SUMMERY OF THE UTILITY MODEL
To the above situation, for overcoming prior art's defect, the utility model provides a double-deck drive (holding) chuck, effectual two people's cooperation of having solved when the installation of present big fan is being held up alone, screws up connecting bolt alone, complex operation has more defect, and motor center pin eccentric torsion is big, and flabellum, linking arm deflection are big, and life is short, the not high problem of security.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model discloses an outer (holding) chuck, fixing bolt, interior (holding) chuck, spring, blade linking arm mounting hole and drive shaft mounting hole, one side of outer (holding) chuck has interior (holding) chuck through the fixing bolt hookup, and the cover has the spring on the fixing bolt between outer (holding) chuck and the interior (holding) chuck, has all seted up a plurality of blade linking arm mounting hole on outer (holding) chuck and the interior (holding) chuck, and the drive shaft mounting hole has been seted up at the middle part of outer (holding) chuck.
Preferably, the number of the fixing bolts is six, and the fixing bolts are symmetrically arranged.
Preferably, the blade connecting arm mounting holes formed on the outer chuck and the inner chuck are three in one group and are arranged in a triangular manner or two in one group and are arranged in a straight line.
Preferably, the outer chuck and the inner chuck are both circular or polygonal.
Has the advantages that: when the utility model is used, the fixed bolt is prevented from loosening due to vibration by the installed spring, the limit clearance is flexibly adjusted, the construction and assembly are facilitated, the double-layer discs are arranged, the stress is dispersed, the stress concentration is avoided, the outer clamping disc and the inner clamping disc clamp the blade connecting arm to form a whole, and the stress of the fastening bolt of the single connecting arm is reduced; can spacing linking arm and blade through outer (holding) chuck and interior (holding) chuck, can install the blade alone, old style ordinary driving-disc needs two people's cooperations to hold up alone, screw up connecting bolt alone, construction installation effectiveness is improved, compact structure just reduces the focus of rotatory impeller, reduce the radial moment of swaying of gear motor axle, improve the speed reducer life-span, reduce the connecting bolt specification, only need a specification can realize the fixed of linking arm, reduce the error rate, numerical control laser cutting technology, high accuracy, need not mould structural adaptability, can reequip different quantity's blade according to customer's demand, even be a whole after through the bolt, this driving-disc makes the terminal sag of flabellum level reduce, alleviate motor center pin eccentric torsion, reduce the flabellum, linking arm deflection, improve the flabellum, linking arm life, the security is higher.
