Description

Technical Field

[0001] This invention relates to the field of grinding equipment technology, and more specifically, to a grinding equipment for processing lubricated bearing housings. Background Technology

[0002] A bearing housing is a base that provides stable support for a bearing. The bearing housing fixes the bearing in the correct position, ensuring minimal oscillation and displacement when the machine rotates at high speed, thus guaranteeing mechanical precision and stability. To prevent relative rotation between the bearing housing and the bearing, a keyway is provided on the inner wall of the bearing housing, and a pin is provided on the outer wall of the bearing. The engagement of the pin and the keyway restricts relative rotation between the bearing and the bearing housing in the circumferential direction. This engagement method ensures that the bearing and the bearing housing are relatively fixed in the circumferential direction, enabling them to work together to support and transmit the movement and power of the shaft.

[0003] Existing bearing housing grinding equipment uses grinding rollers to grind the inner wall of the bearing housing. However, the grinding rollers cannot make sufficient contact with the inside of the keyway during grinding, resulting in a rough keyway interior. During the use of the bearing housing, the keyway and the pin on the bearing wear continuously, causing poor engagement between the keyway and the pin, which makes the bearing prone to vibration during use. Therefore, this equipment does not meet the current requirements. To address this issue, we propose a grinding equipment for lubricating bearing housing processing. Summary of the Invention

[0004] This invention provides a grinding device for processing lubricated bearing housings. This grinding device can automatically grind the keyway of the bearing housing. After grinding, the inside of the bearing housing is smooth, the pin is not easily worn, and the normal engagement of the keyway and the pin is guaranteed. The bearing is less prone to vibration during use. This solves the problem mentioned in the background art that existing bearing housing grinding devices use grinding rollers to grind the inner wall of the bearing housing. When the grinding rollers grind the inner wall of the bearing housing, they cannot make sufficient contact with the inside of the keyway, resulting in a relatively rough inside of the keyway after grinding. During the use of the bearing housing, the keyway and the pin on the bearing wear continuously, resulting in poor engagement of the keyway and the pin, and the bearing is prone to vibration during use.

[0005] To achieve the above objectives, this disclosure provides a grinding device for processing lubricated bearing housings, including a grinding machine housing, an inner wall roller disposed on the grinding machine housing, a grinding motor disposed inside the grinding machine housing, a turntable motor disposed inside the grinding machine housing, a revolution turntable disposed on the output shaft of the turntable motor, a displacement turntable rotatably mounted on the revolution turntable, the inner wall roller rotatably mounted on the displacement turntable, and a keyway roller disposed on the displacement turntable, the keyway roller being drivenly connected to the grinding motor; When the keyway roller approaches the keyway of the bearing seat, the displacement turntable shifts position, and the keyway roller automatically moves into the keyway.

[0006] Optionally, a keyway roller shaft and an inner wall roller shaft are rotatably mounted on the displacement turntable. One end of the keyway roller shaft is connected to the keyway roller, and a first gear is mounted on the other end of the keyway roller shaft. One end of the inner wall roller shaft is connected to the inner wall roller, and a second gear is mounted on the other end of the inner wall roller shaft. The second gear meshes with the first gear, and a drive gear for meshing with the second gear is mounted on the output shaft of the grinding motor.

[0007] Optionally, the inside of the grinding machine housing is provided with an annular rack, which is configured as a segmented rack. A second rotating shaft is provided on the rotating disk. A displacement gear for intermittently meshing with the annular rack is rotatably mounted on the second rotating shaft. An energy-storing torsion spring is provided on the second rotating shaft. One end of the energy-storing torsion spring is connected to the second rotating shaft, and the other end of the energy-storing torsion spring is connected to the displacement gear. The displacement gear is driven by the displacement rotating disk.

[0008] Optionally, the displacement turntable is provided with a gear ring, and a first rotating shaft is rotatably mounted on the revolution turntable. The first rotating shaft is provided with a one-way gear for meshing with the gear ring, and a transmission gear for meshing with the displacement gear is also provided on the first rotating shaft. A ratchet is provided on the transmission gear, and a pawl is hinged on the first rotating shaft. The ratchet and the pawl are movably engaged.

[0009] Optionally, the second gear is rotatably mounted on the shift turntable, the inner wall roller shaft is slidably inserted into the second gear, and the inner wall roller shaft is provided with a key block for engaging with the second gear; A sleeve is provided on the displacement turntable, and a piston rod is slidably installed in the sleeve. A connecting rod is connected between the piston rod and the inner wall roller shaft. A reset spring is provided in the sleeve, and the other end of the reset spring abuts against the piston rod.

[0010] Optionally, the connecting rod is provided with an abutting block, which is a spherical block. A vertical plate is provided inside the grinding machine housing. A positioning rod is slidably inserted into the vertical plate. A push plate is installed at the end of the positioning rod away from the vertical plate. An energy storage spring is sleeved on the positioning rod. The other end of the energy storage spring is connected to the vertical plate. The push plate intermittently abuts against the abutting block. The revolution turntable is provided with a wedge-shaped block, which slides in contact with the push plate.

[0011] Optionally, an inner wall nozzle and a keyway nozzle are provided on the side of the revolution turntable near the bearing housing, and a water pump is provided on the side of the revolution turntable away from the bearing housing. The inner wall nozzle is configured to be normally started, and the keyway nozzle is configured to be intermittently started.

[0012] Optionally, a piston cylinder is provided on the revolution turntable, and a water inlet pipe is connected between the water inlet of the piston cylinder and the water pump. A first hose is connected between the piston cylinder and the inner wall nozzle, and the first hose is connected to the water inlet pipe. A second hose is connected between the piston cylinder and the keyway nozzle, and the second hose is intermittently connected to the water inlet pipe.

[0013] Optionally, a piston plate is slidably installed in the piston cylinder, and a pull rod is installed on the side of the piston plate away from the first hose. When the pull rod moves away from the water inlet pipe, the second hose is connected to the water inlet pipe. A tension spring is sleeved on the pull rod, and the other end of the tension spring is connected to the piston cylinder. When the pull rod is reset under the tension of the tension spring, the second hose is not connected to the water inlet pipe.

[0014] Optionally, a rotating plate is hinged to the end of the pull rod away from the piston plate, and a return torsion spring is provided on the rotating plate. One end of the return torsion spring is connected to the rotating plate, and the other end of the return torsion spring is connected to the pull rod. The grinding machine housing is provided with a sliding groove, in which a slider is slidably installed. A resistance spring is provided in the sliding groove, with the other end of the resistance spring abutting against the slider. The slider abuts against the rotating plate intermittently.

[0015] Through the above technical solution, the grinding equipment for processing lubricated bearing housings provided in this disclosure operates as follows: for each revolution of the rotating disc, the shifting gear meshes with the ring rack twice, and the energy storage torsion spring stores and releases energy twice. When the energy storage torsion spring is released for the first time, the shifting disc rotates rapidly, and the keyway roller moves to the keyway for grinding. When the energy storage torsion spring is released for the second time, the shifting disc drives the keyway roller to move out of the keyway, thereby realizing automatic grinding of the bearing housing keyway. Moreover, the inner wall of the bearing housing and the keyway are ground synchronously, without the need for additional processes to grind the keyway, thus improving processing efficiency. After grinding, the inside of the bearing housing is smooth, making the pin less prone to wear, ensuring normal engagement of the keyway and the pin, and the bearing is less prone to vibration during use, thus improving the reliability of this device. In addition, after the wedge block separates from the push plate, the push plate pushes the abutment block and connecting rod under the compression of the energy storage spring. At the same time, the inner wall roller shaft and the inner wall roller actively move away from the keyway. This avoids contact between the inner wall roller and the edge of the keyway, prevents the inner wall roller from causing chamfering on the edge of the keyway during grinding, facilitates the normal engagement of the keyway and the pin, and further improves the reliability of the device.

[0016] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

[0030] To make the above-described objects, features, and advantages of this disclosure more apparent and understandable, specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this disclosure. However, this disclosure can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this disclosure. Therefore, this disclosure is not limited to the specific embodiments disclosed below.

[0031] In the description of this disclosure, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this disclosure. The terms "first" and "second" are used to distinguish one element from another and do not have sequential or importance. Furthermore, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings denote the same or similar elements, which will not be repeated here.

[0032] In this disclosure, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0033] According to some embodiments of this disclosure, a grinding apparatus for machining lubricated bearing housings is provided, with reference to... Figures 1 to 13 As shown, the grinding equipment for processing the lubricated bearing housing includes a grinding machine housing 101, an inner wall roller 102 is provided on the grinding machine housing 101, a grinding motor 103 is provided inside the grinding machine housing 101, a turntable motor 221 is provided inside the grinding machine housing 101, a revolution turntable 201 is provided on the output shaft of the turntable motor 221, a displacement turntable 202 is rotatably mounted on the revolution turntable 201, the inner wall roller 102 is rotatably mounted on the displacement turntable 202, and a keyway roller 203 is also provided on the displacement turntable 202. The keyway roller 203 is connected to the grinding motor 103 for transmission. When the keyway roller 203 approaches the keyway of the bearing housing, the keyway roller 203 automatically moves into the keyway.

[0034] Thus, while the inner wall roller 102 grinds the inner wall of the bearing housing, a keyway roller 203 is also provided on the displacement turntable 202. When the keyway roller 203 approaches the keyway of the bearing housing, the displacement turntable 202 rotates and shifts, and the keyway roller 203 automatically moves to the keyway for grinding. This achieves synchronous grinding of the bearing inner wall and the keyway. Because the keyway is ground relatively smoothly, after the bearing is installed in the bearing housing, the friction between the pin on the outer wall of the bearing and the keyway is effectively reduced, thereby reducing the wear of the pin, ensuring the normal engagement of the pin and the keyway, and improving the stability of the bearing during use.

[0035] It should be noted that the rotation axis of the inner wall roller 102 coincides with that of the displacement turntable 202. Therefore, before and after the displacement turntable 202 is displaced, the inner wall roller 102 is always in contact with the inner wall of the bearing housing. Additionally, to ensure the keyway roller 203 moves smoothly into and out of the keyway, please refer to... Figure 1 The rotation direction of the displacement turntable 202 is opposite to that of the revolution turntable 201.

[0036] Additionally, please refer to Figure 2 , Figure 3A keyway roller shaft 204 and an inner wall roller shaft 205 are rotatably mounted on the shifting turntable 202. One end of the keyway roller shaft 204 is connected to the keyway roller 203, and a first gear 206 is mounted on the other end of the keyway roller shaft 204. One end of the inner wall roller shaft 205 is connected to the inner wall roller 102, and a second gear 207 is mounted on the other end of the inner wall roller shaft 205. The second gear 207 meshes with the first gear 206. A drive gear 208 for meshing with the second gear 207 is mounted on the output shaft of the grinding motor 103.

[0037] Further, please refer to Figure 4 , Figure 5 To achieve automatic repositioning of the repositioning turntable 202, an annular rack 215 is provided inside the grinding machine housing 101. The annular rack 215 is a segmented rack. A second rotating shaft 229 is provided on the revolving turntable 201. A repositioning gear 216 for intermittently meshing with the annular rack 215 is rotatably mounted on the second rotating shaft 229. An energy storage torsion spring 230 is provided on the second rotating shaft 229. One end of the energy storage torsion spring 230 is connected to the second rotating shaft 229, and the other end of the energy storage torsion spring 230 is connected to the repositioning gear 216. The repositioning gear 216 is connected to the repositioning turntable 202 for transmission. The segmented positions of the annular rack 215 correspond to the keyway of the bearing seat, ensuring that the repositioning gear 216 only meshes when the keyway roller 203 approaches the keyway.

[0038] It should be noted that for each revolution of the rotating disk 201, the displacement gear 216 meshes with the ring rack 215 twice. When the displacement gear 216 and ring rack 215 mesh for the first time, the displacement gear 216 rotates, and the energy-storing torsion spring 230 is twisted and stores energy by the displacement gear 216. When the displacement gear 216 and ring rack 215 are not meshed, the energy-storing torsion spring 230 is quickly released, causing the displacement gear 216 to rotate in the opposite direction. At this time, the displacement disk 202... The keyway roller 203 rotates rapidly and moves into the keyway for grinding. Then, the displacement gear 216 meshes with the ring rack 215 for the second time, and the energy storage torsion spring 230 is twisted again by the displacement gear 216. After the energy storage keyway roller 203 finishes grinding the keyway, the displacement gear 216 and the ring rack 215 lose mesh, and the energy storage torsion spring 230 is released quickly. The energy storage torsion spring 230 drives the displacement gear 216 to rotate in the opposite direction. At this time, the displacement turntable 202 drives the keyway roller 203 to move out of the keyway.

[0039] For details, please refer to Figure 4 , Figure 6 , Figure 7A gear ring 209 is provided on the displacement turntable 202, and a first rotating shaft 225 is rotatably mounted on the revolution turntable 201. A one-way gear 223 for meshing with the gear ring 209 is provided on the first rotating shaft 225. A transmission gear 217 for meshing with the displacement gear 216 is also provided on the first rotating shaft 225. A ratchet 224 is provided on the transmission gear 217. A pawl 226 is hinged on the first rotating shaft 225. The ratchet 224 and the pawl 226 are movably engaged.

[0040] It should be noted that when the displacement gear 216 meshes with the ring rack 215, the displacement gear 216 drives the transmission gear 217 to rotate. At this time, the ratchet 224 and the pawl 226 are not engaged, so the first rotating shaft 225 does not rotate. When the displacement gear 216 and the ring rack 215 are not engaged, the energy storage torsion spring 230 drives the displacement gear 216 to rotate in the opposite direction. The displacement gear 216 drives the transmission gear 217 to rotate in the opposite direction. At this time, the ratchet 224 and the pawl 226 are engaged, and the transmission gear 217 drives the first rotating shaft 225 to rotate. At the same time, the one-way gear 223 set on the first rotating shaft 225 rotates. The one-way gear 223 drives the displacement turntable 202 to be displaced through meshing with the gear ring 209.

[0041] Additionally, because the inner wall roller 102 performs indiscriminate grinding on the inner wall of the bearing housing, it will cause rounded corners on the keyway edges, affecting the engagement of the keyway and the bearing pin. To avoid the influence of the inner wall roller 102 on the keyway, please refer to... Figure 8 The second gear 207 is rotatably mounted on the shifting turntable 202. The inner wall roller shaft 205 is slidably inserted into the second gear 207. The inner wall roller shaft 205 is provided with a key block 210 for engaging with the second gear 207. The shifting turntable 202 is provided with a sleeve 214. A piston rod 213 is slidably mounted in the sleeve 214. A connecting rod 211 connects the piston rod 213 and the inner wall roller shaft 205. A return spring 228 is provided in the sleeve 214. The other end of the return spring 228 abuts against the piston rod 213. When the inner wall roller 102 approaches the keyway, the inner wall roller shaft 205 and the inner wall roller 102 actively move away from the keyway (see...). Figure 9 When the inner wall roller 102 passes over the keyway, under the action of the reset spring 228 in the sleeve 214, the piston rod 213, the connecting rod 211, the inner wall roller shaft 205 and the inner wall roller 102 are reset.

[0042] Additionally, to enable the inner wall roller 102 to actively move away from the keyway, please refer to... Figure 9 , Figure 10A contact block 212 is provided on the connecting rod 211. The contact block 212 is a spherical block. A vertical plate 218 is provided inside the grinding machine housing 101. A positioning rod 219 is slidably inserted on the vertical plate 218. A push plate 222 is installed on the end of the positioning rod 219 away from the vertical plate 218. An energy storage spring 227 is sleeved on the positioning rod 219. The other end of the energy storage spring 227 is connected to the vertical plate 218. The push plate 222 and the contact block 212 intermittently abut against each other. A wedge block 220 is provided on the revolution turntable 201. The wedge block 220 slides in contact with the push plate 222.

[0043] It should be noted that when the wedge block 220 contacts the push plate 222, the push plate 222 moves away from the contact block 212. At the same time, the energy storage spring 227 is compressed and stored under the pressure of the push plate 222. When the wedge block 220 separates from the push plate 222, the energy storage spring 227 is released. Under the pressure of the energy storage spring 227, the push plate 222 pushes the contact block 212 and the connecting rod 211. At the same time, the inner wall roller shaft 205 and the inner wall roller 102 actively move away from the keyway. When the inner wall roller 102 passes the keyway, the push plate 222 disengages from the contact block 212. Under the action of the reset spring 228 in the sleeve 214, the piston rod 213, the connecting rod 211, the inner wall roller shaft 205 and the inner wall roller 102 are reset.

[0044] Through the above technical solution, the grinding equipment for processing lubricated bearing seats provided in this disclosure, when in use, for each revolution of the rotating disk 201, the displacement gear 216 meshes with the ring rack 215 twice. When the displacement gear 216 meshes with the ring rack 215 for the first time, the displacement gear 216 rotates, and the energy storage torsion spring 230 is twisted and stores energy by the displacement gear 216. When the displacement gear 216 and the ring rack 215 are not meshed, the energy storage torsion spring 230 is quickly released, and the energy storage torsion spring 230 drives the displacement gear 216 to rotate in the opposite direction. At this time, the displacement disk 202 rotates quickly, and the keyway roller 203 moves to the keyway for grinding, and then the displacement... After the gear 216 and the ring rack 215 mesh for the second time, the energy storage torsion spring 230 is twisted again by the shift gear 216. After the energy storage keyway roller 203 finishes grinding the keyway, the shift gear 216 and the ring rack 215 lose meshing, and the energy storage torsion spring 230 is released quickly. The energy storage torsion spring 230 drives the shift gear 216 to rotate in the opposite direction. At this time, the shift turntable 202 drives the keyway roller 203 to move out of the keyway, thereby realizing automatic grinding of the bearing seat keyway. After grinding, the inside of the bearing seat is smooth, making the pin less prone to wear, ensuring the normal engagement of the keyway and the pin, and the bearing is less prone to vibration during use, thus improving the reliability of this device. In addition, when the wedge block 220 on the revolving turntable 201 contacts the push plate 222, the push plate 222 moves away from the contact block 212. At the same time, the energy storage spring 227 is compressed and stored under the pressure of the push plate 222. When the wedge block 220 separates from the push plate 222, the energy storage spring 227 is released. The push plate 222 pushes the contact block 212 and the connecting rod 211 under the pressure of the energy storage spring 227. At the same time, the inner wall roller shaft 205 and the inner wall roller 102 actively move away from the keyway. Therefore, the contact between the inner wall roller 102 and the edge of the keyway is avoided, and the chamfering of the edge of the keyway is prevented when the inner wall roller 102 is polished. This is conducive to the normal engagement of the keyway and the pin, and further improves the reliability of the device.

[0045] It should be noted that the pawl 226 can rotate in one direction through the spring, so that the ratchet 224 can only drive the first rotating shaft 225 to rotate in one direction through the pawl 226. The cooperation between the ratchet 224 and the pawl 226 is well known in the art and will not be described in detail here.

[0046] In some embodiments of this disclosure, reference is made to Figures 1 to 13 As shown, an inner wall nozzle 301 and a keyway nozzle 302 are provided on the side of the revolution turntable 201 near the bearing seat, and a water pump 305 is provided on the side of the revolution turntable 201 away from the bearing seat. The inner wall nozzle 301 is set to be normally open, and the keyway nozzle 302 is set to be intermittently open. The water spraying direction of the inner wall nozzle 301 corresponds to the grinding position of the inner wall roller 102. The keyway nozzle 302 is only turned on when it is above the keyway. At this time, the keyway roller 203 is located outside the keyway, thereby preventing the keyway roller 203 from blocking the keyway nozzle 302.

[0047] For details, please refer to Figure 12 A piston cylinder 308 is installed on the rotating turntable 201. A water inlet pipe 312 is connected between the water inlet of the piston cylinder 308 and the water pump 305. A first hose 306 is connected between the piston cylinder 308 and the inner wall nozzle 301. The first hose 306 is connected to the water inlet pipe 312. A second hose 307 is connected between the piston cylinder 308 and the keyway nozzle 302. The second hose 307 is intermittently connected to the water inlet pipe 312.

[0048] Please refer to the following: Figure 12 , Figure 13A piston plate 314 is slidably installed in the piston cylinder 308. A pull rod 310 is installed on the side of the piston plate 314 away from the first hose 306. The connection between the second hose 307 and the water inlet pipe 312 is controlled by the displacement of the piston plate 314. The displacement of the piston plate 314 is adjusted by the stroke of the pull rod 310. When the pull rod 310 moves away from the water inlet pipe 312, the second hose 307 is connected to the water inlet pipe 312. A tension spring 311 is sleeved on the pull rod 310. The other end of the tension spring 311 is connected to the piston cylinder 308. When the pull rod 310 is reset under the tension of the tension spring 311, the second hose 307 is not connected to the water inlet pipe 312.

[0049] Additionally, a rotating plate 309 is hinged to the end of the pull rod 310 away from the piston plate 314. A return torsion spring 315 is provided on the rotating plate 309. One end of the return torsion spring 315 is connected to the rotating plate 309, and the other end of the return torsion spring 315 is connected to the pull rod 310. A slide groove 304 is provided in the grinding machine housing 101. A slider 303 is slidably installed in the slide groove 304. A resistance spring 313 is provided in the slide groove 304. The other end of the resistance spring 313 abuts against the slider 303. The slider 303 abuts against the rotating plate 309 intermittently. The slider 303 moves by being triggered by the rotation of the displacement turntable 202, causing the rotating plate 309 to periodically abut against the pull rod 310.

[0050] It should be noted that as the revolution turntable 201 rotates, when the keyway nozzle 302 moves to its highest position, the nozzle direction of the keyway nozzle 302 corresponds to the keyway. At this time, the slider 303 abuts against the rotating plate 309, and the rotating plate 309, pull rod 310, and piston plate 314 move away from the water inlet pipe 312. The second hose 307 is connected to the water inlet pipe 312, the keyway nozzle 302 is turned on, and the keyway nozzle 302 washes away the metal particles polished off the keyway. After the slider 303 moves to its maximum displacement, the rotating plate 309 deflects. Pull rod 310 and piston plate 314 are reset under the action of tension spring 311, the second hose 307 is no longer connected to the water inlet pipe 312, and the keyway nozzle 302 is closed. At this time, rinsing is completed. The keyway nozzle 302 is opened intermittently, which can clean the keyway in a targeted manner, thereby saving water. At the same time, the keyway nozzle 302 is only opened when it is above the keyway, so that the keyway nozzle 302 can rinse the dead corners of the keyway. Moreover, at this time, the keyway roller 203 is outside the keyway, thereby preventing the keyway roller 203 from blocking the keyway nozzle 302.
