Description

Technical Field

[0001] This utility model relates to the field of mechanical tool technology, and in particular to a grooved wheel. Background Technology

[0002] In intermittent motion of mechanical transmissions, Geneva mechanisms are a widely used and common structure, mainly composed of a Geneva wheel and a swivel arm. Traditional Geneva wheels are typically machined as a single piece and used as an independent component. From a manufacturing perspective, while machined Geneva wheels ensure structural integrity and strength to a certain extent, they sacrifice later maintainability.

[0003] During long-term operation, the arc surface of the Geneva wheel inevitably comes into frequent contact and friction with the swing arm lever, gradually leading to wear. As wear accumulates, the gap between the Geneva wheel's arc surface and the swing arm increases. Once this gap exceeds the allowable range, the Geneva wheel's motion accuracy will be severely affected, making it unable to accurately coordinate with the swing arm to complete the predetermined gap movement task. At this point, due to the traditional integral structure design of the Geneva wheel, operators have no choice but to scrap the entire Geneva wheel and replace it with a brand new one. This situation is particularly prominent in some mechanical equipment that uses Geneva wheels frequently and operates under high intensity, such as indexing devices in automated production lines and winding mechanisms in textile machinery. Frequent Geneva wheel replacements not only consume a lot of manpower and resources for disassembly and installation, but the cost of purchasing new Geneva wheels is also considerable, greatly increasing the equipment's maintenance costs and frequency, and bringing many inconveniences and economic burdens to the company's production and operation. Utility Model Content

[0004] The purpose of this invention is to achieve adjustable clearance after wear by cleverly designing the arc surface of the Geneva wheel, thereby effectively reducing maintenance costs and frequency, and improving the reliability and economy of the Geneva wheel mechanism during long-term use.

[0005] To achieve the above objectives, this utility model provides a grooved wheel comprising: a main body, a driving groove at the center of the main body, a plurality of arcuate portions on the outer periphery of the main body, a sliding groove between adjacent arcuate portions, and the sliding groove extending radially along the main body; and

[0006] Multiple contact components are arranged radially spaced along the main body, connected to the arc portion, and capable of radial extension and retraction along the main body.

[0007] Preferably, the contact assembly includes a plurality of adjusting members, which are arranged radially spaced along the outer periphery of the body;

[0008] The side of the contact component closest to the arc portion mates with the arc portion, while the side of the contact component away from the arc portion is arc-shaped. Multiple contact components are spaced apart on the outer periphery of the main body, with the number of contact components being the same as the number of arc portions. The contact components are threadedly connected to the corresponding arc portions via adjusting parts.

[0009] Preferably, the contact assembly further includes multiple contact blocks, which abut against each other and the side of the multiple contact blocks near the arc portion cooperates with the arc portion. Each contact block is threadedly connected to the arc portion through an adjusting member.

[0010] Preferably, both the main body and the contact block are made of stainless steel.

[0011] Preferably, the drive groove includes a circular groove and a keyway, with the keyway located on the outer periphery of the circular groove and communicating with it.

[0012] Preferably, there are multiple keyways, which are arranged symmetrically along the radial direction of the circular groove.

[0013] Preferably, the curved portion is provided with threaded holes, the number of which is the same as the number of adjusting members, and the adjusting members are provided with external threads, and the adjusting members are threadedly connected to the threaded holes.

[0014] Preferably, the main body is also provided with multiple through holes, which are arranged parallel to the drive groove and are arranged radially spaced along the main body.

[0015] Compared with existing technologies, the Geneva wheel of this invention offers the following advantages: Existing Geneva wheels often suffer from wear during operation, leading to loss of engagement with the driving components and difficulty in adjusting the engagement relationship. This invention addresses this issue by providing a driving groove at the center of the Geneva wheel body, enabling efficient power transmission. Multiple arc-shaped sections on the outer circumference of the Geneva wheel body, with sliding grooves between adjacent arc sections, ensure stability and efficiency during power transmission. The contact components are radially arranged and can be adjusted for extension and retraction as needed, solving the problem of difficulty in adjusting the engagement between the Geneva wheel and other driving components in traditional Geneva wheels. This not only allows for re-engagement between the Geneva wheel and other driving components through adjustment of the contact components but also effectively extends service life. It is particularly suitable for equipment requiring high precision and long-term operation, exhibiting good adaptability and reliability. Attached Figure Description

[0025] Multiple contact components 2 are arranged radially spaced along the main body 1. The contact components 2 are connected to the arc portion 12 and can extend and retract radially along the main body 1.

[0026] Based on the above scheme, this scheme utilizes a drive groove 11 at the center of the Geneva body 1 to achieve efficient power transmission. Multiple arc-shaped portions 12 are located on the outer periphery of the Geneva body 1, and sliding grooves 13 are designed between adjacent arc-shaped portions 12 to ensure stability during power transmission. The contact component 2 is arranged radially and can be adjusted for extension and retraction as needed, solving the problem of difficult adjustment of the Geneva wheel and its fit with other driving components in traditional Geneva wheels. This not only allows the Geneva wheel and other driving components to be refitted through adjustment of the contact component 2, but also effectively extends their service life. It is particularly suitable for equipment requiring high precision and long-term operation, exhibiting good adaptability and reliability.

[0027] Furthermore, the contact assembly 2 includes a plurality of adjusting members 21, which are arranged radially spaced along the outer periphery of the body 1.

[0028] The side of the contact component 2 closest to the arc portion 12 cooperates with the arc portion 12, and the side of the contact component 2 away from the arc portion 12 is arc-shaped. Multiple contact components 2 are spaced apart on the outer periphery of the main body 1. The number of contact components 2 is the same as the number of arc portions 12.

The adjusting members 21 make the installation and adjustment of the grooved wheel more flexible, with better adaptability and adjustability, further improving the ease of maintenance of the grooved wheel.

[0030] Furthermore, the contact assembly 2 also includes a plurality of contact blocks 22, which abut against each other and the side of the plurality of contact blocks 22 near the arc portion 12 cooperates with the arc portion 12. Each contact block 22 is threadedly connected to the arc portion 12 through an adjusting member 21.

[0031] Based on the above scheme, the contact assembly 2 is provided with multiple contact blocks 22, which abut against each other.

The keyway 112 design has good anti-slip capability, which can avoid loosening caused by mechanical vibration or load changes, further improving the working accuracy and reliability of the Geneva wheel.

[0036] Furthermore, there are multiple keyways 112, which are arranged radially symmetrically along the circular groove 111.

[0037] Based on the above scheme, multiple keyways 112 are radially symmetrically arranged along the circular groove 111, making the power transmission of the Geneva wheel more uniform, reducing asymmetrical loads during power transmission, and avoiding mechanical wear or failures caused by uneven loads. The radially symmetrical arrangement also effectively improves the overall balance of the Geneva wheel, reduces vibration, and enhances working stability and accuracy.

[0038] Furthermore, the arc portion 12 is provided with threaded holes, the number of which is the same as the number of adjusting members 21. The adjusting member 21 is provided with external threads, and the adjusting member 21 is threadedly connected to the threaded holes.
