Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical transmission technology, and more specifically, to a synchronous pulley with chip grooves. Background Technology
[0002] Synchronous pulleys are generally made of materials such as steel, aluminum alloy, cast iron, or brass. Their inner holes can be round, D-shaped, or tapered. They are key components in mechanical transmission devices that use a synchronous belt tightly fitted onto two or more synchronous pulleys and rely on the meshing of belt teeth and pulley teeth to transmit motion and power.
[0003] The shortcomings of existing technologies are as follows: In some working environments with many impurities, during the transmission process via synchronous pulleys and synchronous belts, the smooth, grooveless surface of traditional synchronous pulleys makes it easy for impurities to accumulate in the meshing area between the pulley and the belt. This can lead to slippage or jamming during transmission, reducing the smoothness and accuracy of the transmission, potentially altering the transmission ratio, and consequently affecting the overall operating performance and production quality of the equipment. Furthermore, the continuous accumulation of impurities in the meshing area between the pulley and the belt exacerbates friction and wear between the teeth of the pulley and the belt, shortening the service life of components, increasing maintenance costs, and reducing production efficiency. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a timing pulley with chip grooves to solve the problems existing in the background art.
[0005] This utility model provides the following technical solution: a timing pulley with chip grooves, comprising:
[0006] Synchronous belt pulley;
[0007] The tooth surface of the synchronous pulley is provided with chip grooves at equal intervals;
[0008] The tooth surfaces of the synchronous pulleys are all equally spaced grooves, and the two grooves are connected to the chip groove.
[0009] Preferably, annular baffles are fixedly installed on the outer side of each synchronous pulley, and the two annular baffles are located on both sides of the tooth surface of the synchronous pulley.
[0010] Preferably, the plurality of chip grooves are adapted to the tooth surface curvature of the timing pulley.
[0011] Preferably, the central shaft groove of the synchronous pulley is provided with a flat keyway, which is adapted to the external shaft end.
[0012] Preferably, the annular baffle has an inclination.
[0013] The beneficial effects of this utility model are:
[0014] 1. In this utility model, by setting a chip-collecting groove and two spacing grooves, it is convenient to open multiple equidistant oblique contours on the tooth surface of the synchronous pulley to form a continuous chip-collecting space. This allows for the rapid collection of chips or dust during the transmission process, avoiding the slippage or jamming caused by the accumulation of impurities in the meshing area between the tooth surface of the synchronous pulley and the synchronous belt due to the smooth surface of the pulley without grooves in traditional synchronous pulleys. It also avoids the problem of chips or dust aggravating the friction and wear between the synchronous belt and the tooth surface of the synchronous pulley, extending the service life of the parts, reducing maintenance costs, and improving production efficiency.
[0015] 2. In this utility model, by installing annular baffles on both sides of the synchronous belt pulley tooth surface, the transmission trajectory of the synchronous belt is corrected to prevent deviation; by setting the curvature of the synchronous belt pulley tooth surface to be consistent with the curvature of the chip groove, the problem of uneven tooth surface caused by chip accumulation is reduced, and the impact and vibration during the transmission process are avoided, making the transmission smoother; by setting the two annular baffles at an inclination, the blocked impurities slide down along the inclined surface under the action of gravity, which facilitates the discharge of impurities outside the transmission structure and prevents impurities from accumulating on the synchronous belt pulley.

[0020] The following will be combined with the appendix Figures 1 to 2 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0021] Please see Figure 1-2 This utility model embodiment provides a timing pulley with chip grooves, comprising:
[0022] Synchronous belt pulley 1;
[0023] The tooth surface of the synchronous belt pulley 1 is provided with chip grooves 2 at equal intervals;
[0024] The tooth surface of the synchronous pulley 1 is provided with equally spaced slots 3, and the two slots 3 are connected to the chip groove 2.
[0025] In practical applications, when the tooth surface of the synchronous pulley 1 engages with the synchronous belt, it drives the tooth surface of the synchronous pulley 1 to form a continuous chip-collecting space. This allows chips or dust to accumulate in the chip-collecting groove 2 and two spacing grooves 3 on the tooth surface of the synchronous pulley 1, preventing chips or dust from accumulating between the smooth surface of the wheel body of the traditional synchronous pulley 1 and the synchronous belt, thus preventing jamming and wear.
[0026] This embodiment, by setting chip groove 2 and two spacing grooves 3, facilitates the formation of multiple equidistant oblique contours on the tooth surface of the synchronous pulley 1 to create a continuous chip-collecting space. This allows for the rapid collection of chips or dust during the transmission process, avoiding the slippage or jamming caused by the accumulation of impurities in the meshing area between the tooth surface of the synchronous pulley 1 and the synchronous belt due to the smooth surface of the pulley without grooves, as is common in traditional synchronous pulleys. It also prevents chips or dust from aggravating the friction and wear between the synchronous belt and the tooth surface of the synchronous pulley, extending the service life of components, reducing maintenance costs, and improving production efficiency.
[0027] Please see Figure 1-2 In a preferred embodiment of this utility model, annular baffles 4 are fixedly installed on the outer side of the synchronous pulley 1, and the two annular baffles 4 are located on both sides of the tooth surface of the synchronous pulley 1.
[0028] In this embodiment, annular baffles 4 are installed on both sides of the tooth surface of the synchronous belt pulley 1 to correct the transmission trajectory of the synchronous belt and prevent deviation.
[0029] Please see Figure 1-2 In a preferred embodiment of this utility model, the multiple chip grooves 2 are adapted to the tooth surface curvature of the synchronous pulley 1.
[0030] In this embodiment, by setting the curvature of the tooth surface of the synchronous pulley 1 to be consistent with the curvature of the chip groove 2, the problem of uneven tooth surface caused by chip accumulation is reduced, and the impact and vibration during the transmission process are avoided, making the transmission smoother.
[0031] Please see Figure 1-2 In a preferred embodiment of the present invention, the annular baffle 4 has an inclination.
[0032] In this embodiment, by setting the two annular baffles 4 to an inclination, the blocked impurities slide down the inclined surface under the action of gravity, which facilitates the discharge of impurities outside the transmission structure and avoids the accumulation of impurities on the synchronous pulley.
