Description

Technical Field

[0001] This utility model belongs to the field of motor technology, specifically relating to a throttle servo motor. Background Technology

[0002] Servo motors can control speed and position with extremely high accuracy. They can convert voltage signals into torque and speed to drive the controlled object. The rotor speed of a servo motor is controlled by the input signal and can respond quickly. In automatic control systems, they are used as actuators and have characteristics such as a small electromechanical time constant and high linearity. They can convert received electrical signals into angular displacement or angular velocity output on the motor shaft. Servo motors are used in various industries, such as in excavators.

[0003] The throttle servo motor used in excavators consists of a mounting plate and a housing. The housing houses various components such as the spindle, turbine, circuit board, and sensors. The housing is fixed to the mounting plate with bolts, and the mounting plate is fixed to other components with bolts. Excavators are typically used in construction sites, mountainous areas, and other similar environments, which generates vibrations during operation. The servo motor also generates vibrations during operation. Over time, the bolts on the housing and mounting plate may gradually loosen due to vibration, affecting the normal operation of the servo motor and the entire excavator. In severe cases, this could lead to safety accidents. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a throttle servo motor in which the bolts are not easily loosened during use.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a throttle servo motor, including a mounting plate and a housing fixed on the mounting plate. The mounting plate has a protrusion on the surface facing the housing, and an elastic part made of elastic material is wrapped on the protrusion. The side of the elastic part facing the mounting plate abuts against the mounting plate, and the side of the elastic part facing the housing abuts against the housing.

[0006] By adopting the above solution, the elastic part can reduce the amplitude and frequency of relative displacement between the mounting plate and the housing during the use of this utility model. The protrusion can prevent the elastic part from moving along the extension direction of the mounting plate. The independent setting of the elastic part facilitates the replacement of a new elastic part after irreversible deformation occurs.

[0007] Compared with existing technologies, the bolts used for fixing in this utility model are less prone to loosening, and the elastic part has a certain shock absorption effect, ensuring the normal use of this utility model and the normal use of the entire machine.

[0008] Preferably, the outer wall of the elastic part is frosted, and the maximum distance from the elastic part to the mounting plate is 1.2 to 1.5 times the maximum distance from the protrusion to the mounting plate.

[0009] As a further feature of this utility model, there are multiple protrusions. The cross-section of each protrusion along the direction parallel to its own surface is elongated, and the cross-section along the direction perpendicular to its own surface is composed of a square and arcs less than or equal to semicircles arranged on opposite sides of the square. The elastic part has a fixing groove on the surface facing the mounting plate that is complementary to the shape of the protrusion.

[0010] Using the above solution, the surface of the protrusion refers to the surface of the mounting plate facing the housing, which allows the protrusion to be better fixed relative to the mounting part, facilitating the replacement of the elastic part later.

[0011] As a further feature of this invention, the protrusion has multiple spherical crown shapes that are larger than hemispheres, and the elastic part has a fixing groove on the surface facing the mounting plate that is complementary to the shape of the protrusion.

[0012] The above solution allows the protrusion to be better fixed relative to the mounting part, making it easier to replace the elastic part later.

[0013] As a further feature of this invention, the mounting plate is provided with a plurality of polygonal grooves of the same shape, each groove being surrounded by a plurality of protrusions, adjacent grooves sharing a common protrusion, and adjacent protrusions being connected to each other or having gaps between them.

[0014] By adopting the above scheme, all the protrusions are arranged in a certain pattern, allowing them to better support the elastic part. The grooves ensure heat dissipation of this invention.

[0015] As a further feature of this invention, the groove is a regular hexagonal groove, the elastic part is integrally formed, and the elastic part is honeycomb shaped.

[0016] The above solution strengthens the elastic component, providing better shock absorption. While ensuring the elastic component maintains its function, it also reduces the contact area with the housing and mounting plate, thus ensuring heat dissipation.

[0017] As a further feature of this invention, the surface of the elastic part facing the housing is a curved surface or a plane that is complementary to the surface of the housing facing the mounting plate.

[0018] Using the above scheme, the surface of the shell facing the mounting plate may be an irregular curved surface or a flat surface. The shape of the surface of the elastic part facing the shell is complementary to the surface of the shell facing the mounting plate, so that the force on each part of the elastic part is more balanced.

[0019] The present invention will now be further described with reference to the accompanying drawings. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] Specific embodiments of this utility model are shown in the accompanying drawings.

[0027] A throttle servo motor includes a mounting plate 1 and a housing 2 fixed on the mounting plate 1. The mounting plate 1 has a protrusion 11 on the surface facing the housing 2. An elastic part 3 made of elastic material is wrapped on the protrusion 11. The side of the elastic part 3 facing the mounting plate 1 abuts against the mounting plate 1, and the side of the elastic part 3 facing the housing 2 abuts against the housing 2.

[0028] The elastic part 3 reduces the amplitude and frequency of relative displacement between the mounting plate 1 and the housing 2 during use in this embodiment. The protrusion 11 prevents the elastic part 3 from shifting along the extension direction of the mounting plate 1. The elastic part 3 is independently provided, which facilitates the replacement of a new elastic part 3 after irreversible deformation occurs.

[0029] Compared to existing technologies, the bolts used for fixing in this embodiment are less prone to loosening, and the elastic part 3 has a certain shock absorption effect, ensuring the normal use of this embodiment and the normal use of the entire machine.

[0030] In this embodiment, the outer wall of the elastic part 3 is frosted, and the maximum distance from the elastic part 3 to the mounting plate 1 is 1.3 times the maximum distance from the protrusion 11 to the mounting plate 1.

[0031] There are multiple protrusions 11. The cross-section of each protrusion 11 along the direction parallel to its own surface is elongated, and the cross-section along the direction perpendicular to its own surface is composed of a square and semicircles on opposite sides of the square. In this embodiment, the semicircles are located on the side of the square away from the mounting plate 1. The elastic part 3 has a fixing groove 31 on its surface facing the mounting plate 1 that complements the shape of the protrusion 11. This allows the protrusion 11 to be better fixed relative to the mounting part, facilitating the replacement of the elastic part 3 later.

[0032] In this embodiment, the mounting plate 1 has multiple hexagonal grooves 12 of the same shape. Each groove 12 is surrounded by six protrusions 11, and adjacent grooves 12 share a common protrusion 11. Adjacent protrusions 11 are interconnected. All protrusions 11 are arranged in a certain pattern, allowing them to better support the elastic part 3. The grooves 12 also ensure heat dissipation in this embodiment.

[0033] The elastic part 3 is integrally formed and has a honeycomb shape. This makes the elastic part 3 stronger and provides better shock absorption. While ensuring its function, the elastic part 3 has less contact area with the housing 2 and the mounting plate 1, thus ensuring heat dissipation.

[0034] In this embodiment, the surface of the housing 2 facing the mounting plate 1 is a plane, and the surface of the elastic part 3 facing the housing 2 is a plane complementary to the surface of the housing 2 facing the mounting plate 1. The shape of the surface of the elastic part 3 facing the housing 2 is complementary to the surface of the housing 2 facing the mounting plate 1, so that the force on each part of the elastic part 3 is more balanced.

[0035] This utility model is not limited to the specific embodiments described above. Those skilled in the art can implement this utility model using other specific embodiments based on the content disclosed in this utility model. Any simple changes or modifications made to the design structure and concept of this utility model will fall within the protection scope of this utility model.
