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. ...

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. ...

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. ...

The fish sector encompasses all activities from catching, processing, transforming, and selling fish and seafood to meet all consumer needs. All these stages are important and each one plays a key role, therefore the environments where some of them take place are generally humid and susceptible to corrosion and contamination. REIMAN provides stainless steel electric motors designed for the food and beverage, cosmetics and pharmaceutical industries, among others. Industries that demand a high level of hygiene, safety and frequent washing, just like the fish industry. ...

Electric motors are indispensable in the industry and in our everyday life. Since its discovery that electric motors have evolved to this day, reducing in energy consumption with previous systems. Nowadays, energetic efficiency is a fundamental asset in all industries, due to the goal in reducing energy consumption and carbon footprint, as well as reducing operational costs. IE4 efficiency motors constitute a new generation prepared for this effect. ...

Unimec is marking a significant step in the ongoing pursuit of innovation and sustainability and this step is shared by our partnership. Unimec recently supplied four special-made screw jacks to a Norwegian shipping company with a strong reputation for its commitment to eco-friendly shipping. The project where these screw jacks will be used is one of the world’s first 100% electric ferryboat prototypes. A fact that makes Unimec, as a partner in ecological innovation, also important in the mobile sustainability transition. ...

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. ...

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. ...

Electric motors have a very high energy cost due to the amount of energy they require to convert electrical energy into mechanical energy. Today, these devices are responsible for more than half of the world's industrial energy consumption. ...
