Abstract
The utility model provides a synchronous belt pulley which comprises a pulley body and a shaft sleeve. The pulley body is provided with an axial pin hole. The pulley body is sleeved on an outer ring of the shaft sleeve. The shaft sleeve is a step shaft sleeve. A step of the shaft sleeve is provided with an axial pin hole. The pulley body is connected with the shaft sleeve by a safety pin. The synchronous belt pulley is provided with the safety pin so as to have an overload protection function. When the synchronous belt pulley with the safety pin is overloaded, a motor or important parts are protected from being damaged by shearing the safety pin, so that the loss is minimized.
Description
Technical field
The utility model relates to a kind of synchronous pulley, belongs to mechanical transmission fields.
Background technique
The engagement driving that band transmission synchronously is made up of synchronous band and synchronous pulley, its motion and power are by being with the tooth transmission that is meshed with the gear teeth.Compare with the normal tape transmission, it is non-slip when transshipping advantage, shortcoming such as being with transmission to have between band and belt wheel not have slide relative, velocity ratio is constant, transmission efficiency is high, compact structure, wear resistance are good synchronously, can cause the damage of motor or important parts.
The model utility content
The technical problems to be solved in the utility model is to overcome existing defective, and a kind of synchronous pulley is provided, and can protect motor or important parts not to be damaged when overload.
In order to solve the problems of the technologies described above, the utility model provides following technological scheme:
A kind of synchronous pulley comprises wheel body, axle sleeve and safety pin; One axial pin-and-hole is arranged on the described wheel body, and wheel body is sleeved on the axle sleeve outer ring, and described axle sleeve is the ladder axle sleeve, and an axial pin-and-hole is arranged on the axle sleeve step, and described wheel body is connected by safety pin with axle sleeve.
Further, be provided with clamp near the pin-and-hole of described wheel body one end face, clamp is connected by screw with wheel body.
Further, on the tail end circumferential surface of described safety pin a seam is arranged, described clamp is embedded in the seam.
Further, be provided with guide in the pin-and-hole of described wheel body, be provided with guide in the pin-and-hole of described axle sleeve.
The utility model proposes a kind of synchronous pulley, have safety pin, make it have overload protection function.This synchronous pulley that has a safety pin during by overload cutting off of safety pin protect motor or important parts not to be damaged, loss is dropped to minimum.
Description of drawings
Accompanying drawing is used to provide further understanding of the present utility model, and constitutes the part of specification, is used from explanation the utility model with embodiment one of the present utility model, does not constitute restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of a kind of synchronous pulley of the utility model;
Fig. 2 is the left view of a kind of synchronous pulley of the utility model.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.
Band transmission synchronously is by driving pulley, band and driven pulley are formed synchronously, and its motion and power are by driving pulley, be with and the driven pulley transmission that is meshed synchronously.A kind of synchronous pulley described in the utility model is a driven pulley.
As shown in Figure 1 and Figure 2, a kind of synchronous pulley, the inner ring of wheel body 1 matches with axle sleeve 5 outer rings, wheel body 1 has an axial pin-and-hole, also has an axial pin-and-hole on the described axle sleeve 5, and the pin-and-hole of wheel body 1 is identical with the pin-and-hole radial position on the axle sleeve 5, safety pin 2 penetrates the pin-and-hole of wheel body 1 and the pin-and-hole on the axle sleeve 5, wheel body 1 links together by safety pin 2 with axle sleeve 5, and the clamp 7 that is fixed in wheel body 1 end face inserts in the seam of safety pins 2, prevents the axial motion of safety pin 2.Clamp 7 is fixed in the end face of wheel body 1 by screw 6.
When cutting off, damage the pin-and-hole wall for fear of safety pin 2, add guide I 3 in the pin-and-hole on the wheel body 1, add guide II 4 in the pin-and-hole of described axle sleeve 5.Safety pin 2 material selections 45 steel, and carry out quenching with Subsequent tempering, and guide I 3, guide II 4 and safety pin 2 are Spielpassung.
Because wheel body 1 is fixing with safety pin 2 with axle sleeve 5, after fixing a breakdown, changing new safety pin 2 can turn round again.
The utility model proposes a kind of synchronous pulley, have safety pin, make it have overload protection function.This synchronous pulley that has a safety pin during by overload cutting off of safety pin protect motor or important parts not to be damaged, loss is dropped to minimum.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, it still can be made amendment to the technological scheme that aforementioned each embodiment put down in writing, and perhaps part technical characteristics wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
