Description

Technical Field

[0001] The present invention relates to the technical field of reducer installation, and particularly to an inverted impact-resistant installation structure for a helical gear reducer. Background Technique

[0002] A helical gear reducer is a mechanical device that utilizes the principle of helical gear transmission. It is mainly used to reduce the speed of an electric motor and other power sources while increasing the output torque. Its structural feature is that there is a certain angle between the tooth surface of the gear and the rotating shaft. Compared with spur gears, helical gears have a larger contact area during meshing, operate more smoothly, produce lower noise, and have a stronger load-bearing capacity. The inverted impact-resistant installation structure of a helical gear reducer mainly refers to installing the helical gear reducer in an inverted manner in a specific application to meet the space requirements and operating conditions of the equipment. Inverted installation can not only effectively save space but also enhance the impact resistance of the equipment, ensuring that the reducer can withstand large power and impact forces during operation.

[0003] Currently, helical gear reducers are mostly used in the mechanical field. When there is limited space in the layout of mechanical equipment, in order to save space, it is often necessary to install the helical gear reducer in an inverted manner to meet the requirements of the overall structure and shape design. However, the front of the inverted-installed helical gear reducer is all downward. During the operation of the helical gear reducer, lubricating oil is required to form an oil film to reduce the direct contact between gears, lower the friction coefficient, thereby reducing wear and extending the service life of the gears and the reducer. Therefore, during the use of the helical gear reducer, in order to ensure the stability of the oil level in the helical gear reducer, the staff needs to regularly observe the oil level of the helical gear reducer. However, due to the special position of the inverted helical gear reducer and mostly being inverted and enclosed, it is inconvenient for the staff to observe the oil level of the helical gear reducer. The existing installation structures of helical gear reducers mostly only have the ability to resist impact and do not have the function of automatically adding oil level, which is likely to cause damage to the helical gear reducer due to insufficient oil level and insufficient lubrication.

[0004] Therefore, we propose an inverted impact-resistant installation structure for a helical gear reducer to solve the problems raised above. Summary of the Invention

[0005] The purpose of the present invention is to provide an inverted impact-resistant installation structure for a helical gear reducer to solve the problem that most of the installation structures of inverted helical gear reducers do not have the function of automatically adding oil level, which is likely to cause damage to the helical gear reducer due to insufficient lubrication as described in the above background technique.

[0006] To achieve the above object, the present invention provides the following technical solution: An inverted impact-resistant installation structure for a helical gear reducer, comprising an impact-resistant component and a helical gear reducer main body. An adding component is arranged on the outer surface of the impact-resistant component near one side edge. The adding component includes a storage tank for storing lubricating oil. A piston is arranged inside the storage tank for pushing the lubricating oil to be conveyed into the helical gear reducer main body.

[0007] Preferably, the adding component further includes a compression-resistant frame. A cylinder is arranged on the outer surface of the compression-resistant frame. One end of the cylinder is fixedly connected to the outer surface of the piston.

[0008] Preferably, one end of the cylinder movably penetrates into the storage tank. One end of the storage tank is fixedly communicated with a conveying pipe. A one-way valve is arranged on the outer surface of the conveying pipe.

[0009] Preferably, an installation frame is arranged on the outer surface of the impact-resistant component. A camera is arranged on the inner wall of the installation frame. The helical gear reducer main body includes a motor.

[0010] Preferably, a reducer body is arranged at the output end of the motor. An oil liquid limit hole is arranged on one side outer surface of the reducer body. An oil filling hole is opened on the other side outer surface of the reducer body.

[0011] Preferably, the impact-resistant component includes a bottom plate. A plurality of dampers are arranged on the outer surface of the bottom plate. Springs are arranged on the outer surfaces of the plurality of dampers. An impact-resistant plate is fixed between one ends of the plurality of dampers. One ends of the plurality of springs are fixedly connected to the outer surface of the bottom plate. The other ends of the plurality of springs are fixedly connected to the outer surface of the impact-resistant plate.

[0012] Preferably, a shock-absorbing pad is arranged on the outer surface of the impact-resistant plate. A controller is arranged near the center of the outer surface of the bottom plate. The outer surface of the storage tank is fixedly connected to the outer surface of the impact-resistant plate through screws.

[0013] Preferably, the outer surface of the compression-resistant frame is fixedly connected to the outer surface of the impact-resistant plate. One end of the conveying pipe fixedly penetrates into the oil filling hole. One side outer surface of the installation frame is fixedly connected to the outer surface of the impact-resistant plate.

[0014] Preferably, a cleaning component is arranged on the other side outer surface of the installation frame. The cleaning component includes a support plate. The outer surface of the support plate is fixedly connected to the outer surface of the installation frame. A driving motor is fixedly installed on the outer surface of the support plate through screws.

[0015] Preferably, a driving shaft is fixed at the output end of the driving motor. The two ends of the driving shaft respectively movably penetrate to the opposite outer parts of the support plate. A cleaning block is fixed at one end of the driving shaft.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. During the process of the motor driving the reducer body to operate, the camera is turned on to take pictures of the lubricating oil level in the oil level limiting hole. When the lubricating oil level in the oil level limiting hole is insufficient, the lubricating oil in the storage tank is conveyed outward into the inside of the fuel filling hole to lubricate the inside of the reducer body until the lubricating oil quantity in the oil level limiting hole reaches the required value, solving the problem in the prior art that the installation structures of most inverted helical gear reducers do not have the function of automatically adding oil level and are prone to damage the helical gear reducer due to insufficient lubrication.

[0017] 2. When it is necessary to install the helical gear reducer in an inverted manner, the helical gear reducer body is shock-absorbed by the shock pads. When the reducer body is impacted externally, it will first move towards the bottom plate, causing multiple springs to be compressed and shortened. Then, the multiple springs will elongate under the action of their own elastic forces, driving the shock-resistant plate to reset, thereby driving the reducer body to reset, further improving the seismic resistance of the inverted helical gear reducer.

[0018] 3. In order to maintain the cleanliness of the surfaces of the camera and the oil level limiting hole and improve the accuracy of camera detection, the drive motor is started to drive the cleaning block to rotate between the outer surfaces of the camera and the oil level limiting hole, so that the front and back sides of the cleaning block clean the surfaces of the camera and the oil level limiting hole respectively, further improving the accuracy of lubricating oil addition in the inverted helical gear reducer by the shock-resistant installation structure.

Specific embodiments

[0021] 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.

[0022] Please refer to Figures 1 - 4 and Figure 7 The present invention provides a technical solution: An installation frame 4 is arranged on the outer surface of the impact-resistant component 1, a camera 5 is arranged on the inner wall of the installation frame 4, the helical gear reducer main body 2 includes a motor 201, a reducer body 202 is arranged at the output end of the motor 201, an oil level limiting hole 203 is arranged on the outer surface of one side of the reducer body 202, an oil filling hole 204 is opened on the outer surface of the other side of the reducer body 202, the impact-resistant component 1 includes a bottom plate 101, a plurality of dampers 102 are arranged on the outer surface of the bottom plate 101, springs 103 are arranged on the outer surfaces of the plurality of dampers 102, an impact-resistant plate 104 is fixed between one ends of the plurality of dampers 102, one ends of the plurality of springs 103 are fixedly connected to the outer surface of the bottom plate 101, the other ends of the plurality of springs 103 are fixedly connected to the outer surface of the impact-resistant plate 104, a shock-absorbing pad 105 is arranged on the outer surface of the impact-resistant plate 104, a controller 106 is arranged near the center of the outer surface of the bottom plate 101, and the outer surface of the storage tank 301 is fixedly connected to the outer surface of the impact-resistant plate 104 through screws.

[0023] In this embodiment, when the helical gear reducer needs to be installed upside down, first, the main body 2 of the helical gear reducer is fixedly installed on the outer surface of the compression-resistant frame 302 through screws, and the main body 2 of the helical gear reducer is shock-absorbed by the shock-absorbing pad 105. Among them, the shock-absorbing pad 105 is made of polyurethane material. The polyurethane material has good mechanical properties and wear resistance, and can maintain good shock-absorbing effects under large loads. When the helical gear reducer encounters a large impact, it can play a certain shock-absorbing role for the helical gear reducer. In addition, in order to further improve the impact resistance of the reducer body 202, when the reducer body 202 is subjected to an external impact, it will first move towards the bottom plate 101, causing the plurality of springs 103 to be compressed and shortened. Then, the plurality of springs 103 will elongate under the action of their own elastic forces, driving the impact-resistant plate 104 to reset, thereby driving the reducer body 202 to reset, improving the impact resistance of the reducer body 202. Through the impact-resistant treatment of the installation structure of the helical gear reducer, the seismic resistance of the upside-down helical gear reducer is further improved.

[0024] As Figures 1 - 8 shown, an impact-resistant installation structure for upside-down helical gear reducer includes an impact-resistant component 1 and a helical gear reducer main body 2. An adding component 3 is arranged on the outer surface of the impact-resistant component 1 near one side edge. The adding component 3 includes a storage tank 301 for storing lubricating oil. A piston 304 is arranged inside the storage tank 301 for pushing the lubricating oil to be conveyed into the helical gear reducer main body 2. The adding component 3 further includes a compression-resistant frame 302. A cylinder 303 is arranged on the outer surface of the compression-resistant frame 302. One end of the cylinder 303 is fixedly connected to the outer surface of the piston 304, and one end of the cylinder 303 movably penetrates into the storage tank 301. One end of the storage tank 301 is fixedly communicated with a conveying pipe 305. A one-way valve 306 is arranged on the outer surface of the conveying pipe 305. An installation frame 4 is arranged on the outer surface of the impact-resistant component 1. A camera 5 is arranged on the inner wall of the installation frame 4. The helical gear reducer main body 2 includes a motor 201. The output end of the motor 201 is provided with a reducer body 202. An oil liquid limit hole 203 is arranged on one side outer surface of the reducer body 202, and an oil filling hole 204 is opened on the other side outer surface of the reducer body 202.

[0025] In this embodiment, in order to facilitate the addition of lubricating oil to the upside-down installed helical gear reducer, during the process of the motor 201 driving the reducer body 202 to operate, the camera 5 is first turned on through the controller 106. Among them, as Figure 7As shown in the figure, the camera 5 is installed at a position directly facing the oil level limiting hole 203, and the lubricating oil level in the oil level limiting hole 203 is photographed by the camera 5. Among them, the working principle of the camera 5 is as follows: the camera 5 regularly photographs the surface of the oil level limiting hole 203 to obtain a real-time image, and then transmits the obtained image to an image analysis software for processing. The software uses image processing technology to analyze the color, transparency, turbidity, etc. of the oil, extracts the features in the image to judge the quality of the oil, sets the quality parameters of the lubricating oil according to industry standards, and then compares the extracted features with the preset standards through the software to judge whether the lubricating oil volume in the oil level limiting hole 203 meets the standard. When the camera 5 photographs that the lubricating oil level in the oil level limiting hole 203 is insufficient, a signal can be transmitted to the controller 106, and the cylinder 303 is started through the controller 106 to make it extend, driving the piston 304 to move forward, so as to convey the lubricating oil stored in the storage tank 301 outward, so that the lubricating oil enters the inside of the conveying pipe 305, passes through the one-way valve 306 and enters the inside of the oil filling hole 204, lubricates the inside of the reducer body 202 by adding oil to the box, and the added amount of lubricating oil is displayed through the oil level limiting hole 203. When the camera 5 photographs that the lubricating oil volume displayed in the oil level limiting hole 203 reaches the required value, a signal can be transmitted to the controller 106, and the cylinder 303 is closed through the controller 106 to stop squeezing the piston 304, that is, the automatic addition of lubricating oil in the helical gear reducer is completed. Among them, through the setting of the one-way valve 306, the lubricating oil in the oil filling hole 204 is effectively prevented from flowing back into the inside of the storage tank 301, solving the problem that the installation structure of most inverted helical gear reducers in the prior art does not have the function of automatically adding oil level, which easily causes the helical gear reducer to be damaged due to insufficient lubrication.

[0026] As Figures 1 - 4 and Figure 8 As shown in the figure, an installation frame 4 is arranged on the outer surface of the impact-resistant component 1, a camera 5 is arranged on the inner wall of the installation frame 4, the helical gear reducer main body 2 includes a motor 201, a cleaning component 6 is arranged on the outer surface of the other side of the installation frame 4, the cleaning component 6 includes a support plate 601, the outer surface of the support plate 601 is fixedly connected with the outer surface of the installation frame 4, a driving motor 602 is fixedly installed on the outer surface of the support plate 601 through screws, a driving shaft 603 is fixed to the output end of the driving motor 602, both ends of the driving shaft 603 respectively penetrate through the opposite outer parts of the support plate 601 movably, and a cleaning block 604 is fixed to one end of the driving shaft 603.

[0027] In this embodiment, in order to maintain the cleanliness of the surface of the camera 5 and the oil level limiting hole 203 and improve the accuracy of the detection by the camera 5, the drive motor 602 is started by the controller 106 to drive the drive shaft 603 to rotate, and then drive the cleaning block 604 to rotate between the outer surfaces of the camera 5 and the oil level limiting hole 203, so that the front and back surfaces of the cleaning block 604 clean the surfaces of the camera 5 and the oil level limiting hole 203 respectively. Among them, combined with Figures 1 - 2 As shown, the cleaning block 604 is arranged between the outer surfaces of the camera 5 and the oil level limiting hole 203, and the cleaning block 604 is made of sponge material and has a strong cleaning effect. Through the action of the cleaning component 6, the accuracy of lubricating oil addition in the inverted helical gear reducer of the shock-resistant mounting structure is further improved.

[0028] Usage method and working principle of this device: When the helical gear reducer needs to be installed upside down, first fix and install the helical gear reducer main body 2 on the outer surface of the compression-resistant frame 302 through screws, and perform shock absorption treatment on the helical gear reducer main body 2 through the shock absorption pad 105. When the helical gear reducer encounters a large impact, it can play a certain shock absorption effect on the helical gear reducer. In addition, in order to further improve the shock resistance of the reducer main body 202, when the reducer main body 202 is externally impacted, it will first move in the direction of the bottom plate 101, causing the plurality of springs 103 to be compressed and shortened. Then, the plurality of springs 103 will elongate under the action of their own elastic force, driving the shock-resistant plate 104 to reset, thereby driving the reducer main body 202 to reset, improving the shock resistance of the reducer main body 202. In order to facilitate the addition of lubricating oil in the upside-down installed helical gear reducer, during the process of the motor 201 driving the reducer main body 202 to operate, first open the camera 5 through the controller 106, as Figure 7As shown, the camera 5 is installed at a position directly opposite to the oil level limiting hole 203. By taking pictures of the lubricating oil level in the oil level limiting hole 203 through the camera 5, it is determined whether the amount of lubricating oil in the oil level limiting hole 203 meets the standard. When the camera 5 captures that the lubricating oil level in the oil level limiting hole 203 is insufficient, a signal can be transmitted to the controller 106. Through the controller 106, the cylinder 303 is started to make it extend, driving the piston 304 to move forward, so as to convey the lubricating oil stored in the storage tank 301 outward. The lubricating oil enters the interior of the conveying pipe 305, passes through the one-way valve 306 and enters the interior of the fueling hole 204, lubricates the interior of the reducer body 202 by adding oil to the box, and the amount of lubricating oil added is displayed through the oil level limiting hole 203. When the camera 5 captures that the amount of lubricating oil displayed in the oil level limiting hole 203 reaches the required value, a signal can be transmitted to the controller 106. Through the controller 106, the cylinder 303 is closed to stop squeezing the piston 304, that is, the automatic addition of lubricating oil in the helical gear reducer is completed. In addition, the driving motor 602 is regularly started through the controller 106 to drive the driving shaft 603 to rotate, and then drive the cleaning block 604 to rotate between the outer surfaces of the camera 5 and the oil level limiting hole 203, so that the front and back sides of the cleaning block 604 clean the surfaces of the camera 5 and the oil level limiting hole 203 respectively. Among them, the controller 106 is electrically connected to the motor 201, the cylinder 303, the camera 5 and the driving motor 602.

[0029] The wiring diagrams of the controller 106, the motor 201, the cylinder 303, the camera 5 and the driving motor 602 in the present invention belong to the common knowledge in the art. Their working principles are already known technologies, and their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the controller 106, the motor 201, the cylinder 303, the camera 5 and the driving motor 602 will not be explained in detail.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
