Abstract
The utility model relates to an upper bearing technology of a guide device of a rod rolling mill and a wire rolling mill, particularly relates to a structure for solving a guide bearing. The utility model discloses a guide bearing of a rod and wire rolling mill, which comprises an outer ring and an inner ring. The utility model is characterized in that the bearing is a double-row angular contact ball bearing; the center of the outer diameter of the outer ring of the bearing is provided with a circular arc-shaped roller groove; the outer ring of the bearing is simultaneously provided with a guide roller. The utility model replaces the existing a guide pulley which is composed of a roller and two sets of radial ball bearings. Due to the adoption of the combined integration of the roller and the outer ring of the bearing, the installing space of the bearing is enlarged, the dimension of a steel ball of a bearing is enlarged and the rated load of the bearing is increased. Because the double-row angular contact ball bearing replaces single-row radial ball bearings on both ends of the existing roller, the axial load capability of the bearing is improved, and the capability of anti-overturn force moment of the bearing is improved. The axial play of the bearing is effectively controlled, and the rigidity and the strength of the bearing are improved.
Description
Technical field
The utility model relates to the technology of bearing, is used in particular for the guide device upper block structure of bar mill and wire mill.
Background technique
Bar mill and wire mill in the operation of rolling, the guide wheel that relies on guide device to rolling rolled piece help and make it by setting motion.The guide wheel of guide device directly contacts with rolled piece in the course of the work, and its working environment is extremely abominable, bear physics and chemical actions such as high temperature, impact, friction, corrosion.The guide wheel of guide device exists the weak point in working life at present, changes frequently, influences problems such as manufacturing efficiency.Existing guide wheel is by roller and be installed in the omoplate hole, roller two ends single-row radial ball bearing and form, and bearing structure is for being with the deep groove ball bearing of single face dust cover, and there is oil-air lubrication the inboard.Because the inner installing space restriction of roller makes and selects for use two cover single-row radial ball bearing bearing capacitys of ting model low, fragile.On the other hand, the axial internal clearance of radial ball bearing is excessive, and the axial internal clearance size of assembling back guide wheel is wayward.Axial internal clearance is too big, is just changed after using the extremely short time; Axial internal clearance is too small, very easily damages because of radial internal clearance is littler.
Summary of the invention
Have deficiency for overcoming prior art, solve and lead the structure of a bearing, the utility model provides bar wire rod rolling mill to lead a bearing, substitutes the existing guide wheel of being made up of roller and two cover radial ball bearings.It can improve the bearing load ability effectively, improves bearing antidumping moment capacity.
The utility model is to realize by following technological scheme, it comprises outer ring, inner ring, its structure outline is that this bearing is a double-row angular contact bal bearing, and the external diameter central authorities of bearing outer ring are provided with a circular arc type roller groove, and bearing outer ring is the roller of guide wheel simultaneously.
The inner ring central authorities of above-mentioned double-row angular contact bal bearing are provided with an oil gas through hole.
The utility model is owing to adopt roller and bearing outer ring integrator, and the Bearing Installation space increases, and can increase the bearing steel ball size, has increased the bearing rated load.Substituted existing roller two ends single-row radial ball bearing with a double-row angular contact bal bearing, improved bearing shaft, improved bearing antidumping moment capacity to load capacity.The bearing axial internal clearance be can control effectively, bearing rigidity and intensity strengthened.
Description of drawings
Below with reference to drawings and Examples the utility model is further described.
Accompanying drawing is the utility model structural representation.
Embodiment
In the accompanying drawing, double-row angular contact bal bearing outer ring 1, steel ball 2, retainer 3, double-row angular contact bal bearing inner ring 4, axle 5, the shaft shoulder 6, oil gas through hole 7, seal ring 8, circular arc type roller groove 9.This bar wire rod rolling mill is led a bearing and is substituted the existing guide wheel of being made up of roller and two cover radial ball bearings.Circular arc type roller groove 9 of external diameter central authorities processing of this double-row angular contact bal bearing outer ring 1 makes bearing outer ring 1 also make the guide wheel roller simultaneously and uses.Roller and the bearing outer ring 1 rear bearing installing space that is integrated increases, and the size of steel ball 2 can strengthen, and has increased the bearing rated load.Owing to use double-row angular contact bal bearing, can improve bearing shaft to load capacity, improve bearing antidumping moment capacity, can improve bearing axial internal clearance and rigidity.The central authorities of double-row angular contact bal bearing inner ring 4 process an oil gas through hole 7 and communicate with hole on the axle 5, so that lubricating bearings.Bearing inner and outer ring 4,1 and rolling element steel ball 2 adopt high temperature resistant steel, to increase bearing integral intensity.Retainer 3 materials adopt plastics.Seal ring 8 seals.
