Abstract
The utility model discloses a kind of motor bearing chamber oil baffle disc, its entirety is circular, circular endoporus is the inner hole face coordinating motor shaft, described oil baffle disc axially inner side is annular boss by inner hole face along the Part I that oil baffle disc outward radial extends, the part being continued outward radial extension by annular boss is annular recess, and continuing outward extending part by annular recess is ring-type sloping platform.The utility model reduces the consumption of bearing chamber lubricating oil while ensureing bearing top lubrication, and then reduces the heat of lubricating oil High Rotation Speed generation, reduces the probability of burn bearing.
Description
Technical field
The utility model relates to motor bearing chamber gear oil tech field, particularly motor bearing chamber oil baffle disc.
Background technology
The lubricating condition quality of motor bearings, often determines the useful life of motor bearings.When motor bearings High Rotation Speed, if do not installed oil baffle disc additional, the lubricating oil of Bearing inner can be thrown out of outside bearing end cover due to the effect of centrifugal force.The number of the lubricating oil in bearing chamber, if from lubricant effect, preferably can wrap up upper and lower two of whole bearing, the upper and lower two parts of bearing can be lubricated.But because lubricating oil is thick, if lubricating oil wraps up motor shaft or has certain contact-making surface with motor shaft, so can amount of heat be produced when motor High Rotation Speed, easy burn bearing.
The entirety of existing oil baffle is generally flat circle ring-type, if the lubricating oil liquid level in bearing chamber is lower, only parcel covers bearing bottom, and so when motor runs up, this flat circle ring-type oil baffle cannot ensure the lubrication on bearing top.
Summary of the invention
Goal of the invention of the present utility model is the shortcoming in order to overcome above-mentioned background technology, provides a kind of oil baffle disc that the lubricating oil in bearing chamber can be taken to top by bearing chamber bottom.
The technical solution of the utility model is: a kind of motor bearing chamber oil baffle disc, its entirety is circular, circular endoporus is the inner hole face coordinating motor shaft, it is characterized in that described oil baffle disc axially inner side be annular boss by inner hole face along the Part I that oil baffle disc outward radial extends, the part being continued outward radial extension by annular boss is annular recess, continuing outward extending part by annular recess is ring-type sloping platform, when installing this oil baffle disc additional, described annular boss and bearing rotary inner face near, when motor High Rotation Speed, described annular recess becomes oil storage tank, lubricating oil is taken to bearing top from bearing bottom.
The beneficial effects of the utility model are: structure is simple, easy to process.Utilize sleeve workpiece to push when installing the utility model, annular boss and bearing inner face near, when motor High Rotation Speed, described annular recess becomes oil storage tank.When the lubricating oil liquid level in bearing chamber is lower than motor shaft, such as when lubricating oil liquid level only arrive bearing chamber height three/for the moment, when motor High Rotation Speed, annular recess also can take lubricating oil to bearing top from bearing bottom, while ensure that bearing top lubrication, greatly reduce again the consumption of bearing chamber lubricating oil, greatly reduce the heat that lubricating oil High Rotation Speed produces, reduce the probability of burn bearing.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model is installed on motor bearings;
Fig. 2 is sagittal plane figure of the present utility model;
Fig. 3 is axial section of the present utility model;
Fig. 4 is perspective view of the present utility model;
Wherein: 1, lubricating cup, 2, fatten passage, 3, bearing, 4, oil storage tank lubricating oil, 5, oil baffle disc, 6, bearing grease room, 7, lubricating oil, 8, motor shaft, 31, bearing rotary inner face, 51, inner hole face, 52, annular boss, 53, annular recess, 54, ring-type sloping platform.
Embodiment
As shown in Figure 1, lubricating cup (1) is positioned at above motor, fatten passage (2) is provided with bottom lubricating cup, described fatten channel bottom passes into bearing grease room (6), the liquid level of lubricating oil (7) is in bottom, bearing grease room, lubricating oil liquid level is lower than motor shaft (8), and oil baffle disc (5) is enclosed within motor shaft.
As Fig. 2, oil baffle disc (5) shown in Fig. 3, it is inner side axially, towards the side of bearing rotary inner face (31) when namely installing, be annular boss (52) by inner hole face (51) along the Part I that oil baffle disc outward radial extends, the part being continued outward radial extension by annular boss is annular recess (53), continuing outward extending part by annular recess is ring-type sloping platform (54), oil baffle disc is overall electroplates circular thin plate for carbon steel, its thickness is 1.4 ~ 1.6mm, angle between the annular recess of the axial inboard portion of oil baffle disc and ring-type sloping platform axis is 150 ~ 160 degree.
As shown in Figure 1, Figure 2, Figure 3, Figure 4 when installing this oil baffle disc (5) additional, described annular boss and bearing rotary inner face near, annular recess is submerged in lubricating oil (7), when motor High Rotation Speed, due to spacing near face respectively by ring-type sloping platform and annular boss and bearing rotating shaft inner face of the upper and lower two ends of annular recess, annular recess becomes oil storage tank, and oil storage tank lubricating oil (4) is taken to bearing top by from bearing bottom.
Claims (3)
