Abstract
The invention relates to a mechanism for connecting a gear and a drive shaft. According to the mechanism, the gear is installed on a cone face portion of the drive shaft in a key mode, a locking nut is arranged on threads of a small radius portion of the cone face and the locking nut and the gear are pressed tightly together. An annular groove is formed in a gear side face covered by the locking nut and an annular flexible steel belt is fixedly embedded in the annular groove. Multiple conical head screws are screwed into the outer side of the locking nut in the circumferential direction and pointed tip portions of the conical head screws pierce into the plane of the annular flexible steel belt. The mechanism has the advantages of being reliable in work, long in service life of parts, capable of preventing equipment from abnormality and capable of hindering safety accidents.
Description
Technical field
The present invention relates to a kind of mechanical connection mechanism, be specifically related to the bindiny mechanism of a kind of gear and live axle, belong to mechanical engineering technical field.
Background technique
In mechanical engineering technical field, the bindiny mechanism of gear and live axle is generally by live axle, gear, key forms, wherein, direct geared is arranged on live axle, between gear and live axle, adopt key to position, although this gear and the bindiny mechanism of live axle have structure and the simple advantage of assembly technology, but, in long-term using process, continuous effect due to load, cooperatively interact and easily occur gap between the component of installing, this gap further can carried out in working procedure further acceleration, thereby cause equipment work unreliable, related components reduces working life, and likely cause equipment and cannot normally work, even likely cause serious security incident.
Summary of the invention
The object of the invention is to: for the existing above-mentioned defect of the gear of existing mechanical engineering technical field and the bindiny mechanism of live axle, the invention provides the bindiny mechanism of a kind of novel gear and live axle, overcome the existing above-mentioned defect of bindiny mechanism of existing gear and live axle.
The present invention realizes the technological scheme that above-mentioned purpose adopts: described a kind of gear and the bindiny mechanism of live axle, it is by gear, key, live axle, annular mild steel band, cone-head screw forms, it is characterized in that: gear is arranged on live axle by key, described gear and the matching part of live axle are conical surfaces, path position at live axle conical surface is shaped with screw thread, on described screw thread, locking nut is installed, together with described locking nut is pressed on gear, on the gear side covering at locking nut, be shaped with circular groove, in described circular groove, fixedly stud with annular mild steel band, in the outside of the corresponding locking nut of annular mild steel band, be along the circumferential direction screwed into some each cone-head screws, thrust in the plane of mild steel band at the tip position of described cone-head screw.
Beneficial effect: the present invention is owing to adopting after said method, thrust in mild steel band forcibly at the tip position of cone-head screw, so, make locking nut be not easy to rotate, in addition coordinating between gear and live axle is that mode with conical surface coordinates, cooperation is between the two tight, so, there is cooperation tighter, between component, be difficult for loosening, thereby can overcome therefrom causing of producing equipment work is unreliable, component reduce working life, may cause equipment cannot normally work, and even likely cause the defect of serious security incident.
