US Patent:

6764219, Jul 20, 2004

Filed:

Apr 2, 2002

Appl. No.:

10/114832

Inventors:

Gary L. Doll - Canton OH
Gerald P. Fox - Massillon OH

Assignee:

The Timken Company - Canton OH

International Classification:

F16C 1936

US Classification:

384565, 384492, 384571

Abstract:

A full complement antifriction bearing includes an inner race, an outer race, and rolling elements organized in a circular row between the races without a cage or retainer for separating the rolling elements. While the absence of a cage or retainers enable the bearing to have the maximum number of rolling elements and thus transfer greater loads, adjacent rolling elements contact each other. Each rolling element or every other rolling element is covered with a tribological coating that retards adhesive wear and reduces friction.

Assignee:

The Timken Company - Canton OH

International Classification:

F16H 57/08

US Classification:

475335, 475348

Abstract:

An epicyclic gear system has a sun gear, a ring gear, and planet gears between the sun and ring gears. In addition, it has a carrier including a carrier flange offset axially from the planet gears and carrier pins that project from the flange into the planet gears, each with a shank anchored to the flange, a head remote from the flange, and a groove between the shank and head. Between the planet gears and the carrier pins are bearings, each including an inner race and rollers between the inner race and planet gear. Whereas the carrier pins are cantilevered from the carrier flange, the inner races are cantilevered from the heads of the carrier pins. The grooves in the pins enhance pin deflection, so that the axes about which the planet gears rotate remain parallel to the central axis of the system.

International Classification:

F16H 57/08

US Classification:

475348

Abstract:

An epicyclic gear system (A) has a sun gear (), a ring gear () located around the sun gear, and planet gears () located between and engaged with sun and ring gears. In addition, it has a carrier () including a carrier flange () offset axial from the planet gears, carrier pins () projecting from the carrier flange into the planet gears, and bearings () between the planet gears and the carrier pins so that the planet gears rotate on the pins. Each bearing includes an inner race () having tapered raceways () presented away from the carrier pin, opposing tapered raceways () on the ring gear, and tapered rollers () organized rows between the raceways. Whereas the carrier pin is cantilevered from the carrier flange, the inner race is cantilevered from the carrier pin remote from the carrier flange, and this insures that the axes (Y) about which the planet gears rotate remain parallel to the central axis (X) of the system.

International Classification:

US Classification:

295 42, 384459, 384584

Abstract:

A backing ring that serves to back an antifriction bearing on the journal of a rail car axle includes an annular body that seats against a fillet that is located at the end of the journal and also a lip that projects over a larger dust guard diameter that is located on the axle immediately beyond the fillet. In addition, the backing ring includes a stabilizing element which cooperates with the lip and with the dust guard diameter to lessen the tendency of the annular body to work against the fillet and create a fretting wear when the journal undergoes cyclic flexures. The stabilizing element accommodates dust guard diameters of varying size. The stabilizing element may also establish a seal between the lip and the dust guard diameter.

Inventors:

Gerald P. Fox - Massillon OH, US

Assignee:

The Timken Company - Canton OH

International Classification:

F16H 1/48

US Classification:

475331, 475346, 475348

Abstract:

An epicyclic gear system (A, B), which is highly compact, yet capable of transferring substantial torque, includes a sun gear (), a ring gear () around the sun gear, and planet gears () organized in two rows between the sun and ring gears. In addition, the gear system has a carrier () provided with one or two flanges () and flexible pins () around which the planet gears revolve. The planet gears are mounted on the pins in a double cantilever arrangement to improve the mesh with the sun and ring gears and achieve better load distribution.

US Classification:

475343, 74665 GD, 416170 R

Abstract:

A transmission for a wind turbine includes a housing () in which two shafts () rotate, each being supported on a locating bearing () which transmits thrust loads to the housing as well as radial loads and on a nonlocating bearing () which transmits only radial loads to the housing. The shafts carry helical gears () which induce thrust loads in the shafts when the shafts transmit torque. The locating bearings are unitized single row tapered roller bearings which are oriented to transmit thrust loads in the primary direction through their raceways () and in the secondary direction through ribs () at the ends of their rollers (). The nonlocating bearings take the form of a single row cylindrical roller bearings which accommodate differential thermal expansion and contraction between the shafts and housing.

International Classification:

F16C 33/76

US Classification:

384481, 384477

Abstract:

A bearing assembly (A-H) enables one member () to rotate relative to another member () about an axis (X). It includes a bearing () having an inner race () on one of the members, an outer race () in the other member, and rolling elements () between raceways on the two races. A seal () excludes contaminants from the interior of the bearing, and it includes a wear ring () carried by an extension () on the outer race beyond the raceway of that race, a contacting wear ring () carried by the member on which the inner race is located or else by a can () that is fitted to the inner race. The seal also includes backing elements () for supporting the wear rings on that which carries them, and in most instances the backing elements exert a biasing force on the wear rings to maintain them in contact, so that they establish a dynamic fluid barrier. The backing elements may include O-rings (), polymer connecting segments () or springs () and a membrane ().

The Timken Company - Canton OH

International Classification:

F16C 19/49

US Classification:

384494, 384453, 384563

Abstract:

A locating bearing assembly () is provided that optimizes load distribution between bearing rows and for all rolling elements within the rows in either positive or negative torque conditions, by combining a single row tapered roller bearing with an angular contact ball bearing. The outer race () for the ball bearing is preloaded by a spring element () to prevent the balls () from floating freely between the ball bearing's inner and outer raceways (). This will insure that the balls () are always sufficiently loaded to roll along a single axis which is off set from the radial direction. The use of the single row tapered bearing and the preloaded angular contact ball bearing provides for a locating bearing assembly (“LBA”) in which the ball bearing supports only reversing axial loads. All radial loads are borne by the tapered roller bearing and transmitted to the bearing assembly housing ().
