Abstract
The utility model relates to a lubricating device of a speed reducer, belonging to the technical field of lubricating devices of speed reducers and aiming at solving the problem of providing the lubricating device of the speed reducer, which has the advantages of bidirectional rotation, convenience for maintenance after fault and safe transportation process. The lubricating device of the speed reducer is characterized in that a pump connecting plate is fixedly arranged on a box body of the speed reducer; a bidirectional gear pump is fixedly arranged on the pump connecting plate, and a bidirectional reversible cycloid gear pump is positioned in a bearing cover; the bidirectional gear pump penetrates through the pump connecting plate through a transmission shaft to be connected with a driven shaft of the speed reducer; the oil inlet of the bidirectional reversible cycloid gear pump is connected with one end of an oil suction pipe, and the oil outlet is connected with one end of an oil outlet pipe; the other end of the oil suction pipe extends from the bottom of the box body of the speed reducer into a lubricating oil pool inside a shell, and the other end of the oil outlet pipe extends into a forced lubricating part inside the box body of the speed reducer; and the oil suction pipe and the oil outlet pipe are both arranged outside the speed reducer. The lubricating device is mainly used for the lubrication of the speed reducer.
Description
Technical field
The lubricating fitting of a kind of retarder of the utility model belongs to the lubricating fitting technical field of retarder.
Background technique
The oil pump that uses during present most of retarder pressure lubrication is not reversible, and after retarder input rotation direction changed, inlet port and oil outlet were perhaps changed in installation that will the conversion oil pump, and operation is not very convenient.And lubricating oil path is to deliver to the unappeasable place of splash lubrication to oil at the inner copper pipe etc. of adopting of retarder; The maintenance after lubricating oil path breaks down of this structure is inconvenient especially; And the service cycle meeting is long, can cause very big influence to production, and oil pump is fixed to directly on the end cap of retarder; In transportation process, also be easy to damage, cause unnecessary loss.
The model utility content
The utility model overcomes the deficiency that existing technology exists, technical problem to be solved provide a kind ofly can two-wayly rotate, the lubricating fitting of the retarder of easy to maintenance after the fault, transportation process safety.
For solving the problems of the technologies described above; The technological scheme that the utility model adopted is: a kind of lubricating fitting of retarder; Comprise pump joining plate, double-direction gearpump, fuel sucking pipe and oil outlet tube; Said pump joining plate is fixedly mounted on the reduction case, and double-direction gearpump is fixedly mounted on the pump joining plate and the bidirectional reversible cycloid gear pump is positioned at bearing cap inside, and double-direction gearpump passes the pump joining plate through transmission shaft and is connected with the retarder driven shaft; The filler opening of said bidirectional reversible cycloid gear pump connects with an end of fuel sucking pipe; Oil outlet connects with an end of oil outlet tube, and the other end of fuel sucking pipe stretches into the lubricating oil bath of enclosure interior from the reduction case bottom, and the other end of oil outlet tube stretches into the position of pressure lubrication in the reduction case; Said fuel sucking pipe and oil outlet tube all are arranged on the retarder outside.
The utility model is compared with existing technology has following beneficial effect.
1, through using the bidirectional reversible cycloid gear pump to substitute the irreversible oil pump of existing rotation direction, make retarder input rotation direction change after more scavenge oil pump installation or change inlet port and oil outlet, easy to use.
2, inner through double-direction gearpump being installed in retarder bearing lid, make retarder in transportation process, double-direction gearpump is difficult for being damaged.
3, through being set to the lubricating pipe of retarder the outside of retarder, can keep in repair easily after making lubricating pipe break down, reduce influence to producing.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the horizontal cross of the utility model.
Among the figure, 1 is reduction case, and 2 is the retarder driving shaft, and 3 is oil outlet tube, and 4 is the retarder driven shaft, and 5 is the pump joining plate, and 6 is double-direction gearpump, and 7 is bidirectional reversible cycloidal gear pump drive shaft, and 8 is bearing cap, and 9 is fuel sucking pipe.
Embodiment
Like Fig. 1, shown in Figure 2; A kind of lubricating fitting of retarder; Comprise pump joining plate 5, double-direction gearpump 6, fuel sucking pipe 9 and oil outlet tube 3; Said pump joining plate 5 is fixedly mounted on the reduction case 1, and double-direction gearpump 6 is fixedly mounted on the pump joining plate 5 and bidirectional reversible cycloid gear pump 6 is positioned at bearing cap 8 inside, and double-direction gearpump passes pump joining plate 5 through transmission shaft 7 and is connected with retarder driven shaft 4; The filler opening of said bidirectional reversible cycloid gear pump 6 connects with an end of fuel sucking pipe 9; Oil outlet connects with an end of oil outlet tube 3, and the other end of fuel sucking pipe 9 stretches into the lubricating oil bath of enclosure interior from reduction case 1 bottom, and the other end of oil outlet tube 3 stretches into the position of pressure lubrication in the reduction case 1; Said fuel sucking pipe 9 all is arranged on the retarder outside with oil outlet tube 3.
Bidirectional reversible cycloid gear pump 6 in the utility model is an existing technology.
Bidirectional reversible cycloid gear pump 6 in the utility model is ultrathin double-direction gearpump 6.
The working procedure of the utility model is: after outside output shaft drives retarder driving shaft 2; Retarder driving shaft 2 drives retarder driven shaft 4 and rotates; Retarder driven shaft 4 drives double-direction gearpump transmission shaft 7 through coupling again and rotates; And then drive double-direction gearpump 6 and start working, fuel sucking pipe 9 is from the inner lubricating oil bath oil suction of reduction case 1, and oil outlet tube 3 is delivered to the place that the inner splash lubrication of retarder can not arrive with oil and is lubricated then; Lubricated back oil flows back to the lubricating oil bath of reduction case 1 inside again, so recycles.
