Spiral bevel gearboxes
Ever-Power spiral bevel gearboxes are suitable for universal use because of their machine-friendly construction and adaptability. The effective and reliable best performer is obtainable in different versions. Like all Ever-Power spiral bevel gearboxes, they are produced using the present day production approach to ground circular arc the teeth according to Ever-Power. For customers, this means greater toothing quality and precision as well as even more quickly delivery times.

Ever-Power wide variety of spiral bevel gearboxes are characterised by top quality and robust performance by virtue of the gear housing made of cast iron. Our spiral bevel gearboxes are produced in four different variations. The drive and the wheel are generally made out of Ever-Power spiral gearing providing a peaceful, steady and efficient operation.
Type EP is the standard version where in fact the bedding contains strong single-row deep groove ball bearings on polished bearing seats.
Type “Electronic” and “P” are gearboxes designed for transmission of high torques in low revolutions. The bearings are solid conical roller bearings on polished bearing chairs.
Type “L” is a special gearbox manufactured according to consumer requirements.
Our spiral bevel gearboxes can be supplied with up to 4 shafts, hollow shaft and with an output torque as high as 1,000 Nm and can become fitted with a motor flange with a coupling for direct installation of the motor.
The spiral bevel gearboxes can be found in the next gear ratios 1:1, 1,5:1, 2:1 and 3:1 and can also be supplied as reversing gears. All spiral bevel gearboxes are life-period lubricated and can be provided in a hygienic version with a lubricant approved for the food industry, with stainless steel shafts and with a rustproof yellowish chromated gear housing. When there is a need for special shafts or flanges, we have great experience in adapting gearboxes – also in smaller amounts – or in designing special gearboxes for example with equipment housings in stainless steel or as precision gearboxes with reduced backlash.
The typical definition of a Bevel Gear is a cone-shaped gear which transmits power between 2 intersecting axels.
Looking at bevel gears from the distinctions in helix angles, they may be generally classified into directly bevel gears, which don’t have helix angles, and spiral bevel gears (which includes zerol bevel gears), which do possess helix angles. However, due to the actual fact that manufacture facilities for directly bevel gears have become rare and the fact that directly bevel gears teeth can’t be polished, producing spiral bevel gears which can be polished superior in conditions of noise reduction, spiral bevel gears are likely to become more common later on.
Bevel gears could be generally classified by their manufacturing strategies, namely the Gleason technique and Klingelnberg method, which each have differing teeth forms, and presently most gears utilize the Gleason technique. Incidentally, all gears produced by Ever-Power use the Gleason method.

The spiral bevel gearboxes for torques up to 8,000 Nm have confirmed their versatility and value time by being extremely precise with very low backlash and very low transmission error. Silent, shock resistant, have overload capability and so are space saving.
The high precision spiral bevel gearbox can be used worldwide in paper processing, food processing, automotive and specialty engineering. An “understanding” with regards to quality, diversity, longevity and reliability.
The modified helical teeth of spiral bevel gears create reliable, tooth-to-tooth traction that minimizes backlash and prevents the gears from slipping. The gears are carefully spaced to permit lubricants to be spread evenly. The spiral bevel gears in a Ever-Power gearbox are precisely adjusted via a unique, adjustable locknut design.
Spiral bevel gears are created for applications that require high swiftness and high torque power. They can help cut consumer costs by providing long-lasting performance with minimal need for repairs or replacements. With spiral bevel gears, there is no need for offsets and a significantly reduced threat of overheating. Curved teeth and deeper traction between those teeth ensures better asset availability to boost flexible performance and extend equipment life.
Spiral bevel gears are bevel gears with helical teeth situated in a 90-level angle. The teeth are designed with hook curve to provide better versatility and traction. Although they could be considered a hypoid gear, they have no offsets, which indicates they will not slip during operation. This ensures smooth, reliable transmission perfect for high-speed, high-torque applications.
