Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of shaft support brackets, and specifically relates to a chain-driven shaft support bracket. Background Technology
[0002] Traditional shaft support fixtures use U-shaped or V-shaped structures with relatively simple pin contact surface structures. The pin moves by sliding or using rollers on the support surface, which is only suitable for cylindrical pins. For pins with bosses, it is difficult to ensure the pin is horizontal, and the pin movement is extremely inconvenient. Utility Model Content
[0003] In order to solve the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a chain-driven shaft support bracket. The chain-driven shaft support fixture can adapt very well to cylindrical and bossed pins, and the movement of the pins is more convenient.
[0004] The technical solution adopted in this utility model is as follows:
[0005] A chain-driven shaft support bracket includes a support with a V-shaped cross-section. Both sides of the support are equipped with sprocket and chain assemblies. Each sprocket and chain assembly includes a drive sprocket and an idler sprocket, both mounted on the support. A chain assembly drives the drive sprocket and the idler sprocket, and several support blocks are spaced apart on the chain assembly. When supporting a pin with a boss, the boss is placed in the gap between adjacent support blocks, and the support blocks support the working surface of the pin.
[0006] When the drive sprocket rotates, it drives the chain assembly to move. The chain assembly then drives the idler sprocket to rotate. The drive sprocket and the idler sprocket provide stable support for the chain assembly. The pin is placed between the sprocket and chain assemblies on both sides and is supported by support blocks. When the chain assembly moves stably with the support blocks, the pin can move smoothly.
[0007] The bracket of this invention has a V-shaped cross-section, and sprocket and chain assemblies are symmetrically arranged on both sides of the bracket to facilitate the forward and backward movement of the pin. The pin is supported by spaced-apart support blocks, and the boss can be placed in the gap between adjacent support blocks. Therefore, this invention can not only accommodate cylindrical pins, but also support pins with bosses.
[0008] As a preferred embodiment of this utility model, the sprocket and chain assembly further includes a drive sprocket shaft and an idler sprocket shaft. Both the drive sprocket shaft and the idler sprocket shaft are rotatably connected to the bracket. Two drive sprockets are installed on the drive sprocket shaft, and two idler sprockets are installed on the idler sprocket shaft. A chain group is connected between the drive sprockets and idler sprockets on the same side. The support block is connected between the two chain groups.
[0009] When the drive sprocket shaft rotates, it drives the two drive sprockets on it to rotate synchronously. The two drive sprockets drive the two chain assemblies to move, and the two chain assemblies drive the two idler sprockets to rotate. Through the movement of the two chain assemblies, the support block between the two chain assemblies moves smoothly.
[0010] As a preferred embodiment of this utility model, both ends of the drive sprocket shaft are connected to the bracket with bracket rolling bearings. The use of bracket rolling bearings to mount the drive sprocket to the bracket ensures the flexibility of the chain assembly's rotation.
[0011] As a preferred embodiment of this utility model, a flat key is provided between the drive sprocket shaft and the drive sprocket. The drive sprocket of each sprocket and chain assembly is mounted on the drive sprocket shaft via a flat key, ensuring the synchronization of the sprocket and chain assembly transmission.
[0012] As a preferred embodiment of this utility model, both ends of the drive sprocket shaft extending from the bracket are connected to drive sprocket shaft retaining rings. The drive sprocket shaft retaining rings limit the drive sprocket shaft, preventing it from dislodging from the bracket.
[0013] As a preferred embodiment of this utility model, both ends of the inertial sprocket shaft are connected to the bracket with inertial sprocket rolling bearings. The inertial sprocket and the bracket are installed using inertial sprocket rolling bearings, ensuring the flexibility of the chain assembly's rotation.
[0014] As a preferred embodiment of this utility model, both ends of the inertial sprocket shaft extending from the bracket are connected to inertial sprocket shaft retaining rings. The inertial sprocket shaft retaining rings limit the inertial sprocket shaft and prevent it from coming off the bracket.
[0015] In a preferred embodiment of this invention, the support block is connected to the chain assembly by screws.
[0016] As a preferred embodiment of this utility model, the chain assembly is provided with a single-sided chain bend plate.
[0017] As a preferred embodiment of this utility model, the support block is connected to a single-sided chain bend plate.
[0018] The beneficial effects of this utility model are as follows:
[0019] The bracket of this invention has a V-shaped cross-section, and sprocket and chain assemblies are symmetrically arranged on both sides of the bracket to facilitate the forward and backward movement of the pin. The pin is supported by spaced-apart support blocks, and the boss can be placed in the gap between adjacent support blocks. Therefore, this invention can not only accommodate cylindrical pins, but also support pins with bosses. Attached Figure Description

Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other.
[0027] like Figures 1-4 As shown, the chain-driven shaft support bracket of this embodiment includes a bracket 1 with a V-shaped cross-section. Both sides of the bracket 1 are equipped with sprocket and chain assemblies 2. Each sprocket and chain assembly 2 includes a drive sprocket 21 and an idler sprocket 22, both mounted on the bracket 1. A chain assembly 23 connects the drive sprocket 21 and the idler sprocket 22, with several support blocks 3 spaced apart on the chain assembly 23. When a pin 4 with a boss 41 is supported, the boss 41 is placed in the gap between adjacent support blocks 3, and the support blocks 3 support the working surface of the pin 4. The sprocket and chain assemblies 2 are symmetrically mounted on the bracket 1, forming a V-shaped transmission structure.
[0028] When the drive sprocket 21 rotates, it drives the chain assembly 23 to move. The chain assembly 23 drives the idler sprocket 22 to rotate. The drive sprocket 21 and the idler sprocket 22 provide stable support for the chain assembly 23. The pin 4 is placed between the sprocket and chain assemblies 2 on both sides and is supported by the support block 3. When the chain assembly 23 drives the support block 3 to move stably, the pin 4 can move smoothly.
[0029] The bracket 1 of this invention has a V-shaped cross-section, and sprocket and chain assemblies 2 are symmetrically arranged on both sides of the bracket 1 to facilitate the forward and backward movement of the pin 4. The pin 4 is supported by spaced-apart support blocks 3, and the boss 41 can be placed in the gap between adjacent support blocks 3. Thus, this invention can not only accommodate cylindrical pins 4, but also support pins 4 with bosses 41.
[0030] Specifically, the sprocket and chain assembly 2 further includes a drive sprocket shaft 24 and an idler sprocket shaft 25. Both the drive sprocket shaft 24 and the idler sprocket shaft 25 are rotatably connected to the bracket 1. Two drive sprockets 21 are installed on the drive sprocket shaft 24, and two idler sprockets 22 are installed on the idler sprocket shaft 25. A chain group 23 is connected between the drive sprockets 21 and the idler sprockets 22 on the same side. The support block 3 is connected between the two chain groups 23.
[0031] When the drive sprocket shaft 24 rotates, it drives the two drive sprockets 21 on it to rotate synchronously. The two drive sprockets 21 drive the two chain groups 23 to move, and the two chain groups 23 drive the two idler sprockets 22 to rotate. Through the movement of the two chain groups 23, the support block 3 between the two chain groups 23 moves smoothly.
[0032] Furthermore, each end of the drive sprocket shaft 24 is connected to a bracket rolling shaft 26 between itself and the bracket 1. The drive sprocket 21 is mounted to the bracket 1 using a bracket rolling bearing 26, ensuring the flexibility of the chain assembly 23 in rotation.
[0033] A key 241 is provided between the drive sprocket shaft 24 and the drive sprocket 21. The drive sprocket 21 of each sprocket and chain assembly 2 is mounted on the drive sprocket shaft 24 via the key 241, ensuring the synchronization of the transmission of the sprocket and chain assembly 2.
[0034] Both ends of the drive sprocket shaft 24 extending out of the bracket 1 are connected to drive sprocket shaft retaining rings 27. The drive sprocket shaft retaining rings 27 limit the drive sprocket shaft 24 to prevent it from coming off the bracket 1.
[0035] Furthermore, both ends of the inertial sprocket shaft 25 are connected to the bracket 1 by inertial sprocket rolling bearings 28. The inertial sprocket 22 is installed with the bracket 1 using inertial sprocket rolling bearings 28, ensuring the flexibility of the chain assembly 23 in rotation.
[0036] Both ends of the inertial sprocket shaft 25 extending out of the bracket 1 are connected to inertial sprocket shaft retaining rings 29. The inertial sprocket shaft retaining rings 29 limit the inertial sprocket shaft 25 to prevent it from coming off the bracket 1.
[0037] The support block 3 is connected to the chain assembly 23 by screws.
[0038] The chain assembly 23 is provided with a single-sided chain bend plate 231.
[0039] The support block 3 is connected to the single-sided chain bending plate 231.
[0040] Working principle:
[0041] Two sets of sprocket and chain assemblies 2 are symmetrically mounted on a V-shaped bracket 1. Each set of sprocket and chain assembly 2 includes two chain groups 23 and spaced-apart support blocks 3. The drive sprocket 21 is mounted on the drive sprocket shaft 24 via a flat key 241 to ensure the synchronization of the two chain groups 23 in this set of sprocket and chain assembly 2. The drive sprocket shaft 24 is mounted to the bracket 1 via a bracket rolling bearing 26, and the idler sprocket 22 is mounted to the idler sprocket shaft 25 via an idler sprocket rolling bearing 28. The configuration of the rolling bearings greatly improves the flexibility of the sprocket and chain assembly 2.
[0042] For the cylindrical pin 4, the pin 4 can be freely supported on the support blocks 3 on both sides of the V-shaped bracket 1. When the pin 4 needs to move, the sprocket and chain assemblies 2 on both sides can transport the pin 4 to move.
[0043] For a pin 4 with a boss 41, when supporting the pin 4, the boss 41 can be placed in the gap between adjacent support blocks 3, and the support blocks 3 support the working surface of the pin 4 to ensure the pin 4 is horizontal. When the pin 4 needs to move, the sprocket and chain assemblies 2 on both sides can transport the pin 4 to move, which greatly solves the problem of the pin 4 being horizontal and moving.
[0044] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
