The rotary disc feeding device is simple in structure and can effectively meet the high-sealing use requirements of disc feeding support and rotary output.
Description
Technical Field
The utility model relates to a speed reducer, a special speed reducer of disc feed specifically says so.
Background
The disc feeding is commonly adopted in a general mill and a dryer, the reduction box is mostly adopted to support and drive the rotary feeding, and due to the special conditions of powder, high temperature and the like in the use occasions, when the output is output on the output shaft of the reduction box, the output shaft is connected with the support cover in a penetrating way and easily leaks into a sealing part, so that the output shaft is damaged, and the problems of stable use, safety, service life and the like of the reduction box are caused.
Disclosure of Invention
The utility model provides a simple structure can effectively adapt to the special speed reducer of disc feed of the high leakproofness that the disc feed supported, rotatory output.
The utility model adopts the technical proposal that: the utility model provides a disc feed speed reducer, includes box, input shaft, gear drive group, output shaft, and the input shaft cross-under box is through gear drive group transmission output shaft, its characterized in that: the output shaft is supported upwards through the bearing and penetrates out of the box body through the sealing cover, two oil seals which are arranged in a back-to-back mode are arranged between the output shaft and the sealing cover, a circular bead for mounting the disc support is arranged on the outer side of the sealing cover, and a radial sealing ring and an axial sealing ring are arranged on the circumference and the end face of the circular bead in a groove mode respectively.
Further, the oil seal arranged in the forward direction in the two oil seals faces inwards.
Furthermore, the input shaft is an input bevel gear shaft which penetrates through one side of the box body, the gear transmission set comprises a plurality of stages of cylindrical gear transmission sets which are arranged in parallel and sequentially transmit, and the input bevel gear shaft is meshed with a bevel gear on the one-stage cylindrical gear transmission set.
Furthermore, the lower end of a first-stage transmission shaft of the first-stage cylindrical gear transmission set penetrates out of the external bidirectional lubricating flange pump of the box body downwards, one end of the bidirectional lubricating flange pump is connected with the inner cavity at the lower part of the box body, and the other end of the bidirectional lubricating flange pump is connected with an oil valve at the upper part of the box body and then is connected with the inner cavity at the upper part of the box body in a shunting manner.
Furthermore, one end of the bidirectional lubricating flange pump is connected with an inner cavity at the lower part of the box body through an oil filter.
Further, the input bevel gear shaft and the bevel gear are in hard tooth surface meshing.
The utility model has the advantages that: the oil discharged from the lower part of the inner cavity of the speed reducer box body is filtered by an oil filter and then pumped to each bearing position on the upper part of the box body by a bidirectional lubricating flange to be soaked in the oil for lubrication; the sealing cover penetrating through the output shaft adopts the oil seal arrangement with two opposite sides, so that lubricating oil can be prevented from seeping and external oil can be prevented from seeping, radial and axial sealing rings on the shoulder of the sealing cover are combined with radial and axial sealing connection of the disc support, external material dust can be effectively prevented from entering the speed reducer, and the high sealing performance of disc feeding support and rotary output is realized.
