Compatibility: The compatibility of parallel keys DIN 6885 form A ensures they can be used with a wide range of shaft and hub configurations. They are available in various sizes, allowing flexible adaptation to specific shaft diameters and keyway widths. Selecting the right size and specification is crucial to ensure optimal fit and thus reliable performance of machine elements. It is also important to ensure compliance with other relevant standards and application-specific requirements to guarantee full compatibility and performance.

4. Advantages and Benefits

Reliable power transmission: Thanks to their precise manufacturing and specific shape, parallel keys fit seamlessly into the corresponding keyways of the shaft and hub. This ensures optimal power transmission and prevents twisting or slipping under load. Form A, with its specific profile, provides even better load distribution and transfer.

Easy installation and removal: One of the main features of parallel keys is their simplicity in installation and removal. No special tools or procedures are required, which saves time and costs, especially during maintenance and repair work. This accessibility also makes it easy to inspect and replace parallel keys when worn, without damaging the shaft or hub.

High adaptability: Parallel keys DIN 6885 form A are available in a wide variety of sizes and materials, allowing their use in different mechanical configurations and operating environments. From light-duty applications to high-performance uses in industry - there is a suitable parallel key for almost every requirement.

Durability: Manufactured from high-quality key steel according to DIN 6880 or stainless steel, parallel keys offer high strength and corrosion resistance. This contributes to a long service life, even in demanding environments such as outdoors or in applications exposed to chemicals.

Cost efficiency: In addition to their high performance and reliability, parallel keys are a cost-effective solution for power transmission. Their simple installation and the possibility of reuse further help reduce overall costs.

Overall, parallel keys DIN 6885 form A not only provide a reliable solution for connecting machine elements, but also improve the efficiency and cost-effectiveness of the design and maintenance of machines and systems, making them a preferred choice for engineers and designers worldwide.

5. Assembly and Installation

Tools and preparation:

Make sure you have all the necessary tools at hand, including appropriate protective equipment.
Check the dimensions of the shaft, hub, and parallel key to ensure they fit together.
Thoroughly clean the keyway of the shaft and the hub to remove dirt and corrosion. This ensures a good fit and optimal performance.

Inserting the parallel key:

Carefully place the parallel key into the slot on the shaft. The parallel key should fit into the slot without being too loose or too tight. Light tapping with a plastic hammer may be required to fully insert it, but be careful not to damage the parallel key.
Ensure that the parallel key is flush with the shaft or slightly below the surface to allow the hub to slide on smoothly.

Mounting the hub:

Slide the hub over the end of the shaft so that the slot of the hub is aligned with the parallel key.
It may be necessary to use slight pressure or gentle hammer blows to bring the hub into the correct position on the shaft. Again, it is important to avoid damage from excessive force.

Final inspection and alignment:

After assembly, check the alignment of the shaft and hub to ensure the connection is correct and the parallel key serves its function.
Perform a visual inspection to make sure that no part of the parallel key is protruding or that there are other signs of faulty installation.

Maintenance:

After assembly, it is advisable to regularly check the parallel key connection for wear or loosening, especially in applications exposed to high loads or vibrations. A careful assembly process ensures that the parallel key serves its intended purpose efficiently and ensures a long service life of the connection.

6. Safety instructions & Standards

Within the design and assembly of machine elements, such as parallel keys DIN 6885 form A, adherence to safety instructions and standards is crucial to prevent accidents and ensure a high level of reliability and performance of mechanical connections.

DIN 6885: This standard defines the shapes, dimensions, and tolerances of parallel keys used for connections between rotating elements and shafts. Compliance with this standard ensures that the parallel keys are universally applicable and interchangeable, which improves compatibility and performance in assembly.

Frequently Asked Questions (FAQ)

What are parallel keys DIN 6885 form A?

Parallel keys DIN 6885 form A (round-ended, high-sized version) are mechanical linking elements that enable a reliable, non-rotatable connection between a shaft and a hub, allowing torque to be transmitted and preventing relative rotation.

What is the difference between parallel keys DIN 6885 form A (round-ended, high-sized version) and the parallel keys DIN 6885 form B (straight-ended, high-sized version)?

The main difference lies in the design of their end faces:

Round-ended (form A): Parallel keys DIN 6885 form A have rounded ends on both sides. This rounding facilitates installation, as it fits into the corresponding curves of the keyway openings in the shaft and hub. The round end form is suitable for applications where easy assembly and disassembly are required, and where the parallel key connection does not need to be released frequently.
Straight-ended (form B): In contrast, parallel keys DIN 6885 form B have straight end faces. These straight ends fit into keyways with a correspondingly right-angled opening. Parallel keys with straight ends can enable better power transmission in certain applications, especially when high torques are involved or when a more precise positioning of the parallel key is needed.

Both forms are available in a high-sized version, which indicates their relative thickness and thus their ability to transmit power. The choice between these two forms depends mainly on the specific application, the requirements for assembly and disassembly, and the configuration of the shaft-hub connection.

Which dimensions are available for parallel keys DIN 6885 form A?

The sizes vary from A 2x2x6 to A 100x50x400, with widths from 2 to 100 mm, heights from 2 to 50 mm, and lengths from 6 to 400 mm.

What material are parallel keys DIN 6885 form A typically made of?

Parallel keys compliant with this standard are usually made of key steel DIN 6880 or stainless steel and feature a bright surface.

In which areas of application are parallel keys used?

Parallel keys are used in a wide range of fields such as mechanical engineering, agricultural technology, vehicle construction, wind power, and automation technology to secure critical connections, such as in gearboxes, couplings, and drive shafts.

What are the advantages of parallel keys DIN 6885 form A?

They offer reliable power transmission, easy assembly/disassembly, high adaptability thanks to various sizes and materials, durability due to high-quality materials, and cost efficiency.

How does form A specifically contribute to the performance of the parallel keys?

The specific form A, with its profile, improves load distribution and power transmission by fitting seamlessly into the corresponding slots of the shaft and hub.

What safety instructions and standards must be observed when using parallel keys DIN 6885 form A?

It is essential to observe safety instructions such as wearing protective equipment and using the correct tools, as well as complying with the DIN 6885 standard for shapes, dimensions, and tolerances.

How is the assembly of a parallel key according to DIN 6885 form A carried out?

Assembly involves precisely inserting the parallel key into the slot on the shaft and fitting the hub so that the slot in the hub is aligned with the parallel key, followed by final inspection and alignment of the assembly.

Why is the correct selection of size and material for parallel keys important?

A correct selection ensures an optimal fit and functionality of the machine elements, is crucial for compatibility with other components, and meets the specific requirements of the application.

How does the easy assembly and disassembly of parallel keys contribute to cost-effectiveness?

By avoiding special tools or procedures, time and costs are saved, especially during maintenance and repair work, which reduces overall costs and improves efficiency.
