Description

Technical Field

[0001] This utility model belongs to the field of speed reducer technology, and in particular relates to a vertical speed reducer with a bearing lubrication system. Background Technology

[0002] Vertical gearboxes with bearing lubrication systems are core devices specifically designed for vertical power transmission and are widely used in driving vertical pumps, mixers, and other machinery. Due to their vertical structure, gravity causes the lubricating oil to sink naturally, making the bearings located at the top of the gearbox highly susceptible to damage due to lack of lubrication. Therefore, a specially designed and reliable lubrication system is crucial for their stable operation. There are two main lubrication methods: one is splash lubrication, which is simple in structure and low in cost, relying on rotating parts to splash oil for lubrication, but it is only suitable for small, light-load applications; the other is a forced lubrication system used in medium to large, heavy-load equipment. This system precisely and continuously delivers lubricating oil to each bearing point through an oil pump, oil lines, and distributor. However, vertical gearboxes still have the following drawbacks in practical use: When a vertical reducer is in operation, the lubricating oil needs to be changed as the work progresses. When changing the lubricating oil, a circulating pump is also needed to pump the oil into the reducer to ensure that the lubricating oil is added to the appropriate amount. As the work progresses, the working state of the lubricating oil changes, and the operator needs to open the reducer to observe the working state of the lubricating oil, which is a relatively troublesome operation. Secondly, when the vertical reducer is in operation, in order to change the working lubricating oil, the lubricating oil needs to be drained from the reducer. During the process of draining the lubricating oil, certain impurities and grinding debris in the lubricating oil will be deposited at the bottom. When draining the lubricating oil, the grinding debris will remain in the reducer, which will accelerate the wear in subsequent operations. Utility Model Content

[0003] The purpose of this utility model is to provide a vertical reducer with a bearing lubrication system. By setting up a reducer housing, bearing housing, transparent oil tank, internal gear ring and bottom sealing plate, it solves the problems of the cumbersome operation of determining the working state of the lubricating oil in the vertical reducer and the inability to remove grinding debris when changing the lubricating oil.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a vertical speed reducer with a bearing lubrication system, comprising a speed reducer housing, a bearing housing, a transparent oil tank, an internal gear ring, and a bottom sealing plate. Fixed shafts are fixed in a circular array on the inner top of the speed reducer housing. A transmission gear is rotatably connected to the bottom end of each fixed shaft. The outer sides of all the transmission gears are meshed with an internal gear ring. A fixed frame is fixed to the bottom end of the internal gear ring. An output shaft is fixed to the center of the bottom of the fixed frame. A bottom sealing plate is fixed to the bottom end of the speed reducer housing. The output shaft vertically passes through the bottom sealing plate. A limiting plate is fixed to the periphery of the output shaft at the top of the bottom sealing plate. The reducer housing has a ring array of fixed sweeping bars on its sides. The top of the reducer housing is fixedly connected to a bearing housing. A transparent oil tank is provided around the bearing housing. The top of the transparent oil tank is threadedly connected to a sealing cap. Inside the reducer housing, transmission gears are installed through a ring array of fixed shafts. All transmission gears mesh with an internal gear ring. The bottom of the internal gear ring is connected to the output shaft through a fixed frame to realize power output. The bottom of the housing is closed by a bottom sealing plate. The output shaft passes through the bottom sealing plate and is equipped with a limiting plate with sweeping bars for sealing and cleaning debris. The top bearing housing is connected to the housing, and a transparent oil tank is provided on its side. The top is sealed with a sealing cap to facilitate observation of the lubricating oil status.

[0005] Furthermore, a protective sleeve is fixed on the inner wall of the reducer housing, and the internal gear ring is movably connected to the inner side of the protective sleeve. The protective sleeve is fixed to the inner wall of the reducer housing, and the internal gear ring rotates inside the protective sleeve, which serves to limit movement and reduce friction.

[0006] Furthermore, the top of the bearing housing vertically passes through the drive shaft. An inner bearing is interference-fitted around the drive shaft inside the bearing housing. The inner bearing is fixed to the inner wall of the bearing housing. The drive shaft passes through the top of the reducer housing and extends into the top of the reducer housing. A drive gear is fixed at the bottom of the drive shaft. The bottom of the drive gear meshes with all the transmission gears. The drive shaft passes through the bearing housing, is fixed by the inner bearing, and has a drive gear at its bottom. The drive gear meshes with all the transmission gears to transmit the input power to the transmission system.

[0007] Furthermore, a connecting pipe is fixedly connected to the lower periphery of the transparent oil tank, and the connecting pipe is fixedly connected to the lower periphery of the bearing housing. The height of the connecting pipe is lower than the bottom height of the inner bearing. An air filter element is fixedly connected through the center of the top of the sealing cover. The transparent oil tank is connected to the lower part of the bearing housing via the connecting pipe. The position of the connecting pipe is lower than the bottom of the inner bearing. An air filter element is provided on the top of the sealing cover for ventilation and dust prevention. When adding oil, the lubricating oil flows into the bearing housing through the transparent oil tank.

[0008] Furthermore, the bottom end of the limiting plate abuts against the bottom sealing plate, and the end of the sweeping bar away from the limiting plate contacts the inner wall of the reducer housing. The abutment between the limiting plate and the bottom sealing plate enhances the seal, and the sweeping bar contacts the inner wall of the housing, cleaning up deposited debris when rotating to prevent blockage.

[0009] Furthermore, an output pipe is vertically fixed inside the bottom sealing plate on the outside of the limiting plate and the inside of the reducer housing. The top of the output pipe is flush with the top of the limiting plate, and the bottom of the output pipe is threaded with a nut. The output pipe is installed on the bottom sealing plate, with the top of the pipe flush with the top surface of the limiting plate and the bottom of the pipe sealed with a nut. When draining oil, the nut is opened, and the lubricating oil and debris are discharged together.

[0010] This utility model has the following beneficial effects: This invention solves the problem of cumbersome operation in determining the working state of lubricating oil in vertical reducers by setting up a reducer housing, bearing housing, and transparent oil tank. During operation, the state of lubricating oil in the reducer housing can be determined by observing the state of the lubricating oil in the transparent oil tank. When changing the lubricating oil, after emptying the oil from the reducer housing and bearing housing, the sealing cap can be rotated to unscrew the sealing cap from the transparent oil tank. After unscrewing the sealing cap from the transparent oil tank, the oil is poured into the transparent oil tank and transported to the bearing housing through the connecting pipe. This makes it more convenient to determine the working state of the lubricating oil in the vertical reducer and to add lubricating fluid.

[0011] This invention solves the problem of grinding debris not being discharged when changing lubricating oil in vertical reducers by setting up a reducer housing, bearing chamber, internal gear ring, and bottom seal plate. When the used lubricating oil is discharged, the drive shaft continues to rotate, causing the sweeping bar to rotate and tumble the debris and impurities in the lubricating oil in the lower part of the reducer housing. Opening the nut allows the lubricating oil in the reducer housing to be output, reducing the debris and impurities remaining in the reducer housing during operation. This allows grinding debris to be discharged when changing the lubricating oil in the vertical reducer, and makes subsequent lubricating oil additions cleaner. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0016] Please see Figure 1-4This utility model relates to a vertical speed reducer with a bearing lubrication system, comprising a speed reducer housing 1, a bearing housing 2, a transparent oil tank 3, an internal gear ring 4, and a bottom sealing plate 5. Fixed shafts 101 are fixed in a circular array on the inner top of the speed reducer housing 1, connecting structures that alter the torque and speed of the power output end. Transmission gears 102 are connected to the speed reducer housing 1 via the fixed shafts 101. Each fixed shaft 101 has a rotatable transmission gear 102 at its bottom end. The outer sides of all transmission gears 102 are meshed with the internal gear ring 4. The transmission gears 102 transmit power from the drive gear 203 to the internal gear ring 4, causing it to rotate. A fixed frame 401 is fixed to the bottom end of the internal gear ring 4, connecting it to an output shaft 402. The output shaft 402 is fixed to the center of the bottom of the fixed frame 401, outputting the reduced power to external working equipment. A bottom sealing plate 5 is fixed to the bottom end of the housing 1. The output shaft 402 passes vertically through the bottom sealing plate 5, which closes the bottom end of the housing 1. A limit plate 403 is fixed to the periphery of the output shaft 402 at the top of the bottom sealing plate 5. The limit plate 403 closes the gap between the output shaft 402 and the bottom sealing plate 5. A sweeping bar 404 is fixed in a ring array around the periphery of the limit plate 403. When the limit plate 403 rotates, it drives the sweeping bar 404 to sweep inside the lower part of the housing 1, preventing the deposition of grinding debris and ensuring that the debris generated during the deceleration process is directly discharged during oil discharge. A bearing chamber 2 is fixedly connected to the top of the housing 1. The bearing chamber 2 fixes the inner bearing 201 in it. A transparent oil tank 3 is provided around the periphery of the bearing chamber 2. The quality of the oil in the housing 1 can be observed and determined through the transparent oil tank 3. A sealing cover 301 is threadedly connected to the top of the transparent oil tank 3, which closes the top of the transparent oil tank 3.

[0017] Specifically, a sleeve 103 is fixed on the inner wall of the reducer housing 1, and the internal gear ring 4 is movably connected to the inner side of the sleeve 103. The reducer housing 1 limits the internal gear ring 4 in the reducer housing 1 through the sleeve 103, thereby reducing the friction between the internal gear ring 4 and the reducer housing 1.

[0018] Furthermore, the top of the bearing housing 2 vertically passes through the drive shaft 202. An inner bearing 201 is interference-fitted around the drive shaft 202 inside the bearing housing 2. The inner bearing 201 is fixed to the inner wall of the bearing housing 2. The drive shaft 202 passes through the top of the reducer housing 1 and extends into the top of the reducer housing 1. A drive gear 203 is fixed at the bottom of the drive shaft 202. The bottom of the drive gear 203 meshes with all the transmission gears 102. The inner bearing 201 in the bearing housing 2 restricts the position of the drive shaft 202. The top of the drive shaft 202 is fixed to the external motor output end. The drive gear 203 at the bottom of the drive shaft 202 meshes with the transmission gears 102, transmitting power to the transmission gears 102.

[0019] Furthermore, a connecting pipe 303 is fixedly connected to the lower periphery of the transparent oil tank 3. The connecting pipe 303 is fixedly connected to the lower periphery of the bearing housing 2. The height of the connecting pipe 303 is lower than the bottom height of the inner bearing 201. An air filter element 302 is fixedly connected through the center of the top of the sealing cover 301. During normal operation of the internal mechanism of the reducer housing 1, the transparent oil tank 3 displays and determines the liquid level in the bearing housing 2. While allowing air to pass through the air filter element 302, it also prevents dust from entering. When changing the lubricating oil, the sealing cover 301 is unscrewed, and the lubricating oil can be poured into the transparent oil tank 3. The transparent oil tank 3 then transports the oil to the bearing housing 2 through the connecting pipe 303.

[0020] The operation process of this embodiment is as follows: During normal operation, the state of the lubricating oil in the reducer housing 1 can be determined by observing the state of the lubricating oil in the transparent oil tank 3. When changing the lubricating oil, after the oil in the reducer housing 1 and bearing housing 2 has been poured out, the sealing cover 301 can be rotated and unscrewed from the transparent oil tank 3. After the sealing cover 301 is unscrewed from the transparent oil tank 3, the oil is poured into the transparent oil tank 3 and transported to the bearing housing 2 through the connecting pipe 303. Then, it is transported to the reducer housing 1 through the bearing housing 2 until the level of the lubricating oil in the bearing housing 2 rises above the inner bearing 201. During the rotation of the drive shaft 202, the inner bearing 201 is lubricated by the lubricating oil. Specific Implementation Example 2

[0021] Please see Figure 1-7 Based on the first specific embodiment, the bottom end of the limiting plate 403 abuts against the bottom sealing plate 5, and the end of the sweeping bar 404 away from the limiting plate 403 contacts the inner wall of the reducer housing 1. By abutting against the bottom sealing plate 5, the limiting plate 403 increases the sealing of the gap between the output shaft 402 and the bottom sealing plate 5, and by contacting the reducer housing 1 with the sweeping bar 404, it fully cleans the debris deposited on the top of the bottom sealing plate 5.

[0022] Specifically, an output pipe 501 is vertically fixed inside the bottom sealing plate 5 on the outside of the limit plate 403 and the inside of the reducer housing 1. The top of the output pipe 501 is flush with the top of the limit plate 403, and the bottom of the output pipe 501 is threaded with a nut 502. The limit plate 403 discharges the lubricating oil that has been used in the reducer housing 1 for a certain period of time through the output pipe 501, and seals the bottom of the output pipe 501 with the nut 502.

[0023] The operation process of this embodiment is as follows: During operation, the power transmitted by the motor from the drive shaft 202 drives the drive gear 203 to rotate. When the drive gear 203 rotates, it drives the transmission gear 102 and the internal gear ring 4 to rotate. During deceleration, the drive fixing frame 401 drives the output shaft 402 to rotate. The bottom end of the output shaft 402 is connected to the equipment that needs power, driving the working equipment to work. During the rotation of the output shaft 402, the limit plate 403 rotates accordingly. The bottom end of the limit plate 403 abuts against the bottom sealing plate 5, sealing the gap between the output shaft 402 and the bottom sealing plate 5. When the lubricating oil is discharged, the drive shaft 202 continues to rotate, so that the sweeping bar 404 continues to rotate and flips the debris and impurities in the lubricating oil in the lower part of the reducer housing 1. The nut 502 is opened to allow the lubricating oil in the reducer housing 1 to be output, reducing the debris and impurities remaining in the reducer housing 1 during operation.
