Abstract

A rotary viscous brake for a hose reel (10), and a hose reel (10) with the same, is disclosed. The rotary viscous brake (50) comprises a first part (100) attachable to a housing (20) of the hose reel (10), a second part (200) attachable to a rotatable drum (30) for a hose on the hose reel (10), and a third part (300) for enclosing the second part (200) within the first part (100) and third part (300) together with a liquid (400). The first part (100) comprises a plurality of first fins (110) being circumferential and extending in an axial direction of the rotary viscous brake (50). The second part (200) comprises a plurality of second fins (210) being at least partly circumferential and extending in an opposite axial direction of the rotary viscous brake (50). The plurality of first fins (110) and second fins (210) are arranged such that they are interleaved with each other and immersed by the liquid (400) for providing a damping torque when the first part (100) and the second part (200) rotate relatively to each other. There are at least two second fins (210) next to each circumferential first fin (110); and a thickness (220) of each of the second fins (210) is gradually increased from a thinner end (212) to a thicker end (214).
