Description

Technical Field

[0001] The utility model relates to the field of gear equipment, in particular to an adjustable synchronous wheel. Background Art

[0002] In the field of mechanical technology, the mutual engagement between synchronous wheels and synchronous belts is a common component to achieve linkage between different functional mechanisms. At present, the synchronous wheels on the market are mostly made of aluminum alloy, and the synchronous belts are mostly made of polyurethane. In comparison, the material of the aluminum alloy synchronous wheel is harder than the synchronous belt. Therefore, during use, if the tooth shapes of the synchronous wheel and the synchronous belt are not completely matched, the synchronous belt will wear out. When the wear is severe, it will lead to failure to transmit, affecting use. Among them, a synchronous wheel with application number "CN202222805290.X" is provided. The utility model divides the synchronous wheel into two coaxial parts, an inner ring and an outer ring, and the hardness of the outer ring is less than that of the inner ring. The synchronous wheel not only meets the rigidity requirements of connecting with the output shaft of the power mechanism under heavy load and high-speed transmission conditions, but also avoids the wear of the synchronous belt due to excessive hardness when meshing with the synchronous belt. However, there is still room for improvement in the use of the synchronous wheel: since the width of the synchronous wheel is fixed, it is impossible to adjust the use width of the synchronous wheel compared with the traditional synchronous wheel with a fixed retaining ring, so that the synchronous wheel can only correspond to the use of a synchronous belt of one width, thereby reducing the applicability of the synchronous wheel. Utility Model Content

[0003] The purpose of the utility model is to provide an adjustable synchronous wheel to solve the problem raised in the above-mentioned background technology that the width of the synchronous wheel is fixed, and the use width of the synchronous wheel cannot be adjusted, so that the synchronous wheel can only correspond to the use of a synchronous belt of one width, thereby reducing the applicability of the synchronous wheel.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable synchronous wheel, comprising a mounting shaft, an adjusting mechanism and a pushing mechanism;

[0005] Wherein: a mounting hole is opened in the middle of the mounting shaft, a fixing pin hole is opened through the surface of one end of the mounting shaft, a synchronous wheel is installed in the middle of the surface of the mounting shaft, and a transmission tooth is arranged around the surface of the synchronous wheel;

[0006] The adjustment mechanism comprises a fixed ring installed on one side of the synchronous wheel, a movable ring is provided on the other side of the synchronous wheel, a tooth groove is provided on the inner wall of the movable ring, and the transmission teeth slide in the tooth groove provided on the inner wall of the movable ring;

[0007] The pushing mechanism includes a threaded groove opened on the surface of the other end of the installation shaft, and a rotating sleeve is provided at the other end of the installation shaft. The rotating sleeve is threadedly connected to the surface of the threaded groove, and an annular groove is opened on the inner side of the rotating sleeve. The outer side of the moving ring is connected to multiple push rods, and the push rods are inserted into the annular groove.

[0008] As a preferred solution of the utility model: the outer edge of the annular groove is fixedly connected to a limiting ring, the end surface of the push rod is provided with a limiting groove, and the limiting ring is inserted into the limiting groove.

[0009] As a preferred solution of the utility model: an anti-slip ring is fixedly installed at the other end of the installation shaft.

[0010] As a preferred solution of the utility model: a plurality of anti-slip grooves are provided on the surface of the rotating sleeve.

[0011] As a preferred solution of the utility model: the push rod is a metal rod body.

[0012] As a preferred solution of the utility model: the surface of the thread groove and the rotating sleeve are both coated with grease.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) A synchronous wheel is installed in the middle of the surface of the mounting shaft, a fixed ring is installed on one side of the synchronous wheel, and a moving ring is installed on the other side of the synchronous wheel. When the use width of the synchronous wheel needs to be adjusted, the moving ring is pushed to move on the synchronous wheel, so that the moving ring slides on the transmission teeth on the surface of the synchronous wheel through the tooth grooves provided on the inner wall, thereby adjusting the spacing between the moving ring and the fixed ring, and adjusting the use width of the synchronous wheel, which is convenient for installing and using synchronous belts of different widths, thereby increasing the application range of the synchronous wheel and eliminating the need to replace the synchronous wheel;

[0015] (2) A threaded groove is provided on the other end surface of the mounting shaft through a push mechanism, and the rotating sleeve is threadedly installed on the threaded groove surface. An annular groove is provided on the inner side of the rotating sleeve, and multiple push rods installed on the outer side of the moving ring are inserted into the annular groove. Since the outer edge of the annular groove is connected to a limiting ring, a limiting groove is provided on the end of the push rod. The limiting ring is inserted into the limiting groove, so that a rotational connection is achieved between the rotating sleeve and the push rod. When the rotating sleeve moves on the threaded groove surface, the rotating sleeve drives the moving ring to approach or move away from the fixed ring through the push rod, so as to drive the moving ring to move and adjust.
