The present disclosure is directed to a clamping apparatus for securing a main bearing of a wind turbine. The clamping apparatus includes a clamp member configured for securement to a seal ring arranged with the main bearing, at least one clamping fastener configured through the clamp member, and at least one jacking fastener configured through the clamp member. Thus, the clamping fastener is configured to tighten the clamp member around the seal ring, whereas the jacking fastener is configured to push against the main bearing when tightened so as to maintain the main bearing in place during and installation and/or repair procedure.

A composite structural component made of a polymer matrix composite material includes an end connection that includes an end portion at one end of the composite structural component, comprising an internal surface comprising a plurality of ridges and grooves defining a first engagement surface along an axial direction and a metal interface component comprising an outer surface comprising a plurality of ridges and grooves defining a second engagement surface along the axial direction and an inner surface defining a mounting surface for attachment of an end fitting. The metal interface component is engaged with the internal surface of the composite structural component by mating of the first and second engagement surfaces. The structure also includes an outer annular component fitted around the end portion in axial alignment with the mating of the first and second engagement surfaces.

A temperature compensation ring configured to compensate for a temperature-dependent distance change between two components includes a base body made from an elastic material, and at least a section of at least one surface of the base body is configured to reduce a friction in the axial direction between the temperature compensation ring and an abutment surface, by, for example, being coated with a friction reducing coating and/or by including one or more grooves for receiving a lubricant.

A bearing unit having a stationary radially outer ring, a radially inner ring rotatable about a central rotation axis (X) of the bearing unit is provided with at least one raceway and, in an end portion thereof, with at least two circular sector segments, at least one row of rolling elements interposed between the radially outer ring and the radially inner ring, and a concentric collar for clamping the radially inner ring on a rotating shaft, where an induction-hardening heat treatment is applied to a portion of the radially inner ring that overlaps with at least a portion of the at least one raceway.

In a rolling bearing in which one of inner and outer rings is a rotary ring and the other is a stationary ring, a fitting surface of the stationary ring fitted to a mating member is formed in first and second partial peripheral surfaces of a radially outer surface of the stationary ring which faces the mating member. The first partial peripheral surface is formed on one side in the axial direction, and the second partial peripheral surface is formed on the other side in the axial direction with respect to the first partial peripheral surface. An annular groove that restrains creep is formed between the first partial peripheral surface and the second partial peripheral surface. The annular groove has a depth that is large enough not to allow the bottom of the annular groove to contact the mating member when a radial static rated load is applied.

An improved mechanical joint that remains together under combined vertical, angular and torsional loads, provides vibrational isolation to the stresses experienced and transmitted by any connected members, offers increased angular movement at the joint, and will allow torsional movement. It has its primary use in the automotive industry to connect the control arms to the steering knuckles of an automobile, although they have a plethora of other mechanical applications such as in the movable joints of dolls.

Grinding is performed on an outer peripheral surface of a shaft member while rotationally driving the shaft member under a state in which both end surfaces of the shaft member are sandwiched between a pair of support portions. A convex surface is formed on one axial end surface of the shaft member or an end surface of one of the pair of support portions, and a flat surface is formed on the other of the one axial end surface of the shaft member and the end surface of the one of the pair of support portions. The flat surface and an apex of the convex surface are brought into contact with each other to support one axial end portion of the shaft member.

The invention provides a fixed rolling element bearing assembly comprising: a housing; an inner race for attaching to a rotating shaft; a cage and rolling element assembly positioned around the inner race; first and second positional locators for positioning the cage and rolling element assembly between inner edges thereof; a thrustwasher adjacent an outer edge of either of the first or second positional locator and fixably connected to the housing.

A parking cable has a plurality of plastic split type liners, which reduces frictional resistance between the inner cable and a conduit among the components of the parking cable. The plurality of split type liners is press-fitted and disposed to a desired position in an inner diameter of the conduit. The plastic split type liners may serve as a guide that ensures force for smoothly moving the inner cable and also improve in-line assembly properties. A method of manufacturing the parking cable includes press fitting the plurality of split type liners between the inner cable and the conduit.

The invention relates to a split bearing arrangement (1) with a bearing block (2) comprising counter clamping surfaces (5) and a bearing cover (3) comprising clamping surfaces (4), wherein the bearing cover (2) is connected to the bearing block (3) by means of bolt-like connecting elements mounted in bores (8) in the clamping surfaces (4) and/or comprising at least one projection (13) per clamping surface (4), which can be pushed into the counter clamping surface (5) of the bearing block (2), wherein the clamping surfaces (4) of the bearing cover (2) or the counter clamping surfaces (5) of the bearing block (2) are oriented obliquely at an angle not equal to 90 to the longitudinal extension of the connecting elements and/or the projections (13) are arranged respectively at a distance (16) of at least 150% of a maximum height (17) of the projections (19) over the clamping surfaces (4) from the bore (8) and/or a side wall of the bearing cover (3).
