Description

Technical Field

[0001] The utility model relates to the technical field of glass homogenizing furnaces, and particularly to a hanging type easily disengaging transmission coupling device. Background Technique

[0002] With the improvement of domestic requirements for building safety, the demand for large-scale building glass homogenization treatment has become increasingly urgent. To meet this demand, various large-scale tempered glass homogenizing furnaces have been developed in the industry.

[0003] A rotating part and a shaft for driving the rotating part to rotate are arranged in the glass tempering and homogenizing furnace. The rotating part plays a role in separating or communicating the inner cavity of the furnace body. Due to the complex structure and compact installation space of the large-scale tempered glass homogenizing furnace, and the relatively large external dimension of the rotating part, the installation space is often limited, making it inconvenient to fix the shaft and the rotating part by traditional methods such as bolts, and it is also inconvenient for installation and disassembly.

[0004] Therefore, we have studied and proposed a hanging type easily disengaging transmission coupling device. Content of the Utility Model

[0005] The purpose of the utility model is to propose a hanging type easily disengaging transmission coupling device, in which the rotating part is not limited by the installation space in the furnace body during installation, can maintain stability during operation, and is convenient for quick installation and disassembly.

[0006] The technical solution adopted by the utility model is: a hanging type easily disengaging transmission coupling device, including a rotating part arranged in the furnace body, which divides the inner cavity of the furnace body into adjacent chambers. An adjusting ring coinciding with its center line is arranged at the top of the rotating part, and a clamping groove is arranged on the inner ring surface of the adjusting ring;

[0007] A rotatable hanging shaft is suspended in a vertically arranged hanging hole at the top of the furnace body. A shaft key is arranged at the lower end of the hanging shaft. After the lower end of the hanging shaft is inserted into the adjusting ring, the shaft key can be clamped with the clamping groove, and when the shaft key is clamped and matched with the clamping groove, the rotating part is suspended in the inner cavity of the furnace body.

[0008] As a preferred solution, the clamping groove includes a guiding groove, a transmission key groove, and a rotating sliding groove connecting the guiding groove and the transmission key groove;

[0009] The guiding groove penetrates through the upper end surface of the adjusting ring and extends downward;

[0010] The rotating sliding groove is connected to the lower end of the guiding groove and extends along the circumferential direction of the adjusting ring;

[0011] The transmission key groove is connected to the end of the rotating sliding groove and has a blocking wall for restricting the circumferential rotation and axial upward movement of the shaft key.

[0012] As a preferred solution, there are two shaft keys and they are arranged oppositely on the circumferential surface of the lower end of the hanging shaft;

[0013] There are two guiding grooves and transmission key grooves, which are oppositely arranged on the inner ring surface of the adjusting ring.

[0014] As a preferred solution, the lower end of the rotating part is connected to the bottom surface of the inner cavity of the furnace body through a connecting part for restricting the swing of the lower end of the rotating part.

[0015] As a preferred solution, the connecting part includes a positioning sleeve fixed on the bottom surface of the inner cavity of the furnace body and a positioning shaft fixed on the rotating part and coinciding with its center line. The positioning shaft extends downward into the central hole of the positioning sleeve.

[0016] As a preferred solution, a bearing seat assembly for installing the hanging shaft is provided in the hanging hole.

[0017] As a preferred solution, the bearing seat assembly includes a bearing seat, a shaft sleeve, a bearing and a gland;

[0018] The bearing seat is installed in the hanging hole. A shaft sleeve and bearings at both ends of the shaft sleeve are arranged in the inner cavity of the bearing seat. The upper end of the hanging shaft passes through the shaft sleeve and the bearings, and the upper end of the bearing seat is closed by the gland.

[0019] As a preferred solution, the upper end of the hanging shaft is connected to a driving mechanism outside the furnace body for suspending the hanging shaft to a certain height and driving the hanging shaft to rotate along its own axis.

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0021] 1. Insert the hanging shaft from the top of the furnace body downward, which can be directly clamped with the adjusting ring, realizing the suspension installation of the rotating part. No other limiting structures are required, solving the problem of insufficient installation space and reducing the installation difficulty at the same time.

[0022] 2. When the shaft key of the hanging shaft is clamped with the card slot of the adjusting ring, it can restrict the circumferential rotation and axial upward movement of the hanging shaft, so as to keep the rotating part suspended through a separable hanging shaft and transmit torque to the rotating part at the same time.

[0032] For a clearer description of the specific structural composition of the hanging type easily disengaged transmission coupling device, in combination with the attached Figures 1-4 Describe this embodiment:

[0033] As Figure 1 , Figure 2 and Figure 3As shown in the figure, a hanging type easily detachable transmission coupling device. The rotating member 2 divides the inner cavity of the furnace body 1 into adjacent chambers. At the top of the rotating member 2, there is an adjustment ring 3 coinciding with its center line. The inner ring surface of the adjustment ring 3 has a card slot 4. A rotatable hanging shaft 6 is suspended in the vertical hanging hole 5 at the top of the furnace body 1. At the lower end of the hanging shaft 6, there is a shaft key 7. After the lower end of the hanging shaft 6 is inserted into the adjustment ring 3, the shaft key 7 can be engaged with the card slot 4. When the shaft key 7 is engaged with the card slot 4, the rotating member 2 is suspended in the inner cavity of the furnace body 1. Passing the hanging shaft 6 through the top of the furnace body 1 downward can be directly engaged with the adjustment ring 3 without other limiting structures, solving the problem of insufficient installation space and reducing the installation difficulty at the same time. When the shaft key 7 of the hanging shaft 6 and the card slot 4 of the adjustment ring 3 are engaged, it can limit the circumferential rotation and axial upward movement of the hanging shaft 6, so that the rotating member 2 is kept suspended by a separable hanging shaft 6 and at the same time transmit torque to the rotating member 2.

[0034] Refer to Figure 4 , in the above embodiment, the card slot 4 includes a guiding slot 401, a transmission key slot 403, and a rotating sliding slot 402 communicating the guiding slot 401 and the transmission key slot 403. The guiding slot 401 penetrates the upper end surface of the adjustment ring 3 and extends downward. The rotating sliding slot 402 is connected to the lower end of the guiding slot 401 and extends along the circumferential direction of the adjustment ring 3. The transmission key slot 403 is connected to the extending end of the rotating sliding slot 402 and has a blocking wall for restricting the circumferential rotation and axial upward movement of the shaft key 7. After the lower end of the hanging shaft 6 is inserted into the adjustment ring 3, by adjusting the relative positions of the shaft key 7 and the card slot 4, the hanging shaft 6 and the adjustment ring 3 can be engaged, so that torque can be transmitted to the rotating member 2 through the hanging shaft 6 and the adjustment ring 3. The outer dimensions of the guiding slot 401, the rotating sliding slot 402, the transmission key slot 403 and the shaft key 7 are adapted to ensure that they can move in the slots. Specifically in the design, the guiding slot 401 can be arranged along the axial direction of the adjustment ring 3, the shape of the transmission key slot 403 and the shaft key 7 can be kept the same, and the rotating sliding slot 402 can be arranged along the axial direction of the adjustment ring 3. During use, a temporary auxiliary tooling is used to support the rotating member 2. While keeping it vertical, the hanging hole 5 and the adjustment ring 3 are vertically corresponding. The hanging shaft 6 passes through the hanging hole 5 from top to bottom and then is inserted into the inner cavity of the adjustment ring 3. During this process, the shaft key 7 slides downward along the guiding slot 401 until it reaches the position where the guiding slot 401 and the rotating sliding slot 402 intersect. Then the hanging shaft 6 is rotated circumferentially to make the shaft key 7 move along the rotating sliding slot 402 until it reaches the position corresponding to the rotating sliding slot 402 and the transmission key slot 403. The hanging shaft 6 is lifted upward to make the shaft key 7 snap into the transmission key slot 403, completing the assembly of the hanging shaft 6.

[0035] During the installation of the hanging shaft 6 in the above embodiments, since the angle of the rotating member 2 is fixed, only the angle of the hanging shaft 6 needs to be adjusted. To facilitate determining the position of the shaft key 7, a marking line can be set at the upper end of the hanging shaft 6 corresponding to the shaft key 7. In this way, the angle of the hanging shaft 6 can be judged only from the outside of the furnace body 1, which is beneficial to the cooperation between the shaft key 7 and the card slot 4.

[0036] At least one of the shaft key 7 and the transmission key slot 403 can also be set in pairs. There are two shaft keys 7 which are oppositely arranged on the circumferential surface of the lower end of the hanging shaft 6. Correspondingly, there are two guiding slots 401 and transmission key slots 403 which are oppositely arranged on the inner ring surface of the adjusting ring 3.

[0037] Refer to Figure 2 , when there is a slight surplus in the inner cavity of the furnace body, the lower end of the rotating member 2 is connected to the bottom surface of the inner cavity of the furnace body 1 through a connecting member for restricting the swing of the lower end of the rotating member 2, reducing the swing that may be caused by the suspension of the lower end of the rotating member during rotation and improving stability. Specifically, the connecting member includes a positioning sleeve 8 fixed on the bottom surface of the inner cavity of the furnace body 1 and a positioning shaft 9 fixed on the rotating member 2 and coinciding with its center line. The positioning shaft 9 extends downward into the central hole of the positioning sleeve 8. The positioning sleeve 8 does not need to provide support for the rotating member 2, and only needs to ensure that the positioning shaft 9 does not come off.

[0038] Refer to Figure 2 , during specific installation, a bearing seat assembly for installing the hanging shaft 6 is provided in the hanging hole 5. The bearing seat assembly includes a bearing seat 10, a shaft sleeve 11, a bearing 12 and a gland 13; the bearing seat 10 is installed in the hanging hole 5, the inner cavity of the bearing seat 10 is provided with a shaft sleeve 11 and bearings 12 at both ends of the shaft sleeve 11, the upper end of the hanging shaft 6 passes through the shaft sleeve 11 and the bearing 12, and the upper end of the bearing seat 10 is closed by the gland 13. After the hanging shaft 6 is installed in place, the bearing seat 10 is installed in the hanging hole 5, the bearing 12 and the shaft sleeve 11 are sequentially installed on the hanging shaft 6 and fixed with the gland 13, and the hanging shaft 6 is adjusted to a preset height to ensure that the gap between the rotating member 2 and the bottom surface of the inner cavity of the furnace body 1 meets the process requirements.

[0039] The upper end of the hanging shaft 6 is connected to a driving mechanism outside the furnace body for suspending the hanging shaft 6 to a certain height and driving the hanging shaft 6 to rotate along its own axis. The driving mechanism drives the hanging shaft 6 and the rotating member 2 to rotate to realize the connection or blockage of adjacent chambers in the furnace body. The driving mechanism is selected and arranged according to actual needs and is not shown in the illustration. After the whole assembly is completed, the temporary auxiliary tooling for supporting the rotating member 2 is removed.

[0040] The parts not detailed in this embodiment are prior art.

[0041] It should be noted that although the present utility model has been described through the above embodiments, the present utility model can also have many other embodiments. Without departing from the spirit and scope of the present utility model, those skilled in the art can obviously make various corresponding changes and deformations to the present utility model, but these changes and deformations should all fall within the scope protected by the appended claims of the present utility model and their equivalents.
