Abstract
The utility model discloses a vertical gear box with a shaft extending downwards, which comprises a gear box body and a gear shaft extending from the bottom wall of the gear box body; a bearing is arranged on a gear shaft which is arranged in the gear box body, an end cover is arranged between the gear shaft which extendes out of the gear box body and the bottom wall of the box body, an oil retaining cover is sleeved on the gear shaft above the bearing, and an oil inlet hole communicated with an inner cavity of a bearing seat is formed on the outer wall of the bearing seat; an annular groove formed on the side wall of the end cover is communicated with an inner cavity of the bearing, and an oil outlet is formed below the annular groove. Since a relative independent lubricating circuit is established for the bearing, the bearing lubricating oil is infused in from the oil inlet hole formed on the outer wall of the bearing seat, the annular groove on the side wall of the end cover provides a sufficiently large oil storage space for the bearing lubricating oil, and the oil outlet formed below the annular groove causes the stored lubricating oil to return to the oil tank in time; and the oil supply amount of the bearing lubricating oil can be controlled, and the stored oil level is lower than the bonding surface of the end cover and the bearing seat, therefore, the purpose of no oil leakage is achieved.
Description
Technical field
The utility model relates to the vertical gear case, especially relates to a kind of thin oil lubricant bearing shaft extension vertical gear case down.
Background technique
The shaft position of working shaft shaft extension vertical gear case (containing speed reducer etc.) down is owing to be in the state of relatively rotating between the component such as working shaft and end cap, when adopting the thin oil lubricant bearing, conventional method is that pad adds seal ring (one or more) and prevents its leakage of oil between end cap and working shaft.During actual the use, because machining accuracy, seal ring quality and the seal ring phenomenons such as wearing and tearing at work of component are difficult to fundamentally solve the leakage of oil problem.
The model utility content
The purpose of this utility model is to provide a kind of shaft extension vertical gear case down that can fundamentally solve the leakage of oil problem.
For achieving the above object, the utility model can be taked following technical proposals:
Shaft extension described in the utility model vertical gear case down, comprise gear housing and from the extended gear shaft of casing diapire, place the gear shaft in the described gear housing to be provided with bearing, extend between outer gear shaft of gear housing and the casing diapire and be provided with end cap, be set with oil blocking cover on the gear shaft of described bearing top, offer oil inlet hole on the bearing support outer wall of described bearing with its intracavity inter-connection; The annular groove that is opened on the described end cap sidewall is connected with described bearing cavity, offers oil outlet below described annular groove.
Offer the ladder platform on the madial wall of described end cap, fastening on described ladder platform has the sealing baffle of falling the indentation; Between gear shaft below the described sealing baffle and end cap, be provided with axle sleeve.
Described oil outlet place is connected with return tube.
Advantage of the present utility model is to be set with oil blocking cover on the gear shaft of bearing top, enters bearing to prevent the lubricant oil in the gear housing, offers the oil inlet hole with its intracavity inter-connection on the bearing support outer wall; The annular groove that is opened on the end cap sidewall is connected with bearing cavity, offers oil outlet below annular groove.So just set up a relatively independent lubricated circuit to bearing, the oil inlet hole injection bearing lubricant oil of offering from the bearing support outer wall, the annular groove that is opened on the end cap sidewall has given bearing oil with enough big oil storage space, and the oil outlet that the annular groove below is offered can make the lubricant oil of storage in time get back to fuel tank; Because bearing oil gives oil mass controlled, annular groove can oil in reserve and oil return in time, guarantees to store pasta and is lower than the junction plane of end cap and bearing support, thereby accomplish oil-proof fully.
Offer the ladder platform on the madial wall of end cap, fastening on the ladder platform has the sealing baffle of falling the indentation; Junction plane between sealing baffle and the end cap forms zig zag plane, can prevent that the lubricant oil that has splashed from entering the relative movement district, guarantees sealing effect; Between gear shaft below the sealing baffle and end cap, be provided with axle sleeve, can the rigid bearing position.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in the figure, shaft extension described in the utility model vertical gear case down, comprise gear housing 1 and from the extended gear shaft 2 of casing diapire, place the gear shaft 2 in the described gear housing to be provided with bearing 3, extend between outer gear shaft 2 of gear housing 1 and the casing diapire and be provided with end cap 4, be set with shelves oil cover 5 on the gear shaft 2 of bearing 3 tops, offer oil inlet hole 7 on the outer wall of the bearing support 6 of bearing 3 with its intracavity inter-connection; Be opened in annular groove 8 and bearing 3 intracavity inter-connections on end cap 4 sidewalls, below described annular groove 8, offer oil outlet; The oil inlet hole 7 injection bearing lubricant oil of offering from bearing support 6 outer walls, the annular groove 8 that is opened on end cap 4 sidewalls has given bearing oil with enough big oil storage space, and the oil outlet that annular groove 8 belows are offered can make the lubricant oil of storage in time get back in the fuel tank; Because bearing oil gives oil mass controlled, annular groove 8 can oil in reserve and oil return in time, and control stores pasta and is lower than the junction plane of end cap 4 and bearing support 6, thereby accomplishes oil-proof fully; For increasing sealing effect, on the madial wall of end cap 4, offer the ladder platform, on the ladder platform, fasten the sealing baffle of falling the indentation 9, the junction plane between sealing baffle 9 and the end cap 4 forms zig zag plane, can prevent that the lubricant oil that has splashed from entering the relative movement district; Between gear shaft below the sealing baffle 92 and end cap 4, axle sleeve 10 is set, can the rigid bearing position, prolong its working life; 9 places are connected with return tube 11 at oil outlet.
