A method for preparing titanium alloy that is created to be formed into a bearing component, wherein the titanium alloy comprises from 5 to 7 wt % Al, from 3.5 to 4.5 wt % V, from 0.5 to 1.5 wt % Mo, from 2.5 to 4.5 wt % Fe, from 2.5 to 4.5 wt % Fe, and from 0.05 to 2 wt % Cr. The alloy can optionally include one or more of the following elements: up to 2.5 wt % Zr, up to 2.5 wt % Sn, and up to 0.5 wt % C. The balance of the composition comprises Ti together with unavoidable impurities. The alloy is heated to a temperature T below the (α+β/β)-transition temperature Tβ and then quenched. The alloy is then aged a temperature of from 400 to 600° C.

A spherical plain bearing includes an outer ring (4) formed from metal and having a concave first bearing surface, and an inner ring (12) having a convex second bearing surface in sliding disposition to the first bearing surface. One of the rings is made from titanium alloy and has a treated bearing surface (18). The other bearing surface (16) has a lubrication liner (20). The liner may be made from PTFE, such as a fabric of PTFE and polyaramid fibers. The treated surface may be TiN provided by physical vapor deposition.

The bearing rings 1 and 2 of a rolling bearing is formed of one kind of titanium alloys of β type titanium alloys, near β type titanium alloys and α + β type titanium alloys. The titanium alloy has a surface hardness of Hv 400 or more and less than Hv 600 for increasing the corrosion resistance and wear resistance of the bearing ring. Spherical rolling elements 3 rolling on the raceway surfaces 1a and 2a of the bearing rings 1 and 2 are formed of ceramics such as silicon nitride. When β type titanium alloys or α + β type titanium alloys after a solution treatment and applied with an oxidation treatment at a low temperature of 400 to 600°C are used as the material for the bearing ring, a bearing ring made of titanium alloy suitable to use under a circumstance requiring corrosion resistance is obtained.

The present invention relates to a mirror mount (10). In particular, the present invention relates to a two-axis mirror flexure mount with increased stiffness in all but the desired degrees of freedom. The present invention recites an integrally formed support (10) for a mirror comprising; a rigid portion (40); a plurality of base portions (30) suitable for mounting the mirror thereto; and a plurality of substantially linear flexure elements (20) provided substantially perpendicular to one another and disposed between the rigid portion (40) and the base portion (30) to connect the rigid portion (40) and the base portion (30) together; wherein the flexure elements (20) each define an axis of rotation and are operable to allow the rigid portion to rotate relative to the base portion along either said axis of rotation.

A bearing arrangement (50) comprises first and second bearings (52, 62). Each bearing comprises a respective support element (54, 64) and a respective set of rolling elements (53, 63) and defining a respective load path (57, 67) extending through the respective support element and rolling elements. The support elements are coupled such that a load applied to either support element is transmitted through both the first and second load paths. The arrangement further comprises a pair of superelastic titanium alloy elements (58, 68) located in the respective load paths to provide resilient movement between the bearings when a load is applied to the bearing arrangement.

摘要:
Race rings wheels (1,2) of a rolling bearing are formed of any one titanium alloy of beta , near beta , and alpha + beta titanium alloys. Titanium alloy has a surface hardness of Hv400 to Hv600 to enhance the corrosion resistance and wear resistance of the race rings wheels. A roller (3) which rolls over the race faces (1a,2a) of the race rings (1,2) is formed of a ceramic such as silicon nitride. Use of beta titanium alloy or alpha + beta titanium alloy subjected to solution treatment and oxidized at a low temperature of 400 to 600 DEG makes it possible to produce race rings made of titanium alloy preferable to use in the environment which require corrosion resistance.
