Abstract
The utility model discloses a sealing structure of a motor bearing chamber, which comprises a bearing chamber composed of an inner cover, an outer cover and an end cover; a bearing is arranged in the bearing chamber; a shaft penetrates the bearing chamber from outside and is connected to the bearing; the structure is characterized in that a ring of grooves is arranged at inner side of the inner cover near the shaft; and axial surface oil seal is arranged in the grooves. The sealing structure disclosed by the utility model is radial oil seal; oil is sealed by utilizing friction between lip of the oil seal and the side surface of the inner cover; and the sealing structure is simple in structure and good in sealing effect.
Description
Technical field
The utility model relates to the bearing chamber hermetically-sealed construction of a kind of motor, particularly a kind of asynchronous machine.
Background technology
Because high speed rotating can produce negative pressure, the lubricating oil in the bearing chamber can inwardly trickle under action of negative pressure during asynchronous machine work, and causing the stator winding surface is thin oil everywhere.General solution is on axle and the inner cap contact-making surface oil duct labyrinth type to be set to seal, or adopts the felt collar oil sealing, but effect is unsatisfactory.
The utility model content
The purpose of the utility model is in order to overcome the shortcoming of the described hermetically-sealed construction of background technology, to invent a kind of motor bearings chamber hermetically-sealed construction of good sealing effect.
This motor bearings chamber hermetically-sealed construction comprises by inner cap, enclosing cover and end cap constituting bearing chamber the set inside bearing; Axle penetrates the bearing chamber connection bearing from the outside; It is characterized in that: near the position of axle, be provided with a circle groove in the inboard of inner cap, the axial plane oil sealing is set in the groove.
The utility model is a kind of radially oil sealing, utilizes the friction of side of lip and the inner cap of oil sealing to come oil sealing, good sealing effect.
Description of drawings
Fig. 1, the structure chart of the utility model.
Embodiment
The concrete structure of accompanying drawings the utility model.
Fig. 1 is the cross section view of common bearing chamber, and inner cap 3, enclosing cover 6 and end cap 4 are a seal by bolt, forms bearing chamber, set inside bearing 2.Axle 1 penetrates bearing chamber by the outside through inner cap 3, and bearing 2 is socketed on the axle 1.In the inboard of inner cap 3, near the position of axle, be provided with a circle groove, be provided with axial plane oil sealing 5 in the groove.Utilization utilizes the friction of side of lip and the inner cap of oil sealing to come oil sealing.
Above embodiment is a kind of execution mode of the utility model; But not to the restriction of the utility model right; Those skilled in that art, the equivalent transformation of on the utility model scheme basis, making and other not creative variations all are interpreted as falling into the utility model protection range.
