The Worm And Wheel Apparatus ProDynami - 1224 studies worm and wheel mechanism performance, converting circular motion to linear motion or vice versa. This Worm And Wheel Apparatus features a bronze worm gear wheel, steel worm, and ball bearing-mounted pulleys for applying load and effort forces. It offers dual transmission ratios of 30:1 and 36:1 for efficiency and friction studies. Separate weight sets and a comprehensive instruction manual are included.

Construction and Design
The Worm And Wheel Apparatus ProDynami - 1224 consists of a worm and wheel mechanism, with the worm gear wheel made of bronze and the worm made of steel. Two aluminium side drums are fitted, with diameters of 100mm and 120mm on the worm shaft and 120mm on the worm gear wheel shaft. The worm drive has an axle base of Φ80mm, a transmission ratio of 30:1 and 36:1, and a modulus of 3 to 4mm. The worm, worm gear wheel, and pulleys are ball bearing-mounted on an HDF base plate. Pulleys connect the worm and wheel mechanism to apply load and effort forces, using cord and hangers. Weights are applied on the worm shaft (1x 0.5N hanger, 2x 0.5N, 2x 1N, 2x 2N, 2x 5N) and on the worm wheel (1x 1N hanger, 1x 10N, 3x 20N).
Scope of Delivery
Q: What is the Worm And Wheel Apparatus ProDynami - 1224 used for?
A: It is used to study the performance of a worm and wheel mechanism, including transmission ratio, torque, friction, self-locking, and efficiency.
Q: What materials are the worm and worm gear wheel made of?
A: The worm gear wheel is made of bronze, and the worm is made of steel.
Q: What transmission ratios does the apparatus offer?
A: The apparatus offers transmission ratios of 30:1 and 36:1.
Q: How are load and effort forces applied?
A: Load and effort forces are applied using pulleys connected to the worm and wheel mechanism, with cord and hangers.
Q: What weight sets are included with the apparatus?
A: Separate weight sets are included for the worm shaft (1x 0.5N hanger, 2x 0.5N, 2x 1N, 2x 2N, 2x 5N) and the worm wheel (1x 1N hanger, 1x 10N, 3x 20N).
