MAV 2005
The document provides technical specifications for the MAV 2005 Standard Series locking assemblies, which are used for gear wheel connections. These assemblies are characterized by medium capacity, non-self-centering, and non-self-locking features. They maintain a fixed axial hub position during tightening and include two thrust rings with a double taper design. The assemblies have low axial dimensions and specific tolerance requirements for the shaft and hub bore.
- Medium capacity locking assemblies.
- Not self-centering or self-locking (self-releasing).
- Fixed axial hub position during tightening.
- Two thrust rings with double taper design.
- Low axial dimension.
- Tolerances: Shaft h7-h11; Hub bore H7-H11.
- Surface finish of shaft and hub bore: Ra < 3.2 µm.
The locking assemblies consist of a slotted inner ring, a slotted outer ring, a double taper front thrust ring with integrated pull-out threads, a double taper rear thrust ring, and a set of socket head cap screws (grade 12.9). Zinc-plated screws indicate the position of pull-out threads.
The document includes detailed tables listing dimensions, screw sizes, and performance metrics such as:
- Ma: Screws tightening torque (Nm).
- Mt: Transmissible torque with Fax=0 kN (Nm).
- Fax: Transmissible axial load with Mt=0 Nm (kN).
- Ps: Contact pressure on shaft (MPa).
- Ph: Contact pressure in hub bore (MPa).
The document provides application examples for different sizes, indicating their suitability for various industrial uses based on their dimensions and performance characteristics.
