Abstract
The utility model relates to a single-purpose speed reducer for the screw conveyer. The structure of the single-purpose speed reducer for the screw conveyer is that the flanges of a front box body are installed fixedly on the end covers of the flanges of a standard motor by bolts and an elastic ring, and an input gear shaft is connected with the output shaft of the motor by a flat key. The input gear shaft is engaged with a driven gear which is installed between the two bearings of an output gear shaft. The shaft platform of an output shaft which is extended out of the external part of a rear box body is provided with a felt seal that is fixed on the external end part of the rear box body by screws and glands so as to prevent the leakage of the materials in the conveyor. The output shaft is connected directly with the screw conveyer by splines, and the coupling is cancelled; simultaneously one supporting point of the screw conveyer is also formed, and the tail part on the other end of the output shaft is provided with a thrust bearing capable of overcoming the external axial force. The utility model, which has the features of simple and compact structure, small volume, convenient match, easy examination and repair, and convenient installation, can reduce the product cost and improve the economic performance and the market competition ability.
Description
Technical field
The utility model belongs to speed reducer, particularly relates to a kind of screw conveyor special reduction gear.
Background technique
At present, speed reducer on the domestic known screw conveyor is used horizontal gear reduction unit or horizontal cycloid speed reducer usually, and the speed reducer of these two kinds of routines is connected with screw conveyor by coupling again, the screw conveyor of original structure has a style of one's own, so should there be two fulcrums its conveyor inside; Its conventional speed reducer volume is bigger, and structure is also complicated, and the drive motor that its two kinds of speed reducers are joined is definite-purpose motor, so the versatility of its auxiliary motor is poor, is not easy to maintenance and replacing.
Summary of the invention
The utility model provides a kind of screw conveyor special reduction gear for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of screw conveyor special reduction gear, it is made up of preceding casing, rear box, input gear shaft, bearing, driven gear, back-up ring, oil deflector, felt sealing, gland, output shaft, motor, spline, bolt, packing ring and fastening piece, it is characterized in that: the input gear shaft connects the shaft of motor by flat key, input gear shaft engagement driven gear, driven gear are packed between two bearings of the other end of output shaft; Stretch out at output shaft the felt sealing is installed on the pillow block of rear box outside, the felt sealing is fixed on the outer end of rear box by screw, gland, and output shaft is by spline and screw conveyor direct connection, and the afterbody of the output shaft the other end is equipped with a thrust-bearing.
Advantage and the good effect that the utlity model has are: the motor that this screw conveyor special reduction gear necessary electromotor is used the general standard type instead drags, so change accessory and keep in repair very convenient.The output shaft of this special reduction gear is by spline and screw conveyor direct connection, cancelled the bind mode of using coupling in the known technology, simultaneously, the output shaft of this speed reducer constitutes fulcrum of screw conveyor, make two fulcrums of the screw conveyor in the known technology become a fulcrum, therefore, this screw conveyor special reduction gear is compared with two kinds of conventional speed reducers in the known technology, have simple and compact for structure, volume is less, change that accessory is convenient, maintenance easily; It and screw conveyor direct connection, easy for installation, easily simple.It is supporting to use standard motor simultaneously instead, and direct connection is installed, and has cancelled coupling piece, can reduce product cost, increases economic efficiency and the market competitiveness.Adopted the felt sealing at the output axle head, can prevent that the material from leakage in the conveyor from coming out, also the tail portion at output shaft is equipped with a thrust-bearing, can overcome external axial force.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, the flange end cover bolt of motor 11, spring washer and preceding casing 1 are connected, the shaft of motor 11 connects by flat key and input gear shaft 3, input gear shaft 3 is meshed with driven gear 5, driven gear 5 is packed between two bearings of the other end of output shaft 10, the inner ring of rear end bearing is fixed with back-up ring 6 outward, oil deflector 7 is equipped with in the outside of preceding step bearing, rear box 2 is installed on the preceding casing 1 by bolt, stretch out at output shaft 10 felt sealing 8 is installed on the pillow block of rear box 2 outsides, screw is passed through in felt sealing 8, gland 9 is fixed on the outer end of rear box 2; Output shaft 10 is by spline and screw conveyor direct connection, and a fulcrum of formation screw conveyor, and the afterbody of output shaft 10 the other ends is equipped with a thrust-bearing 4, can overcome external axial force.
