Abstract
The utility model relates to a roller. Cracked technical problem easily takes place for solving present roller spindle nose, the utility model provides an anti stress endurance roller, including outer barrel, the both ends of barrel are equipped with the end plate outside, spindle nose and support rib plate, its characterized in that: the spindle nose on the interference connect an axle sleeve, this axle sleeve adopts the assembly of heat expansion method, the support rib plate of the internal portion of end plate and urceolus respectively with the internal surface and the axle sleeve welded fastening of outer barrel. The beneficial effects of the utility model are that: the counter shaft capitiform becomes stress concentration in the time of can preventing to weld through the increase axle sleeve, can not lead to the fact destruction to the spindle nose material simultaneously, can effectively increase the life of roller.
Description
Technical field
The utility model relates to a kind of roller, specifically refers to a kind of resistance to stress endurance roller.
Background technique
Steel roller is mainly used in the machine driven system in manufacturing field, such as nearly all manufacturing field such as mine, papermaking, iron and steel, cement, building, food processing.Its performance requirement has certain loading force, coaxality, static and dynamic equilibrium degree etc.The structure of current steel roller mainly comprises outer cylinder body, and be provided with end plate at the two ends of outer cylinder body, spindle nose, end plate welds with spindle nose, is provided with bearing rib in the inside of end plate, and the two ends of bearing rib are welded with the internal surface of outer cylinder body and spindle nose respectively.But in use find; after Long-Time Service; the position that roller is the most easily damaged concentrates on spindle nose; often can there is spindle nose fracture; trace it to its cause because high temperature causes impact to spindle nose when being welding, form stress in the welding part of spindle nose and concentrate distortion, simultaneously because high temperature action changes material internal structure; when roll body is because of long-term load work, roll shaft welding part stress is caused to concentrate and rupture.
Summary of the invention
For solving the technical problem that current roller spindle nose easily occurs to rupture, the utility model provides a kind of resistance to stress endurance roller.
For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is: a kind of resistance to stress endurance roller, comprise outer cylinder body, end plate is provided with at the two ends of outer cylinder body, spindle nose and bearing rib, it is characterized in that: on described spindle nose, interference connects an axle sleeve, this axle sleeve adopts the assembling of heat expansion method, and the bearing rib of described end plate and outer cylinder body inside is welded and fixed with the internal surface of outer cylinder body and axle sleeve respectively.
The beneficial effects of the utility model are: can prevent from concentrating spindle nose formation stress during welding by increasing axle sleeve, can not damage simultaneously, effectively can increase the working life of roller to spindle nose material.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figure 1, a kind of resistance to stress endurance roller, comprises outer cylinder body 1, is provided with end plate 2 at the two ends of outer cylinder body, spindle nose 3 and bearing rib 4.
As shown in Figure 1, on spindle nose 3, interference connects an axle sleeve 5, and this axle sleeve 5 adopts heat expansion method to assemble, and the bearing rib 4 of end plate 2 and outer cylinder body inside is welded and fixed with the internal surface of outer cylinder body 1 and axle sleeve 5 respectively.
After adopting said structure, roller is in making course of working, welding part because of spindle nose and end plate, bearing rib etc. is inlayed in advance and has been added axle sleeve, thus to avoid in welding process because high temperature action is on the impact of spindle nose material, eliminate roll body to greatest extent and in use produce stress concentration phenomenon.
Claims (1)
