Description

Technical Field

[0001] This utility model relates to a traveling wheel, specifically a traveling wheel combining a parallel shaft planetary reducer. Background Technology

[0002] Traditional drive wheel designs face numerous challenges in existing wheeled mobile equipment, especially those operating in clean or space-constrained environments. Traditional drive wheel systems often employ open or semi-enclosed structures, which are prone to accumulating dust and debris over long-term use. This not only increases maintenance costs but can also adversely affect the normal operation of the equipment. Furthermore, grease leakage is a significant problem in traditional designs, contaminating the working environment and potentially damaging the equipment itself and surrounding devices.

[0003] On the other hand, the steering and walking mechanisms of traditional drive wheels are often designed to be complex and compact, which to some extent limits the size of the drive wheels, especially their diameter and width, thus affecting their load-bearing capacity and stability. Utility Model Content

[0012] In some embodiments, the outer wheel is bonded to the traveling wheel, or the outer wheel is elastically fitted onto the traveling wheel.

[0013] In some embodiments, it also includes:

[0014] A fixing pin is used to fix the connecting bearing to the fixing frame, and the outer ring of the connecting bearing can rotate relative to the fixing frame.

[0016] In some embodiments, the drive wheel fixing cavity has a second shaft limiting hole, and the fixing shaft of the drive wheel is located in the second shaft limiting hole.

[0017] The parallel shaft planetary reducer combined with the traveling wheel in this embodiment has a simple structure. It is installed by a fixed frame, which is tightly fitted with each component, resulting in good sealing and high stability. Attached Figure Description

The drive wheel 2 is located in the drive wheel mounting cavity 10. Similarly, the drive wheel mounting cavity 10 can also be sealed by a cover plate (not shown in the figure) to achieve the sealing of the motor 1 and the drive wheel 2.

[0023] The driven wheel fixing shaft 3 passes through the connecting bearing 5 and can be fixedly connected to the inner ring of the connecting bearing 5. It extends through the shaft cavity 11 of the fixing frame to the outside of the fixing frame. The driven wheel 4 is sleeved on the driven wheel fixing shaft 3 and located within the fixing frame, immediately adjacent to the drive wheel fixing cavity 10.
