摘要： A viscous coupling has an operating chamber in which: first and second (resistance) plates for transmitting torque therebetween are so arranged to be rotatable relative to each other, while spaced alternately with each other; and a viscous fluid is filled in the operating chamber, so that the resistance of the viscous fluid to rotation of the plates contributes to transmitting of torque between the first and the second plates. The coupling further comprises a plurality of spacer rings each of which is interposed between adjacent ones of the first or the second plates, each of which spacer rings is provided with an annular groove in which a peripheral portion of each of the second or the first plates is fitted, so that the first plates are surely spaced apart from the second plates through the spacer rings, whereby the hump torque is prevented from being produced in the coupling even when a difference in rotational speed between the first plates and second plate increases.
摘要翻译：粘性联轴器具有操作室，其中：用于在其间传递扭矩的第一和第二（电阻）板被布置为能够彼此交替地相对于彼此旋转; 并且粘性流体填充在操作室中，使得粘性流体对板旋转的阻力有助于在第一和第二板之间传递转矩。联接器还包括多个间隔环，每个间隔环插入在相邻的第一板或第二板之间，每个间隔环设置有环形槽，其中每个第二板或第一板的周边部分使得第一板通过间隔环可靠地与第二板间隔开，由此即使当第一板和第二板之间的转速差增加时，也避免了在联接器中产生驼峰扭矩。

摘要： The shortcomings inherent in prior art coupling fluids are eliminated by combining 1) a polyorganosiloxane fluid as the base oil with 2) sulfur or certain sulfur compounds and 3) at least one cyclic organosiloxane. These three ingredients form a suitable coupling fluid for use in viscous coupling systems.
