Gears & Geared Motors

Geared motors
Optimal interaction
With classic drive mountings, the motor is connected to the gear using complicated intermediate couplings and adapter plates. This has the advantage that the motor is easy to exchange if ever it needs repairing.
However, if compact dimensions and low production costs are specified as the key requirements for a drive unit, an alternative solution has to be found. A radically simplified design is the only way to counter rising cost pressure. The adapter flange, couplings, pinion bearings and other connecting elements can all be eliminated by modifying the design accordingly. Where possible, a toothed motor shaft engages directly with the gear. The motor and gear flanges are joined together in a single part. An ultra-compact drive is the outcome.

Planetary gearsPlanetary gears
Planetary gears
High torques combined in a compact device
Planetary gears are mainly used when very high torques have to be transmitted while maintaining reduced external dimensions and low weight. Since the power is split between several planets, planetary gears can transmit much higher torques than spur or worm gears of the same size.
Lean motor-gear combinations are a particular advantage whenever only limited space is available, because high ratios and very good efficiency are possible simply by connecting the planetary stages in series. High gear ratios are easily achieved with just two or three stages.
Plastic gearwheels are often used in the input stage depending on the application, especially in drives which are sensitive to noise. The noise level can be further reduced by using helical teeth.

Spur gearsSpur gears
Spur gears
Hard-wearing and powerful
Spur gears are flexible all-rounders which can be used in umpteen different applications. They represent the best way to transmit rotary motions reliably at low ratios and high forces. The parallel arrangement of the input and output shafts results in a spatial separation which is often essential for design reasons.
In the case of multiple-stage spur gears, different directions of rotation as well as different torques and speeds can be converted at the various shafts. The shafts are mounted on bearings in the gear housing at both ends and may have to withstand very heavy loads owing to the large bearing distance. Ancillary equipment such as brakes or overload couplings can generally be adapted to the housing very easily. Spur gears can be designed with noise-optimised helical teeth or with robust straight teeth.

Thinking round corners
Worm gears are used when high ratios are called for in a single stage. The input and output shafts cross each other at an angle of 90° with this gear type. The constant tooth meshing between the worm and the worm wheel enables a significant reduction in the noise level. Worm gears can also be self-locking, though in this case they have lower efficiency.
With low ratios, bevel gears are a good alternative to worm gears. Bevel gears are not self-locking and have good efficiency. As with worm gears, the input and output are generally perpendicular to one another. To ensure optimal tooth meshing, the bevel gearsets must be fitted precisely.

Spur wheelsSpur wheels
Spur wheels
The rugged classic among gear designs
Spur wheel teeth usually form the basis for gears. Standardised involute toothing is preferred. Virtually any gear ratio can be realised for different centre distances by varying the number of teeth, the module and the addendum modification. Unlike straight teeth, helical teeth particularly help to reduce the noise level owing to the higher transverse contact ratio.
Spur wheels are generally manufactured by gear hobbing. Hardening treatment is also necessary if the drives will be subjected to heavy loads. The tooth flanks are subsequently ground to obtain high-quality spur wheels. Skive hobbing, where the hardened tooth flanks are remachined using special tools, is increasingly selected as an alternative to tooth flank grinding.
A wide range of materials is used to make spur wheels, for example case hardened steels, non-ferrous metals or plastics.

Pinions & motor shaftsPinions & motor shafts
Pinions & motor shafts
The driving force behind the gear
If the motor is directly connected to the gear, it is advisable to use a toothed motor shaft. This has the advantage of a short and compact design. The teeth of the motor shaft exhibit high true-running accuracy and hence excellent noise characteristics. They are cut directly into the motor shaft by gear hobbing and then hardened if necessary. If hardening distortion occurs following the heat treatment, the shaft is straighten in a further production step.
Alternatively, a separate pinion can be fabricated and pressed into a hole in the end of the motor shaft. In this case, only the pinion is hardened and there is no hardening distortion of the long shaft.

Ring gearsRing gears
Ring gears
Optimal blend of protection and functionality
Ring gears are essential design elements in the manufacture of planetary gears. Different production processes are used for the teeth depending on the volume to be manufactured and the quality requirements. Slotting is the method of choice for low to medium volumes. Since it is possible to make different numbers of teeth with one slotting tool, this method is very flexible.
Alternatively, the internal gear teeth can be manufactured by broaching. In contrast to slotting, only one defined inner profile can be realised because a fixed broach is used. However, broaching enables complex teeth to be made in a very short time, which is why an investment in expensive broaching tools is worthwhile for high volumes.

Planetary carriersPlanetary carriers
Planetary carriers
The hub of the planetary gear
A planetary carrier is the hub which holds the planets in the planetary gear. In the majority of applications the planets are mounted on bolts which are pressed into a planetary carrier with a single disc. Double-disc planetary carriers, where the axle bolts are held on both sides, prevent excessive elastic deformation due to the bolts bending at higher torques. These double-disc solutions are considerably more complicated, and hence more expensive, than the single-disc version because the pockets for the planets have to be machined as well.
If the available installation space is very short, the axle bolts are attached directly to the forging of the planetary carrier. These bolts cannot work loose accidentally owing to the adhesive bond.

Gear housingsGear housings
Gear housings
Protective element and interface
Gear housings are used to mount the bearings and form the interface with the load or drive side of the machine. Their job is simultaneously to protect the internal gear parts against the ingress of foreign particles and receive wear-reducing lubricants safely, as this will extend the lifetime of the gears. Gear housings can also serve to accommodate other functional elements such as rotary encoders or brakes.
Aluminium, steel or grey cast iron materials are used. When manufacturing prototypes or low volumes, the housings are cut from solid material on ultra-modern, multi-axis machining centres. For series production, on the other hand, they are normally made from castings.
The assembled gears are provided with a protective coating depending on the requirements for the drive.

Everything the gear needs to run smoothly
Various other parts are required for gears in addition to the gearwheels and the gear housing, the two main components. Numerous driving elements such as shafts, spacers, flanges, shift forks, brake discs, flywheels, couplings, levers and plates are generally necessary to enable the gear to perform all of the functions expected of it.
Once again, several different materials are used. The drive components are manufactured on modern lathes or multi-axis machining centres. Hardened parts are finished by hard turning, hard milling or grinding.

Materials handling
Materials handling
Whenever goods have to be transported, gears are generally inevitable. This is true both for vertical movements, for example with cranes or elevators, and for horizontal movements like those effected by industrial trucks or roller conveyors. Whereas a long service life and a rugged design always used to be at the top of the list of priorities, energy consumption and noise levels are decisive today. Good efficiency is vitally important for drives intended for continuous operation.

Professional tools
Professional tools
The drive components installed in professional tools are required to be compact and lightweight. The desired weight reduction can be achieved by using special-purpose gears and integrating several functions in one unit. The transition from mains to battery-operated tools often goes hand in hand with shorter operating times. This drawback can be compensated by choosing gears which were designed for optimum efficiency. Extreme environmental conditions moreover demand special bearing and sealing technologies, for which the gear design has to be adapted.

Medical technology
Medical technology
Modern medical technology would be unthinkable without advanced drive systems. The array of applications in the healthcare sector extends from devices for moving operating tables to drives for wheelchairs. Apart from being absolutely reliable, these drives are expected to run as quietly as possible and comply with strict hygiene regulations. The extra-smooth surfaces are made from stainless steels to facilitate cleaning.

Building services
Building services
The bulk of a building’s primary energy consumption is accounted for by the heating. Innovative drive systems for heating and ventilation regulate energy flows and noticeably reduce heat loss. Modern sun shading systems further improve the energy balance. The gears installed in these applications are durable and reliable. Access control is another increasingly important area alongside energy conservation, especially in buildings with high security requirements. Motor-operated security interlocks and access controls are considered a significant security upgrade in public buildings.

Electromobility
Electromobility
Electromobility is becoming more and more widespread as batteries are developed to last longer. E-bikes and electrically powered cars are growing in popularity. Apart from in the private sector, electromobility also plays a crucial role in industry in applications like forklift or driverless industrial trucks. The gears which are used for this purpose typically have high efficiency and a compact design.

Process technology
Process technology
Industrial processes are generally driven by mechanical components like pumps, agitators, mixers and crushers. Liquids are fed through tubes with the aid of valves and flaps. These components depend on motors and gears to do their job. A wide variety of substances are found here, many of them chemically aggressive, which means that corrosion-resistant materials are essential for the gears and geared motors. Drive components installed in hazardous areas additionally have to comply with ATEX regulations.
