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

We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or without integrated linear business lead screw / ball screw adapted to your flexible modular concept.
Based on this we can select a wide variety of regular customizations to meet the requirements of various properties that are essential for each application.
If your application requires a gearbox with some special real estate such as for example small dimensions or low weight with regards to power, high efficiency, quiet and vibration-free operation, extended life, high level of resistance to vibration, pressure or temperature, integrated linear screw, or a combination of this kind of properties, our item range with an increase of than 1000 different standard gearboxes is most likely a good begin to be able to deliver something that stands out in your favor.
Compact gearboxes are high-quality gearboxes for regular drives. The electric electric motor is built-in with the gearbox into a single unit (the first gear is directly on the engine shaft). Separate gearboxes for link with conventional IEC motors can also be supplied on request.
Because of the complexity of the gearboxes’ configuration, they can not be purchased inside our e-shop. Our specialists will be happy to help you make your selection. We will be happy to send out you documentation or style the right set directly, on ask for.

Ever-Power worm gearboxes possess earned a reputation to be an industry benchmark worldwide. Our achievement originated from our relentless drive for quality with state-of-the-art technology, all while offering worm gearboxes are affordable prices. High versatility accorded through a wide choice of mounting choices, shaft configurations and electric 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 speed gear ratio. Being basic and compact in design, these gears can achieve higher gear ratio than the helical gears. These worm decrease gears having screw type characteristics act like helical gears, but its helix angle is typically comparatively bigger) and its own body is generally quite lengthy in the axial direction. The gears in these gearboxes can be correct or left-handed dependant on the purpose.
Mounting choice include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (one or dual), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Power gearboxes and geared motors will be the electro-mechanical key components for low backlash, smoothly running and highly powerful drive systems.
Our high-performance gear devices are designed to withstand the toughest commercial applications.
The apparatus housings are machined on all sides and invite diverse mounting positions and applications, making them much sought after in the industry. Because of this our geared motors are often to be found as part of 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 simply by FEM (Finite Element Method). This tooth geometry ensures optimum rolling get in touch with 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 high gearing capacity enables smaller tires to be utilized for the same torque, and smaller gears with excellent power density can also increase reliability. Ever-Power geared motors are therefore incredible space savers.
Gearing manufactured with such micro-geometric accuracy allows the gearing play required for troublefree rolling get in touch with to be substantially decreased and therefore the gear backlash to become minimized.
Double chamber shaft seals produced by Ever-Power are used as standard in parallel shaft, shaft installed and helical worm gears for a high level of tightness.
Ever-Power’s modular equipment technology meets certain requirements of advanced drive systems:
Excellent power density
Diverse mounting options
