Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of precision accessories, in particular to an output gear applicable to an unmanned aerial vehicle (UAV). Background Art
[0002] In the power transmission system of a UAV, the output gear is one of the key components. It is mainly used to transmit the rotational motion of the motor to the propeller or other actuators to achieve the stable flight and precise control of the UAV. Therefore, the performance of the output gear directly affects the flight efficiency, stability and service life of the UAV.
[0003] However, there are generally two main problems with the current output gears applied to UAVs: First, most of these gears use traditional metal materials and structural designs, resulting in a relatively heavy weight, increasing the overall load of the UAV and reducing the endurance.
[0004] Second, the lubricating oil of the existing gear structure is often easily thrown onto the gear rod due to centrifugal force during operation, causing the surface of the gear rod to become slippery, and further leading to problems such as unstable transmission and increased wear.
[0005] In view of the above problems, we have developed an output gear applicable to UAVs. Summary of the Utility Model
[0006] The utility model discloses an output gear applicable to a UAV, aiming to solve the technical problems in the background art.
[0007] To achieve the above object, the utility model adopts the following technical solutions:
[0008] An output gear applicable to a UAV includes a gear body, and the gear body includes a transmission rod, a clamping rod, a ring body, teeth and a sleeve rod. The clamping rod is arranged at one end of the transmission rod, the ring body is arranged at the end of the clamping rod away from the transmission rod, the sleeve rod is arranged on the side of the ring body away from the transmission rod, and the teeth are equidistantly arranged on the outer side of the ring body.
[0009] The clamping rod is used to drive the gear body to rotate, and when the clamping rod rotates, it can drive the transmission rod to rotate, and then drive the ring body to rotate through the transmission rod. Since the ring body is provided with teeth, it can drive other gear structures to rotate through the teeth to achieve drive output.
[0010] In a preferred solution, a first limiting step is arranged between the transmission rod and the ring body, and a second limiting step is arranged between the sleeve rod and the ring body and on the side away from the first limiting step.
[0011] The first limiting step and the second limiting step are used to enhance the firmness of the ring body.
[0012] In a preferred embodiment, the gear body further includes a through hole which is arranged in a penetrating structure inside the transmission rod, the clamping rod, the ring body and the sleeve rod.
[0013] The through hole is used for passing through and guiding screws, so that the gear body can be connected and fixed to the driving source.
[0014] In a preferred embodiment, the gear body further includes a limit card slot which is equidistantly arranged on the outer side of the clamping rod.
[0015] The limit card slot can cooperate with the flat key on the driving source, so that the gear body can be limited, and further the gear body can rotate following the driving source.
[0016] In a preferred embodiment, the gear body further includes a sealing ring groove which is arranged on the end face of the ring body and outside the first limit step.
[0017] A sealing ring can be embedded in the sealing ring groove. In this way, when contacting with the driving source, the transmission rod and the clamping rod can be sealed. Thus, when lubricating oil is added to the tooth teeth, it can be avoided that the lubricating oil flows to the transmission rod and the clamping rod.
[0018] In a preferred embodiment, chamfers are provided at the corners of the sleeve rod, the first limit step and the clamping rod.
[0019] The provision of chamfers facilitates the installation and use of the gear body.
[0020] In a preferred embodiment, the gear body is of an integral structure and is made of a metal material or a plastic material.
[0021] The metal material and the plastic material can ensure the use state of the gear body.
[0022] The output gear applicable to a drone provided by the present utility model has the following advantages:
[0023] The clamping rod drives the transmission rod and the ring body to rotate. The tooth teeth on the ring body are engaged with other gears to achieve driving output. The limit step between the transmission rod and the ring body increases the structural strength and ensures the stable operation of the gear. The gear is fixed to the driving source through the through hole, and the limit card slot ensures synchronous rotation. The sealing ring groove prevents lubricating oil from leaking, ensuring that the lubrication only acts on the tooth teeth part. It ensures that the gear has an efficient transmission effect, realizes lightweight at the same time, ensures the lubrication effect and prolongs the service life of the gear.
