[0001] The utility model relates to the technical field of electric motors, in particular to an electric and manual dual-purpose motor. Background Art

[0002] Most motors on the market are electrically driven, and the motors are started and stopped by powering on and off. In the case of a power outage, the motors cannot operate, and it is difficult to drive the actuators connected to them. In some special cases, the actuators need to continue to operate even in the event of an accidental power outage, which requires that the motors can be manually controlled in the event of a power outage. For this reason, an electric and manual dual-purpose motor is proposed. Utility Model Content

[0003] In order to solve the problem that most motors are difficult to control manually, the utility model provides an electric and manual dual-purpose motor, which is optimized and improved on the basis of a conical motor so that it can realize normal electric drive and can also be manually controlled to operate in the event of an unexpected power outage, thereby meeting normal application requirements in special circumstances.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] An electric and manual dual-purpose motor comprises a conical motor body and a brake mechanism arranged at the rear of the conical motor body, wherein the brake mechanism comprises a rear sealing cover, a half shaft, a brake assembly, a brake pot, a hand chain wheel and a hand chain;

[0006] The rear sealing cover is detachably arranged at the rear of the conical motor body, which facilitates the disassembly and assembly of the rear sealing cover. The half shaft is axially adjustable in the rear sealing cover to achieve axial movement of the half shaft. The half shaft and the motor shaft of the conical motor body are coaxially arranged front and back.

[0007] The brake assembly is fixedly arranged at the rear of the half-shaft, and the brake pot and the hand chain wheel are also rotatably arranged on the front of the half-shaft. The brake pot and the hand chain wheel are integrally formed on the left and right sides. The friction contact between the end face of the hand chain wheel and the brake assembly generates a certain friction torque. The hand chain is arranged on the hand chain wheel to facilitate the rotation of the hand chain wheel. The hand chain passes through the rear sealing cover to facilitate the operation of the hand chain by personnel.

[0008] The rear end of the motor shaft of the conical motor body is provided with a brake ring, which is arranged in the rear sealing cover. The brake ring extends into the brake pot and is in frictional contact with the brake pot, so as to facilitate the braking of the conical motor body.

[0009] Furthermore, the conical motor body comprises a motor housing, a front end cover, a rear end cover, the motor shaft, a brake ring, a conical rotor, a conical stator, a brake spring and a line box;

[0010] Both ends of the motor housing are bolted with the front end cover and the rear end cover respectively, which facilitates the disassembly and assembly of the front and rear end covers. The motor shaft is arranged between the front end cover and the rear end cover. The motor shaft is rotationally connected to the front end cover and the rear end cover through thrust bearings respectively, which can not only facilitate the rotation of the motor shaft but also enable its axial movement. A keyway is provided at the front end of the motor shaft extending out of the front end cover, and the rear end extends out of the rear end cover to connect the brake ring, driving the brake ring to rotate together. A rear seal cover is bolted behind the rear end cover.

[0011] Further, a conical rotor is arranged on the motor shaft inside the motor housing. A brake spring is sleeved on the motor shaft between the conical rotor and the front end cover, which facilitates the axial reset of the motor shaft after power-off. A conical stator is arranged on the inner wall of the motor housing, and the conical stator is sleeved outside the conical rotor. The conical tips of the conical stator and the conical rotor both face the front of the motor shaft. An inlet box is arranged outside the motor housing, which is convenient for wiring of the conical motor body.

[0012] Further, the rear seal cover includes a ring body and a cover. One end of the ring body is bolted behind the conical motor body, and the other end of the ring body is bolted with the cover. The cross-section of the combined connection of the ring body and the cover is in a "匚" shape, which is convenient for closing one end of the ring body. The open end of the rear seal cover faces forward towards the rear of the conical motor body, which is convenient for the brake ring to extend into the rear seal cover.

[0013] Further, an adjusting nut is bolted at the center of the closed end of the rear seal cover. The rear end of the half shaft is arranged inside the adjusting nut and is threadedly connected with the adjusting nut, which can facilitate the axial movement of the half shaft. The front end of the half shaft passes through the side wall of the rear seal cover forward and extends into the rear seal cover. The half shaft and the rear seal cover are coaxially arranged inside and outside.

[0014] Further, the braking assembly includes a half shaft support disc, a fixed brake disc, a spline sleeve, a spline plate, a pressing plate, friction plates and guide posts. The half shaft support disc is key-connected to the half shaft, and a fixed brake disc and a spline sleeve are also arranged on the half shaft.

[0015] Further, a brake drum, a hand chain wheel, a pressing plate and a spline plate are sequentially sleeved on the spline sleeve. Friction plates are arranged between the hand chain wheel and the pressing plate and between the pressing plate and the spline plate. The friction plates are sleeved on the spline sleeve, and the spline plate is key-connected to the fixed brake disc;

[0016] The hand chain wheel, the friction plates, the pressing plate, the spline plate, the fixed brake disc and the half shaft support disc are sequentially attached. A plurality of the guide posts are arranged through the pressing plate, the fixed brake disc and the half shaft support disc. The plurality of guide shafts are circumferentially distributed on the periphery of the half shaft, which is convenient for the connection and fixation of the three and avoids rotation.

[0017] Furthermore, a chain hole is provided on the rear sealing cover. The chain hole is a long hole, which is bent in a semicircular shape and arranged on the side wall of the rear sealing cover. The hand chain passes through the chain hole and extends to the outside of the rear sealing cover.

[0018] Through the above technical solution, the beneficial effects of the utility model are:

[0019] The utility model has a reasonable structural design. After the conical motor body is powered on, the motor shaft overcomes the pressure of the brake spring and generates axial movement, which drives the brake ring to separate from the brake mechanism, and the motor shaft can operate normally. After power failure, the motor shaft moves in the opposite direction under the action of the brake spring, driving the brake ring to rub against the brake mechanism, and the two generate friction torque, prompting the motor shaft to stop immediately, thereby realizing the electric operation of the conical motor body.

[0020] The brake mechanism of the utility model is generally composed of a half shaft, a brake pot, a hand chain wheel and a brake assembly. The brake pot and the hand chain wheel rotate on the half shaft, and the two are formed in one piece. The hand chain wheel is in friction contact with the brake assembly, and then the brake ring, the brake pot, and the brake assembly are tightly pressed in sequence to achieve the braking of the conical motor body. At the same time, a hand chain is arranged on the hand chain wheel, which can drive the conical motor body to operate by manually operating the hand chain in special circumstances such as power failure, meeting the use requirements of electric manual.

DETAILED DESCRIPTION

[0024] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings:

[0025] like Figure 1~Figure 2As shown, the electric and manual dual-purpose motor comprises a conical motor body 1 and a brake mechanism 2 arranged behind the conical motor body 1. The conical motor body 1 can operate automatically after being powered on, and the brake mechanism 2 is used to brake the conical motor body 1. At the same time, the brake mechanism 2 can be manually controlled, and the conical motor body 1 can be driven to operate when the power is off by manually controlling the brake mechanism 2.

[0026] The conical motor body 1 includes a motor housing 11, a front cover 12, a rear cover 13, a motor shaft 14, a brake ring 15, a conical rotor 16, a conical stator 17, a brake spring 18 and a line box 19. The motor housing 11 is a torus 5, and its circumferential surface is provided with heat dissipation fins. The front cover 12 and the rear cover 13 are bolted to the two ends of the motor housing 11, which facilitates the disassembly and assembly of the components, and the two ends of the motor housing 11 can be closed.

[0027] A motor shaft 14 is arranged between the front end cover 12 and the rear end cover 13. When installed, the motor shaft 14 is rotatably connected to the front end cover 12 and the rear end cover 13 through thrust bearings, and the motor shaft 14 can move axially. The front end of the motor shaft 14 extends out of the front end cover 12 and is provided with a keyway, through which an external actuator can be connected, so as to facilitate the operation of the actuator; the rear end of the motor shaft 14 extends out of the rear end cover 13 and is connected to the brake ring 15, and the motor shaft 14 and the brake ring 15 operate synchronously.

[0028] In order to realize the operation of the motor shaft 14, a conical rotor 16 is arranged on the motor shaft 14 in the motor housing 11. At the same time, a conical stator 17 is arranged on the inner wall of the motor housing 11. The conical stator 17 is sleeved outside the conical rotor 16. The cone tips of the conical stator 17 and the conical rotor 16 are both facing the front of the motor shaft 14. An incoming wire box 19 is arranged outside the motor housing 11 for wiring the conical motor body 1. In addition, a brake spring 18 is sleeved on the motor shaft 14 between the conical rotor 16 and the front end cover 12, and the brake spring 18 prompts the motor shaft 14 to generate an axial force.

[0029] The electric operation principle of the above conical motor body 1 is as follows: after power is turned on, a rotating magnetic field is generated between the conical rotor 16 and the conical stator 17, and an axial magnetic pulling force is generated, which causes the conical rotor 16 to move and rotate inside the conical stator 17, and then the motor shaft 14 overcomes the pressure of the brake spring 18 to move axially, so that the brake spring 18 is compressed, and the motor shaft 14 rotates driven by the conical rotor 16. After power is turned off, the rotating magnetic field disappears, and then under the action of the brake spring 18, the motor shaft 14 moves axially in the opposite direction and resets.

[0030] During the axial movement and circumferential rotation of the above motor shaft 14, the brake ring 15 will be driven to move axially and rotate circumferentially together. After power-off, the brake ring 15 will cooperate with the braking mechanism 2 to stop the motor shaft 14, and then the conical motor body 1 will be braked.

[0031] In this embodiment, the braking mechanism 2 includes a rear sealing cover 21, a half shaft 22, a braking component 23, a brake pot 24, a bracelet wheel 25 and a hand chain 26. The rear sealing cover 21 is equivalent to a housing that covers and protects each component in the braking mechanism 2. The rear sealing cover 21 is detachably arranged behind the conical motor body 1. Here, the rear sealing cover 21 is bolted behind the rear end cover 13, which facilitates the disassembly and assembly of the rear sealing cover 21.

[0032] In order to facilitate the installation of each component of the braking mechanism 2 into the rear sealing cover 21, the rear sealing cover 21 needs to be designed as a split type. Specifically, the rear sealing cover 21 includes a ring body 5 and a cover 6. Both ends of the ring body 5 are open. One end of the ring body 5 is bolted behind the conical motor body 1, and the other end of the ring body 5 is bolted with a cover 6. The cross-section of the ring body 5 and the cover 6 combined is in a "C" shape. Thus, the cover 6 can close the other end of the ring body 5, and the open end of the rear sealing cover 21 faces forward and towards the rear of the conical motor body 1.

[0033] The half shaft 22 is axially adjustable in the rear sealing cover 21. The half shaft 22 and the rear sealing cover 21 are coaxially arranged inside and outside, and the half shaft 22 and the motor shaft 14 of the conical motor body 1 are coaxially arranged front and back.

[0034] The axial adjustability of the half shaft 22 means that the half shaft 22 can move axially to adjust the gap between the brake ring 15 and the brake pot 24. Specifically, an adjusting nut 3 is bolted to the center of the closed end of the rear sealing cover 21, that is, the adjusting nut 3 is arranged at the center of the cover 6. The rear end of the half shaft 22 passes through the adjusting nut 3 and is threadedly connected to the adjusting nut 3. The front end of the half shaft 22 passes forward through the side wall of the rear sealing cover 21 and extends into the rear sealing cover 21.

[0035] On the premise of removing the bolts, by turning the adjusting nut 3, the axial movement of the half shaft 22 can be realized, and then the length of the half shaft 22 extending into the rear sealing cover 21 can be changed. When the half shaft 22 moves axially, the components on the half shaft 22 will also move together, and the half shaft 22 itself does not rotate.

[0036] The components on the half shaft 22 are as follows: A braking component 23 is fixedly arranged behind the half shaft 22, and a brake pot 24 and a bracelet wheel 25 are also rotatably arranged in front of the half shaft 22. The brake pot 24 and the bracelet wheel 25 are integrally formed left and right. When the half shaft 22 moves axially, it will drive the braking component 23, the brake pot 24 and the bracelet wheel 25 to move together.

[0037] The brake assembly 23 includes a half-shaft support disc 231, a fixed brake disc 232, a spline sleeve 233, a spline key 234, a pressure plate 235, a friction plate 236 and a guide column 237. The half-shaft support disc 231 is keyed to the half-shaft 22, so that the half-shaft support disc 231 itself cannot rotate, and the half-shaft 22 is also provided with a fixed brake disc 232 and a spline sleeve 233.

[0038] The spline sleeve 233 is sequentially sleeved with a brake pot 24, a hand chain wheel 25, a pressure plate 235 and a spline keypad 234. Friction plates 236 are arranged between the hand chain wheel 25 and the pressure plate 235, and between the pressure plate 235 and the spline keypad 234. The friction plates 236 are also sleeved on the spline sleeve 233. The spline keypad 234 and the fixed brake disc 232 are key-connected, and the two will not produce relative rotation. The above hand chain wheel 25, friction plates 236, pressure plate 235, spline keypad 234, fixed brake disc 232 and half-axle support disc 231 are sequentially fitted.

[0039] In order to achieve the coaxiality of the installation between the components, a plurality of guide posts 237 are provided between the pressure plate 235, the fixed brake disc 232 and the half-shaft support disc 231. The plurality of guide shafts are evenly distributed around the half-shaft 22, and the guide posts 237 and the three components are interference fit. Therefore, the guide posts 237 not only ensure the coaxiality of the installation between the three components, but also, under the premise that the half-shaft support disc 231 cannot rotate, the pressure plate 235 and the fixed brake disc 232 will not rotate either.

[0040] Since the rear end of the motor shaft 14 of the conical motor body 1 is provided with a brake ring 15, the brake ring 15 is arranged in the rear sealing cover 21. To realize the function of the brake ring 15, the brake ring 15 extends into the brake pot 24 and is in frictional contact with the brake pot 24, and at the same time, the end surface of the hand chain wheel 25 and the brake assembly 23 are in frictional contact, thereby braking the brake ring 15 and stopping the motor shaft 14.

[0041] Specifically, after the conical motor body 1 is powered on, the motor shaft 14 moves, causing the brake ring 15 to separate from the brake pot 24, and the two do not contact each other, thereby ensuring the normal operation of the motor shaft 14. After the power is turned off, the motor shaft 14 moves in the opposite direction, causing the brake ring 15 to enter the brake pot 24 and generate friction contact with the brake pot 24. At the same time, the hand chain wheel 25 and the brake assembly 23 are pressed tightly to generate friction torque, forcing the brake ring 15 to stop rotating immediately, and then the conical motor body 1 is braked instantly.

[0042] In order to ensure that the conical motor body 1 can still operate when the power is off, a hand chain 26 is provided on the hand chain wheel 25, and the hand chain 26 passes through the rear sealing cover 21. Specifically, a chain hole 4 is provided on the rear sealing cover 21, and the chain hole 4 is a long hole, and the chain hole 4 is bent in a semicircular shape and arranged on the side wall of the rear sealing cover 21. The hand chain 26 passes through the chain hole 4 and extends to the outside of the rear sealing cover 21.

[0043] The manual operation principle of the conical motor body 1 is: manually pull the hand chain 26 to drive the hand chain wheel 25 to rotate, and then the brake pot 24 will rotate together. Since the brake ring 15 and the brake pot 24 in the conical motor body 1 have friction contact after power failure, the brake pot 24 will drive the brake ring 15 to rotate, and the motor shaft 14 will run, thereby realizing the manual control operation of the conical motor body 1, meeting the use requirements in special circumstances.

[0044] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent scope of the present invention should be included in the patent application scope of the present invention.
