Abstract
The utility model provides a bearing installation structure suitable for aluminum alloy shell, which comprises a bearing outer ring, wherein the bearing outer ring is assembled on the aluminum alloy shell, and the bearing outer ring and a bearing cover plate are mutually matched; one end of the pin is fixedly connected with the bearing cover plate, and the other end of the pin is clamped in the anti-rotation groove. The utility model discloses let the bearing all have the bearing life-span of ideal under any temperature.
Description
Technical Field
The utility model relates to an automotive production technical field, concretely relates to bearing mounting structure suitable for aluminum alloy shell.
Background
At present, bearings are arranged in inner holes of aluminum alloy shells through outer ring interference fit. When the temperature is very low, the holding force of the aluminum alloy shell to the bearing outer ring is too large, and the service life of the bearing is influenced; when the temperature is high, the holding force of the aluminum alloy shell to the bearing outer ring is insufficient, so that the bearing outer ring rotates relative to the shell, the shell is abraded, and the service life of the bearing is influenced finally.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a bearing mounting structure suitable for aluminum alloy shell to the defect of prior art, let the bearing all have the bearing life-span of ideal under any temperature.
The utility model provides a bearing installation structure suitable for aluminum alloy shell, which comprises a bearing outer ring, wherein the bearing outer ring is assembled on the aluminum alloy shell, and the bearing outer ring and a bearing cover plate are mutually matched; one end of the pin is fixedly connected with the bearing cover plate, and the other end of the pin is clamped in the anti-rotation groove.
And the bearing outer ring and the aluminum alloy shell are in small interference fit.
One end of the pin is fixed in the bearing cover plate.
The utility model discloses a pin card on the bearing apron is located in the bearing inner race, prevents effectively that the bearing inner race from producing relative rotation in the casing, effectively avoids the wearing and tearing of bearing inner race, improves its installation stability simultaneously. Therefore, small interference can be adopted between the bearing outer ring and the shell, and the bearing has ideal bearing service life at any temperature.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a schematic view of the bearing outer ring of the present invention.
The bearing comprises a bearing cover plate 1, a pin 2, a bearing outer ring 3, an aluminum alloy shell 4 and an anti-rotation groove 5.
Detailed Description
The invention will be further described in detail with reference to the drawings and the following detailed description, which are provided for the purpose of clearly understanding the invention and are not intended to limit the invention.
As shown in fig. 1, a bearing mounting structure suitable for an aluminum alloy shell comprises a bearing outer ring 3, wherein the bearing outer ring 3 is assembled on an aluminum alloy shell 4, the bearing outer ring 3 is matched with a bearing cover plate 1, the bearing mounting structure is characterized by further comprising a pin 2, and an anti-rotation groove 5 matched with the end part of the pin 2 is arranged on the bearing outer ring 3; one end of the pin is fixedly connected with the bearing cover plate, and the other end of the pin is clamped in the anti-rotation groove 5. One end of the pin 2 is fixed in the bearing cover plate 1, so that the pin 2 and the bearing cover plate are effectively fixed. Because the bearing cover plate is fixedly arranged, the rotation of the bearing outer ring 3 in the circumferential direction is effectively prevented by the matching of the pin 2 and the anti-rotation groove 5, the relative movement between the bearing outer ring 3 and the aluminum alloy shell 4 is avoided, and the abrasion between the bearing outer ring 3 and the aluminum alloy shell is avoided, so that the service lives of the bearing outer ring and the aluminum alloy shell are effectively prolonged; meanwhile, the installation stability of the bearing outer ring 3 in the aluminum alloy shell 4 is strengthened, and the overall safety of the device is further strengthened.
Due to the adoption of the pin, the bearing outer ring 3 can be effectively prevented from rotating relatively in the aluminum alloy shell 4, and the bearing outer ring 3 and the aluminum alloy shell 4 can be in small interference fit, so that the bearing has ideal bearing service life at any temperature.
Details not described in this specification are within the skill of the art that are well known to those skilled in the art.
