Description

Technical Field

[0001] This invention relates to the field of brake technology, and more specifically, to a brake lubrication method and system. Background Technology

[0002] As a critical component in mechanical equipment, the regular lubrication of the gear transmission parts of the brake is essential for ensuring braking performance and extending service life. Currently, common automated lubrication methods often employ a fixed-point grease injection strategy, where an actuator precisely moves the grease injection device onto the gears to apply grease. However, after grease injection, to avoid interference or collision with the gears when removing the grease injection device from the brake, a lifting or retracting reset action is necessary. This waiting period for the grease injection head to reset introduces unnecessary waiting time, reducing the operational efficiency of the lubrication station itself and affecting the cycle time and continuity of the entire production line, making it difficult to meet the demands of modern manufacturing for high efficiency and fast cycle times.

[0003] Therefore, a new brake lubrication method is urgently needed to solve the problem of low production efficiency caused by the need to wait for the grease injection device to reset after the existing brake lubrication is completed before the brake can be moved to the next work station. Summary of the Invention

[0004] To address the low production efficiency caused by the need to wait for the grease injection device to reset after the existing brake lubrication is completed before the brake can be moved to the next workstation, this invention provides a brake lubrication method and apparatus.

[0005] In a first aspect, the present invention provides a brake lubrication method, comprising:

[0006] Based on the brake lubrication command, the grease injection assembly extends to the meshing periphery of the driven gear and the transmission gear of the brake assembly, and toward the outer periphery of the driven gear;

[0007] Obtain the preset rotation rules, and then obtain the preset grease injection volume based on the preset rotation rules;

[0008] The transmission gear drives the driven gear to rotate based on a preset rotation rule;

[0009] The grease injection assembly supplies grease to the outer periphery of the driven gear based on a preset grease injection amount;

[0010] The driven gear transfers grease to the drive gear along its outer circumference, thus completing the lubrication process.

[0011] After lubrication is completed, the delivery assembly moves the braking assembly away from the grease injection assembly.

[0012] In some embodiments, the preset rotation rules include:

[0013] The transmission gear drives the driven gear to rotate circumferentially in a first direction; or, the transmission gear drives the driven gear to rotate circumferentially in a second direction; wherein the second direction is opposite to the first direction.

[0014] In some embodiments, the preset rotation rules further include:

[0015] The speed at which the transmission gear drives the driven gear to rotate circumferentially in the first direction is greater than the speed at which the transmission gear drives the driven gear to rotate circumferentially in the second direction.

[0016] In some embodiments, obtaining the preset grease injection volume based on a preset rotation rule includes:

[0017] When the transmission gear drives the driven gear to rotate circumferentially in the first direction, the grease injection assembly supplies the first amount of grease.

[0018] When the transmission gear drives the driven gear to rotate circumferentially in the second direction, the grease injection assembly supplies a second grease injection amount; wherein, the first grease injection amount is greater than the second grease injection amount.

[0019] In some embodiments, the first grease injection volume accounts for 60%-90% of the total grease injection volume.

[0020] In some embodiments, the braking assembly further includes an integrally formed support base, a first protective cover, and a second protective cover; the driven gear and the transmission gear are disposed on the support base; the first protective cover and the second protective cover surround opposite sides of the transmission gear and extend toward the meshing point of the transmission gear and the driven gear.

[0021] The driven gear transfers grease to the transmission gear along its outer periphery, including: when the transmission gear drives the driven gear to rotate circumferentially in the first direction, a portion of the grease is squeezed out at the meshing point and falls into the first protective cover;

[0022] When the transmission gear drives the driven gear to rotate circumferentially in the second direction, some of the grease falls into the second protective cover.

[0023] In some embodiments, the process of the driven gear transferring grease to the transmission gear along its outer circumference and completing lubrication further includes:

[0024] Based on the grease injection stop command, the grease injection assembly stops supplying grease to the outer circumference of the driven gear;

[0025] Based on the preset rotation rules, the transmission gear continues to drive the driven gear to rotate circumferentially in the first and second directions in sequence;

[0026] Upon receiving a stop command from the braking assembly, the braking assembly completes lubrication.

[0027] In some embodiments, the grease injection assembly has a gap between the radial side of the drive gear and the meshing circumference; the grease is supplied in a spray manner to the outer circumference of the driven gear.

[0028] In a second aspect, the present invention provides a brake lubrication system, comprising:

[0029] support;

[0030] A braking assembly is mounted on a bracket; the braking assembly includes a drive unit and a support unit; the drive unit includes a motor and a drive gear, the drive gear being driven and connected to the motor; the support unit includes a support shell, a support base, and a meshing transmission gear and a driven gear; the support shell and the support base enclose a cavity, the transmission gear and the driven gear are mounted on the support base and located within the cavity; the transmission gear is driven and connected to the drive gear.

[0031] The grease injection assembly is mounted on a bracket. The grease injection assembly includes a grease storage unit, a grease pump, a vertical displacement unit, and a grease supply head. The grease storage unit is fixedly mounted on the bracket. The grease pump is located inside the grease storage unit and connected to the grease supply head. The vertical displacement unit is connected to the grease supply head. The grease supply head extends to the meshing point of the drive gear and the driven gear and faces the outer periphery of the driven gear.

[0032] A conveying assembly is mounted on a support; the conveying assembly includes a conveyor belt and a carrier tray slidably connected to the conveyor belt; a braking assembly is mounted on the carrier tray, and the carrier tray drives the braking assembly to move along the grease injection assembly toward the outer periphery of the driven gear based on the conveyor belt.

[0033] In some embodiments, the support unit further includes:

[0034] The first and second protective covers are positioned on opposite sides of the transmission gear and extend toward the meshing point of the transmission gear and the driven gear.

[0035] To address the low production efficiency caused by the need to wait for the grease injection device to reset after the existing brake lubrication process before moving the brake to the next workstation, this invention has the following advantages:

[0036] 1. By positioning the grease injection assembly directly on the meshing circumference and towards the meshing outer circumference, it ensures that the grease can be introduced into the driven gear or transmission gear from the optimal position, laying the positional foundation for subsequent efficient lubrication.

[0037] 2. The rotation and grease injection amount of the drive gear and driven gear are based on the preset rotation and preset grease injection amount, which facilitates the uniform distribution of grease and reduces grease waste. During the lubrication process, the driven gear transfers grease to the drive gear by means of the centrifugal force of rotation and the squeezing action of the meshing surface, so that the grease can automatically, quickly and evenly cover the working surface of the gear and form a good oil film, which has a better lubrication effect than static coating.

[0038] 3. By moving the braking component away from the grease injection component through the conveying component, the grease injection component is spared the return action and corresponding waiting time, directly shortening the lubrication cycle to the shortest possible time, which greatly improves the lubrication efficiency and the overall efficiency of the production line.

[0047] In industrial automated production lines, regular and efficient lubrication of key transmission components such as brakes is crucial for ensuring the long-term stable operation of equipment. Currently, common automated lubrication methods often employ a fixed-point grease injection strategy, where an actuator precisely moves the grease injection device to the gear meshing point to apply grease. However, this method requires the grease injection device to retract after lubrication and fully reset before the lubricated component can move to the next station, resulting in reduced lubrication efficiency and impacting the overall production line efficiency. Therefore, to address the low production efficiency caused by the need to wait for the grease injection device to reset after brake lubrication before moving the brake to the next station, this invention provides a brake lubrication method and apparatus.

[0048] Example 1

[0049] Please refer to Figure 1The present invention provides a brake lubrication method, comprising steps S10-S60:

[0050] S10, based on the brake lubrication command, the grease injection assembly 30 extends to the meshing periphery of the driven gear 44 and the transmission gear 43 of the brake assembly 40, and toward the outer periphery of the driven gear 44.

[0051] Please refer to Figure 3 and Figure 4 Specifically, the grease injection assembly 30 includes a grease storage unit 31, a grease pump 32, and a grease supply head 34. The grease pump 32 is located within the grease storage unit 31 and connected to the grease supply head 34. The grease storage unit 31 stores grease, and the grease pump 32 supplies the grease to the grease supply head 34, which then supplies the grease to the outer periphery of the driven gear 44. Furthermore, the grease injection assembly 30 also includes a vertical displacement unit 33 connected to the grease supply head 34. Based on this vertical unit, the grease supply head 34 can extend towards one side of the braking assembly 40 and reach the meshing periphery of the transmission gear 43 and the driven gear 44. The grease supply head 34 can face the outer periphery of the driven gear 44, ensuring that the grease can be introduced into the transmission gear 43 and / or the driven gear 44 from the optimal position, laying the positional foundation for subsequent uniform and efficient lubrication.

[0052] Understandably, the grease injection assembly 30 has a gap between the radial side of the drive gear 43 and the meshing circumference. Based on the grease supply head 34 facing the outer circumference of the driven gear 44, grease is supplied to the outer circumference of the driven gear 44 in a spray-like manner. Furthermore, to ensure that the grease supply head 34 can supply to the outer circumference of the driven gear 44, the extension position of the grease supply head 34 towards the drive gear 43 is lower than the upper surface of the drive gear 43. This position allows the brake assembly 40 to move only to the other side, i.e., away from the grease injection assembly 30, after grease injection is completed. This ensures that the grease injection assembly 30 will not damage the brake assembly 40, and that grease can be introduced from the optimal position between the drive gear 43 and / or the driven gear 44, while simultaneously improving the lubrication efficiency of the brake assembly.

[0053] S20, obtain the preset rotation rule, and obtain the preset grease injection amount based on the preset rotation rule.

[0054] Please refer to Figure 5 Specifically, the preset rotation rules include:

[0055] The transmission gear 43 drives the driven gear 44 to rotate circumferentially along the first direction R; or, the transmission gear 43 drives the driven gear 44 to rotate circumferentially along the second direction L; wherein the second direction L is opposite to the first direction R.

[0056] Specifically, the preset rotation rules also include:

[0057] The speed at which the transmission gear 43 drives the driven gear 44 to rotate circumferentially in the first direction R is greater than the speed at which the transmission gear 43 drives the driven gear 44 to rotate circumferentially in the second direction L.

[0058] Specifically, the preset grease injection volume is obtained based on preset rotation rules, including:

[0059] When the transmission gear 43 drives the driven gear 44 to rotate circumferentially in the first direction R, the grease injection assembly 30 supplies a first grease injection amount; when the transmission gear 43 drives the driven gear 44 to rotate circumferentially in the second direction L, the grease injection assembly 30 supplies a second grease injection amount; wherein, the first grease injection amount is greater than the second grease injection amount.

[0060] Specifically, the first injection volume accounts for 60%-90% of the total injection volume, and the first injection volume accounts for 40%-10% of the total injection volume. This ratio is subject to actual application and is not limited in this invention.

[0061] Understandably, the preset rotation rules and preset grease injection amount are related. Based on the position of the grease injection head, the transmission gear 43 drives the driven gear 44 to rotate circumferentially in the first direction R. This rotation direction will cause the grease to be subjected to strong compression when the gears mesh, so that it is quickly and deeply introduced into the meshing surface of the transmission gear 43 to form a good oil film.

[0062] Meanwhile, the rotational speed in the first direction R is greater than that in the second direction L to ensure sufficient and reliable lubrication; therefore, a larger initial grease injection volume is set accordingly. The transmission gear 43 drives the driven gear 44 to rotate circumferentially in the second direction L, achieving uniform coverage and comprehensive lubrication of the gear's working surface and avoiding dead zones. Since the rotational path in the second direction L is relatively long, excessive speed could cause grease to splash under centrifugal force or accumulate in unnecessary areas; therefore, a lower rotational speed is used to allow sufficient time for even application of the grease. Based on this principle, the grease injection volume in the second direction L is also reduced accordingly to precisely meet the needs of auxiliary application, effectively preventing waste and contamination. The entire lubrication process utilizes the dual effects of rotational centrifugal force and meshing compression, and through the coordination of speed and the first and second grease injection volumes, achieves precise on-demand grease distribution, significantly improving efficiency and reducing consumption while ensuring optimal lubrication performance.

[0063] S30, the transmission gear 43 drives the driven gear 44 to rotate based on a preset rotation rule.

[0064] Understandably, the transmission gear 43 drives the driven gear 44 to rotate along the first direction R, and then the transmission gear 43 drives the driven gear 44 to rotate along the second direction L. The speed of rotation in the first direction R is greater than the speed of rotation in the second direction L, ensuring sufficient and reliable lubrication and avoiding lubrication dead zones.

[0065] S40, the grease injection assembly 30 supplies grease to the outer peripheral side of the driven gear 44 based on a preset grease injection amount.

[0066] Specifically, the braking assembly 40 also includes an integrally formed support base 422, a first protective cover 423 and a second protective cover 424; the driven gear 44 and the transmission gear 43 are disposed on the support base 422; the first protective cover 423 and the second protective cover 424 surround the opposite sides of the transmission gear 43 and extend to the meshing point of the transmission gear 43 and the driven gear 44.

[0067] Step S40 further includes: when the transmission gear 43 drives the driven gear 44 to rotate circumferentially along the first direction R, some of the grease is squeezed out at the meshing point and falls into the first protective cover 423; when the transmission gear 43 drives the driven gear 44 to rotate circumferentially along the first direction L, some of the grease falls into the second protective cover 424.

[0068] Understandably, the preset grease injection amount ensures that the grease supply is matched in real time with the actual motion state and lubrication requirements of the driven gear 44 and the transmission gear 43, thus guaranteeing the lubrication effect of the braking assembly 40 and preventing grease buildup.

[0069] Furthermore, the first protective cover 423 and the second protective cover 424 are located on opposite sides of the outer circle of the transmission gear 43 in an arc shape. Based on the design of the first protective cover 423 and the second protective cover 424, the grease will not be splashed onto other parts of the brake assembly 40 when it moves along the first direction R or the first direction L. The grease that has detached from the transmission gear 43 and the driven gear 44 is controlled within the range of the first protective cover 423 and the second protective cover 424, so as not to affect the performance of other parts. The first protective cover 423 and the second protective cover 424 greatly ensure the cleanliness of the internal environment of the brake, thereby ensuring the yield of the brake.

[0070] S50, the driven gear 44 transfers grease to the transmission gear 43 along its outer circumference, completing the lubrication process. Please refer to [reference needed]. Figure 1 and Figure 2 Step S50 also includes steps S51-S53:

[0071] S51, based on the grease injection stop command, the grease injection assembly 30 stops supplying grease to the outer peripheral side of the driven gear 44.

[0072] S52, based on the preset rotation rules, the transmission gear 43 continues to drive the driven gear 44 to rotate circumferentially along the first direction R and the second direction L in sequence.

[0073] Understandably, after the grease injection assembly 30 stops supplying grease to the outer periphery of the driven gear 44, the braking assembly 40 utilizes the dual effects of rotational centrifugal force and meshing compression. Through the coordination of speed and the first and second grease injection amounts, it achieves uniform distribution of grease, significantly improving efficiency and reducing consumption while ensuring optimal lubrication.

[0074] S53, obtain the stop command for brake assembly 40, and brake assembly 40 completes lubrication.

[0075] S60, after lubrication is completed, the delivery assembly 10 moves the brake assembly 40 away from the grease injection assembly 30, so that the grease injection assembly 30 does not need to avoid the brake assembly 40.

[0076] Understandably, the grease injection head of the grease injection assembly 30 can remain stationary after supplying grease to the brake assembly 40. The brake assembly 40 is then moved away from the grease injection assembly 30 by the conveying assembly 10. This eliminates the need for the grease injection assembly 30 to perform a return action and the corresponding waiting time, directly shortening the lubrication cycle to its minimum and greatly improving the efficiency of lubrication and the overall efficiency of the production line.

The braking assembly 40 is mounted on the carrier tray 11, and the carrier tray 11 drives the braking assembly 40 to move along the grease injection assembly 30 toward the outer periphery of the driven gear 44 based on the conveyor belt.

[0084] The first protective cover 423 and the second protective cover 424 are arranged on opposite sides of the transmission gear 43 and extend toward the meshing point of the transmission gear 43 and the driven gear 44.

[0085] Specifically, the first protective cover 423 and the second protective cover 424 are arc-shaped and surround the opposite sides of the outer circle of the transmission gear 43, ensuring that the grease can fall into the first protective cover 423 or the second protective cover 424.
