Abstract
The invention relates to a double-row tapered roller bearing with a fixed guide device, which is mainly used for the roller of the rolling mill in the steel industry. The bearing comprises set screws, guide outer ring spacers, retaining frames, inner rings, rollers and outer rings. The set screws are fixed on the guide outer ring spacers, two grooves are respectively arranged on the outer rings along the radial circumference of each, the set screws are arranged deep into the grooves on the outer rings, the outer rings are respectively and fixedly connected with the guide outer ring spacers; the guide clearance of each outer ring is controlled within 0.3-0.6mm in the radial direction by the outer ring spacer, thereby unbalanced load caused by excessive mutual dislocation of the outer rings of the bearing is avoided when the outer rings are installed. The moving ranges of internal components are controlled through the outer rings by guide outer ring spacers. During the installation of the bearing, the size of the guide outer ring spacer is determined according to the external diameter of the bearing outer ring. The invention meets the requirement for axial load well, and overcomes the problems that the bearing is often loosened in structure and inconvenient for installation, and unbalanced load may occur when the bearing is stressed with the axial force because the guide outer ring spacers guide the outer rings, and are integrated with the outer ring through the screws.
Description
Technical field
The present invention relates to a kind of double-row conical bearing that fixed guide device is arranged that is mainly used on the steel industry rolling mill roll.
Background technique
Traditional bearing that is applied on the steel industry rolling mill roll is former thrust bearing, does not have fixed guide device, when demolition and maintenance, and the frequent sequence of sanqu songs within a particular musical mode, unbalance loading may take place when standing axial force in inconvenience during installation, influences bearing working life.
Summary of the invention
In order to overcome the often sequence of sanqu songs within a particular musical mode of bearing, problems such as unbalance loading may take place in inconvenience during installation when standing axial force, the invention provides a kind of double-row conical bearing that fixed guide device is arranged.
Technological scheme of the present invention is: the double-row conical bearing of fixed guide device is arranged, comprise retaining screw 1, guiding outer ring spacer 2, retainer 3, inner ring 4, roller 5 and outer ring 6.Retainer 3, inner ring 4 and the roller 5 common inner assemblies of forming, inner assembly is connected with outer ring 6, simultaneously, retaining screw 1 is fixed on the guiding outer ring spacer 2, and 6 upper edge radial circumferences are provided with groove in the outer ring, and retaining screw 1 is deep in the groove on the outer ring 6, fixedlyed connected with guiding outer ring spacer 2 in outer ring 6, upwards guide clearance is in 0.3～0.6mm for 6 footpaths, guiding outer ring spacer 2 control outer rings, and mutual dislocation is excessive when preventing bearing outer ring 6 installations, causes unbalance loading.Guiding outer ring spacer 2 is by the moving range of outer ring 6 control inner assemblies.
In the Bearing Installation process,, determine the size of guiding outer ring spacer according to the bearing outer ring external diameter.
The invention has the beneficial effects as follows: well satisfy the thrust load requirement, and guiding outer ring spacer guiding outer ring, and form one, inconvenience when having overcome the frequent sequence of sanqu songs within a particular musical mode of bearing, installation, problem such as unbalance loading may take place when standing axial force by screw and outer ring.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1. retaining screw, 2. guiding outer ring spacer, 3 retainers, 4. inner ring, 5 rollers, 6. outer ring.
Embodiment
The present invention will be further described in detail below in conjunction with accompanying drawing.
As shown in Figure 1, the double-row conical bearing of fixed guide device is arranged, comprise retaining screw 1, guiding outer ring spacer 2, retainer 3, inner ring 4, roller 5 and outer ring 6.Retaining screw 1 is fixed on the guiding outer ring spacer 2,6 upper edge radial circumferences are provided with groove in the outer ring, being deep in the groove on the outer ring 6 of retaining screw 1, fixedlyed connected with guiding outer ring spacer 2 in outer ring 6, guide 6 footpaths, outer ring spacer 2 control outer rings to make progress guide clearance in 0.5mm simultaneously, mutual dislocation is excessive when preventing bearing outer ring 6 installations, causes unbalance loading.Retainer 3, inner ring 4 and the roller 5 common inner assemblies of forming, inner assembly is connected with outer ring 6, and guiding outer ring spacer 2 is by the moving range of outer ring 6 control inner assemblies, totally two of retaining screws 1, one of each outer ring.
