Abstract
The utility model relates to a bidirectional thrust tapered roller bearing used in the pressure roller of the roller mill, comprising base rings (1), a shaft ring (2), rollers(3), semi-holders (4), semi-holders (5), an outer isolating ring (6) and pins (7). When the bidirectional thrust tapered roller bearing is assembled, firstly the rollers (3) are installed between the semi-holder (4) and the semi-holder (5), the pins (7) realizes the connection relation among the rollers (3), the semi-holder (4) and the semi-holder (5); the integration assembled by the rollers (3), the semi-holder (4) and the semi-holder (5) is installed on one base ring (1) of the bearing, each base ring (1) is provided with roller grooves to embed the rollers, then the bearing shaft ring (2) is arranged between the same two integrations assembled by the rollers (3), the semi-holder (4) and the semi-holder (5); the outer isolating ring (6) is arranged between the two base rings(1); and at last the other base ring is assembled. The bidirectional thrust tapered roller bearing can automatically regulate the radial moving position of the shaft.
Description
Technical field:
The utility model relates to the part or the annex of bearing, a kind of novel bidirectional thrust tapered roller bearing.
Background technique:
In iron and steel enterprise produces, has the two end supports bearing on the pressure roller of the milling train in the metallurgical equipment, owing to tend to exist small offset between the axle center of back shaft and the seat ring, under the situation of running up, this small off-centre will cause the heavy wear of bearing, reduced the life-span of bearing,, also strengthened the economic burden of enterprise for production brings inconvenience.
Summary of the invention:
In order to overcome the shortcoming that exists in the prior art, the purpose of this utility model provides a kind of novel bidirectional thrust tapered roller bearing, milling train in the solution metallurgical equipment is under the situation of running up, the heavy wear of bearing, reduce the problem in working life of bearing, guaranteed the normal operation of metallurgical equipment, enhanced productivity.
In order to realize the foregoing invention purpose, the utility model by the following technical solutions:
Described novel bidirectional thrust tapered roller bearing, it is by seat ring, blowout patche, roller, half retainer, outer ring spacer is formed; The raceway groove that embeds for roller is arranged on the inner ring, and roller means is fixedlyed connected roller by pin in the middle of the two halves retainer with half retainer, and the integral installation after the assembling of two halves retainer is on a seat ring of bearing; The bearing blowout patche places between the two halves retainer; The outer ring spacer device is between two seat rings.
Owing to adopted technological scheme as mentioned above, the utlity model has following superiority:
In the utility model, because roller is embedded on the groove of seat ring, retainer and outer ring spacer have rational gap, so its blowout patche can be realized certain moving radially.In the process of actual processing accessories, bearing can adjustable axle moves radially the position, thereby has eliminated existing small offset between axle and the seat ring, and the wearing and tearing that alleviated bearing have improved production efficiency of products, have reduced cost of production.
This purpose is finished and is embodied as and uses producer to save a large amount of foreign exchange funds, has produced excellent economic and social benefit in national like product production; The production domesticization of finishing to similar bearing of this project simultaneously provides the experience that designs and process.
Description of drawings:
Fig. 1 is the overall structure schematic representation of novel bidirectional thrust tapered roller bearing.
As shown in fig. 1: 1-seat ring, 2-blowout patche, 3-roller, 4-half retainer, 5-half retainer, 6-outer ring spacer, 7-pin.
Embodiment:
As shown in fig. 1: described novel bidirectional thrust tapered roller bearing, it has seat ring (1), blowout patche (2), roller (3), half retainer (4), half retainer (5), outer ring spacer (6) and pin (7).During assembling, earlier that roller (3) device is middle at half retainer (4) and half retainer (5), realize its three's annexation by pin (7); Roller (3), the integral installation that half retainer (4) and half retainer (5) are dressed up have the raceway groove that embeds for roller on the seat ring (1) on a seat ring (1) of bearing; Again bearing blowout patche (2) is placed on by roller (3), between two identical integral body that half retainer (4) and half retainer (5) are dressed up; Outer ring spacer (6) is installed between two seat rings (1); At last the another one seat ring is loaded onto, just realized the assembling of bearing.
Claims (1)
1, the novel bidirectional thrust tapered roller bearing on a kind of milling train pressure roller, it is by seat ring (1), blowout patche (2), roller (3), half retainer (4) and half retainer (5) are formed; The raceway groove that embeds for roller is arranged on the inner ring, and roller means is fixedlyed connected roller by pin in the middle of the two halves retainer with half retainer, and the two halves retainer is assembled into the back integral installation on a seat ring (1) of bearing; Bearing blowout patche (2) places between two halves retainer (4) and (5); It is characterized in that: described tapered roller bearing is provided with an outer ring spacer (6) between two seat rings (1).
