Abstract:
A clutch bearing (34) for a transportation refrigeration unit includes one or more rolling elements (38) supportive of one or more components of an electromagnetic clutch for a transportation refrigeration unit, and a plurality of bearing races (36) configured to retain the one or more rolling elements. The bearing races include a coating of thin dense chromium to reduce corrosion and/or damage of the clutch bearing. A transportation refrigeration unit includes a power source (12) and a blower (32) of the transportation refrigeration unit. An electromagnetic clutch (14) is operably connected to the power source and the blower (132) and includes a rotor (16) positioned at a central axis and an armature (18) positioned at the central axis and having an axial air gap (22) to the rotor when the clutch is in a disengaged position. A clutch bearing is located at the central axis and is supportive of the rotor.
Abstract:
A bearing arrangement includes a bearing outer element that defines a first plurality of races opening radially inwardly, a bearing inner element that defines a second plurality of races opening radially outwardly, and a bearing middle element defining a third plurality of races at its radially outer surface thereof and a fourth plurality of races at its radially inner surface thereof. Rolling elements are receivable in the races. The bearing middle element includes an axial protrusion at least at one end thereof that can be received in a housing with respect to which the bearing outer and inner elements are rotatable.
Abstract:
This ball bearing (1) forms an axial force transmission member and comprises an inner ring (3) and an outer ring (4), and a single series of balls (6) placed in a rolling chamber between the inner ring (3) and the outer ring (4). A first ring (4), amongst the inner ring (3) and the outer ring (4), forms a travel track (411) in a section of a sphere centred on a geometric point (C4) belonging to an axis of symmetry (X 4 ) of this first ring (4). The first ring (4) supports a seal (11 ) insulating the rolling chamber relative to the outside. The second ring (3), amongst the inner ring (3) and the outer ring (4), is provided with a sealing zone (314) designed to interact with the seal and in the shape of a section of a sphere centred on a second geometric point (C 3 ) belonging to an axis of symmetry (X 3 ) of the second ring. The radii (R 3 , R 4 ) of the sections of a sphere are different. In the installed configuration of the bearing, the first geometric point (C 4 ) and second geometric point (C3) are superimposed and offset axially, along the axis of symmetry (X 3 ) of the second ring (3), relative to the series of balls.
Abstract:
The invention relates to a clutch release bearing comprising a first raceway (1) which is designed as a flat annular disk, a second raceway (2) which is also designed as a flat annular disk, rolling elements (W) that are accommodated in a raceway space (B) defined between the first raceway and the second raceway, and a cage structure (3) that is defined by an annular element, said annular element comprising on its periphery a series of rolling element windows for guiding the rolling elements inside the raceway space. The clutch release bearing is characterized in that a wedge chain is designed in the outer edge section of the annular element and comprises a plurality of subsequent wedges (K1, K2, K3), with lubricant passages being defined to allow lubricant to pass. Every wedge is delimited on the exterior by a wedge exterior wall (K1a, K2a, K3a) and on the interior by a wedge interior wall and forms a wedge tip (K1s, K2s, K3s) pointing in a main direction of travel (LR) of the bearing, the annular element, in the area of the wedge tip, having a cut-out section (D1, D2,D3) that is open towards the exterior and reaches under the wedge tip.
Abstract:
Die Erfindung bezieht sich auf ein Axiallager, insbesondere ein Kupplungsausrücklager. Der Erfindung liegt die Aufgabe zugrunde, Lösungen zu schaffen durch welche es möglich wird, ein insbesondere als Kupplungsausrücklager geeignetes Axiallager zu schaffen das in fertigungstechnischer Hinsicht kostengünstig herstellbar ist und das sich durch eine lange Lebensdauer auszeichnet. Diese Aufgabe wird erfindungsgemäß gelöst durch ein Axiallager mit einem ersten Lagerlaufring der als flache Ringscheibe ausgeführt ist, einem zweiten Lagerlaufring der ebenfalls als flache Ringscheibe ausgeführt ist, Wälzkörpern die in einem zwischen dem ersten Lagerlaufring und dem zweiten Lagerlaufring definierten Bahnraum aufgenommen sind, und einer Käfigeinrichtung zur Führung der Wälzkörper innerhalb des Bahnraumes, wobei sich dieses Axiallager dadurch auszeichnet, dass an dem ersten Lagerlaufring im Außenumfangsbereich ein erster Ringsteg ausgebildet ist, und dass an dem zweiten Lagerlaufring ebenfalls im Außenumfangsbereich desselben ein zweiter Ringsteg ausgebildet ist, wobei beide Ringstege so zueinander radial versetzt angeordnet und dimensioniert sind, dass sich diese in einem den Bahnraum umsäumenden Umfangsbereich unter Belassung eines Laufspaltes überlappen. Dadurch wird es auf vorteilhafte Weise möglich, ein insbesondere als Kupplungsausrücklager geeignetes Axiallager zu schaffen, das sich durch eine äußerst geringe axiale Bautiefe auszeichnet und bei welchem eine besonders wirkungsvolle Abkapselung des die Wälzkörper aufnehmenden Wälzkörperbahnraums erreicht wird.

Abstract:
The invention relates to a sleeve-type free-wheel with bearing consisting of a cylindrical sleeve (1) having a sleeve edge (2) at each end with a clamping surface applied to an inner or outer side of the sleeve (1), a centrally guided free-wheel cage (3) with spring-loaded means (4) to accept grip rollers (5) and bearing cages (6) with bearing rollers (7) on both sides thereof. According to the invention, between the free-wheel cage (3) and the bearing cage (6) and/or between the inner side of the sleeve edge (2) and the face of the bearing cage (6) there are apertures (8) communicating with chambers for lubricant (11). The aim of the invention is also achieved in another embodiment in that, in the region of the web of the free-wheel cage (3) and/or bearing cages (6), lubricating wells are located between the grip rollers (5) and/or the roller bearings (7). The design of the sleeve-type free-wheel of the invention provides sufficient lubrication for the running surfaces, thus improving the efficiency and extending the life of the sleeve-type free-wheel.
Abstract:
The invention is comprised of first (10, 60, 110) and second gear members forming a gear pair, one of which is connected to an input shaft (11, 61, 111), the other of which is connected to an output shaft, such that rotational energy from the input shaft (11, 61, 111) is transferred through the respective gear members to the output shaft. Either the first gear member, the second gear member, or both, is manufactured in two parts, an inner member (12, 62, 112) and an outer member (22, 72, 122), the inner member (12, 62, 112) connected to the respective input (12, 62, 112) or output member (22, 72, 122), the outer member (22, 72, 122) defining the gear teeth (13, 63, 126). The inner member (12, 62, 112) defines a subderivative hyperboloidal inner race surface of revolution (14, 64, 114) about the axis of rotation of the gear member (10, 60, 110). The outer member (22, 72, 122) defines a superderivative hyperboloidal outer race surface of revolution (24, 74, 144) about the axis of rotation of the gear member (10, 60, 110). The inner and outer race surfaces are disposed in confronting relationship and define an annular circumferential volume therebetween separating the inner and the outer members. A plurality of thrust transmitting cylindrical rollers (28, 78, 128) are disposed in said volume.
Abstract:
A self-adjusting engine clutch control cable comprising a movement-transmitting core (1) sliding within a guiding conduit (2) is provided with a self-adjustment device comprising a clamp (3) for releasably connecting one end portion of the conduit (2) to an abutment (4). A clamp component (5) is connected to one end portion of the conduit (2) by a slip-coupling (9). When a load (29) is applied to the core (1) by depression of the clutch pedal, movement of that end portion of the conduit is transmitted to component (5) via the slip coupling. Jaw elements (17, 18) of that component (5) close onto that conduit portion while permitting it to advance in the clamp against biasing spring (27). On its release, that conduit portion moves back to a position depending on the action of spring (27) and on any end-of-cycle cable loading imposed by the clutch clamping spring as a result of clutch wear.
