Description

A kind of universal bearing

Technical field

This utility model belongs to technical field of bearings and in particular to being a kind of universal bearing.

Background technology

Bearing is to rotate one of mechanical requisite spare and accessory parts, and bearing is typically mounted in rotary shaft, and its inner ring is followed Rotary shaft rotates, and outer ring maintains static.

When bearing inner race is sheathed on rotary shaft, it is difficult to ensure that the internal diameter of inner ring is adapted with the external diameter of rotary shaft.As The inwall of fruit inner ring fails to fit tightly rotary shaft, then easily cause the relative slip of inner ring and rotary shaft, thus cannot ensure The normal work of bearing.

Utility model content

The purpose of this utility model is to overcome defect mentioned above and deficiency, and provides a kind of universal bearing.

The technical scheme that this utility model realizes the employing of its purpose is as follows.

A kind of universal bearing, including outer ring, rolling member, inner ring, dust cap and circular cone ring；Described inner ring and outer ring are in all Circular and concentric setting, and rolling member is located between inner ring and outer ring；Described dust cap is fixed on outer ring both sides, and anti- Dirt lid extends internally and is embedded at inner ring side wall；Described circular cone ring has a pair, is divided into inner ring inwall both sides；A pair of circular cone ring leads to Cross bolt to be fixedly connected；Described circular cone ring hollow setting, and circular cone ring outer wall is in round table-like；The inwall of described inner ring is central raised And both sides are fitted with the outer wall of circular cone ring.

Described interior ring outer wall offers caulking groove；The inner bending of described dust cap is L-shaped；The inner of dust cap is embedded at embedding Groove and with caulking groove interval setting.

With four block gaps and identical conical blocks are constituted described circular cone ring.

Described circular cone ring is provided with connecting hole, and described bolt passes through corresponding connecting hole and fixed with nuts and washers.

The gradient of described circular cone ring is at 30 ° -60 °.

This bearing can plug the rotary shaft of different-diameter, to increased this bearing by changing the circular cone ring of different inner diameters Adaptability and versatility, reduce cost.And, this bearing, is embedded at the structure of block piece, improves axle using dust cap the inner Hold seal degree between inner ring, bearing outer ring and dust cap and intensity it is ensured that mechanical transmission mechanism is effectively transported for a long time OK.

Specific embodiment

Below in conjunction with the accompanying drawings, this utility model is described in further detail.

A kind of universal bearing, including outer ring 1, rolling member 2, inner ring 3, dust cap 4 and circular cone ring 5；Described inner ring 3 is with outward Circle 1 is all in circular and concentric setting, and rolling member 2 is located between inner ring 3 and outer ring 1；Described dust cap 4 is fixed on outer Enclose 1 both sides, and dust cap 4 extends internally and is embedded at inner ring 3 side wall；Described circular cone ring 5 has a pair, is divided into inner ring 3 inwall Both sides；A pair of circular cone ring 5 is fixedly connected by bolt 6；Described circular cone ring 5 hollow setting, and circular cone ring 5 outer wall is in round table-like； The inwall of described inner ring 3 is central raised and is fitted with the outer wall of circular cone ring 5 in both sides.

Described inner ring 3 outer wall offers caulking groove 3a；The inner bending of described dust cap 4 is L-shaped；The inner of dust cap 4 is embedding Located at caulking groove 3a and with caulking groove 3a interval setting.

With four block gaps and identical conical blocks 5a is constituted described circular cone ring 5.

Described circular cone ring 5 is provided with connecting hole 5b, and described bolt 6 is through corresponding connecting hole 5b and solid with nuts and washers Fixed.

The gradient of described circular cone ring 5 is at 30 ° -60 °.

The inner L-shaped structure design of dust cap 4 is so that form labyrinth seal structure, favorably between dust cap 4 and inner ring 3 Enter Bearing inner in the seepage preventing lubricating oil and isolation sand and dust.

During use, first rotary shaft is passed through circular cone ring 5 and inner ring 3, then the opposite side of rotary shaft passes through second circular cone Ring 5.By aperture surface that is close for two circular cone rings 5 and pasting tactile inner ring 3, then corresponding connecting hole 5b is passed through to fix circular cone with bolt 6 Ring 5.

This utility model can plug the rotary shaft of different-diameter by changing the circular cone ring 5 of different inner diameters, increased this The adaptability of bearing and versatility, reduce cost.The aperture surface of inner ring 3 is central raised and is fitted with the inclined-plane of circular cone ring 5 in both sides, Provide certain middle axle load for circular cone ring 4.

When needing fixed bias circuit, when bearing axial load, circular cone ring 5 can be by some conical blocks being provided with gap to each other 5a is constituted, and each conical blocks 5a is provided with the connecting hole 5b of insertion.Circular cone ring 5 is by four pieces of radians close to 90 ° of conical blocks 5a is put together, gap cooperation between conical blocks 5a, and every piece of conical blocks 5a is all correspondingly arranged on connecting hole 5b, when corresponding circle Cone block 5a with bolt 6 fixing after it is ensured that every piece of conical blocks 5a all can fixed bias circuit, thus providing enough axial restraints Power.The gap setting of conical blocks 5a is it is ensured that when the diameter of rotary shaft is in rational error, conical blocks 5a can fit rotation Axle.

This utility model is illustrated according to embodiment, and on the premise of without departing from present principles, this device can also be made Go out some deformation and improve.It should be pointed out that the technical scheme that the mode such as all employing equivalents or equivalent transformation is obtained, all fall In protection domain of the present utility model.
