RETAINER FOR PRINTED CIRCUIT BOARDS

A printed circuit board retaining device for use in securing a printed circuit board in an elongated slot of a rack provides an efficient design allowing for the utilization of an off-the-shelf screw in the device. A screw having a head located within a first end piece interconnects the first end piece, at least one elongated wedge, and a second end piece. A clutch assembly, also retained within the first end piece, is coupled to the screw by a tool configured to engage the screw head. The clutch assembly has a first and second clutch head.

ADJUSTABLE SPACER-CAM ASSEMBLY

Case 3365-00 ADJUSTABLE SPACER-CAM ASSEMBLY An adjustable spacer-cam assembly designed to close gaps which fall within a predetermined range of widths. The assembly includes: a cam plate which has a peripheral increasing-height ramp, a spring washer, and a threaded fastener. Serrations on the underneath surface of the fastener head engage serrations on the upper surface of the washer forming a friction clutch by which the cam plate is driven, Torque is transmitted from the washer to the cam plate by projections on the bottom of the washer which engage in apertures in the cam plate. The spacer-cam plate is driven until the ramp wedges between the members forming the gap causing the friction clutch members to slip.

NO-LASH TELESCOPING STEERING SHAFT

A no-lash telescoping steering shaft (10) comprises first and second telescopically arranged parts (12, 18) which are configured to transmit torque therebetween. The first and second parts carry an axially and radially movable locking piece (68) engaging the first and second parts at points which are axially spaced apart. The locking piece is coupled for axial movement with the inner of the two parts and frictionally engages the outer part to prevent relative axial movement thereof. Because the locking piece engages the first and second parts at axially spaced points, it creates a moment therebetween. The moment opposes side-to-side relative movement of the two parts in a first axial plane. The moment also urges cooperating surfaces (86, 88) of the two parts into engagement. The cooperating surfaces resist side-to-side relative movement of the two parts in a second axial plane which is substantially perpendicular to the first plane and also eliminate rotational lash from the steering shaft ...

SPOOL

WEAR ASSEMBLY

In a wear assembly for securing wear members to excavating equipment, a spool iis used with a wedge to hold the wear member in place. The spool is formed with at. least one laterally extending arm at its upper end in lieu of an axial arm such as useid in a conventional C-shaped spool. In this way, the spool can be easily supported in the assembly as the wedge is installed. The spool does not fall through the opening and no special care is needed to prevent it from falling. The spool also holds itself in place when the wedge is driven into the passage. As a result, installation of the wear assembly is easier and less hazardous. In addition, the lateral support reduces the risk that the spool will suffer spreading.

The tube sections are locked into position relative to each other by a packing washer (18) that is fitted around the inner tube section adjacent the open end of the outer tube and a locknut (16) that is fitted around a inner tube and is rotatably secured to the open end of the outer tube. The inner tube and the locknut are provided with complementary outer and inner non-circular surfaces so as to couple the two members together so that they rotate in unison. The locknut can be tightened down over the packing washer to secure the tube sections into position relative to each other by the simple act of either rotating the outer tube or the inner tube.

УЗЕЛ СМЕННЫЙ

Узел сменный для крепления сменных элементов к экскаваторному оборудованию, в котором для фиксации сменного элемента используется зажим с клином. Зажим образован по меньшей мере одним плечом, отходящим от его верхнего края в поперечном направлении, вместо продольного плеча, применяющегося в стандартных С-образных зажимах. Таким образом, в узле может быть легко обеспечена опора для зажима при установке клина. Зажим не выпадает через отверстие и не требуется специальных мер для предотвращения его выпадения. Зажим также остается на месте при введении клина в канал. В результате процесс установки сменного узла становится проще и представляет меньшую опасность. Кроме того, обеспечение опоры в боковом направлении снижает опасность растяжения зажима.

МОНТАЖНЫЙ УЗЕЛ

СЪЁМНОЕ СОЕДИНИТЕЛЬНОЕ УСТРОЙСТВО

Замок, содержащий клин, используемый для разъемного соединения вместе отдельных компонентов устройства. Клин может использоваться со вставкой. Клин и вставка соединяют посредством резьбы вместе для продвижения клина в или из отверстия в устройстве, не пользуясь при этом ни молотком, ни рычажным инструментом. Прямое соединение клина и вставки исключает необходимость использования болтов, прокладок, гаек и других элементов, что приводит к уменьшению компонентов в устройстве. Благодаря этому, замок не дорог в изготовлении, прост в использовании и мало подвержен риску утратить работоспособность из-за потерянных или сломанных частей или из-за частичек почвы или других трудностей, возникающих в тяжелых условиях землеройных работ. Кроме того, клин может вводиться в устройство для того, чтобы обеспечить степень затягивания, необходимую для предстоящей операции, и/или подтягивание устройства после возникновения некоторого износа в процессе работы.

Clamp-free clamping bandage

Die Erfindung betrifft einen Klemmverband (1, 2, 6) an einem Strebenelement, beispielsweise zur koppelnden Verbindung von Fahrwerksteilen mittels einer Lenk- oder Spurstange. Der Klemmverband verbindet ein Ende (5) der im Wesentlichen rohrförmigen Strebe (1) des Strebenelements mit einem Gewindebolzen (2), insbesondere zur Krafteinleitung in das Strebenelement. Erfindungsgemäß zeichnet sich der Klemmverband (1, 2, 6) durch eine im Endbereich (5) der rohrförmigen Strebe (1) in einem radialen Ringspalt zwischen dem Gewindebolzen (2q) und dem Innenquerschnitt der Strebe (1) in einem konischen Innengewinde (11) der Strebe (1) angeordnete Gewindehülse (6) aus, wobei die Gewindehülse (6) ein konisches Außengewinde (8) und ein den Gewindebolzen (2) aufnehmendes Innengewinde (12) aufweist. Die Gewindehülse (6) ist dabei zumindest im Bereich ihres strebenseitigen Endes (14) radial elastisch ausgebildet. Der erfindungsgemäße Klemmverband führt zu einer sicheren und dauerhaften Verbindung von Strebe und Gewindebolzen und vermeidet eine Schwächung der Strebenstruktur. Im Vergleich zu den im Stand der Technik gebräuchlichen Klemmschellen wird erheblicher Bauraum eingespart, bzw. Kollisionsgefahr mit angrenzenden Bauteilen vermieden. Die Strebe schwächende und Angriffsflächen für Korrosion bildende Anbringung von Schlitzen und/oder Nuten am Strebenende entfällt.

wear assembly

굴착 장비에 마모 부재를 고정시키기 위한 마모 조립체에서, 마모 부재를 제 위치에 유지하기 위하여 웨지와 함께 스풀이 사용된다. 스풀은 종래의 C-형 스풀에서 사용되던 것과 같은 축방향 암 대신에 그 상부 단부에 하나 이상의 측방향으로 연장하는 암을 구비하여 형성된다. 이러한 방식으로, 스풀은 웨지가 설치될 때 조립체 내에 용이하게 지지될 수 있다. 스풀은 개구를 통해 떨어지지 않으며, 스풀이 떨어지는 것을 방지하기 위해 특별히 주의를 기울일 필요가 없다. 스풀은 또한 웨지가 통로 내부로 밀어 넣어질 때 자신을 제 위치에 유지시킨다. 결과적으로, 마모 조립체의 설치가 더 쉬워지며 덜 위험하게 된다. 또한, 측면 지지는 스풀이 벌어지게 되는 위험을 감소시킨다. 마모 조립체, 굴착용 장비, 웨지, 스풀 In a wear assembly for securing a wear member to an excavation equipment, a spool is used with a wedge to hold the wear member in place. The spool is formed with one or more laterally extending arms at its upper end instead of the axial arm as used in conventional C-shaped spools. In this way, the spool can be easily supported in the assembly when the wedge is installed. The spool does not fall through the opening and no special care is required to prevent the spool from falling. The spool also keeps itself in place as the wedge is pushed into the passageway. As a result, the installation of the wear assembly becomes easier and less dangerous. The side support also reduces the risk of spool opening. Wear assemblies, excavation equipment, wedges, spools
