When the bearings and gears are installed and fixed, it is difficult to ensure the accuracy of the bearing positioning, and the bearings need to be repeatedly adjusted and fixed, which reduces the installation efficiency of the bearings. Therefore, it is of great significance to design a dual-bearing gear. Summary of the Invention

[0004] The purpose of the utility model is to provide a dual-bearing gear in order to solve the above problems in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a dual-bearing gear, characterized in that it includes a rotating shaft and a gear part arranged on the rotating shaft, two bearing parts are arranged on the rotating shaft, and the two bearing parts are respectively located on both sides of the gear part, a positioning assembly is arranged between the gear part and the bearing part, the positioning assembly includes a guide block arranged on the side of the inner ring of the bearing part, and a guide groove for docking the guide block is opened on the side of the gear part.

[0006] In the above-mentioned dual-bearing gear, a slide bar is movably provided on the guide block, one end of the slide bar is fixedly connected to a positioning block, and a positioning groove for engaging the positioning block is provided on the rotating shaft.

[0007] In the above-mentioned dual-bearing gear, the guide block is provided with a movable groove for limiting the movable position of the positioning block, a spring is fixedly arranged between the positioning block and the movable groove, and a control block fixed to one end of the slide rod is arranged on the side of the guide block.

[0008] Compared with the existing technology, this dual-bearing gear positioning assembly can pre-position the bearings and gears, making the installation and positioning of the bearings and gears more accurate, thereby facilitating the installation of the bearings and gears and improving the installation efficiency of the bearings and gears.

[0010] Figure 2 It is a schematic diagram of the cross-sectional structure of the dual-bearing gear.

[0011] In the figure, 1, rotating shaft; 2, gear part; 3, bearing part; 4, positioning assembly; 5, guide block; 6, guide groove; 7, slide rod; 8, positioning block; 9, positioning groove; 10, movable groove; 11, spring; 12, control block. DETAILED DESCRIPTION

[0012] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0013] like Figure 1 、 2 As shown, the dual-bearing gear includes a rotating shaft 1 and a gear member 2 arranged on the rotating shaft 1. Two bearing members 3 are provided on the rotating shaft 1, and the two bearing members 3 are respectively located on both sides of the gear member 2. A positioning component 4 is provided between the gear member 2 and the bearing member 3. The positioning component 4 includes a guide block 5 provided on the side of the inner ring of the bearing member 3. A guide groove 6 for docking with the guide block 5 is opened on the side of the gear member 2. Through the positioning component 4, before the bearing and the gear are fixed, the positioning component 4 can pre-position the bearing and the gear, so that the installation positioning of the bearing and the gear is more accurate, thereby making it easier to install the bearing and the gear, and improving the installation efficiency of the bearing and the gear.

[0014] Preferably, a slide rod 7 is movably provided on the guide block 5, one end of the slide rod 7 is fixedly connected to a positioning block 8, and a positioning groove 9 for the positioning block 8 to be engaged is provided on the rotating shaft 1. The movement of the positioning block 8 is controlled by the slide rod 7, and the slide rod 7 is controlled to make the positioning block 8 cooperate with the positioning groove 9.

[0015] Preferably, a movable groove 10 for limiting the movable position of the positioning block 8 is provided on the guide block 5, a spring 11 is fixedly arranged between the positioning block 8 and the movable groove 10, and a control block 12 fixed to one end of the slide rod 7 is provided on the side of the guide block 5. The spring 11 can exert a force on the positioning block 8, so that the positioning block 8 is snapped into the positioning groove 9. The operation control block 12 can pull the positioning block 8 to squeeze the spring 11, so that the positioning block 8 is disengaged from the positioning groove 9.

[0016] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.

[0017] Although this document frequently uses terms such as rotating shaft 1, gear member 2, bearing member 3, positioning assembly 4, guide block 5, guide groove 6, slide bar 7, positioning block 8, positioning groove 9, movable groove 10, spring 11, and control block 12, the use of other terms is not excluded. These terms are used solely to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitations is contrary to the spirit of the present invention.
