Description

Technical Field

[0001] The utility model relates to the technical field of steering gears, in particular to a steering gear structure. Background Art

[0002] In the field of autonomous driving technology and mechanical control, the servo, as a key executive component, is responsible for manipulating the control surfaces (control surfaces) of aircraft, robots or other equipment to make precise rotations. Electric servos, as an important type of servos, are usually composed of electric motors, transmission components and clutches. Among them, the design of the transmission components has a direct impact on the performance of the servo, and the gear structure is the core part of the transmission components.

[0003] The transmission components of existing electric servos are mostly composed of multiple drive reduction gears. These gears are driven by electric motors to achieve power transmission and speed reduction to meet the precise rotation requirements of the rudder surface. However, the gear structures on these servos lack corresponding lubrication components, which cannot be lubricated in a timely manner. This can easily cause wear at the meshing parts of the gears due to excessive friction. This wear affects the stability of the gear meshing transmission. The gears are also easily corroded due to direct exposure to the outside world, shortening their service life. In view of this, we propose a servo gear structure. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-Figure 4 The utility model provides a technical solution: a steering gear gear structure, including a gear set 1, a transmission shaft 10 is provided on the gear set 1, a lubricating oil tank 2 is provided on the outside of the gear set 1, the transmission shaft 10 passes through the side plate of the lubricating oil tank 2 and is rotatably connected to the lubricating oil tank 2, a threaded adding pipe 25 connected to the interior of the lubricating oil tank 2 is fixedly installed on the top plate of the lubricating oil tank 2, a threaded cover 26 is threadedly connected to the threaded adding pipe 25, a conical box 22 is fixedly installed at the bottom of the lubricating oil tank 2, a collecting cylinder 23 is fixedly installed at the bottom of the conical box 22, a magnet 231 is fixedly installed on the bottom wall of the collecting cylinder 23, so as to add lubricating oil into the lubricating oil tank 2, realize lubrication operation of the gear set 1, reduce wear, and in addition, protecting the gear set 1 inside can also play an anti-corrosion effect.

[0026] In this embodiment, a plurality of mechanical seals 20 arranged at equal intervals are fixedly mounted on the left and right side plates of the lubricating oil tank 2. The transmission shaft 10 passes through the mechanical seal 20 and is rotationally connected to the mechanical seal 20, thereby realizing reasonable sealing operation of the side plate portion of the transmission shaft 10 passing through the lubricating oil tank 2 by using the mechanical seal 20.

[0027] Specifically, a transparent window 21 is provided on the side plate of the lubricating oil tank 2 . The transparent window 21 is arranged along the height direction of the lubricating oil tank 2 . The transparent window 21 is made of transparent material, which makes it easy to observe the amount of oil in the lubricating oil tank 2 through the transparent window 21 .

[0028] Furthermore, a warning line 211 is provided on the side plate of the lubricating oil tank 2 provided with the transparent window 21 , and the warning line 211 faces one side of the transparent window 21 , so as to facilitate comparison with the warning line 211 to understand the specific amount of lubricating oil added.

[0029] In addition, a slope 221 is provided on the bottom wall of the conical box 22, and the slope 221 is set to be inclined downward at 45° to 60°, so that the metal impurities dropped by the gear set 1 in the lubricating oil tank 2 due to friction can fall down along the slope 221 into the collection tube 23 and be adsorbed by the magnet 231 more smoothly.

[0030] It is worth noting that a plurality of support legs 24 arranged in a matrix are fixedly mounted on the bottom surface of the conical box 22 , and the distance between the bottom surface of the collecting cylinder 23 and the ground is greater than 3 cm, so that the support operation is achieved by using the support legs 24 .
