Spiral bevel gearboxes
Ever-Power spiral bevel gearboxes are suitable for universal use thanks to their machine-friendly structure and adaptability. The efficient and reliable top performer is obtainable in different versions. Like all Ever-Power spiral bevel gearboxes, they are manufactured using the modern production approach to ground circular arc teeth according to Ever-Power. For clients, this means better toothing quality and precision and also even faster delivery times.

Ever-Power wide variety of spiral bevel gearboxes are characterised by high quality and robust performance by virtue of the gear housing manufactured from cast iron. Our spiral bevel gearboxes are produced in four different versions. The drive and the wheel are primarily made with Ever-Power spiral gearing offering a quiet, 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 transmission of high torques in low revolutions. The bearings are solid conical roller bearings on polished bearing seats.
Type “L” is a particular gearbox manufactured according to client requirements.
Our spiral bevel gearboxes could be given up to 4 shafts, hollow shaft and with an output torque as high as 1,000 Nm and can end up being fitted with a motor flange with a coupling for direct installation 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 can also be supplied as reversing gears. All spiral bevel gearboxes are life-time lubricated and will be provided in a hygienic edition with a lubricant authorized for the meals industry, with stainless steel shafts and with a rustproof yellow chromated gear housing. If there is a need for special shafts or flanges, we’ve great experience in adapting gearboxes – actually in smaller amounts – or in designing particular gearboxes for instance with gear housings in stainless 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 in bevel gears from the variations 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 have helix angles. However, due to the actual fact that manufacture facilities for straight bevel gears have become rare and the fact that straight bevel gears teeth can’t be polished, making spiral bevel gears which may be polished superior in terms of noise reduction, spiral bevel gears will probably become more common later on.
Bevel gears could be generally categorized by their manufacturing strategies, namely the Gleason technique and Klingelnberg method, which each possess 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 tested their versatility and value time by being extremely precise with suprisingly low backlash and incredibly low transmission error. Silent, shock resistant, have overload capability and are space saving.
The high precision spiral bevel gearbox can be used worldwide in paper processing, food processing, automotive and specialty engineering. An “understanding” when it comes 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 thoroughly spaced to allow lubricants to become spread evenly. The spiral bevel gears in a Ever-Power gearbox are exactly adjusted via a unique, adjustable locknut style.
Spiral bevel gears are made for applications that want high swiftness 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 risk of overheating. Curved tooth and deeper traction between those tooth ensures greater asset availability to boost flexible performance and prolong equipment life.
Spiral bevel gears are bevel gears with helical teeth positioned in a 90-level angle. The teeth are designed with a slight curve to supply better versatility and traction. Although they can be considered a hypoid gear, they have no offsets, which indicates they will not slip during procedure. This ensures smooth, dependable transmission perfect for high-speed, high-torque applications.
