Backlash-Free Hybrid Elastomer Coupling

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a backlash-free hybrid elastomer coupling designed to connect two shafts on a common axis. Each coupling hub is partly coated with a thermoplastic or thermoset material and is joined together using an elastomer, resulting in a secure, form-fitting, and material-bonded connection without play.

Use CasesContent extracted from patent full text and abstract with AI.

• Connecting drive shafts in industrial machinery to transmit torque smoothly
• Automotive drive systems requiring precise, backlash-free power transmission
• Robotic actuators or arms for accurate motion control
• Renewable energy equipment, such as wind turbines, where durable and flexible couplings are needed
• Conveyor systems and packaging machines needing reliable, vibration-dampening connections

BenefitsContent extracted from patent full text and abstract with AI.

• Eliminates backlash, improving precision and control in mechanical systems
• Reduces vibration and noise due to the elastomeric element
• Provides durable, wear-resistant coupling through hybrid (metal-plastic-elastomer) construction
• Compensates for minor misalignments between connected shafts
• Enhances safety and lifespan of connected equipment by reducing mechanical shocks

Patent Abstract

Spielfreie Hybrid-Elastomerkupplung, aufweisend mindestens zwei auf einer gemeinsamen Achse angeordnete Kupplungsnaben (1, 2) mit jeweils einer endseitig angeordneten Aufstandsfläche (10) und von dieser in axialer Richtung abstehenden Mitnahmeklauen (5, 6), wobei beide Naben zumindest teilweise mit einer thermo- oder duroplastischen Beschichtung (3) versehen sind, dadurch gekennzeichnet, dass die Naben über ein Elastomer (4) stoff- und formschlüssig miteinander verbunden sind.
