PCT No. PCT/GB81/00188 Sec. 371 Date May 6, 1982 Sec. 102(e) Date May 6, 1982 PCT Filed Sep. 14, 1981 PCT Pub. No. WO82/01050 PCT Pub. Date Apr. 1, 1982.The drive gearbox comprises an in-line primary box, a right-angled primary box and a nose module which can be coupled to one or both primary boxes. Each primary box has an open-ended interface which exposes gearing and the nose module has two open interfaces which expose gearing when the primary boxes are coupled to the nose modules, the gearings mesh with the gearing. If only one primary box is coupled to the nose module, a cover (not shown) is placed over the open interface. A gearbox formed of nose module and one or both primary boxes are advantageous in several ways, such as adaptability, power capacity, shape and size and design.
