Patent GB-191080-A (GB)
IPC: G01M1/04
Filed: 1922-12-30
Abstract: 191,080. Krupp Akt.-Ges., F. Jan. 2, 1922, [Convention date]. Testing balance of rotary apparatus.-Comprises a construction of knife-edge apparatus particularly adapted for testing machine parts in which the body is mounted on a shaft extending on both sides thereof. Each extension is adapted to be received into a bearing in part B formed with a knife-edge b<1> which may be adjusted at right-angles to the knife-edge and which rests on a seat c<1> in a support C. The bearing is fitted with rollers E and a cap b<3> by which and the studs b<4> the part B may be firmly clamped to the shaft. The part B is fitted with fixed abutments b<5> which are adapted to be engaged by set screws G on the brackets c<2> and with spring- pressed studs H adapted to engage abutments c<3> on the brackets c<2>. Two-part graduated rings F are fitted to the shaft outside the parts B. In use, the body A mounted on its shaft A' is suspended by a crane over two supports C as shown. The parts B are then engaged by their bearings and caps with the shaft A and turned so that the spirit-levels L with their air-bubbles balance. The parts B are then firmly clamped to the shaft by the studs b<4>. The graduated rings F are also secured to the shaft in any angular position. The body A and parts B are then lowered so that the knife-edges b<1> engage their seats. The set screws G are moved to prop up the whole so that the levels L continue to balance. The springs J, which previously have been adjusted to equal tension, are now further adjusted so that the pointers h<2> are against the same graduation on each scale b<7>, thus all exercising equal forces on the studs H. If now, the screws G are withdrawn and the levels remain unaltered, the body is in static balance. If not, the screws G are again moved back until the levels L balance. The caps b<3> are then loosened and the body A rocked through a small angle. The balance is tested as before, and the rocking repeated until the levels balance, when the screws G are withdrawn. The reading of the graduated ring against the mark b<2> is then noted, and the caps b<3> are loosened and the shaft moved through exactly ninety degrees. The compression of the springs J necessary to restore the balance of the levels is a measure of the out of balance weight on the heavier side of the body. Instead of compressing the springs on the heavier side, suitable weights M may be placed on the faces b<8> of the opposite side,. In a modification, the springs and studs h<2> are mounted on the part c<2> and act through levers on studs on the part B. The Specification as open to inspection under Sect. 91 (3) (a) states that the apparatus may be used for testing dynamic balance after static balance has been secured as above by loosening the caps b<3> and rotating the body A at a sufficiently high speed. The couples due to dynamic unbalance may then be balanced by arranging equalizing weights at both sides of the axis. This subject-matter does not appear in the Specification as accepted.
