Description

Technical Field

[0001] This utility model relates to an improvement in the structure of a logistics equipment, specifically an electric roller coupling structure. Background Technology

[0002] The electric roller is the main working device with operating power in a power conveyor. It drives other unpowered rollers to run synchronously through a transmission device to achieve the purpose of rolling conveying. The electric roller itself has a motor and a reduction gear, enabling it to drive itself. The electric roller will frequently start and stop according to the requirements of the conveying work. The existing structure connects the output shaft of the reduction gear to the connecting wheel at the end of the roller. A soft pad can be placed between the connection structure. However, frequent start and stop will repeatedly squeeze the soft pad. The soft pad has a small force-bearing area, which leads to deformation and failure. If no soft pad is added, the structural wear and damage will occur due to the excessive clearance of the shaft drive. Therefore, it is necessary to improve the output structure of the electric roller. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned deficiencies in the prior art and to provide an electric drum coupling structure.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: The coupling structure includes a motor-side lead-out shaft, an end-fixed lead-out shaft, and a perforated washer. The motor-side lead-out shaft is fixedly connected to the end face of the drum motor. The end-fixed lead-out shaft is set as the outer end fixed shaft of the drum. The motor-side lead-out shaft and the end-fixed lead-out shaft are axially aligned and lined with perforated washer. The motor-side lead-out shaft, the end-fixed lead-out shaft, and the perforated washer are all provided with lead-out holes, and the lead-out holes are interconnected. The wires of the drum motor are connected to the outer end of the drum through the lead-out holes. The coupling structure is set at the end of the drum motor body and serves as the end shaft fixed structure of the drum. The coupling is an axially aligned structure with perforated washer, forming a stable axial connection, realizing the stability of the working foundation of the electric drum, ensuring the stability of the rotational transmission, and allowing the motor wires to be led out nearby for convenient wiring and routing.

[0005] Furthermore, both the motor-side output shaft and the end-fixed output shaft are formed with coupling discs. Each coupling disc has a flat disc body and three circumferentially distributed jaws. The inner inclined surface of each jaw is arc-shaped. The jaws of the two coupling discs are staggered and interlocked. A filling space is provided between adjacent jaws, and a perforated pad is placed within this space. The perforated pad has six segments and is pressed tightly against the adjacent jaw surfaces. The coupling discs form the structural basis for the mutual engagement of the two components. They are connected through the interlocking jaws, and the perforated pads, which are elastic and can deform to a certain extent to reduce vibration, are placed between the rigid contact surfaces. The perforated pads have a stable thickness, can fill the space, and have sufficient elasticity to achieve a stable connection.

[0006] Furthermore, the plum blossom pad is made of rubber, and the surfaces of the plum blossom pad's segments that contact the coupling discs on both sides are provided with gap protrusions. These gap protrusions support and maintain the torsional gap between the plum blossom pad and the coupling disc surfaces. The plum blossom pad uses a highly elastic rubber material, which is durable. The gap protrusions at its connection with the coupling disc form a torsional gap. This torsional gap allows the plum blossom pad sufficient elastic deformation space to accommodate concentricity errors during roller operation, achieving redundancy in operational errors and enabling self-torsional correction during operation, thus improving operational reliability.

[0007] Furthermore, the coupling disc on the motor-side output shaft has a claw on one side and a flat surface on the other, which is fixedly connected to the roller motor. Mounting holes are provided on the claws, and screws are connected into these holes to secure it to the roller motor. The motor-side output shaft has a straight connecting surface and is directly fixedly connected to the roller motor, forming a coupling base on one side.

[0008] Furthermore, the coupling disc for fixing the end output shaft has a chuck on one side and a mounting shaft on the other side. The mounting shaft is installed and connected to the frame of the roller conveyor. A rolling bearing is connected to the mounting shaft and sleeved with the outer cylinder of the roller. The end output shaft is fixed to one side, and the shaft end is fixed by the mounting shaft, and it is rotatably connected to the outer cylinder of the roller through the rolling bearing.

[0009] Compared with the prior art, this utility model has the following advantages and effects: This design is an improvement on the connection of the power device of an electric drum. The motor inside the electric drum is connected to the outer shaft of the drum through a coupling, so as to achieve a reliable axial connection, reduce the structural wear of the motor caused by frequent start and stop, extend its service life, and withstand the requirements of high load operation, thereby improving product quality.
