Description

Technical Field

[0001] This utility model belongs to the field of synchronous belt pulley technology, and particularly relates to a self-cleaning structure for chip grooves in synchronous belt pulleys. Background Technology

[0002] Synchronous belt pulleys are typically made of materials such as steel, aluminum alloy, cast iron, and brass. Their inner holes can be round, D-shaped, or tapered. Synchronous belt drives consist of a closed-loop rubber belt with evenly spaced teeth on its inner surface and corresponding pulleys. During operation, the belt teeth mesh with the pulley teeth to transmit motion and power. This is a meshing transmission, thus possessing the characteristics of gear drives, chain drives, and flat belt drives. It is widely used in the automotive, textile, printing and packaging equipment, sewing equipment, office equipment, laser engraving equipment, tobacco, financial equipment, stage lighting, communication and food machinery, medical machinery, steel machinery, petrochemical, instrumentation, and various precision machine tools industries. To achieve efficient impurity containment and increase the stability of the meshing transmission, chip grooves are created on the tooth surface to prevent impurities from accumulating in the meshing area.

[0003] Existing synchronous belt pulleys mostly have linear chip grooves, which cannot clean impurities themselves. This leads to excessive accumulation of impurities, increased transmission failures, and a significant reduction in the service life of the synchronous belt pulley. Utility Model Content

[0004] The purpose of this invention is to provide a self-cleaning structure for the chip collection groove of a synchronous belt pulley. Through physical design, the chip collection groove, chip discharge hole, and chip discharge pipe effectively guide dust and debris automatically into the chip discharge pipe, avoiding manual intervention and reducing maintenance costs and labor intensity. The rotation of the impeller and centrifugal wheel structures generates negative pressure and centrifugal force, effectively removing dust and debris and preventing debris accumulation near the synchronous belt and pulley structure, thus avoiding blockage or interference with the transmission system. The combination of negative pressure and centrifugal force ensures that dust and debris can flow smoothly from the chip discharge hole to the chip discharge pipe, and finally be thrown into the chip discharge hopper by centrifugal force, thereby efficiently removing and collecting dust and debris. By utilizing the combination of negative pressure and centrifugal force, efficient dust discharge and cleaning are achieved without relying on large power consumption or additional drive equipment, further reducing the cost of use. This invention aims to solve the problem that existing synchronous belt pulley chip collection grooves are mostly linear structures, which cannot clean impurities themselves, are prone to excessive impurity accumulation, increase transmission failures, and greatly reduce the service life of synchronous belt pulleys.

[0005] This utility model is implemented as follows: a self-cleaning structure for a chip groove in a synchronous belt pulley, comprising:

[0006] The wheel structure has a chip groove and a chip discharge hole for discharging impurities.

[0007] The wheel structure is also equipped with an axle assembly and a chip removal assembly;

[0008] The shaft assembly includes a bushing, a mounting shaft, a fixing pin, a first fixing hole, and a second fixing hole, and is used to form a power transmission system with the wheel structure;

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] It is understood that the terms “first” and “second” as used herein may be used to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.

[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0028] like Figures 1 to 4 As shown, a self-cleaning structure for a chip groove in a synchronous pulley, according to an embodiment of the present invention, includes:

[0029] The wheel structure 1 has a chip groove 11 and a chip discharge hole 12 for discharging impurities.

[0030] The wheel structure 1 is also equipped with a shaft assembly 2 and a chip removal assembly 3;

[0031] Shaft assembly 2 includes bushing 21, mounting shaft 22, fixing pin 23, first fixing hole 24 and second fixing hole 25, and is used to form a power transmission system with wheel structure 1;

[0032] Chip removal assembly 3 includes:

[0033] Chip removal pipe 31 is movably mounted on wheel structure 1;

[0034] The chip discharge hopper 32 is fixedly installed on the end face of the chip discharge pipe 31;

[0035] The wind turbine structure 33 is fixedly mounted on the mounting shaft 22;

[0036] Centrifugal wheel structure 34 is fixedly mounted on the end face of mounting shaft 22;

[0037] Specifically, as a further embodiment of this utility model, the chip groove 11 is inclinedly formed on the wheel structure 1, and the number of chip grooves 11 is several, and the several chip grooves 11 are evenly distributed on the wheel structure 1.

[0038] Specifically, as a further embodiment of this utility model, the number of chip removal holes 12 is the same as the number of chip receiving grooves 11, and several chip removal holes 12 are vertically and equidistantly opened on the wheel structure 1.

[0039] In this embodiment of the invention, in practical application, the wheel structure 1 is connected to the synchronous belt to form a power system transmission. When dust and debris are generated between the synchronous belt and the wheel structure 1 due to wear and environmental issues, the dust and debris will first fall into the chip collection groove 11. Because the dust and debris are covered and blocked by the synchronous belt and affected by the rotational force, the dust and debris will slide along the path of the chip collection groove 11 until it falls into the chip discharge pipe 31 through the chip discharge hole 12. The mounting shaft 22 will rotate synchronously with the wheel structure 1, thereby driving the impeller structure 33 and the centrifugal wheel structure 34 to rotate. When the impeller structure 33 rotates, it will generate a negative pressure force, causing air to flow out from the chip discharge hole 12. When the dust enters the chip removal pipe 31, it is subjected to the force of airflow, which prevents the dust from accumulating near the chip removal hole 12 and avoids clogging or interfering with the transmission of the wheel structure 1 and the synchronous belt. The dust flows with the air and is blown downwards from the chip removal pipe 31. At this time, the centrifugal wheel structure 34 and the fan wheel structure 33 rotate synchronously. When the dust falls into the area of ​​the centrifugal wheel structure 34, it will be subjected to the centrifugal force of the rapidly rotating centrifugal wheel structure 34, causing the dust to be thrown against the inner wall of the chip removal hopper 32. Due to the structure and shape of the chip removal hopper 32, the dust will fall out of the chip removal hopper 32 under the action of gravity and can be collected by setting a collection cylinder.

[0040] Through physical design, the chip trough 11, chip discharge hole 12, and chip discharge pipe 31 effectively guide dust and debris automatically into the chip discharge pipe 31, avoiding manual intervention and reducing maintenance costs and labor intensity. The rotation of the impeller structure 33 and the centrifugal wheel structure 34 generates negative pressure and centrifugal force, effectively removing dust and debris and preventing debris from accumulating near the synchronous belt and wheel structure 1, thus avoiding blockage or interference with the transmission system. The combination of negative pressure and centrifugal force ensures that dust and debris can flow smoothly from the chip discharge hole 12 to the chip discharge pipe 31, and finally be thrown towards the chip discharge hopper 32 by centrifugal force, thereby efficiently removing and collecting dust and debris. By utilizing the combination of negative pressure and centrifugal force, efficient dust emission and cleaning are achieved without relying on large power consumption and additional drive equipment, further reducing the cost of use.

[0041] It should be noted that both the wind turbine structure 33 and the centrifugal wheel structure 34 are mature technical solutions in the prior art and are common knowledge in the field. The applicant will not elaborate further on them here.

[0042] Specifically, as a further embodiment of this utility model, the bushing 21 is fixedly installed on the wheel structure 1, the mounting shaft 22 is sleeved on the wheel structure 1 and the bushing 21, and the fixing pin 23 is inserted into the bushing 21 to limit the mounting shaft 22.

[0043] Specifically, as a further embodiment of this utility model, the bushing 21 is also provided with a first fixing hole 24 and a second fixing hole 25. The first fixing hole 24 cooperates with a screw to limit and fix the fixing pin 23, and the second fixing hole 25 cooperates with a screw to limit and fix the mounting shaft 22.

[0044] In this embodiment of the utility model, in actual application, the mounting shaft 22 is sleeved on the bushing 21 and the wheel structure 1. The fixing pin 23 is inserted into the hole groove on the bushing 21 to restrict the rotation of the mounting shaft 22. At this time, the first fixing hole 24 and the second fixing hole 25 are used to install screws, thereby fixing the fixing pin 23, the mounting shaft 22 and the bushing 21 again, which further increases the stability between the mounting shaft 22 and the wheel structure 1.

[0045] like Figures 1 to 4 As shown, as a further embodiment of the present utility model, the chip discharge hopper 32 is funnel-shaped, and an mounting plate 321 is fixedly connected to the outer wall of the chip discharge hopper 32. The mounting plate 321 has mounting holes for installing and fixing the chip discharge hopper 32 and the chip discharge pipe 31.

[0046] In this embodiment of the utility model, in practical application, the funnel-shaped chip hopper 32 causes dust and debris to slide down under the action of gravity, which facilitates the collection of dust and debris. The mounting holes on the mounting plate 321 facilitate the support and fixation of the equipment by bolts or the like.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
