Oldham Coupling | ProDynami - 1342
Product Overview
The Oldham Coupling ProDynami - 1342 connects two shafts using three discs joined by perpendicular tongue and groove arrangements. This Oldham Coupling maintains constant velocity between input and output shafts while permitting misalignment or end movement. It offers a compact design compared to two universal joints, suited for low speed shafts with parallel axes. The apparatus supports experiments on velocity ratio and central disc displacement.

Key Features
Key Features
- Disc Configuration: three discs, input, output, and middle, joined by tongue and groove
- Tongue and Groove Orientation: perpendicular arrangement between the two sides
- Constant Velocity: middle disc rotates at the same speed as input and output shafts
- Orbital Motion: middle disc center traces a circular orbit twice per rotation around the midpoint between shafts
- Compact Design: more compact than an equivalent arrangement using two universal joints
- Misalignment Tolerance: permits some degree of misalignment or end movement
- Application Range: suited for low speed shafts with parallel axes, demonstrated on this Oldham Coupling
Experiments
- To determine the velocity ratio across the coupling with various displacements and also to plot central disc displacement against rotational position
Construction and Design
The Oldham Coupling ProDynami - 1342 consists of three discs: one coupled to the input shaft, one coupled to the output shaft, and a middle disc joined to the first two by tongue and groove. The tongue and groove on one side of the middle disc is perpendicular to the tongue and groove on the other side. The middle disc rotates around its center at the same speed as the input and output shafts, with its center tracing a circular orbit twice per rotation around the midpoint between the input and output shafts. This design gives the coupling a more compact size compared to an equivalent arrangement using two universal joints.

Frequently Asked Questions
Q: What is the Oldham Coupling ProDynami - 1342 used for?
A: It is used to connect two shafts together for transmitting power while permitting some degree of misalignment or end movement, and to study velocity ratio and central disc displacement.
Q: How many discs does an Oldham coupling have?
A: An Oldham coupling has three discs: one coupled to the input, one coupled to the output, and a middle disc joined to the first two by tongue and groove.
Q: How does the middle disc move during operation?
A: The middle disc rotates around its center at the same speed as the input and output shafts, with its center tracing a circular orbit twice per rotation around the midpoint between the shafts.
Q: What advantage does an Oldham coupling have over two universal joints?
A: An Oldham coupling offers a more compact size compared to an equivalent arrangement using two universal joints.
Q: Where is an Oldham coupling typically used?
A: It is a constant velocity coupling used where low speed shafts are found with parallel axes.
