulleys, etc.). SHUTON-IPIRANGA Engineering Service team has broad experience in the study of different applications keeping close collaboration with leading manufacturers in different application fields. Technical application forms can be requested at https://www.shuton.com/en/ engineering-service or through your closest Shuton-Ipiranga contact. Engineering Service * The programme cannot know if it really is the drive that limits machine dynamics, as it has not data about the structure. If it is the structure that is the limiting factor, improvements to any of the drive elements will have no effect. ‘Technical Form’ ‘Study report’ v.5 ENTERPRISE INFORMATION ENTERPRISE: PHONE: MODELMACHINE: FAX: DRAWING /AXI: E-MAIL: CONTACT: CITY: tomove from one cell to the other press ‘tab’  on the left of the keyboard CLARIFYINGDRAWINGOFTHEBALLSCREW’SLENGTHS l e : Security length. l hr : Thread length of the ballscrew.
