Description

Gear box structure for mining machinery convenient to dismantle Technical Field The utility model relates to the technical field of gearboxes, in particular to a gearbox structure for mining machinery, which is convenient to detach. Background The gearbox is an important part widely applied in mechanical transmission, the gearbox is widely applied in a wind generating set, the gearbox bears acting force from a wind wheel and counter force generated during gear transmission, the gearbox must have enough rigidity to bear the action of force and moment, deformation is prevented, transmission quality is guaranteed, the existing gearbox is generally formed by fixedly connecting a box cover with a gearbox body through bolts, and when the gear in the gearbox body is maintained, the box cover is removed only after the bolts are removed through special tools, so that time is wasted, and great trouble is brought to workers. The utility model discloses a gear box convenient to maintain, and discloses a gear box convenient to maintain, belonging to the technical field of gear boxes. The utility model provides a gear box convenient to maintenance, includes the gear box body, is equipped with the case lid above the gear box body, and gear box body and case lid surface have excavated a plurality of rectangle through-holes down and go up rectangle through-hole respectively, and rectangle through-hole down is corresponding with last rectangle through-hole position, and case lid surface fixedly connected with is many pairs of locating pieces, can be convenient for take off the case lid from the gear box body, and then maintains the inside gear of gear box body, and the operation is comparatively convenient, saves operating time. However, when the gearbox is lifted and disassembled at the narrow position of the mine, the lifting ring cannot be adjusted at will, so that the crane cannot effectively play a role in a narrow space, and when the gearbox is lifted, the lifting gravity center and the gravity center of the gearbox cannot be overlapped, the gearbox can be inclined, and the gearbox cannot be lifted and maintained normally.
