Unidirectional rotating device for achieving large rotating angle and high torque

Abstract

The invention relates to a unidirectional rotating device and belongs to the field of mechanical transmission. The unidirectional rotating device for achieving a large rotating angle and a high torque is characterized in that the unidirectional rotating device comprises a gear arranged in the middle, the two ends of the gear are each coaxially connected with a one-way bearing through a coupling part, the outer diameter of the gear is smaller than the outer diameter of each one-way bearing, and the two one-way bearings are stressed in the same direction; and the axis of the gear is hollow, a center connecting shaft of the two one-way bearings penetrates through the axis of the gear in a non-contact mode, and thus the two one-way bearings are coaxially connected. According to the unidirectional rotating device, through the structural form that the large-diameter one-way bearings are coaxially installed at the two ends of the small-diameter gear in the middle, excursion displacement is converted into large-rotating-angle rotating displacement through the small-diameter gear, the high torque is shared since the large-diameter one-way bearings at the two ends are stressed in the same direction, and thus large-rotating-angle and high-torque unidirectional rotation is achieved.

Description

technical field [0001] The invention relates to a one-way rotating device, in particular to a one-way rotating device capable of realizing large rotation angle and high torque. Background technique [0002] Current one-way rotating devices generally use one-way bearings, and the rated torque of one-way bearings is an important parameter, and its rated torque is proportional to its diameter. Therefore, when the amplitude is small and the vibration force is large, when using a small-diameter one-way bearing to convert the linear amplitude displacement into rotational displacement, although the rotation angle is large, the rotational torque that can be tolerated is small. When the vibration force exceeds its rated One-way bearings are prone to failure after torque is applied. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a one-way rotation device with large rotation angle and high torque, which can realize the on...
