Abstract

The utility model belongs to the manufacturing field of printing machines, used for a support of an inking roller of a pressing machine. A sliding bearing in the prior art are replaced by a cylindrical roller bearing provided with a retainer, and the utility model is a bearing combined by a double-row single outer ring (two rows of cylindrical rollers) composed of an outer ring (1), an inner ring (2), cylindrical rollers (3) and a retainer (4) and can also be combined by one or two inner and outer rings. The rotation speed and operating precision of the inking roller of the printing machine can be increased, the inking of printed products is uniform, the operation is smooth, and the work efficiency is increased.

Description

Printing press string inking roller supports with rolling

The utility model belongs to printing machinery and makes the field, is used for the supporting of printing press string inking roller, and it is the rotational speed height not only, and has the effect of sliding bearing, has increased the distance of the axially reciprocating of string inking roller.

Sliding bearing is adopted in the supporting of printing press string inking roller mostly in existing technology, and is sliding friction between sliding bearing and the string inking roller axle, and surface friction drag is big, and efficient is low, and starting torque is big during startup.In the motion, rotating speed requires can not be too high, and running accuracy is lower, and it is easy to wear in addition, and the life-span is low, and Installation and Debugging are also difficult.

The purpose of this utility model is to overcome above-mentioned shortcoming, changing sliding bearing and be the cylinder that has retainer rolls and gives bearing, the change sliding friction is rolling friction, adopt the combination of the single outer ring of biserial (two row's cylinders roll and give) and one or two inner ring, perhaps adopt the combination of two outer rings of biserial (two row's cylinders roll and give) and an inner ring, can also adopt two cover single-row (cylinder rolls and gives) bearings to combine side by side, to improve the bearing capacity of bearing.In order to increase the distance of string inking roller axially reciprocating, roll with common cylinder and give the bearing ratio, strengthened inner ring.

Technology implementation scheme of the present utility model (Fig. 1,2,3,4 shows):

A kind of printing press string inking roller supports with rolling, its structure by outer ring 1, inner ring 2, cylinder roll give 3 and retainer 4 form, it is characterized in that it is a rolling bearing.

Described printing press string inking roller supports with rolling, it is characterized in that by two outer rings 1, two inner ring 2 and cylinder roll give 3, retainer 4, rivet 5 and retainer lid 6 rolling bearings of forming (Fig. 1 shows).

Described printing press string inking roller supports with rolling, it is characterized in that by single outer ring 1, two inner ring 2 and cylinder roll give 3, rolling bearing (Fig. 2 shows) that retainer 4 is formed.

Described printing press string inking roller supports with rolling, it is characterized in that by single outer ring 1, single inner ring 2 and cylinder roll give 3, rolling bearing (Fig. 3 shows) that retainer 4 is formed.

Described printing press string inking roller supports with rolling, it is characterized in that by two outer rings 1, single inner ring 2 and cylinder roll give 3, retainer 4, rivet 5 and retainer lid 6 rolling bearings of forming (Fig. 4 shows).

The utility model embodiment (Fig. 3 shows) it by single outer ring 1, single inner ring 2 and cylinder roll give 3, rolling bearing that retainer 4 is formed, when the running of supporting printing machine string inking roller, be rolling friction, friction factor is little, can improve the rotating speed of printing press string inking roller and running accuracy, running is steady.According to the job requirement of string inking roller needs transverse reciprocating motion, adopted the lateral length of long inner ring 2 again, thereby increased the distance of printing press string inking roller transverse reciprocating motion, made that China ink has evenly improved the quality of bearing capacity and printedmatter on the printedmatter.

Facts have proved that adopt this printing press string inking roller to support with rolling, not only running steadily reduced noise, and the quality of efficient and printedmatter improves greatly.
