fig. 2 is a schematic structural view of the reduction gearbox of the retractable door machine according to an embodiment of the present invention at another viewing angle.

Detailed Description

The present invention will be described in further detail with reference to the following description of the drawings.

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1, the reduction gearbox of the telescopic portal crane comprises a mounting base 1, a reduction gearbox body 2 connected with the mounting base 1, and a motor box body 3 connected with the reduction gearbox body 2.

The mounting base 1 includes base body 11 and the installation department 12 of locating the 11 four corners of base body, and in this embodiment, base body 11 is the rectangle form, and installation department 12 and base body 11 integrated into one piece have seted up installation screw 121 on the installation department 12, and base body 11 is last to have reduction box 2 through welding mode or bolt mode rigid coupling.

The reduction box body 2 comprises a hollow body part 21, a movable end cover 22 and a fixed end cover 23, wherein the movable end cover 22 and the fixed end cover 23 are arranged at two ends of the body part 21, the movable end cover 22 is fixed on the body part 21 through bolts, the fixed end cover 23 and the body part 21 are integrally formed, a bearing seat 24 is arranged on the fixed end cover 23, and a rotating shaft 4 is inserted on the bearing seat 24.

The fixed end cover 23 is fixedly connected with the body part 21 through welding or integral forming, the fixed end cover 23 comprises a circular cover body 231, the middle part of the cover body 231 is fixedly connected with a bearing seat 24 through welding, the middle part of the bearing seat 24 is fixedly connected with a rotating shaft seat 232 through welding, and the cover body 231, the bearing seat 24 and the rotating shaft seat 232 are coaxially arranged. This design makes the rotation of the shaft 4 more accurate and the installation of the shaft easier.

The pivot seat 232 is the hollow sleeve pipe, and sleeve pipe one end rigid coupling has seted up grooved portion 2321 in bearing frame 24, the other end along the sleeve pipe port, and grooved portion 2321 can be very easy sees the operation process of inside pivot 4, when pivot 4 lacks the lubrication, can add emollient so that pivot 4 rotates the effect better through grooved portion 2321.
