Description

Technical Field

[0001] This utility model relates to the field of sprocket mounting structure technology, and in particular to a sprocket positioning structure that is easy to adjust. Background Technology

[0002] The sprocket is an important component of the elevator. The sprocket supports the chain and drives the driven shaft to rotate under the transmission of the chain. It works in conjunction with the chain to complete tasks such as lifting the bucket.

[0003] In the prior art, in order to make the sprocket more stable during use, the sprocket is usually welded to the driven shaft. Although this positioning method can play a good role in fixing, the sprocket is bound to be damaged under long-term working environment. Therefore, the sprocket needs to be cleaned and maintained regularly. The welded sprocket cannot be directly removed, which is inconvenient for subsequent cleaning and maintenance work.

[0004] Therefore, this application provides an easily adjustable sprocket positioning structure to meet the requirements. Utility Model Content

[0005] The purpose of this application is to provide an easily adjustable sprocket positioning structure, which aims to solve the problem that in existing structures, it is inconvenient to remove the sprocket for cleaning and maintenance.

[0006] To achieve the above objectives, this application provides the following technical solution: an easily adjustable sprocket positioning structure, comprising a driven shaft, a sprocket, and positioning blocks. The driven shaft has two sets of mounting grooves, each containing a positioning block. The driven shaft is also fitted with the sprocket, which is mounted on the back face of the two sets of positioning blocks. By using separate positioning blocks, which cooperate with through grooves on the driven shaft, the positioning blocks and the driven shaft are engaged and limited. Multiple sets of through holes are provided on the positioning blocks, through which bolts are passed to connect with the sprocket, thereby limiting the movement between the sprocket and the driven shaft and completing the installation and fixing of the sprocket. The steps are simple and convenient, and also facilitate subsequent cleaning and maintenance of the sprocket.

[0007] Preferably, the positioning block has a through groove, and the positioning block is engaged with the driven shaft through the fitting relationship between the through groove and the mounting groove.

[0008] Preferably, the positioning block includes two halves, and the halves are provided in two sets with the same structure.

[0009] Preferably, the positioning block is connected to the sprocket by bolts, and the positioning block is also provided with through holes for the bolts to pass through.

[0010] Preferably, the through holes are provided in four groups and arranged in a circular array around the center of the positioning block.

[0011] In summary, the technical effects and advantages of this utility model are as follows:

[0012] In this utility model, a split positioning block is used in conjunction with a through groove on the driven shaft to lock and limit the positioning block and the driven shaft. Multiple through holes are opened on the positioning block, and bolts are used to pass through the through holes to connect with the sprocket, thereby limiting the sprocket and the driven shaft and completing the installation and fixing of the sprocket. The steps are simple and convenient, and it is also convenient for subsequent cleaning and maintenance of the sprocket. Attached Figure Description

[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] Example 1: Reference Figure 1-4The sprocket positioning structure shown includes a driven shaft 1, a sprocket 2, and a positioning block 3. The driven shaft 1 has a mounting groove 4, which has two sets. The positioning block 3 is installed in both sets of the mounting groove 4. The positioning block 3 includes a half block 31, and there are two sets of half blocks 31 with the same structure.

[0022] The positioning block 3 has a through groove 32, and the positioning block 3 is engaged with the driven shaft 1 through the matching relationship between the through groove 32 and the mounting groove 4.

[0023] The driven shaft 1 is also fitted with the sprocket 2, which is mounted on the back surface of the two sets of positioning blocks 3.

[0024] The positioning block 3 is connected to the sprocket 2 by bolts, and the positioning block 3 is also provided with through holes 33 for the bolts to pass through. There are four sets of through holes 33, which are arranged in a circular array around the center of the positioning block 3.

[0025] The working principle of this utility model is as follows: During installation, the through grooves 32 on the two sets of half blocks 31 are aligned with the through grooves 32 on the driven shaft 1 and snapped together. After snapping, the sprocket 2 is mounted on the driven shaft 1, and the threaded hole on the sprocket 2 is aligned with the through hole 33 on the positioning block 3.
