What are gears for power transmission? Technical summary for design engineers
Updated February 2020 || The function of a gear is to mesh with other gears to transmit altered torque and rotation. In fact, gearing can change the speed, torque and direction of motion from a drive source. Geometry & general gear design When two gears with an unequal number of teeth engage, the mechanical advantage […]
What are Retaining Rings? Summary for Motion Engineers
Retaining rings are fasteners that hold together components on a shaft when installed in a groove. There are three main types of retaining rings; tapered section, constant section and spiral. Tapered section rings are characterized by their decreasing thickness from the center of the ring out to the ends. These rings can be mounted either […]
What are Flexible Couplings? Summary for Motion Engineers
Couplings join together two shafts as a way of transmitting power from one to the other. It is part of the drivetrain which may include other power transmission components such as lead screws or ball screws, gearboxes, belts and pulleys or chains. There are two fundamental types of couplings; rigid and flexible. Rigid couplings are […]
What are torque limiters? Technical summary for motion engineers
Updated November 2018 by Lisa Eitel || Torque limiters protect equipment or loads from excessive torque. In essence, they are used to shut down a machine and dissipate any rotational energy without causing damage to the machine. Often, systems operating at low speeds can develop a large quantity of torque. In the event of a […]
What are bellows couplings? Technical summary for design engineers
Bellows couplings are one form of flexible coupling with twin coupling ends called hubs capping a precision-engineered corrugated tube that serves as the coupling body. Bellows couplings are known for their exceptional torsional rigidity to accurately transmit velocity, angular position, and torque. Their slight flexibility (at the corrugated bellows) serves to address limited amounts of […]
What are roller chains? Technical Summary for Motion Engineers
Updated April 2015. || In any motion control system, the object is ultimately to move some kind of load. The component in the motion system that converts electrical energy into mechanical energy is the motor. But the task doesn’t end there. A motor’s output shaft has to connect somehow to whatever the load is. This […]
