Description

Technical Field

[0001] The invention relates to the technical field of hydraulic machinery, in particular to a new motor with a clutch function. Background Art

[0002] A certain number of spillway tunnels have been built in the water storage dam of the hydroelectric power station. Their function is to open the gates to discharge floodwater when the upstream flood comes and the water level exceeds the limit (opening the gates is a necessary action in emergency situations). Under normal water level conditions, the gates of the spillway tunnels are closed. When they need to be opened, the electric control box controls the motor to get power, which is decelerated by the reducer, driving the fixed winch drum to rotate, and using the wire rope to lift (drop) the gate to open (close) the gate. The flood discharge gate is wide, and it is necessary to set up lifting points on both sides, and use two wire ropes to lift and close it at the same time. Each wire rope is lifted and lowered by a separate fixed winch, so the equipment is called: fixed-winding double-lifting-point hoist.

[0003] When the flood discharge gate fixed coil double lifting point hoist equipment encounters the following three accident conditions: (1) power supply interruption; (2) PLC electric control box control system damage; (3) motor short circuit. At this time, the hoist will not work, and the gate cannot be opened within a certain period of time. For example, during the flood season, it will cause flooding and even the danger of dam collapse, seriously threatening the lives and property of towns and people upstream and downstream.

[0004] The relevant reference CN202108032U discloses an emergency operation device and gate system for a winch hoist, wherein the clutch is connected to the power output shaft of the hydraulic pump type hydraulic motor body, and the output end of the clutch is used to connect the motor output shaft or the reducer input shaft of the winch type hoist, and the clutch can engage or disconnect the connection between the power output shaft of the hydraulic pump type hydraulic motor body and the motor output shaft or the reducer input shaft of the winch type hoist. The portable fuel hydraulic pump station generates pressure oil to drive the hydraulic pump type hydraulic motor body to rotate and drive the gate to open.

[0005] According to the above references and the actual situation at this stage, the connection between the actuator of the non-electric emergency operation equipment and the gate hoist is: the clutch is connected to the power output shaft of the hydraulic pump type hydraulic motor body, and the output end of the clutch is used to connect the motor output shaft or the reducer input shaft of the winch type gate hoist. The specific connection method is: the output shaft of the motor body is connected to the input shaft of the clutch through the first coupling, and the output shaft of the clutch is connected to the motor output shaft or the reducer input shaft through the second coupling, that is, the connection sequence is: motor body-coupling I-clutch-coupling II-motor or reducer. This structure shows that the three components (motor body, clutch, motor or reducer) are connected into a rigid structure through two couplings. Therefore, such a structure has the following defects: complex connection method, large spatial position, poor coaxiality, reduced operating stability, and high cost. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a new motor with clutch function, which simplifies the mechanical structure, saves space, improves coaxiality, has high operating stability, and saves manufacturing costs. At the same time, the motor is a special motor for the emergency equipment of the hydropower station gate hoist, and the application occasion is: when the motor is working, the clutch must be closed, and when the motor stops working, the clutch is disengaged.

[0007] In order to solve the above technical problems, the present invention provides a new type of motor with clutch function, including a motor body, a clutch mechanism and a motor output shaft; the motor body and the clutch mechanism are fixedly installed together; the clutch mechanism includes a clutch housing, and the clutch housing is installed with a motor inner shaft through a bearing; the motor inner shaft passes through the cylinder body; the motor inner shaft is splined to the inner shaft friction plate; there are multiple inner shaft friction plates arranged in parallel, and the inner shaft friction plates are placed on the outer sleeve friction plates; the outer sleeve friction plates are splined to the rotating outer sleeve; the rotating outer sleeve is rotatably installed in the clutch housing; a sealing end cover is fixedly installed at the open end of the clutch housing, and the motor output shaft is arranged in the sealing end cover; the motor output shaft is T-shaped, the base is fixedly connected to the rotating outer sleeve, and the rotating shaft passes through the sealing end cover; a groove is provided on the base, a spring seat is installed in the groove, and a reset spring is installed in the spring seat; a friction plate retaining ring is provided at the end of the outer sleeve friction plate, and the friction plate retaining ring is in contact with the reset spring.

[0008] By adopting the above technical solution, the original three parts of the motor body, hydraulic clutch and coupling are integrated into an integrated actuator: a motor with a hydraulic clutch. A reset spring is installed on the base of the motor output shaft. When high-pressure oil is input, the oil cylinder moves downward, generating axial pressure, compressing the reset spring and pressing the inner and outer friction plates and friction plate retaining rings, generating friction. The torque generated by the motor body is transmitted to the rotating outer sleeve through friction, and finally output by the motor output shaft to complete the clutch closing and torque transmission. It not only simplifies the mechanical structure and saves space, but also improves coaxiality, increases operating stability, and saves production costs. Most importantly, in the case of emergency flood discharge, the clutch closing operation step is reduced, and precious flood discharge time is gained.

[0009] Preferably, a high pressure port A, a high pressure port B and an oil drain port L are provided on the motor body.

[0010] By adopting the above technical solution, the high-pressure oil injected through the high-pressure ports A and B directly acts on the driving mechanism inside the motor body, generating a driving torque to rotate the inner shaft of the motor.

[0011] Preferably, the motor body is a plunger cylinder structure, and the cylinder rotates after high-pressure oil is input.

[0012] By adopting the above technical solution, the plunger cylinder structure can withstand higher hydraulic pressure, output high torque and operate stably.

[0013] Preferably, the inner shaft of the motor is a through shaft, passing through the motor body and the clutch mechanism.

[0014] By adopting the above technical solution, the torque output from the motor body is transmitted.

[0015] Preferably, an external spline is arranged on the inner shaft of the motor, and an internal spline is arranged on the inner ring of the inner shaft friction plate, and the external spline and the internal spline are meshed with each other.

[0016] By adopting the above technical solution, the outer spline is directly meshed with the inner spline, and when the cylinder sealing cavity moves downward after the pressure oil enters, the inner shaft friction plate can move axially along the spline.

[0017] Preferably, the inner wall of the rotating outer sleeve is provided with an inner spline, and the outer ring of the friction plate retaining ring is provided with an outer spline, and the two are connected by the spline.

[0018] By adopting the above technical solution, when the cylinder body generates a downward force after the pressure oil enters the cylinder sealing chamber, the outer sleeve friction plate can move axially along the spline. This action process will press the inner shaft friction plate together to form a friction force that can transmit torque.

[0019] Preferably, the inner shaft friction plate and the outer sleeve friction plate are placed adjacent to each other with a spacing therebetween, and are in normal contact with each other without being subjected to pressure.

[0020] By adopting the above technical solution, in the case of no pressure control oil input, no friction force will be generated between the outer sleeve friction plate and the inner shaft friction plate.

[0021] Preferably, sealing grooves are respectively arranged on the inner and outer sides of the oil cylinder body, and the oil cylinder body is sealed with the motor inner shaft and the clutch housing respectively through sealing members; and an oil cylinder sealing chamber is formed between the oil cylinder body, the clutch housing and the motor inner shaft.

[0022] By adopting the above technical solution, the cooperation of the sealing groove and the sealing element can ensure that a cylinder sealing cavity is formed between the cylinder body, the inner shaft of the motor and the clutch housing, thereby preventing oil leakage and ensuring the safe and reliable operation of the cylinder body.

[0023] Preferably, bearing stops are arranged on the outer sides of both ends of the rotating outer sleeve, and bearings are mounted on the bearing stops; and the bearings are fixed in the clutch housing.

[0024] By adopting the above technical solution, the rotating outer sleeve is installed in the clutch housing through the bearing, and the coaxiality is guaranteed by machinery, thereby ensuring the coaxiality of the motor inner shaft and the output shaft.

[0025] Preferably, a control oil port is provided on the clutch housing at the oil cylinder sealing chamber.

[0026] By adopting the above technical solution, it is easy to control the injection of pressure oil in the oil cylinder sealing cavity, which is beneficial to quickly transfer the energy of the pressure oil to the oil cylinder body, thereby promoting the rapid and stable movement of the oil cylinder body.

[0027] Preferably, sealing grooves are provided on the inner and outer sides of the sealing end cover, and the sealing end cover is sealed with the motor output shaft and the clutch housing through a sealing member.

[0028] By adopting the above technical solution, the sealing end cover, the motor output shaft and the clutch housing are sealed and connected. The sealed connection can effectively prevent external impurities (such as dust, moisture, etc.) from invading the interior of the clutch housing, avoid these impurities from damaging the internal parts of the clutch housing, and extend the service life of the motor.

[0029] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention integrates the original motor body, hydraulic clutch and coupling into one integrated actuator: a motor body with a hydraulic clutch. A reset spring is installed on the base of the motor output shaft. When high-pressure oil is input, the oil cylinder moves downward, generating axial pressure, compressing the reset spring and pressing the inner and outer friction plates and friction plate retaining rings to generate friction. The torque generated by the motor body is transmitted to the rotating outer sleeve through friction, and finally output by the motor output shaft to complete the clutch closing and torque transmission. In actual use, this mechanism simplifies the mechanical structure, saves space, improves coaxiality, has high operating stability, and saves manufacturing costs. Most importantly, in the case of emergency flood discharge, it reduces the clutch closing operation step, thereby gaining precious flood discharge time.

[0030] 2. The rotating outer sleeve and the friction plate retaining ring of the present invention are connected by splines. When the cylinder body generates a downward force after the pressure oil enters the cylinder sealing chamber, the outer sleeve friction plate can move axially along the splines. This action process presses the outer sleeve friction plate and the inner shaft friction plate together to form a friction force that can transmit torque.

[0031] 3. The oil cylinder body of the present invention is sealed with the motor inner shaft and the clutch housing respectively through sealing grooves and sealing members; a cylinder sealing chamber is formed between the oil cylinder body and the clutch housing to ensure the sealing between the oil cylinder body and the motor inner shaft and the clutch housing, prevent oil leakage, and ensure the safe and reliable operation of the oil cylinder body.

[0034] like Figure 1 As shown, a new type of motor with clutch function is composed of three parts: (i) motor body 14; (ii) clutch mechanism 17; (iii) motor output shaft 8. The outer shell of the motor body 14 and the outer shell of the clutch mechanism 17 are fixedly installed together. The motor body 14 is a plunger cylinder structure, and the cylinder rotates after high-pressure oil is input.

[0035] like Figure 2As shown, the clutch mechanism 17 includes a clutch housing 2, and the clutch housing 2 is installed with a motor inner shaft 1 through a bearing. The motor inner shaft 1 is a through shaft, which passes through the motor body 14 and the clutch mechanism 17, and transmits the torque output from the motor body. The motor inner shaft 1 passes through the oil cylinder body 3; the motor inner shaft 1 is spline-connected with the inner shaft friction plate 7; the inner shaft friction plate 7 is arranged in parallel. The inner shaft friction plate 7 and the outer sleeve friction plate 5 are placed adjacently and spaced apart, and the two are in normal contact without pressure. The outer sleeve friction plate 5 is spline-connected with the rotating outer sleeve 6; the rotating outer sleeve 6 is fixedly installed in the clutch housing 2 through two bearings and rotates; the open end of the clutch housing 2 is installed with a sealing end cover 9 by screws, and the motor output shaft 8 is arranged in the sealing end cover 9; the motor output shaft 8 is T-shaped, the base 18 is fixedly connected with the rotating outer sleeve 6, and the rotating shaft passes through the sealing end cover 9; a groove is provided on the base 18, and a spring seat 10 is installed in the groove, and a reset spring 11 is installed in the spring seat 10. A friction plate retaining ring 12 is provided at the end of the outer sleeve friction plate 5, and the friction plate retaining ring 12 is in direct contact with the reset spring 11. The present application integrates the motor body 14, the clutch mechanism 17, and the coupling (used to connect the motor body 14 and the clutch mechanism 17), which originally belonged to three components, into one, forming an integrated actuator: a motor with a hydraulic clutch. A reset spring 11 is installed on the base 18 of the motor output shaft 8. When high-pressure oil is input, the oil cylinder body 3 moves downward, generating axial pressure, compressing the reset spring 11 to press the inner and outer friction plates and the friction plate retaining ring 12, generating friction force, and the torque generated by the motor body is transmitted to the rotating outer sleeve 6 through the friction force, and finally output by the motor output shaft 8, completing the clutch closing and torque transmission. In actual use, this mechanism simplifies the mechanical structure, saves space, improves coaxiality, increases operating stability, and saves manufacturing costs. Most importantly, in the case of emergency flood discharge, the clutch closing operation step is reduced, and precious flood discharge time is gained.

[0036] like Figure 1 As shown, the motor body 14 has two high-pressure ports A and B and one oil drain port L: high-pressure oil enters from A and exits from B (or enters from B and exits from A), driving the motor inner shaft 1 to rotate forward (or reverse), and the generated leakage oil returns to the oil tank through the oil drain port L. The high-pressure oil injected through the high-pressure ports A and B directly acts on the driving mechanism inside the motor body, generating a strong driving torque to rotate the motor inner shaft 1.

[0037] The clutch mechanism 17 has a control oil port 13 on the clutch housing 2 at the oil cylinder sealing chamber 15, which is convenient for controlling the injection of pressure oil in the oil cylinder sealing chamber 15, and is conducive to quickly transferring the energy of the pressure oil to the oil cylinder body, promoting the rapid and stable movement of the oil cylinder body. When the control oil is input (or discharged), the clutch mechanism 17 generates a clutch function, and the motor inner shaft 1 and the motor output shaft 8 are clutched.

[0038] like Figure 2 As shown, in order to realize the clutch function, a clutch housing 2 needs to be designed to fix one end of the motor inner shaft 1 through a bearing.

[0039] In order to realize the clutch function, it is necessary to design a clutch housing 2 to connect and fix the clutch mechanism 17 and the motor body 14 to form a whole.

[0040] In order to realize the clutch function, it is necessary to design a clutch housing 2 and assemble the parts of the clutch mechanism 17 therein.

[0041] An external spline is arranged on the inner shaft 1 of the motor.

[0042] The inner shaft friction plate 7 is provided with an inner spline and assembled on the outer spline of the motor inner shaft 1. The motor inner shaft 1 and the inner shaft friction plate 7 are directly meshed with the inner spline through the outer spline, and when the cylinder body 3 moves downward, the inner shaft friction plate 7 can move axially along the spline.

[0043] It is necessary to design a rotating outer sleeve 6, the inner side wall of the rotating outer sleeve 6 is provided with an inner spline, and bearing stops are provided at both ends of the outer side wall.

[0044] The outer sleeve friction plate 5 is provided with an external spline, and the outer sleeve friction plate 5 is installed on the inner side of the rotating outer sleeve 6. The rotating outer sleeve 6 and the friction plate retaining ring 12 are spline-connected. When the oil cylinder body 3 moves downward, the outer sleeve friction plate 5 can move axially along the spline, and this action is pressed together with the inner shaft friction plate 7 to form a friction force that can transmit torque.

[0045] The bearing is installed at the bearing position outside the rotating outer sleeve 6, and the bearing is fixed in the clutch housing 2. The rotating outer sleeve is installed in the clutch housing 2 through the bearing, and the coaxiality is ensured by machinery to ensure the coaxiality of the motor inner shaft and the output shaft.

[0046] The inner shaft friction plate 7 and the outer sleeve friction plate 5 are installed at intervals.

[0047] In order to realize the clutch function, the oil cylinder body 3 needs to be designed, and sealing grooves are respectively provided inside and outside the oil cylinder body 3, and the oil cylinder sealing chamber 15 is formed with the motor inner shaft 1 and the clutch housing 2 through the sealing member, thereby forming the oil cylinder function. The cooperation of the sealing groove and the sealing member can ensure that the oil cylinder sealing chamber 15 is formed between the oil cylinder body and the motor inner shaft and the clutch housing, thereby preventing oil leakage and ensuring the safe and reliable operation of the oil cylinder body.

[0048] The motor output shaft 8 and the rotating sleeve 6 are fixed by bolt connection to form a rigid connection and maintain coaxial rotation.

[0049] like Figure 3 As shown, a groove is designed on the base 18 of the motor output shaft 8 for fixing the spring seat 10. A return spring 11 is installed in the spring seat 10.

[0050] The return spring 11 is separated from the friction plate by a friction plate retaining ring 12. The friction plate retaining ring 12 is provided with an external spline, and the friction plate retaining ring 12 is spline-connected with the rotating outer sleeve 6. A groove is provided on the bottom surface of the friction plate retaining ring 12 for limiting the return spring 11.

[0051] After all parts are installed, the sealing end cover 9 is fixed to the clutch housing 2 with screws, and sealing grooves are provided inside and outside the sealing end cover 9. The sealing member 16 is installed in the sealing grooves inside and outside the sealing end cover 9 to form a seal between the sealing end cover 9, the motor output shaft 8, and the clutch housing 2, which can effectively prevent foreign impurities (such as dust, moisture, etc.) from invading the interior of the clutch housing 2, avoid these impurities from damaging the internal parts of the clutch housing 2, and extend the service life of the motor body.

[0052] When there is no pressure control oil input, no axial pressure is generated between the cylinder body 3, the inner and outer friction plates, the friction plate retaining ring 12, and the return spring 11, and no friction force is generated between the inner and outer friction plates, and the clutch is in a disengaged state.

[0053] like Figure 4 As shown, when pressure oil is input into the control oil port 13, the oil cylinder body 3 is pushed downward, compressing the reset spring 11. At the same time, the inner and outer friction plates are subjected to axial pressure to generate friction. When the high-pressure oil drives the inner shaft 1 of the motor to rotate, the torque will be transmitted to the rotating outer sleeve 6 through the friction force, and finally output by the motor output shaft 8, completing the clutch closing and torque transmission.

[0054] After the control oil port 13 is emptied, the inner and outer friction plates and the oil cylinder body 3 are reset to their original positions due to the reset of the reset spring 11. Without the pressure oil pressure, the pressure between the inner and outer friction plates approaches zero, and no friction is generated, and the clutch is restored to the disengaged state.

[0055] The spring seat 10 not only serves to install the return spring 11 , but also serves to limit the downward running distance of the oil cylinder body 3 .

[0056] like Figure 5 As shown, under normal water level conditions, the gate of the flood discharge tunnel of the hydropower station is closed. When it needs to be opened, the electric control box controls the motor to be powered and decelerated by the reducer. Under this normal condition, the clutch mechanism 17 in the motor body of the actuator (with clutch) of the powerless emergency equipment is in a non-working state, that is, a separated state, the motor body 14 is separated from the motor output shaft 8, the fixed-winding double-hanging-point hoist is separated from the powerless emergency equipment, and the hoist operates independently and normally.

[0057] In special circumstances, it is necessary for non-electric emergency equipment to participate in the work. When the non-electric emergency equipment power station outputs high-pressure oil, the high-pressure oil is divided into two paths, one path is input into the motor body 14, and the other path is input into the accumulator and clutch mechanism 17 through the pressure reducing valve and the one-way valve. While the high-pressure oil drives the motor body 14 to rotate, the clutch mechanism 17 is in a closed working state. The motor body 14 forms a rigid connection with the motor output shaft 8, driving the fixed winch drum to rotate, and the wire rope lifts (drops) the gate to open (close) the gate. And because of the one-way valve and accumulator, the hydraulic oil stored in the accumulator keeps the motor body 14 in the closed position at all times, regardless of whether the motor body is in forward rotation, forward rotation, or stopped state. Only after the accident state is over, the stop valve is opened, the accumulator is depressurized, and the clutch mechanism 17 can be separated.

[0058] The new motor with clutch function of the present application closes the motor body 14 and the motor output shaft 8 to form a rigid connection as long as high-pressure oil is input. When the power-off emergency device does not need to work, manual operation is required to separate the motor body 14 from the motor output shaft 8.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
