Description

Technical Field

[0001] This utility model relates to the field of transmission technology, specifically to a low-speed balancing machine drive device. Background Technology

[0002] Low-speed dynamic balancing machines are widely used in the transmission manufacturing industry, enabling rotating parts to operate with low vibration. Since low-speed dynamic balancing machines must adapt to various types of rotating parts, their drive motors should be able to adapt to rotating parts with both low speed and large moment of inertia, as well as high speed and small moment of inertia. For this reason, the drive motor should be able to achieve a large torque output at low speed and a small torque output at high speed at the same output shaft, and it is necessary to shift between the two. Traditional shifting structures must contain spline sliding structures. However, spline sliding structures have high requirements for machining accuracy, are more complex in structure, and are prone to wear and inconvenient to maintain over long-term use.

[0019] The rotating sleeve and the second gear shaft are radially positioned by two deep groove ball bearings and axially positioned by a thrust ball bearing.

[0020] The thrust ball bearing is axially fixed to the second gear shaft by two halves of retaining rings;

This simplifies the connection process of external equipment, avoids repeated calibration or adaptation problems caused by the adjustment of the transmission structure, and improves operating efficiency.

[0029] Furthermore, the coaxial design of the gear shaft and the rotating sleeve reduces redundant components (such as the complex gear sets of traditional gearboxes), making the overall structure more compact and reducing the weight of the gearbox, which facilitates equipment integration and maintenance.
