Abstract
The utility model discloses an eccentric shaft for a side gauge device, which comprises an eccentric shaft body. A needle roller bearing is sleeved on the eccentric shaft body, and the inner diameter of the needle roller bearing is the same as the outer diameter of the eccentric shaft body. The eccentric shaft adopts the needle roller bearing with an outer diameter similar to that of a copper sleeve, and lubrication of the needle roller bearing is far higher than that of the copper, so that friction force is decreased, the service life of the eccentric shaft is prolonged greatly, and precision of a corresponding pull gauge is also improved. In normal conditions, the eccentric shaft can be continuously used for more than half a year and can be operated for a year under a fine lubrication condition, so that maintenance cost and complicated assembly and disassembly workload are reduced.
Description
Technical field
The utility model relates to the side mark device in the intaglio printing system, particularly a kind of eccentric shaft that is used for the side mark device.
Background technology
The side mark device includes an eccentric shaft assembly, and is as shown in Figure 1, and at work, eccentric shaft is that swing moves, and the angle of its swing is spent between 45 degree 30, for need of work, on eccentric shaft, is with a copper sheathing 2.Find that in use both are easy to generate wearing and tearing copper sheathing 2 and eccentric shaft 1, trace it to its cause; Be because copper sheathing is different materials with eccentric shaft; Eccentric shaft is that iron is processed, and eccentric shaft and copper sheathing coefficient of friction are bigger, and copper sheathing internal diameter and eccentric shaft external diameter are difficult to accurate coupling.
Under the normal condition, continuous operation need be changed copper sheathing once week, need pull down whole side mark device during replacing; Change the copper sheathing whole side mark that must disintegrate, so dismounting is got up very inconvenient, consuming time more; Maintenance load is also very big, has also reduced the side mark precision.
The utility model content
The utility model has overcome the deficiency that exists in the above-mentioned prior art, provides a kind of degree of wear little, does not need frequent renewal part, has improved the eccentric shaft of side mark precision.
The technical scheme of the utility model is achieved in that
A kind of eccentric shaft that is used for the side mark device comprises the eccentric shaft body, on the eccentric shaft body, is with a needle bearing, and the internal diameter of described needle bearing is identical with the external diameter of eccentric shaft body.
Adopted the beneficial effect of the utility model of technique scheme to be:
The utility model adopts the needle bearing close with the copper sheathing external diameter; The internal diameter of needle bearing is identical with the external diameter of eccentric shaft body, and the degree of lubrication of needle bearing is much larger than copper sheathing, so reduced frictional force; Prolonged service life greatly, draws the rule precision also to improve accordingly; Under the normal condition, can use continuously more than half a year, under the good condition of lubricating condition, work 1 year also no problem, thereby reduced maintenance cost and loaded down with trivial details disassemble and assemble work amount.
Description of drawings
Fig. 1 is the fractionation structural representation of eccentric shaft and copper sheathing in the prior art;
Fig. 2 is the fractionation structural representation of the utility model eccentric shaft and needle bearing.
The specific embodiment
The specific embodiment of the utility model is following:
Embodiment: a kind of eccentric shaft that is used for the side mark device, as shown in Figure 2, comprise eccentric shaft body 1, on eccentric shaft body 1, be with a needle bearing 3, the internal diameter of described needle bearing 3 is identical with the external diameter of eccentric shaft body.
Claims (1)
1. an eccentric shaft that is used for the side mark device comprises the eccentric shaft body, it is characterized in that: on the eccentric shaft body, be with a needle bearing, the internal diameter of described needle bearing is identical with the external diameter of eccentric shaft body.
