[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide roller mounted on a pallet of a multi-story parking device.

[0002]

2. Description of the Related Art In a mechanical multi-story parking lot, a pallet for carrying a car and moving up and down is used, and a guide rail for guiding the pallet up and down is installed.
A guide roller fitted to the guide rail is attached to the pallet.

[0003] The mechanical multi-story parking garage as described above is generally provided indoors, but in recent years, the number of cases where it is installed outdoors has increased.

[0004]

[Problems to be solved by the present invention] However, when installed outdoors, there are problems such as rust of the guide rollers, noise during running of the guide rollers, and short life of the guide rollers due to internal grease flowing out due to rainwater intrusion. Can be considered.

Accordingly, an object of the present invention is to provide a guide roller for a multi-story parking pallet which solves these problems.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to an inner ring, an outer ring, a rolling element interposed between the two wheels, and fitted to a guide rail installed in a multi-story parking device. In a guide roller consisting of a seal member mounted on the inner surface of the outer ring on both sides of the rolling element, the inner ring is subjected to rust prevention treatment, a vibration absorbing layer is formed on the outer surface of the outer ring, and A seal cover for covering the outer surface of the seal member is provided, and a space between the inner ring and the outer ring is filled with a solid lubricating composition comprising a mixture of ultra- high molecular weight polyolefin and lubricating grease.

[0007]

[Function] The above guide roller is mounted on a pallet,
It is used by fitting on a three-dimensional guide rail to guide the pallet up and down.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The guide roller of the embodiment shown in FIG. 1 is basically composed of a deep groove ball bearing composed of an inner ring 1, an outer ring 2, a steel ball 3 interposed in the raceway of both, and a retainer 4 of the steel ball 3. On both sides of the retainer 4, a seal plate 5 made of an iron plate is mounted on the inner diameter surface of the outer ring 2, and the inner diameter edge of the seal plate 5 faces the groove 6 formed on the outer diameter surface of the inner ring 1, and the labyrinth Constitutes a seal.

The outer surface of the inner ring 1 is subjected to a black dyeing treatment 15 as a rust preventive treatment. Further, a vibration absorbing layer 7 is formed on the outer surface and both end surfaces of the outer ring 2. This vibration absorbing layer 7
Is made of a synthetic resin such as polyamide or polyacetal, or urethane rubber.

The above-mentioned vibration absorbing layer 7 is formed in the middle of both end surfaces of the outer ring 2, and a plastic seal cover 8 is integrally formed with the vibration absorbing layer 7 on the inner surface of the end of the both end surfaces. The inner peripheral edge of the seal cover 8 is formed so as to approach the inner ring 1 to prevent the seal plate 5 from directly coming into contact with rainwater or the like, thereby preventing the seal plate 5 from rusting.

As in the embodiment shown in FIG. 2, the seal cover 8 'may be attached to the inner peripheral surface of the vibration absorbing layer 7 and the end surface of the outer ring 2 by press-fitting.

Further, as in the other embodiment shown in FIG.
The vibration absorbing layer 7 is formed so as to extend to the outer surface of the seal plate 5,
The seal covers 8, 8 'may be used instead.

In each of the above embodiments, the inner ring 1 and the outer ring 2
The so-called plastic grease 9 is filled in the space between the first and second seal plates 5. The details of the plastic grease 9 are as follows.

That is, the average molecular weight is about 1 × 10 ^{6 to} 5 × 10
After filling a mixture of 95 to 1 wt% of ultrahigh molecular weight polyethylene of No. ⁶ and 5 to 99 wt% of lubricating grease having a dropping point higher than the gelation temperature of the ultrahigh molecular weight polyethylene into the predetermined space, The high molecular weight polyethylene is heated and baked at a temperature equal to or higher than the gelation temperature, and then cooled and solidified.

As another example of a plastic grease, lubricating grease having a drop point higher than the gel point of an ultra-high molecular weight polyolefin having an average molecular weight of about 1 × 10 ^{6 to} 5 × 10 ⁶ has a particle size of 1 to 100 μm 95-1 wt% of the ultrahigh molecular weight polyolefin powder described above may be mixed and dispersed and maintained at a temperature equal to or higher than the gel point.

In any of the above cases, an additive for suppressing oil bleeding such as solid wax may be added.

The guide roller of the embodiment is as described above, and as shown in FIG. 4, a support shaft 12 fixed to brackets 11 at four corners of a pallet 10 of a mechanical multi-story parking lot.
The pallet 10 is guided by attaching the guide rollers 13 to the tips of the pallets and fitting the guide rollers 13 to the guide rails 14.

In the above embodiment, the guide roller 13 is used.
The vibration absorbing layer 7 is formed directly on the outer ring 2 of the outer ring 2.
The vibration absorbing layer 7 may be formed on an annular member fitted on the outer periphery of the device.

[0019]

[Effects of the Invention] As described above, the guide roller of the multi-story parking pallet of the present invention is provided with a rust-proof treatment on the inner ring, a vibration absorbing layer formed on the outer ring, and a seal cover. Rust prevention of the outer ring and the seal member can be achieved. Further, by forming the vibration absorbing layer on the outer ring, it is possible to reduce the sound when the pallet is raised and lowered.
In addition, the use of plastic grease prevents grease from flowing out, and both the plastic grease and the sealing member improve the sealing effect. Even when used in a multi-story parking lot installed outdoors, rust prevention and lubrication are ensured. Thus, the life of the guide roller can be extended.
