Description

Technical Field

[0001] This utility model relates to the field of tooling technology, specifically a gear disassembly tooling for screw fans. Background Technology

[0002] Gears used in screw blowers are rotating components used to transmit power and control the internal rotation of the blower. Screw blowers generally adopt the screw working principle, and gears play the role of connecting and transmitting power in this process. In the drive system of the blower, gears usually transmit power through meshing with the motor, internal gears and external gears.

[0003] Because gears experience wear and fatigue during long-term operation, they need to be disassembled regularly for inspection to prevent malfunctions. Workers usually use hydraulic pullers to disassemble gears, but the internal space of a screw blower is limited, and the gears are close to the blower casing. Hydraulic pullers usually require a certain amount of operating space to apply force, so the clamping and disassembly operations of the hydraulic puller are limited by space, making the disassembly process difficult. Therefore, we propose a gear disassembly fixture for screw blowers. Utility Model Content

[0004] The purpose of this utility model is to provide a gear disassembly fixture for screw fans, so as to solve the problem mentioned in the background art that the internal space of screw fans is limited, and the clamping and disassembly operations of hydraulic pullers are restricted by space, resulting in difficulties in the disassembly process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gear disassembly fixture for a screw fan, comprising a fan housing and a gear body. The gear body is installed on the inner side of the fan housing, and a support rod is provided on the outer side of the gear body. The outer side of the support rod is sequentially connected to a support plate one and a support plate two. A connecting pad one is adhered to one side of the support plate two. A threaded groove is opened inside the support plate one, and one side of the support plate one is fixed to one end of a hook. A connecting plate is provided on the side of the threaded groove away from the support plate two.

[0006] Preferably, a bolt runs through the interior of the connecting plate, and one end of the bolt is engaged with a threaded groove.

[0007] Preferably, one side of each of the three connecting plates is fixed to the outer side of the ring plate, and the support rod has a sliding groove inside.

[0008] Preferably, the groove is slidably connected to the connecting rod, and a screw body is inserted into one side of the connecting rod.

[0009] Preferably, the screw body is movably connected to the support rod via a bearing, and the end of the connecting rod away from the support rod is fixed to the support plate in three phases.

[0010] Preferably, a connecting pad two is bonded to one side of the support plate three, and the connecting pad two is made of deformable wear-resistant rubber material.

[0011] Preferably, the connecting pad is made of deformable wear-resistant rubber material, and the threaded groove is threadedly connected to the bolt.

[0012] Preferably, the inner spacing of the through groove of the connecting plate is greater than the diameter of the bolt, and the sliding groove matches the connecting rod.

[0013] Preferably, the connecting rod has a rectangular cross-section and is threaded to the screw body.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The screw blower uses a gear disassembly fixture to rotate the screw body, causing the support plate three to press against the blower housing, while the support plate two presses against the gear body. Then, the ring plate is restricted to the outside of the support plate one. At this time, the remaining support rods and support plate three are sequentially restricted together with the gear body and connecting plate. The puller claw of the hydraulic puller is connected to the hook. The puller claw of the hydraulic puller can pull the disassembly fixture through the hook, causing the disassembly fixture to drive the gear body away from the installation shaft of the blower housing, making the hydraulic puller less restricted by the space of the screw blower housing.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model provides a technical solution: a gear disassembly fixture for a screw fan, including a fan housing 1 and a gear body 101. The gear body 101 is installed on the inner side of the fan housing 1, and a support rod 2 is provided on the outer side of the gear body 101. The outer side of the support rod 2 is connected to a first support plate 201 and a second support plate 202 in sequence. A connecting pad 203 is glued to one side of the second support plate 202. A threaded groove 204 is opened inside the first support plate 201, and one side of the first support plate 201 is fixed to one end of a hook 205. A connecting plate 206 is provided on the side of the threaded groove 204 away from the second support plate 202. A bolt 207 passes through the inside of the connecting plate 206, and one end of the bolt 207 is connected to the threaded groove 204. One side of the three connecting plates 206 is connected to the outer side of a ring plate 208 in sequence. The support rod 2 is fixed, and a sliding groove 209 is provided inside the support rod 2. The sliding groove 209 slides and connects with the connecting rod 210. A screw body 211 is inserted into one side of the connecting rod 210. The screw body 211 is movably connected to the support rod 2 through a bearing. The end of the connecting rod 210 away from the support rod 2 is fixed to the support plate 3 212. A connecting pad 213 is bonded to one side of the support plate 3 212. The connecting pad 213 is made of deformable wear-resistant rubber material. The connecting pad 1 203 is made of deformable wear-resistant rubber material. The threaded groove 204 is threadedly connected to the bolt 207. The inner spacing of the through groove of the connecting plate 206 is greater than the diameter of the bolt 207. The sliding groove 209 matches the connecting rod 210. The cross-sectional dimension of the connecting rod 210 is rectangular, and the connecting rod 210 is threadedly connected to the screw body 211.

[0022] In specific implementation, according to Figures 1-4When the screw blower needs to replace the gear body 101, the blower housing 1 of the screw blower is disassembled. Then, one set of support plates 202 and 212 are placed on the side of the gear body 101 closest to the blower housing 1, so that support plates 202 and 212 are fitted together on one side of the gear body 101, and support plate 201 is placed on the other side of the gear body 101. At this time, the operator holds support plate 201 and uses a Torx screwdriver to rotate the screw body 211, causing the screw body 211 to rotate and match the connecting rod 210 through the sliding groove 209. The connecting rod 210 has a rectangular cross-section, ensuring that the connecting rod 210 does not follow the screw body 201. 11 rotates, and then the connecting rod 210 is threadedly connected to the screw body 211, allowing the connecting rod 210 to slide stably along the slide groove 209. This causes the connecting rod 210 to move the support plate 212, bringing it closer to the fan housing 1 for compression. The connecting pad 213, made of deformable wear-resistant rubber, strengthens the compression limit between the support plate 212 and the fan housing 1. Simultaneously, the support plate 202 and the gear body 101 are compressed on the side close to the fan housing 1. The connecting pad 203, also made of deformable wear-resistant rubber, further strengthens the compression limit between the support plate 202 and the gear body 101. At this time, the support rod 2 and... Support plate 3 212 is bound together with gear body 101. Connecting plate 206 is then attached to support plate 1 201. Bolt 207 is used to rotate and mate with threaded groove 204 through connecting plate 206. The threaded groove 204 and bolt 207 are threadedly connected, binding bolt 207 to support plate 1 201. Ring plate 208 is then bound to the outside of support plate 1 201. The remaining support rod 2 and support plate 3 212 are then bound together with gear body 101. Bolt 207 is then used to bind the remaining support plate 1 201 to connecting plate 206. At this point, all components of the disassembly fixture can be bound together with gear body 101. The operator can connect the hydraulic puller's puller claws to the hook 205, and the hydraulic puller's pin can pass through the ring plate 208 and fit against the mounting shaft of the fan housing 1. Activating the hydraulic puller causes the pin to press against the mounting shaft of the fan housing 1, causing the hydraulic puller's puller claws to pull outwards through the hook 205 to disassemble the tooling. At this time, the disassembly tooling is confined to the gear body 101, allowing the disassembly tooling to drive the gear body 101 away from the mounting shaft of the fan housing 1. By confining the disassembly tooling to the gear body 101, the hydraulic puller is less restricted by the space of the screw fan housing, making it convenient for the operator to use the hydraulic puller to disassemble the gear body 101.

[0023] In summary, by placing one set of support plates 202 and 212 on the side of the gear body 101 near the fan housing 1, rotating the screw body 211, and pressing the support plate 212 against the fan housing 1, while simultaneously pressing the support plate 202 against one side of the gear body 101, and then restricting the ring plate 208 to the outside of the support plate 201, the remaining support rod 2 and support plate 212 are then sequentially restricted together with the gear body 101 and the connecting plate 206. The hydraulic puller's puller claw is then connected to the hook 205, and the hydraulic puller is activated. This allows the hydraulic puller's puller claw to pull the disassembly fixture through the hook 205, causing the disassembly fixture to detach the gear body 101 from the mounting shaft of the fan housing 1. This makes the hydraulic puller less restricted by the space of the screw fan housing, facilitating the use of the hydraulic puller to disassemble the gear body 101. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0024] Although the present invention 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
