Direct coupling between servo engine and worm gear is among the crucial strengths of EP worm gearmotors, which combine DC motor technology with exceptional strength and wear resistance. Engine and gearbox were created as one single, compact unit. Thanks to their reduced current draw, 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 lead screw / ball screw adapted to our flexible modular concept.
Based on this we are able to select a wide selection of standard customizations to meet the requirements of varied properties that are important for each application.
If your application requires a gearbox with some special home such as small dimensions or low weight with regards to power, high efficiency, quiet and vibration-free operation, long life, high resistance to vibration, pressure or temperature, integrated linear screw, or a combination of such properties, our item range with an increase of than 1000 different standard gearboxes is most likely a good start to have the ability to deliver something that stands out on your side.
Compact gearboxes are high-quality gearboxes for standard drives. The electric electric motor is built-in with the gearbox right into a single device (the first gear is on the electric 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 inside our e-shop. Our specialists will be pleased to help you create your selection. We will be happy to send you documentation or style a suitable set directly, on ask for.

Ever-Power worm gearboxes possess earned a status to be a business benchmark worldwide. Our success originated from our relentless drive for quality with state-of-the-art technology, all while offering worm gearboxes are affordable prices. High flexibility accorded through a wide choice of mounting options, shaft configurations and engine 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 rate gear ratio. Being basic and compact in design, these gears can perform higher gear ratio than the helical gears. These worm decrease gears having screw type qualities are similar to helical gears, but its helix position is typically comparatively bigger) and its own body is normally quite long in the axial direction. The gears in these gearboxes can be right or left-handed dependant on the purpose.
Mounting option include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (single or dual), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Power gearboxes and geared motors are the electro-mechanical key elements for low backlash, smoothly running and highly dynamic drive systems.
Our high-performance gear units are designed to withstand the toughest commercial applications.
The gear housings are machined on all sides and permit diverse mounting positions and applications, making them much sought after in the industry. As a result our geared motors tend to be to be found as part of our customers own machines.
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 guarantees optimum rolling get in touch with under load.
The special tooth root style 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 used for the same torque, and smaller gears with outstanding power density also increase reliability. Ever-Power geared motors are consequently incredible space savers.
Gearing manufactured with such micro-geometric precision allows the gearing enjoy required for troublefree rolling get in touch with to be substantially decreased and then the gear backlash to end up being minimized.
Double chamber shaft seals developed by Ever-Power are utilized as regular 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
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
