Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering, and in particular to a lightweight geared motor. Background Technology

[0002] Lightweight geared motors are core components that integrate power output and transmission conversion. Through a reduction mechanism, they convert high-speed motors to low-speed motors and amplify torque, while simultaneously reducing their own weight through a lightweight design. They provide precise, efficient, and stable power drive for fields such as industrial automation, new energy, aerospace, consumer electronics, and medical equipment, meeting the dual requirements of power performance and lightweight design in different scenarios.

[0003] Existing lightweight geared motors use a combination of heavy shafts and bearings, without considering the lightweight design of the device or the flexible braking after the motor is powered off, which seriously affects the performance. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art by providing a lightweight geared motor. This aims to improve the technical problems of existing lightweight geared motors in use, such as the lack of consideration for the lightweight design of the device and the lack of consideration for the flexible braking of the motor after power failure.

[0005] This utility model also provides a lightweight geared motor, comprising: a lightweight housing with a mounting chamber 1; a gearbox housing mounted on the outer surface of the lightweight housing, the gearbox housing having a mounting chamber 2 inside, the mounting chamber 2 having a mounting through hole 2 inside; a PTFE-coated gasket, the PTFE-coated gasket utilizing the low friction and corrosion resistance properties of PTFE to prevent media leakage through sealing surface adhesion, and also providing lubrication (this method is existing technology), mounted on the inner surface of the mounting through hole 2; a lightweight bearing tightly attached to the outer surface of the PTFE-coated gasket; a hollow alloy steel output shaft rotatably connected to the inner surface of the lightweight bearing; a circular brake disc fixedly connected to the side surface of the hollow alloy steel output shaft; and a mechanical brake assembly attached to the outer surface of the circular brake disc. The mechanical brake assembly uses calipers to push brake pads to clamp the disc, using friction to convert kinetic energy into heat energy for braking (this method is existing technology). Through the combined use of these components, a lightweight device structure is achieved, allowing for flexible manual braking after power failure, and smooth operation with slow heating.

[0006] According to the lightweight geared motor provided in this utility model, the outer surface of the lightweight bearing is tightly fitted with the inner surface of the mounting chamber two, the inner surface of the mechanical brake assembly is fixedly connected to a perforated mounting platform, and the inner surface of the perforated mounting platform is fixedly connected to a gearbox housing. Through the coordinated use of these components, a lightweight device structure is achieved.

[0007] According to the lightweight geared motor provided in this utility model, an output shaft assembly is fixedly connected to the inner surface of the hollow alloy steel output shaft. A gear set meshes with the inner surface of the output shaft assembly, and the gear set transmits power through planetary gear meshing, reducing the rotational speed while proportionally increasing the torque. This method is existing technology. A rotor meshes with the gears on the inner surface of the other end of the gear set. Through the coordinated use of these components, a lightweight device structure is achieved.

[0008] According to the lightweight geared motor provided in this utility model, a lightweight bearing and a silicone sealing ring are rotatably connected to the inner end surface of the rotor. Through the combined use of these components, a lightweight device structure is achieved.

Both the lightweight bearing and the PTFE-coated sealing gasket are coated with long-lasting grease. Through the coordinated use of these components, a reasonable device structure and heat prevention effect are achieved.

[0010] According to the lightweight geared motor provided in this utility model, the interior of the lightweight housing is provided with a mounting chamber and a mounting through hole. Through the combined use of these components, the effect of lightweight device structure is achieved.

[0011] According to the lightweight geared motor provided in this utility model, a stator is fixedly connected to the inner surface of the mounting chamber, and a rotor is rotatably connected to the inner surface of the mounting through hole. Through the coordinated use of these components, a rationally structured device is achieved.

[0012] According to the lightweight geared motor provided in this utility model, an encoder runs through the interior of the lightweight housing, and terminals are welded to the outer surface of the encoder. Through the coordinated use of these components, a lightweight structure and a rational layout are achieved.

[0013] Beneficial effects Compared with existing technologies, this lightweight geared motor, without altering the original performance of the equipment, utilizes a lightweight housing, a hollow alloy steel output shaft, lightweight bearings, silicone seals, and PTFE-coated gaskets to significantly reduce the weight of the device. A circular brake disc and mechanical brake assembly allow for flexible control of the output end to stop or continue inertial motion after operation ceases. The lightweight bearings, PTFE-coated gaskets, and long-lasting lubricant provide excellent heat prevention, ultimately achieving a lightweight structure, flexible manual braking after power failure, smooth operation, and slow heat generation.
