Abstract
The utility model discloses a drilling machine winch barrel bearing device convenient for injecting lubricating oil. The device comprises a barrel, a bearing seat and a hollow sleeve bearing box, wherein the hollow sleeve bearing box is fixed on the inner side of the bearing seat; the periphery of a shaft sleeve and a bearing cap a are sealed through a bearing cap sealing sleeve; a flow channel is arranged between the shaft sleeve and the bearing cap sealing sleeve; the flow channel is communicated with an oil channel of the bearing seat; a bearing cap b for fixing the bearing seat is arranged on the outer side of the bearing seat; a channel is arranged inside the bearing cap b; the channel is communicated with the oil channel and an oil pipe; the oil pipe is connected to an oil inlet. When the barrel rotates, the lubricating oil enters the channel of the bearing cap b from the oil pipe, and as the bearing cap b is fixed and cannot rotate with the barrel, the lubricating oil enters the oil channel along the channel and enters the flow channel from the oil channel, cannot be splashed because the flow channel is sealed during the process, and can lubricate the barrel and bearings in the hollow sleeve bearing box.
Description
Technical field
The utility model relates to mechanical equipment and manufactures field, is specifically related to a kind of Drum Shaft of Rig Drawworks bearing apparatus of being convenient to inject lubricating oil.
Background technology
Winch, as the visual plant in hoisting system of rig, can be realized derrick lifting, drill string handling etc. by drum rotating.After bearing use a period of time in the cover bearing box of winch drum shaft overhead, need again to beat butter lubricated.Empty set bearing box belongs to tumbler, alemite position on empty set bearing box often changes thereupon, and fixes for the window that adds butter on guard shield, and while adding butter, the frequent position that must first alemite be turned to window is played butter again, inconvenient operation, has reduced work efficiency.
In order to solve above-mentioned deficiency of the prior art, the utility model proposes a kind of new solution.
Utility model content
The purpose of this utility model is to provide a kind of roller bearings device of being convenient to charging-up lubricant oil.
For reaching above-mentioned purpose, the technical scheme that the utility model adopts is: a kind of Drum Shaft of Rig Drawworks bearing apparatus of being convenient to inject lubricating oil is provided, it is characterized in that: comprise cylinder, the two ends of cylinder are all fixed with bearing seat and empty set bearing box, empty set bearing box is fixed on the inner side of bearing seat by bearing cap shim a, and is fixed with axle sleeve between the two; Between the periphery of axle sleeve and bearing cap shim a, seal by bearing cap shim sealing shroud, and be provided with circulation road between axle sleeve and bearing cap shim sealing shroud, circulation road is communicated with the oil duct of bearing seat;
The outside of bearing seat is provided with the bearing cap shim b of fixed bearing block, and the inside of bearing cap shim b is provided with passage, and this passage is communicated with oil duct and oil pipe, oil pipe access oil inlet.
Preferably, be provided with inner covering and external bushing between empty set bearing box and cylinder, external bushing is arranged between inner covering and empty set bearing box.
In sum, the utlity model has following advantage:
Cylinder is in the time rotating, and lubricating oil enters the passage of bearing cap shim b from oil pipe, and due to bearing cap shim, b fixes, can be along with drum rotating, and lubricating oil enters oil duct along this passage, circulates from oil duct; In this process, because circulation road seals, lubricating oil can not splash, and can be lubricated the bearing in cylinder and empty set bearing box.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Wherein, 1, empty set bearing box; 2, external bushing; 3, inner covering; 4, bearing cap shim a; 5, axle sleeve; 6, bearing seal cover; 7, bearing seat; 8, bearing cap shim b; 9, oil pipe; 10, oil inlet; 11, circulation road; 12, oil duct; 13, passage; 14, cylinder.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail.
As shown in Figure 1, the utility model comprises cylinder 14, and the two ends of cylinder 14 are all fixed with bearing seat 7 and empty set bearing box 1, and empty set bearing box 1 is fixed on the inner side of bearing seat 7 by bearing cap shim a4, and is fixed with axle sleeve 5 between the two.Between the periphery of axle sleeve 5 and bearing cap shim a4, seal by bearing cap shim sealing shroud 6, and be provided with circulation road 11 between axle sleeve 5 and bearing cap shim sealing shroud 6, circulation road 11 is communicated with the oil duct 12 of bearing seat 7.The outside of bearing seat 7 is provided with the bearing cap shim b8 of fixed bearing block 7, and the inside of bearing cap shim b8 is provided with passage 13, and this passage 13 is communicated with oil duct 12 and oil pipe 9, and oil pipe 9 accesses oil inlet 10.
There are respectively a bearing seat 7 and empty set bearing box 1 in the two ends of cylinder 14, and the bearing in bearing seat 7 and empty set bearing box 1 all needs butter lubricated.What generally adopt is all lubricated to bearing seat 7 and 1 dozen of butter of empty set bearing box separately.Butter of the present utility model enters empty set bearing box 1 through the circulation road 11 in reserved bearing cap shim b4.The structure of this circulation road 11 is made up of the bearing cap shim a4 on bearing seat 7 and empty set bearing box 1, axle sleeve 5 and bearing cap shim sealing shroud 6.While injecting lubricating oil, butter is by alemite, and oil inlet 10 enters oil pipe 9, and the passage of the bearing cap shim b8 that flows through enters bearing seat 7, then enters empty set bearing box 1 by the circulation road 11 between bearing cap shim sealing shroud 6 and axle sleeve 5.
Between empty set bearing box 1 and cylinder 14, be provided with inner covering 3 and external bushing 2, external bushing 2 is arranged between inner covering 3 and empty set bearing box 1.
Although by reference to the accompanying drawings the specific embodiment of the present utility model is described in detail, should not be construed as the restriction of the protection domain to this patent.In the described scope of claims, the various modifications that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
