Direct coupling between servo electric motor and worm gear is among the essential strengths of EP worm gearmotors, which combine DC electric motor technology with exceptional durability and wear resistance. Electric motor and gearbox are designed as one single, compact unit. Because of their reduced current pull, these gearmotors deliver more accurate control of operating temperature and higher performance.

We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or without integrated linear lead screw / ball screw adapted to our flexible modular concept.
Based upon this we are able to select a wide selection of standard customizations to meet up the requirements of various properties that are essential for each application.
If your application takes a gearbox with some special home such as for example small dimensions or low weight with regards to power, high efficiency, quiet and vibration-free operation, extended life, high resistance to vibration, pressure or temperature, integrated linear screw, or a mixture of this kind of properties, our item range with more than 1000 different standard gearboxes is probably a good start to have the ability to deliver a product that stands out in your favor.
Compact gearboxes are high-quality gearboxes for regular drives. The electric electric motor is included with the gearbox into a single unit (the first equipment is on the electric motor shaft). Separate gearboxes for link with conventional IEC motors may also be supplied on request.
Due to the complexity of the gearboxes’ configuration, they can not be purchased inside our e-shop. Our professionals will be pleased to help you make your selection. We will be happy to send you documentation or design the right set directly, on demand.

Ever-Power worm gearboxes possess earned a popularity to be an industry benchmark worldwide. Our success came from our relentless drive for quality with state-of-the-art technology, all while offering worm gearboxes are inexpensive prices. High versatility accorded through a wide choice of mounting choices, shaft configurations and motor interfaces, makes the Ever-Power worm gearbox the default choice for the market. The helical-worm and the double-worm edition, with or without the torque limiter, add up to the advantage, creating a highly versatile drive system.
Ever-Power Worm gearboxes provide high torque with low acceleration gear ratio. Being basic and compact in design, these gears can perform higher gear ratio compared to the helical gears. These worm reduction gears having screw type characteristics act like helical gears, but its helix angle is typically comparatively bigger) and its body is generally quite lengthy in the axial direction. The gears in these gearboxes could be right or left-handed depending upon the purpose.
Mounting option include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (single or dual), with torque arm or torque limiter.
EXCELLENT Geared Motors. Ever-Power gearboxes and geared motors are the electro-mechanical key components for low backlash, easily running and highly dynamic drive systems.
Our high-performance gear products are built to withstand the toughest commercial applications.
The gear housings are machined on all sides and invite diverse installation positions and applications, producing them much sought after in the industry. Consequently our geared motors tend to be to be found within our customers own devices.
The smooth running of Ever-Power gear units and the outstanding load capacity of WATT teeth are achieved with 3D design supported by FEM (Finite Element Method). This tooth geometry guarantees optimum rolling contact under load.
The special tooth root style in mixture with tooth helix angle, tooth depth, the materials used and surface finish maximizes load capacity. This high gearing capacity enables smaller tires to be used for the same torque, and smaller gears with outstanding power density also increase reliability. Ever-Power geared motors are as a result incredible space savers.
Gearing manufactured with such micro-geometric accuracy allows the gearing play necessary for troublefree rolling get in touch with to be substantially reduced and therefore the gear backlash to end up being minimized.
Double chamber shaft seals developed by Ever-Power are utilized as regular in parallel shaft, shaft mounted and helical worm gears for a higher level of tightness.
Ever-Power’s modular equipment technology meets certain requirements of advanced drive systems:
Excellent power density
Diverse mounting options
Precision Worm Gearboxes & Geared Motors
EP’s precision worm gearboxes are created for those more demanding applications where small size, high torque, high ratio, low backlash, low noise and long life time are required. Offered in 9 sizes, these worm gearboxes could be supplied with free input shaft, with hollow bore insight shaft and motor flange, and double decrease combination units for slow rate applications. Using cast iron housings, high quality bronze alloy worm tires and long life bearings, reliability and functionality are the key top features of this range.
