[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0024] In the description of the utility model, it is necessary to explain that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model. In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance. The utility model will be further described in detail below with reference to the drawings.
[0025] In the utility model, unless otherwise expressly specified and limited, the terms "mounting", "connection", "connection", "fixing" and the like should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or the communication between two elements or the interaction relationship between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0026] As shown in Figures 1 to 5 The utility model provides a kind of hollow pulley, including pulley tooth support structure 1, pulley tooth 2, pulley tooth sludge groove 3, pulley tooth support structure auxiliary sludge groove 4, pulley and transmission input or output shaft's fixed mechanism 5.
[0027] Compared with the pulley tooth support structure 1 arranged in the middle of pulley tooth 2, it can ensure that pulley tooth 2, pulley tooth support structure 1 and transmission belt are uniformly stressed when the belt transmission system bears huge load, and when the pulley is elastically deformed due to overload, pulley tooth 2 and pulley tooth support structure 1 are only subjected to force in the plane direction of pulley tangent, avoiding damage to each structure of the pulley under high load, including the risk of rupture, tearing and fatigue of the pulley and the belt, improving the adaptability of the belt transmission system under the condition of torque mutation and overload, and improving the overall robustness of the transmission system.
[0028] The belt wheel tooth mud discharging groove 3 is a hollow structure at the tooth root of two adjacent belt wheels, and when the conventional belt transmission system works in a harsh environment (mud, rain, snow, weeds, shrubs, stones, etc.), foreign matters are easily stuck in the meshing position of the belt wheel and the belt, which may cause serious consequences such as aggravation of wear, tooth jumping, belt falling off, and damage to the belt structure. The belt wheel with the belt wheel tooth mud discharging groove 3 can squeeze out foreign matters from the belt wheel tooth mud discharging groove 3 in most cases, thereby improving the operation stability of the overall transmission system. The degree of hollowing of the belt wheel tooth mud discharging groove 3 depends on the tooth shape, the single tooth height, the number of belt wheel teeth, the number of belt teeth, the width of the belt, the working environment of the belt transmission system, the processing and manufacturing process, and other comprehensive factors.
[0029] If there is only the belt wheel tooth mud discharging groove 3 but no belt wheel support structure auxiliary mud discharging groove 4, there will be no impact in the early stage, but when the belt wheel teeth 2 are worn, the belt and the unevenly worn belt wheel teeth 2 will not be fully engaged, which may cause the noise to increase, the stress on both sides and the middle part of the belt wheel teeth 2 and the belt teeth to be uneven, and the possibility of serious consequences such as tooth jumping, belt falling off, and damage to the belt structure to increase. The belt wheel tooth mud discharging groove 3 and the belt wheel support structure auxiliary mud discharging groove 4 cooperate with each other to produce a synergistic mud discharging effect during the operation of the belt transmission system.
[0030] As shown in Figure 5 The fixing mechanism 5 of the belt wheel and the transmission input or output shaft generally refers to fixed connection, and can also be detachable connection or integral connection. The fixing mechanism 5 can be mechanical connection, electrical connection, direct connection, indirect connection through an intermediate medium, or internal connection of two elements.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or equivalently replace some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
