Technical Field

[0001] The utility model relates to the technical field of servos, and specifically relates to a multi-layer distributed drive type servo gear. Background Art

[0002] A servo refers to an actuator that controls the rotation of the aircraft rudder surface (control surface) in an autopilot, and is also widely used in various occasions that require precise angle control, such as robots, models, smart homes and other fields. A servo mainly consists of a housing, a circuit board, a driving motor, a speed reducer and a position detection element. Among them, the speed reducer mainly includes a plurality of meshing gears, and the plurality of gears are generally distributed in multiple layers up and down, making the transmission more stable and avoiding disorder.

[0003] There are many types of servos on the market. However, when most servos are specifically used, although their exteriors are provided with a housing for protection, the bottom of the housing lacks a corresponding shock absorption component, which is not conducive to achieving a certain shock absorption and buffering protection effect after being stressed. After vibration occurs, it is easy to cause errors or wear in the meshing of the internal precision gear components, affecting their use effect and bringing inconvenience to users. In view of this, we have proposed a multi-layer distributed drive type servo gear. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a multi-layer distributed drive type servo gear to solve the defects mentioned in the above background art.

The corresponding gears are meshed with each other. On the bottom shell of the servo main body, two symmetrically arranged fixed supports are fixedly installed. On the bottom surface of the fixed support, a support base is fixedly installed. A bottom shock absorption pad is clamped and matched between the two support bases. On the upper surface of the bottom shock absorption pad, a plurality of triangular pads arranged linearly at equal intervals are fixedly installed. On the bottom surface of the servo main body, a plurality of fixed pads arranged linearly at equal intervals are fixedly installed. The fixed pads are abutted against the upper surfaces of the corresponding triangular pads.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1 - 4 , the present invention provides a technical solution: a multi-layer distributed transmission type servo gear, including a servo main body 1, a plurality of transmission shafts 12 rotatably connected to the servo main body 1, and a plurality of gears 13 fixedly installed on the transmission shafts 12. The corresponding gears 13 are meshed with each other, and the plurality of gears 13 are distributed in multiple upper and lower layers. On the bottom shell of the servo main body 1, two symmetrically arranged fixed supports 19 are fixedly installed. On the bottom surface of the fixed support 19, a support base 18 is fixedly installed. A bottom shock pad 14 is clamped between the two support bases 18. On the upper surface of the bottom shock pad 14, a plurality of triangular cushion blocks 15 arranged linearly at equal intervals are fixedly installed. On the bottom surface of the servo main body 1, a plurality of fixed cushion blocks 16 arranged linearly at equal intervals are fixedly installed. The fixed cushion blocks 16 abut on the upper surfaces of the corresponding triangular cushion blocks 15. The bottom shock pad 14, the triangular cushion blocks 15, and the fixed cushion blocks 16 can all be made of rubber materials. The rubber materials have good shock absorption effects. After a downward extrusion force is generated at the servo main body 1 part, at this time, the bottom shock pad 14, the triangular cushion blocks 15, and the fixed cushion blocks 16 can absorb this part of the force and achieve the shock absorption effect.

[0027] In this embodiment, the cross-section of the bottom shock pad 14 is U-shaped, and the cross-sections of the triangular cushion blocks 15 and the fixed cushion blocks 16 are both triangular, so as to protect the triangular cushion blocks 15 and the fixed cushion blocks 16 inside by using the bottom shock pad 14.

[0028] Specifically, a plurality of bottom support and compression bars 17 arranged at equal intervals are fixedly installed on the bottom surface of the bottom shock pad 14. The cross-section of the bottom support and compression bar 17 is V-shaped. The bottom support and compression bar 17 can be made of PVC material to make it have a certain elasticity. After being stressed, the bottom support and compression bar 17 can also undergo a certain deformation to disperse the vibration force and achieve a further shock absorption effect.

[0029] Furthermore, a top cover 10 is provided on the top of the servo motor main body 1. Fixed frames 11 are fixedly installed on both the servo motor main body 1 and the top cover 10. The upper and lower fixed frames 11 are fixedly connected by a plurality of fastening screws, which is convenient for fixing operations.

[0030] In addition, a liquid injection hole 2 is provided on the top of the top cover 10. The liquid injection hole 2 is used for injecting lubricating oil. A sealing plug 20 is inserted and fitted in the liquid injection hole 2 for sealing operations. A plug cover 21 is fixedly installed on the top of the sealing plug 20. A lifting handle 22 is integrally formed on the side surface of the plug cover 21, which makes it smoother to open the plug cover 21 by lifting the handle 22.

[0031] It should be noted that a wire passing hole 3 is provided on the side plate body of the servo motor main body 1. A wire fixing seat 30 is arranged in the wire passing hole 3. The wire fixing seat 30 includes a wire passing sleeve 301 fixedly installed on the hole wall of the wire passing hole 3. A through hole 302 communicating with the outside is arranged in the wire passing sleeve 301. Side fixing stickers 303 are fixedly installed at both ends of the wire passing sleeve 301. The two side fixing stickers 303 are respectively fixedly installed on the inner and outer side surfaces of the servo motor main body 1, so that the cable can be passed through the through hole 302 for wiring operations. In addition, the part where the cable passes through the through hole 302 can be adhesively bonded to the hole wall of the through hole 302 with waterproof glue to prevent the lubricating oil from flowing out.

[0032] When the multi-layer distributed transmission type servo motor gear of the present utility model is in use, the sealing plug 20 is opened, and lubricating oil is added into the servo motor main body 1 from the liquid injection hole 2 for lubrication operations. After the fixed support 19 is fixedly installed at the corresponding position with fastening screws and used, when vibration occurs, along with the downward extrusion force generated at the servo motor main body 1 acting on the bottom shock pad 14, the triangular cushion block 15 and the fixed cushion block 16, the bottom shock pad 14, the triangular cushion block 15 and the fixed cushion block 16 can absorb this part of the force to achieve shock absorption.

[0033] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
