Immediate coupling between servo electric motor and worm gear is among the important strengths of EP worm gearmotors, which incorporate DC electric motor technology with exceptional toughness and wear resistance. Electric motor and gearbox are designed as one single, compact unit. Because of their reduced current pull, these gearmotors deliver additional accurate control of working temperature and higher performance.

We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or maybe without integrated linear business lead screw / ball screw adapted to your flexible modular concept.
Based with this we are able to select a wide variety of common customizations to meet up the requirements of various properties that are important 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 electricity, high efficiency, quiet and vibration-free operation, long 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 most likely an excellent start to have the ability to deliver something that stands out on your side.
Small gearboxes are high-quality gearboxes for standard drives. The electric electric motor is included with the gearbox into a single device (the first gear is on the motor shaft). Individual gearboxes for connection to conventional IEC motors may also be supplied on request.
Because of the complexity of the gearboxes’ configuration, they can not be purchased inside our e-shop. Our experts will be happy to help you create your selection. We will be happy to send you documentation or design the right set directly, on demand.

Ever-Power worm gearboxes have earned a popularity to be a business benchmark worldwide. Our success came from our relentless get for level of quality with state-of-the-art technology, all while offering worm gearboxes are affordable prices. High versatility accorded through a broad choice of mounting choices, shaft configurations and electric motor interfaces, produces 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, soon add up to the advantage, creating an extremely versatile drive system.
Ever-Vitality Worm gearboxes provide great torque with low swiftness 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 characteristics act like helical gears, but its helix angle is typically comparatively bigger) and its own body is generally quite long in the axial path. The gears in these gearboxes could be suitable or left-handed dependant on the purpose.
Mounting option include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (single or double), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Electricity gearboxes and geared motors will be the electro-mechanical key elements for low backlash, easily running and highly powerful drive systems.
Our high-performance gear products are built 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. Consequently our geared motors tend to be to be found within 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 supported simply by FEM (Finite Element Method). This tooth geometry guarantees optimum rolling get in touch with under load.
The special tooth root design in mixture with tooth helix angle, tooth depth, the materials used and surface finish maximizes load capacity. This large gearing capacity allows smaller tires to be utilized for the same torque, and smaller gears with exceptional power density also increase reliability. Ever-Electrical power geared motors are therefore incredible space savers.
Gearing produced with such micro-geometric accuracy allows the gearing perform necessary for troublefree rolling get in touch with to be substantially reduced and therefore the gear backlash to be minimized.
Dual chamber shaft seals developed by Ever-Power are used as standard for parallel shaft, shaft mounted and helical worm gears for a high level of tightness.
Ever-Power’s modular equipment technology meets the requirements of advanced drive systems:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
