Title: Connecting rod and process for the manufacture thereof
Inventor: AICHELE WILFRIED DIPL CHEM DR
IPC: B29C70/34
Filed: 1983-05-10
Abstract: A connecting rod and a process for the manufacture thereof are proposed, the connecting rod, with the exception of the bearing bushes, consisting of fibre-reinforced synthetic resin and being very simple in its construction and therefore economical in its manufacture. The core of this connecting rod is one-part and has a plurality of fibre layers, the fibres extending alternately in the direction of the longitudinal axis of the connecting rod and at an angle of +10 DEG  to +30 DEG  and -10 DEG  to -30 DEG . A connecting rod of this type is preferably manufactured in such a manner that the core is manufactured by machining from a laminate sheet with the corresponding fibre orientations, coated with a suitable adhesive at the cut sides, bonded to the bearing bushes and inserted in a winding mould, that resin-impregnated glass or carbon fibre rovings are wound around bushes and core, and that resin and adhesive are precured and postcured at relatively high temperature after demoulding of the connecting rod. In the case of low pressure loading of the connecting rod, a core manufactured with the already finished contour and made of fibre-reinforced moulding compound can be used instead of the core with strictly oriented fibres. <IMAGE>

Title: Plastic ring support with sealing lip for the sealing of rolling bearings
Inventor: FEY JOSEF
IPC: F16C33/76
Filed: 1983-10-31
Abstract: For the combined sealing of rolling bearings, in particular tapered-roller bearings, plastic ring supports 1 for the fitting of sealing multipiece rings 2 are provided with laterally adjoining sealing lips which come into contact with the end faces 3, 4 of the rolling bearing rings. Since the spacings of the end faces 3, 4 of the tapered-roller bearings 5 vary greatly from make to make for the same sizes of bearing, until now sealing lips 3 of different lengths had to be manufactured and kept in stock for each make for the same bearing sizes. The axially highly flexible type of construction according to the invention of the proposed convex sealing lips 6 has the effect of compensating for relatively great spacing tolerances, so that standard plastic ring supports with sealing lip can be used for the same bearing sizes. <IMAGE>
