Description

Suspension speed reducer

Technical Field

The utility model relates to a speed reducer field, concretely relates to hang speed reducer.

Background

The application occasions of speed reduction are more, the positions of connecting structures for installing the speed reducers in transmission systems of various machines are different, most of the positions of the corresponding input devices and output devices are different, and therefore the speed reducers corresponding to the structures of the speed reducers can be used in different machines in the practical process. Traditional speed reducer adopts the top lug to articulate or the unilateral draw-connection of side footing when the installation is hung to needs, decides the lug and articulates the structure and be unfavorable for stabilizing input and output under high-speed drive's service environment, easily takes place the rigidity and damages, and suspension type speed reducer generally is slenderness type moreover, and lubricating oil is all in the bottom, and the gear at top is difficult to lubricate.

Disclosure of Invention

For the suspension and the lubrication problem of suspension type speed reducer among the solution prior art, the utility model aims to provide a structure is firm, can self-lubricating suspension type speed reducer.

In order to achieve the above purpose, the utility model adopts the technical proposal that:

a suspension speed reducer comprises a speed reduction box, an input shaft and an output shaft, wherein the speed reduction box comprises a left box body and a right box body, the input shaft is connected with the output shaft through multi-stage gear transmission, lifting lugs are welded at the tops of the left box body and the right box body respectively, and supporting legs are arranged at the bottoms of the left box body and the right box body respectively; the oil pump extracts lubricating oil from the bottom of the reduction gearbox and sends the lubricating oil to the top of the reduction gearbox through an oil pipe, the output end of the oil pipe is connected with a uniform distribution pipe, the top in the reduction gearbox is installed on the uniform distribution pipe, the oil pipe is connected with the middle of the uniform distribution pipe, the uniform distribution pipe comprises a horizontal pipe and bending pipes symmetrically distributed at two ends, lubricating holes are uniformly distributed on the uniform distribution pipe, and the end parts of the bending pipes at the two ends are open.

Furthermore, the input shaft, the three-stage intermediate shaft and the output shaft are arranged in the reduction gearbox from top to bottom.

Furthermore, the output shaft is a hollow shaft, and a locking device is installed at the shaft end of the output shaft.

Still further, locking device includes lock sleeve and two locking dishes, and the bolted connection is locked between two locking dishes.

By adopting the technical scheme, the utility model has the advantages that the gravity of the box body is shared by the double lifting lugs at the top part and the double supporting feet at the bottom part of the reduction box, the service life of the box body is prolonged, and the damage is prevented; the output shaft is utilized to drive the oil pump to extract lubricating oil from the bottom and then the lubricating oil is uniformly distributed and sprayed through the distribution pipe, so that gears in the box are lubricated, and the purpose of self-lubrication is achieved. The mechanism of the technical scheme is stable and has good lubricating effect.

In the figure: the oil pump comprises an input shaft 1, a three-level intermediate shaft 2, an output shaft 3, a left box body 4, a right box body 5, lifting lugs 6, supporting legs 7, an oil pump 8, an oil pipe 9, an evenly distributed pipe 10, a locking sleeve 11 and two locking discs 12.

Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings:

as shown in the figure, the suspension speed reducer comprises a speed reduction box, an input shaft 1 and three-level intermediate shafts 2 and an output shaft 3, wherein the speed reduction box comprises a left box body 4 and a right box body 5 which are fixedly connected through a plurality of bolts in a use state. Lifting lugs 6 are welded at the tops of the left box body and the right box body respectively, and supporting legs 7 are arranged at the bottoms of the left box body and the right box body respectively; the input shaft 1 is in meshing transmission to the output shaft 3 through the three-level intermediate shaft gear pair 2, one end of the input shaft 1 is connected with a motor through a coupler, the other end of the input shaft 1 is connected with an oil pump 8, the oil pump 8 is installed on the outer side of the reduction gearbox, and a rotating shaft of the oil pump 8 is connected with the input shaft through a pin or a key and is driven by the input shaft. The oil pump 8 extracts lubricating oil from the bottom of the reduction box and sends the lubricating oil to the top of the reduction box through the oil pipe 9, the output end of the oil pipe is connected with the uniform distribution pipe 10, the uniform distribution pipe 10 is installed at the top in the reduction box, the middle part of the uniform distribution pipe 10 is connected with the oil pipe 9, the uniform distribution pipe comprises a horizontal pipe and bending pipes symmetrically distributed at two ends, lubricating holes are uniformly distributed on the uniform distribution pipe, the end parts of the bending pipes at two ends are open, the lubricating oil is sent into the uniform distribution pipe 10 after being extracted from the bottom of the reduction box, the lubricating oil is uniformly sprayed downwards through the uniform distribution pipe 10, and each.

The output shaft 3 is a hollow shaft, the hollow shaft is connected with a load, and a shaft for feeding the load is inserted into the central shaft. The locking device is installed to the axle head of quill shaft, and locking device includes lock sleeve 11 and two locking discs 12, and lock sleeve 11 overlaps the axle head at the quill shaft, and the external diameter of the outer wall of lock sleeve 11 is dwindled to both sides along the axis by the middle part gradually, and two locking discs 12 overlap in lock sleeve 11 from the both sides of lock sleeve 11, and the tight extrusion lock sleeve 11 of bolt tensioning extrusion by many equipartitions between two locking discs 12, and lock sleeve 11 is to the radial application of force of quill shaft, and the quill shaft that is rather than the load fastening connection.
