[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0019] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside” are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0020] A heavy-duty electric floor spring door opener, such as Figure 1 、 2 As shown, it includes a motor 1 and a gear transmission group 2; the motor 1 and the gear transmission group 2 are arranged in a housing 3; the motor 1 is arranged vertically to the controller, and the motor 1 drives the fixed wheel 1-1 below, and the fixed wheel 1-1 cooperates with the transmission output wheel 4 through the gear transmission group 2; an angular contact bearing 5 is provided below the output wheel 4 to cooperate with supporting the output shaft 6.
[0021] Specifically, by arranging the motor 1 perpendicular to the controller and directly driving the fixed wheel 1-1 below, the power transmission path is optimized, energy loss during transmission is reduced, and overall efficiency is improved. At the same time, the precise coordination of the gear transmission group 2 ensures that power is smoothly and efficiently transmitted to the output wheel 4. The output shaft 6 is supported by an angular contact bearing 5, which enhances the support stability and rotation accuracy of the output shaft. The angular contact bearing can withstand large radial and axial loads, reduce vibration and noise, and extend the service life of the equipment. As a heavy-duty electric floor spring door opener, the load requirements are fully considered. By optimizing the configuration of the gear transmission group and the motor, it is ensured that the equipment can easily cope with the opening and closing of heavy doors. It is suitable for commercial, industrial and other places that require heavy doors. Since the main components such as the motor and gear transmission group are all arranged in the housing 3, it helps to protect the internal components from erosion by external environment such as dust and moisture. At the same time, the reasonable layout also facilitates technicians to carry out daily maintenance and servicing work.
[0022] As a preferred embodiment of the above, Figure 3 As shown, a protective cover 3 - 1 is provided above the shell 3 .
[0023] Specifically, the protective cover 3-1 can effectively isolate dust, moisture and other impurities in the external environment from entering the shell, thereby protecting key components such as the motor and gear transmission group from damage and extending the service life of the equipment. At the same time, the protective cover can provide a safe barrier to prevent direct contact by users or maintenance personnel, reducing the risk of electric shock, and using the same material and color as the shell, making the overall appearance of the door opener more unified and neat, thereby improving the overall aesthetics of the equipment.
[0024] As a preferred embodiment of the above, Figure 3 As shown, an output shaft protection cover 3 - 2 is provided above the protection cover 3 - 1 and around the output shaft 6 .
[0025] As a preferred embodiment of the above, Figure 3 As shown, a detachable shell upper cover 3-3 is provided between the shell 3 and the protective cover plate 3-1.
[0026] Specifically, a detachable shell cover 3-3 is provided between the shell 3 and the protective cover 3-1, and the output shaft protective cover 3-2 is specifically used to protect the output shaft position, effectively preventing external impurities, moisture, etc. from directly contacting the output shaft, reducing wear and corrosion, and extending the service life of the output shaft. The output shaft protective cover 3-2 and the protective cover 3-1 and the shell 3 are usually designed with the same material and color, making the overall appearance of the door opener more unified and neat, thereby improving the overall aesthetics of the equipment.
[0027] As a preferred embodiment of the above, Figure 3 As shown, the output shaft 6 is connected to the widened door opening arm 6-1.
[0028] As a preferred embodiment of the above, Figure 3 As shown, the output shaft 6 and the widened door opening arm 6-1 are fixed together by a groove and a rounded rectangular block 6-2.
[0029] Specifically, by widening the door opening arm 6-1, it has a larger cross-sectional area than traditional door opening arms, thereby improving its load-bearing capacity and bending strength. This allows the door opener to more easily handle the opening and closing of heavy doors, extending the service life of the equipment. Through the cooperation of the groove and the rounded rectangular block 6-2, it is possible to achieve precise positioning and fixation between the output shaft 6 and the widened door opening arm 6-1, ensuring a firm and reliable connection between the door opening arm and the output shaft, reducing failures and safety hazards caused by looseness or misalignment. The cooperation of the groove and the rounded rectangular block 6-2 not only strengthens the connection strength between the door opening arm and the output shaft, but also improves the overall strength of the entire door opener structure, making the door opener more stable and reliable when subjected to external forces, extending the service life of the equipment.
[0030] As a preferred embodiment of the above, Figure 2 As shown, the second wheel of the gear transmission group 2 is arranged above the first wheel, the first wheel is in horizontal contact with the fixed wheel 1-1, and the third wheel is arranged below the second wheel and the output wheel and is higher than the first wheel and the fixed wheel 1-1.
[0031] Specifically, by positioning the second wheel of the gear transmission assembly 2 above the first wheel, with the first wheel in horizontal contact with the fixed wheel 1-1, and the third wheel below the second wheel and the output wheel and above the first wheel and the fixed wheel 1-1, the gear transmission assembly is effectively utilized vertically, reducing horizontal space usage and making the entire door opener more compact. This is particularly important in environments with limited installation space, helping to improve the adaptability and flexibility of the device and achieve more uniform force distribution. During the transmission process, the forces borne by each gear are rationally distributed and transmitted, reducing wear and damage caused by uneven force.
[0032] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
