Bevel Gear Units are used in many industries due to their compact design. In the following, we will explain their design and potential applications.
Gear Units and Geared Motors(a combination of a gear unit and a motor) are an essential part of any modern-day industry. They are used for many reasons, including:
Bevel gear units belong to a group of angled gear units, meaning that the input and output shaft are positioned at an angle to each other. This angle is usually 90° – if required, other angles can also be implemented. In its simplest form, a bevel gear unit consists of only one gear stage. However, NORD bevel gear units always have several gear stages: Our stage arrangement is as follows:
A gear stage is a wheel pairing within a gear unit that changes speed or torque. The torque changes proportionally to the speed changes from stage to stage. The factor is the same for both changes, but working in opposite directions. In case of a negative speed ratio, the output speed is reduced, while the torque is increased; a positive speed ratio causes the opposite effect. The shafts’ direction of rotation also changes in every stage. If this is not required, idler gears can be inserted.
A bevel gear stage consists of a bevel pinion and bevel gear (often a crown wheel). The stages can consist of straight, helical or spiral bevel gears (spiral or hypoid bevel gear). Speed ratios of 1:1 to 1:10 are usually achieved for each stage. This results in high efficiencies of 96 to 98% per stage. Please take note: Bevel gear units are not self-locking. If this feature is required, it must be implemented through other components, for example, a brake.
NORD's compact Bevel Geared Motors are the best choice wherever high speed ratios and torques are required. Our drive systems, consisting of an electric motor and a bevel gear unit, are especially suitable for use on conveyor belts as well as in intralogistics, packaging technology, and the food industry.
The Advantages of Our Bevel Geared Motors:
The UNICASE Bevel Geared Motor provides a torque range from 180 to 50,000 Nm and takes up little installation space thanks to the compact UNICASE housing. Like all other NORD bevel geared motors, the motor is available with an integrated back stop and integrated brake.
With our NORDBLOC.1® drive systems with bevel gear units, we have optimised performance even further: They are now our most powerful bevel geared motors. As standard, we manufacture the NORDBLOC.1® motors with bevel gear units with a high strength die cast aluminium housing.
We have developed our NORDBLOC.1® bevel geared motors from the series SK 930072.1 - SK 93772.1 especially for wash-down applications , for example in the food industry. This version has an especially smooth housing made of aluminium permanent mould castings, which is easy to clean and prevents the accumulation of dirt.
In combination with an IE4 synchronous motor, our 2-stage bevel gear units become the energy-efficient LogiDrive system for intralogistics. LogiDrive drive units have a large overload capacity and greatly reduce operating costs thanks to their high efficiency. Due to their modular structure, users also make considerable savings in maintenance costs.
The service-friendly and standardised modular system combines different NORD products into one drive solution, which is 100% tailored to the respective industry standards and application requirements. We differentiate between the sectors of post & parcel and airport on the one hand, and warehouse on the other. The first application area includes drives for parcel distribution and sorting systems as well as baggage handling, while the latter includes conventional warehouse applications such as pallet, container and overhead conveyors. In both areas, we offer a basic and advanced version.
For every area, there are advanced variants with IE5+ synchronous motor technology and a basic variant with IE3 asynchronous motors. While the LogiDrive advanced drives address issues such as energy efficiency, variant reduction and Total Cost of Ownership (TCO), the basic LogiDrive's main focus is on cost efficiency.
In detail, the product family comprises the following geared motor versions:
High load capacities, high torques and low noise: NORD’s MAXXDRIVE® right-angle gear units . With output torques of up to 260,000 Nm and powers of up to 4,000 kW, these gear units provide the necessary drive in heavy-duty applications such as conveyor belt systems, mixers, agitators, extruders, drums or mills. The right-angle gear units are available as 2-stage, 3-stage and 4-stage versions. Their gearwheels are made from high-quality steel alloys and are case-hardened. With our UNICASE housing, we can use larger roller bearings, which guarantee a long service life. Another advantage is that they can be easily installed on all six sides.
