Abstract
The utility model relates to the field of flux-cored wire forming manufacturing equipment, in particular to a composite structure of a roller shaft, a bearing and a bearing lock sleeve for a solder wire rolling mill. The composite structure comprises the roller shaft and the bearing, wherein the bearing is sleeved on the roller shaft. The composite structure of the roller shaft, the bearing and the bearing lock sleeve for the solder wire rolling mill is characterized by further comprising the bearing lock sleeve. A shaft section of the roller shaft is cone-shaped, wherein a roller is arranged on the cone-shaped shaft section of the roller shaft. The bearing lock sleeve is sleeved on the roller shaft and located at the back portion of the bearing. At least a key groove is formed in the surface, contacting with the bearing lock sleeve, of the roller shaft. A protrusion point is arranged on the surface of the inner wall of the tail end of the bearing lock sleeve. The protrusion point is located at the tail end in the key groove of the surface of the roller shaft. The bearing lock sleeve is divided into a supporting section which is contacted with the back portion of the bearing and a locking section which acts with the key groove of the roller shaft. The protrusion point is located on the locking section, and the wall thickness of the locking section is smaller than that of the supporting section. By the adoption of the structure, the installation accuracy of the roller shaft is improved, the requirement of maintaining is reduced, the roller is convenient to install, and the installation quality is guaranteed.
Description
Technical field
The utility model relates to flux-cored wire shaping manufacturing equipment field, and the rolling axle that relates in particular to the welding wire milling train reaches bearing matching used with it, bearing lock tube.
Background technology
The rolling axle that tradition welding wire milling train is used when mounted, adopt round nut to cooperate the mode of stop washer to play the axial locking effect of bearing, yet, this kind method in use, reasons such as vibrations owing to body, stop washer can lose efficacy gradually, cause round nut to get loose, forfeiture is to the effect of bearing axial locking, simultaneously, tradition welding wire mill rolls wheel bearing is two inner rings, the double row tapered roller axis of a cylinder holds, though it can bear heavy load, shortcoming is the installation exercise complexity, the installation quality instability, need simultaneously regularly to inject grease with lubricate, thereby cause the gage of wire of mill milling to be difficult to stablize.
Summary of the invention
The purpose of this utility model is, combination and the structure of a kind of rolling axle and bearing, bearing lock tube is provided, and it can guarantee the smooth operation of mill rolls wheel shaft, improves the installation accuracy of bearing, and is convenient to upkeep operation.
In order to achieve the above object, the utility model is achieved in that
The combining structure of a kind of welding wire milling train usefulness rolling axle and bearing, bearing lock tube, it comprises rolling axle, bearing, bearing holder (housing, cover) is located on the rolling axle, also comprises the bearing lock tube; The shaft part of described rolling axle installation running roller is tapered; Described bearing lock tube is placed on the rolling axle and is positioned at the rear of bearing, and the surface that rolling axle contacts with the bearing lock tube offers at least one keyway, and the tail end inner wall surface of bearing lock tube is provided with salient point, and described salient point is positioned at the end of the keyway on rolling axle surface; The bearing lock tube be divided into the supporting section that contacts with the bearing rear and with the locking section of rolling axle keyway effect, salient point is positioned at the locking section, the wall thickness of locking section is less than the wall thickness of supporting section.
The combining structure of described welding wire milling train usefulness rolling axle and bearing, bearing lock tube, the wall thickness of bearing lock tube locking section is 0.5mm ~ 5mm.
The combining structure of described welding wire milling train usefulness rolling axle and bearing, bearing lock tube, the case hardness of rolling axle is HRC 40 ~ 45.
The combining structure of described welding wire milling train usefulness rolling axle and bearing, bearing lock tube, bearing is double-row angular contact ball bearing.
The tapering that the combining structure of described welding wire milling train usefulness rolling axle and bearing, bearing lock tube, rolling axle are used for the taper shaft part of installation running roller is 15 degree.
The utility model adopts said structure, it selects double-row angular contact ball bearing for use, thereby improve the installation accuracy of rolling axle, and reducing maintenance needs, and simultaneously, adopts the bearing lock tube, avoided moving axially of bearing, the installation juncture of axis body and running roller changes the tapering contact-making surface into, has made things convenient for the installation of running roller, guarantees installation quality.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below further specify the utility model by specific embodiment.
As shown in Figure 1, the combining structure of a kind of welding wire milling train usefulness rolling axle and bearing, bearing lock tube, it comprises rolling axle 1, bearing 5, bearing 5 is sheathed on the rolling axle 1, also comprises bearing lock tube 6; The shaft part 2 that described rolling axle 1 is installed running roller 5 is tapered; Described bearing lock tube 6 is placed on the rolling axle 1 and is positioned at the rear of bearing 5, the surface that rolling axle 1 contacts with bearing lock tube 6 offers at least one keyway 8, the tail end inner wall surface of bearing lock tube 6 is provided with salient point 7, and described salient point 7 is positioned at the end of the keyway 7 on rolling axle 1 surface; Bearing lock tube 6 is divided into the supporting section 62 that contacts with bearing 5 rears and the locking section 61 that acts on rolling axle 1 keyway 7, and salient point 7 is positioned at locking section 61, and the wall thickness of locking section 61 is less than the wall thickness of supporting section 62.
The combining structure of described welding wire milling train usefulness rolling axle and bearing, bearing lock tube, the wall thickness that 6 lockings of bearing lock tube are 61 sections is 0.5mm ~ 5mm.
The combining structure of described welding wire milling train usefulness rolling axle and bearing, bearing lock tube, the case hardness of rolling axle 1 is HRC 40 ~ 45.
The combining structure of described welding wire milling train usefulness rolling axle and bearing, bearing lock tube, bearing 5 is double-row angular contact ball bearing.
The tapering that the combining structure of described welding wire milling train usefulness rolling axle and bearing, bearing lock tube, rolling axle 1 are used for the taper shaft part 2 of installation running roller is 15 degree.
The utility model adopts said structure, it selects double-row angular contact ball bearing for use, thereby improve the installation accuracy of rolling axle, and reduce and safeguard needs, simultaneously, adopt the bearing lock tube, avoided moving axially of bearing, the installation juncture of axis body and running roller changes the tapering contact-making surface into, has made things convenient for the installation of running roller, guarantee installation quality, thereby improve the diameter precision and stability of mill milling welding wire.
