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 selection 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 property or home 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 a product that stands out on your side.
Small gearboxes are high-top quality gearboxes for standard drives. The electric electric motor is integrated with the gearbox into a single device (the first gear is on the engine 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 in 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 quality with state-of-the-art technology, all while offering worm gearboxes are affordable prices. High versatility accorded through a wide choice of mounting options, shaft configurations and motor interfaces, makes 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 high torque with low speed gear ratio. Being basic and compact in design, these gears can perform higher gear ratio compared to 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 body is normally quite long in the axial path. The gears in these gearboxes can 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 dynamic drive systems.
Our high-performance gear systems are built to withstand the toughest industrial 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 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 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 manufactured with such micro-geometric precision allows the gearing perform required for troublefree rolling get in touch with to be substantially reduced and therefore the gear backlash to be minimized.
Double chamber shaft seals developed by Ever-Power are used as standard for parallel shaft, shaft installed and helical worm gears for a high level of tightness.
Ever-Power’s modular gear technology meets the requirements of advanced drive systems:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
Precision Worm Gearboxes & Geared Motors
EP’s precision worm gearboxes are created for those more demanding applications where compact size, high torque, high ratio, low backlash, low sounds and long life time are required. Offered in 9 sizes, these worm gearboxes could be supplied with totally free input shaft, with hollow bore insight shaft and engine flange, and double decrease combination units for slow rate applications. Applying cast iron housings, high quality bronze alloy worm wheels and long life bearings, reliability and overall performance are the essential features of this range.
High Precision Right Position Transmission
Long Lifetime
WIDE RANGE Of Ratios
Special Surface Treatments
