Description

Technical Field

[0001] The present application belongs to the field of reducer components, and specifically relates to a reducing gear that can be used in a reducer. Background Art

[0002] A reducer is a speed reduction transmission device used between the prime mover and the working machine, and is widely used in modern machinery. Common reducers usually use a small gear to drive a large gear to achieve a deceleration effect, and play the role of transmitting torque between the prime mover and the working machine or actuator.

[0003] As the core component of the reducer, lightweighting of transmission gears is one of the development directions of modern mechanical engineering. Currently, transmission gears usually reduce their own weight by changing their materials. For example, alloy materials such as aluminum alloy or titanium alloy are used instead of traditional steel materials. However, this will inevitably increase the manufacturing cost of transmission gears significantly. Utility Model Content

[0004] Based on the content in the background technology, the present application optimizes the existing transmission gear in terms of structural design to ensure that it can withstand a larger torque load and power output while being lightweight.

[0005] A reducing gear for a speed reducer is provided, wherein an annular groove is provided in the middle of the inner ring surface of the gear, a plurality of limit slots are provided axially on the inner ring surface of the gear, and the plurality of limit slots are evenly distributed around the circumference, and at least one threaded hole is provided between adjacent limit slots on the end surface of the gear. Of course, both end surfaces of the gear are provided with threaded holes in this manner, and a sector gear ring is fixedly connected to the outer ring surface of the gear. The limit slots and threaded holes of the reducing gear enable it to be connected to two Figure 3 The connector shown in the figure is assembled and connected, so that the subtractive gear transmission is stable and can withstand greater torque load and power output. The specific assembly and connection method is as follows: when the end of the connector is placed on the inner ring of the subtractive gear, the limit block of the connector is placed in the limit groove corresponding to the subtractive gear, and the fastening bolt passes through the flange hole of the connector and is screwed into the threaded hole corresponding to the subtractive gear. The assembled schematic diagram is shown in Figure 4 ;

[0006] The above-mentioned material-reducing gear structure is specifically cast in one piece. The annular groove and limit groove opened can reduce the weight of the material-reducing gear while meeting the assembly requirements. Its fan-shaped ring gear can be suitable for the angle adjustment requirements within a specific range and can also reduce the overall weight. Such a lightweight material-reducing gear not only saves manufacturing materials and reduces manufacturing costs, but also can improve transmission efficiency by reducing its own load.

[0007] Preferably, six limit slots are axially provided on the inner ring surface of the gear, and the six limit slots are evenly distributed around the circumference. Two threaded holes are respectively provided on the end face of the gear between each adjacent limit slots. Such evenly distributed number of limit slots and threaded holes enables the weight-reducing gear to achieve a better balance in weight and structural strength, and can transmit smoothly.

[0008] Furthermore, an arcuate groove is provided on the bottom surface of the annular groove, which can reduce material and avoid air, thereby further reducing the weight of the material-reducing gear and improving the manufacturing process and cost.

[0009] Through the above technical solution, the utility model has at least the following beneficial effects:

[0010] The reduction gear that can be used for the reducer described in this application, through its structural design, has the characteristics of being lightweight while meeting the transmission assembly requirements of being able to withstand greater torque loads and power outputs. It not only saves manufacturing materials and reduces manufacturing costs, but also improves transmission efficiency by reducing its own load. BRIEF DESCRIPTION OF THE DRAWINGS
