Description

Technical Field

[0001] The utility model relates to the field of mechanical shafts, in particular to a mechanical shaft that is easy to install. Background Art

[0002] A mechanical shaft, as the name suggests, is a shaft used to connect product components and enable them to rotate. It not only supports rotating parts, but also withstands bending and torque during rotation. The main functions of the shaft include supporting rotating elements (such as gears, eccentric wheels, flywheels, etc.), transmitting rotational motion to other components, and in some cases adjusting position and reducing vibration. The shaft is a mechanical part that supports rotating parts and rotates with them to transmit motion, torque or bending moment. It is generally a metal round rod, and each section can have different diameters. The parts that perform rotational motion in the machine are mounted on the shaft.

[0003] The existing mechanical shaft is installed on the bearing seat during use. During installation, the mechanical shaft usually removes the bearing seat and puts it on the shaft, and then installs the bearing seat. When disassembling and replacing, the bearing seat needs to be disassembled, which is troublesome and the shaft cannot be directly removed.

[0004] Therefore, we propose a mechanical switch that is easy to install. Utility Model Content

[0005] The purpose of the utility model is to provide a mechanical shaft that is easy to install. The device has the advantages of being able to be disassembled in sections, which is more convenient and easy to install and disassemble.

[0006] The purpose of the utility model is to provide a mechanical shaft that is easy to install, including a shaft body, two connecting shafts are spline-connected on both sides of the shaft body, multiple racks for limiting are fixedly connected in the spline grooves on the surfaces of the two connecting shafts, multiple mounting slots in a circular array are opened at the spline connections on the inner walls of both sides of the shaft body, and multiple gears rotatably connected to the shaft body are rotatably connected in the multiple mounting slots, the multiple gears and the multiple racks are engaged with each other, and limiting mechanisms for limiting and fixing the gears are installed on both sides of the shaft body.

[0007] Furthermore, key pin grooves for connection are provided on both sides of the surfaces of the two connecting shafts.

[0008] Furthermore, the length between the two connecting shafts can be adjusted by sliding on both sides of the shaft body.

[0009] Furthermore, the limiting mechanism includes multiple limiting bars slidably connected to both sides of the shaft body, step grooves are opened on both sides of the shaft body, and two clamping rings are slidably connected to the step grooves to fix the multiple limiting bars, and multiple limiting bars in a ring array are fixedly connected to one side of the two clamping rings.

[0010] Furthermore, the plurality of limit bars are engaged and fixed with the plurality of gears.

[0011] Furthermore, thread grooves for fixing are provided on the surfaces of the step grooves on both sides of the shaft body, and two nuts are respectively threadedly connected to the surfaces of the thread grooves.

[0012] The two gears are engaged with each other and are fixed on the two connecting shafts by means of the two nuts, which are then threaded onto the surface of the threaded grooves on both sides of the shaft, so that the two nuts are fixed to the two nuts, thereby completing the fixation of the gears. This allows for easy length adjustment and adaptability to different scenarios. The two gears can be disassembled in sections, which is more convenient and easier to install and disassemble.

[0013] Compared with the prior art, the beneficial effect of the present invention is that when the two connecting shafts need to be installed or disassembled, the limiting mechanism is loosened and the two connecting shafts are slid so that the two connecting shafts drive multiple racks to move in the inner wall of the shaft body. At the same time, the multiple racks drive multiple gears to rotate, so that the two connecting shafts are disengaged from both sides of the inner wall of the shaft body to complete the disassembly. The length between the two connecting shafts can be changed according to the distance between the two connecting shafts and the two sides of the sliding shaft body, and then the gears can be fixed to facilitate length adjustment to adapt to different scenarios. It can be disassembled in sections, which is more convenient and easy to install and disassemble.
