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

We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or perhaps without integrated linear lead screw / ball screw adapted to our flexible modular concept.
Based with this we can select a wide selection of regular customizations to meet the requirements of varied properties that are essential for each application.
If your application requires a gearbox with some special home such as small dimensions or low weight in relation to electricity, high efficiency, quiet and vibration-free operation, extended life, high resistance to vibration, pressure or temperature, integrated linear screw, or a combination of such properties, our product range with more than 1000 different standard gearboxes is most likely an excellent start to be able to deliver something that stands out on your side.
Small gearboxes are high-quality gearboxes for standard drives. The electric motor is integrated with the gearbox right into a single device (the first equipment is directly on the motor shaft). Separate 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 in our e-shop. Our specialists will be happy to help you create your selection. We are happy to send out you documentation or style a suitable set directly, on ask for.

Ever-Power worm gearboxes have earned a status to be an industry benchmark worldwide. Our success came from our relentless travel for quality with state-of-the-artwork technology, all while offering worm gearboxes will be affordable prices. High versatility accorded through a broad choice of mounting choices, shaft configurations and motor interfaces, would make the Ever-Electricity worm gearbox the default personal preference for the sector. The helical-worm and the double-worm version, with or without the torque limiter, add up to the advantage, creating an extremely versatile drive system.
Ever-Ability Worm gearboxes provide substantial torque with low 
rate gear ratio. Being basic and compact in design, these gears can perform higher gear ratio than the helical gears. These worm reduction gears having screw type qualities are similar to helical gears, but its helix angle is typically comparatively larger) and its body is normally quite lengthy in the axial direction. The gears in these gearboxes can be proper or left-handed depending upon the purpose.
Mounting option include universal housing, side 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-Electric power gearboxes and geared motors are the electro-mechanical key components for low backlash, efficiently running and highly dynamic drive systems.
Our high-performance gear devices are designed to withstand the toughest industrial applications.
The gear housings are machined on all sides and permit diverse mounting positions and applications, producing them much popular in the industry. As a result 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 ensures optimum rolling contact under load.
The special tooth root design in combination with tooth helix angle, tooth depth, the components used and surface finish maximizes load capacity. This excessive gearing capacity allows smaller tires to be utilized for the comparable torque, and smaller sized gears with exceptional power density also increase reliability. Ever-Electric power geared motors are therefore incredible space savers.
Gearing produced with such micro-geometric precision allows the gearing perform required for troublefree rolling get in touch with to be substantially reduced and therefore the equipment backlash to end up being minimized.
Double chamber shaft seals developed by Ever-Power are used as standard for parallel shaft, shaft installed and helical worm gears for a higher level of tightness.
Ever-Power’s modular equipment technology meets certain requirements of advanced drive devices:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
Precision Worm Gearboxes & Geared Motors
