Description

Technical Field

[0001] This utility model belongs to the field of gear chain technology, specifically a lightweight bicycle gear chain that can be rapidly prototyping. Background Technology

[0002] The bicycle chainring, also known as the crankset, is the part that connects the bottom bracket and crank of a bicycle. It is the most visible part of the chainring and is usually composed of multiple teeth. The shape, size, and spacing of these teeth are carefully designed. Different types of bicycles have different chainring tooth shapes. Road bike chainring teeth are sharper, which is conducive to a tight bite with the chain at high speeds and efficient power transmission. Mountain bike chainring teeth are thicker to cope with the high torque requirements of complex terrain. Chainring materials also vary, with aluminum alloy and carbon fiber being common. Current bicycle chainrings have long production cycles and low production speeds. Therefore, we propose a lightweight bicycle chainring that can be rapidly prototyped. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3A lightweight bicycle chainring that can be rapidly prototyping includes a chainring body 100. The chainring body 100 has a central hole 110, five sets of crank holes 120, each set of crank holes 120 having three sets of adjustment holes to facilitate adjustment to the desired installation position. The chainring body 100 also has five sets of lightweight holes 130 and five sets of connecting blocks 140, which are arc-shaped. The angle matches the operating angle. The arc-shaped design of the connecting block 140 improves the overall safety and stability of the device, as well as its overall rigidity. The crank hole 120 is located in the area of ​​the connecting block 140. A toothed ring 200 is provided on the outer side of the gear disc body 100, and multiple sets of teeth 210 are connected to the outer side of the toothed ring 200. The weight of the gear disc body 100 can be reduced by providing the lightweight hole 130. An arc-shaped area 300 is provided at the connection between the gear disc body 100 and the toothed ring 200. This arc-shaped area allows the chain...
