We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or maybe without integrated linear lead screw / ball screw adapted to your flexible modular concept.
Based about this we can select a wide variety of normal customizations to meet the requirements of various properties that are important for each application.
If your application takes a gearbox with some special home such as small dimensions or low weight in relation to ability, high efficiency, quiet and vibration-free operation, long life, high level of resistance to vibration, pressure or temperature, integrated linear screw, or a combination of this kind of properties, our product range with more than 1000 different standard gearboxes is probably an excellent start to be able to deliver a product that stands out in your favor.
Small gearboxes are high-top quality gearboxes for regular drives. The electric engine is included with the gearbox right into a single device (the first gear is directly on the engine shaft). Individual gearboxes for link with conventional IEC motors can also be supplied on request.
Due to the complexity of the gearboxes’ configuration, they cannot be purchased inside our e-shop. Our experts will be happy to help you create your selection. We will be happy to send out you documentation or design the right set directly, on ask for.

Ever-Power worm gearboxes have earned a reputation to be an industry benchmark worldwide. Our achievement came from our relentless drive for top quality with state-of-the-artwork technology, all and will be offering worm gearboxes will be affordable prices. High versatility accorded through a wide choice of mounting options, shaft configurations and electric motor interfaces, would make the Ever-Electric power worm gearbox the default determination for the market. The helical-worm and the double-worm edition, with or without the torque limiter, soon add up to the advantage, creating an extremely versatile drive system.
Ever-Electric power Worm gearboxes provide excessive torque with low rate gear ratio. Being simple and compact in style, these gears can achieve higher gear ratio than the helical gears. These worm decrease gears having screw type qualities act like helical gears, but its helix angle is typically comparatively larger) and its own body is normally quite lengthy in the axial path. The gears in these gearboxes could be ideal or left-handed depending upon the purpose.
Mounting choice include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (one or double), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Ability gearboxes and geared motors are the electro-mechanical key components for low backlash, smoothly running and highly powerful drive systems.
Our high-performance gear devices are built to withstand the toughest industrial applications.
The apparatus housings are machined on all sides and permit diverse mounting positions and applications, making them much sought after in the industry. Because of this 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 backed by FEM (Finite Element Method). This tooth geometry ensures optimum rolling get in touch with under load.
The special tooth root design in mixture with tooth helix angle, tooth depth, the components used and surface finish maximizes load capacity. This great gearing capacity allows smaller tires to be utilized for the exact torque, and smaller sized gears with excellent power density also increase reliability. Ever-Ability geared motors are therefore incredible space savers.
Gearing manufactured with such micro-geometric accuracy allows the gearing enjoy required for troublefree rolling contact to be substantially decreased and therefore the equipment backlash to become minimized.
Double chamber shaft seals produced by Ever-Power are used as standard on parallel shaft, shaft installed and helical worm gears for a high level of tightness.
Ever-Power’s modular equipment technology meets the requirements of advanced drive programs:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
