Abstract
The utility model discloses a six-row roller (04) bearing which is used for a rolling mill and comprises six-row rollers (04), wherein each three-row rollers are one group, each group comprises an outer ring (01), an inner ring (02) and a retainer (06), two ends of the outer ring (01) are respectively provided with two flanges, three-row rollers (04) of each group are arranged side by side and limits position of axis direction via the flange, the retainer (06) is ring comb shape, gaps among comb bents forms pocket holes which are uniformly distributed on circle, the opening of the comb bent end is used for handing rollers (04), the opening end of the retainer (06) is provided with a ring groove, and a spring steel wire is arranged in the groove. The outer ring of the bearing is not increase a middle lip, thereby being convenient for abrasive machining and improving accuracy. The six-row roller bearing adopts comb shaped retainer whose one end is opened and locked with the spring steel wire, thereby lengthening rollers, the end faces of three-row rollers are arranged side by side and loaded in one retainer, thereby increasing bearing capacity and improving operating life of the bearing.
Description
Technical field
The utility model relates to a kind of bearing, more particularly, relates to a kind of bearing that is provided with six row cylinder rollers.
Background technique
The milling train of prior art adopts the comb shape retainer with four row cylindrical bearings, the outer state-owned centre rib of bearing, its complex structure, bearing capacity difference and installation inconvenience.
And the milling train of prior art is made of two foreign countries, two inner rings, two comb shape retainers and four-row cylindrical roller with bearing FCD type.Each outer state-owned two outer rib of this bearing, a centre rib, so foreign technology capability is poor, precision is not high, again owing to adopt the comb shape retainer, cylindrical roller is half of vertically the contact with retainer, therefore half of in addition easily countersunk head is unfavorable for the assembling of inner ring, especially when the reconditioning roll, need be with bearing inner race could load and unload roll, and this installation difficulty is bigger again after the reconditioning.
Summary of the invention
At the problems referred to above, the utility model provides a kind of roller bearing that is exclusively used on the milling equipment, and this type of bearing accuracy that its purpose is intended to solve prior art is not high, the unloading difficulty is installed, problem such as easy care not.
In order to achieve the above object, the utility model has been constructed a kind of six-row cylindrical roller bearing for rolling mill, comprises six-row cylindrical roller 04, and wherein every three-row cylindrical roller is one group.Every group comprises the foreign country that is positioned at the roller outside, the inner ring that is positioned at the roller inboard, and the retainer between foreign country and inner ring.The two ends of foreign country are respectively arranged with the flange that protrudes to the axle center; Every group three-row cylindrical roller is arranged side by side, and by above-mentioned flange limit axial position.Every group of retainer is annular pectination, forms uniform pocket hole on the circumference between broach, and the nose of comb opening is used to load and unload cylindrical roller; Above-mentioned opening end at retainer offers circular groove, is provided with Spring Steel Wire in the groove.
By technique scheme, bearing of the present utility model, its foreign country does not add centre rib, thereby is convenient to grinding, and has therefore improved precision.The change comb shape retainer that adopts is the retainer of an end opening with the Spring Steel Wire fore shaft, the cylindrical roller that extended, and the end face of three row rollers is arranged side by side, and is contained in the retainer, has increased bearing capacity, has improved the life-span that makes of bearing.

Embodiment
Shown in Fig. 1-6, six-row cylindrical roller bearing for rolling mill of the present utility model comprises six-row cylindrical roller 04, and wherein, every three-row cylindrical roller is one group.Every group comprises the foreign country 01 that is positioned at the roller outside, the inner ring 02 that is positioned at the roller inboard, and the retainer 06 between foreign country 01 and inner ring 02.
Among Fig. 1, the two ends of foreign country 01 are respectively arranged with the flange that protrudes to the axle center; Every group three-row cylindrical roller is side by side by putting, and by this flange limit axial position.
Referring to Fig. 5 and 6, every group of retainer 06 is annular pectination, forms uniform pocket hole on the circumference between broach, and the nose of comb opening is used to load and unload cylindrical roller.Offer circular groove at this opening end, be provided with Spring Steel Wire 19 (as shown in Figure 4) in the groove.
This bearing structure adopts two foreign 01, two inner ring 02 of no centre rib, retainer 06, Spring Steel Wire 19 and the along the circumferential direction uniform six-row cylindrical roller 04 of two end openings.In six-row cylindrical roller 04, the end face of per three row rollers 04 is against being contained in the retainer 06.Because the gap of having eliminated per three row rollers, the length of the bearing roller of same widths has increased, thereby has increased the area of contact with inside and outside state, has improved bearing capacity and working life.The retainer 06 of one end opening is packed into behind the cylindrical roller 04, is the opening locking of Spring Steel Wire 19 being put into retainer during end socket.
This bearing has been owing to adopted said structure, the problem of the easy countersunk head of roller when having solved this class bearing inconvenience assembling of prior art and maintenance, and therefore improved precision, increased the bearing capacity and the working life of bearing.The utility model is compared with the bearing of same size, and radially Cheng Zai dynamic load has improved 35%, improve 120 times working life, and the linear velocity of milling train can improve more than 60%, and the retainer course of working is simplified, convenient, easy row.
