Abstract
The utility model discloses a highly dustproof bearing, belonging to the technical field of bearings. The highly dustproof bearing comprises a roll ball arranged between an inner ring and an outer ring, the roll ball is provided with a retainer, sealing rings I are arranged at the two sides of the roll ball and between the inner ring and the outer ring, and a sealing ring II is fixedly arranged on the outer sidewall of one end of the inner ring. According to the highly dustproof bearing disclosed by the utility model, the sealing ring II is fixedly arranged on the outer sidewall of one end of the inner ring, thus a dustproof effect is improved; and dust hardly enters the space between the inner ring and the outer ring of the bearing so that the service life of the bearing is prolonged.
Description
Technical field
The utility model discloses a kind of high shield bearing, belongs to the technical field of bearing.
Background technique
At present, be used for the bearing on the motor, mainly be made up of inner ring, outer ring, ball, retainer, the both sides of ball also are provided with seal ring between inner ring, outer ring.Because the working environment of motor is more abominable, and rotating speed is high, and dust very easily gets between the inner ring, outer ring of bearing, causes bearing drag to increase, and reduces working life.
Summary of the invention
For addressing the above problem the high shield bearing that the utility model provides a kind of dust to be not easy to get into.
For realizing above-mentioned purpose, the technological scheme that the utility model adopted is:
A kind of high shield bearing comprises the ball that is equipped with between inner ring and outer ring and is with retainer, and the both sides of ball also are provided with seal ring one between inner ring, outer ring, be installed with seal ring two on the end outer side wall of said inner ring.
As the further setting of such scheme, the internal diameter of said seal ring two is not less than the internal diameter of inner ring, and the external diameter of seal ring two is less than the internal diameter of outer ring, greater than the external diameter of inner ring.
Said seal ring two is fixedly mounted on the inner ring through spot welding.
A kind of high shield bearing of the utility model through fixed installation seal ring two on an end outer side wall of inner ring, has improved dustproof effect, makes dust be not easy to get between the inner ring, outer ring of bearing, has prolonged the working life of bearing.
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; A kind of high shield bearing of the utility model; Comprise the ball 4 that is equipped with between inner ring 1 and outer ring 2 and is with retainer 3, the both sides of ball 4 also are provided with seal ring 1 between inner ring 1, outer ring 2, be installed with seal ring 26 on the end outer side wall of inner ring 1.
Wherein, the internal diameter of seal ring 26 is not less than the internal diameter of inner ring 1, and the external diameter of seal ring 26 is less than the internal diameter of outer ring 2, greater than the external diameter of inner ring 1.Seal ring 26 is fixedly mounted on the inner ring 1 through spot welding.
The foregoing description only be used to explain inventive concept of the utility model, but not to the qualification of the utility model rights protection allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into the protection domain of the utility model.
