Description

Technical Field

[0001] This invention relates to the technical field of gearbox assembly equipment, specifically to a grease coating device for oil seal grooves. Background Technology

[0002] New energy transmissions are characterized by high input speeds. To meet the sealing requirements of the gearbox, the traditional single oil seal structure of the input shaft is changed to a double oil seal to improve the sealing performance of the gearbox. However, the double oil seal has a drawback: the oil seal near the outer edge cannot come into contact with the lubricating oil inside the gearbox due to the influence of the inner oil seal and cannot be effectively lubricated, resulting in dry friction and rapid failure. To solve this problem, grease is pre-applied to the groove of the oil seal near the outer edge. The lip of the oil seal is very thin and easily damaged, yet it is crucial to the sealing performance and requires high cleanliness. Existing manual grease application technology is time-consuming and labor-intensive. Furthermore, manual grease application is constrained by factors such as the skill level of the personnel, the intensity of their work, and the control of process cleanliness, making process control extremely unstable. Applying too much grease wastes grease, increases costs, and contaminates the product. Missing grease poses a serious quality risk, while applying too little does not meet the relevant technical requirements of the process. Uneven application violates the principle of process consistency and increases quality risks.

[0003] Therefore, there is an urgent need to develop an automated grease application device to ensure even and full grease application and eliminate the risk of contamination during the grease application process. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a grease coating device for oil seal grooves, which ensures uniform and full grease application and eliminates the risk of contamination during the grease coating process; furthermore, it is easy to operate and highly practical.

[0005] A grease coating device for oil seal grooves, characterized in that it comprises:

[0006] The equipment housing includes a base and a top cover, the top cover being fitted onto the upper surface of the base and forming an internal cavity;

[0007] The servo actuator system includes an ACK rotary cylinder, a servo motor, and electrical components;

[0008] Pressure tanks are used to store lubricating greases;

[0009] Pressure control system, used for controlling the pressure of lubricating grease;

[0010] And an oil seal placement mechanism, wherein an oil seal placement annular groove is provided on the upper part of the oil seal placement mechanism, and the oil seal placement mechanism is supported on one side of the upper cover plate by a bearing, and the oil seal placement annular groove is exposed.

[0011] The pressure tank is arranged on the other side of the built-in cavity. The servo motor is fixed in the built-in cavity. The lower part of the oil seal placement mechanism is connected to the servo motor. In the working state, the servo motor drives the oil seal placement mechanism to rotate at a constant speed. The cylinder seat of the ACK corner cylinder is fixed on the upper surface of the upper cover plate. The output end of the ACK corner cylinder is located directly above the oil seal placement annular groove. A grease hose is inserted into the outer end of the rotating arm of the ACK corner cylinder. In the working state, the ACK corner cylinder drives the grease hose to descend and align it with a radial position of the oil seal located in the oil seal placement annular groove. In the non-working state, the ACK corner cylinder rises and rotates, causing the grease hose to disengage from the surface area of ​​the oil seal placement annular groove.

[0012] Its further features are:

[0013] The electrical components include a 24V DC switching power supply, a 24V DC intermediate relay, a 5V DC time relay, two sets of 24V DC two-position three-way solenoid valves, and a button. The button is used to control the circuit on / off. The 24V DC switching power supply, the 24V DC intermediate relay, the 5V DC time relay, and the 24V DC two-position three-way solenoid valves are all located in the built-in cavity. The 24V DC switching power supply is connected to the 24V DC intermediate relay and the 5V DC time relay. The 24V DC intermediate relay is electrically connected to the two sets of 24V DC two-position three-way solenoid valves. The 5V DC time relay is electrically connected to the servo motor. The output end of one of the 24V DC two-position three-way solenoid valves is connected to the air circuit of the ACK rotary cylinder through a pipeline. The output end of the other 24V DC two-position three-way solenoid valve is connected to the air circuit of the pressure control system.

[0014] The electrical components also include an electronic speed controller, which is externally located on one side plate of the base and is used to control the rotation speed of the servo motor.

[0015] The electrical component also includes a charging interface, which is used to connect an external AC power supply for charging the DC 24V switching power supply.

[0016] The pressure control system includes a gas pressure gauge, a pressure regulating valve, and an exhaust valve;

[0017] The pressure tank includes a tank body and a top cover. The top cover is sealed to the upper part of the tank body by a silicone sealing ring and is fastened by fasteners with an outer circumferential cloth.

[0018] The upper cover is equipped with a pressure control system and a discharge pipe interface. The upper cover is connected to a pressure regulating valve and an exhaust valve. The pressure regulating valve is connected to a gas pressure gauge and an air pipe interface. External compressed gas flows into the pressure tank through a hose and the air pipe interface. The pressure of the gas entering the pressure tank is regulated by the regulating valve. The pressure control controls the flow rate of the lubricating grease. The lubricating grease flows out from the discharge pipe interface through the internal flow channel pipe. The discharge pipe interface is connected to the inlet end of the lubricating grease hose.

[0019] The base is also provided with a compressed gas connection interface on one side plate. The compressed gas connection interface flows into the main pipe through the gas path and is then distributed to the main gas path port of two sets of DC 24V two-position three-way solenoid valves.

[0020] With the above technical solution, the pressure tank is used to supply grease to the oil seal placed in the annular groove of the oil seal through the grease hose. When the oil seal is in place, the ACK rotary cylinder is driven to move the output end of the grease hose to a radial position of the oil seal, and the servo motor is driven to rotate, thereby driving the oil seal placement mechanism to rotate at a uniform speed. With the stable supply of grease through the grease hose, after the oil seal rotates uniformly a set number of times, the grease supply through the grease hose is cut off simultaneously. This ensures that the grease is applied evenly and fully, and eliminates the risk of contamination during the grease application process. In addition, it is easy to operate and highly practical.

[0031] Pressure tank 30 is used to store lubricating grease;

[0032] The pressure control system 40 is used to control the pressure of the grease. The pressure control system 40 includes a gas pressure gauge 41, a pressure regulating valve 42, and an exhaust valve 43.

[0033] The oil seal placement mechanism 50 is provided with an oil seal placement annular groove 51 on its upper part. The oil seal placement mechanism 50 is supported on one side of the upper cover plate 12 by bearings, and the oil seal placement annular groove 51 is exposed.

[0034] The pressure tank 30 is arranged in the other side of the built-in cavity 13. The servo motor 22 is fixed in the built-in cavity 13. The lower part of the oil seal placement mechanism 50 is connected to the servo motor 22. In the working state, the servo motor 22 drives the oil seal placement mechanism 50 to rotate at a constant speed. The cylinder seat of the ACK angle cylinder 21 is fixed on the upper surface of the upper cover plate 12. The output end of the ACK angle cylinder 21 is located directly above the oil seal placement annular groove 51. The outer end of the rotating arm 211 of the ACK angle cylinder 21 is inserted with a grease hose 60. In the working state, the ACK angle cylinder 21 drives the grease hose 60 to descend and align with a radial position of the oil seal located in the oil seal placement annular groove 51. In the non-working state, the ACK angle cylinder 21 rises and rotates, causing the grease hose 60 to be disengaged from the surface area of ​​the oil seal placement annular groove 21.

[0035] In a specific embodiment, the pressure tank 30 includes a tank body 31 and an upper cover portion 32. The upper cover portion 32 is sealed to the upper part of the tank body 31 by a silicone sealing ring and is fastened by fasteners 33 with an outer circumferential cloth.

[0036] The upper cover 32 is equipped with a pressure control system 40 and a discharge pipe interface 34. The upper cover 32 is connected to a pressure regulating valve 42 and an exhaust valve 43. The pressure regulating valve 42 is connected to a gas pressure gauge 41 and an air pipe interface 35. External compressed gas flows into the pressure tank 30 through a hose and an air pipe interface 35. The pressure of the gas entering the pressure tank 30 is regulated by the regulating valve 42. The pressure control controls the flow rate of the lubricating grease. The lubricating grease flows out from the discharge pipe interface 34 through an internal flow channel pipe. The discharge pipe interface 34 is connected to the inlet end of the lubricating grease hose 60.

[0037] A compressed gas connection interface is also provided on one side plate of the base 11. The compressed gas connection interface flows into the main pipe through the gas path and is then connected to the main gas path port of two sets of DC 24V two-position three-way solenoid valves 4. In a specific embodiment, the compressed gas connection interface is a straight-through valve 9.

[0038] Its working principle is as follows: Compressed air is connected to the straight-through valve of the equipment through a hose. After entering the equipment, the air path is divided into two parts through a three-way valve, which are respectively connected to two sets of two-position three-way solenoid valves. The two gas paths are respectively connected to the pressure tank and the ACK rotary cylinder. The coils of the solenoid valves used to control the gas on / off of the pressure tank and the solenoid valves used to control the gas on / off of the ACK rotary cylinder are connected to the normally open contact of the DC 24V intermediate relay. The coil of the DC 5V time relay is connected to the servo motor. The normally open contact of the DC 5V time relay is connected to the coil of the DC 24V intermediate relay to control the circuit on / off of the time relay. The DC 24V switching power supply powers the solenoid valves, time relay, and servo motor. The electronic speed controller controls the speed of the servo motor. Buttons control the power supply to the relay and servo motor. After pressing the control button, the servo motor is energized and rotates, and the DC 5V time relay coil is energized. When the set time is reached, the normally open contact of the DC 5V time relay closes, energizing the DC 24V intermediate relay coil and the two-position three-way solenoid valve. The ACK angle cylinder, along with the grease hose, rotates and presses down above the oil seal groove. At the same time, the grease in the pressure tank is squeezed out of the tank and flows along the hose to the top of the oil seal groove, completing the grease coating action on the oil seal groove. Releasing the button de-energizes the solenoid valve, releases the gas in the pressure tank, stops the grease flow, the ACK angle cylinder resets, and the servo motor is de-energized and stops rotating. This achieves precise control of the grease coating on the oil seal groove. The advantages of this equipment also include: semi-automatic control reduces the labor intensity of operators and improves production efficiency; the uniform and full grease in the oil seal groove is conducive to the stability of product quality; the grease is contaminated during the process in a sealed container; and precise time control helps to reduce product production costs.
