Description

Technical Field

[0001] The utility model relates to the technical field of solar panel transmission, in particular to a clutch mechanism for the input end of a speed reducer. Background Technique

[0002] Photovoltaic solar silicon panels are the core part of a solar power generation system and also the most valuable part of a solar power generation system. The function of photovoltaic solar silicon panels is to convert solar energy into electrical energy, and the electrical energy is sent to a storage battery for storage or directly used to drive a load to work. The quality and cost of photovoltaic solar silicon panels will directly determine the quality and cost of the entire solar power generation system.

[0003] The existing solar panel transmission system needs to drive the solar panel to turn by a motor through a speed reducer. However, the speed reducer cannot stop by itself after running, and it is necessary to rely on stopping the motor to make the speed reducer stop. The current technology is to install a clutch between the speed reducer and the output shaft, and the power transmission between the output shaft and the speed reducer is cut off by controlling the clutch, and then the motor is stopped. This method has a large loss to the motor and a short service life. Content of the Utility Model

[0004] The purpose of the utility model is to provide a clutch mechanism for the input end of a speed reducer to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A clutch mechanism for the input end of a speed reducer, including a motor and a speed reducer, and the shaft extension end of the motor is power-connected to the input shaft of the speed reducer through a clutch.

[0006] In the above technical solution, the power transmission between the input end of the speed reducer and the motor can be controlled to be cut off through the clutch. Since the power between the motor and the speed reducer is high-speed and low-torque, setting a clutch between the motor and the speed reducer has the effect of protecting the motor.

[0007] A pulley a is connected to the shaft extension end of the motor, a pulley b is connected to the input end of the speed reducer, and the pulley a and the pulley b are connected through a transmission belt.

[0008] In the above technical solution, the power between the motor and the input end of the speed reducer can be transmitted in the form of a transmission belt, which is convenient for long-distance power transmission between the shaft extension end of the motor and the input end of the speed reducer.

[0009] A gear a is connected to the shaft extension end of the motor, a gear b is connected to the input end of the speed reducer, and the gear a and the gear b are meshed for transmission.

[0010] In the above technical solution, power is transmitted between the motor and the input end of the speed reducer through the meshing of gear a and impact force b, so as to achieve a compact layout in space and improve the transmission efficiency.

[0011] The clutch adopted is an electronic clutch.

[0012] The electronic clutch includes a housing, a housing cover, a transmission wheel, a suction cup and a friction plate. The housing is sleeved on the input shaft through a bearing. The housing cover is sleeved outside the housing. An electromagnetic coil is provided on the inner side of the housing cover. The transmission wheel is installed on the housing through a bearing and a receiving groove is provided on the side of the transmission wheel. The housing cover communicating with the electromagnetic coil is movably inserted into the receiving groove. A friction plate a is provided on the side of the transmission wheel away from the receiving groove. The suction cup is circumferentially fixed and axially slidable on the main shaft. A friction plate b is provided on one side of the suction cup and an armature is embedded on the other side. A fixing block for limiting the suction cup is also provided on the input shaft. A spring piece abutting against the center of the suction cup is further provided at one end of the housing.

[0013] In the above technical solution, the adopted clutch has a transmission wheel and a suction cup. The transmission wheel and the suction cup can be excited by an electromagnetic coil, and then the armature is attracted to drive the friction plate a and the friction plate b to engage, so that the power of the transmission wheel is transmitted to the input shaft. When the electromagnetic coil is not powered on, the suction cup separates the friction plate a and the friction plate b under the action of the spring piece, thereby cutting off the power transmission between the transmission wheel and the input shaft.

[0014] It further includes a support frame. The motor and the speed reducer are respectively installed on the support frame through brackets.

[0015] A keyway is provided on the input shaft. A connecting key is provided in the keyway. A notch adapted to the keyway is provided on the flange of the suction cup. The length of the connecting key is less than the length of the notch. The fixing block presses the suction cup against the spring piece.

[0016] In the above technical solution, the keyway and the connecting key are provided to ensure that the suction cup can axially displace along the input shaft. The length of the connecting key is less than the length of the notch, which avoids interference between the fixing block and the connecting key.

[0017] The technical effects and advantages of the present utility model:

[0018] 1. In this solution, the power transmission between the input end of the speed reducer and the motor can be controlled to be cut off through the clutch. Since the power between the motor and the speed reducer is high-speed and low-torque, setting a clutch between the motor and the speed reducer has the effect of protecting the motor.

[0019] 2. In this solution, power can be transmitted between the motor and the input end of the speed reducer in the form of a transmission belt, which is convenient for long-distance power transmission between the shaft extension end of the motor and the input end of the speed reducer.

Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment 1

[0027] This embodiment provides a clutch mechanism for the input end of a speed reducer as shown in Figure 1 . The clutch mechanism includes a motor 2 and a speed reducer 3. The shaft extension end of the motor 2 is power-connected to the input shaft 31 of the speed reducer 3 through a clutch 4. In this embodiment, the clutch 4 can be used to control the cut-off of the power transmission between the input end of the speed reducer 3 and the motor 2. Since the power between the motor 2 and the speed reducer 3 is high-speed and low-torque, setting the clutch 4 between the motor 2 and the speed reducer 3 has the effect of protecting the motor 2.

[0028] Specifically, the transmission method between the input end of the speed reducer 3 and the shaft extension end of the motor 2 is belt transmission. The shaft extension end of the motor 2 is connected with a pulley a 5, and the input end of the speed reducer 3 is connected with a pulley b 6. The pulley a 5 and the pulley b 6 are connected through a transmission belt. The power between the motor 2 and the input end of the speed reducer 3 can be transmitted by means of a transmission belt, which is convenient for the long-distance transmission of power between the shaft extension end of the motor 2 and the input end of the speed reducer 3.

[0029] Embodiment 2

[0030] The difference between this embodiment and Embodiment 1 is that a gear a 7 is connected to the shaft extension end of the motor 2, and a gear b 8 is connected to the input end of the speed reducer 3. The gear a 7 and the gear b 8 are meshed for transmission. Power is transmitted between the motor 2 and the input end of the speed reducer 3 through the meshing of the gear a 7 and the impact force b, so as to achieve a compact layout in space and improve the transmission efficiency.

[0031] Further, in this embodiment, the transmission gear is a gear.

[0032] In the above Embodiment 1 and 2, the clutch 4 is an electronic clutch 4. As Figure 3 and Figure 4 shown, the electronic clutch 4 of this embodiment includes a housing 41, a housing cover 42, a transmission wheel 43, a suction cup 44 and a friction plate. The housing 41 is sleeved on the input shaft 31 through a bearing. The housing cover 42 is sleeved outside the housing 41. An electromagnetic coil 42-1 is provided on the inner side of the housing cover 42. The transmission wheel 43 is installed on the housing 41 through a bearing and a receiving groove is provided on the side of the transmission wheel 43. The housing cover 42 is inserted into the receiving groove in communication with the electromagnetic coil 42-1. A friction plate a 45-1 is provided on the side of the transmission wheel 43 away from the receiving groove. The suction cup 44 is circumferentially fixed and axially slidable with the main shaft. A friction plate b 45-2 is provided on one side of the suction cup 44, and an armature 46 is embedded on the other side. A fixing block 47 for limiting the suction cup 44 is also provided on the input shaft 31. A spring piece 48 that abuts against the center of the suction cup 44 is further provided at one end of the housing 41.

[0033] Further, the adopted clutch 4 has a transmission wheel 43 and a suction cup 44. The transmission wheel 43 and the suction cup 44 can be excited by the electromagnetic coil 42-1, and then attract the armature 46 to drive the friction plate a 45-1 and the friction plate b 45-2 to engage, so that the power of the transmission wheel 43 is transmitted to the input shaft 31. When the electromagnetic coil 42-1 is not energized, the suction cup 44 separates the friction plate a 45-1 and the friction plate b 45-2 under the action of the spring piece 48, thereby cutting off the power transmission between the transmission wheel 43 and the input shaft 31. It also includes a support frame 1, and the motor 2 and the speed reducer 3 are respectively installed on the support frame 1 through brackets.

[0034] Again, as Figure 4 shown, a keyway is provided on the input shaft 31, a connecting key 49 is provided in the keyway, a notch adapted to the keyway is provided on the flange of the suction cup 44, and the length of the connecting key 49 is less than the length of the notch. The fixing block 47 presses the suction cup 44 against the spring piece 48. Further, by providing the keyway and the connecting key 49, it is ensured that the suction cup 44 can axially displace along the input shaft 31, and the length of the connecting key 49 is less than the length of the notch, which avoids interference between the fixing block 47 and the connecting key 49.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
