Abstract
Disclosed is a combined hyperbolic roller bearing, comprising an inner casing, an outer casing and two end covers. The two end covers are respectively top pressed on two ring end faces at the two sides of the inner casing; the outer wall of the outer casing is in hyperbolic arc shape, the two side ends of the inner wall of the outer casing are respectively provided concavely with ring shaped grooves; sphere tracks and sealed grooves which are matched with each other are respectively arranged on the groove walls of the ring shaped grooves and the outer walls of the two end covers; steel beads are filled between the outer casing and the matched sphere track arranged on the two end covers; sealing rings is sandwiched between the sealed grooves. The utility model has the advantages of simple structure, convenient assembly and strong heavy load bearing capacity.
Description
The utility model relates to a kind of bearing, particularly relates to a kind of combined type hyperbola roller bearing that is used on the Spiral Steel Pipe machine.
The bearing that is used for all kinds of tube producer assembly covers at present mostly adopts roller bearing, roller bearing can be divided into single-row roller bearing and double-row roller bearing again, because single-row roller bearing does not guarantee axis of rotation and neutral position three's concentricity, add that roller is long, very mistake often occurs after dressing up cover, therefore replaced by Biserial cylindrical roller bearing gradually in recent years.Producing Biserial cylindrical roller bearing at present is that two retainers that a plurality of short columnar rollers are housed are set between inner ring and outer ring, on two retainers, be equiped with a plurality of cylindrical rollers, though this kind structure has been improved the flexibility and the crushing resistance of bearing rotation, more and more can not satisfy steel pipe equipment to overweight load and impact load ability and high-precision requirement.
The purpose of this utility model is to provide a kind of Location accuracy height, rotation flexibly at the problems referred to above, the combined type hyperbola roller bearing that the impact resistance load carrying capacity is strong.
The purpose of this utility model realizes by following technological scheme, that is:
Combined type hyperbola roller bearing comprises interior cover, overcoat and two end caps.The internal diameter of two end caps is identical with the internal diameter of interior cover, its external diameter is greater than the external diameter of interior cover, two end cap difference buckle closures are on the annular end face of interior cover both sides, and cover both sides annular end face partly formed annular rib in two end caps leant out, the outer wall of overcoat is the hyperbola arc, the both side ends of inner wall surface thereof is concaved with the annular groove that can hold into the end cap outer rim respectively, be respectively equipped with spherical track and sealed groove on the cell wall of annular groove, the inboard of two end cap outer wall also be concaved with respectively with outside two spherical track putting be the corresponding spherical track of miter angle.On two end cap outer wall with outside two sealed groove corresponding sections putting also be concaved with sealed groove respectively.Respectively filled steel ball between the spherical track on two spherical track that put and two end caps outward.Sealed groove on two end caps and put outward between corresponding two sealed grooves and be folded with seal ring has respectively been filled two line column rollers in by interior cover and overcoat and two cavitys that end cap surrounded.
Be concaved with an annular oil groove on the madial wall of cover in above-mentioned, the bottom land of annular oil groove is provided with the oil hole that runs through sidewall of the inside race.
Above-mentioned being installed in by installing a spacer ring between the two row rollers in interior cover, overcoat and two cavitys that end cap surrounded.
The utlity model has simple in structure, easy to assembly, rotation flexibly, bear heavy load and the impact resistance load carrying capacity is strong, advantages such as long service life.
Fig. 1 is a kind of embodiment's of the utility model a structural representation, and Fig. 2 is the another embodiment's of the utility model a structural representation.The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment one
Combined type hyperbola roller bearing, cover 1, overcoat 2 and two end caps 3 in comprising.The center of two end caps 3 has the axis hole identical with the internal diameter of interior cover 1, the external diameter of two end caps 3 is greater than the external diameter of interior cover 1, two end cap 3 difference roof pressures are on the annular end face of interior cover 1 both sides, and two end caps 3 lean out the interior part formation rib that overlaps the both sides annular end face.The outer wall of overcoat 2 is the hyperbola arc, and the both side ends of inner wall surface thereof is provided with the annular groove 5 that can hold into end cap 3 outer rims respectively, establishes spherical track 6 and sealed groove 7 on the cell wall of annular groove 5 respectively.The inboard corner of two end caps 3 is concaved with spherical track 9 respectively, it is corresponding that spherical track 9 and spherical track 6 are miter angle, and filled steel ball 10 therebetween, on the outer wall of two end caps 3, also be concaved with sealed groove 8 respectively with sealed groove 7 corresponding sections, accompany seal ring 11 respectively between corresponding two sealed grooves 7 on sealed groove 8 on two end caps 3 and the overcoat 2, in the cavity that is surrounded by interior cover 1 and overcoat 2 and two end caps 3, fill two line column rollers 4, on the inwall of interior cover 1, be concaved with an annular oil groove 13, on the bottom land of annular oil groove 13, be drilled with one run through in the cover 1 sidewall oil hole 12.
Embodiment two
Embodiment two and embodiment's one difference is to be equiped with a spacer ring 14 between two line column rollers 13.
