Description

Technical Field

[0001] This utility model relates to the field of foot pedals, specifically to a foot pedal structure with a large bearing. Background Technology

[0002] Bicycle pedals are auxiliary devices used by people to pedal and provide forward power to bicycles. Currently, most bicycle pedals use small bearings. However, during pedaling, the foot may wobble laterally or apply force at an angle. Small bearings cannot effectively buffer these combined forces, resulting in uneven rotation. Therefore, this utility model proposes a pedal structure with a large bearing. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a large bearing foot pedal structure. By setting a deep groove ball bearing, it can withstand and effectively buffer the lateral swaying or oblique loss of force generated by the foot during pedaling, ensuring smooth rotation. At the same time, the deep groove ball bearing has a simple structure and good sealing performance, making it suitable as an outer bearing, which is convenient for installation and maintenance.

[0004] Technical solution

[0005] A large bearing foot pedal structure includes a foot pedal body, an inlet end provided inside the foot pedal body, a shaft core inserted into the inlet end, a deep groove ball bearing fixed at the rear end of the shaft core, a locking nut threaded to the inlet end abutting the outer side of the deep groove ball bearing, a dustproof sealing ring provided between the locking nut and the shaft core, and a flared limiting end located on the shaft core on the side of the dustproof sealing ring away from the inlet end.

[0006] Furthermore, the inlet end is provided with an internal thread, and the locking nut is threadedly connected to the internal thread.

[0007] Furthermore, the inner side of the internal thread is provided with a stepped portion for abutting against the deep groove ball bearing.

[0008] Furthermore, the inlet end is also provided with a metal ring that is fitted onto the shaft and is interference-fitted with the shaft.

[0009] Furthermore, a shaft hole is also connected deep within the inlet end.

[0010] Furthermore, a needle roller bearing rotatably connected to the shaft core is also abutted on the side of the shaft hole away from the inlet end.

[0011] Beneficial effects

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] By incorporating deep groove ball bearings, the system can withstand and effectively buffer lateral swaying or oblique force loss caused by footsteps during pedaling, ensuring smooth rotation. At the same time, deep groove ball bearings have a simple structure and good sealing performance, making them suitable as outer bearings for easy installation and maintenance. The compactness of needle roller bearings allows for a slimmer shaft design, while the large outer deep groove ball bearings provide sufficient structural strength, balancing lightweight and durability.

[0018] To better illustrate the content of this utility model, the following description is provided in conjunction with the accompanying drawings and embodiments:

[0019] have Figures 1-2 As shown, this utility model discloses a large bearing foot pedal structure, including a foot pedal body 7. The foot pedal body 7 has an inlet end 10 inside, and a shaft core 1 is inserted into the inlet end 10. A deep groove ball bearing 4 is fixed at the rear end of the shaft core 1. A locking nut 3 threaded to the inlet end 10 is abutted on the outer side of the deep groove ball bearing 4. A dustproof sealing ring 2 is provided between the locking nut 3 and the shaft core 1. A flared limiting end 12 located on the shaft core 1 is also provided on the side of the dustproof sealing ring 2 away from the inlet end 10.

[0020] Furthermore, an internal thread 8 is provided at the port of the inlet end 10, and the locking nut 3 is threadedly connected to the internal thread 8.

[0021] Furthermore, the inner side of the internal thread 8 is provided with a stepped portion 9 for abutting against the deep groove ball bearing 4.

[0022] Furthermore, the inlet end 10 is also provided with a metal ring 5 that is fitted onto the shaft core 1 and is interference-fitted with the shaft core 1.

[0023] Furthermore, the inlet end 10 is also connected to a shaft hole 11 at its depth.

[0024] Furthermore, a needle roller bearing 6 rotatably connected to the shaft core 1 is also abutted on the side of the shaft hole 11 away from the inlet end 10.

[0025] Specifically, the outer ring of the deep groove ball bearing 4 is limited and fixed by the step portion 9 and the locking nut 3, and the inner ring of the deep groove ball bearing 4 is limited and fixed by the interference fit of the metal ring 5 and the shaft core 1, thereby achieving the fixed installation of the shaft core 1 in conjunction with the needle roller bearing 6.
