Abstract
The utility model relates to a roller support structure in a cold bed double-wheel box, comprising a support axle fixed and mounted on a double-wheel box, a bearing for supporting the roller and arranged on two ends of the support axle, characterized in that: the bearing is cylindrical roller bearing, a flow hole for lubricating the cylindrical roller bearing is arranged on the support axle and an oil filler is arranged on one end of the support axle. The cylindrical roller bearing is used to increase the radial and axial bearing force, therefore the service life of the double-wheel box is increased, the flow hole is arranged on the support axle, the lubricant oil is sent into the cavity between the roller and the support axle by the oil filler at the axle end and the bearings at two sides are lubricated, furthermore the service life of the bearing is increased, the rolling friction between the roller and an eccentric wheel is ensured, thus the movable beam is kept in phase to ensure the quality of the product.
Description
Technical field
The utility model relates to the two-wheel case that is used for fixing trave lling girder in the cold bed, particularly the idler wheel support structure in the two-wheel case.
Background technology
At present, bar is cooled off and the cold bed sheared comprises built-in beam and array trave lling girder, trave lling girder is fixedly installed on the two-wheel case, the two-wheel case is made of two-wheel casing and two roller set that are erected on the two-wheel casing, wherein roller set comprises the back shaft that is installed on the two-wheel casing, be installed in the deep groove ball bearing of back shaft both sides, be supported on the roller on the bearing.Above-mentioned two-wheel case is supported on the eccentric wheel structure by two rollers, by rotating eccentric wheel, just can realize the reciprocating motion of trave lling girder.Deep groove ball bearing in use appears in the two-wheel case to be destroyed, and makes the rolling friction between roller and the eccentric wheel become sliding friction, causes the motion of trave lling girder asynchronous, and bar is bent, and product quality does not reach requirement.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, improve two-wheel case service life, guarantee the idler wheel support structure in the cold bed two-wheel case of product quality.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Idler wheel support structure in a kind of cold bed two-wheel case, comprise the back shaft that is fixedly mounted on the two-wheel casing, be arranged on the bearing that the back shaft two ends are used for support roller, it is characterized in that: described bearing is a cylinder roller bearing, described back shaft is provided with the flowing hole that cylinder roller bearing is lubricated, and an end of back shaft is provided with oil filler.
Advantage and the good effect that the utlity model has are:
Adopt cylinder roller bearing, increased radial and axial bearing capacity, thereby improved the service life of two-wheel case, on back shaft, established flowing hole, by the oil filler of axle head, lubricating oil can be sent into the cavity between roller and the back shaft, bearing to both sides is lubricated, and has further improved the service life of bearing, guarantees the rolling friction between roller and the eccentric wheel, trave lling girder is kept synchronously, thereby guarantee the quality of product.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, two-wheel casing; 2, back shaft; 3, roller; 4, cylinder roller bearing; 5, flowing hole; 6, oil filler.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, idler wheel support structure in a kind of cold bed two-wheel case, comprise the back shaft 2 that is fixedly mounted on the two-wheel casing 1, be arranged on the bearing 4 that the back shaft two ends are used for support roller 3, described bearing is a cylinder roller bearing, described back shaft is provided with the flowing hole 5 that cylinder roller bearing is lubricated, one end of back shaft is provided with oil filler 6, particularly, flowing hole 5 comprise along the axial blind hole of back shaft part and with its perforation along back shaft throughhole portions radially, above-mentioned radial direction through hole is arranged between the two bearings, by to the oil filler oiling, lubricating oil just can enter the cavity between back shaft and the roller along above-mentioned flowing hole, and two side bearings are lubricated.
