Description

Integrated sealed bearing device

Technical Field

The utility model relates to a bearing device, concretely relates to integrated sealed bearing device.

Background

Oil seals and bearings are key parts of transmission parts such as engines and transmissions of automobiles, the oil seals often isolate the outside air from the inside lubricating oil of the power part shell, and the shaft rotating parts of power transmitters inside the power part shell often need to be supported by the bearings. The power input end and the power output end need bearings to support the shaft rotating parts, the shaft rotating parts extend out of the shell, oil seals are needed to isolate the inside and the outside of the shell, and the oil seals mainly play a role in sealing media inside the shell. Common oil blanket and bearing's design, processing and assembly are all independent separately, and oil blanket and bearing need the connecting piece will assemble on a casing, and it makes oil blanket and bearing cost higher alone, and because not integrated as an organic whole, the axial space of arranging is great, and oil blanket and bearing cooperation, the relative axiality of the outer lane of oil blanket body and bearing between the two reduces, guarantees that better axiality makes the big and processing cost height of the technology degree of difficulty.

Disclosure of Invention

The utility model discloses an integrated sealed bearing device solves the problem that bearing space structure is compact, with low costs, sealing performance promotes.

The utility model discloses an integrated sealed bearing device, which comprises an oil seal body and a bearing; the bearing comprises an outer ring, a rolling body and an inner ring from outside to inside in sequence; the inner cavity of the inner ring is used for passing through the shaft rotating part; the outer ring axially extends in parallel to exceed the axial length of the inner ring, and a support leg extends out of the extending end part towards the axial direction; the oil seal body is positioned in the outer ring and is coaxially arranged with the inner ring side by side, and the inner cavity of the oil seal body is used for passing through the shaft rotating part; the oil seal body is provided with a bracket seat, and the support legs are embedded in the bracket seat; the oil seal body axially extends out of the lip towards the inner ring, and the lip is used for wrapping the shaft body structure.

Further, the lip is covered with a spring which radially compresses the lip 12.

Further, the outer surface of the outer ring is provided with an annular groove, and the sealing ring is arranged in the annular groove of the outer ring.

Further, the annular groove is located above the inner ring.

Further, the oil seal body and the sealing ring are rubber pieces.

Further, the outer ring and the inner ring are metal pieces.

Further, the sealing ring is wavy with salient points.

The utility model discloses beneficial technological effect does: the utility model discloses an integrate oil blanket body and bearing in an organic whole, possess support axle type rotating member and play sealed difunctional, oil blanket body and the integrated design of bearing can reduce connecting piece between the two simultaneously, and axial space is short, the structure compacter can satisfy more spatial arrangement. The outer lane of bearing goes up the direct inlaying of foot in the oil blanket of oil blanket originally internally, has reduced the skeleton that supports the oil blanket body, and oil blanket body and bearing lug connection have reduced connecting piece between the two, and the oil blanket body guarantees easily for the outer lane axiality precision of bearing, effectively reduces the technology degree of difficulty and reduce cost.

Detailed Description

The following describes in detail preferred embodiments of the present invention with reference to the accompanying drawings.

An integrated sealed bearing device comprises an oil seal body and a bearing. The bearing comprises an outer ring 4, a rolling body 5 and an inner ring 6 from outside to inside in sequence. The inner cavity of the inner ring 6 can pass through the shaft rotating part. The rolling body 5 is arranged between the outer ring 4 and the inner ring 6 to reduce the friction force of the relative sliding of the outer ring 4 and the inner ring 6, the inner ring 6 is positioned on the inner side of the rolling body 5 to play a role of supporting the shaft rotating part, and the outer ring 4 is positioned on the outer side of the rolling body 5 to play a role of supporting and fixing. The outer race 4 extends axially parallel over the axial length of the inner race and projects at its extended end in the axial direction by a foot 41. The oil seal body 1 is positioned in the outer ring 4 and is coaxially arranged with the inner ring 6 side by side, and the inner cavity of the oil seal body 1 passes through the shaft rotating part. The oil seal body 1 is provided with a bracket base 13, and the support legs 41 are embedded in the bracket base 13. The oil seal body 1 axially extends out of the lip 12 towards the inner ring 6, and the lip 12 covers the shaft rotating part. The spring 2 is sleeved outside the lip 12, and the spring 2 radially compresses the lip 12 to provide holding force to press the lip 12 of the oil seal onto the shaft rotating part.

The outer surface of the outer ring 4 is provided with an annular groove 42, the annular groove 42 is positioned above the inner ring 6, and a sealing ring 3 is arranged in the annular groove 42 of the outer ring 4. The sealing ring 3 is wave-shaped with salient points 31. The convex points 31 continuously realize multi-layer sealing, the wavy convex parts can be effectively compressed into the space of the wavy concave parts when being installed on the shell, the assembling resistance is reduced, the assembling performance is improved, the sealing ring 3 is not easy to be damaged, and the sealing effect is good.

The oil seal body 1 and the sealing ring 3 are rubber pieces and can effectively play a role in sealing. The outer ring 4 and the inner ring 6 are metal pieces and can effectively support the rotating piece.
