Description
Technical Field
The utility model belongs to double helix oil press field, in particular to duplex bearing limit structure in double helix oil press.
Background
The double-screw oil press is a screw oil press which is provided with two pressing screws which operate in opposite directions in the same pressing cage, and is a widely applied oil press at present. The rotating shaft is arranged in the gear box of the double-screw oil press, and the two ends of the rotating shaft are provided with the common roller bearings, so that the bearing capacity ratio is poor, and the service life is short. After the tapered roller bearing is adopted, the tapered roller bearing is easy to have a blocking fault due to the fact that a rotating shaft is heated and extended.
Disclosure of Invention
In view of the technical problem that the background art exists, the utility model provides a duplex bearing limit structure in double helix oil press compares original single bearing, has improved the bearing capacity, has increased life, and tapered roller bearing is difficult for appearing the dead trouble of card.
In order to solve the technical problem, the utility model discloses following technical scheme has been taken and has been realized:
a double-bearing limiting structure in a double-screw oil press comprises tapered roller bearings arranged at two ends of a rotating shaft, wherein a circle of oblique rollers are arranged in the tapered roller bearings, the tapered roller bearings comprise a first tapered roller bearing and a second tapered roller bearing, the first tapered roller bearing and the second tapered roller bearing are coaxially arranged, and the rollers in the first tapered roller bearing and the second tapered roller bearing are symmetrically arranged in a V shape; an adjusting sleeve is arranged between the first tapered roller bearing and the second tapered roller bearing, and bearing sleeves are arranged outside the first tapered roller bearing, the second tapered roller bearing and the adjusting sleeve.
In the preferred scheme, bearing housing one end be equipped with the closing cap, the bearing housing other end is equipped with spacing string platform, axis of rotation tip detachably is equipped with the baffle, first tapered roller bearing and second tapered roller bearing are located the space setting between baffle and the spacing string platform.
In a preferred scheme, a thermal extension gap is arranged between the second tapered roller bearing and the sealing cover.
In a preferred scheme, a round hole is formed in the sealing cover.
This patent can reach following beneficial effect:
two disc conical roller bearings are arranged at two ends of a rotating shaft in the reduction gear box, so that the bearing capacity of the bearings is improved, and the service life of the double-bearing limiting structure is prolonged. The adjusting sleeve provides clearance between the tapered roller bearings, and the running stability of the bearings is improved. The first tapered roller bearing is fixed, and one side of the second tapered roller bearing is provided with a thermal extension gap; the thermal elongation phenomenon of the rotating shaft in the working process can not cause the blockage of the tapered roller bearing.
Drawings
The invention will be further explained with reference to the following figures and examples:
fig. 1 is a schematic view of a double-bearing limiting structure of the present invention;
FIG. 2 is an enlarged view of FIG. 1 at A;
FIG. 3 is a cross-sectional view of the bearing housing of the present invention;
fig. 4 is a diagram showing a positional relationship between the first tapered roller bearing and the second tapered roller bearing according to the present invention;
fig. 5 is a three-dimensional structure diagram of the bearing sleeve of the present invention.
In the figure: the device comprises a first tapered roller bearing 1, a second tapered roller bearing 2, an adjusting sleeve 3, a bearing sleeve 4, a sealing cover 5, a circular hole 51, a limiting hanging table 6, a baffle 7, a thermal extension gap 8 and a rotating shaft 9.
Detailed Description
A preferable scheme is as shown in fig. 1 to 5, the double-bearing limiting structure in the double-screw oil press comprises tapered roller bearings arranged at two ends of a rotating shaft 9, a circle of oblique rollers are arranged in the tapered roller bearings, the tapered roller bearings comprise a first tapered roller bearing 1 and a second tapered roller bearing 2, the first tapered roller bearing 1 and the second tapered roller bearing 2 are coaxially arranged, and rollers in the first tapered roller bearing 1 and the second tapered roller bearing 2 are symmetrically arranged in a V shape; an adjusting sleeve 3 is arranged between the first tapered roller bearing 1 and the second tapered roller bearing 2, and a bearing sleeve 4 is arranged outside the first tapered roller bearing 1, the second tapered roller bearing 2 and the adjusting sleeve 3.
In this technical scheme, set up two tapered roller bearings, first tapered roller bearing 1 and second tapered roller bearing 2 respectively with axis of rotation 9 both ends. Thereby improved duplex bearing limit structure's stability, life is than longer, is equipped with adjusting sleeve 3 between first tapered roller bearing 1 and the second tapered roller bearing 2, and adjusting sleeve 3 is the elastic component, can bear certain deformation, and the length of adjusting sleeve 3 is formed by the grinding machine processing, has guaranteed that the play of each bearing is the best play, has improved the operating stability of bearing.
Further, 4 one ends of bearing housing are equipped with closing cap 5, and 4 other ends of bearing housing are equipped with spacing string platform 6, and axis of rotation tip detachably is equipped with baffle 7, and first tapered roller bearing 1 and second tapered roller bearing 2 are located the space setting between baffle 7 and the spacing string platform 6. A thermally elongated gap 8 is provided between the second tapered roller bearing 2 and the cover 5. The first tapered roller bearing 1 is fixed, and one side of the second tapered roller bearing 2 is provided with a thermal extension gap 8; the thermal elongation phenomenon of the rotating shaft in the working process can not cause the blockage of the tapered roller bearing.
Further, a circular hole 51 is provided on the cover 5. As shown in fig. 1, the left end of the rotating shaft 9 needs to be connected to a gear shaft, so the circular hole 51 provides a penetrating space for the rotating shaft 9.
The working principle of the whole device is as follows:
1. a disc bearing is respectively arranged at two ends of a shaft in a reduction gear box of the original double-screw oil press, and two disc conical roller bearings are respectively arranged at two ends of the shaft instead. The bearing capacity of the double-bearing limiting structure is increased, and the service life of the double-bearing limiting structure is prolonged.
2. Two disc conical roller bearings are respectively arranged at two ends of the shaft; wherein, one disc bearing at each end is provided with a limiting hanging table to prevent the shaft from moving axially; the other disc bearing is not provided with a limit hanging table, and a gap for thermal extension of the shaft is reserved. The thermal elongation phenomenon of the shaft in the working process can not cause the clamping of the conical bearing.
