Abstract
The utility model relates to a laminating drum bearing of a tyre building machine. The innovation point of the laminating drum bearing is that the laminating drum bearing comprises a bearing pin; a pair of annular bumps is arranged in the middle of the bearing pin; self-lubricating bearing rings are sleeved on the annular bumps; and bearing sleeves are sleeved outside the self-lubricating bearing rings. In use, two ends of the bearing pin are arranged on a shrinkage plate of the tyre building machine; the bearing sleeves are arranged inside a guide groove of a keel rack; and a bearing drives the keel rack to move along the radial direction of the shrinkage plate to achieve shrinkage or expansion by axial movement of the shrinkage plate. The bearing is matched with the bearing sleeves by the self-lubricating bearing rings to achieve sliding coordination, therefore, the laminating drum bearing has good lubricating effect and wear resistance without lubricating maintenance, and the service life is greatly improved.
Description
Technical field
The utility model relates to a kind of tyre building machine laminating drum bearing, particularly a kind of tyre building machine laminating drum bearing of long service life.
Background technique
Full-steel radial ply one-through tire forming machine is the visual plant that tire is made, and its laminating drum bearing is used for the keel shoe spreading of laminating drum or rolls in the guiding groove of keel shoe when shrinking.Traditional laminating drum bearing is deep groove ball bearing, and the inner ring installation shaft of deep groove ball bearing is consigned, and the two ends of bearing pin are fixed on the shrink disk that keel shoe is installed.The shortcoming of this kind structure is: bearing very easily weares and teares, and needs to change frequently to safeguard, replacing safeguards then to need to shut down and carry out that impact is produced normally.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of tyre building machine laminating drum bearing of long service life.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of tyre building machine laminating drum bearing, its innovative point is: comprise bearing pin, the middle part of described bearing pin arranges a pair of annular protrusion, be set with the self oiling bearing circle on the described annular protrusion, described self oiling bearing circle is set with bearing housing outward.
Further, the surface roughness of described annular protrusion is the 0.7-0.9 micron.
Further, the inside and outside circle surface roughness of described bearing housing is the 0.7-0.9 micron.
The utility model has the advantage of: during use, the two ends of bearing pin are installed on the shrink disk of tyre building machine, bearing housing is positioned at the guiding groove of keel shoe, utilizes moving axially of shrink disk, drives keel shoe by bearing and realizes shrinking or spreading along moving radially of shrink disk.Bearing adopts the self oiling bearing circle to cooperate with bearing housing and realizes being slidingly matched, and sliding effect is good, and is wear-resistant, need not lubricated maintenance, greatly improved working life.
Description of drawings
Fig. 1 is the utility model tyre building machine laminating drum bearing structure schematic representation.
Embodiment
As shown in Figure 1, comprise bearing pin 1, annular protrusion 2, self oiling bearing circle 3, bearing housing 4.
The middle part of above-mentioned bearing pin 1 is provided with a pair of annular protrusion 2, is set with self oiling bearing circle 3 on the annular protrusion 2, self oiling bearing circle 3 outer suit bearing housings 4.The surface roughness of annular protrusion 2 is the 0.7-0.9 micron.The inside and outside circle surface roughness of bearing housing 4 is the 0.7-0.9 micron.
During use, the two ends of bearing pin are installed on the shrink disk of tyre building machine, and bearing housing 4 is positioned at the guiding groove of keel shoe, utilizes moving axially of shrink disk, drive keel shoe by bearing and realize shrinking or spreading along moving radially of shrink disk.Bearing adopts the self oiling bearing circle to cooperate with bearing housing and realizes being slidingly matched, and sliding effect is good, and is wear-resistant, need not lubricated maintenance, greatly improved working life.
