938,935. Toothed gearing. MAAG GEAR WHEEL & MACHINE CO. Ltd. June 13, 1960 [July 9, 1959], No. 20706/60. Class 80 (1). In a toothed gear having parallel driving and driven shafts 18, 15 carrying pinions 1, 14, interconnected by pinions 10-13 on two intermediate shafts 8, 9, the driving shaft 18 is free to move transversely in a plane containing the axes of driving and driven shafts so as to ensure that, for a predetermined load, the load is transmitted equally through the two intermediate shafts. The driving shaft 18 is supported on either side of its pinion 1 by bearings 2, Fig. 1, or 23, Fig. 4, which are either pivoted at 5, Fig. 1, or connected through webs 25 and brackets 24, to one part 7 of a three-part casing 7, 16, 27. The webs 25 bend to permit transverse movement of the shaft 18 and the bearings 2 or 23 are interconnected by struts 4. The vertical component of toothed pressure, for the predetermined load, is balanced by a spring 31 acting on the bearings. The transverse movement of the shaft 18 and its bearing 23 is limited by a stud 19 and a cup 29 which houses the spring 31. Specification 938,934 is referred to. |
