Embodiment Construction

[0031] will now refer to Figure 1 to Figure 3 The torque protection device of the present invention and the torque transmission mechanism of the present invention are described.

[0032] figure 1 A cross-sectional view is shown of a safety hub 1 as a first embodiment of the torque protection device of the invention and a part of a gearbox 3 with an annular coupling 5 and an epicyclic train represented by element 7 in an exemplary manner. The gearbox 3 is connected to a drive shaft (not shown), such as a gas turbine, to convert the rotational frequency of the drive shaft to a lower rotational frequency.

[0033]The safety hub 1 , which is firmly connected to the ring coupling 5 of the gearbox 3 , comprises a drive element 9 with a drive element body 11 and a driven element 13 with a driven element body 15 . It is fixed to the ring coupling 5 via the drive element 9 . Thus, drive torque is transmitted from the ring coupling 5 of the gearbox 3 constituting the drive input mem...

Abstract

A torque protection device (1) is disclosed with an axial direction, a radial direction, a driven element (13) for connecting the torque protection device (1) to a driven output member, a driving element (9) for connecting the torque protection device (1) to a driving input member, and at least one shear pin (17) connecting the driving element (9) to the driven element (13) and having a first end (35) held by the driven element (13) and a second end (25) held by the driving element (9).The shear pin (17) extends from the driven element (13) to the driving element (19) in radial direction of the torque protection device.

Description

technical field [0001] The invention relates to a torque protection device having an axial direction, a radial direction, a driven element for connecting the torque protection device to a driven output member, for connecting the torque protection device to a drive A drive element of the input member, and at least one shear pin having a first end retained by the driven element and a second end retained by the drive element. The invention further relates to a torque transmission assembly comprising a torque protection device. Background technique [0002] A torque protection device like eg a safety hub is used for torque protection when torque is transmitted from the driving member to the driven member. Typically, a torque protector connecting a driving member to a driven member is designed to transmit torque within a specific range. When the maximum torque is exceeded, the torque protection device may be damaged if too much load is transferred from the driving member to the...
