Zero-Max's Newest Couplings Designed for Servo Application with High Reverse Load and Precise Positioning
According to the company's press release, the new couplings feature zero backlash and higher torsional stiffness required in today's servo motor applications with high reverse loads and precision positioning requirements.
Manufactured of ROHS-compliant materials containing no banned substances, the couplings are designed with 304 stainless steel disc packs and 7075-T6 aluminum hubs and center members. Its design provides high torsional stiffness with low inertia to avoid system resonance in all types of servo systems, according to a company press release.
ServoClass couplings handle system speeds up to 10,000 rpm and have a torque rating range from 4.43 in.-lb. (0.5 Nm) to 530 in.-lb. (60 Nm). A system designer can select from 16 sizes and from combinations of inch and metric hub bore sizes to meet exacting servo drive requirements. All models and sizes feature clamp style mounting hubs with recessed, corrosion-resistant clamping bolts.
As the application cycle times become faster, the wind-up in beam couplings or the fragile nature of the bellows couplings become more of a serious problem. The robust design of the Zero-Max ServoClass® Coupling performs reliably in precision, high speed servo applications.
The couplings are suited for use in most high precision applications including packaging machines, pick-and-place systems, printing machinery, machine tools and most systems utilizing servomotors.
