What are Screw Jacks?
Screw Jacks are devices whose function is to convert circular motion into linear motion. This is a mechanism that can be used to move weights with a minimal applied force, by means of a spindle driving the carried weight. Screw jacks' different application approaches envolve carrying weight by pushing or pulling, lifting or lowering, locking or unlocking, sliding, rolling, tilting and tensioning. Whatever type of screw jack is added, the carrying capacities can be used in applications for small weights from just a few kilograms up to hundreds of tons. ...

Rack/Pinion Set: Straight or Helical Teeth?
A rack is essentially a toothed bar that pairs with a gear wheel. Together, they convert rotational into linear movement, or vice versa. These features make the rack/pinion assembly essential in transmission systems.
There are two types of rack/pinion sets, straight-toothed and helical-toothed. ...

How do Variable Frequency Drives improve the performance of HVAC-R air conditioning systems?
The concept of air conditioning involves control over the environmental conditions of an enclosed space. This includes temperature, humidity, air quality and air speed.
The entire process of air conditioning, which involves altering and treating the air, incorporates systems such as heating, ventilation, air conditioning and refrigeration, known by the acronym HVAC-R.
All HVAC-R systems originally operate with fixed-speed motors. Variable frequency drives come to customize each system to obtain the best result. ...

What is the irreversibility of a gearbox
Sometimes there are particular applications wich require complete reversibility, sometimes complete irreversibility of the worm and wheel gearbox.
Therefore, this is why it is important to explain the behaviour of a worm and wheel gearbox when the rotation speed of the worm s reduced on the worm wheel. ...

What are couplings and what do they do?
A coupling is a mechanical component that connects 2 shafts which are intended to rotate in order to transmit power. Shaft couplings introduce some flexibility into mechanical transmission by providing tolerance to shaft misalignment. As a result, this coupling flexibility can reduce uneven bearing wear, equipment vibration and other mechanical problems due to misalignment. ...
