Of course, they are merely examples, and the purpose is not to limit the utility model.

In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0031] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0032] Example:

[0033] See also Figure 1 and Figure 2 A connection structure of a head gear piece includes a shaft connector 1, a semicircular tooth 2 and a connection plate 3. Specifically, the shaft connector 1 is installed on a hoist shaft 4, and the outer contour size of the shaft connector 1 is larger than the shaft diameter of the hoist shaft 4.

[0034] The shaft connector 1 is a polygonal columnar structure, and the length direction of the shaft connector 1 is consistent with the axial direction of the hoist shaft 4. Generally, the cross section of the shaft connector 1 is a regular polygon.

[0035] There are two semicircular teeth 2, and the two semicircular teeth 2 can be spliced ​​into a complete spur gear. The middle of the complete spur gear has a connecting channel 5, and the connecting channel 5 is a polygonal columnar space, and the connecting channel 5 can be matched with the shaft connector 1, so that the two semicircular teeth 2 are stuck on the shaft connector 1 from both sides of the shaft connector 1.

[0036] The connecting plate 3 is detachably arranged on both sides of the complete spur gear, the middle of the connecting plate 3 has a hole for the hoist shaft 4 to pass through, and the middle of the connecting plate also abuts against the end of the shaft connector 1 .

[0037] Preferably, the number of teeth of the complete spur gear formed by the two semicircular teeth 2 is an even number, and the connecting surface of the two semicircular teeth 2 is located at the tooth top of the complete spur gear.

[0038] The working principle of this embodiment is to first install the shaft connector 1 on the hoist shaft, and then form a complete spur gear by connecting two semi-circular teeth 2 to the shaft connector 1, and connect the two semi-circular teeth 2 into a whole through the connecting plate 3, so that the complete spur gear can function as a gear.

[0039] Since the cross section of the shaft connector 1 is a polygonal structure, and the connecting channel 5 in the middle of the complete spur gear can completely match the outside of the shaft connector 1, the complete spur gear can completely drive the shaft connector 1 and the shaft of the hoist to rotate together.

[0040] In the present technical solution, the installation process is to clamp the two semicircular teeth 2 on the shaft connection. The overall structure is simple and the installation is convenient. At the same time, there is no need to heat the two semicircular teeth 2 during installation, so the service life of the complete spur gear can be avoided from being reduced.

[0041] In one specific embodiment:

[0042] Two connecting plates 3 are symmetrically arranged on both side surfaces of the complete spur gear, wherein the connecting plates 3 have through holes 6, and the semicircular teeth 2 have connecting holes 7 running through both sides thereof, and the number of through holes 6 on the connecting plates 3 is half the size of the connecting holes 7 on the semicircular teeth 2.

[0043] A plurality of bolts (not shown in the figure) are arranged between the connecting plate 3 and the semicircular teeth 2, and the connecting plate 3 is fixed on the two semicircular teeth 2 by the bolts, so that the two semicircular teeth 2 are linked into a complete spur gear through the connecting plate 3.

[0044] In addition, two connecting plates 3 are provided so that the middle parts of the two connecting plates 3 are respectively abutted against the two ends of the shaft connector 1 , thereby positioning the position of the complete spur gear on the shaft connector 1 .

[0045] In another specific embodiment:

[0046] The length of the shaft connector 1 is greater than the thickness of the semicircular teeth 2 , and the middle portion of the connecting disk 3 has a structure protruding away from the semicircular teeth 2 , and the protruding structure is wrapped around the end of the shaft connector 1 .

[0047] By providing a protruding structure in the middle of the connecting disk 3 , a concave polygonal space can be formed in the middle of the connecting disk 3 , thereby assisting the positioning of the semicircular teeth 2 .

[0048] In another specific embodiment:

[0049] See also Figure 1-Figure 3 A connecting block 8 is also provided on the semicircular tooth 2. The cross section of the connecting block 8 is L-shaped. The connecting block 8 is provided on one side surface of the semicircular tooth 2 and forms a U-shaped structure with the side surface of the semicircular tooth 2.

[0050] A connecting block 8 is provided on both sides of the connecting passage 5 on the semicircular tooth 2 , and two connecting blocks 8 are provided on both side surfaces of the semicircular tooth 2 .

[0051] When the two semicircular teeth 2 are butted together to form a complete spur gear, the connecting blocks 8 on the two semicircular teeth 2 are spliced ​​to form a T-shaped connecting body. Two connecting bodies are respectively provided on both side surfaces of the complete spur gear.

[0052] Two limiting bodies 9 are arranged on each connector. The limiting bodies 9 are U-shaped structures. The two limiting bodies 9 are arranged at both ends of the connector respectively, and the movement of the limiting bodies 9 is limited by the end of the connector with a larger end surface area.

[0053] In the present technical solution, the two connection blocks 8 are locked by setting a limiting body 9 , thereby assisting the connection disk 3 to lock the two semicircular teeth 2 .

[0054] Preferably, the opening direction of the limiting body 9 is consistent with one of the radial directions of the semicircular teeth 2, so as to reduce the influence of the centrifugal force on the limiting body 9.

[0055] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
