Description

Technical Field

[0001] The present invention relates to the technical field of reduction motors, and in particular to a dual-shaft reduction motor with high-intensity output. Background Art

[0002] When selecting drive motors for many high-strength reducers, in order to ensure the efficient and safe operation of the reducer, it is necessary to select drive motors that match the high-strength parameter specifications. However, when the drive motor is running at high speed and under high load, it is easy to vibrate strongly, which not only causes greater noise pollution to the production environment, but also long-term high-intensity vibration will have an adverse effect on the stable operation of the drive motor.

[0003] In order to solve the above problems, some workshops install a soundproof cover around these motors with high vibration intensity and noise, trying to reduce the noise impact of the motor on the surrounding production environment. Although this method reduces the noise impact of the motor on the surrounding production environment, it is not conducive to heat dissipation, and the vibration of the motor itself is completely "digested" by the click, without other carriers to effectively alleviate the vibration of the motor, which is not conducive to the high-intensity and long-term stable operation of the motor.

[0004] Therefore, when the drive motor is used in output devices such as load-intensive output reducers, it becomes a problem to reduce the high-intensity vibration generated by the drive motor, reduce the production environment noise around the drive motor, and ensure the long-term stable operation of the drive motor under high-intensity load conditions. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a dual-axis reduction motor with high-intensity output, so that when the drive motor is used with output devices such as high-intensity reducers, the high-intensity vibration caused by the drive motor and the noise to the surrounding production environment are reduced, thereby ensuring long-term stable operation of the drive motor under high-intensity load conditions.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

The bottom of the drive motor is provided with a motor bottom plate integrally formed with the drive motor, and the bottom side of the motor bottom plate is provided with a plurality of lower card cones distributed in array positions. The motor bottom plate is embedded and installed at the top side of a motor base, and an inner cavity is provided in the motor base, and the inner cavity of the motor base is filled with porous filling materials, and a plurality of insert slots are prefabricated in the porous filling material area. An air pipe connected to the inner cavity of the motor base is provided on one side of the motor base, and a pipe valve is arranged at the outer end of the air pipe, and a barometer for monitoring the air pressure in the inner cavity of the motor base is installed on the air pipe, wherein, during the use of the drive motor, the air pressure value in the inner cavity of the motor base is not lower than Natm, N≥2.

[0008] The motor base is provided with a lower notch and an upper notch located above its inner cavity. A high-density alloy part is sealed and installed at the position of the lower notch. A plurality of upper conical grooves distributed in an array are opened on the top side of the high-density alloy part. A plurality of alloy inserts are provided on the bottom side of the high-density alloy part. The alloy inserts are inserted into the insert grooves in the porous filling material area. The motor base plate is installed at the position of the upper notch, and a damping gasket is sandwiched between the motor base plate and the upper notch.

[0009] The multiple lower clamping cones of the motor base plate are extruded and installed one by one at the multiple upper cone groove positions of the high-density alloy part. A fixed clamping strip plate for clamping and fixing the motor base plate is fixedly installed on the top side of the motor base, and an upper damping pad is sandwiched between the fixed clamping strip plate and the motor base plate.

[0010] As a preferred technical solution of the present invention: a plurality of locking grooves are provided on the top side of the motor base plate, a plurality of locking protrusions are provided on the bottom side of the fixed clip plate, an upper damping pad is provided with an upper hole matching the locking protrusions, the locking protrusions pass through the upper hole and are snap-fitted and installed at the position of the locking grooves.

[0011] As a preferred technical solution of the present invention: the vertical length of the alloy insert is the same as the insert slot depth of the porous filling material area. Let the vertical height of the porous filling material area be Ha, and let the insert slot depth be Hc, then 0.5Ha <Hc<0.8Ha。

[0012] As a preferred technical solution of the present invention: a retaining notch surrounding the high-density alloy part is provided at the ring side of the high-density alloy part, a sealing ring is arranged at the lower notch position, and the retaining notch of the high-density alloy part is extruded and sealed with the sealing ring.

[0017] The present invention embeds a motor bottom plate at a position of a motor base with a relatively low material density, configures a high-density alloy part with a relatively high material density, and configures a porous filling material in the inner cavity of the motor base, so that the alloy insert of the high-density alloy part is in full contact with the porous filling material, and at the same time increases the air pressure in the porous filling material area, so that the porous filling material can quickly "drain" and "evenly distribute" the vibration intensity, thereby improving the vibration release effect of the alloy insert. This reduces the high-intensity vibration caused by the drive motor and the noise to the surrounding production environment when the drive motor is used with output devices such as a high-intensity reducer under load, thereby ensuring long-term stable operation of the drive motor under high-intensity load conditions.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] Embodiment 1: The present invention relates to a dual-axis reduction motor with high output strength. Figure 1 , Figure 2 , Figure 3 , mainly including a driving motor 1, a dual-axis output reduction box 2, a motor base plate 101, a motor base 3, a porous filling material 4 filled in the motor base 3, a high-density alloy part 7 and other related components are arranged at the bottom of the driving motor 1, and the specific structural contents are as follows:

[0029] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 The motor base plate 101 is located at the bottom of the driving motor 1. The motor base plate 101 and the driving motor 1 are an integrally formed structure. A plurality of lower cones 102 are arranged. The plurality of lower cones 102 are arranged in an array position on the bottom side of the motor base plate 101. The motor base plate 101 is embedded and installed at the top side of a motor base 3.

[0030] See also Figure 2 , Figure 4 , Figure 7 The inner circle of the motor base 3 is an inner cavity, and the inner cavity of the motor base 3 is filled with porous filling material 4. The porous filling material 4 has the effect of damping and absorbing vibration. The vibration transmitted to the inner cavity of the motor base 3 is absorbed by the porous filling material 4, and the vibration intensity is greatly attenuated. The porous filling material 4 area is prefabricated with multiple insert slots 401.

[0031] The porous filling material 4 can be made of porous magnesium alloy foam, which has the characteristics of light weight and high specific strength, and has multiple physical properties such as porosity, vibration reduction, damping, sound absorption, sound insulation, heat dissipation, impact energy absorption, electromagnetic shielding, etc. According to the actual maximum load of the drive motor 1, a porous filling material with corresponding pore specifications can be designed to meet the stable operation requirements of the drive motor 1.

[0032] See also Figure 2 , Figure 3 One side of the motor base 3 is provided with an air pipe 304 connected to its inner cavity, and the outer end of the air pipe 304 is provided with a pipe valve 305, which can be connected to a flexible "inflating" device pipeline outside to inflate the inner cavity of the motor base 3 to increase the air pressure in the inner cavity of the motor base 3. The increase in the air pressure in the inner cavity of the motor base 3 actually means that the gas density in the inner cavity increases rapidly, which greatly improves the effect of vibration transmission in the porous filling material 4 area. Originally, when the alloy insert 701 releases the vibration intensity, only the porous filling material near the surface of the alloy insert 701 can absorb some Vibration, after increasing the air pressure in the inner cavity, the gas density increases significantly, so that the vibration can be quickly diffused in the porous filling material 4 area in the inner cavity, releasing the "large amount" of vibration intensity absorbed by the local porous filling material near the surface of the alloy insert, avoiding the local porous filling material 4 near the surface of the alloy insert 701 due to the real-time absorption and accumulation of vibration intensity, which interferes with and inhibits the release of vibration intensity on the alloy insert 701. In fact, the porous filling material in the high-pressure environment improves the vibration release effect of the alloy insert 701 by "draining" and "averaging" the vibration intensity. A barometer 306 for monitoring the air pressure in the inner cavity of the motor base 3 is also installed on the air pipe 304. The inspection personnel can regularly check the air pressure value of the barometer 306, or when the noise of the drive motor 1 is large, check the air pressure value of the barometer 306 in time. In the process of using the drive motor 1, the air pressure value of the inner cavity of the motor base 3 is not lower than Natm, N≥2.

[0033] Among them, the material density of the motor base 3, the material density of the motor base plate 101, and the material density of the high-density alloy part 7 increase in sequence. The greater the density, the better the vibration transmission effect. For example, the motor base 3 is made of aluminum alloy (the density of aluminum alloy is 2.63 - 2.85 g / cm³), while the motor base plate 101 is made of cast copper alloy (the density of cast copper alloy is 8.67 g / cm³), and the high-density alloy part 7 is made of copper alloy. When economic conditions permit, the high-density alloy part 7 is made of tungsten alloy (the density of tungsten alloy is 17.0 - 18.5 g / cm³). In order to transfer as much vibration intensity as possible through the high-density alloy part to the inside of the porous filling material, a motor base 3 with a low density is required to reduce the vibration intensity absorbed by the motor base 3 and released to the outside, and enhance the vibration intensity absorbed by the high-density alloy part 7 and released to the inside of the porous filling material 4.

[0034] Please refer to Figure 2 、 Figure 4 、 Figure 6 、 Figure 7 The motor base 3 is provided with a lower notch 301 and an upper notch 302. The lower notch 301 and the upper notch 302 are located above the inner cavity of the motor base 3. For the upper notch 302, the high-density alloy part 7 is installed at the position of the lower notch 301 and is correspondingly equipped with a seal. A plurality of upper tapered grooves 703 are formed on the top side of the high-density alloy part 7, and the plurality of upper tapered grooves 703 are distributed in an array. A plurality of alloy inserts 701 are provided at the bottom side of the high-density alloy part 7, and the alloy inserts 701 are inserted into the insert grooves 401 in the area of the porous filling material 4. The vertical length of the alloy inserts 701 is the same as the groove depth of the insert grooves 401 in the area of the porous filling material 4.

[0035] In addition, let the longitudinal height of the area of the porous filling material 4 be Ha, and let the groove depth dimension of the insert groove 401 be Hc. Then 0.5Ha < Hc < 0.8Ha. If the insert groove 401 is too shallow, the length of the alloy inserts 701 inserted into the porous filling material 4 is small, and the vibration transmission area range is small, which is not conducive to the rapid diffusion of vibration in the porous filling material 4. The insert groove 401 cannot be too deep either. A part of the porous filling material 4 needs to be left at the bottom for lateral vibration transmission and absorption at different positions.

[0036] Please refer to Figure 2 、 Figure 4 、 Figure 7 The top side of the motor base 3 is fixedly installed with a fixed clamping strip plate 9, and the fixed clamping strip plate 9 is used to clamp and fix the motor base plate. In addition, a layer of upper damping cushion plate 8 is clamped between the fixed clamping strip plate 9 and the motor base plate 101 to further isolate and absorb vibration. The motor base plate 101 is installed at the position of the upper notch 302, and a layer of damping washer 6 is also installed between the motor base plate 101 and the upper notch 302.

[0037] Both the fixed card strip plate 9 and the motor base 3 are provided with vertical through holes, and the vertical through holes of the two penetrate each other. A nut mounting groove for installing a nut is provided on the side of the motor base 3, and the nut mounting groove is connected with the through hole vertically penetrating the motor base 3. The nut is placed in the nut mounting groove and aligned with the through hole, and then the bolt is installed from top to bottom and tightened. The through hole structure is not specifically drawn in the present invention, but it does not affect the realization of this feature point.

[0038] See also Figure 4 , Figure 6 , Figure 7 The high-density alloy part 7 is provided with a circle of positioning notches 702 at the ring side, and the sealing ring 5 is installed in cooperation at the position of the lower notch 301, and the positioning notch 702 of the high-density alloy part 7 is pressed and sealed with the sealing ring 5. The damping washer 6 is divided into a lower damping ring 601 at the lower side and an upper damping ring 602 at the upper side, the motor bottom plate 101 is pressed and contacted with the upper damping ring 602, and the lower damping ring 601 is pressed and contacted with the high-density alloy part 7.

[0039] See also Figure 2 , Figure 3 , Figure 5 The multiple lower cones 102 of the motor base plate 101 are extruded and installed one by one at the positions of the multiple upper cone grooves 703 of the high-density alloy part 7. A relatively tight extrusion contact is formed between the bottom side of the motor base plate 101 and the multiple lower cones 102 and the high-density alloy part 7, thereby efficiently completing the vibration transmission.

[0040] See also Figure 3 , Figure 4 , Figure 5 , Figure 8 A plurality of latching grooves 103 are provided on the top side of the motor base plate 101, a plurality of latching protrusions 901 are located on the bottom side of the fixed clip plate 9, and a plurality of upper holes 801 are provided on the upper damping pad 8. The upper holes 801 are aligned with the latching protrusions 901, and the latching protrusions 901 pass through the upper holes 801 and are latched and installed at the position of the latching grooves 103.
