Abstract
The utility model discloses a belt pulley connected through an expansion sleeve. The belt pulley connected through the expansion sleeve comprises a belt pulley body (5), a connecting hole (7) is opened in the center of the belt pulley body (5), a spindle (4) is arranged in the connecting hole (7) in a sleeve mode, an expansion sleeve step hole (7) is opened in the end of one end of the connecting hole (4), the inner diameter of the expansion sleeve step hole (7) is larger than that of the connecting hole (4), the expansion sleeve (3) is arranged in the expansion sleeve step hole (7) in a sleeve mode, the spindle (4) is arranged in the expansion sleeve (3) in a sleeve mode, and a plurality of thread holes (6) are opened in the outer head face of the expansion sleeve (3). The belt pulley connected through the expansion sleeve has beneficial effects that the belt wheel uses the connecting structure that the spindle is locked by the expansion sleeve, so that the belt wheel is simple in structure, the disassembly and assembly are facilitated, the spindle does not rotate relative to the belt pulley, the abrasion between the spindle and the central hole of the belt pulley is lowered, and the service life of the belt pulley is improved.
Description
Technical field
The utility model relates to disintegrator belt wheel connection structure, the belt pulley that particularly a kind of ringfeder connects.
Background technique
Belt pulley is the main parts size on disintegrator, belt pulley rotational relaxes the load impacting of disintegrator, energy reduction equipment noise aborning, and motion is got up steadily, simple framework, being convenient to adjust is also a large advantage of pulley movements, this exterior belt pulley transmission also has the function of overload protection, therefore the connection of belt pulley is particularly important thinks, belt pulley mostly is and is sleeved on main shaft at present, then with key, detachably connect, yet disintegrator is in operation running, impact force is larger, often it is overhauled, but when maintenance, belt pulley is not easy to assemble, and time-consuming, effort, indirectly affected manufacturing efficiency, improved cost of production.
Model utility content
The purpose of this utility model is to overcome the shortcoming of prior art, the belt pulley that provides the ringfeder of a kind of simple in structure, easy accessibility and long service life to be connected.
The purpose of this utility model is achieved through the following technical solutions: the belt pulley that a kind of ringfeder connects, it comprises belt pulley, belt pulley center offers attachment hole, in attachment hole, be set with main shaft, the termination of one end of attachment hole offers ringfeder step hole, and the internal diameter of ringfeder step hole is greater than the internal diameter of attachment hole, in ringfeder step hole, is set with ringfeder, ringfeder inner sleeve has main shaft, offers a plurality of tapped holes on the exterior edge face of described ringfeder.
Described tapped hole is evenly distributed on the same circumference of ringfeder 3 exterior edge faces.
In described belt pulley both ends of the surface, symmetry offers circular groove, evenly offers a plurality of through holes in circular groove.
The utlity model has following advantage: belt pulley of the present utility model adopts the linkage structure of ringfeder locking main shaft, make belt sheave structure simple, easy accessibility, and main shaft not relatively belt pulley rotate, the wearing and tearing of main shaft and belt pulley center hole have been reduced, the working life of having improved belt pulley.
Accompanying drawing explanation
Fig. 1 is structural profile schematic diagram of the present utility model;
Fig. 2 is that schematic diagram is looked on a left side of the present utility model;
In figure, 1-circular groove, 2-through hole, 3-ringfeder, 4-main shaft, 5-belt pulley, 6-tapped hole, 7-ringfeder step hole.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, protection domain of the present utility model is not limited to the following stated:
As depicted in figs. 1 and 2, the belt pulley that a kind of ringfeder connects, it comprises belt pulley 5, belt pulley 5 centers offer attachment hole 7, in attachment hole 7, be set with main shaft 4, the termination of one end of attachment hole 4 offers ringfeder step hole 7, the internal diameter of ringfeder step hole 7 is greater than the internal diameter of attachment hole 4, in ringfeder step hole 7, be set with ringfeder 3, ringfeder 3 inner sleeves have main shaft 4, on the exterior edge face of described ringfeder 3, offer a plurality of tapped holes 6, tapped hole 6 is evenly distributed on the same circumference of ringfeder 3 exterior edge faces, in belt pulley 5 both ends of the surface, symmetry offers circular groove 1, circular groove 1 is interior evenly offers a plurality of through holes 2, by offering circular groove 1 and through hole 2, alleviate the deadweight of belt pulley 5, convenient installation.
Working procedure of the present utility model is as follows: when belt pulley 5 is installed, belt pulley 5 is arranged on main shaft 4, then the screw that the interior installation of the tapped hole on ringfeder 36 matches with it, tighten screw, make ringfeder 3 and the complete locking of main shaft 4, and whole belt pulley 5 is symplex structure, thus counterweight point need not deliberately be found, thereby belt pulley 5 is extremely convenient in whole disassembly process.
Claims (3)
