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

We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or without integrated linear business lead screw / ball screw adapted to our flexible modular concept.
Based upon this we are able to select a wide selection of standard customizations to meet up the requirements of varied properties that are essential for each application.
If your application takes a gearbox with some special house such as small dimensions or low weight in relation to power, high efficiency, quiet and vibration-free operation, long life, high resistance to vibration, pressure or temperature, integrated linear screw, or a mixture of such properties, our product range with an increase of than 1000 different standard gearboxes is probably a good start to be able to deliver a product that stands out in your favor.
Compact gearboxes are high-quality gearboxes for regular drives. The electric motor is included with the gearbox right into a single unit (the first gear is on the motor shaft). Separate gearboxes for link with conventional IEC motors may also be supplied on request.
Due to the complexity of the gearboxes’ configuration, they cannot be purchased inside our e-shop. Our experts will be pleased to help you create your selection. We are happy to send you documentation or style a suitable set directly, on demand.

Ever-Power worm gearboxes have earned a status to be an industry benchmark worldwide. Our achievement came from our relentless drive for quality with state-of-the-artwork technology, all while offering worm gearboxes are inexpensive prices. High versatility accorded through a broad choice of mounting choices, shaft configurations and 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, soon add up to the advantage, creating an extremely versatile drive system.
Ever-Power Worm gearboxes provide high torque with low rate gear ratio. Being simple and compact in style, these gears can perform higher gear ratio compared to 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 body is normally quite long in the axial path. The gears in these gearboxes can be right or left-handed dependant on the purpose.
Mounting choice include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (solitary or double), with torque arm or torque limiter.
EXCELLENT Geared Motors. Ever-Power gearboxes and geared motors are the electro-mechanical key components for low backlash, efficiently running and highly powerful drive systems.
Our high-performance gear systems are designed to withstand the toughest industrial applications.
The apparatus housings are machined on all sides and invite diverse mounting positions and applications, producing them much popular in the industry. Consequently 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 design in mixture with tooth helix angle, tooth depth, the materials used and surface finish maximizes load capacity. This high gearing capacity allows smaller tires to be utilized for the same torque, and smaller sized gears with outstanding 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 contact to be substantially reduced and then the gear backlash to become minimized.
Double chamber shaft seals developed by Ever-Power are used as regular in 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 systems:
Excellent power density
Diverse mounting options
Precision Worm Gearboxes & Geared Motors
