Description

Technical Field

[0001] The invention relates to the technical field of reducers, and in particular to a reducer housing made of high-strength material. Background Art

[0002] The reducer case is the basic component for installing each transmission shaft. It mainly includes the main case, the upper case cover and the reduction gear installed in the case. When in use, lubricating oil will be injected into the case to reduce the wear of the reduction gear meshing transmission. When the reducer is working, each shaft will generate a large reaction force when transmitting torque and act on the case. Therefore, it is necessary to ensure that the case has sufficient rigidity and strength to ensure the stability of the transmission link and maintain the accuracy of the relative position of each transmission shaft. The metal structure case made of cast iron material can obtain greater strength and rigidity.

[0003] The inner wall of the upper cover in the existing reducer housing is generally a horizontal surface or an arc surface. During the transmission process of the reduction gear inside the reducer housing, the rotation of the reduction gear will cause the lubricating oil in the housing to be thrown onto the inner wall of the housing cover. The lubricating oil thrown onto the inner wall of the housing cover drips back into the housing due to its own gravity and the vibration generated by the housing. The dripping speed is slow, and the lubricating oil is thrown onto the inner wall of the housing cover. When the subsequent maintenance personnel repair the reducer, the lubricating oil adhering to the inner wall of the cover is not easy to be handled, thereby increasing the workload of the maintenance personnel; Therefore, the present invention proposes a speed reducer housing made of high-strength material to compensate for and improve the deficiencies of the prior art.

Correspondingly, a one-way valve 1 is installed above the side of the air supply cylinder away from the cylindrical cylinder, the end of the air supply cylinder away from the cylindrical cylinder is connected to a pressure storage cylinder, a one-way valve 2 is installed at the connecting portion between the air supply cylinder and the pressure storage cylinder, the upper end of the pressure storage cylinder is connected to an air intake pipe, a pressure valve 1 is installed at the connection between the air intake pipe and the pressure storage cylinder, the end of the air intake pipe away from the pressure storage cylinder is connected to a liquid storage cylinder, the air intake pipe is connected to a pressure relief pipe, a sealing cover is threadedly connected to the upper end of the pressure relief pipe, a piston plate is slidably connected to the inside of the liquid storage cylinder, a spring 2 is arranged between the lower end of the piston plate and the liquid storage cylinder, the upper end of the liquid storage cylinder is connected to a conspicuous tube, a one-way control valve is installed on the conspicuous tube, the conspicuous tube adopts a transparent plastic hose, and a reminder liquid is placed inside the liquid storage cylinder.

[0006] Preferably, the overall shape of the barrier and drainage component is matched with the inner wall contour of the upper box cover, and the inner and outer surfaces of the barrier and drainage component are both provided with anti-stick coatings.

[0007] Preferably, the two extension portions on the same triangular portion are arranged obliquely and their lower ends are close to each other.

[0008] Preferably, the eye-catching tube is triangular in shape as a whole.

[0009] Preferably, the liquid storage cylinder is fixedly connected to the adjacent second side plate.

[0010] As a preferred embodiment, a responsive loss reduction oil replenishing mechanism is also included, which includes a branch pipe, a connecting pipe, an oil storage tank, a second pressure valve, an oil outlet pipe and an oil outlet branch pipe.

When the maintenance personnel check the reducer case on a daily basis and observe that the eye-catching tube is red, it means that the transmission parts inside the reducer case are worn, which makes it easier for the maintenance personnel to repair the reducer in a timely manner. When the reducer housing vibrates abnormally, before the maintenance personnel take timely action, the lubricating oil inside the oil storage tank can be dripped onto the connection between the shaft mounting part and the drive shaft, thereby achieving the lubrication effect in time to maintain the transmission stability of this part, while reducing the wear between the drive shaft and the shaft mounting part, and extending the service life of the reducer housing.

DETAILED DESCRIPTION

[0014] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] The present invention will be further described below in conjunction with the embodiments.

[0016] In the attached drawings of the present scheme description, the barrier drainage component 14 and the example reduction gear 1201 are only shown as one, but in the specific implementation, the example reduction gear 1201 and the barrier drainage component 14 are not limited to one, and the specific number needs to be adaptively set according to the number of other reduction components inside the main housing 1, that is, the installation positions of other reduction gears in the reducer housing, to ensure that a barrier drainage component 14 is correspondingly arranged above each reduction gear.

[0017] Embodiments of the present invention refer to Figures 1 to 11 A speed reducer housing made of high-strength material comprises a main housing 1 and an upper housing cover 11. A shaft mounting portion 12 is symmetrically arranged on one side of the main housing 1 and the upper housing cover 11 close to each other. The shaft mounting portion 12 is used to connect a transmission shaft, and the transmission shaft is used to install an example speed reduction gear 1201. The inner wall of the upper box cover 11 is provided with a blocking and drainage component 14, which is correspondingly arranged directly above the example reduction gear 1201. When the example reduction gear 1201 rotates, the lubricating oil on the outer wall of the example reduction gear 1201 can be reduced from being thrown to the inner wall of the upper box cover 11, thereby avoiding the problem that the lubricating oil cannot drip back to the inside of the main box body 1 in time, thereby improving the utilization effect of the lubricating oil; like Figures 1 to 6 As shown, the blocking and drainage component 14 is composed of a triangular portion 1401 and an extension portion 1402, and an extension portion 1402 is fixedly connected to both sides below the triangular portion 1401, and the middle position of the triangular portion 1401 and the connection portion with the extension portion 1402 are both chamfered and polished. The chamfered and polished treatment can reduce the adhesion of lubricating oil in a small space, avoid the situation that the subsequent treatment is difficult and the lubricating oil is difficult to drip back, and at the same time, through the cooperation of the triangular portion 1401 and the extension portion 1402, when the lubricating oil is thrown to the inner wall of the blocking and drainage component 14, the extension portion 1402 is used as a guide plate to drain the lubricating oil to the surface of the example reduction gear 1201, so as to prevent the lubricating oil from splashing out over a large area and adhering to the inner wall of the main box body 1 in a targeted manner; Specifically, the overall shape of the barrier and drainage component 14 is adapted to the inner wall contour of the upper box cover 11, and the inner and outer surfaces of the barrier and drainage component 14 are evenly provided with an anti-stick coating, which is made of polytetrafluoroethylene coating. The two extension portions 1402 on the same triangular portion 1401 are inclined and their lower ends are close to each other, facing the top of the example reduction gear 1201, so as to facilitate the drainage of the lubricating oil adhering to the inner wall of the extension portion 1402 to the top of the example reduction gear 1201.

[0018] like Figures 1 to 3 as well as Figures 7 to 10As shown, the outer wall of the upper box cover 11 is provided with a vibration feedback warning mechanism, which includes a first side plate 21 welded on the outer wall of one side of the upper box cover 11, and a second side plate 22 is symmetrically welded on the outer wall of the upper box cover 11, and a vibration sensor 25 is fixedly installed on the second side plate 22, and the position of the second side plate 22 corresponds to the position of the shaft mounting portion 12, and is located above the shaft mounting portion 12. The upper surface of the first side plate 21 is fixedly connected with a cylindrical tube 23 and an air supply tube 27, and an electric telescopic rod 24 is fixedly installed inside the cylindrical tube 23, and the electric telescopic rod 24 and the above-mentioned vibration sensor 25 are both electrically connected to an external known controller. The cylindrical tube 23 is a combined structure of upper and lower halves. The cylindrical tube 23 is divided into an upper part and a lower part, and the upper and lower parts of the cylindrical tube 23 are detachably connected, specifically by bolt fastening. The lower part of the cylindrical tube 23 is fixedly connected to the first side plate 21. The cylindrical tube 23 is used to protect the electric telescopic rod 24. At the same time, the detachable connection also makes it convenient for users to install and repair the electric telescopic rod 24.

[0019] A piston rod 26 is slidably connected inside the air supply cylinder 27. The piston rod 26 includes a rod body and a piston disk. The rod body and the piston disk are fixedly connected, wherein the piston disk is slidably connected inside the air supply cylinder 27. The rod body penetrates the air supply cylinder 27 and the cylindrical cylinder 23 and extends into the cylindrical cylinder 23. The position of the piston rod 26 corresponds to the position of the electric telescopic rod 24. The rod body is located on the horizontal movement path of the telescopic end of the electric telescopic rod 24. A one-way valve 2701 is installed above the side of the air supply cylinder 27 away from the cylindrical cylinder 23. The one-way valve 2701 is installed above the side of the air supply cylinder 27 away from the cylindrical cylinder 23. When valve 1 2701 is opened, the interior of the air supply cylinder 27 is connected with the outside world, and external gas can enter the interior of the air supply cylinder 27. A spring 1 is arranged between the side of the piston disk of the piston rod 26 away from the cylindrical cylinder 23 and the air supply cylinder 27. The end of the air supply cylinder 27 away from the cylindrical cylinder 23 is connected with a pressure accumulation cylinder 28. The pressure accumulation cylinder 28 is fixedly connected to the first side plate 21. A one-way valve 2 is installed at the connecting portion between the air supply cylinder 27 and the pressure accumulation cylinder 28. The gas inside the air supply cylinder 27 can enter the interior of the pressure accumulation cylinder 28 through the one-way valve 2.

[0020] The upper end of the pressure storage cylinder 28 is connected to an air intake pipe 2901, and a pressure valve 29 is provided at the connection between the air intake pipe 2901 and the pressure storage cylinder 28. The end of the air intake pipe 2901 away from the pressure storage cylinder 28 is connected to a liquid storage cylinder 210, and the liquid storage cylinder 210 is fixedly connected to the adjacent second side plate 22. The end of the air intake pipe 2901 close to the liquid storage cylinder 210 is connected to a pressure relief pipe 213, and a sealing cover is threadedly connected to the upper end of the pressure relief pipe 213. The interior of the liquid storage cylinder 210 is slidably connected to a piston plate 212, and a pressure relief pipe 213 is provided between the lower end of the piston plate 212 and the liquid storage cylinder 210. There is spring 2, and the upper end of the liquid storage cylinder 210 is connected to a conspicuous tube 211, and a one-way control valve is installed on the upper end of the conspicuous tube 211. Red reminder liquid is stored in the liquid storage cylinder 210. The red reminder liquid can be red ink, and the reminder liquid is located above the piston plate 212. When the reminder liquid enters the conspicuous tube 211, the gas in the conspicuous tube 211 can be discharged to the outside through the one-way control valve to ensure that the reminder liquid in the liquid storage cylinder 210 enters the conspicuous tube 211. The conspicuous tube 211 is triangular as a whole, and the conspicuous tube 211 is a transparent plastic hose.

[0021] Furthermore, if Figures 1 to 3 as well as Figures 7 to 11 As shown, the reducer housing made of high-strength material also includes a responsive loss reduction oil replenishing mechanism, which includes a branch pipe 31, a connecting pipe 32, an oil storage tank 33, a pressure valve 34, an oil outlet pipe 35 and an oil outlet branch pipe 36. An oil storage tank 33 is fixedly arranged on each second side plate 22, and the air inlet pipe 2901 is connected to the branch pipe 31. Each oil storage tank 33 is connected to the branch pipe 31 through the connecting pipe 32. The interior of the oil storage tank 33 is filled with lubricating oil, and one side of the oil storage tank 33 is provided with a lubricating oil injection port. The oil filling port is an oil outlet pipe 35 connected to the lower end of the oil storage tank 33, a pressure valve 34 is provided at the connection between the oil storage tank 33 and the oil outlet pipe 35, and an oil outlet branch pipe 36 is provided below the oil outlet pipe 35. The oil outlet branch pipe 36 is fixedly connected to the adjacent shaft mounting portion 12. Specifically, a groove corresponding to the oil outlet branch pipe 36 is provided on the portion of the shaft mounting portion 12 located on the upper box cover 11, and the oil outlet branch pipe 36 is fixedly connected in the groove, so that the lubricating oil can flow better to the surface of the transmission shaft installed at the shaft mounting portion 12 after being discharged.

[0022] The complete working principle and steps of the above embodiment are as follows: When in use, the upper box cover 11 is fastened to the upper surface of the main box body 1 by the staff through bolts. A blocking and drainage component 14 is correspondingly provided above each reduction gear inside the main box body 1, which can reduce the lubricating oil from being thrown to the inner wall of the upper box cover 11. When the lubricating oil is thrown to the inner wall of the blocking and drainage component 14, the extension part 1402 is used as a guide plate to drain the lubricating oil to the gear surface, thereby avoiding the situation that the subsequent treatment is difficult and the lubricating oil is not easy to drip back; When the vibration feedback warning mechanism is used: When the reducer housing is in use, if the gears, transmission shafts, bearing seats, bearings and other parts inside the main housing 1 are worn out during long-term use, the main housing 1 will experience continuous abnormal vibration during use. When the vibration reaches the monitoring range of the vibration sensor 25, the controller will control the telescopic end of the electric telescopic rod 24 to extend, causing the piston rod 26 to move toward the direction close to the pressure accumulator 28 and compress the spring 1. During this process, the one-way valve 2 at the connecting part of the air supply cylinder 27 and the pressure accumulator 28 is opened, and the one-way valve 1 2701 on the air supply cylinder 27 is closed, so that the air inside the air supply cylinder 27 is sent into the interior of the pressure accumulator 28. As the air inside the air supply cylinder 27 is sent into the interior of the pressure accumulator 28, the pressure accumulator 28 is caused to When the internal pressure exceeds the preset pressure value of pressure valve 29, pressure valve 29 opens, and the air inside the pressure accumulator 28 can be sent into the space below the piston plate 212 inside the liquid storage cylinder 210 through the air intake pipe 2901, so that the air introduced can push the piston plate 212 upward and stretch the spring 2. As the piston plate 212 moves upward, the reminder liquid above the piston plate 212 will be sent into the interior of the eye-catching tube 211. During the process, the air inside the eye-catching tube 211 is discharged from the one-way control valve, and the red liquid will fill the interior of the eye-catching tube 211. At this time, the eye-catching tube 211 will appear red throughout, and the eye-catching tube 211 is a triangle as a whole. When maintenance personnel perform daily maintenance and inspection work, they can timely observe the changes in the eye-catching tube 211.

[0023] When the maintenance personnel find that the eye-catching tube 211 is red, they first retract the telescopic end of the electric telescopic rod 24 through the external controller. As the telescopic end is retracted, the piston rod 26 is prompted to move to the side away from the pressure accumulator 28 and reset under the action of the rebound force of the spring 1. At this time, the one-way valve 2 at the connecting part of the air supply cylinder 27 and the pressure accumulator 28 is closed, and the one-way valve 1 2701 on the air supply cylinder 27 is opened, so that external gas can enter the interior of the air supply cylinder 27. Then the sealing cover at the upper end of the pressure release tube 213 is manually turned to release the air inside the liquid storage cylinder 210 and below the piston plate 212. The air in the liquid storage cylinder 210 will be discharged as the air is discharged, and the internal pressure of the liquid storage cylinder 210 will be reduced. Under the action of spring 2, the piston plate 212 will be pulled down and reset. During the downward movement of the piston plate 212, a negative pressure will be formed in the space above the piston plate 212 inside the liquid storage cylinder 210, thereby causing the eye-catching tube 211 made of a plastic hose to contract, thereby sucking the reminder liquid inside the eye-catching tube 211 back into the liquid storage cylinder 210. In this way, the reminder liquid can be delivered to the inside of the eye-catching tube 211 again to ensure that it has a continuous reminder effect.

[0024] Therefore, when the main box body 1 and the upper box cover 11 are in use and produce abnormal vibrations, the red triangular eye-catching tube 211 will give the staff a visual prompt. When the maintenance personnel conduct daily inspections of the reducer and observe that the eye-catching tube 211 turns red, it means that the transmission parts inside the reducer box are worn, which makes it easier for the maintenance personnel to carry out timely maintenance on the reducer.

[0025] When the loss reduction oil replenishment mechanism is used: At the same time, when the pressure valve 1 29 is opened, the air inside the pressure storage cylinder 28 is sent into the liquid storage cylinder 210 through the air inlet pipe 2901. Since the air inlet pipe 2901 is connected to the branch pipe 31, part of the air will be sent into the connecting pipe 32 through the branch pipe 31, and then sent into the oil storage tank 33 through the connecting pipe 32, thereby increasing the pressure inside the oil storage tank 33 and causing the pressure valve 2 34 to open, thereby causing the lubricating oil inside the oil storage tank 33 to be sent into the oil outlet pipe 35 through the pressure valve 2 34, and then sent into the oil outlet branch pipe 36 through the oil outlet pipe 35. The lubricating oil overflowing from the oil outlet branch pipe 36 will drip onto the outer wall of the connecting portion between the transmission shaft and the shaft mounting portion 12, thereby playing a lubricating role in the connecting portion between the shaft mounting portion 12 and the transmission shaft. Therefore, when the reducer housing vibrates abnormally, before the maintenance personnel take timely measures, the lubricating oil inside the oil storage tank 33 can be dripped onto the connection between the shaft mounting part 12 and the transmission shaft, thereby achieving the lubrication effect in time to maintain the stability of the transmission at this part, while reducing the wear between the transmission shaft and the shaft mounting part 12, and extending the service life of the reducer housing.

[0026] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
