New energy-efficient gear units are compact and low-cost
02 June 2013
SEW Eurodrive has launched two compact, energy-efficient, helical-bevel gear units for low power applications, up to 130Nm, providing an efficiency of over 90 percent.
The new K19 and K29 units deliver considerable energy savings and allow the use of smaller motors, therefore enabling the reduction of the size and weight of the overall drive.
The new gear units can be combined with SEW Eurodrive's entire range of motors, including the DR series of standard asynchronous motors, as well as the LSPM motor (IE4), and the CMP series of synchronous servomotors. The DRC electronic motor (IE4) is a particularly good match for an energy-efficient combination.
The low-loss K19 and K29 gear units have hypoid gearing in the output stage. This is available in three different gear ratios that make it possible for the gear units to reach overall ratios from 3 to 70. The gearing is designed with infinite fatigue strength that results in a nearly wear-free drive.
With a two-part aluminium universal housing the new units are equally suited to either foot or shaft mounting. Three standard base strips allow the drive to be optimally mounted on the driven machine, even when there is very little space available. This reduces the number of variants and the amount of stock required – advantages that are important to more than just designers of standard machines.
Typical applications include lifts for small loads, materials handling, transportation and logistics, as well as a whole range of tasks in sectors such as food and drink, and the automotive industry.
