Patent GB-926959-A (GB)
Abstract: 926,959. Bearings. MINNEAPOLIS-HONEYWELL REGULATOR CO. May 26, 1959, No. 17980/59. Class 12 (1). [Also in Group XX] In a gyroscope having a spin rotor mounted to rotate on bearings carried by support means on a gimbal, the bearings have an optimum contact angle and may be pre-loaded over a range without affecting the relationship between axial and radial deflections and so prevent an increase in gyro drift torque. The gimbal assembly, Fig. 2, comprises cup-shaped portions 16<SP>1</SP>, 16<SP>11</SP>, the latter having extensions 35, 36 carrying a stator shaft 37 of a motor 25. The shaft 37 has inner races 42, 46 of bearings 40, 44 mounted thereon and each bearing is pre-loaded by a pressure washer 47 which engages the inner race and which is forced by a nut 48 threadably engaging the shaft 37. Outer races 41, 45 are constrained against axial movement by end-bell members 33, 34. Each bearing 40, 44, one of which is shown in Fig. 3, has the inner race 42 tapered at 42<SP>1</SP> and, at the point where the inner race contacts each ball, the surface 42<SP>1</SP> is radiused. The inner surface of the outer race 41 has a curved recess 41<SP>1</SP> to receive each ball. The optimum contact angle # is 20 degrees. The relationship between axial and radial deflections may be adjusted by varying the effective length of the shaft 37, Fig. 7, one end 60 of which has left-hand threads and the other end 61 has right-hand threads engaged by nuts 56, 57 respectively which are threadably supported in inserts 52, 53 screwed into a gimbal case 16. By rotating the nuts on the shaft 37 which is held stationary, the nuts move inwardly or outwardly to decrease or increase the effective length of the shaft 37 and so change the compliance of the shaft to acceleration in the I.A. direction Fig. 1, without affecting the compliance of the gimbal assembly to acceleration in the S.R.A. direction. In a further method of varying the relationship between axial and radial deflections, the inserts 62, 63, Fig. 9, are externally threaded on to the gimbal case 16 and have inwardly-projecting keys which engage in keyways 68, 69 in the plain ends of the shaft 37 which are received in bores 66, 67 of the inserts 62, 63. The shaft 37 has integral collars 70, 71 which are cut-away to provide a non- circular cross-section, Fig. 10. This permits the compliance of the gimbal assembly to acceleration in the I.A. direction to be made equal to the compliance of the gimbal assembly to acceleration in the S.R.A. direction for, by rotating the shaft 37 to a position in which the section 37<SP>1</SP> has its longest direction parallel to the I.A. direction, the least compliance of the shaft to acceleration in the I.A. direction is obtained, the maximum compliance occurring when the shaft is adjusted through 90 degrees from this setting. As an alternative, the cutaway portions are replaced by a diametral bore 80, Figs. 11 and 12. The rotation of the shaft 37 has no effect on the compliance of the gimbal assembly to acceleration in the S.R.A. direction.
