Abstract

The utility model discloses a take circular cone bearing inner circle of O type circle structure relates to tapered roller bearing field, one side of bearing inner circle is big terminal surface, and the opposite side is little terminal surface, the mounting groove has been seted up on the big terminal surface of bearing inner circle for put into O type circle, the internal diameter of bearing inner circle is used for the cover to establish on mounting base's external diameter, mounting base's installation face is used for the extrusion O type circle makes O type circle warp, thereby will big terminal surface with the installation face is sealed. The utility model has the advantages that: through at the big terminal surface fillet department of circular cone inner circle, increase O type rubber circle, let the inner circle terminal surface have sealing function, solved some sealed demand's problem, for the customer creates the value, for the enterprise creates the profit.

Description

Conical bearing inner ring with O-shaped ring structure

Technical Field

The utility model relates to a tapered roller bearing's field, concretely relates to take tapered roller bearing inner circle of O type circle structure.

Background

The existing cone inner ring design structure has no end face sealing function. Therefore, when the existing conical bearing is used in an application scene needing end face sealing, the existing design structure has no sealing measure, and the application cannot be met.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the not enough of prior art existence, and provide a take circular cone bearing inner circle of O type circle structure, solve circular cone inner circle end face seal problem, through increasing O type rubber ring for circular cone inner circle has the end face seal function.

The purpose of the utility model is accomplished through following technical scheme: the utility model provides a take circular cone bearing inner circle of O type circle structure, one side of bearing inner circle is big terminal surface, and the opposite side is little terminal surface, seted up the mounting groove on the big terminal surface of bearing inner circle for put into O type circle, the internal diameter of bearing inner circle is used for the cover to establish on the external diameter of mounting base, the installation face of mounting base is used for the extrusion O type circle makes O type circle warp, thereby will big terminal surface with the installation face is sealed.

As a preferable technical scheme, the mounting groove and the inner diameter of the bearing inner ring are in transition through a fillet.

As a preferable technical scheme, the depth of the mounting groove is smaller than the height of the O-shaped ring, and the outer side surface of the O-shaped ring is ensured to extend out of the large end surface of the bearing inner ring after mounting.

The utility model has the advantages that: through at the big terminal surface fillet department of circular cone inner circle, increase O type rubber circle, let the inner circle terminal surface have sealing function, solved some sealed demand's problem, for the customer creates the value, for the enterprise creates the profit.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a schematic view of the installation structure of the present invention and the installation base.

Fig. 3 is a partially enlarged view of the area a in fig. 2.

Description of the reference numerals: the bearing comprises a bearing inner ring 1, a large end face 1-1, a small end face 1-2, a mounting groove 1-3, an inner diameter 1-4, a fillet 1-5, an O-shaped ring 2, a mounting base 3, an outer diameter 3-1 and a mounting surface 3-2.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings:

example (b): referring to fig. 1, one side of a conical bearing inner ring with an O-ring structure is a large end surface 1-1, and the other side is a small end surface 1-2, as shown in fig. 1-3. The large end face 1-1 of the bearing inner ring 1 is provided with a mounting groove 1-3 for placing the O-shaped ring 2, preferably, the depth of the mounting groove 1-3 is smaller than the height of the O-shaped ring 2, so that the outer side face of the O-shaped ring 2 is ensured to extend out of the large end face 1-1 of the bearing inner ring 1 after mounting (as shown in fig. 1). Referring to fig. 2 and 3, when the inner diameter 1-4 of the bearing inner ring 1 is sleeved on the outer diameter 3-1 of the mounting base 3, the mounting surface 3-2 of the mounting base 3 presses the O-ring 2, so that the O-ring 2 is deformed, and the large end surface 1-1 is sealed with the mounting surface 3-2 (as shown in fig. 3).

Preferably, as shown in fig. 1 and 3, the mounting grooves 1-3 and the inner diameter 1-4 of the bearing inner ring 1 are transited through fillets 1-5.

The utility model discloses offer mounting groove 1-3 on 1 big terminal surface 1-1 of bearing inner circle of conical bearing to put into O type circle 2, when bearing inner circle 1's internal diameter 1-4 cover was established on mounting base 3's external diameter 3-1, mounting base 3's installation face 3-2 can extrude O type circle 2 makes O type circle 2 take place to warp to fill up all clearances between big terminal surface 1-1 and the installation face 3-2, can effectively block steam, dust, greasy dirt infiltration, thereby make the conical inner circle terminal surface have sealed function, extensively be applicable to the application scene that needs end face seal.

It should be understood that the technical solutions and the inventive concepts of the present invention as equivalent as those of the skilled in the art should be replaced or changed by the claims.

Claims
