Description

Technical Field

[0001] The utility model relates to the technical field of machine tool shaft drivers, in particular to a symmetrically driven machine tool shaft driver. Background Art

[0002] A symmetrically driven machine tool spindle driver is a mechanical transmission device with dual-side drive. It typically uses two symmetrically distributed motors or other drive sources to drive the spindle, ensuring balanced and stable loads during rotation. A symmetrically driven machine tool spindle driver primarily consists of a supporting housing, a high-speed drive assembly, and a low-speed drive assembly. Due to the presence of two drivers, symmetrically driven machine tool spindle drivers generate significant heat over time. Using a heat sink to dissipate heat is ineffective, potentially causing damage to the device.

[0003] A Chinese patent discloses a symmetrically driven machine tool shaft driver (authorization announcement number CN206839695U). The patented technology mainly includes a supporting shell, in which a high-speed drive component and a low-speed drive component are arranged; the low-speed drive component includes a low-speed input shaft, and the axial ends of the low-speed input shaft are rotatably connected to the inside of the supporting shell, wherein a drive sleeve A is coaxially fixedly connected to the low-speed input shaft, and a plurality of groups of drive gears A are arranged in a linear array on the drive sleeve A, and a power output shaft is rotatably connected to the bottom of the supporting shell through a bearing assembly, and a plurality of groups of driven gears A are arranged in a linear array on the power output shaft, and the drive gears A and the driven gears A are meshed with each other; the high-speed drive component includes a high-speed rotating shaft, and a plurality of drive gears B are arranged in a linear array on the high-speed rotating shaft, and a plurality of driven gears B are arranged in a linear array on the power output shaft, and the driven gears B are rotatably connected to the power output shaft through bearings, and the driven gears B and the driven gears A are staggered.

[0004] However, this patent still has some shortcomings. The symmetrically driven machine tool spindle driver, due to the presence of two drivers, generates a large amount of heat during long-term use. Using a heat sink to dissipate heat is ineffective, which can easily damage the device. Therefore, those skilled in the art have provided a symmetrically driven machine tool spindle driver to address the problems raised in the background art. Utility Model Content
