The present application proposes a transmission shaft mounting structure, and a detailed description will be given below of the transmission shaft mounting structure in connection with an air conditioner indoor unit. It is to be understood that the transmission shaft mounting structure disclosed in the present application is not limited to application to an air conditioning indoor unit, but may be applied to other similar products requiring support of the transmission shaft 4000.
Referring to fig. 1 to 4 and fig. 7, in some embodiments of the present application, a transmission shaft mounting structure includes a bracket 1000, a bearing seat 2000, a bearing 3000 and a transmission shaft 4000, and by the mutual cooperation of the bracket 1000, the bearing seat 2000, the bearing 3000 and the transmission shaft 4000, the mounting difficulty of the transmission shaft 4000 is reduced, the mounting efficiency is improved, and the effective supporting and positioning of the transmission shaft 4000 is realized.
In a large-scale indoor unit of an air conditioner, there are multiple wind wheels 6200 in general, in order to realize the driving of multiple wind wheels 6200, for example, a separate motor 6100 is provided for each wind wheel 6200, that is, the wind wheels 6200 and the motors 6100 are in one-to-one correspondence, and the rotation of all the wind wheels 6200 is realized through the driving of each motor 6100, but this way has a great disadvantage that the cost of a single motor 6100 is high, if the motor 6100 is configured for each wind wheel 6200, the cost of the whole product is greatly increased, and the weight of the motor 6100 is heavy, so that the whole indoor unit of the air conditioner is too heavy, which is unfavorable for the hoisting operation of the indoor unit of the air conditioner. Another way is to provide a motor 6100, where the motor 6100 realizes synchronous rotation of all wind wheels 6200 in a transmission manner, which can greatly reduce cost and weight of the product.
Specifically, in the present embodiment, at least two wind wheels 6200 may be connected by a transmission shaft 4000, and the transmission shaft 4000 is in driving connection with a motor 6100, and the transmission shaft 4000 can drive the wind wheels 6200 to rotate under the action of the motor 6100. It will be appreciated that the connection between the drive shaft 4000 and the motor 6100 is a power transmission connection, for example, transmission is achieved by a coupling, and of course, other manners may be adopted, so long as it is ensured that the power output by the motor 6100 can be transmitted to the drive shaft 4000. The wind wheel 6200 may be a centrifugal wind wheel, and has a rotation axis, the transmission shaft 4000 is disposed at the rotation axis of the wind wheel 6200 and is fixedly connected with the wind wheel 6200, the transmission shaft 4000 and the wind wheel 6200 cannot rotate relatively, and the transmission shaft 4000 rotates with the length direction of the transmission shaft 4000 as the rotation axis under the driving of the motor 6100, so that the wind wheel 6200 can be driven to rotate synchronously.
When the transmission shaft 4000 and the motor 6100 are connected, which corresponds to that one end of the transmission shaft 4000 is fixed, the other end of the transmission shaft 4000 is penetrated with at least two wind wheels 6200, that is, the transmission shaft 4000 is cantilevered, so that the other end of the transmission shaft 4000 needs to be fixed, in this embodiment, the support of the transmission shaft 4000 is realized by setting the bracket 1000, it can be understood that in order to enable the transmission shaft 4000 to rotate stably, a bearing block 2000 and a bearing 3000 need to be configured, and the bearing block 2000 and the bearing 3000 are used together. The bearing 3000 is a component capable of supporting the transmission shaft 4000 to rotate and reducing the resistance to the rotation of the transmission shaft 4000, for example, the bearing 3000 includes an inner ring, an outer ring and balls between the inner ring and the outer ring, the transmission shaft 4000 passes through the bearing 3000, i.e. passes through the inner ring and is fixed with the inner ring, the rotation of the transmission shaft 4000 can drive the inner ring to rotate relative to the outer ring, and the outer ring is fixed to the bearing block 2000 and is fixed relative to the bearing block 2000. The bearing housing 2000 is a member for supporting the bearing 3000, ensuring stability of the bearing 3000 during rotation of the transmission shaft 4000, such as the outer race of the bearing 3000 being fixed into the bearing housing 2000. In order to conveniently combine the bearing housing 2000 with the bracket 1000, the bracket 1000 is provided with the cavity 1100 and the opening 1200, the opening 1200 is communicated with the cavity 1100, and the opening 1200 is arranged in the radial direction of the cavity 1100, it is understood that the radial direction is perpendicular to the axial direction of the cavity 1100, and when the transmission shaft 4000 is mounted to the bracket 1000, the axial direction of the cavity 1100 is the extending direction of the transmission shaft 4000, so that the bracket 1000 is formed with a non-closed arc structure by the arrangement of the cavity 1100 and the opening 1200. For example, taking the case that the bracket 1000 is vertically and fixedly installed to the indoor unit of an air conditioner as an example, the cavity 1100 forms an upwardly opened opening 1200, so that the bearing seat 2000 can be inserted into the cavity 1100 from top to bottom through the opening 1200, thus realizing the installation of the bracket 1000, and due to the existence of the opening 1200, the bearing seat 2000 enters the cavity 1100 from the opening 1200 to gradually approach to the wall of the cavity 1100 in the process of installing the bearing seat 2000, thus effectively improving the installation efficiency of the bearing seat 2000, and when the bearing seat 2000 is installed to the bracket 1000, the bearing seat 2000 is seated on the bracket 1000 under the action of gravity, thus forming preliminary positioning, and facilitating the subsequent fastening operation. If the cavity 1100 is not provided with the opening 1200, which forms the bracket 1000 into a closed ring shape, it is necessary to repeatedly align the bearing housing 2000 when the bearing housing 2000 is installed, reducing installation efficiency.
From the above, the technical scheme of the application is that the support 1000, the bearing seat 2000, the bearing 3000 and the transmission shaft 4000 are arranged, the bearing 3000 is arranged in the bearing seat 2000, the transmission shaft 4000 is penetrated by the bearing 3000, the support 1000 is provided with the containing cavity 1100 and the opening 1200 communicated with the containing cavity 1100, the bearing seat 2000 can be embedded into the containing cavity 1100 from the opening 1200 so as to be mounted on the support 1000, and the installation of the bearing seat 2000 is facilitated due to the existence of the opening 1200, so that the support of the transmission shaft 4000 is realized, and the mounting efficiency of the transmission shaft 4000 is greatly improved.
Referring to fig. 4 to 6, in some embodiments of the present application, the bearing housing 2000 includes an upper bearing housing 2200 and a lower bearing housing 2100, the upper bearing housing 2200 and the lower bearing housing 2100 are combined into the whole bearing housing 2000 by means of interconnection, and when the upper bearing housing 2200 and the lower bearing housing 2100 are connected with each other, a mounting cavity 2500 is formed, and the mounting cavity 2500 is used to mount the bearing 3000, so that the bearing 3000 is more conveniently mounted therein by designing the bearing housing 2000 as the upper bearing housing 2200 and the lower bearing housing 2100.
Specifically, since the bearing 3000 is required to prevent the bearing 3000 from coming out of the bearing housing 2000 after being mounted on the bearing housing 2000, when the bearing housing 2000 is designed as the upper bearing housing 2200 and the lower bearing housing 2100, the upper bearing housing 2200 and the lower bearing housing 2100 are abutted to cover the bearing 3000, so that the bearing 3000 can be limited and fixed, and the connection mode is simpler. There are various ways when mounting the bearing housing 2000 to the bracket 1000. For example, the lower bearing seat 2100 is first mounted on the bracket 1000, then the transmission shaft 4000 with the bearing 3000 mounted thereon is integrally moved toward the bracket 1000 until the bearing 3000 is supported on the lower bearing seat 2100, and then the upper bearing seat 2200 is fitted over the bearing 3000 and connected to the lower bearing seat 2100, so that the transmission shaft 4000 is supported and positioned. Alternatively, the bearing 3000 may be fixed to the driving shaft 4000, then the upper bearing housing 2200 and the lower bearing housing 2100 may be jointly coated with the bearing 3000 to be fixed, and then the driving shaft 4000, the bearing 3000 and the bearing housing 2000, which are combined as one body, may be moved toward the bracket 1000 until the bearing housing 2000 is installed by being integrally seated in the cavity 1100 through the opening 1200. Regardless of the manner, the mounting efficiency between the bearing housing 2000 and the bearing 3000 is improved by the combination of the upper bearing housing 2200 and the lower bearing housing 2100.
Alternatively, as shown in connection with fig. 4 to 6, in order to achieve the fastening between the bearing housing 2000 and the bracket 1000, the bearing housing 2000 is connected to the periphery of the opening 1200, i.e., a portion of the bracket 1000 near the opening 1200, which is located outside the cavity 1100, without interfering with the insertion of the bearing housing 2000 into the cavity 1100.
For example, after the bearing housing 2000 is mounted to the bracket 1000, in order to achieve the connection fastening between the bearing housing 2000 and the bracket 1000, the flange 2300 is respectively provided with the upper bearing housing 2200 and the lower bearing housing 2100, and the flange 2300 is abutted against the periphery of the opening 1200, so that the fastening between the bearing housing 2000 and the bracket 1000 can be conveniently achieved through the flange 2300 and the periphery of the opening 1200.
Specifically, when the bearing housing 2000 is mounted on the bracket 1000, the lower bearing housing 2100 is embedded in the cavity 1100, or all of the lower bearing housing 2100 is embedded in the cavity 1100, or part of the lower bearing housing 2100 is embedded in the cavity 1100, and flanges 2300 are provided at opposite ends of the lower bearing housing 2100, and the flanges 2300 of the lower bearing housing 2100 overlap around the opening 1200, that is, overlap around the portion of the bracket 1000 near the opening 1200. And as for the upper bearing housing 2200, the opposite ends of the upper bearing housing 2200 also have flanges 2300, when the upper bearing housing 2200 is connected with the lower bearing housing 2100, the flanges 2300 of the upper bearing housing 2200 are opposite to the flanges 2300 of the lower bearing housing 2100, so that the fastening between the bracket 1000 and the bearing housing 2000 can be achieved only by fastening the flanges 2300 of the upper bearing housing 2200, the flanges 2300 of the lower bearing housing 2100, and the periphery of the opening 1200, thereby achieving the positioning and supporting of the transmission shaft 4000. Because the flange 2300 of the upper bearing seat 2200 and the lower bearing seat 2100 conveniently deviate from the installation cavity 2500 to extend, the flange 2300 is connected, the installation of the bearing 3000 to the installation cavity 2500 is not influenced, and the flange 2300 is arranged, so that the bearing seat 2000 can play a certain supporting and positioning role when being seated on the bracket 1000, and the subsequent fastening operation is more convenient.
Alternatively, as shown in connection with fig. 5 and 6, in some embodiments of the present application, a secure connection between the bracket 1000 and the bearing mount 2000 is achieved by a fastener 8000. In this embodiment, the fastening member 8000 is a threaded fastening member, such as a bolt, a screw, or the like, and the flanges 2300 of the upper bearing housing 2200, the lower bearing housing 2100, and the periphery of the opening 1200 are respectively provided with mounting holes, and the fastening member 8000 sequentially penetrates the mounting holes of the respective components to fasten the respective components, so that the fastening connection between the bearing housing 2000 and the bracket 1000 is achieved. Because the fastener 8000 is penetrated with the flange 2300 of the upper bearing seat 2200 and the flange 2300 of the lower bearing seat 2100, the fastening of the bearing 3000 is realized between the upper bearing seat 2200 and the lower bearing seat 2100, the interference to the bearing 3000 can not be generated in the process of screwing the flange 2300, and the fixation among the bracket 1000, the bearing seat 2000, the bearing 3000 and the transmission shaft 4000 is conveniently realized.
As shown in fig. 3, 4 and 8, in some embodiments of the present application, the transmission shaft mounting structure further includes a bearing rubber ring 5000, where the bearing rubber ring 5000 has a certain elasticity, for example, the bearing rubber ring 5000 is made of rubber, so as to form a closed ring shape. Because the transmission shaft 4000 drives the wind wheel 6200 and rotates the in-process of certain vibrations can appear, in order to avoid vibrations to transmit to the support 1000 and arouse the noise, through setting up bearing rubber 5000, bearing rubber 5000 wholly is hollow annular structure, bearing 3000 places in bearing rubber 5000, bearing rubber 5000 encircles bearing 3000's circumference cladding bearing 3000 promptly, and bearing rubber 5000 then installs in bearing frame 2000, that is to say, set up bearing rubber 5000 between bearing 3000 and the bearing frame 2000, realize buffering through bearing rubber 5000, when vibrations are transmitted to bearing 3000 by transmission shaft 4000, bearing rubber 5000 can absorb the energy of vibrations, prevent to continue to transmit to bearing frame 2000 and then transmit to in the support 1000, thereby avoid the emergence of noise.
Optionally, in some embodiments of the present application, in order to further facilitate the fixing of the bearing rubber ring 5000 and prevent the bearing rubber ring 5000 from separating from the bearing seat 2000, a groove 2400 is provided on the bearing seat 2000, the groove 2400 extends around the inner side of the bearing seat 2000, so that the peripheral portion of the bearing rubber ring 5000 can be embedded into the groove 2400 to avoid separating from the bearing seat 2000 along the axial direction of the bearing seat 2000. Specifically, when the bearing housing 2000 includes the upper bearing housing 2200 and the lower bearing housing 2100, the upper bearing housing 2200 and the lower bearing housing 2100 have groove structures, respectively, and are butted with each other to form the completed groove 2400, thereby realizing the coated bearing rubber 5000.
