Description

Technical Field

[0001] This invention relates to the field of bearing lubrication technology, specifically to a grease filling device and method for tapered roller bearings. Background Technology

[0002] Tapered roller bearings are a common type of bearing. Their notable feature is that the inner ring, cage, and tapered rollers are integrated into one piece and can be easily separated from the outer ring. Most existing tapered roller bearing grease filling devices involve removing the outer ring and then filling the inner ring as a whole.

[0003] Currently, grease filling devices for tapered roller bearings are mainly divided into two categories. One type places the inner ring structure on a grease-extruding nozzle. After fixing, a pressure device forces the grease from the nozzle into the gaps between the tapered rollers. The other type uses a small filling nozzle to fill the gaps between the tapered rollers one by one. The former type has the advantage of high filling efficiency because all gaps are filled at the same time. However, in this method, more grease overflows, making the work surface very messy, and the exposed grease is easily contaminated, thus aggravating the wear of the tapered rollers. The latter type has the advantages of more complete filling of the gaps with grease, less grease overflow, and a cleaner work surface. Of course, because it is filled one at a time, the filling efficiency is lower. Summary of the Invention

A spring is sleeved on the outer side of each first guide rod between the slider and the base. The dispensing assembly includes a second frame, a tapered tube installed inside the platform of the second frame, a feed tube connected to the bottom end of the tapered tube, a piston ring adapted inside the feed tube, a fourth cylinder connected to the bottom end of the piston ring, a sealing cap for sealing the top end of the tapered tube installed on the top of the platform of the second frame, a ring seat installed in the middle of the top of the sealing cap, and multiple dispensing needles evenly arranged around the top of the ring seat; The feeding assembly includes a circular conveyor line and a feeding mechanism located at one corner of the top of the circular conveyor line. The feeding mechanism includes a gantry frame located at the top of the circular conveyor line. An installation arm is installed on one side of the gantry frame, a first material-pulling plate is installed at the bottom of one side of the installation arm, a second material-pulling plate is installed at the bottom of the other side of the installation arm, a fifth cylinder is installed on the other side of the gantry frame, a baffle is installed at the telescopic end of the fifth cylinder, and an extension arm is installed in the middle of one side of the other side of the gantry frame, with a sensor installed at one end of the extension arm.

[0006] As a preferred embodiment of the present invention, the input end of the cam divider is connected to a motor.

[0007] As a preferred embodiment of the present invention, the picking component further includes a first frame, the top of which is mounted on the bottom of a support column.

[0008] As a preferred embodiment of the present invention, a bottom cover is installed at the bottom of the feeding pipe, and the top of the fourth cylinder is installed at the bottom of the bottom cover.

[0009] As a preferred embodiment of the present invention, a second guide rod is slidably provided on both sides of the inner side of the bottom cover, and the top ends of the second guide rods are respectively installed on the bottom sides of the piston ring.

[0010] As a preferred embodiment of the present invention, the first feeding plate and the second feeding plate are arranged in a trumpet shape and the baffle is close to the small opening of the trumpet.

[0011] As a preferred embodiment of the present invention, the sensor is an infrared sensor.

[0012] A method for adding grease to a tapered roller bearing using a grease-filling device includes the following steps: Step 1: Place the bearings on the circular conveyor line with the outer ring of the bearing at the bottom and the inner ring at the top. When the circular conveyor line is conveying, the first and second guide plates keep the forward path of the bearings consistent. The position of the previous bearing is detected by the sensor, and the timing of the release of the next bearing by the baffle is also used to keep the spacing between adjacent bearings consistent. Step 2: The rotating frame is suspended above the circular conveyor line by the cam divider. When a bearing is conveyed to the bottom of the frame, the circular conveyor line stops conveying. The first cylinder inside the frame is then extended until the annular air bag is inserted into the inner ring of the bearing. Then the second cylinder extends and pushes the sliding sleeve retaining ring down. After squeezing the annular air bag, it expands radially and fits tightly against the inner ring of the bearing. The first cylinder contracts, causing the inner ring of the bearing, along with its integral tapered rollers and cage, to move upward together until it separates from the outer ring and completes the pickup action. At this point, the circular conveyor line starts conveying again. Step 3: Rotate the boom above the filling assembly using the cam divider. Then, the first cylinder extends again to drive the inner ring downwards. When the tapered rollers on the side touch the limiting protrusion, the first cylinder stops extending. Then, the third cylinder pushes and pulls the slider to make the limiting protrusion swing back and forth. At the same time, the first cylinder retracts and extends upwards, causing the inner ring to move up and down. Because the tapered rollers can rotate freely around the center of the inner ring, under the combined effect of the multiple back-and-forth swings of the limiting protrusion and the multiple up-and-down movements of the inner ring, a certain tapered roller will easily embed between the limiting protrusions. The limiting protrusions keep the tapered rollers in the same position, thus ensuring that the gap between adjacent tapered rollers of each subsequent bearing pickup corresponds to the filling needle below. Step 4: The first cylinder extends again until the injection needle enters the gap between adjacent tapered rollers. Then the fourth cylinder extends a certain length, and the grease stored in the tapered tube and the feed tube can be quantitatively discharged through the injection needle via the piston ring, that is, injected into the gap between adjacent tapered rollers. Step 5: Rotate the boom to the other side of the circular conveyor line using the cam divider. At this time, the outer ring that is stuck on the circular conveyor line is exactly below the boom. Extend the first cylinder and then retract the second cylinder to re-engage the inner and outer rings until all grease filling is completed. Step 6: Repeat steps 1 to 5 to achieve uninterrupted grease filling.

[0013] This invention, through the combined action of the repeated back-and-forth swinging of the limiting protrusions and the repeated up-and-down movement of the inner ring, ensures that a certain tapered roller of the bearing will easily embed between the limiting protrusions. The limiting protrusions keep the tapered rollers in the same position, thereby ensuring that the gap position between adjacent tapered rollers of each subsequent bearing picked up corresponds to the filling needle below, ensuring that the docking before subsequent filling can be carried out stably.

[0014] In this invention, after the injection needle is inserted into the gap between adjacent tapered rollers, the fourth cylinder extends a certain length, and the grease stored in the tapered tube and the feed tube can be quantitatively discharged through the injection needle via the piston ring. In other words, it is quantitatively injected into the gap between adjacent tapered rollers, which not only avoids a large amount of grease overflow and keeps the work surface clean, but also completes the entire injection work in one go while keeping the grease filling the entire gap.

[0015] In this invention, during the conveying of the circular conveyor line, the forward path of the bearings is kept consistent by the deflection of the first and second deflector plates. After the previous bearing is sensed by the sensor, the timing for controlling the release of the next bearing after sensing can be calculated by calculating the time after sensing, thereby maintaining the consistent interval between adjacent bearings to facilitate subsequent picking operations.

[0016] In this invention, by replacing different sealing caps and matching injection needles on the ring seat, it can be adapted to use bearings of other specifications, thus expanding its application potential. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figure 1-2 As shown, this embodiment of the invention provides a grease-filling device for tapered roller bearings, including a pickup assembly 1, a correction assembly 2, a filling assembly 3, and a feeding assembly 4. The pickup assembly 1, the correction assembly 2, and the filling assembly 3 are all located at one end inside the annular feeding assembly 4. The filling assembly 3 is located on one side of the pickup assembly 1, and the correction assembly 2 is located in the middle of the pickup assembly 1 and above the filling assembly 3. The pickup assembly 1 can rotate intermittently to pick up the inner ring of the tapered roller bearing, along with its integral tapered rollers and cage, from one side of the feeding assembly 4, and detach it from the outer ring. The position of the tapered rollers is corrected sequentially by the correction assembly 2. After grease is added by the filling assembly 3, the device is released to the other side of the feeding assembly 4 and reassembled with the outer ring that has been conveyed there.

[0021] In this embodiment, reference Figure 3-6 The pickup assembly 1 includes a support column 102. A cam divider 103 is mounted on the top of the support column 102 for intermittent rotation. A rotating frame 105 is connected to the top of the output end of the cam divider 103. A first cylinder 106 is installed inside the distal end of each arm of the rotating frame 105. An assembly column 107 is mounted on the bottom of the first cylinder 106. A sliding retaining ring 108 is sleeved on the outside of the assembly column 107. A bottom retaining ring 109 is mounted on the bottom of the assembly column 107. The outside of the assembly column 107 is located between the sliding retaining ring 108 and the bottom retaining ring 109. A closed annular airbag 110 is provided between 9. The top of the annular airbag 110 is connected to the sliding sleeve retaining ring 108, and the bottom of the annular airbag 110 is connected to the bottom retaining ring 109. In this embodiment, when the closed annular airbag 110 is axially compressed by the sliding sleeve retaining ring 108, it will expand radially, thereby tightly adhering to the inner ring of the bearing and realizing the pickup of the inner ring of the bearing. A second cylinder 111 is installed on the outside of the mounting column 107 above the sliding sleeve retaining ring 108. The telescopic end of the second cylinder 111 is connected to the side of the sliding sleeve retaining ring 108.

[0022] In this embodiment, reference Figure 7-9The correction assembly 2 includes a mounting base 201 installed in the middle of the outside of the support column 102. A side arm 202 is mounted on one side of the mounting base 201. A groove is provided inside one end of the side arm 202, and a slider 203 is slidably mounted inside the groove. A third cylinder 204 is mounted at one end of the groove, and the telescopic end of the third cylinder 204 is connected to one end of the slider 203. A base 205 is provided on one side of the slider 203, and a pair of limiting protrusions 206 are provided on one side of the base 205. The spacing of the limiting protrusions 206 is consistent with the width of the portion of the tapered roller exposed outside the cage. A pair of first guide rods 207 are provided on the other side of the base 205. The guide rod 207 is slidably disposed on both sides of the inside of the slider 203. The outer side of the first guide rod 207 is fitted with a spring between the slider 203 and the base 205. In this embodiment, under the combined action of the repeated back-and-forth swing of the limiting protrusion 206 and the repeated up-and-down movement of the inner ring, a certain tapered roller of the bearing will easily embed between the limiting protrusions 206. The limiting protrusions 206 keep the position of the tapered rollers consistent, thereby ensuring that the gap position between adjacent tapered rollers of each subsequent bearing picked up corresponds to the filling needle tube 310 below, ensuring that the subsequent docking before filling can be carried out stably.

[0023] In this embodiment, reference Figure 10-11 The filling assembly 3 includes a second frame 301. A tapered tube 302 is installed inside the platform of the second frame 301. A feed pipe 303 is connected to the bottom end of the tapered tube 302. A piston ring 304 is fitted inside the feed pipe 303. A fourth cylinder 306 is connected to the middle of the bottom end of the piston ring 304. A sealing cap 308 is installed on the top of the platform of the second frame 301 to seal the top end of the tapered tube 302. A ring seat 309 is installed in the middle of the top of the sealing cap 308. Multiple ring seats are evenly arranged around the top of the ring seat 309. In this embodiment, after the injection needle 310 is inserted into the gap between adjacent tapered rollers, the fourth cylinder 306 extends a certain length, and the grease stored in the tapered tube 302 and the feed tube 303 can be quantitatively discharged through the injection needle 310 via the piston ring 304. That is, quantitative injection is added into the gap between adjacent tapered rollers, which avoids a large amount of grease overflow, keeps the work surface clean, and can complete the entire injection work in one go while keeping the grease filling the entire gap.

[0024] In this embodiment, reference Figure 12-13The feeding assembly 4 includes a circular conveyor line 401 and a feeding mechanism located at one corner of the top of the circular conveyor line 401. The feeding mechanism includes a gantry frame 402 located at the top of the circular conveyor line 401. An installation arm 403 is installed on one side of the gantry frame 402. A first material-pulling plate 404 is installed at the bottom of one side of the installation arm 403. A second material-pulling plate 405 is installed at the bottom of the other side of the installation arm 403. A fifth cylinder 406 is installed on the other side of the gantry frame 402. A baffle 407 is installed at the telescopic end of the fifth cylinder 406. An extension arm 408 is installed in the middle of one side of the other side of the gantry frame 402. A sensor 409 is installed at one end of the extension arm 408.

[0025] In this embodiment, refer again Figure 3 The input end of the cam divider 103 is connected to a motor 104.

[0026] The pickup assembly 1 also includes a first frame 101, the top of which is mounted on the bottom of the support column 102.

[0027] In this embodiment, refer again Figure 10 The bottom of the feed pipe 303 is fitted with a bottom cover 305, and the top of the fourth cylinder 306 is fitted with the bottom of the bottom cover 305.

[0028] The bottom cover 305 has a second guide rod 307 slidably mounted on both sides of its interior, and the top ends of the second guide rod 307 are respectively installed on the bottom sides of the piston ring 304.

[0029] In this embodiment, refer again Figure 13 The first feeding plate 404 and the second feeding plate 405 are arranged in a funnel shape, and the baffle 407 is close to the small opening of the funnel.

[0030] In this embodiment, sensor 409 is an infrared sensor. It is used to assist in separating adjacent bearings. After the preceding bearing is sensed by sensor 409, since the distance between sensor 409 and baffle 407 remains constant, and the conveying speed of the circular conveyor line 401 remains constant, the displacement of the preceding bearing during that time period can be calculated by calculating the time after sensing. Adding this displacement to the distance between sensor 409 and baffle 407 yields the spacing between adjacent bearings. This allows for controlling the appropriate release time of the following bearing after sensing, maintaining consistent spacing between adjacent bearings to facilitate subsequent pickup operations.

[0031] The present invention also provides a method for adding grease to a tapered roller bearing using a grease-adding device, comprising the following steps: Step 1: Place the bearings on the circular conveyor line 401 with the outer ring of the bearing at the bottom and the inner ring at the top. When the circular conveyor line 401 is conveying, the first feed plate 404 and the second feed plate 405 keep the forward path of the bearings consistent. The sensor 409 detects the position of the previous bearing and the timing of releasing the next bearing through the baffle 407 to keep the spacing between adjacent bearings consistent.

[0032] Step 2: The cam divider 103 suspends one arm of the rotating frame 105 above the annular conveyor line 401. When a bearing is conveyed to the bottom of the arm, the annular conveyor line 401 stops conveying and extends the first cylinder 106 inside the arm until the annular air bag 110 is inserted into the inner ring of the bearing. Then, the second cylinder 111 extends and pushes the sliding sleeve retaining ring 108 down. After squeezing the annular air bag 110, it expands radially and fits tightly against the inner ring of the bearing. The first cylinder 106 contracts, causing the inner ring of the bearing, along with its integral tapered rollers and cage, to move upward together until it detaches from the outer ring and completes the pickup action. At this time, the annular conveyor line 401 starts conveying again.

[0033] Step 3: The boom is rotated above the filling assembly 3 by the cam divider 103. Then, the first cylinder 106 extends again to drive the inner ring downward. When the tapered roller on the side touches the limiting protrusion 206, the first cylinder 106 stops extending. Then, the third cylinder 204 pushes and pulls the slider 203 to make the limiting protrusion 206 swing back and forth. At the same time, the first cylinder 106 retracts and extends upward, making the inner ring move up and down. Because the tapered roller can rotate freely around the center of the inner ring, under the combined action of the multiple back and forth swings of the limiting protrusion 206 and the multiple up and down movements of the inner ring, a certain tapered roller will easily embed between the limiting protrusions 206. The limiting protrusions 206 keep the position of the tapered rollers consistent, thereby ensuring that the gap position between adjacent tapered rollers of each subsequent bearing pickup corresponds to the filling needle tube 310 below.

[0034] Step 4: The first cylinder 106 extends again until the injection needle 310 extends into the gap between adjacent tapered rollers. Then the fourth cylinder 306 extends a certain length, and the grease stored in the tapered tube 302 and the feed tube 303 can be quantitatively discharged through the injection needle 310 via the piston ring 304, that is, injected into the gap between adjacent tapered rollers.

[0035] Step 5: Rotate the boom to the other side of the annular conveyor line 401 using the cam divider 103. At this time, the outer ring remaining on the annular conveyor line 401 is just below the boom. Extend the first cylinder 106 and then retract the second cylinder 111 to reconnect the inner and outer rings until all grease filling is completed.

[0036] Step 6: Repeat steps 1 to 5 to achieve uninterrupted grease filling.

[0037] In operation, the bearings are first placed on the annular conveyor line 401 at intervals. During conveying, the annular conveyor line 401 maintains a consistent spacing between adjacent bearings through a fabric distribution mechanism. Then, one arm of the rotating frame 105 is suspended above the annular conveyor line 401 by the cam divider 103. When a bearing is conveyed to the bottom of the arm, the annular conveyor line 401 stops conveying and extends the first cylinder 106 inside the arm until the annular air bladder 110 is inserted into the inner ring of the bearing. Then, the second cylinder 111 extends and pushes the sliding retaining ring 108 down, squeezing the annular air bladder 110 and causing it to expand radially, thus tightly fitting with the inner ring of the bearing. The first cylinder 106 contracts, causing the inner ring of the bearing, along with its integral tapered rollers and cage, to move upward together until it detaches from the outer ring and completes the pickup action. At this point, the annular conveyor line 401 resumes conveying.

[0038] The boom is rotated again above the filling assembly 3 by the cam divider 103, and then the first cylinder 106 extends again to drive the inner ring downward. When the tapered roller on the side touches the limiting protrusion 206, the first cylinder 106 stops extending. Then the third cylinder 204 pushes and pulls the slider 203 to make the limiting protrusion 206 swing back and forth. At the same time, the first cylinder 106 retracts and extends upward, making the inner ring move up and down. Because the tapered roller can rotate freely around the center of the inner ring, under the combined action of the multiple back and forth swings of the limiting protrusion 206 and the multiple up and down movements of the inner ring, a certain tapered roller will easily embed between the limiting protrusions 206. The limiting protrusions 206 keep the position of the tapered rollers consistent, thereby ensuring that the gap position between the adjacent tapered rollers of each subsequent bearing pickup corresponds to the filling needle tube 310 below.

[0039] The first cylinder 106 extends again until the filling needle 310 enters the gap between adjacent tapered rollers. Then the fourth cylinder 306 extends a certain length, and the grease stored in the tapered tube 302 and the feed tube 303 is discharged quantitatively through the filling needle 310 via the piston ring 304, that is, injected into the gap between adjacent tapered rollers. The boom is rotated to the other side of the annular conveyor line 401 by the cam divider 103. At this time, the outer ring that is stuck on the annular conveyor line 401 is exactly below the boom. The first cylinder 106 extends and then the second cylinder 111 retracts to reconnect the inner and outer rings until all grease filling is completed. By repeating the above, uninterrupted grease filling can be achieved.

5. A grease-filling device for a tapered roller bearing according to claim 4, characterized in that: The bottom cover (305) has a second guide rod (307) slidably provided on both sides of its interior. The top ends of the second guide rod (307) are respectively installed on the bottom sides of the piston ring (304).

6. The grease filling device for a tapered roller bearing according to claim 1, characterized in that: The first feeding plate (404) and the second feeding plate (405) are arranged in a trumpet shape, and the baffle (407) is close to the small opening of the trumpet.

7. The grease filling method of the tapered roller bearing grease filling device according to claim 1, characterized in that: Includes the following steps: Step 1: Place the bearings on the circular conveyor line (401) with the outer ring of the bearing at the bottom and the inner ring at the top. When the circular conveyor line (401) is conveying, the first push plate (404) and the second push plate (405) keep the forward path of the bearings consistent. The sensor (409) detects the position of the previous bearing and the timing of releasing the next bearing through the baffle (407) to keep the spacing between adjacent bearings consistent. Step 2: The rotating frame (105) is suspended above the annular conveyor line (401) by the cam divider (103). When a bearing is transported to the bottom of the arm, the annular conveyor line (401) stops its transport action and extends the first cylinder (106) inside the arm until the annular air bag (110) is inserted into the inner ring of the bearing. Then the second cylinder (111) extends and pushes the sliding sleeve retaining ring (108) down. After squeezing the annular air bag (110), it expands radially and fits tightly with the inner ring of the bearing. The first cylinder (106) contracts, causing the inner ring of the bearing, as well as its integral tapered rollers and cage, to move upward together until they are separated from the outer ring and the picking action is completed. At this time, the annular conveyor line (401) starts its transport action again. Step 3: The boom is rotated above the filling assembly (3) by the cam divider (103), and then the first cylinder (106) extends again to drive the inner ring downward. When the conical roller on the side touches the limiting protrusion (206), the first cylinder (106) stops extending. Then the third cylinder (204) pushes and pulls the slider (203) to make the limiting protrusion (206) swing back and forth. At the same time, the first cylinder (106) retracts upward and then extends again, so that the inner ring moves up and down back and forth. Because the tapered rollers can rotate freely around the center of the inner ring, under the combined effect of the repeated back-and-forth swinging of the limiting protrusion (206) and the repeated up-and-down movement of the inner ring, a certain tapered roller will easily embed between the limiting protrusions (206). The limiting protrusions (206) keep the tapered rollers in the same position, thereby ensuring that the gap position between adjacent tapered rollers of each subsequent bearing pick-up corresponds to the filling needle tube (310) below. Step 4: The first cylinder (106) extends again until the injection needle (310) extends into the gap between the adjacent tapered rollers. Then the fourth cylinder (306) extends a certain length, and the grease stored in the tapered tube (302) and the feed tube (303) can be discharged quantitatively through the injection needle (310) via the piston ring (304), that is, injected into the gap between the adjacent tapered rollers. Step 5: Rotate the boom to the other side of the circular conveyor line (401) using the cam divider (103). At this time, the outer ring that is stuck on the circular conveyor line (401) is just below the boom. Extend the first cylinder (106) and then retract the second cylinder (111) to reconnect the inner and outer rings until all grease filling operations are completed. Step 6: Repeat steps 1 to 5 to achieve uninterrupted grease filling.
