Description

Insert bearing seat with sealing function

Technical Field

The utility model relates to an insert bearing machinery, especially an insert bearing frame with sealing function.

Background

At present, the bearing assembly with the seat on the outer spherical surface in the prior art is mainly used for equipment such as agricultural machinery, mining machinery, conveying belts and the like; the service life of the outer spherical bearing is mainly determined by the influence of two factors; one is the manufacturing quality of the bearing itself; the other is the determination of the lubrication quality of the bearing in the using process; the outer spherical bearing is provided with a sealing device and a special structure and mounting mode of the outer spherical bearing seat, so that the existing outer spherical bearing seat is not provided with the sealing device, and the bearing is in direct contact with the external environment in the use process; the bearing service failure condition is analyzed from the prior bearing service failure condition, most of the reasons are that the sealing element of the bearing can not prevent external dirt from invading the inside of the bearing, so that the bearing is seriously abraded, and the service life of the bearing is greatly reduced.

Disclosure of Invention

To the situation, for solving the problem that exists among the prior art, the utility model aims at providing an insert bearing frame with sealing function, solve and do not contain sealing device on the bearing frame among the prior art for inside external filth invades the bearing easily, cause bearing wear serious, make the life greatly reduced's of bearing problem.

The technical scheme for solving the problem is as follows: the spherical bearing support comprises an outer spherical bearing support, wherein an outer spherical bearing is arranged in the support, the left end and the right end of the support are respectively provided with an annular oil seal groove, the oil seal grooves are coaxial with the spherical bearing, and each oil seal groove is internally provided with a sealing ring.

Preferably, the sealing ring can be arranged as a framework oil seal.

Preferably, the outer diameter of the oil seal groove is larger than the outer diameter of the spherical bearing.

Preferably, the inner circular surface of the sealing ring is tightly attached to the outer circular surface of the inner ring of the spherical outer bearing, so that the sealing effect is realized.

The utility model discloses think about novelty, the structure is ingenious, and the practicality is strong, carries out double-deck sealedly through the dust keeper that skeleton oil blanket and insert bearing self carried, and the reduction dust that can be very big gets into the inside probability of bearing to make the bearing can keep and prolong better lubricated state, thereby prolong the life of bearing greatly.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

By figure 1 to figure 3, the utility model discloses an insert bearing support 1, installation insert bearing 2 in the support, an annular oil blanket recess 3 has respectively been seted up at both ends about insert bearing support 1, and oil blanket recess 3 is coaxial with insert bearing 2, every oil blanket recess 3 in respectively install a sealing washer 4.

The sealing ring 4 can be arranged as a framework oil seal.

The outer diameter of the oil seal groove 3 is larger than the diameter of the outer circle of the outer spherical bearing 2.

The inner circle surface of the sealing ring 4 is tightly attached to the outer circle surface of the inner ring of the outer spherical bearing 2, so that the sealing effect is realized.

When the device is used, the outer spherical bearing 2 is installed into the outer spherical bearing support 1, then a framework oil seal is respectively installed in each oil seal groove 3, after the device is installed, the outer aid of the framework oil seal is tightly attached to the inner circular surface of each oil seal groove 3 to play a role in fixing, and the inner circle of the framework oil seal is tightly sleeved on the outer circular surface of the inner ring of the bearing, so that the sealing effect is achieved.

This device is at the during operation, installation axle 5 is installed on outer spherical bearing 2, the cooperation of skeleton oil blanket and outer spherical bearing 2's inner circle, the most dust has been blocked, only the dust of few parts can enter into skeleton oil blanket the inside, and the dust keeper who enters into the few parts dust of the inside just very easily carried by outer spherical bearing 2 self blocks, thus, the dust keeper who carries through skeleton oil blanket and outer spherical bearing 2 self carries out double-deck sealedly, the inside probability of reduction dust entering bearing that can be very big, thereby make the bearing can keep and prolong better lubricated state, thereby prolong the life of bearing greatly.

It should be noted that in this solution, the mounting hole between the insert bearing support 1 and the insert bearing 2 and the oil seal groove 3 may be set according to the size of the insert bearing 2 of different specifications and shapes, thereby realizing the insert bearing 2 suitable for different specifications.

The utility model discloses a set up two oil blanket recesses 3 on the support and install the skeleton oil blanket in oil blanket recess 3, can avoid the bearing to expose for a long time in the dust state to can prevent that the dust from entering into inside the bearing, make the bearing can keep and prolong better lubricated state, thereby prolong the life of bearing greatly.

The utility model discloses a set up two oil blanket recesses 3 on spherical outside surface support, just can assemble the oil blanket, relative rather than other sealed modes, processing is simple, and the cost is lower to more do benefit to mass production.

The utility model discloses think about novelty, the structure is ingenious, and the practicality is strong, carries out double-deck sealedly through the dust keeper that skeleton oil blanket and 2 self carry of spherical outside surface bearings, and the reduction dust that can be very big gets into the inside probability of bearing to make the bearing can keep and prolong better lubricated state, thereby prolong the life of bearing greatly.
