Spiral bevel gearboxes
Ever-Power spiral bevel gearboxes are ideal for universal use thanks to their machine-friendly construction and adaptability. The efficient and reliable top performer is obtainable in different variations. 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 faster delivery times.

Ever-Power wide range of spiral bevel gearboxes are characterised by high quality and robust functionality by virtue of the gear housing made of cast iron. Our spiral bevel gearboxes are manufactured in four different variations. The drive and the wheel are mainly made out of Ever-Power spiral gearing offering a silent, steady and efficient operation.
Type EP may be the standard version where the bedding includes strong single-row deep groove ball bearings on polished bearing seats.
Type “Electronic” and “P” are gearboxes designed for tranny of high torques in low revolutions. The bearings are strong conical roller bearings on polished bearing seats.
Type “L” is a special gearbox manufactured according to client 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 will be fitted with a engine flange with a coupling for direct mounting of the motor.
The spiral bevel gearboxes can be found in the following gear ratios 1:1, 1,5:1, 2:1 and 3:1 and may also be supplied as reversing gears. All spiral bevel gearboxes are life-period lubricated and may be supplied in a hygienic version with a lubricant accepted for the meals industry, with stainless shafts and with a rustproof yellow chromated gear housing. If there is a need for special shafts or flanges, we have great experience in adapting gearboxes – also in smaller numbers – or in designing special gearboxes for instance with gear housings in stainless steel or as precision gearboxes with reduced backlash.
The standard definition of a Bevel Gear is a cone-shaped gear which transmits power between 2 intersecting axels.
Looking at bevel gears from the differences in helix angles, they could be generally classified into straight bevel gears, which don’t have helix angles, and spiral bevel gears (which includes zerol bevel gears), which do have helix angles. However, because of the fact that manufacture facilities for straight bevel gears are becoming rare and the actual fact that straight bevel gears teeth cannot be polished, making spiral bevel gears which can be polished superior when it comes to noise decrease, spiral bevel gears will probably become more common in the future.
Bevel gears could be generally classified by their manufacturing strategies, namely the Gleason method and Klingelnberg method, which each have differing teeth shapes, and presently most gears use the Gleason method. Incidentally, all gears manufactured by Ever-Power utilize the Gleason method.

The spiral bevel gearboxes for torques up to 8,000 Nm have confirmed their versatility and value time when you are extremely precise with very low backlash and very low transmission error. Silent, shock resistant, possess overload capability and so are space saving.
The high precision spiral bevel gearbox is utilized 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 cautiously spaced to permit lubricants to end up being spread evenly. The spiral bevel gears in a Ever-Power gearbox are exactly adjusted with a unique, adjustable locknut design.
Spiral bevel gears are designed for applications that want high speed and high torque power. They can help cut customer costs by providing long-lasting performance with reduced need for repairs or replacements. With spiral bevel gears, there is no need for offsets and a considerably reduced threat of overheating. Curved tooth and deeper traction between those tooth 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-degree angle. The teeth are designed with a slight curve to provide better flexibility 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 well suited for high-speed, high-torque applications.
