Description

Technical Field

[0001] The utility model relates to the technical field of electric roller equipment, in particular to a cam electric roller. Background Art

[0002] Cam electric roller is a mechanical transmission device, usually used for material conveying, positioning on production lines, steering or other occasions that require rotation or propulsion. It combines the characteristics of electric drive and cam mechanism, and realizes specific movement or function by driving the cam.

[0003] At present, the cam motor rollers on the market use traditional welding or riveting technology to connect the cam mounting seat with the motor roller, so that the cam mounting seat and the cam are driven to rotate by the motor roller. Traditional welding is not easy to install. During the production process, workers may not weld in place or offset, which may easily cause the built-in bearing to be squeezed and damaged, increase production costs, reduce production efficiency, and be difficult to disassemble and repair. The riveting process uses positioning rivets to rivet the cam mounting seat and the motor roller together, which has low production efficiency. When subjected to large torque loads during use, the riveted joints are easily broken, resulting in connection failure.

[0004] In view of this, we propose a cam electric roller to solve the existing problems. Utility Model Content

[0008] Preferably, the drive motor is provided with an output shaft at one end close to the reduction gearbox, and is meshedly connected to the gearbox through the output shaft. The output end of the gearbox drives the drive ring and the tolerance ring to rotate through the drive frame, thereby driving the outer shell to rotate. The outer shell rotates and drives the cam seat to rotate through the tolerance rings installed on the cam seats at both ends thereof.

[0009] Preferably, a first mounting groove is provided at the center of one end of the cam seats at both ends close to the shell, and a second mounting groove is provided at the other end. Bearings are provided in the first mounting groove and the second mounting groove. A lead wire is provided at one end of the cam seat on one side of the driving motor close to the shell, and the lead wire passes through the center of the bearing and extends to the outside of the cam seat. A connecting shaft is rotatably connected to the central axis of the cam seat on the other side through a bearing.

[0010] Preferably, a cam is fixedly sleeved on the outer ring of the cam seats at both ends away from one end of the housing.

[0011] Preferably, an end of the connecting shaft away from the cam seat is provided with a connecting groove concave toward the shaft body of the connecting shaft along the axial direction.

[0012] Preferably, the tolerance ring is made of wear-resistant material.
