Abstract
A high reliability roll end bearing body used for a slat straightener belongs to the technical field of bearings and is used for improving the reliability of equipment. The bearing body comprises a short shaft coaxial with a straightening roll, a shaft end shield and deep groove ball bearings, wherein the deep groove ball bearings and the shaft end shield are sequentially sheathed on the short shaft; the shaft end shield is connected with the end part of the straightening roll through a thread; and the tip of the short shaft relative to the shaft end shield is provided with a thrust ball bearing. The high reliability roller end bearing body can effectively improve the capability of the bearing body in bearing axial force. The deep groove ball bearings are two so that the bearing body is not easy to be damaged when bearing larger radial force. The shaft end shield is provided with a press-fit forced filling oil cup at one end connected with the straightening roll to facilitate refueling the bearing before installation or during overhaul, thus preventing the bearing from damaging due to lack of oil. Compared with the traditional bearing body, the high reliability roll end bearing body can bear greater axial force and radial force and can be well lubricated, thus being longer in service life, greatly improving the reliability of the whole slat straightener and reducing the maintenance cost of the equipment.
Description
Technical field
The utility model relates to a kind of combined bearing body that is installed in the smoothing roll two ends of strip straightener, belongs to technical field of bearings.
Background technology
The external bearing body in tradition strip straightener roll of straightener two ends is generally by forming with coaxial minor axis, axle head cover and the deep groove ball bearing of smoothing roll, deep groove ball bearing and axle head cover are sleeved on the minor axis successively, the axle head cover is connected with the smoothing roll end by screw thread, and concrete structure as shown in Figure 1.Because the smoothing roll working speed is very high, the body of roll can produce very big radial load under the effect of strip tension force, and the bending stress of limit wave can make smoothing roll play vertically, and these factors can cause the deep groove ball bearing frequent breakage, are having a strong impact on normally carrying out of producing.When bearing damages suddenly in process of production, also can cause roll surface to scratch strip, reduce product quality.Therefore, be necessary the structure of smoothing roll bearings at both ends body is improved.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of durable strip straightener high reliability roller end bearing body is provided.
Problem described in the utility model realizes with following technical proposals:
A kind of strip straightener high reliability roller end bearing body, comprise the minor axis coaxial, axle head cover and deep groove ball bearing in the formation with smoothing roll, deep groove ball bearing and axle head cover are sleeved on the minor axis successively, the axle head cover is connected with the smoothing roll end by screw thread, after the improvement, the termination that minor axis is relative with the axle head cover is provided with thrust ball bearing.
Above-mentioned strip straightener is with high reliability roller end bearing body, and described deep groove ball bearing is provided with two, between two deep groove ball bearings, be provided with spacer between thrust ball bearing and the deep groove ball bearing.
Above-mentioned strip straightener high reliability roller end bearing body, the end that described axle head cover is connected with smoothing roll is provided with the press-fit forced filling oil cup.
The utility model has increased thrust ball bearing on the minor axis termination relative with the axle head cover, this bearing can effectively improve the ability that bearing body bears axial force.Deep groove ball bearing is provided with two, makes bearing body be difficult for being damaged when bearing big radial load.The end that the axle head cover is connected with smoothing roll is provided with the press-fit forced filling oil cup, convenient before installation or during maintenance bearing is refueled, and prevents that bearing from damaging because of oil starvation.Compare with traditional bearing body, the utility model can bear bigger axial force and radial load and can access good lubricatedly, thereby has long service life, has improved the reliability of whole strip straightener greatly, has reduced the maintenance cost of equipment.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of traditional bearing body;
Fig. 2 is a structural representation of the present utility model.
Each label is among the figure: 1, smoothing roll; 2, press-fit forced filling oil cup; 3, axle head cover; 4, thrust ball bearing; 5, deep groove ball bearing; 6, minor axis; 7; The end face steel ball; 8; Spacer.
The specific embodiment
Referring to Fig. 1, Fig. 2; traditional bearing body inside has only a dish deep groove ball bearing 5; improve inside, back and increased by two dish bearings; most critical is that the bearing of left end is a thrust ball bearing 4; this dish bearing is used to bear the smoothing roll axial force, protects other bearing not to be damaged, and installs spacer 8 additional between three dish bearings; help the stable of bearing and deposit grease, play long-time lubricated effect.
In addition, increased a standard press-fit forced filling oil cup 2, can before assembling, refuel, avoid dust and iron filings to enter, increased the service life of bearing bearing at the end of thread of axle head cover 3.
