Introduces a common model and type roller bearing structure design

Introduces a common model of roller bearing and roller bearing has two type structure design, one is the aircraft flight control part of the use of; This kind of roller bearing is a bearing inner race and the external cage between seat will roller is fixed, can automatically self-aligning bearing. Divided into single row roller bearing self-aligning roller bearing and double LieDiao heart. Compared with the ordinary spherical bearings, rod end bearing, its characteristic is that the starting torque is low. Roller bearing is one of the important parts for aircraft flight control system. In addition a part is the engine of the plane, and this kind of roller bearing is mainly used for aircraft engine parts, its characteristic is contact part of the bearing outer ring and inner ring assembly has a cylindrical roller. The inside of the roller bearing is a cylindrical roller, is line contact, so the friction speed without the ball high, but because of the large contact area also can bear big load. Rolling body is cylindrical roller bearing, including cylindrical roller bearings, thrust cylindrical roller bearings. The internal structure of cylindrical roller bearing by roller are arranged in parallel, with intervals between roller device or the isolation piece, can prevent roller friction between tilt or roller, effectively prevent the rotation torque increases. Roller bearing type: R - 410 R - 412 R - 515 R - 615 R - 620 620 w52 R - 720 R - 725R- 825 R - 830 R - 930 R - 930年y52 R - 1030 R - 1140 R - 1240 R - 1340 r - 1350 R - 1450 R - 1560 R - 1640 R - 1650 R - 1760 x2 R - 1950 R - 1960 r - 1970 R - 1980 R - 2270 R - 2280 R - 2210年x3 R - 515ZZ R- 615ZZ
