Description

For the lower support roll of planisher

Technical field

The utility model relates to a kind of lower support roll for planisher.

Background technology

As shown in Figure 1, lower support roll for planisher of the prior art, comprise the supporting body of roll, be arranged at the roll shaft at described supporting body of roll two ends, be arranged at the bearing block matched with it at described roll shaft two ends, primitive axis bearing pressure-bearing surface is plane, for rigidity carrying, unfavorable to shaft strength distribution, large to bearing infringement, bearing is short for service life, and the cracked phenomenon of bearing outer ring is serious.

Summary of the invention

The purpose of this utility model is the deficiency overcoming above-mentioned technology, thus provides a kind of lower support roll for planisher, and the cracked phenomenon of bearing outer ring obviously reduces, and bearing life significantly increases.

The technical scheme that the utility model adopts is such: for the lower support roll of planisher, comprise the supporting body of roll, be arranged at the roll shaft at described supporting body of roll two ends, be arranged at the bearing block matched with it at described roll shaft two ends, the bottom of bearing block described in both sides is all fixedly installed semi arch plate, the arc surface of described semi arch plate down, the length direction of described semi arch plate and the axis parallel of the described supporting body of roll.

Further improvement: the bottom inside described bearing block offers some bolts hole, the upper end of described semi arch plate is connected by some bolts with described bearing block.

Further improvement: the arc surface of described semi arch plate is provided with some reticulate patterns.

Further improvement: be provided with some reinforcement gussets between described semi arch plate and described bearing block.

By adopting preceding solution, the beneficial effects of the utility model are: install one block of semi arch plate additional in bearing block bottom surface, thus make that bearing block is stressed can be regulated automatically, make bearing block uniform force, reduce the damage of bearing, reduce the cracked phenomenon of bearing outer ring, extend bearing service life.

Fig. 1 is prior art schematic diagram;

Fig. 2 is the utility model schematic diagram.

Wherein: 1, support the body of roll; 2, roll shaft; 3, bearing block; 4, semi arch plate.

Detailed description of the invention

The utility model is further illustrated below in conjunction with the drawings and specific embodiments.

As shown in Figure 2, the utility model discloses a kind of lower support roll for planisher, comprise the supporting body of roll 1, be arranged at the roll shaft 2 at the described supporting body of roll 1 two ends, be arranged at the bearing block 3 matched with it at described roll shaft 2 two ends, described in both sides, the bottom of bearing block 3 is all fixedly installed semi arch plate 4, the arc surface of described semi arch plate 4 down, the length direction of described semi arch plate 4 and the axis parallel of the described supporting body of roll 1.

Transformation process and principle: install one block of semi arch plate 4 additional in bearing block 3 bottom surface, thus make that bearing block 3 is stressed can be regulated automatically, make bearing block 3 uniform force, reduce the damage of bearing, reduce the cracked phenomenon of bearing outer ring, extends bearing service life.

Conveniently be connected and fixed, the bottom inside described bearing block 3 offers some bolts hole, and the upper end of described semi arch plate 4 is connected by some bolts with described bearing block 3.

The embodiment optimized in the present embodiment is, the arc surface of described semi arch plate 4 is provided with some reticulate patterns.

The embodiment optimized in the present embodiment is, is provided with some reinforcement gussets between described semi arch plate 4 and described bearing block 3.

More than show and describe general principle of the present utility model and principal character and advantage thereof; the technical staff of the industry should understand; the utility model is not restricted to the described embodiments; above-described embodiment just illustrates principle of the present utility model with description in explanation; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall within the scope of claimed the utility model, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
