Description
Technical Field
The utility model relates to the technical field of agricultural machinery, in particular to an economical composite belt pulley.
Background
The belt pulley is widely applied to various mechanical equipment, and belt transmission is completed through the belt pulley; most of the existing belt pulleys adopt a casting process, so that the belt pulleys are integrally formed; this often needs to consume a large amount of mineral resources, with the consumption of mineral resources, the price is promoted gradually, make the belt pulley cost raise; and the pulley by casting is often too heavy, so that driving the pulley consumes more energy, and the indirect cost thereof increases, so that an economical pulley is needed.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects in the prior art, the utility model provides an economical composite belt pulley to reduce the production cost of the belt pulley, and reduce the weight and the use cost of the belt pulley.
In order to achieve the purpose, the utility model provides an economical composite belt pulley which comprises a shaft sleeve and a wheel hub part, wherein one end of the shaft sleeve is provided with a limiting shaft shoulder, a plurality of axial key grooves are processed in the outer wall of one circle of the limiting shaft shoulder, the wheel hub part is made of SMC composite materials and is pressed in the limiting shaft shoulder, and the wheel hub part is matched with the key grooves to realize circumferential positioning.
Further in order to improve the installation structural strength of the belt pulley, the shaft sleeve is made of steel materials.
Further in order to improve the stability of the installation structure of the belt pulley, a positioning key groove for installation positioning is processed in the shaft sleeve.
The utility model has the beneficial effects that: the utility model structurally combines the hub made of SMC composite material with the shaft sleeve to form the belt pulley, realizes the assembly connection of the belt pulley through the shaft sleeve, ensures the connection strength, greatly lightens the weight of the integral hub part through the SMC composite material, greatly reduces the use of steel, reduces the direct raw material cost, and lightens the weight of the whole composite belt pulley because the weight of the hub SMC composite material with the same size is greatly smaller than that of the steel, thereby reducing the indirect energy cost during use.

Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
It is to be noted that, unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the utility model pertains.
As shown in fig. 1, an embodiment of the present invention is: an economical composite belt pulley comprises a shaft sleeve 1 and a wheel hub part 2, wherein the wheel hub part 2 is provided with a plurality of annular limiting grooves for mounting a belt, and a rough layer is arranged in the annular limiting grooves, so that the friction coefficient of the belt is improved, and the friction force between the belt and the wheel hub is ensured; one end of the shaft sleeve 1 is provided with a limiting shaft shoulder 13, a plurality of axial key grooves 12 are processed in the outer wall of one circle of the limiting shaft shoulder 13, the hub part 2 is made of SMC composite materials, the hub part 2 is pressed in the limiting shaft shoulder 13 through processes such as hot pressing and the like, the circumferential positioning is realized by matching the hub part 2 with the key grooves 12, the hub part 2 is ensured, the shaft sleeve 1 is made of steel materials, and further, the installation structural strength of the belt pulley is improved; the wheel hub made of SMC composite materials is combined with the shaft sleeve 1 to form the belt pulley, the assembly connection of the belt pulley is realized through the shaft sleeve 1, the connection strength is guaranteed, the weight of the whole wheel hub part 2 is greatly reduced through the SMC composite materials, the steel material usage is greatly reduced, the direct raw material cost is reduced, and the weight of the wheel hub SMC composite materials with the same size is only one fourth of that of the same steel material, so that the weight of the whole composite belt pulley is lightened, and the indirect energy cost in the use process is reduced.
In the above embodiment, in order to improve the heat dissipation, a plurality of heat dissipation grooves may be further processed on the two side surfaces of the hub portion 2, so as to improve the heat dissipation surface of the entire hub portion 2, ensure the sufficient heat dissipation of the hub, and further improve the stability of the pulley.
Further in order to improve the stability of the installation structure of the pulley, a positioning key groove 11 for installation and positioning is processed inside the shaft sleeve 1, so that when the pulley is installed on equipment, the circumferential positioning of the whole pulley is realized through the positioning key groove 11, and the circumferential torsion stability is ensured.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the utility model has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
