Description

Technical Field

[0001] This utility model relates to the field of shaking machine technology, specifically to an electric drive structure for horizontal rhythmic output of a shaking machine. Background Technology

[0002] A vibrating machine is a device that generates horizontal (backward or left-right) vibration or rhythm. It is commonly used in fitness, physiotherapy or rehabilitation fields. Its core objective is to convert the rotational motion of a motor into the horizontal reciprocating motion of a platform.

[0003] Existing shaking machines rely on the direct forward and reverse rotation of the motor to drive the platform's horizontal reciprocating motion. This frequent starting, stopping, and reversing generates enormous inertial impact forces, which not only easily lead to rapid wear and fatigue fracture of transmission components (such as belts, bearings, and connectors), but also shorten the lifespan of the motor itself and generate significant noise and vibration. Utility Model Content

[0004] The purpose of this utility model is to provide an electric drive structure for the horizontal rhythmic output of a shaking machine, so as to solve the problem mentioned in the background art that the frequent start-stop and reversal will generate huge inertial impact force, which will not only easily lead to rapid wear and fatigue fracture of transmission components, but also shorten the life of the motor itself, and generate greater noise and vibration.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electric drive structure for horizontal rhythmic output of a shaking machine, comprising a plastic shell and a conveyor belt, wherein two sets of plastic shells are symmetrically arranged and located on both sides of the conveyor belt respectively; Also includes: A roller assembly is installed between two sets of plastic housings, with the roller assembly located at both ends of the inner side of the conveyor belt. A motor is installed inside the plastic housing and is fixed to the inner wall of the plastic housing by a fastener. A transmission wheel assembly is installed inside the plastic housing on the side near the motor. A second belt is sleeved on the drive shaft at the front end of the motor, and the other end of the second belt is connected to the transmission wheel assembly. The transmission wheel assembly and the roller assembly are connected by a first belt. A transmission metal component is installed inside the plastic housing on one side of the transmission wheel assembly.

[0006] Preferably, the roller assembly includes a synchronous pulley roller and a driven roller, which are respectively installed at both ends inside the conveyor belt, and the first belt is connected to a connecting wheel at one end of the synchronous pulley roller.

[0007] Preferably, the transmission wheel assembly consists of a first bearing, a bearing rod, a second bearing, a pulley, and an elastic retaining ring. The two ends of the bearing rod are respectively installed inside the plastic housing through the first bearing and the second bearing. The pulley is installed outside the bearing rod. The elastic retaining ring is engaged with the bearing rod at one end of the second bearing. The second belt is connected to the large disc of the pulley, and the first belt is connected to the small disc of the pulley.

[0008] Preferably, a first metal limiting member is provided inside the plastic shell, and the first metal limiting member is located between the transmission metal member and the pulley; a second metal limiting member is provided inside the plastic shell, and the second metal limiting member is located on the other side of the transmission metal member.

[0009] Preferably, a spring is installed between the transmission metal component and the first metal limiting component, and a bolt is installed on the inner side of the transmission metal component, with one end of the bolt passing through the spring and contacting the first metal limiting component without contact.

[0010] Compared with the prior art, the beneficial effects of this utility model are: (1) The transmission wheel set, roller set and conveyor belt are driven by the inertia of the motor in forward and reverse rotation, instead of relying on the instantaneous start / stop / reversal of the motor to provide all the power. The speed change of the transmission wheel set also helps to smooth the torque change, which greatly reduces the impact force on the motor and transmission components at the reversal point, effectively reduces wear, significantly extends the service life of core components such as motor, belt, and bearing, and reduces operating noise. The design of the transmission wheel set connects the motor and the large pulley of the pulley through the second belt, and the small pulley of the pulley and the synchronous pulley roller through the first belt. This speed change mechanism can adjust the torque and speed output to the roller as needed, so that the motor can work more efficiently in the appropriate load range, reduce energy consumption, and improve system response and motion stability.

[0011] (2) At the key stress points inside the plastic shell, namely around the transmission wheel assembly, the first metal limiting component, the second metal limiting component, and the transmission metal component are installed. These metal components bear the main constraint force, impact force, and guiding force, effectively sharing the load of the plastic shell, preventing the plastic components from deforming or cracking under long-term impact, greatly improving the rigidity and durability of the overall structure, and ensuring the reliability of the equipment's long-term operation. Under the combined action of the spring, the first metal limiting component, and the second metal limiting component, the transmission metal component can make small movements in the axial direction, playing a role in tensioning and compensation. The spring provides preload and buffer, and the limiting component restricts its range of movement. Attached Figure Description
