Parvalux Electric Motors has introduced the LS Gearbox, a compact range of worm wheel gearboxes rated up to 35Nm continuous output torque. Similar to the recently launched G Gearbox range, the smaller LS features the same advanced design and technological developments that have established new standards for performance and reliability across the range. As a measure of Parvalux’s confidence in the durability, reliability and performance of its LS gearboxes, each unit carries a five-year warranty.
The LS range features a direct drive between the gearbox and motor which, unlike many similar products, does not employ any rubber or moulded components that could wear or degrade with time and use. The result is a gearbox unit that offers exceptional performance and class leading durability.
The rugged gearbox is based on 100mm square, cast aluminium design that features industry standard 3, 4 or 5 point mountings. The ‘sealed for life’ construction uses a high performance lubricant and the gearboxes are suitable for running in any position. Available ratios include 12.5, 25, 30, 50, 75 and 100:1.
Gears are designed for minimum noise and there is a choice of Delrin, which gives a maximum torque of up to 20Nm, or high torque bronze gears for more demanding applications up to 35Nm. Output speeds range from 25 to 600 rpm and, in common with all Parvalux gearboxes, there is a huge range of options that enables the gearbox to be customised to meet the exact requirements of individual applications. These options can include for example, solid or hollow output shafts up to 25mm in diameter and mechanical brakes. LS gearboxes can be supplied as individual units or in production quantities.
The new LS range is produced in the UK and can be integrated with Parvalux’s compact and efficient range of high performance ac induction, permanent magnet dc or dc brushless motors. dc Brushless motors can also be supplied with an integrated speed controller, to provide a complete motor gearbox solution.
