Abstract

1400351 Ground-engaging tooth assembly CATERPILLAR TRACTOR CO 21 Sept 1973 [29 Sept 1972] 44387/73 Heading E1F A replaceable ground-engaging tip 14 for mounting on an adapter 10 on the cutting edge of an excavating bucket has a wedge shaped body comprising the wear part of the tip and rearwardly extending straps 18, 20 at the top and bottom of the body. The straps diverge from the body to form an open-sided generally U-shaped opening 16 for the reception of the nose 17 of the adapter. Each strap has a key 22, 24, which extends laterally of the strap near the rear end of the strap. The keys project normal to the straps and engage respective keyways 26, 28 in the adapter. All loads on the tip are transferred to the adapter through the keys and keyways. The loads on the tip are transmitted through the straps in tension compression rather than in bending so that the straps can be made of quite thin sections. The tip is self locking on the adapter because of the friction produced between the keys and keyways. The keys may face inwards or outwards and a locking means 30 may also be provided between the tip and an associated adapter to prevent side ways movement of the tip along the adapter.
