Description

Bearing with baffle welded on end face of outer ring

Technical Field

The utility model relates to the field of bearings, in particular to a bearing with an outer ring end face welded with a baffle.

Background

The open type deep groove ball bearing is suitable for high-rotation-speed and even extremely high-rotation-speed operation, is very durable, and does not need frequent maintenance. The bearing has the advantages of small friction coefficient, high limit rotation speed and various size range and form changes, is applied to industries such as precise instruments, low-noise motors, automobiles, motorcycles, general machinery and the like, and is the most widely used bearing in the mechanical industry. Mainly bearing radial load and also bearing a certain amount of axial load;

when the open type bearing is used, lubrication is needed through lubricating oil, but the open type bearing possibly causes external grease to enter the bearing due to the open type structure of the open type bearing, so that the internal grease is polluted, and the normal operation of the bearing is influenced.

Disclosure of Invention

In order to overcome the defects in the prior art, the utility model provides the bearing with the baffle welded on the end face of the outer ring, and the baffle is welded on the outer ring of the bearing, and the rubber cover close to the inner ring of the bearing is arranged on the baffle, so that external grease can be effectively prevented or slowed down from entering the bearing, and the requirement of high-speed operation of the bearing is met.

Technical proposal

The utility model provides a bearing of outer lane terminal surface welding separation blade, includes bearing inner circle and bearing outer lane, one of them one side welding of bearing outer lane has the separation blade, the center department of separation blade is provided with the shaft hole, the shaft hole be close to one side of bearing inner circle is provided with the step, the last rubber cap that has set firmly of step.

Further, a gap is reserved between the rubber cover and the bearing inner ring.

Further, the baffle comprises an outer ring, the inner end of the outer ring is connected with an inclined middle ring, the inner end of the middle ring is connected with an inner ring, and the center of the inner ring is provided with the shaft hole.

Further, a welding ring groove is formed in one side wall, far away from the bearing outer ring, of the outer ring, and a welding layer is arranged at the bottom of the welding ring groove.

Further, the middle of the middle ring is inclined in a direction away from the bearing inner ring.

Further, the outer ring is in full-welded connection with the bearing outer ring.

Advantageous effects

Compared with the prior art, the utility model has the following beneficial effects: through welding the separation blade in bearing inner race department to set up the rubber lid of pressing close to the bearing inner race on the separation blade, can effectually avoid or slow down outside grease entering bearing inside, satisfy the high-speed operating requirement of bearing simultaneously.

Detailed Description

For a better illustration of the present utility model, the following description is made with reference to the accompanying drawings and examples:

the utility model discloses a bearing with baffle plates welded on the end face of an outer ring, which comprises a bearing inner ring 1 and a bearing outer ring 2, wherein one side of the bearing outer ring 2 is welded with a baffle plate 7, the center of the baffle plate 7 is provided with a shaft hole 75, one side of the hole 75, which is close to the bearing inner ring 1, is provided with a step 74, and the step 74 is fixedly provided with a rubber cover 3.

Further, a gap is left between the rubber cover 3 and the bearing inner ring 1.

Further, the baffle 7 includes an outer ring 71, an inner end of the outer ring 71 is connected with an inclined middle ring 72, an inner end of the middle ring 72 is connected with an inner ring 73, and the center of the inner ring 73 is provided with the shaft hole 75.

Further, a welding ring groove 5 is provided in a side wall of the outer ring 71 away from the bearing outer ring 2, and a welding layer 6 is provided at the bottom of the welding ring groove 5.

Further, the middle of the middle ring 72 is inclined away from the bearing inner ring 1.

Further, the outer ring 71 is connected with the bearing outer ring 2 by full welding.

Specifically, during welding, firstly, the bearing is assembled, then the bearing outer ring 2 and the baffle plate 7 are positioned and fixed, and then the baffle plate 7 can be welded on the bearing outer ring 2 by melting the welding layer 6;

when the bearing inner ring 1 is connected with the shaft and rotates at a high speed, the baffle 7 is not moved and can form protection, so that external grease is prevented from entering the bearing.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; although the technical solution of the present utility model has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that the technical solution described in the foregoing embodiments may be modified or some of the technical features thereof may be equally substituted; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
