Embodiment 1

[0015] Embodiment 1: as figure 1 , figure 2 and image 3 As shown, a double outer ring full ball bearing includes an inner ring 1, a first outer ring 2 and balls 3, and the inner ring 1 and the first outer ring 2 are respectively provided with raceways.

[0016] In order to facilitate loading of balls, the first outer ring 2 is composed of two half outer rings 21 arranged symmetrically. The two outer ring halves 21 are clamped by the second outer ring 4 .

[0017] The overall section of the raceway is set according to a regular octagon 8, which is circumscribed on the circumference of the ball 3, and the contact between a longest diagonal 9 of the regular octagon 8 and the two half outer rings face overlap.

[0018] The corresponding positions of the inner ring 1 and the first outer ring 2 are provided with sealing grooves, and a rubber sealing ring 5 is provided in the sealing grooves, and the rubber sealing ring 5 is made of NBR.

[0019] On the outside of the rubber s...

Abstract

The invention discloses a double-outer-ring full ball bearing. The double-outer-ring full ball bearing comprises an inner ring, a first outer ring and a ball, wherein rolling channels are correspondingly formed in the inner ring and the first outer ring. The double-outer-ring full ball bearing is characterized in that the first outer ring is composed of two symmetricalhalf outer rings; the two half outer rings are clamped through a second outer ring; sealing grooves are formed in the corresponding positions of the inner ring and the first outer ring, and rubber sealing rings are arranged in the sealing grooves in a matching manner; retainer rings are tightly clamped on the outer sides of the rubber sealing rings and between the second outer ring and the first outer ring; and the inner sides of the retainer rings are stuck with second rubber rings which are matched with the rubber sealing rings in an abutting manner; and sealing lips, which are in abutting contact with the first outer ring and the inner ring, are arranged on the inner sides of the rubber sealing rings.

Description

technical field [0001] The invention relates to a bearing, especially a full ball bearing. Background technique [0002] The full ball bearing can keep the arrangement of the rolling elements in the bearing raceway at a fixed distance, prevent the running of balls, avoid the rolling elements from biting each other, and at the same time make the rolling elements evenly distributed along the circumference, reducing the bearing clearance caused by the movement during operation. Adverse effects; when the cage is not used, the full ball arrangement can be selected to prolong the bearing life or enhance the bearing accuracy. However, the filling of rolling elements of full ball bearings has always been a difficult problem, and the sealing of full ball bearings is also a problem that needs to be considered. Contents of the invention [0003] The present invention aims at the above problems and provides an easy-to-fill and well-sealed double-outer-ring full-ball bearing. The pre...
