专利名称：CLUTCH申请号：JP13750879申请日：19791024公开号：JPS5743767B2公开日：19820917专利内容由知识产权出版社提供摘要：An electromagnetically operated friction clutch is disclosed of the type including an axially movable armature member which is drawn into frictional driving engagement with a friction surface on an inner body to establish drive through the clutch, in which a torque overload deenergization of the electromagnetic coil is provided. The clutch is provided with a torque boosting arrangement in which the drive from the axially movable armature is transmitted through a series of balls disposed in corresponding pockets formed in a radial face of the armature and an opposing radial face of a clutch element drivingly connected to one of the primary clutch members. The action of the balls in the pockets creates a torque boosting effect increasing the engagement pressure exerted on the frictional engagement surfaces. The torque overload release arrangement includes mounting of the clutch element axially and rotationally so as to be restrained by means of a spring element. The axial movement of the clutch element against the spring bias in response to the transmission of a particular level of torque is employed to sense a torque overload condition, and by positioning a microswitch activated by a predetermined extent of axial movement of the clutch element, the electromagnetic coil is deenergized at a predetermined torque level. The clutch may be reenergized at high speed by a manual switch reenergizing the coil relay which draws the friction surfaces into engagement.更多信息请下载全文后查看。

(54)Title:TRENCHCOVER WITH RETAINER
gure1
(57)Abstract:A trenchcover comprises a panel(10)adapted to extend over a trench,hole,cavity or the like.The panel(10)is of sub¬stantially square or rectangular shape defining longitudinal and lateral axes(16,18),and comprises a plurality of retainer arrangements (22)secured to the panel(10),wherein each retainer arrangement(22)comprises a housing(24)holding captive a row of retainer pins (34)each of which is moveable between a retracted position and an extended position.Each pin(34)projects from the underside of the panel(10)when in its extended position.The row of retainer pins(34)is angled to both the longitudinal axis(16)and the lateral axis
TRENCHCOVER WITH RETAINER
This invention relates to a trenchcover intended for use in covering a trench,hole,cavity or the like formed in a footpath or road surface,and in particular to a trenchcover with a retainer operable to resist sliding movement of the trenchcover relative to the ground surface once positioned over such a trench,hole,cavity or the like.
GB2476873describes a trenchcover arrangement in which a series of covers are arranged to be positioned side-by-side so as to cover an elongate trench.The underside of each trenchcover,or at least some of the trenchcovers,is provided with a retainer arrangement operable to resist movement of the cover relative to the ground surface upon which the trenchcovers are supported.The retainer arrangements comprise pins or fingers moveable between raised or retracted positions in which they are located within, and do not project from the underside of,the trenchcovers,and lowered or extended positions in which they project from the underside of the trenchcovers.
In use,a trenchcover with the retainer arrangement fitted thereto is positioned over part of a trench to be covered.Those of the pins or fingers which overlie the trench move under the action of gravity to their extended positions,whilst those over the ground surface remain in substantially their retracted positions.The extended pins or fingers closest to the sidewalls of the trench are able to bear against the adjacent sidewall,thereby resisting longitudinal movement of the trenchcover.
Whilst the arrangement described in GB2476873operates effectively,providing resistance to undesired movement of the trenchcover without requiring a significant amount of work on the part of the operator as the appropriate pins or fingers move automatically to their operative positions upon positioning of the trenchcover,the arrangement does have the disadvantage that the resistance to movement is directional in the sense that only。
