Description
Technical Field
The utility model relates to the field of machinary, specific sealed good ironcasting structure that says so.
Background
The existing iron casting structure comprises an iron casting and a movable shaft penetrating through the iron casting, wherein the movable shaft can slightly move left and right, and industrial lubricating oil must be added between the movable shaft and a shaft hole of the iron casting to reduce the abrasion between the movable shaft and the iron casting. At present, two sealing rings are used for sealing industrial lubricating oil on the left and right of an iron casting product, so that the leakage of the industrial lubricating oil is prevented, but along with the prolonging of the service life, the iron casting has the phenomenon of loose tissue, so that the leakage or seepage of the industrial lubricating oil is caused.
SUMMERY OF THE UTILITY MODEL
The utility model provides a well sealed ironcasting structure, its main aim at overcome the sealed mode of current ironcasting and cause the phenomenon of industry lubricating oil seepage easily.
In order to solve the technical problem, the utility model adopts the following technical scheme:
a well-sealed iron casting structure comprises an iron casting and a movable shaft, wherein the middle part of the iron casting is provided with a stepped shaft hole which is communicated with the left and the right, the stepped shaft hole comprises a left shaft hole and a right shaft hole which are communicated with each other, the inner diameter of the right shaft hole is larger than that of the left shaft hole, a bearing matched with the right shaft hole is arranged in the right shaft hole, an oil seal is arranged in the left shaft hole, a movable gap is arranged between the oil seal and the left end of the bearing, a limit retainer ring connected with the iron casting is arranged in the right shaft hole, the limit retainer ring is abutted against the right end of the bearing, the left end of the movable shaft sequentially passes through the limit retainer ring, the bearing and the oil seal, the movable shaft comprises a left shaft part, a middle shaft part and a right shaft part, the diameters of the left shaft part, the middle shaft part and the right shaft part are sequentially increased, the middle shaft part is matched with the bearing and the oil seal, the right shaft part is positioned on the right side of the right end of the bearing, the middle shaft part is provided with a shaft check ring, and the shaft check ring is positioned in the movable gap.
Further, the bearing comprises two single-row radial ball bearings which are arranged right and left in an adjacent mode.
Furthermore, the middle shaft part is provided with a first clamping groove, the shaft check ring is clamped on the first clamping groove, a second clamping groove is arranged in the right shaft hole, and the limiting check ring is clamped on the second clamping groove.
From the above description of the present invention, compared with the prior art, the present invention has the following advantages: the utility model discloses novel structure, design benefit, iron casting structure adopt bearing and oil blanket dual seal's mode to can not direct contact between loose axle and the iron casting, even the iron casting takes place to organize loose phenomenon, industrial lubricating oil also hardly goes out from taking place to organize loose local seepage under the effect of bearing.

Fig. 2 is a schematic cross-sectional view of an iron casting according to the present invention.
Fig. 3 is a schematic front view of the movable shaft of the present invention.
Detailed Description
Refer to fig. 1 to 3. A well-sealed iron casting structure comprises an iron casting 1 and a movable shaft 2, wherein a left stepped shaft hole and a right stepped shaft hole which are communicated are formed in the middle of the iron casting 1, the stepped shaft holes comprise a left shaft hole 3 and a right shaft hole 4 which are communicated with each other, and the inner diameter of the right shaft hole 4 is larger than that of the left shaft hole 3. A bearing 5 matched with the right shaft hole 4 is arranged in the right shaft hole 4, an oil seal 6 is arranged in the left shaft hole 3, a movable gap 7 is arranged between the oil seal 6 and the left end of the bearing 5, a limiting check ring 8 connected with the iron casting 1 is arranged in the right shaft hole 4, and the limiting check ring 8 is abutted against the right end of the bearing 5. The left end of loose axle 2 passes spacing retaining ring 8, bearing 5 and oil blanket 6 in proper order, loose axle 2 includes left axial region 21, well axial region 22 and the right axial region 23 that the diameter increases in proper order, well axial region 22 and bearing 5 and 6 looks adaptations of oil blanket, right axial region 23 is located the right-hand member right side of bearing 5, well axial region 22 is equipped with for the shaft retaining ring 9, and this for the shaft retaining ring 9 is located clearance 7.
Refer to fig. 1 to 3. The bearing 5 comprises two single-row radial ball bearings which are arranged right and left in an adjacent mode. The middle shaft part 22 is provided with a first clamping groove 24, the shaft check ring 9 is clamped on the first clamping groove 24, a second clamping groove 41 is arranged in the right shaft hole 4, and the limiting check ring 8 is clamped on the second clamping groove 41. When the movable shaft 2 moves leftwards, the left end surface of the right shaft part 23 is abutted against the right end surface of the bearing 5, so that the distance of the left movement of the movable shaft 2 is limited; when the movable shaft 2 moves rightward, the shaft stopper 9 abuts against the left end surface of the bearing 5, thereby restricting the rightward movement distance of the movable shaft 2.
Refer to fig. 1 to 3. The utility model discloses a main design principle as follows: the iron casting structure adopts a double-sealing mode of the bearing 5 and the oil seal 6, the movable shaft 2 and the iron casting 1 cannot be in direct contact, and even if the iron casting 1 has a loose structure, industrial lubricating oil is difficult to leak out from the loose structure under the action of the bearing 5.
The above-mentioned be the utility model discloses a concrete implementation way, nevertheless the utility model discloses a design concept is not limited to this, and the ordinary use of this design is right the utility model discloses carry out immaterial change, all should belong to the act of infringement the protection scope of the utility model.
