Object of the present invention realizes in the following manner: a kind of built up gear case, comprise gear-box, in gear-box, be provided with power shaft, intermediate gear shaft and output shaft, between them, pass through pitch wheel transferring power, it is characterized in that: it is connected is a little public axle tie point and casing flexible connection point, and concrete structure is as follows:
A) gear-box comprises prime gear-box and rear class gear-box, they have separately independently casing, and a public axle is the output shaft of prime gear-box, are again the power shafts of rear class gear-box, after prime gear-box and rear class gear-box are arranged side by side, by public axle, front and back gear-box is connected;
B) the casing front end of prime gear-box is provided with a pair of connecting plate, the casing front end of rear class gear-box is provided with base for supporting, and base for supporting is provided with support, is also provided with a pair of connecting plate on support, two pairs of connecting plates are mutually corresponding, on two pairs of connecting plates, are equipped with the pin-and-hole of being furnished with bearing pin; Two oscillating bearings connect by connecting rod, and by bearing pin and pin-and-hole, they are positioned respectively in corresponding a pair of connecting plate, form and are flexibly connected point.
In the present invention: two oscillating bearings are connected and referred to by connecting rod, are provided with the hole corresponding with oscillating bearing at the two ends of connecting rod, in the hole that two oscillating bearings are placed in one respectively; The casing front end of rear class gear-box is provided with base for supporting and establishes finger: base for supporting is fixedly connected with the casing front end of rear class gear-box by bolt.
In the present invention: the output gear wheel periphery of described rear class gear-box at least connects by two equally distributed public axle prime gear-boxes identical with technical parameter, and the casing of rear class gear-box is formed and is flexibly connected a little by oscillating bearing, connecting rod and bearing pin by described base for supporting, support, connecting plate again with the casing of prime gear-box.
The invention has the advantages that: be mutually located by connecting because the prime gear-box in built up gear case and rear class gear-box are flexibly connected point by public axle tie point and casing, connected mode for the structure of traditional casing supported at three point is compared, its machining accuracy and installation code are relatively low, more convenient to operate, because the casing front end of prime gear-box is provided with a pair of connecting plate, the casing front end of rear class gear-box is provided with base for supporting, base for supporting is provided with support, on support, be also provided with a pair of connecting plate, two pairs of connecting plates are mutually corresponding, on two pairs of connecting plates, be equipped with the pin-and-hole of being furnished with bearing pin, two oscillating bearings connect by connecting rod, and by bearing pin and pin-and-hole, they are positioned respectively in corresponding a pair of connecting plate, form the flexible connection point of triangle statically determinate structure, and base for supporting is fixedly connected with the casing front end of rear class gear-box, its structure is very compact, be convenient to installing/dismounting, two oscillating bearings that are flexibly connected in point form two universal joints up and down at connecting rod, improve impact resistance and the service life of whole gear-box.
