Immediate coupling between servo engine and worm gear is among the essential strengths of EP worm gearmotors, which combine DC engine technology with exceptional strength and wear resistance. Engine and gearbox were created as one single, compact unit. Because of their reduced current pull, these gearmotors deliver more accurate control of working temperature and higher efficiency.

We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or without integrated linear lead screw / ball screw adapted to your flexible modular concept.
Based on this we are able to select a wide variety of regular customizations to meet up 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 with regards to power, high efficiency, quiet and vibration-free operation, long life, high level of resistance to vibration, pressure or temperature, integrated linear screw, or a mixture of such properties, our item range with an increase of than 1000 different standard gearboxes is probably a good begin to be able to deliver a product that stands out in your favor.
Compact gearboxes are high-quality gearboxes for regular drives. The electric electric motor is included with the gearbox right into a single device (the first equipment is directly on the motor shaft). Separate 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 specialists will be happy to help you make your selection. We will be happy to send you documentation or design the right set directly, on demand.

Ever-Power worm gearboxes possess earned a reputation to be a business 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 wide choice of mounting choices, shaft configurations and motor interfaces, makes the Ever-Power worm gearbox the default choice for the industry. The helical-worm and the double-worm version, with or without the torque limiter, add up to the advantage, creating an extremely versatile drive system.
Ever-Power Worm gearboxes provide high torque with low velocity gear ratio. Being basic and compact in style, these gears can achieve higher gear ratio compared to the helical gears. These worm reduction gears having screw type qualities act like helical gears, but its helix angle is typically comparatively bigger) and its body is normally quite lengthy in the axial path. The gears in these gearboxes can be correct or left-handed dependant on the purpose.
Mounting choice include universal housing, aspect flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (solitary or double), with torque arm or torque limiter.
Top Quality Geared Motors. Ever-Power gearboxes and geared motors will be the electro-mechanical key elements for low backlash, smoothly 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 installation positions and applications, making them much popular 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 simply by FEM (Finite Element Method). This tooth geometry guarantees optimum rolling contact under load.
The special tooth root style in mixture with tooth helix angle, tooth depth, the materials used and surface finish maximizes load capacity. This high gearing capacity allows smaller wheels to be used for the same torque, and smaller sized gears with extraordinary power density can also increase reliability. Ever-Power geared motors are as a result incredible space savers.
Gearing produced with such micro-geometric precision allows the gearing enjoy required for troublefree rolling get in touch with to be substantially reduced and then the gear backlash to become minimized.
Dual chamber shaft seals developed by Ever-Power are utilized as regular in parallel shaft, shaft installed and helical worm gears for a higher 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
