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

We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or perhaps without integrated linear business lead screw / ball screw adapted to our flexible modular concept.
Based at this we can select a wide variety of normal customizations to meet the requirements of varied 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 in relation to electricity, high efficiency, quiet and vibration-free operation, long life, high level of resistance to vibration, tension or temperature, integrated linear screw, or a mixture of such properties, our product range with more than 1000 different standard gearboxes is probably an 
excellent start to have the ability to deliver something that stands out in your favor.
Compact gearboxes are high-quality gearboxes for standard drives. The electric engine is included with the gearbox right into a single unit (the first equipment is on the electric motor shaft). Separate gearboxes for connection to conventional IEC motors can also be supplied on request.
Due to the complexity of the gearboxes’ configuration, they can not be purchased inside our e-shop. Our experts will be pleased to help you make your selection. We will be pleased to send you documentation or design the right set directly, on ask for.

Ever-Power worm gearboxes possess earned a popularity to be an industry benchmark worldwide. Our achievement originated from our relentless travel for level of quality with state-of-the-art technology, all and will be offering worm gearboxes are affordable prices. High versatility accorded through a wide choice of mounting options, shaft configurations and motor interfaces, will make the Ever-Electrical power worm gearbox the default personal preference 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-Vitality Worm gearboxes provide large torque with low rate gear ratio. Being basic and compact in style, 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 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. Available in Solid shafts (solitary or dual), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Electrical power gearboxes and geared motors will be the electro-mechanical key elements for low backlash, efficiently running and highly dynamic drive systems.
Our high-performance gear products are built to withstand the toughest commercial applications.
The apparatus housings are machined on all sides and permit diverse mounting positions and applications, producing them much sought after in the industry. As a result 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 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 allows smaller wheels to be used for the equal torque, and smaller gears with outstanding power density also increase reliability. Ever-Electricity geared motors are as a result incredible space savers.
Gearing manufactured with such micro-geometric accuracy allows the gearing enjoy required for troublefree rolling get in touch with to be substantially reduced and therefore the gear backlash to become minimized.
Dual chamber shaft seals produced by Ever-Power are used as standard during parallel shaft, shaft mounted and helical worm gears for a higher level of tightness.
Ever-Power’s modular gear technology meets certain requirements of advanced drive programs:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
