Abstract
The utility model relates to the technical field of manufacturing of motor bearings, and in particular relates to a sealing device of a motor bearing. The sealing device comprises a first sealing component and a second sealing component which are combined, wherein the first sealing component is arranged along the outer circumference of an inner ring of the bearing; the second sealing component is arranged along the inner circumference of an outer ring of the bearing; and two annular bulges are arranged on the second sealing component and are in fit with the first sealing component. By adopting the sealing device of the motor bearing, a clearance can be filled, the torque load can be increased, invasion of foreign matters can be prevented, and the damage can be reduced.
Description
Technical field
The utility model relates to motor bearings manufacturing technology field, especially a kind of seal arrangement of motor bearings.
Background technique
Motor bearings is when being subject to the load rotation, and the raceway of Internal and external cycle or the face of rolling element, can be cataphracted phenomenon due to fatigue.
The model utility content
In order to overcome the deficiency of existing technology, the utility model provides a kind of seal arrangement of motor bearings.
The utility model solves the technological scheme that its technical problem adopts: a kind of seal arrangement of motor bearings, the Sealing one and the Sealing two that comprise combination, described Sealing one is around the circumferencial direction of bearing inner race outside, the circumferencial direction of described Sealing two threaded shaft bearing outer-ring inner edges, described Sealing two is provided with the twice annular projection, described annular projection gluing, sealing part one.
According to another embodiment of the present utility model, further comprise that described Sealing one is provided with ripple with the bearing surface of contact.
The beneficial effects of the utility model are, but the utility model filling chink increases the moment load, prevent the foreign matter intrusion, reduce damage.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
In figure 1, Sealing one, 2, Sealing two, 3, annular projection, 4, ripple.
Embodiment
As Fig. 1 is structural representation of the present utility model, a kind of seal arrangement of motor bearings, the Sealing 1 and the Sealing 22 that comprise combination, described Sealing 1 is around the circumferencial direction of bearing inner race outside, the circumferencial direction of described Sealing 22 threaded shaft bearing outer-ring inner edges, described Sealing 22 is provided with twice annular projection 3, described annular projection 3 gluing, sealing parts 1.Described Sealing 1 is provided with ripple 4, the able to increase force moment load with the bearing surface of contact.
The Sealing 1 of being made by rubber is fixed on the inner ring periphery, bonding with the annular projection 3 of Sealing two, forms a resilient space between the two, can store certain lubricant oil, for bearing lubrication.And flexibility is large, adjustment and installation is convenient.
But the utility model filling chink, increase the moment load, prevent the foreign matter intrusion, reduce damage.
Claims (2)
