Embodiment Construction

[0026] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so as to highlight the technical solutions and beneficial effects of the present invention.

[0027] See figure 1 The torque transmission assembly 100 of an embodiment of the present invention includes a drive shaft 10, an output shaft 20, and a coupling 30 for coaxially connecting the output shaft 20 to the drive shaft 10. The drive shaft 10 may be a rotating shaft of a motor, and the output shaft 20 may be a worm of a gear set. The torque of the drive shaft 10 is transmitted to the output shaft 20 through the coupling 30. The drive shaft 10 and the output shaft 20 are both elongated, but in the drawings, in order to make the drawing more clear, only a part of the drive shaft 10 and the output shaft 20 are shown in the drawings.

[0028] See also figure 2 and image 3 The drive shaft 10 includes a cylindrical shaft body 11 and a mounting porti...

Abstract

The present invention provides a torque transmission combination device, which includes a first rotating shaft, a second rotating shaft and a coupling, the coupling includes a first connecting piece and a second connecting piece, the first connecting piece is connected to the The first rotating shaft is connected and can rotate synchronously with the first rotating shaft, the second connecting member is connected with the second rotating shaft and can rotate synchronously with the second rotating shaft, the first connecting member includes a base and cannot The metal coupling piece detachably combined in the base, the coupling piece is directly connected with the first rotating shaft, the base includes several protrusions extending along the axial direction of the coupling, the protrusions Outlets are spaced apart from each other along the circumferential direction of the coupling, and the second connecting member includes a body and a plurality of driving arms extending from the body along the radially peripheral side wall of the coupling, and the driving arms are along the shaft coupling. Extending radially, the driving arm is clamped between two adjacent protrusions of the first connecting part, so that the first connecting part and the second connecting part can rotate together.

Description

Technical field [0001] The invention relates to a torque transmission combined device and a coupling used in the same. Background technique [0002] The existing coupling usually includes two connecting pieces with the same structure and a buffer piece sandwiched between the two connecting pieces. Each connecting member usually includes a base and a plurality of connecting arms extending from the base to another connecting member. The buffer member usually includes a circular ring and a plurality of buffer arms extending radially outward from the outer side of the circular ring. Each buffer arm is sandwiched between a connecting arm of the two connecting pieces and the circular ring is surrounded by the connecting arm. The motor shaft is connected to a base, and the other base is connected to an output shaft. In this way, the motor shaft transmits torque to the output shaft through the coupling. However, each connecting piece has a base, which results in a large axial length o...
