Description
Technical field
The utility model relates to a kind of axial direction positioning device, relates to a kind of axial direction positioning device of driving component specifically.
Background technique
In mechanical transmission structure, axially locating often adopts round nut to lock, with round nut lock washer locking (accompanying drawing 1).In actual application, because round nut circumference only offers four or six grooves (diameter of thread D >=M105 × 2) (accompanying drawing 2), after locking, the tongue of round nut lock washer is not corresponding with the fluting on round nut.For this reason, round nut usually needs to refund several angle, and the tongue of round nut lock washer just can be stuck in the groove of round nut.In more important transmission, due to refunding of round nut, certain gap can be produced, produce in transmission process and rock, cause vibration, noise, even cause the damage of driving component.
Summary of the invention
The purpose of this utility model provides a kind of axial direction positioning device that driving component is appropriately fixed for above-mentioned the deficiencies in the prior art part just.
The purpose of this utility model realizes by following technological scheme:
The axial direction positioning device of the utility model driving component comprises the stop collar being arranged on transmission shaft limited ring dais one side by key Placement, the driving component on stop collar is arranged on by fixed connecting piece, and the mode spinning be threaded connection is at the round nut for locating of another side of stop collar, 16 or 24 teeth groove are processed with in uniform mode around described round nut periphery, and the outboard end of a teeth groove in described teeth groove is fixedly installed positioning block by fixing bolt, described positioning block is spill fixture block structure, positioning block claw is inserted in teeth groove, another claw is inserted in axial draw-in groove that the transmission shaft that matches with round nut processes, at the round nut end face of side, fixing bolt mounting point, a caging bolt is installed, the head of described fixing bolt and caging bolt is processed with the through hole for installing spacing steel wire respectively, and fixing bolt is connected by the spacing steel wire installed in through-holes with caging bolt.
The through hole being opened in fixing bolt and caging bolt head in the utility model is made up of the through hole that two intersect.
The beneficial effects of the utility model are as follows:
The round nut that the utility model adopts circumference to have multiple groove combines with positioning block, can ensure the accurate location of driving component, fixing bolt and caging bolt be linked together with spacing steel wire, can be effectively locking, makes transmission more reliably, decreases mechanical failure.
