Abstract
The utility model provides a safe locking structure for preventing a riding wheel main shaft nut from loosing and falling off. The safe locking structure comprises a riding wheel (1) and a main shaft (8), wherein the riding wheel (1) is in working fit with the main shaft (8) through a bearing (2); the riding wheel (1) is in buckled fit with a sealing cover (3); one end of the bearing (2) is provided with a shaft head nut (5); and the end of the main shaft (8) is provided with a backstop baffle (4). According to the utility model, the end of the main shaft is provided with the backstop baffle which is in compression fit with the shaft head nut, and double screws are provided to be beneficial to the taking out of the screws along the rotation direction, so that the shaft head nut is prevented from loosing and falling off, and the phenomenon of riding wheel displacement caused by the loosing of the nut of the main shaft is avoided. The safe locking structure is simple in structure, simple and convenient in implementation, low in manufacturing cost, and capable of effectively preventing the nut of the main shaft of the riding wheel from loosing and falling off, reducing the maintenance of equipment and increasing the production efficiency.
Description
Technical field
The utility model belongs to mechanical equipment technical field, is specifically related to a kind of simple in structurely, is easy to implement, and fabricating cost is cheap, can effectively prevent the safe locking structure of support roller mainshaft nut loose or dislocation.
Background technique
The mineral aggregate discharge point support roller of prior art in use can be because becoming flexible appears in mainshaft nut, thereby cause support roller to produce displacement, and even fall into discharge bin, has the accident risk that damages disintegrator, economic loss not only, and have a strong impact on manufacturing efficiency.For this reason, develop a kind of simple in structurely, be easy to implement, fabricating cost is cheap, and the safe locking structure that can effectively prevent support roller mainshaft nut loose or dislocation is the key that addresses this problem, and favourable safety in production, enhance productivity.
The model utility content
It is a kind of simple in structure that the purpose of this utility model is to provide, and fabricating cost is cheap, is easy to implement, and can effectively prevent the safe locking structure of support roller mainshaft nut loose or dislocation.
The purpose of this utility model is to realize like this, relate to support roller and main shaft, described support roller coordinates by bearing working with main shaft, and described support roller coordinates with the sealing cover seizing type, described bearing one end arranges axis head nut, and described spindle nose arranges the anti-back baffle plate.
The utility model is by the anti-back baffle plate is set at spindle nose, and with the axis head nut press fit, two screws are provided with and help prevent that screw threads is to deviating from, thereby stops the axis head nut loose or dislocation, stops support roller produces displacement because mainshaft nut is loosening phenomenon generation.The utility model is simple in structure, is easy to implement, and fabricating cost is cheap, can effectively prevent support roller mainshaft nut loose or dislocation, reduces the maintenance of equipment, has improved manufacturing efficiency.
The accompanying drawing explanation
Fig. 1 is the utility model overall structure cross-sectional schematic;
In figure: 1-support roller, 2-bearing, 3-sealing cover, 4-anti-back baffle plate, 5-axis head nut, 6-screw, 7-locating stud, 8-main shaft.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but must not to the utility model, be limited by any way, any change or improvement based on the utility model training centre is done, all belong to protection domain of the present utility model.
As shown in Figure 1, the utility model relates to support roller 1 and main shaft 8, and described support roller 1 coordinates by bearing 2 work with main shaft 8, and described support roller 1 coordinates with sealing cover 3 seizing types, described bearing 2 one ends arrange axis head nut 5, and described main shaft 8 ends arrange anti-back baffle plate 4.
Described anti-back baffle plate 4 is fixed in main shaft 8 ends by screw 6, with axis head nut 5 press fit.
The diameter of described anti-back baffle plate 4 diameters and axis head nut 5 is suitable.
Described main shaft 8 ends arrange at least two screws, with screw 6, coordinate and make anti-back baffle plate 4 and main shaft 8 end drive fits.
Described screw 6 is sunk screw, with the counter sink work on anti-back baffle plate 4, coordinates.
Described anti-back baffle plate 4 diameters are greater than the diameter of axis head nut 5.
Described anti-back baffle plate 4 is by locating stud 7 and main shaft 8 end centralized positionings.
Working principle of the present utility model and working procedure:
The utility model, by the anti-back baffle plate is set at spindle nose, with the axis head nut press fit, prevents that effectively axis head nut from getting loose.Two screws are provided with and help prevent that screw threads is to deviating from, thereby stop the axis head nut loose or dislocation, stop support roller produces displacement because mainshaft nut is loosening phenomenon generation.During actual the use, remove the sealing cover on support roller, at spindle nose, stamp corresponding with the screw of anti-back baffle plate screw, the alignment of shafts stamp with the anti-back baffle plate on locating stud want the pin-and-hole that coordinates, after axis head nut is tightened, load onto the anti-back baffle plate and get final product, finally install sealing cover, namely complete the safe locking structure transformation that prevents support roller mainshaft nut loose or dislocation.The utility model is simple in structure, is easy to implement, and fabricating cost is cheap, can effectively extend the safe handling time limit of support roller, reduces maintenance cost, enhances productivity.
