Worm And Wheel Apparatus | ProDynami – 1224
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.
The Worm And Wheel Apparatus ProDynami – 1224 studies the performance of a worm and wheel mechanism, containing a circular gear and a toothed rod. This Worm And Wheel Apparatus converts or transmits circular motion to linear motion or vice versa. It uses pulleys, cord, and hangers to apply load and effort forces.
Product Overview
This unit is designed to study the performance of a worm and wheel mechanism. It is a mechanism that contains a circular gear and a rod on which teeth are made. This mechanism is used to convert or transmit circular motion to linear motion or vice versa. The unit consists of a worm and wheel mechanism. Both are connected with pulleys to apply load and effort forces. To apply forces, cord and hanger are used on this Worm And Wheel Apparatus.

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
- 1 experimental unit
- 1 instruction manual
- 1 thread
- 2 sets of weight
