Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] figure 1 It is a structural schematic diagram of a pulley assembly provided by an embodiment of the present invention. Such as figure 1 As shown, the pulley assembly includes a first support plate 11 and a second support plate 12 arranged in parallel and facing each other, a support shaft 20 , a first pulley 31 , a second pulley 32 , and a spacer ring 42 .

[0022] The support shaft 20 is fixed on the first support plate 11 and the second support plate 12 , and the axis of the support shaft 20 is perpendicular to the first support plate 11 and the second support plate 12 . The first pulley 31 and the second pulley 32 are respectively coaxially sleeved on the support shaft 20 through two bearings 41 .

Abstract

The invention discloses a pulley assembly and belongs to the technical field of marine machinery and ocean engineering. The pulley assembly comprises a first supporting plate, a second supporting plate, a supporting shaft, a first pulley, a second pulley and a spacing ring, wherein the supporting shaft is fixed to the first supporting plate and the second supporting plate, and the axis of the supporting shaft is perpendicular to the first supporting plate and the second supporting plate; the first pulley and the second pulley are coaxially arranged on the supporting shaft in a sleeving mode through two bearings; the spacing ring is arranged on the supporting shaft in a sleeving mode and located between the first pulley and the second pulley; a first single-lip sealing ring is arranged between the first pulley and the first supporting plate, and a second single-lip sealing ring is arranged between the second pulley and the second supporting plate; and a double-lip sealing ring is arranged between the first pulley and the second pulley and installed on the spacing ring in a sleeving mode. Thus, the first pulley and the second pulley can be sealed through the double-lip sealing ring, and accordingly the pulley assembly can be prevented from being eroded by seawater, and the service life of the pulley assembly is prolonged.

Description

technical field [0001] The invention relates to the technical fields of marine machinery and marine engineering, in particular to a pulley assembly. Background technique [0002] The wave compensation system is a system used on marine supply ships to slow down the swaying of cargo with wind and waves during the supply process. [0003] The wave compensating system includes a compensating oil cylinder and a plurality of pulley assemblies, the plurality of pulley assemblies are respectively arranged at both ends of the compensating oil cylinder, and the pulley assemblies will reciprocate along with the expansion and contraction of the compensating oil cylinder. [0004] Due to the impact of sea waves, there is usually water on the deck, so that the pulley assembly is often wet by seawater when it is working, and sometimes even soaked in seawater. The existing pulley assembly usually includes a support shaft and a on a pulley. Such a pulley assembly is prone to rust and aging...
