Embodiment Construction

[0022] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention are clearly and completely described below in conjunction with specific embodiments and with reference to the accompanying drawings. Obviously, the described embodiments are part of the implementation of the present invention. example, not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0023] Such as figure 1 As shown, the present embodiment provides a rotational bias driving mechanism, which includes a fixed frame 1 and a rotating frame 2 whose surfaces are parallel to each other, and the fixed frame 1 is fixedly provided with a support member 3 and a driving frame connected to the rotating frame 2 respectively. Part 4, the rotating frame 2 can freely...

Abstract

The invention provides a rotating bias drive mechanism. The mechanism comprises a fixed frame and a rotating frame, the surfaces of the fixed frame and the rotating frame are parallel to each other, asupporting component and a driving component which are connected with the rotating frame are fixedly arranged on the fixed frame, and the rotating frame can freely rotate in a plane relative to the supporting component and the driving component. The driving component comprises driving shafts matched with the rotating frame, the positions of the driving shafts can be changed in the rotating planeof the rotating frame under the action of the driving component, and the driving component can lock the positions of the driving shafts. The mechanism has the advantages that two rotating centers areprovided for the rotating frame, and the position of one driving shaft is changed by the driving component, so that the rotating frame rotates relative to the supporting component in the plane, the influence of eccentric force on the service life of the rotating shaft under the condition of a single rotating shaft is overcome, the stability is improved, and the service life is prolonged; and the driving shafts can be fixed at any position within the moving range, so that the rotating frame cannot shake in the using process, and safety is improved.

Description

technical field [0001] The invention relates to the technical field of rotary drive mechanisms, in particular to a rotary bias drive mechanism. Background technique [0002] With the increase of the aging population, there are more and more people with limited mobility. Many patients can only stay in bed for a long time. Nursing and other work; the existing equipment mostly adopts the structure of motor direct drive, or the motor, reducer and rotating shaft adopt a series structure, which occupies a large space in the axial direction and requires a large installation space. Some equipment uses a rotating shaft and a reducer in series. The input shaft of the reducer and the motor are driven by a synchronous belt drive, and the central axis of the rotating shaft is the input point of the maximum torque position. To meet the torque demand, a larger reducer is required. There is no doubt that the cost will increase, and the large torque reducer also needs to occupy a large inst...
