Description
Technical Field
The invention belongs to the technical field of mechanical transmission mechanisms, and particularly relates to a connecting structure capable of effectively eliminating a rotating clearance.
Background
The mechanical transmission mechanism is widely applied to production and life. The mechanical transmission mechanism is divided into rigid transmission and flexible transmission, and the rigid transmission comprises gear transmission, key transmission, cam transmission, link rod transmission and the like; the flexible transmission is classified into chain transmission, belt transmission, and the like. Most transmission mechanisms generate power loss due to friction and the like, and the service life of the transmission mechanism is shortened and the power consumption is increased along with heat generation side effects. The key transmission has no defects, but stress concentration is generated due to the existence of a key groove on the transmission shaft and the press mounting of the key.
The invention provides a mechanical connection transmission mechanism which is in rigid connection transmission and has the characteristics of small volume, no power loss and the like.
The invention is applied to a gapless connection structure between the output shaft and the rotating wheel of the rotary control servo mechanism. The rotary control servo mechanism is used for controlling the actuating mechanism to do rotary motion.
Disclosure of Invention
The invention aims to provide a connecting structure which enables materials to be elastically deformed to eliminate a transmission gap through interference fit of two wedge-shaped structures aiming at the defects of the prior art.
The technical scheme of the invention is as follows:
the utility model provides a can effectively eliminate running clearance's connection structure which characterized in that: comprises an output shaft, a rotating wheel, a bolt and a spring washer; the output shaft and the rotating wheel are fixed through bolts, and a spring washer is arranged between the bolts and the output shaft.
And oil wedge-shaped teeth are processed on the butt joint surface of the conveying shaft and the rotating wheel.
The conveying shaft and the wedge-shaped teeth on the rotating wheel are uniformly distributed in the circumferential direction.
The conveying shaft and the wedge-shaped teeth on the rotating wheel can be in seamless rigid connection and in interference fit.
The invention has the beneficial effects that:
(1) the end face tooth connection can realize seamless rigid connection of two parts.
(2) The coaxial connection allows for the loss-free transmission of forces or moments.
(3) The structure is simple and compact, and the realization is easy.

Detailed Description
The invention will be further described with reference to the following figures and examples:
a connecting structure capable of effectively eliminating a rotating clearance comprises an output shaft 1, a rotating wheel 2, a bolt 3 and a spring washer 4; the output shaft 1 and the rotating wheel 2 are fixed through a bolt 3, and a spring washer 4 is arranged between the bolt 3 and the output shaft 1.
And oil wedge-shaped teeth are processed on the butt joint surface of the conveying shaft 1 and the rotating wheel 2.
The conveying shaft 1 and the rotating wheel 2 are uniformly distributed in the circumferential direction.
The wedge-shaped teeth on the conveying shaft 1 and the rotating wheel 2 can be in seamless rigid connection and are in interference fit.
As shown in fig. 3, the output shaft 1 is connected with the rotating wheel 2 through a face tooth structure, and then the output shaft 1 (the output shaft is internally threaded) is connected and fastened with the rotating wheel 2 by a bolt 3 and a spring washer 4. After the output shaft 1 is connected with the end face tooth structure of the rotating wheel 2, the connection gap is eliminated through the elastic deformation of the end face tooth, so that the circumferential transmission and the reversing are free of gaps, and the transmission is stable.
